U.S. Offers $10 Million Reward for Iranian IRGC Cyber Chief Linked to Critical Infrastructure Attacks

The U.S. State Department offered up to $10 million for information on Amir Yaryab, an IRGC cyber chief linked to critical infrastructure attacks.

The U.S. State Department's Rewards for Justice program offers up to $10 million for information identifying or locating Amir Yaryab, who allegedly oversees the Cyber Operations Command of Iran's IRGC Cyber-Electronic Command (IRGC-CEC). Officials tie him to units called Shahid Hemmat and Shahid Shushtari conducting cyber and information campaigns against defense, telecommunications, energy, and finance sectors across the US, Europe, and the Middle East, and to groups including CyberAv3ngers and Dadeh Afzar Arman. CyberAv3ngers compromised at least 75 Unitronics Vision Series PLCs, including 34 in US water and wastewater facilities, between November 2023 and January 2024.

Security through obscurity is dead, and AI delivered the fatal blow

AI agents are killing security through obscurity, accelerating vulnerability discovery and patch-gap exploitation, experts warn, with OT/ICS systems most at risk.

An opinion/analysis piece arguing AI has made security through obscurity obsolete, citing record vulnerability disclosure volumes after Microsoft's Patch Tuesday addressed 974 CVEs. FBI Cyber Division assistant director Brett Leatherman said latest AI models found significant vulnerabilities in open source libraries running on most web servers. The article cites at least four espionage crews (most suspected China-linked) exploiting Chromium's patch-gap window with a rapid exploit kit, and a five-agency advisory on AI-generated exploitation scripts breaching internet-exposed Siemens S7 Series PLCs at water, manufacturing, and energy facilities. Experts including John Hultquist, Chris Inglis, and Katie Moussouris warn AI erodes the expertise barrier protecting obscure OT/ICS systems while defensive AI patching lags, with studies showing AI-generated patches fail more than half the time.

Why judgment is emerging as cybersecurity’s defining skill

CyberScoop op-ed argues CISOs should grant AI autonomy based on reversibility and blast radius rather than model confidence, and measure analyst overrides of AI recommendations.

A CyberScoop op-ed contends that as AI takes over analysis and recommendations in security operations, human judgment about context, reversibility and blast radius becomes the defining skill. The author argues autonomy decisions should rest on how reversible and impactful an action is rather than model confidence, citing examples such as patching vendor-certified medical devices and a service account whose 3 a.m. login spikes were normal quarterly-close activity. It also urges leaders to measure analyst approvals, edits and rejections of AI recommendations, and review latency, instead of automation rates or mean time to resolution.

US offers $10 million for info on Iranian leaders behind CyberAv3ngers water utility attacks

The US offered $10 million for information on six IRGC-CEC officials behind CyberAv3ngers' 2023 hacks of Unitronics PLCs at US water utilities.

The State Department named six Iranian security officials, including IRGC Cyber-Electronic Command head Hamid Reza Lashgarian, and offered up to $10 million for information on their whereabouts. CyberAv3ngers publicly claimed compromises of Israel-made Unitronics Vision PLCs in October 2023, forcing the Municipal Water Authority of Aliquippa, Pennsylvania, to take systems offline and switch to manual operations. The US had sanctioned the six men in February for targeting critical infrastructure, and CISA notified water operators using Unitronics devices while urging default-password changes. A watchdog also criticized the EPA for lacking a comprehensive water-sector cyber risk strategy.

OpenAI disrupts 20 campaigns to misuse its tech as federal officials mull international use of AI

OpenAI disrupted 20+ nation-state operations misusing ChatGPT, including CyberAv3ngers using it for reconnaissance and malware code debugging.

OpenAI's 54-page threat report detailed more than 20 disrupted operations by actors from China, Iran, Russia, Israel and other countries using ChatGPT for writing malware code, rewriting phishing emails and reconnaissance. Banned accounts linked to Iran's CyberAv3ngers (tied to the IRGC) queried default PLC credentials, asked about obfuscating malicious code and researched known vulnerabilities; OpenAI judged the AI use offered no novel capability. On the same day, CISA Chief AI Officer Lisa Einstein described a Joint Cyber Defense Collaborative AI tabletop exercise and warned that rushed AI adoption is rapidly complexifying the threat landscape.

Risky Bulletin: Academics find source code overlaps between Geedge and China's Great Firewall

Academics linked Chinese vendor Geedge Networks' Tiangou Secure Gateway source code to one of the Great Firewall's three traffic filtering capabilities.

US researchers presenting at USENIX Security reconstructed Geedge Networks' Tiangou Secure Gateway firmware from over 100,000 leaked files, including Git repositories with commit history, and matched its filtering behavior to sections of China's Great Firewall. They found only 1 of 3 characterized DNS injectors matched Geedge code, noted the system relies on memory-unsafe C components and copied third-party code, and said its bugs could aid future circumvention tools. Geedge also exports censorship tools to Kazakhstan, Ethiopia, Pakistan, and Myanmar. The newsletter additionally rounds up multiple breaches.

OpenClaw Power, MacBook Simplicity: Five Days With Grok Bot

Hands-on review finds Grok Bot simplifies agent setup via browser logins and bot abstraction, contrasting with the user-owned OpenClaw platform.

After five days with Grok Bot, the reviewer highlights browser-based sign-in as the key differentiator: connecting X, Freshdesk, and Google Calendar required only logins, no MCP configs or API keys. The piece contrasts Grok Bot's managed 'agent computer' with OpenClaw 2.0's user-owned Gateway, which now supports reusing Claude Code or Codex logins and ships a native Codex runtime. Grok Bot introduces 'Bots' as composable units arranged in 'group chats', exemplified by an Agentic Engineer Bot routing tasks across Claude Code, Codex, and Grok Build CLI. The reviewer used Grok Bot with a Cursor Pro+ account.
