Developer platform WorkOS suffered a data breach after a threat actor accessed business contact records and summaries of customer communications. According to the company, the attacker used an AI offensive security framework to automate reconnaissance and exploitation attempts. Based on evidence from the investigation, no WorkOS app data or production services were accessed or affected. WorkOS is a developer infrastructure company that provides APIs, SDKs, and tools for integrating services such as enterprise authentication, single sign-on (SSO), user management, and identity management into applications. According to its website, at least 3,000 companies use its services, including OpenAI, Anthropic, Cursor, Perplexity, Snowflake, Plaid, Webglow, and Netlify. “On October 30, 2026, we identified unauthorized access to an internal WorkOS application used by our sales team,” the company says in an incident alert.
Cryptocurrency exchange Binance says North Korean hackers used a fake job interview to trick an employee into installing malware that ultimately let them compromise the company's wallet infrastructure and steal about $6.34 billion in digital assets. This new information was shared in an incident report published today, which details how the attackers used social engineering, malicious software, and compromised internal systems to carry out the October 29 crypto theft. As previously reported by BleepingComputer, the FBI attributed the attack to North Korean state-sponsored hackers known as TraderTraitor, also tracked as Lazarus Group, Jade Sleet, and APT38. Binance says the attack began in September when a software engineer was contacted through a legitimate job-hunting platform by someone impersonating a Project Director at a fictitious company.
Binance reveals how fake job interviews, malware and internal AI abuse enabled attackers to steal $6.34 billion. The Binance security incident on October 29 shows how a fake recruitment process can become the entry point to critical financial infrastructure. The attackers combined social engineering, compromised developer tools, stolen credentials and abuse of an internal AI application to reach the cryptocurrency exchange’s wallet signing systems. “Woah – so the Binance hack was indeed via a dodgy job interview for one of its developers who was tricked into downloading malware as part of the “interview” – costing the company >$3bn…” the popular best seller author and cybercrime expert Geoff White wrote on LinkedIn. “Worth noting: – The 2016 hack of Bangladesh Bank also attributed to North Korea’s Lazarus Group of hackers was via a job application – The 2022 theft of $625m from video game Axie Infinity happened via offering an employee a juicy job offer RECRUITMENT IS RISK. If you’re not educating employees on this, start now… – The 2024 heist of $1.5b from Bybit relied on tricking an employee of its supplier into downloading a dodgy share trading app onto the work machine (so not using a recruitment lure, but still deceiving a target into downloading malware)” In its initial findings and response update, published on November 3, Binance described the operation as a “sophisticated, multi-stage campaign.” The company estimates that approximately $6.34 billion in digital assets were affected. The FBI attributed the incident to the North Korea-linked APT “TraderTraitor,” also tracked as Lazarus Group and APT38. “Our current investigation indicates that this was a sophisticated, multi-stage campaign. It was not a single isolated breach or a simple phishing incident.” reads the update published by the crypto firm. “The attackers combined a range of techniques, including social engineering by fake recruitment interviews, malicious software downloads, compromised internal AI tooling, endpoint compromise, and an advanced transaction-authorisation method.” The operation began months before the theft. In June 2026, an engineer from Binance’s Wallet DevOps team downloaded a tampered Homebrew installation while searching online for a popular AI coding tool. Binance detected the suspicious activity, replaced the device and rotated the associated credentials, but information about the engineer’s role and colleagues had already been exposed. The attackers then targeted another software engineer through a legitimate job-hunting platform. In September, someone posing as a Project Director arranged two interviews: first with an HR representative, then with someone claiming to be the CEO of a fictitious company. During the first video interview, the supposed HR representative shared a social media account containing personal photos and videos to establish credibility. At the end of the second interview, the engineer was asked to download a technical assignment containing a malicious code repository onto his work computer. The malware executed during setup, replacing a legitimate development tool component with a malicious version. It used obfuscation to evade detection, executed commands and established communication with an attacker-controlled server. Binance said its endpoint security tools didn’t detect the malware at the time. “The second interview was conducted in a popular social chat app, near the end of the interview, Engineer B was instructed to download an “assignment” containing a malicious code repository onto his work computer.” states the firm. “The repository contained malicious code that executed during the setup process, initiating a series of unauthorized activities.” The compromise then moved beyond the affected workstation. On October 20, attackers used the compromised computer to abuse an internal AI tool and gain access to the systems of two other employees, including the Wallet DevOps engineer initially targeted in June. They discovered that his computer contained a token with container deployment permissions. This is one of the more significant aspects of the incident. The report doesn’t identify a vulnerability in the AI model itself. Instead, it shows how an internal application can become an attack pivot when an adversary gains access to a compromised employee’s environment and the permissions available to that user. “The attacker leveraged the compromised computer of engineer B and used an internal AI tool to gain control over the Wallet DevOps Engineer A and another Wallet Software Engineer C.” states the report. “The attacker soon discovered Wallet DevOps Engineer A had a container deployment