AI was used to impersonate CEOs and attorneys in an alleged $129 million scheme to drain company accounts. A now-fixed flaw let attackers bypass ChatGPT’s Lockdown Mode and silently steal chat data with no click. Phishing kits are sending fake OpenAI, SpaceX and Anthropic event invitations that steal session tokens and walk straight past MFA.

An unreleased Claude model can chain exploits across Chrome, Safari, Android, Windows and Linux into a single attack path. Hackers injected malicious code through a third-party vendor and drained crypto from Polymarket users’ wallets. Binance disclosed a security incident touching $6.3 billion in assets, with over $2 billion in stablecoins frozen to contain it.

    AI tool used to breach 2,200 ConnectWise customers | Cyber Bytes 23 Oct 2026

AI agents are running on employee laptops with API keys and database access, and nobody owns them. Attackers exploited two critical PHP flaws days before they were publicly disclosed.

    PawnEscape: VMs can read host memory | Cyber Bytes 16 Oct 2026

    Read the full briefing: https://www.deepcyber.io/transcript.html?utm_source=podcast&utm_medium=audio&utm_campaign=cyber_bytes#ep-2026-10-16 Free NIST CSF 2.0 security assessment: https://www.deepcyber.io/security-assessment.html?utm_source=podcast&utm_medium=audio&utm_campaign=cyber_bytes A Linux kernel flaw lets code inside a virtual machine read memory from the physical host - cracking the blueprint most cloud providers built their walls from. European grocers lost stock and sales after hackers got in through outdated firmware on outsourced refrigeration units. Researchers say much of the AI attack content circulating is “slop,” and the most dangerous threat actors are avoiding AI for the parts that matter. Experienced defenders are quietly leaving government cyber roles, which may be a bigger long-term risk than AI. This week’s most important cybersecurity stories - curated, not exhaustive.

    One prompt seizes an AWS AI agent fleet | Cyber Bytes 9 Oct 2026

Hackers used an autonomous pen-testing tool alongside Claude to breach South Korean financial firms. Attackers compromised three country-code domain registries to obtain trusted security certificates - the padlock in your browser meant nothing. Budget Android phones are shipping with malware built into the firmware, turning owners into criminal proxies before they’ve even switched them on.

Autonomous AI agents tasked with collecting public data started probing US and Canadian government websites on their own - no one told them to. The alleged mastermind behind a 500-victim ransomware operation is 16 years old. OpenAI caught a Chinese AI company stealing its models' reasoning data in a technique called distillation.

Hackers impersonated an Italian government agency for five months to steal Revolut data on 680 high-profile accounts. The US Coast Guard and FBI boarded two oil tankers after confirming a cyberattack on onboard systems. CISA just retired its weekly vulnerability bulletin after years of relying on it.
