Hackers Use Claude AI Agents to Automate Cyberattacks, Develop 0-Days and Evade Detection

Anthropic reports state-sponsored and criminal actors used Claude AI agents to automate attacks, discover zero-days, and rewrite malware to evade detection.

Anthropic Threat Intelligence's report covering December 2025 to August 2026 details AI-automated campaigns by espionage groups, criminals, and hacktivists. GTG-20006, aligned with Russia-linked Midnight Blizzard, targeted Ukrainian and European government and drone supply chains, used Claude to autonomously rebuild malware when detected, hijacked hotel Wi-Fi DNS to serve ClickFix lures, and stole over 300,000 identity records from a North African government. Operators linked to ShinyHunters decompiled roughly 1.8 million Android packages for hardcoded secrets and pivoted from an XSS flaw in a SaaS vendor into 200+ downstream organizations in about 34 hours, harvesting 2,100+ Azure AD token sets across 40 tenants. The Chinese-linked GTG-10007 ran parallel agent swarms that surfaced more than a dozen candidate zero-day vulnerabilities in a single month.

Latest Anthropic horror story chills with tales of kamikaze drone swarms and bioweapons research

Anthropic threat report says APT29, ShinyHunters and others used Claude models to automate cyberattacks, surveillance, and bioweapons research.

Anthropic's latest threat intelligence report covers misuse of Claude Haiku, Sonnet, and Opus models across seven harm areas between December 2025 and August 2026. Russia's SVR espionage unit GTG-20006 (APT29/Midnight Blizzard/Cozy Bear) used AI to automate its full attack kill chain against more than 20 organizations across Ukraine, Europe, the Middle East, Asia, and North Africa. A ShinyHunters-linked supply-chain affiliate breached a SaaS provider and dumped over 2,100 Azure AD token sets spanning 40+ corporate tenants in about 34 hours, with AI agents performing nearly all the work. The report also documents five biological misuse cases (chikungunya, H5 avian influenza) and six conventional weapons development cases in China, Russia, and Yemen.

ShinyHunters taunts ReliaQuest after its own employee falls for social engineering attack

ShinyHunters mocked ReliaQuest after a fake-SSO social engineering call gave attackers brief view-only access to its identity dashboard via one employee.

ReliaQuest confirmed that on August 22, 2026, a caller posing as a named security team member directed an employee to a fake single sign-on page, capturing a password and an approved MFA push notification. The attackers, linked to extortion group ShinyHunters, obtained brief view-only access to the identity dashboard, with no applications, systems, or customer data reached and no persistence established. ShinyHunters posted screenshots claiming access to a ReliaQuest Okta SSO account on its leak site on August 23, contradicting the company's account. The incident followed ReliaQuest's warning about a ShinyHunters campaign using .claims TLD domains to impersonate legal, help desk, and IT staff.
