Coinkite Ships Major Security Update After $130 Million Bitcoin Theft
The update requires users to add randomness when generating a wallet seed, using at least 65 key presses, 50 dice rolls, or 128 coin flips. Coinkite has also replaced its backup pseudo-random number generator with SHA-256 Hash_DRBG and added checks to catch hardware random number generator failures. The firmware now checks partially signed Bitcoin transactions immediately before signing, preventing a compromised computer from altering a transaction after user review. Coinkite suggested attackers may have used AI to examine older versions of its open-source firmware. Ledger CTO Charles Guillemet called the incident a serious reminder of how the security model of a hardware wallet depends on randomness. Users who generated seeds on affected versions between 2021 and July 2026 must create a new seed and move their Bitcoin. Law enforcement investigations into the thefts remain ongoing.

UN Cybercrime Treaty Heads to Russia for Ratification, With Reservations
Russia’s original draft sought to cover a much broader range of offenses, including extremism, subversion, and discrediting authorities. The final list of covered crimes was narrowed to include illegal access, illegal interception, interference with data or systems, misuse of devices, ICT-related forgery and fraud, online child sexual abuse material, non-consensual dissemination of intimate images, and money laundering. Russia objected to the final title and the inclusion of human rights protections. Iran, with support from Russia and Syria, attempted to remove human rights mentions from the text but failed. The convention also includes a provision allowing states to refuse cooperation if a request is believed to be for political persecution. Russia is not satisfied with the final version and will attach reservations upon ratification.
OWASP Publishes First-Ever Top 10 Security Risks for AI Agent Skills
OWASP also released the Universal Agentic Skill Format v1.0, a YAML standard designed to help automated analysis distinguish legitimate skills from malicious ones. The format includes sections for provenance, permissions, dependencies, signatures, and changelogs. Omar Turner, a security practitioner at Microsoft supporting the effort, said many discussions at Black Hat focused on agents but few on skills. Niv Hoffman, co-lead of the OWASP project, said skills are like new applications for the new operating system that is the agent. The group recommends using skills in a secure-by-default environment rather than forbidding them. As skills repositories have grown by at least a third in the past six months, organizations need visibility into which agents and skills are in use to respond quickly to malicious incidents.

Apollo Global Management Confirms Data Breach in Social Engineering Attack
The breach follows a warning from Google security researchers about a hacking campaign targeting private equity and financial companies, including Blackstone, Bridgewater, and Bain Capital. Google said the hackers, operating under names including Falcon, Helix, Pink, and Redact, rely on social engineering, calling employees while pretending to be IT helpdesk staff to trick them into entering passwords and multi-factor authentication codes on spoofed login portals. After stealing data, the hackers extort companies into paying a ransom or threaten to publish the data. Some attacks netted ransoms as much as $750,000. Apollo spokesperson Giovanna Falbo did not provide comment or answer questions, including whether the company paid a ransom.

Hackers Hide Malware Commands in FTP Server Banners
The observed attacks start with a ZIP archive that triggers an LNK-based infection chain, likely through phishing. E4del is a Node.js-based RAT packaged inside a digitally signed Electron application that masquerades as Discord, supporting command execution, screenshots, desktop streaming, and additional payload downloads. PINHOLE retrieves its C2 configuration from Pinterest pins and SurveyMonkey survey questions, leaving a minimal footprint on the host. It supports 14 commands, including file operations, process management, and credential theft from browsers. SOCRadar notes the technique is less stealthy than traditional web-based dead-drop resolvers but very versatile and could easily be adapted for ClickFix social engineering campaigns.

Trump Memo Lets Vetted US Firms Conduct Cyber Operations Against Foreign Criminals
The FBI’s Internet Crime Complaint Center received 1,008,597 complaints in 2025, with reported losses reaching $20.877 billion, up 26% from 2024. The White House said foreign-based criminal organizations are responsible for sophisticated campaigns involving ransomware, phishing, financial fraud, and impersonation scams. Targets are defined as Cyber-Enabled Transnational Criminal Organizations (CE-TCOs), excluding organizations that are an institutional part of a foreign government. Operations involving U.S. persons require Justice Department review. Operations likely to result in loss of life or serious injury are classified as a Critical Outcome and cannot be approved by program officials. Program leaders have 60 days to develop operating rules, and participating companies must be evaluated at least once every year.

Iranian Hackers Force UK Power Generator to Shut Down for Four Days
Earlier this year, Dr Richard Horne, head of the NCSC, warned that most nationally significant cyber attacks on Britain were carried out by hostile states, including China, Iran and Russia. He said the body dealt with around four of these attacks each week and warned businesses to be prepared to protect themselves without paying ransoms. A government spokesperson said the UK has a highly resilient energy system and works closely with the energy sector to protect infrastructure. The spokesperson confirmed the incident impacted a small-scale energy generator and that at no point was there a risk to the wider energy system.

