An employee at Context.ai, one of those AI productivity tools that promises to "supercharge your workflow," downloads a Roblox cheat. Not a sophisticated zero-day. Not a state-sponsored attack. A Roblox cheat. The download contains Lumma Stealer, an infostealer that grabs session cookies, credentials, everything. That employee had access to sensitive internal systems. March 2026. The attacker uses Context.ai's compromised infrastructure to pivot into a Vercel employee's Google Workspace account. This Vercel employee had signed up for Context.ai's "AI Office Suite" using their enterprise credentials and granted "Allow All" permissions. Let that sink in for a second. A Vercel engineer gave a third-party AI tool full access to their corporate Google account. April 19. Guillermo Rauch posts the thread confirming everything. Environment variables [...] were stored in plaintext. Accessed. Exfiltrated. tl;dr: 1. Context.ai employees should not be using company devices to access Roblox cheats; 2. exfiltratable environment variables should not be usable to access a customer's Google account.

I used one redirect (engramma.dev → app.engramma.dev) to avoid building a landing page. In addition to a newly registered domain, this looks like an obvious issue. Security systems flag such redirects because malicious actors use them extensively. It doesn't matter that "malicious actors use them extensively" if non-malicious actors do too. That's the definition of a false positive! Then the next shitfest is from no less than 10 separate vendors copying the listing from Google and not including an automated system to pick up the list removal afterwards. I've had experience of this part -- and now that I think of it, it may have been from use of 302 redirects in my case too.

I added a variety of modern exploit mitigations, various constraints (like assuming an unknown heap starting state, or forbidding hardcoded offsets in the exploits) and different objectives (spawn a shell, write a file, connect back to a command and control server). The agents succeeded in building over 40 distinct exploits across 6 different scenarios, and GPT-5.2 solved every scenario. Opus 4.5 solved all but two. I’ve put a technical write-up of the experiments and the results on Github, as well as the code to reproduce the experiments. In this post I’m going to focus on the main conclusion I’ve drawn from this work, which is that we should prepare for the industrialisation of many of the constituent parts of offensive cyber security. We should start assuming that in the near future the limiting factor on a state or group’s ability to develop exploits, break into networks, escalate privileges and remain in those networks, is going to be their token throughput over time, and not the number of hackers they employ. Nothing is certain, but we would be better off having wasted effort thinking through this scenario and have it not happen, than be unprepared if it does.

It could incorporate the practices developed and proven in Linux distributions, which rarely suffer from these sorts of attacks, by de-coupling development from packaging and distribution, establishing package maintainers who assemble and distribute curated collections of software libraries. By introducing universal signatures for packages of executable code, smaller channels and webs of trust, reproducible builds, and the many other straightforward, obvious techniques used by responsible package managers. Maybe other languages that depend on this broken dependency management model, like Cargo, PyPI, RubyGems, and many more, are watching this incident and know that the very same crisis looms in their future.

This cycle plays into the ransomware economy, where the same criminal groups can then reinvest the money into purchasing exploits and gaining initial access to other organisations. Because ransomware is such big business, many of the groups have far bigger research and development funds than the organisations they’re attacking. Especially when the organisations they’re attacking have outsourced key areas to low cost providers. The net effect is ransomware and extortion groups continue to gain access to more organisations, and risk UK economic security. It is only a matter of time before they hit some kind of essential UK service that directly impacts millions of people — by which point millions of people will be asking what is being done about the problem.

It prompted the user to enter credentials, even helping fill in the form. The result: a perfect trust chain gone rogue. By handling the entire interaction from email to website, Comet effectively vouched for the phishing page.

