Description: udevd in udev 232, when the Linux kernel 4.8.0 is used, does not properly verify the source of a Netlink message, which allows local users to execute arbitrary commands by leveraging access to the NETLINK_KOBJECT_UEVENT family, and the presence of the /lib/udev/rules.d/50-udev-default.rules file, to provide a crafted REMOVE_CMD value. Impact: Local attackers may exploit this issue to execute arbitrary commands with elevated privileges. Mitigation:...

Having little to no coding experience is no longer a problem for wannabe mobile malware authors, thanks to Trojan Development Kits (TDKs). Criminals can now install an app that will allow them to quickly and easily create Android ransomware with their own devices. It should be noted that the use of TDKs is different from malware being created using the Android integrated development environment (AIDE)....

Recently, we discussed how cyber criminals are using the popular voice/chat client Discord to steal cookies from the running Roblox process on a Windows PC. Since then, we’ve noticed another attack going after the same information, only this time it is via Chrome extensions (CRX files). While currently it is targeting only Roblox users, the same technique can be used to steal cookies from any website. The...
