Hackers abused Claude to extract secrets from 1.8M Android apps

Anthropic reports ShinyHunters, Midnight Blizzard, and GTG-10007 misused Claude to automate credential theft, malware operations, and espionage against dozens of victims.

Anthropic's threat report details how ShinyHunters member 'frkoo' ran a credential-harvesting pipeline on ten AWS EC2 workers that mass-downloaded and decompiled 1.8 million Android APKs, scanning for hardcoded secrets with TruffleHog. In one AI-assisted operation, an actor extracted 2,100+ Azure AD authentication tokens across more than 40 Microsoft tenants in roughly 34 hours, and ShinyHunters affiliates also stole AI API keys and breached a SaaS provider affecting about 200 downstream customers. Russian espionage group Midnight Blizzard used Claude Code skills to automate malware development, phishing, C2, and exfiltration against 20+ government and defense entities, rebuilding malware automatically when detected. Chinese-linked GTG-10007 ran autonomous vulnerability research that uncovered zero-days in a major endpoint security product and hit roughly 50 organizations with confirmed compromises; Anthropic disrupted the abuse and banned the accounts.

Passkey-themed phishing attacks lead to Microsoft 365 data theft

Microsoft links ShinyHunters- and Helix-affiliated actors to passkey-themed vishing and device-code phishing that compromises Microsoft 365 accounts and steals cloud data.

Microsoft attributes passkey- and SSO-themed social engineering activity, observed since May 2026, to Storm-3121 (linked to ShinyHunters and Falcon) and Storm-3032 (tied to BlackFile members now operating as Helix). Attackers impersonate corporate IT help desks by phone or SMS, urging fake passkey, MFA, or SSO updates and directing victims to adversary-in-the-middle phishing pages or device-code authentication flows that yield credentials, session tokens, and OAuth tokens. Post-compromise behavior includes Microsoft Graph enumeration of users, SharePoint, and OAuth grants, plus persistence via attacker-controlled MFA methods. Google Threat Intelligence tracks related activity as UNC6671, linked to the BlackFile, Helix, Falcon, Pink, and Redact extortion gangs.

McKesson copes with fallout from data theft extortion attack

McKesson discloses a data theft extortion attack by ShinyHunters affecting oncology and medical-surgical customers, with a reported $55 million demand.

McKesson disclosed that attackers gained access to some of its third-party applications and stole data associated with a subset of customers in its oncology, multispecialty, and medical-surgical business units; the intrusion ran for four days from August 21 and was discovered August 25. ShinyHunters claimed responsibility and listed McKesson on its data-leak site, reportedly demanding more than $55 million with a September 1 deadline. Flashpoint analysts say the group typically uses social engineering and identity weaknesses with valid credentials to access cloud-hosted environments, making the intrusion hard to detect. McKesson, which distributes about one-third of pharmaceuticals used in North America with $403.4 billion in annual revenue, says operations continue and it has reasonable assurance of no ongoing unauthorized activity.

ShinyHunters claims Florida DMV breach, puts data on the clock

ShinyHunters claims it breached Florida DMV's DAVID database, stole 200,000+ driver records including SSNs, and set a September 11 extortion deadline.

The ShinyHunters extortion group claims it breached the Florida Department of Highway Safety and Motor Vehicles' DAVID driver and vehicle database and stole more than 200,000 records. As evidence it published a screenshot of a Jeffrey Epstein record showing address, Social Security number, date of birth, license number and registered vehicles, and set a September 11 deadline before publication. The group says it obtained access through a password-reset weakness, compromised employee accounts, and queried and downloaded driver records and images. The Florida DMV has not confirmed the claim; it follows a separate confirmed IDScan.net breach exposing over 153 million license scans that prompted an FBI investigation.
