Ukraine says cyberattack hit Russian e-commerce giant Wildberries amid drone strikes

Ukraine's HUR intelligence, with the Cyber Corps group, cyberattacked Russian e-commerce giant Wildberries, disrupting payments and customer service to amplify drone strikes.

Ukraine's Main Intelligence Directorate (HUR) claimed a cyberattack, carried out with the Cyber Corps hacker group, disrupted Russia's largest online marketplace, Wildberries, affecting customer service, contact centers, and payment infrastructure. The operation was designed to amplify kinetic drone strikes; Ukraine says seven of the company's 10 largest logistics centers have been knocked out of operation and more than 1.2 million square meters of warehouse space lost. The claims could not be independently verified and Wildberries has not commented. HUR cited the company's role in Russia's logistics network and in financing the war.

Anthropic Says Russian Hackers Used Claude AI to Automate Malware Evasion

Anthropic disrupted Midnight Blizzard campaigns where AI agents automatically rebuilt malware to evade detection, targeting 20+ government and defense organizations.

Anthropic's threat intelligence report documents the Russian state-nexus actor Midnight Blizzard using Claude to automatically monitor, modify, and redeploy malware until it evaded security products. The campaign hit more than 20 organizations, including Ukrainian and European government ministries, defense bodies, embassies, and think tanks, with mailbox theft from two drone component manufacturers and compromise of hotel guest Wi-Fi via DNS hijacking. The report also describes financially motivated groups GTG-50020 and GTG-50021 targeting AI credentials, including a prompt-injection attack on an automated evaluation sandbox that yielded production API keys and attempts to reach a pre-release Claude model across roughly 30 AI companies.