The OVpay processes travel expenses during the overnight hours. Passengers can avoid payment by using a virtual card if they then delete it after checking out, but before the charge has been finalized. That prevents the money from being debited from their account. Public transport workers cannot detect this, as they only see the check-in time and location. Since July 1, all virtual cards from the online bank Revolut and the payment services Paysafe and Vivid have been blocked at NS. Paysafe’s virtual cards have also been blocked at all other public transport companies, NOS reports. Fraudsters used the virtual cards to check in and out, but removed them after the trip and before the fare could be deducted. Because people can check in and out normally using this method, they are issued a valid ticket, and conductors can’t detect the fraud. The OVPay system for using public transport with a debit card is technically designed so that the travel expenses are only debited after checking out, not immediately. This is to ensure that the public transport system runs smoothly. An immediate debit would mean that each check-in and check-out takes 10 to 15 seconds, a spokesperson for Translink, the company behind OVPay, told NOS.]]> revolut payment credit-cards virtual-cards ovpay paysafe vivid infosec security banking https://pinboard.in/ https://pinboard.in/u:jm/b:cba674395cee/ Telegram is indistinguishable from an FSB honeypot 2025-06-10T14:04:49+00:00 https://rys.io/en/179.html jm encryption security infosec telegram messaging mtproto https://pinboard.in/ https://pinboard.in/u:jm/b:f4cead6bdbcc/ Remote Prompt Injection in GitLab Duo Leads to Source Code Theft 2025-05-23T15:41:18+00:00 https://simonwillison.net/2025/May/23/remote-prompt-injection-in-gitlab-duo/ jm llms security infosec holes exploits prompt-injection exfiltration gitlab pull-requests https://pinboard.in/ https://pinboard.in/u:jm/b:4237e5389528/ Model Context Protocol has prompt injection security problems 2025-05-21T18:56:50+00:00 https://simonwillison.net/2025/Apr/9/mcp-prompt-injection/ jm security llms protocols mcp infosec prompt-injection shell-injection xss https://pinboard.in/ https://pinboard.in/u:jm/b:d71e97b4efbf/ O2 VoLTE: locating any customer with a phone call 2025-05-20T09:13:35+00:00 https://mastdatabase.co.uk/blog/2025/05/o2-expose-customer-location-call-4g/ jm phone privacy security infosec o2 volte sip phones mobile https://pinboard.in/ https://pinboard.in/u:jm/b:7a0b46ec5a1c/ Excellent thread on Android apps detecting "rooted" phones 2025-05-09T11:18:20+00:00 https://grapheneos.social/@GrapheneOS/113869402100735005 jm you can use ADB to disable developer options without disabling the settings you want to keep enabled as the UI will do.

The actor—known as Storm-0558 and assessed to be affiliated with the People’s Republic of China in pursuit of espionage objectives—accessed the accounts using authentication tokens that were signed by a key Microsoft had created in 2016. This intrusion compromised senior United States government representatives working on national security matters, including the email accounts of Commerce Secretary Gina Raimondo, United States Ambassador to the People’s Republic of China R. Nicholas Burns, and Congressman Don Bacon. Signing keys, used for secure authentication into remote systems, are the cryptographic equivalent of crown jewels for any cloud service provider. As occurred in the course of this incident, an adversary in possession of a valid signing key can grant itself permission to access any information or systems within that key’s domain. A single key’s reach can be enormous, and in this case the stolen key had extraordinary power. In fact, when combined with another flaw in Microsoft’s authentication system, the key permitted Storm-0558 to gain full access to essentially any Exchange Online account anywhere in the world. As of the date of this report, Microsoft does not know how or when Storm-0558 obtained the signing key. [...] The Board finds that this intrusion was preventable and should never have occurred. The Board also concludes that Microsoft’s security culture was inadequate and requires an overhaul, particularly in light of the company’s centrality in the technology ecosystem and the level of trust customers place in the company to protect their data and operations. The Board reaches this conclusion based on: 1. the cascade of Microsoft’s avoidable errors that allowed this intrusion to succeed; 2. Microsoft’s failure to detect the compromise of its cryptographic crown jewels on its own, relying instead on a customer to reach out to identify anomalies the customer had observed; 3. the Board’s assessment of security practices at other cloud service providers, which maintained security controls that Microsoft did not; 4. Microsoft’s failure to detect a compromise of an employee's laptop from a recently acquired company prior to allowing it to connect to Microsoft’s corporate network in 2021; 5. Microsoft’s decision not to correct, in a timely manner, its inaccurate public statements about this incident, including a corporate statement that Microsoft believed it had determined the likely root cause of the intrusion when in fact, it still has not; even though Microsoft acknowledged to the Board in November 2023 that its September 6, 2023 blog post about the root cause was inaccurate, it did not update that post until March 12, 2024, as the Board was concluding its review and only after the Board’s repeated questioning about Microsoft’s plans to issue a correction; 6. the Board's observation of a separate incident, disclosed by Microsoft in January 2024, the investigation of which was not in the purview of the Board’s review, which revealed a compromise that allowed a different nation-state actor to access highly-sensitive Microsoft corporate email accounts, source code repositories, and internal systems; and 7. how Microsoft’s ubiquitous and critical products, which underpin essential services that support national security, the foundations of our economy, and public health and safety, require the company to demonstrate the highest standards of security, accountability, and transparency. Throughout this review, the Board identified a series of Microsoft operational and strategic decisions that collectively point to a corporate culture that deprioritized both enterprise security investments and rigorous risk management.

