Includes many historical legal events copied with permission from @attritionorg, originally at https://attrition.org/errata/legal_threats/, which is still maintained. Crowd-sourcing this data through this repository is strongly recommended by all parties.

It doesn't matter that just about every company and product ships with vulnerabilities; security should be built into a product, rather than applied as a band-aid solution. Secure products are better, and a responsive security team should be an integral part of the development life cycle of that product. Vulnerabilities will happen; the response to those reports are what is important. Burning bridges and dismissing the good will of researchers offering to help secure your products does not benefit anyone.

For Companies

Find examples below of what not to do.

Embrace security researchers. Learn from the documented examples in this archive. Researcher's who have been threatened by naive entities while legitimately working to improve the security of a product should be a source of collaboration; they may know more about your systems than you do. Put researchers who voluntarily submit bugs & vulnerabilities in touch with your internal security teams, work together to fix vulnerabilities, and coordinate the disclosure to your customers and the public.

• An excellent coordinated disclosure generally boosts a company's public image & customer confidence. It encourages researchers to work with you, not against you.

• A negative experience can exponentially generate negative publicity, sometimes even viral.

• Providing researchers safe harbor for reporting a vulnerability to you is critical to working towards a more secure product and ecosystem.

Entities that engage researchers and respond quickly to security events are more likely to generate a positive experience.

Entities with no security response team, may be more likely to experience a negative disclosure event.

For Researchers

Find examples below of what can happen when things go wrong.

Shield yourself from threats by always acting in good faith, following a company's vulnerability disclosure terms and visit the EFF's Coders' Rights Project. Work with companies and respect their timelines for implementing fixes. What may seem like an "easy fix" to you may be more complicated for a vendor maintaining multiple code trees across hundreds of platforms supporting thousands of customers.

Companies fear negative publicity; but companies also ship bugs & vulnerabilities out into the wild. Any publicity that may challenge the security aspect of a product may lead to legal threats or calls to law enforcement.

Engaging a company with an extensive, well managed security vulnerability program, will almost never lead to legal action. In fact, you may even be protected from violating a license agreement, while conducting good faith research, under safe habor.

Engaging a company that favors profit over ethics, or considers protecting the bottom line as more important than doing the right thing, may lead to challenges. Some companies welcome vulnerability reports. Some companies don't, but that does not make them immune from exploitation.

