∗∗∗ A Detailed Analysis of a New Stealer Called Stealerium ∗∗∗
---------------------------------------------
Stealerium is an open-source stealer available on GitHub. The malware steals information from browsers, cryptocurrency wallets, and applications such as Discord, Pidgin, Outlook, Telegram, Skype, Element, Signal, Tox, Steam, Minecraft, and VPN clients. The binary also gathers data about the infected host, such as the running processes, Desktop and webcam screenshots, Wi-Fi networks, the Windows product key, and the public and private IP address.

∗∗∗ Rustproofing Linux (nccgroup) ∗∗∗
---------------------------------------------
The nccgroup blog is carrying afour-part series by Domen Puncer Kugler on how vulnerabilities can maketheir way into device drivers written in Rust. In other words, the CONFIG_INIT_STACK_ALL_ZERO build option does nothing for Rust code! Developers must be cautious to avoid shooting themselves in the foot when porting a driver from C to Rust, especially if they previously relied on this config option to mitigate this class of vulnerability. It seems that kernel info leaks and KASLR bypasses might be here to stay, at least, for a little while longer.