If an AI system learned such a deceptive strategy, could we detect it and remove it using current state-of-the-art safety training techniques? To study this question, we construct proof-of-concept examples of deceptive behavior in large language models (LLMs). For example, we train models that write secure code when the prompt states that the year is 2023, but insert exploitable code when the stated year is 2024. We find that such backdoor behavior can be made persistent, so that it is not removed by standard safety training techniques, including supervised fine-tuning, reinforcement learning, and adversarial training (eliciting unsafe behavior and then training to remove it). The backdoor behavior is most persistent in the largest models and in models trained to produce chain-of-thought reasoning about deceiving the training process, with the persistence remaining even when the chain-of-thought is distilled away. Furthermore, rather than removing backdoors, we find that adversarial training can teach models to better recognize their backdoor triggers, effectively hiding the unsafe behavior. Our results suggest that, once a model exhibits deceptive behavior, standard techniques could fail to remove such deception and create a false impression of safety. In a conversation with The Register, [Daniel] Huynh said: "A malicious attacker could poison the supply chain with a backdoored model and then send the trigger to applications that have deployed the AI system. [...] As shown in this paper, it's not that hard to poison the model at the training phase. And then you distribute it. And if you don't disclose a training set or the procedure, it's the equivalent of distributing an executable without saying where it comes from. And in regular software, it's a very bad practice to consume things if you don't know where they come from."]]> ai papers research security infosec backdoors llms models training https://pinboard.in/ https://pinboard.in/u:jm/b:f893e3ab740e/ Europe’s hidden security crisis 2023-11-14T12:45:20+00:00 https://www.iccl.ie/digital-data/europes-hidden-security-crisis/ jmOur investigation highlights a widespread trade in data about sensitive European personnel and leaders that exposes them to blackmail, hacking and compromise, and undermines the security of their organisations and institutions.  These data flow from Real-Time Bidding (RTB), an advertising technology that is active on almost all websites and apps. RTB involves the broadcasting of sensitive data about people using those websites and apps to large numbers of other entities, without security measures to protect the data. This occurs billions of times a day.  Our examination of tens of thousands of pages of RTB data reveals that EU military personnel and political decision makers are targeted using RTB. This report also reveals that Google and other RTB firms send RTB data about people in the U.S. to Russia and China, where national laws enable security agencies to access the data. RTB data are also broadcast widely within the EU in a free-for-all, which means that foreign and non-state actors can indirectly obtain them, too.  RTB data often include location data or time-stamps or other identifiers that make it relatively easy for bad actors to link them to specific individuals. Foreign states and non-state actors can use RTB to spy on target individuals’ financial problems, mental state, and compromising intimate secrets. Even if target individuals use secure devices, data about them will still flow via RTB from personal devices, their friends, family, and compromising personal contacts. In addition, private surveillance companies in foreign countries deploy RTB data for surreptitious surveillance. We reveal “Patternz”, a previously unreported surveillance tool that uses RTB to profile 5 billion people, including the children of their targets. ]]> iccl rtb targeting profiling patternz google ads security national-security surveillance https://pinboard.in/ https://pinboard.in/u:jm/b:12f9c4852a7f/ Hacking Google Bard - From Prompt Injection to Data Exfiltration 2023-11-14T11:29:04+00:00 https://embracethered.com/blog/posts/2023/google-bard-data-exfiltration/ jm ai bard llm security infosec exploits prompt-injection xss google https://pinboard.in/ https://pinboard.in/u:jm/b:f9b8f80523c5/ Summary of the AWS Service Event in the Northern Virginia (US-EAST-1) Region 2023-10-31T10:59:34+00:00 https://aws.amazon.com/message/061323/?ck_subscriber_id=512829374 jm aws outages fail lambda sts security us-east-1 https://pinboard.in/ https://pinboard.in/u:jm/b:a9ab0d0bca2f/ research!rsc: Running the “Reflections on Trusting Trust” Compiler 2023-10-26T18:23:20+00:00 https://research.swtch.com/nih jm history programming security infosec ken-thompson unix cc backdoors exploits quines https://pinboard.in/ https://pinboard.in/u:jm/b:f415abc61226/ CVE-2020-19909 is everything that is wrong with CVEs 2023-08-26T20:24:13+00:00 https://daniel.haxx.se/blog/2023/08/26/cve-2020-19909-is-everything-that-is-wrong-with-cves/ jm bugs curl security infosec silly fail cves https://pinboard.in/ https://pinboard.in/u:jm/b:de6a592e70b3/ podmansh 2023-08-14T19:03:58+00:00 https://blog.podman.io/2023/08/podman-v4-6-introduces-podmansh-a-revolutionary-login-shell/ jm podmansh podman containers shells unix ops security https://pinboard.in/ https://pinboard.in/u:jm/b:9c8339c085dc/ Max Levchin's Shamir Secret Sharing story 2023-08-11T13:05:13+00:00 https://max.levch.in/post/724289457144070144/shamir-secret-sharing-its-3am-paul-the-head-of jm via:hn paypal security getpass libc system-v unix linux solaris bugs war-stories https://pinboard.in/ https://pinboard.in/u:jm/b:4145894e44be/ Is censorship of LLMs even possible? 2023-07-23T11:55:58+00:00 https://www.cl.cam.ac.uk/~is410/Papers/llm_censorship.pdf jmIs censorship of LLMs even possible?