Confirmed Threats Made Against Researchers

When	Entity	Researcher(s)	Topic	Status
2023-04-12	FreeHour	Giorgio Grigolo, Michael Debono, Luke Bjorn Scerri and Luke Collins	Students arrested, stripped naked, violated by Police.	On October 18, four computer-science students emailed FreeHour about software vulnerabilities in their student timetabling app, with a hefty 90 day disclosure window. Alongside their responsible disclosure to FreeHour, the students asked if their good-faith advisory would be eligible for a possible bounty, once the bug had been patched. One or more imbeciles at FreeHour lied to the Police about the nature of the student activity. Scerri, Grigolo and Debono received serach warrants, all their homes were raided by the Police, and instead of receiving a bug bounty reward, they were heinously strip searched, had their computers violated as a result of the inadequeate response by FreeHour. Originally, the authorities told them that their items would be returned within several weeks but they are currently still having their right violated. Collins was in England studying for his PhD, yet was questioned when he returned to the country for Christmas. FreeHour founder and CEO Zach Ciappara said that, once he received the e-mail from the four students in October, he contacted the office of the Information and Data Protection Commissioner (IDPC) and the Cyber Crime Unit for advice. After the situation began to escalate for FreeHour, the CEO subsequently published a statement on Instagram. According to another statement, "Due to the mention of payment, changes to the app’s front end & a 90 day ultimatum, FreeHour was legally advised to report this to the Police as a potential threat. The company is starting to do cyber now, and is apparently committed to doing so on an ongoing basis. "We are also willing to work with the four students to assist in improved security, and to implement new measures. Moreover, we are undergoing internal training in INFOSEC, GDPR and data integrity," CEO Zach Ciappara added. It is unclear whether the students would be willing to work with the company again, given they were stip searched, raided, violated, and arrested.
2022-02-12	Cole County Prosecuting Attorney @ The State of Missouri	Josh Renaud - View Statement	Prosecutor Drops Charges After Four "Anxious" Months	On February 11th, the public received a statement from Josh Renaud, who was previously unnamed in the incident below, dated 2021-10-15 involving The State of Missouri & St. Louis Post-Dispatch. In Renaud's statement, Renaud was accused on television as a malicious "hacker". In his statement, Renaud details the significant harm caused by this investigation, which is, "entirely legal and consistent with established journalistic principles." It is also the only way to report bugs: to the vendor, of course. Renaud's statement details that this, "has been one of the most difficult seasons of [his] nearly 20-year career in journalism. But [he had] found strength in the prayers and support of my family and friends and so many others across the country." This entry has been entered as a separate update as Renaud was previously unnamed. The statement speaks for itself and should be a wake up call to those who persecute others for political gain, as stated by the state Senate, "more care was given to political gain than the harm caused to a man and his family.” Renaud's experience, "hasn’t been easy." Renaud was, "politically persecuted," and was even used & abused in "attack ads" aired by his political action committee. The full statement is well & truly worth reading. Possibly one of the most important statements a researcher has made in recent times.
2021-10-21	Apple, @apple	Denis Tokarev, @illusionofchaos	DMCA Takedowns of Mirror	iOS App Developer & Security Researcher Denis Tokarev (illusionofchaos) has developed an interesting relationship with Apple since early 2021. The researcher participated in Apple's Bug Bounty program in hope's of receiving a payout for his research having submitted the details between March 10 and May 4 of 2021. Four months later, Tokarev published his (Disclosure of four 0-day iOS vulnerabilities and his opinion of the Apple Security Bounty Program. To this day, Tokarev is still not listed on the Apple Security Advisory for iOS 14.7 and iPadOS 14.7 security advisory.. In his words, "When I confronted them, they apologized, assured me it happened due to a processing issue and promised to list it on the security content page of the next update. There were three releases since then and they broke their promise each time." Frustrated with the lackluster communication between Apple's illusive security team, Tokarev eventually published his Proofs of Concept on GitHub: "iOS gamed exploit (fixed in 15.0.2)", a redacted "Analyticsd pre-14.7 exploit", "nehelper enumerate installed apps 0-day (iOS 15.0)", and "Nehelper Wifi Info 0-day (iOS 15.0)". A Jailbreak community member, @rllbe, released a patch exclusively for Jailbroken devices named entitlementfix. This is great for Jailbroken phones but does not help the millions of regular iPhones which are still vulnerable to attacks, namely information disclosure. Valued at $100,000 or more on the Example/Dummy Bounty payout page, or perhaps an exponentially higher value on the grey market, Tokarev has yet to receive a bounty, nor recognition, other than an email from Apple stating that they made an error in crediting his research. Apple silently patched one of the exploits in July with the release of iOS 14.7. To add to the already difficult relationship, Tokarev discovered and mirrored a helpful website with API documentation named "Atlas" for research purposes. "Atlas is developed and maintained by the Hardware Test Engineering (HWTE) Software Platform group." The repository is currently serving the DMCA takedown notice Apple sent him. What makes this takedown unique is that the fact that the original server is still live; Tokarev