State-backed Chinese hackers have developed a Linux variant for the SideWalk backdoor used against Windows systems belonging to targets in the academic sector. The SideWalk Linux backdoor has been observed in the past, initially being tracked as StageClient by security researchers at cybersecurity company ESET.

September's Patch Tuesday is here and it brings, among other things, fixes from Microsoft for one security bug that miscreants have used to fully take over Windows systems along with details of a second vulnerability that, while not yet under attack, has already been publicly disclosed.