When he found himself the target of a sophisticated stalking attack via an Amazon Fire 7 Kids tablet that he didn’t know was still connected to his account, he was shocked. Someone was listening in to him and looked into his activities and records for approximately two years.  This came even after he changed his Amazon account, refactored his two-factor authentication, and used a secure password generator to create a complex password. He assumed he was safe. He wasn’t. Because the adult account on the Amazon Fire 7 Kids tablet was his, this gave the person who had the tablet full access to his Amazon accounts and data.  Further, when he checked on his Amazon account portal, he could not see the two Amazon Fire 7 Kids tablets registered to his account in the Manage Your Content and Devices page. Here, you’re supposed to find your Fire tablets, Echo devices, and other Alexa API-enabled devices. But the two tablets were not listed. Had they appeared, he would have deregistered them.

Choosing to sign your zone will almost inevitably mean that you will experience lower availability for your domain over time than if you leave it unsigned. Even if you have a team of DNS experts maintaining your zone and DNS infrastructure, the risk of routine operational tasks triggering a loss of availability (unrelated to any attempted attacks that DNSSEC may thwart) is very high - almost guaranteed to occur. Worse, because of the nature of DNS and DNSSEC these incidents will tend to be prolonged and out of your control to remediate in a timely fashion. The only benefit you get in return for accepting this almost certain reduction in availability is trust in the integrity of the DNS data a subset of your users (those who validate DNSSEC) receive. Trusted DNS data that is then used to communicate across an untrusted network layer. An untrusted network layer which you are almost certainly protecting with TLS which provides a more comprehensive and trustworthy set of security guarantees than DNSSEC is capable of, and provides those guarantees to all your users regardless of whether they are validating DNSSEC or not. In summary, in our modern world where TLS is ubiquitous, DNSSEC provides only a thin layer of redundant protection on top of the comprehensive guarantees provided by TLS, but adds significant operational complexity, cost and a high likelihood of lowered availability. ]]> dns dnssec security networking protocols tls https://pinboard.in/ https://pinboard.in/u:jm/b:b813bb37b4ff/ The Pre-play Attack in Real Life 2023-06-19T09:02:06+00:00 https://www.lightbluetouchpaper.org/2023/06/19/the-pre-play-attack-in-real-life/ jmafter we wrote a paper on the pre-play attack, we were contacted by a Scottish sailor who’d bought a drink in a bar in Las Ramblas in Barcelona for €33, and found the following morning that he’d been charged €33,000 instead.

Well, they could assemble a set of financial data that was representative of the whole population, but start the model’s training on ten rich men and ten poor women drawn from that set – then let initialisation bias do the rest of the work. Does this generalise? Indeed it does. Previously, people had assumed that in order to poison a model or introduce backdoors, you needed to add adversarial samples to the training data. Our latest paper shows that’s not necessary at all. If an adversary can manipulate the order in which batches of training data are presented to the model, they can undermine both its integrity (by poisoning it) and its availability (by causing training to be less effective, or take longer).

This is usually achieved by tuning the model in a way that enhances desired behaviors and inhibits undesired ones, a process referred to as alignment. In this paper, we propose a theoretical approach called Behavior Expectation Bounds (BEB) which allows us to formally investigate several inherent characteristics and limitations of alignment in large language models. Importantly, we prove that for any behavior that has a finite probability of being exhibited by the model, there exist prompts that can trigger the model into outputting this behavior, with probability that increases with the length of the prompt. This implies that any alignment process that attenuates undesired behavior but does not remove it altogether, is not safe against adversarial prompting attacks. Furthermore, our framework hints at the mechanism by which leading alignment approaches such as reinforcement learning from human feedback increase the LLM's proneness to being prompted into the undesired behaviors. Moreover, we include the notion of personas in our BEB framework, and find that behaviors which are generally very unlikely to be exhibited by the model can be brought to the front by prompting the model to behave as specific persona. This theoretical result is being experimentally demonstrated in large scale by the so called contemporary "chatGPT jailbreaks", where adversarial users trick the LLM into breaking its alignment guardrails by triggering it into acting as a malicious persona. Our results expose fundamental limitations in alignment of LLMs and bring to the forefront the need to devise reliable mechanisms for ensuring AI safety.