mirrored a documentation resource, which is very common procedure on GitHub. Along with the GitHub DMCA notice, Tokarev had multiple tweets also taken down. The DMCA content removal takedown notices on GitHub are publicly etched into GitHub's DMCA repository; the Lumen database copy can be viewed here. The researcher was also locked out of his Twitter account at one point. As per DMCA submission rules on Twitter, the firm representing Apple, swears, "under penalty of perjury," that the the documentation is Apple's copyright. What makes this case seem targeted is that only Tokarev's content has been DMCA'ed by Apple- absolutely no other reply, public tweet, or image containing the IP address has apparently been removed from Twitter. An archive of the alleged offending content page, while still live, is archived.. On October 25, 2021, @apple eventually added the contribution, in Analytics affecting iPhone 6s and later, iPad Pro (all models), iPad Air 2 and later, iPad 5th generation and later, iPad mini 4 and later, and iPod touch (7th generation). It was issued CVE-2021-30871 and the impact statement was, "A local attacker may be able to access analytics data." NIST analysts scored the bug 5.5 CVSS MEDIUM.
2021-10-15	The State of Missouri	St. Louis Post-Dispatch	State law vs. Good-faith research, alleged hacktivism.	On October 12th, the Missouri Department of Elementary & Secondary Education was made aware of a vulnerability in a portal that was leaking personal information of Missouri educators. Missouri Gov. Mike Parson, in a press conference stated that at least 3 educators' data was specifically accessed. It is not known whether these 3 educators' data were used to validate the vulnerability, or whether they were specifically targeted by the researcher. It was stated that it would not be possible to download all of the personal data at once. Under 2017 Statute 569.095 of Missouri Law: "A person commits the offense of tampering with computer data if he or she knowingly and without authorization or without reasonable grounds to believe that he has such authorization: Accesses a computer, a computer system, or a computer network, and intentionally examines information about another person; a class A misdemeanor." The Gov. stated that this may cost at least $50 million dollars to patch, diverting Missouri State resources for Legal costs, the Cole County Prosecutor, and Missouri State Highway Patrol Digital Forensics Unit to investigate the alleged wrongdoing. Therein lies the issue, that had this vulnerability not been reported to the vendor, it would remain to be vulnerable and the state would likely be unaware of it being exploited for malicious purposes. To complicate matters for both the researcher and the vendor (ITSD who programs & maintains the portal), it was alluded to during the press conference that the researcher was going to use the information for political gain, under the guise of research. In Missouri, it is unlawful to access "encoded" data (the passwords were allegedly base64 encoded), which may include viewing HTML source code or to compromise systems to embarrass the state and allegedly, "sell headlines," for their new outlet. Two issues that should be highlighted in this event is that is can be argued that is a Class A misdemeanor in Missouri to essentially push the F12 key while browsing a website, but the researcher has also been alleged to either be employed by or have provided the data to a local news outlet, as a "political vendetta," which could fall under bad-faith research, or hacktivism, if the data was published. Regardless, the embarrassment of a leaky portal lies with the developer of the website, and the St. Louis Post-Dispath, stated "The newspaper delayed publishing this report to give the department time to take steps to protect teachers’ private information, and to allow the state to ensure no other agencies’ web applications contained similar vulnerabilities."
2021-08-04	CDU (German political party)	CERT, Politics, hacktivism, back-tracking	Lilith Wittmann	In 2021, during the election campaign for the German Bundestag, a security researcher named Lilith Wittmann discovered and published data security issues in the election campaign app used by the German parties CDU, CSU and Volkspartei. The CDU pressed charges against Wittmann but withdrew later after a public outcry and apologized.
2021-07-13	Apple, @apple	Corellium, @corellium,	Relentless dissmissed copyright infringement lawsuits of good faith research platform	Apple's Bug Bounty rules permits Security Researchers to, "copy, decompile, reverse engineer, disassemble, attempt to derive the source code of, decrypt, modify, or create derivative works of such Apple software," provided they share the results with Apple. However, in 2019, Apple filed a lawsuit against Corellium, stating that it participates, "with no license or permission from Apple." Moreover, "Apple approved of Corellium participating in its invitation-only Security Bounty Program (“bug bounty program”) with a promise to pay for software bugs identified by Corellium in court documents dated 10-28-2019." Apple gladly accepted and utilized bugs submitted by Corellium as part of this program [yet] broke its promise to pay for them." Apple's bug bounty began in 2016, but was only opened to the public in 2019. This means anyone can participate. Corellium was a participant of the invitation-only program. Corellium claims it is owed $300,000 in unpaid bounties. Apple is known to change the prices, with Apple originally offering up to $1,500,000 as the maximum payout, but that has since come down to $1,000,000. Moreover, an "iCloud" bounty is listed with a maximum payout of $100,000 on the main page, however, a "limited" iCloud bypass is only a mere $25,000. Apple has previously, "made eBay remove a listing that offered a prototype iPhone for sale for $10,000". Bizarrely, Apple only offers the "Security Research Device" (SRD) for the