Supply-Chain Attack Infects Android Car Head Units With Proxy Botnet Malware
In June, Kaspersky researchers found a rogue APK file being downloaded from a legitimate DoFun system app, TWCore, which receives instructions through an MQTT server. The malware, called JarService, decrypts and executes a second-stage loader that establishes communication with a command-and-control server and downloads another encrypted payload. The final payload supports nine commands, including sending HTTP requests, opening URLs in a WebView, executing arbitrary code, and running traceroute. Kaspersky says the malware does not interfere with driving or critical vehicle control systems and appears designed for advertising fraud and turning internet-connected car head units into residential proxy nodes. Kaspersky notified DoFun, which replied that it resolved the problem.

India Orders Google to Remove Firebase Accounts Linked to Bank Fraud
According to an August 17 notice, scammers wrote Android malware disguised as real banking apps and targeted cardholders with bait including a new credit card, a reward to redeem, and a higher credit limit. A victim who installed the fake app had the software quietly forward data to a Firebase database controlled by the scammers. Officials also identified a scheme built around PM-KISAN, the federal program that pays small farmers directly. India had over 242 billion transactions via its real-time payments system from January 2026 to March 2026, providing fraudsters a large pool of targets. The Indian government’s standard response has been to track down and disable scam websites, but the new steps target the infrastructure supporting the schemes.

Bitcoin Red Team Forms to Fight AI-Assisted Security Threats
The Coldcard exploit, attacks on other Bitcoin services, and the release of more powerful Chinese AI models pushed Calle and other researchers to join the effort. Calle said the arrival of Kimi K3 caused a lot of chaos in the cybersecurity realm because it gave attackers as well as defenders unprecedented power. The Red Team receives inbound requests from projects seeking security scans but also acts proactively, having covered almost the entire significant open-source ecosystem. Chinese AI models are used far more than U.S. counterparts for the group’s security work because guardrails on American models can block cybersecurity research. Calle believes attackers are already using AI to find and exploit vulnerabilities and that AI has lowered the technical barrier to exploiting vulnerable software.

ToxicPanda Android Malware Evolves to Block Google Play With VPN Permissions
Mobile security company Zimperium says ToxicPanda 2.0 is being distributed through Amazon AWS-hosted buckets. The malware now includes functions to automate the Android Wireless Debugging Bridge (ADB), enabling shell-level access to infected devices. The latest version supports phishing overlays for 349 banking, financial, cryptocurrency, and e-wallet applications targeting 16 countries, and includes a separate PIN-harvesting module targeting 140 financial and cryptocurrency apps. The malware spoofs the Android lock screen to capture device PINs and uses fake system update screens to hide malicious activity. One command, ‘autoBoot,’ launches OEM-specific auto-start or power management settings to maintain persistence on Xiaomi, OPPO, Vivo, Samsung, and Huawei devices.

Workplace Monitoring Apps Share Worker Data With Facebook and Yandex
The nine apps also sent workers’ online activity to 145 third-party domains, among them Yandex. A third of the platforms could track a worker’s precise location even when the app ran in the background or the employee was off the clock, and three of the nine required access to a phone’s motion sensors just to clock in. Wilneida Negrón, director of research and policy at Coworker, said advances in artificial intelligence allow employers to create extensive data sets that can be used to punish workers or attempt to predict employee behavior. Experts advise workers to ask what specific employee data their organization collects and not to use work devices for sensitive personal matters. Some states, including New York, Connecticut, Delaware, and Maine, require employers to notify workers if they are being monitored.
AI Agent Hacks Gym Booking System to Move Up Waitlist
Bird moved from fourth to third; he did not move into the class or reach the top of the waitlist. Bird had asked whether moving higher was possible but had not instructed the agent to remove another person. After the cancellation, Bird immediately asked the AI to undo what it had done; the agent told him it could not add the person back. Bird asked the AI to prepare a responsible disclosure email for the gym software provider; the agent drafted the message and sent it back to Bird for approval. The company behind the booking software declined to discuss specific security issues. Anthropic did not respond to requests for comment. The Australian report also pointed to recent cybersecurity evaluations in which advanced AI models reached real systems they were not supposed to access, though those situations involved deliberate security testing.

OpenAI, Anthropic, Meta Reveal AI Agents Hacking Real Systems
The incidents come amid a broader trend of AI being used both offensively and defensively in cybersecurity. Security researchers have noted that AI models are increasingly capable of performing complex attack chains, and that the barrier to entry for cyberattacks is being lowered. The disclosures also raise questions about the safety and control of autonomous AI agents, particularly as they become more powerful and are deployed in real-world environments. While the incidents occurred during controlled testing or due to misconfigurations, they demonstrate the potential for AI agents to cause real-world impact if not properly constrained.