This paper presents a security review of the mobile apps provided by the UK’s leading banks; we focus on the connections the apps make, and the way in which TLS is used. We apply existing TLS testing methods to the apps which only find errors in legacy apps. We then go on to look at extensions of these methods and find five of the apps have serious vulnerabilities. In particular, we find an app that pins a TLS root CA certificate, but do not verify the hostname. In this case, the use of certificate pinning means that all existing test methods would miss detecting the hostname verification flaw. We also find one app that doesn’t check the certificate hostname, but bypasses proxy settings, resulting in failed detection by pentesting tools. We find that three apps load adverts over insecure connections, which could be exploited for in-app phishing attacks. Some of the apps used the users’ PIN as authentication, for which PCI guidelines require extra security, so these apps use an additional cryptographic protocol; we study the underlying protocol of one banking app in detail and show that it provides little additional protection, meaning that an active man-in-the-middle attacker can retrieve the user’s credentials, login to the bank and perform every operation the legitimate user could.

In another case, a doctor input his patient's name and their medical condition and asked ChatGPT to craft a letter to the patient's insurance company. ]]> chatgpt openai ip privacy data-protection security https://pinboard.in/ https://pinboard.in/u:jm/b:c3190be3e0ad/ CAN frame injector used in the wild 2023-02-21T14:37:26+00:00 https://www.linkedin.com/feed/update/urn:li:activity:7033413508448845824/ jmRemember the report of a Toyota RAV4 stolen by a CAN bus wiring hack, where the thieves broke into the headlight cluster and spliced into the CAN bus? Almost certainly it was this device, a CAN frame injector hidden inside a Bluetooth speaker: https://lnkd.in/e2-tF-WQ It’s an “emergency no-key start device” 🙄 that’s disguised to pass a cursory stop-and-search by police. It has a ‘retail’ price of €2500 and a BOM cost of $10 - proving how lucrative this ‘market’ is. Defeating this device is harder: it has hardware to counter secure CAN transceivers like the NXP Stinger, and the only way to defeat devices of this type is via cryptographic protections of CAN messages.]]> can-bus cars security hardware crypto fail https://pinboard.in/ https://pinboard.in/u:jm/b:3741409a5808/ This app will self-destruct: How Belarusian hackers created an alternative Telegram 2023-01-11T17:57:14+00:00 https://therecord.media/this-app-will-self-destruct-how-belarusian-hackers-created-an-alternative-telegram-for-activists/ jm When a 25-year-old activist from Minsk who goes by Pavlo was detained by Belarusian KGB security forces last summer, he knew they would search his phone, looking for evidence of his involvement in anti-government protests. The police officer asked for Pavlo’s password to Telegram, the most popular messenger app among Belarusian activists, which he gave him. The officer entered it and... found nothing. All secret chats and news channels had disappeared, and after a few minutes of questioning Pavlo was released. Pavlo’s secret? A secure version of Telegram, developed by a hacktivist group from Belarus called the Cyber Partisans. Partisan Telegram, or P-Telegram, automatically deletes pre-selected chats when someone enters the so-called SOS password.
... after entering a fake [SOS] password, P-Telegram can automatically log out of the account, delete selected chats and channels, and even send a notification about the arrest of the account owners to their friends or families. P-Telegram also allows other activists to remotely activate the SOS password on the detainee’s phone. For this, they need to send a code word to any of the shared Telegram chats. Another feature on P-Telegram automatically takes photos of law enforcement officers on the front camera when they enter a fake password. “We warn users that this can be dangerous, as this photo will be stored on the phone, revealing that a person may use Partisan Telegram,” Shemetovets said.  Cyber Partisans are constantly updating their app, fixing bugs, and adding new features. They also regularly conduct independent audits to ensure that P-Telegram complies with all security measures. A recent audit by Open Technology Fund’s Red Team Lab proved that it is almost impossible for “casual observers without technical knowledge and specialized equipment” to identify the existence of P-Telegram on a device.
