WHITECOBRA FLOODS VSCODE MARKET WITH CRYPTO-STEALING EXTENSIONS

A threat actor named WhiteCobra has been flooding the VSCode marketplace and OpenVSX registry with malicious extensions targeting VSCode, Cursor, and Windsurf users. The extensions contain an extension.js file that is nearly identical to the Hello World example but loads a prompt.js file, which downloads and executes a platform-specific infostealer payload from Cloudflare Pages. An Ethereum core developer reported on X that their wallet was drained after downloading a seemingly legitimate extension with a professional logo, detailed description, and 54K downloads.

THE CURIOUS TALE OF A FAKE CARRIER.APP

Google Project Zero found a fake carrier app exploiting a heap overflow in Apple's DCP firmware on iPhone 12/13. The exploit bypassed kernel protections by targeting the DCP's weaker security, using a fake Vodafone app distributed via enterprise certificates to sideload malware. The vulnerability (CVE-2021-30983) caused memory corruption through an unbounded loop in display code, allowing attackers to gain kernel access by corrupting C++ objects and manipulating memory between the DCP and main system.

UNMASKING THE GENTLEMEN RANSOMWARE: TACTICS, TECHNIQUES, AND PROCEDURES REVEALED

The leak reveals that the Great Firewall operates as a commercial platform called "Tiangou," which has been exported to Myanmar, Pakistan, Ethiopia, Kazakhstan, and other Belt and Road countries for surveillance purposes. The 500 GB archive includes source code, project records, and internal documents revealing how China's censorship functions and spreads globally through public-private partnerships.
