Google backpedals on new Android developer registration rules
Google is backpedaling on its decision to introduce new identity verification rules for all developers, stating that it will also introduce accounts for limited app distribution and will allow users to install apps from unverified devs.

The new rules require that all apps must originate from developers with verified identities to be installed on certified Android devices; otherwise, their installation will be blocked.
Anthropic claims of Claude AI-automated cyberattacks met with doubt
Anthropic reports that a Chinese state-sponsored threat group, tracked as GTG-1002, carried out a cyber-espionage operation that was largely automated through the abuse of the company’s Claude Code AI model.

Kraken ransomware benchmarks systems for optimal encryption choice
The Kraken ransomware, which targets Windows, Linux/VMware ESXi systems, is testing machines to check how fast it can encrypt data without overloading them.
According to Cisco Talos researchers, Kraken’s feature is a rare capability that uses temporary files to choose between full and partial data encryption.
The Kraken ransomware emerged at the begining of the year as a continuation of the HelloKitty operation, and engages in big-game hunting attacks with data theft for double extortion.

Although the packages do not have a malicious component for developers (e.g., stealing data, backdooring hosts), this could change with an update that introduces a dangerous payload.