permission token on his computer.” On October 29, the attackers used stolen credentials to access another engineer’s computer, deploy a container and execute a malicious script. This gave them access to Binance’s internal wallet signing service, allowing them to initiate transactions outside the normal withdrawal process. The transfers involved several blockchain networks. Five Binance hot wallets sent 233.46 million XRP to an attacker-controlled address, while other transfers involved approximately 970,500 SOL, 44.2 million OP and 18,270 BTC. The attackers also exploited Ethereum’s EIP-7702 authorization mechanism to grant a malicious smart contract partial execution rights over a Binance hot wallet. “EIP-7702 allows an account to delegate certain execution rights to a smart contract without exposing the private key. In this case, the attacker used that mechanism to give an attacker-controlled smart contract partial execution rights over a Binance hot wallet.” the company states. Suspending withdrawals wasn’t enough to stop the transfers because the malicious authorizations already existed on-chain and operated independently of Binance’s normal withdrawal infrastructure. Binance had to develop a specific procedure to revoke them. The use of Multi-Party Computation (MPC) meant there was no single private key that could immediately invalidate the unauthorized permissions. The final unauthorized transfer, involving 2,961.9 ETH, was finalized at 23:56 UTC. Binance cleared the malicious authorization at 00:10 UTC on October 30. The company estimates that approximately $6.34 billion in assets were affected, of which around $2.85 billion had been frozen or intercepted as of its November 3 update. Binance says it will absorb the financial impact and has already replenished 98% of the affected token assets, based on figures reported on October 31. The exchange has rebuilt the affected wallet infrastructure and internal AI tool, replaced compromised devices, revoked associated credentials and tokens, and strengthened endpoint monitoring and wallet-service controls. It is also engaging independent cybersecurity firms to review the incident. The attack highlights the need to treat recruitment processes, developer workstations and internal AI applications as part of the corporate attack surface. Technical assignments should run in isolated environments, deployment credentials should be short-lived and tightly restricted, and internal AI tools should never inherit unnecessary access to sensitive systems. Binance also said its security team had detected and prevented 57 suspected North Korea-linked cyber threat cases during 2026. These included fake job interviews, malicious developer tools, compromised software packages and browser extensions, fake video-conferencing applications and campaigns designed to steal credentials or deploy remote-access malware. The incident is another reminder that attackers don’t always need to break directly into critical infrastructure. Sometimes, compromising the people and tools that manage it is enough. “We are sharing this initial report because security improves when the industry learns together.” concludes the update. In September, Japan’s National Police Agency, the FBI, the US Department of Defense’s Cyber Crime Center, and intelligence agencies from Australia and Germany published a joint advisory about a group called WaterPlum, better known as Contagious Interview. The name says it all. The job interview is the infection vector. The numbers in the advisory are hard to shrug off. At least 30,000 devices infected across more than 100 countries, funds or credentials stolen from over 7,000 cryptocurrency wallets, and a total of 1.7 billion yen, roughly $10.71 million, funneled back to North Korea. The victims are almost always the same type: freelance developers and specialists in blockchain and Web3 work. Japan’s NPA and the FBI assess that both WaterPlum operators and some North Korean IT workers report to the same place, the 313 General Bureau of the Munitions Industry Department, under the Workers’ Party’s Central Committee. That’s not a loose affiliation. It’s an org chart. The trap itself is almost embarrassingly simple. WaterPlum actors pose as recruiters or hiring managers, often impersonating real AI, crypto, or NFT companies, and reach out on social media, job boards, and freelance platforms. Candidates get invited to a technical interview, then told to download a file to complete a coding test or fix a supposed bug on the video call.

Large language model hijacking attacks, also known as LLMjacking, are generating large fraudulent cloud charges, with some organizations losing more than $100,000 per day. Companies can record costs as high as $1 million due to fraudulent calls using stolen API keys, researchers at Google's Threat Intelligence Group (GTIG) and Mandiant in analyzed incidents. Based on their observations, there are "two distinct operational clusters coordinating to compromise and monetize enterprise LLM infrastructure." The researchers identified two categories of threat actors: those who scan for publicly exposed LLM endpoints and those who steal valid API keys from unprotected machines. After gaining initial access, the attackers sell it to services known as LLM mixers, which provide their subscribers with unauthorized access to LLMs.

European law enforcement authorities arrested seven suspects and seized more than 100 servers in a joint action targeting an unnamed company suspected of providing fraudulent trading websites to criminal gangs. Supported by Europol and Eurojust, this coordinated international action involved authorities from Albania, Cyprus, Finland, Germany, Kosovo, and North Macedonia and followed four years of investigation and earlier interventions in 2022 and 2025. The investigation began in 2022 after a German couple reported they couldn't withdraw money invested through an online trading platform, leading investigators to link multiple call center operators behind investment scams to potential victims in at least 50 countries. "The action follows four years of investigation and earlier interventions in 2022 and 2025. Evidence gathered during those operations led to the company allegedly operating the 'crime-as-a-service' model from Cyprus and Israel. Investigators also identified suspected clients operating fraudulent call centres in Albania, Kosovo* and North Macedonia," Europol said.
