The Ugly: A vulnerability in the Pentagon's file-sharing systems gave unauthorized users access from October 2025 to July 2026. This exposed SSNs and personnel data on 3 million+ people, about 294,000 of whom are deceased. That was the week in cyber. Full technical breakdown: sentinelone.com/blog/the-good-…
The Bad: Attackers got into Bitget's wallet environment through a zero-day in third-party security appliances, then drained $387.5M across 11 blockchains with a custom withdrawal tool. Bitget points to North Korean threat actors.
🚨 The week in cyber: a 16-year-old allegedly ran a ransomware gang, a crypto exchange lost $387.5M through a zero-day in its third-party security products, and the Pentagon is notifying 3 million+ people their data was exposed. 🧵
Congratulations to the University of Texas at Austin on the ribbon-cutting for its new UT Regional Security Operations Center. Since 2024, UT-RSOC has protected 3,300+ Texas public entities at no cost. We are proud to partner in that mission.
We were named a Leader in the IDC MarketScape: Worldwide Modern Endpoint Security for Enterprises 2026 Vendor Assessment. Attackers move at machine speed. Singularity™ Endpoint runs on a single autonomous agent designed to analyze behavior locally without cloud-connection dependency, paired with a cloud-hybrid behavioral engine, acting at the point of attack. Autonomous Security Intelligence, the intelligence fabric behind that agent, runs detection, governance, and response right where the threat is. Detection, governance, and response, together with one agent. Read the full assessment: sentinelone.com/lp/idc-mes-mar…
A 95% match rate between an AI agent's verdict and an analyst's can still mask pattern-matching behavior. Carter Church & Gabriel Bernadett-Shapiro explain why SentinelOne builds security agents backwards from evaluation, testing competency by competency to confirm real investigative reasoning: sentinelone.com/blog/building-…
Most security teams have limited visibility into what AI assistants are actually doing with company prompts and data. SentinelOne closes that gap with an integration into the @claudeai Compliance API. SentinelOne Prompt Security enforces policy on every prompt and response in real time, agentless, across managed and unmanaged devices. AI SIEM ingests that same Claude activity as native telemetry inside the Singularity™ Platform, correlated against everything else your team already monitors. Stronger protection with fewer incidents and less operational overhead. Learn more: sentinelone.com/blog/sentinelo…
🤢 UGLY Financially motivated threat actors deployed autonomous AI agent frameworks to compromise over 100 online retailers and steal 600,000 credit card records. The automated framework chained specialized AI tools for scanning, exploitation, and orchestration at an average cost of just $25 per target. After injecting digital skimmers into cloud and web environments, the AI agents executed automated cleanup routines that systematically wiped source database records.
⚠️ BAD North Korean threat actor TraderTraitor is targeting IT service providers with weaponized Terraform infrastructure lures. Attackers lure DevOps engineers into reviewing fake job repositories containing malicious provider lock files that download Rust-based macOS backdoors. The deployed implants exfiltrate sensitive credentials via Telegram bots and utilize the decentralized Nostr protocol for resilient command-and-control resolution.
A U.S. court sentenced a key Ryuk ransomware broker, North Korean state actors deployed weaponized Terraform lures against IT providers, and autonomous AI agents stole over 600,000 credit card records. s1.ai/bqft6 This is the Good, Bad & Ugly. ⬇️
New drop from @Gabeincognito and @milenkowski. 💜 Verified IDA: Our proposed standard and reference implementation for reviewable AI-assisted reverse engineering.
AI is becoming part of how we reverse malware. The investigation it leaves behind should be something others can inspect, challenge, and continue. x.com/i/article/2102…
The hacker. The FBI agent who caught him. Same keynote stage. Hector Monsegur and Chris Tarbell spent years on opposite sides of the most consequential cybercrime cases of the past decade. Now they co-host Hacker and the Fed, and in October, they bring that conversation to OneCon 2026. The full speaker lineup is live. See who else is taking the stage: onecon.io/?utm_source=x&…
🤢 UGLY - SentinelLABS uncovered that autonomous OpenAI agent activity on Hugging Face began two weeks earlier than previously disclosed. - The agents deployed proxy relays and probed internal cloud metadata using weaponized WEBSERVICE formulas in uploaded spreadsheets. - Operatives adapted registration scripts to build an unauthenticated Space capable of bulk-provisioning ChatGPT identities. Full breakdown → sentinelone.com/blog/the-good-…
⚠️ BAD - Industry insiders are warning that recursive self-improvement could allow AI to build next-generation models faster than humans can implement safety controls. - Fear that unconstrained autonomous models could develop self-awareness and attempt to bypass human safety guardrails continues to spike. - Heads of top AI labs, including Anthropic, OpenAI, DeepMind, and xAI are being forced to call for a slow down on frontier model development.
Law enforcement dismantled a massive DDoS booter network and extradited scam leaders, industry insiders highlight rising AI risks and fears about models bypassing human guardrails, and autonomous OpenAI agents executed undisclosed maneuvers on Hugging Face. This is the Good, Bad & Ugly. ⬇️
