Microsoft’s beefed-up take on Linux server security has hit general availability
www.theregister.com/2021/01/12/microsoft_linux_edr/ After a few months in preview, Microsoft has made Defender Endpoint Detection and Response (EDR) generally available for Linux servers. Microsoft has extended its Defender product over multiple platforms throughout the last year or so, having shaved the “Windows” prefix from the system. Android, macOS, and iOS have all joined the party and Microsoft Defender for Endpoint turned up for Linux around six months ago. The theory goes that administrators with a mixed network can onboard devices via the same portal and view alerts in what Microsoft describes as a “single pane of glass experience”. Also:

Operation Spalax: Targeted malware attacks in Colombia
www.welivesecurity.com/2021/01/12/operation-spalax-targeted-malware-attacks-colombia/ In 2020 ESET saw several attacks targeting Colombian entities exclusively. These attacks are still ongoing at the time of writing and are focused on both government institutions and private companies. For the latter, the most targeted sectors are energy and metallurgical. The attackers rely on the use of remote access trojans, most likely to spy on their victims. They have a large network infrastructure for command and control: ESET observed at least 24 different IP addresses in use in the second half of 2020. These are probably compromised devices that act as proxies for their C&C servers.
