Classified files apparently leaked from a cyber unit of the Iranian government show that Iran is looking to improve its offensive cyber capabilities, including for targeting industrial control systems. British news outlet Sky News managed to obtain five internal reports - all marked "Very confidential" - that seem to originate from the Islamic Revolutionary Guard Corps' Shahid Kaveh, a secret offensive cyber unit.

WireGuard, a high performance and easily configured VPN protocol, is getting a native port from Linux to the Windows kernel, and the code has been published as experimental work in progress. A WireGuard implementation for Windows already exists and can be found here, based on what Jason A Donenfeld, the creator of WireGuard, called "a generic TUN driver we developed called Wintun" and a cross-platform Go codebase called wireguard-go.

Saudi Arabia's state oil giant acknowledged Wednesday that leaked data from the company - files now apparently being used in a cyber-extortion attempt involving a $50 million ransom demand - likely came from one of its contractors.

Israeli-based NSO Group is being blasted in a groundbreaking report that alleges that the company's controversial Pegasus malware is being used to target activists, journalists, business executives and politicians on a widespread level, using a variety of exploits - including a zero-click zero-day in iOS.

CVE-2021-1675, a Windows Print Spooler vulnerability that Microsoft patched in June 2021, presents a much greater danger than initially thought: researchers have proved that it can be exploited to achieve remote code execution and - what's worse - PoC exploits have since been leaked. The Windows Print Spooler is an application / interface / service that interacts with local or networked printers and manages the printing process.