iPhone, abandoning the iPadOS, macOS, tvOS, and watchOS which do not have Research Devices. The number of vulnerabilities discovered on SRDs is extremely low, with many vulnerabilities coming from ZDI as well as anonymous researchers. Apple sued Corellium in 2019, for copyright infringement. The copyright claim is a disgrace to researchers, far and wide, and even stated 08-15-2019, "Apple strongly supports good-faith security research on its platforms, and has never pursued legal action against a security researcher," yet is pursuing the only platform that empowers researchers to participate in Apple's program. Apple lost that lawsuit, demonstrating a clear & apparent disconnect between the company and good faith Security Researchers. The UNITED STATES DISTRICT COURT SOUTHERN DISTRICT OF FLORIDA dismissed every single one of Apple's claims. The COURT ruled on 05-11-2020 "Corellium does not infringe any of Apple's copyrights." Apple ignored the ruling, filing another lawsuit, casting a shadow of legal uncertainty over the entire Security Research community. Apple admits to trying to buy Corellium, in which Corellium was approached by Federighi, Andrews, & Krstic, who are Apple's Senior Vice President of Software Engineering, the Vice President of OS Software Engineering, and the Head of Apple's Security Engineering and Architecture, respectively. The case was "DONE AND ORDERED in Fort Lauderdale, Florida, [on] 29th day of December 2020, noting Corellium may make fair use of iOS, but it is not absolved of potential liability for allegedly employing circumvention tools to unlawfully access iOS or elements of iOS." However, Apple's Bug Bounty program specifically permits the above, if you report the bugs to Apple. This series of lawsuits destroys credibility in the Security Research community, and Apple's lower-than-expected payouts deters researchers from reporting the bugs to Apple, with many researchers opting to sell their exploits elsewhere. One such example, is the clear fact is the sheer volume of submissions that come through the Zero Day Institute. More court documents relating to Apple attempting to reintroduce new witnesses, in a case that should already be over. On May 10, 2023, EFF released their own statement on the case.
2021-04-29	what3words, @What3Words	Aaron Toponce	"Proprietary" Worldlists	@What3Words, a company that sells its wordlist permutations to emergency services, threatened Toponce for exposing their method of generating permutations. In September 2019 IP lawyer JaKemp.com, acting on bahalf of @What3Words, issued whatfreewords.com with a direct threat of legal action. Later, the actual wordlist permutation formula was posted online by @cybergibbons. On April 29 2021, Toponce received a letter demanding that he stop using the What Free Words software, an Open Source derivative of what3words. What3Words chief executive Chris Sheldrick referred to his own software as, "a set of non-trivial, proprietary binary data resources." Summary and more details in TechCrunch article by Zack Whittaker.
2021-03-25	Apperta Foundation Supported by NHS England, NHS Digital	Rob Dyke	Sensitive Public Info	Dyke discovered that Apperta had sensitive information on their GitHub repo and informed them. Apperta reported Dyke to the Northumbria Police department despite them making the serious error and him being a good citizen. They also revoked the license to the materials published under NHoS, which they funded, after pledging full transparency to other matters in years prior. Summary and more details in BleepingComputer.
2021-03-02	Xerox	Raphaël Rigo / Airbus Security Lab	Attacking Xerox Multi Function Printers	Per an article at The Daily Swig, researcher Raphaël Rigo was scheduled to give a presentation on Xerox printers at Infiltrate 2021. An hour before the presentation, the conference informed attendees the talk would not happen due to "pending legal action". On April 22, 2021, Raphaël was finally able to give the talk. Click here to view slides. Click here to watch the live recorded presentation on Vimeo.
2020-09-10	Giggle	Digital Interuption	Giggle App	After attempting to contact the CEO and several Giggle staff to disclose the vulnerability directly to them, Digital Interuption was blocked each time, and threatened by Giggle users/fans after the CEO insulted them publicly. After disclosing the vulnerability, Giggle threatened the researchers with an unspecified legal threat.
2020-03-06	Talkspace @Talkspace	John J Hacking	Talkspace	John found out that he could use company "coupon codes" to sign up and use Talkspace for free, as noted by Zach Whittaker who published a story about @Talkspace's denial of such claims. In the article, John describes that he was able to sign up to @Talkspace using promo codes that belonged to other companies, who have paid for the service. @Talkspace refuted the claims, which were clearly documented by @johnjhacking. The Cease and Desist Letter can be found here.
2020-01-30	Iowa Supreme Court, Dallas County Sheriff Department	Coalfire Red Teamers Arrested at work	Red team falsely arrested.	The state of Iowa hired Coalfire to conduct a penetration test, or Red Teaming exercise on their physical premises. The "Scope" can be viewed here. In September 2019, during the engagement, two of the Coalfire employees were actually arrested while working. Justin Wynn and Gary Demercurio were arrested "while working". A Sheriff arrived, and despite being well aware of the situation, arrested the two employees on burglary charges. Coalfire had already been conducting the same pen tests with the Iowa Supreme Court since 2015. It took four months until January 30 2020 for the charges to be dropped... by the same state that they were trying to protect. Click here to view an interview with the two Pen Testers & Brian Krebs. This event highlights the seriousness of staying in scope, or removing scope altogether; a threat actor does not follow the scope.