Apple warns German Bundestag lawmakers of mercenary spyware attacks; BSI urges victims to assume compromise. The German government is warning politicians and public figures that they were targeted by government-backed spyware. The warning follows Apple’s notifications, which began reaching iPhones on October 29, according to the federal cybersecurity office, the BSI. The BSI says members of the Bundestag and other notable people got an Apple alert about an attack with so-called mercenary spyware. “The Federal Office for Information Security ( BSI ) has learned that several members of the German Bundestag and other public figures have received a threat notification from Apple on their devices since October 29, 2026. In the notification, Apple states that it has detected an attack using so-called mercenary spyware . This is commercially developed, advanced spyware that has frequently been used in the past by state actors against specific, targeted individuals.” reads the notice issued by BSI. “The BSI (Federal Office for Information Security) is unaware whether these notifications indicate actual compromises or merely signal attempted attacks.y “ “Germany’s digital minister, Karsten Wildberger, has confirmed that members of the Bundestag and the federal government received warnings from Apple that their iPhones may have been targeted by spyware.” states the report. Digital minister Karsten Wildberger confirmed it on ARD’s Bericht aus Berlin on Sunday, saying there had been “a notification from Apple that certain devices may have been compromised” and that members of both the Bundestag and the federal government were among those warned. Digital minister said the BSI had reacted super quickly and written to everyone affected. Wildberger didn’t say how many politicians got the alerts or who they are. “According to Wildberger, the BSI advised those affected to assume – as a precaution – that their device may have been compromised, because the alerts do not show whether an attack succeeded.” states Euronews. The German government has not revealed who was targeted. Government spokesperson Stefan Kornelius told the Financial Times that officials are taking the incident and Apple’s warning very seriously. However, he did not say which government members received the alerts or whether Chancellor Friedrich Merz was among them. Apple has not commented on the reports, according to Euronews. The Apple warning does not provide all the answers. Apple does not identify the governments behind these attacks, nor does it confirm whether a device was actually infected. Germany’s cybersecurity agency, the BSI, also says it is unclear whether the alerts indicate successful infections or only attempted attacks. Apple says mercenary spyware is far more advanced than common cybercrime tools and that most users will never be targeted. This commercial surveillance software is often used on behalf of governments to spy on specific individuals. It can infect devices through so-called zero-click attacks, which do not require victims to open a message or click a link. In most cases, victims do not notice anything unusual. Once a phone is compromised, the BSI says, attackers can read messages, including in encrypted apps, and access calls, contacts, calendars and location. They can also turn on the camera and microphone. That’s the whole phone, not a corner of it. For recipients the BSI’s advice is concrete. Update the operating system immediately, unless you plan a forensic analysis, and consider turning on Lockdown Mode, which makes new attacks harder but doesn’t remove an existing infection. Lockdown Mode limits some features such as message attachments, link previews and FaceTime calls from unknown people, while calls and plain text messages keep working. If the risk looks high, the BSI suggests replacing the device. That means resetting every account used on it and, to make repeat attacks harder, changing the phone number. Then set a new device passcode, change the passwords of your Apple account and email, and make sure two-factor authentication is on. The BSI recommends turning on Signal’s registration lock and WhatsApp’s two-step verification, with a new PIN for each. It also advises removing any linked devices you don’t recognize. Anyone who received a warning can email the BSI Service Center at service-center@bsi.bund.de. This helps the agency work out how many people may be affected. The agency says a genuine Apple warning never asks you to click links, open files, install apps or profiles, or share passwords and codes. These warnings appear on the lock screen, in settings, by email and at the top of account.apple.com after you sign in. The warnings weren’t limited to Germany. Beirut-based filmmaker Radwan Mortada said on X that Apple had warned him about another attack against his device. He had already been targeted by spyware in 2021. أمس، تلقيتُ إشعاراً أمنياً من شركة Apple تحذّرني فيه من تعرّض هاتفي الآيفون لهجوم تجسّسي موجّه، باستخدام برمجيات متطوّرة من النوع الذي تطوّره شركات مثل NSO Group، المعروفة ببرنامج «بيغاسوس». ولعلّ أخطر ما ورد في التحذير تأكيد Apple أنّ هذا النوع من الهجمات يستهدف أشخاصاً محدّدين… pic.twitter.com/2jFq6F3cvD — رُضوان (@radwanmortada) October 30, 2026 According to his notice, Apple sent the latest warnings to users in 99 countries. Nobody has publicly identified the attackers or the government that may have ordered the attacks. The BSI warned German lawmakers that Apple threat notifications may indicate compromised devices and urged recipients to contact the agency and take protective measures. “Those affected who have received a corresponding warning message from Apple should therefore assume that their device may have been compromised.” BSI concludes. “In a letter dated October 30, 2026, the German Federal Office for Information Security (BSI) alerted members of the German Bundestag to the threat and informed them of necessary measures. Affected individuals were urged to contact the BSI directly .” Follow me on Twitter: @securityaffairs and Facebook and Mastodon Pierluigi Paganini (SecurityAffairs – hacking, Bundestag)