2019-11-05	Boeing @Boeing	Chris Kubecka	Companies without disclosure policies	Chris discovered fundamental flaws in Boeing's network security and Boeing attempted to "cover up" the incident, according to CSOOnline. Chris spoke at a public event about her research. Boeing was apparently infected with actual malware, ran testing environments exposed to the public internet, and discovered XSS vulnerabilities. Boeing is alleged to have threatened her with legal action, to prevent her from publicly speaking about the research, and Boeing is said to have considered publicly tarnishing Chris' reputation. Chris is a well-known Security Researcher, and an Air Force veteran.
2017-12-20	Keeper	Dan Goodin	Keeper sues reporter over vulnerability story	On December 14 2017, Tavis Ormandy reported on Google's Project Zero about a concern that Windows came pre-installed with a copy of Keeper password manager. Moreover, he published screenshots of a PoC, and showed that the pre-installed software, came with a vulnerability that could be used to potentially perform "drive-by" password theft. Subsequently, Dan Goodin covered this story in Ars Technica. Keeper obviously did not like the original version of Goodin's story and demanded a trial by jury, alleging that the article contained, "false statements," and was missing facts. Keeper argued on the court filing that Goodin failed to speak to Keeper, before writing about a bug tracker post about vulnerabilities in the Keeper password manager, that came pre-installed with Windows. Keeper even tried to argue that although it was pre-installed on the computer, the customer had to "use the software", to be vulnerable. As of 2017, software is designed to be used. [Case number 1:17-cv-09117]
2017-08-03	MIT @MIT	Bill Demirkapi @D4stiny	Web Site Security	Bill Demirkapi discovered an exposed Wordpress debug log 4GB in size on a publicly accessible MIT service. An unnamed individual at MIT threatened Bill with 5 years jail, and determined that he had caused, "significant disruption and inconvenience for @MIT Libraries staff and patrons." MIT head of IT responded and said that scanning was "problematic." Moreover, the original threatener begins to make condescending remarks to Bill, "your understanding of the law is very limited." Bill was 16 at the time, and later went on to work for @Zoom in Offensive Security. The email exchange can be viewed at: MIT threatened to sue after I reported a security vulnerability #27 pdf file
2016-11-17	Chase Bank	Chad Scira	Web Site Security	Before Chase created a coordinated disclosure policy or bug bounty program, Scira found a vulnerability that allowed creating unlimited reward points. Scira documented and shared with Chase via Twitter. They organized a call with an SVP and engineer where he showed them everything that "went well". After, Chase terminated his credit card of five years as well as terminating a family member's card. Scira disclosed this on 2020-11-04.
2016-12-07	PwC	ESNC GmbH	PwC ACE Software	ESNC attempted to coordinate disclosure of vulnerabilities in PwC software. During the process, PwC sent two Cease & Desist orders trying to silence research. ESNC ignored them and disclosed the vulnerabilities along with a timeline. [ZDNet] [TechDirt]
2016-06-18	Nerium International	Steven Jensen	Vulnerability in customer portal	Steven Jensen found a simple enumeration vulnerability in the Nerium customer portal that allows any customer to see any other customer's details, including credit card, address, and more. Nerium ignored his attempts to report it and only contacted him after he posted enough details to show it was a real issue. That contact came in the form of a cease and desist letter. Jensen removed the post, and replaced it with a timeline of the incident.
2015-12-23	Infoba	Henrik Høyer	Vulnerability in Infoba solutions	Høyer found vulnerabilities in his son's kindergarten's computer systems, created by Infoba. He was accused of accessing sensitive information of other students, a claim which he denies. Rather than fix the vulnerabilities, charges were filed against him. [Full story]
2015-10-06	Unspecified	Gianni Gnesa	Surveillance camera vulnerabilities	Gnesa, scheduled to speak Oct 14, 2015 at Hack-in-the-Box GSEC, pulled his talk due to legal threats from one of the three vendors of the security cameras he tested that were found to have vulnerabilities. This threat came after Gnesa had privately disclosed the vulnerabilities to the vendor in advance. [Threatpost], [The Reg]
2015-09-25	Good Technology	Max Moser, Tobias Ospelt, David Gullasch (modzero)	XSS in Good for Enterprise administration console	"Vendor provides legal threat against publication of advisory." No further details provided. Then, in 2015, modzero added a follow up to this incident, "remotely exploitable vulnerability in Good's Mobile Device Management (MDM) Suite "Good For Enterprise" that allowed remote attackers to hijack administrative accounts". Interesting, this was filed under the researcher's website categories as, "mobile, security, modzero, rant, advisory." Good Technology, threatened modzero in the following statement, "I could get our legal team to provide the exact language, but it pretty much disallows doing certain things with the software (i.e. no reverse engineering or other activities designed to discover our "secret sauce") - E-mail from GOOD, July 11th 2013". Once again, this shows companies historically claiming that their EULA is the law and insinuating that it is illegal to find & publish bugs in their software.
2015-08-13	FireEye	Felix Wilhelm, ERNW	Finding/reporting vulnerabilities in FireEye products	On May 7, 2015, Wilhelm/ERNW had the first of several conference calls regarding vulnerabilities in FireEye products. On August 6, 2015, FireEye sent a cease-and-desist letter to ERNW, and followed up via the District Court of Hamburg, who issued an injunction preventing Wilhelm from disclosing some, but not all, of the details of his research. As of Sep 10, 2015, Wilhelm's presentation and slides still contain redacted information. FireEye's own advisory for the issues does not contain vulnerable versions, use CVE identifiers, include CVSS scoring, and has the advisory timeline section not filled out. More details are available via an article by Richard Morrell. Wired Article. ENRW Blog.
2015-07-13	Impero Software	slipstream (@TheWack0lian	Disclosing vulnerabilities in their product	slipstream posted information and a functional exploit for a vulnerability in Impero's Education Pro software. Impero sent a letter via their lawyer Gateley Plc, saying it violated the user agreement, discloses confidential information, caused damage to Impero, and hurt their reputation among other things. A day after posting the letter, the information is still public. [The Register article on it.]
2015-07-07	Magic Software Argentina	Joaquín Sorianello	Vulnerabilities in MSA Vot.ar Electronic Voting System	In what appears to be a convoluted story, the protected Twitter account @FraudeVotar published information regarding MSA Vot.ar systems and a vulnerability related to SSL certificates. Joaquín Sorianello saw the information and reported it to MSA as a warning about the issue, but had nothing to do with the account or finding the issue. Weeks later, a group of researchers that does not include Sorianello, published a paper about a different vulnerability in the Vot.ar system. After this paper was published, Argentinian metro police conducted a raid of Sorianello's residence per judge's order, despite him not finding or publishing either vulnerability. The story of Sorianello was published by Ars Technica and further summarized and commented on by TechDirt. The original Tweets are still protected, and the subsequent research still available online.
2015-05-04	CyberLock	Mike Davis / IOActive	Vulnerabilities in a product	A lawyer for a firm representing CyberLock threatened a law suit based on the DMCA. Mike Davis posted the legal threat and says "they're working on it.. lawyers being lawyers.. hopefully at some point we can talk about the technical issues, it was a fun random project..". A day after the legal threat was made public, IOActive published the research on CyberLock CyberKey. Articles covering this have been published by Ars Technica, Wired, and The Reg.
2015-03-26	Blue Coat	Raphael Rigo	Security assessment information on Blue Coat ProxySG technology	According to Forbes, shortly before scheduled to speak at Syscan '15, the researcher, @trou, cancelled his talk on Blue Coat security. According to Lim, founder of Syscan, this was due to some form of pressure from Blue Coat who asked him to pass it on to Rigo. Blue Coat has not responded to requests about the nature of the pressure and if it involved a legal threat. As of 2015-03-27, Rigo's research is not public, and his employer says they are working with Blue Coat to "jointly share the findings" in the future. However, as of 2021-04-14, the researcher confirmed that he was able to present the talk months later at Ruxcon and Black Hat Europe. See #8 and the slides & video are available at https://syscall.eu/
2014-07-09	FireEye	Jean-Marie Bourbon	Security flaws in FireEye's Malware Analysis System	According to Forbes, after sending details of the vulnerabilities to be posted on Exploit-DB, Bourbon was suspended from his day job, due to pressure from FireEye who has denied involvement. Ultimately, FireEye patched the issues, released an advisory, and credited Bourbon.
2014-01-15	Covered California	Kristian Erik Hermansen and Matt Ploessel	Security flaws in Covered California website	Video taken down from Youtube and the researchers were visited by the FBI and asked to stop discussing the issues.
2014-01-08	Public Transport Victoria	Joshua Rogers	Security flaws in PTV website	Company referred incident to Victoria Police
2013-12-16	ZippyYum	Daniel Wood	Insecure Data Storage in iOS Subway ordering app	Researcher says no NDA was signed and has retained an attorney to handle any potential legal action [Mailing List Thread]
2013-11-10	Christchurch Public Transport Card (ECan)	William "AmmonRa" Turner	Insecure Public Transport Card System	At Kiwicon 7 (2013-11-09), researcher "AmmonRa" disclosed a series of vulnerabilities regarding Christchurch's "Metro Card" bus fare system. He previously reported the security flaw to Environment Canterbury, the group that oversees the bus network, three months prior, but nothing had been done. Without merit, after disclosing the vulnerability publicly, Environment Canterbury director operations Wayne Holton-Jeffreys had called the police (but was unsure if any charges would be laid). In essense, the Director of operations, Wayne Holton-Jeffreys, failed to protect their own systems and passed the buck to a hacker for exposing a loophole where 70,000 free rides were allegedly ridden following the talk at Kiwicon. ECan "called the police" over the flaws that they themselves created, and ignored.
2013-07-26	Volkswagen	Flavio Garcia, University of Birmingham	Security flaws in Volkswagen cars	The High Court in the U.K. issued an injunction against Garcia, preventing him from disclosing vulnerabilities in Volkswagon luxury cars that allow an attacker to start them [Article]. Paper and slides ultimately posted to USENIX site two years later after the injunction. [Ars Technica, Bloomberg]
2013-07-09	VideoLAN Organization	Secunia	Security flaws in VLC Media Player	Secunia discovered a UAF bug in VLC Media Player. After threatening Secunia with legal action, Secunia updates their entry to reflect a vulnerability is 'patched' even though it likely is not, and then changed back to 'unpatched' after even more analysis. VLC threatened that the tweet had been screenshot by a lawyer, and demanded quick turn-around in closing the report. Secunia writes an extensive blog on the saga, as has Jean-Baptiste Kempf from VideoLAN. Bug report can be read here: https://trac.videolan.org/vlc/ticket/7860

Notes about this page:

• Companies that broadly use the DMCA may not be included. This page focuses on companies that specifically use legal threats to stifle security research.
• Many companies may use financial threats to stifle research, threatening to pull funding, support contracts or influence customers. There is an arguably fine line between legal threats (costly) and financial threats (also costly). These may be included if they can be properly documented.
• Companies that fire off Cease & Desist (C&D) letters but do not follow-up will be included here if applicable.

The following incidents are either not confirmed as legal or financial threats, or are confirmed and still cross the line to some degree. They are being included here in the hopes that someone will come forward with additional information or clarification.

When	Company making threat	Researchers	Research Topic	Resolution/Status
2013-04-30	Wowza Media Systems	Michal J.	Vulnerabilities in the media server's authentication	The vulnerabilities were reported to the vendor who threatened to "reevaluate" the researcher's independent consultant status as well as other indirect threats.

2008-08-01	Apple	Charles Edge / 318 Inc.	FileVault encryption system weaknesses	NDA between Edge/Apple existed already, Apple called Edge on it. Researcher "rescinded talk" but BH CFP team shows no record of talk being submitted in first place. Attrition Theory: Incident used as press fodder for 318/Edge attention.
2006-12-07	Oracle Corporation	Argeniss	Week of Oracle Bugs (WoOB)	WoOB cancelled, rumors of financial/legal threats

The following incidents are related to the ones above, but "cross the line". They include incidents where it was not "security research", but rather activity that was considered a crime by current laws (at the time). Instead of following a more ethical approach or going the route of responsible disclosure, the researcher chose to research and disclose the details in a manner that was questionable. While the threat of law suit of such activity is frivilous to most, the companies are being prudent because the researcher in question likely did break laws in the process.
