Quote:The GandCrab v5 ransomware has started to use the recently disclosed Task Scheduler ALPC vulnerability to gain System privileges on an infected computer. This vulnerability was recently patched by Microsoft in the September 2018 Patch Tuesday, but as shown by computers still vulnerable to EternalBlue, business can be slow to install these updates.
The Task Scheduler ALPC vulnerability is a 0day exploit that was revealed by a security researcher on Twitter. When used, the vulnerability will allow executables to be executed using System privileges, which allows commands to be executed with full administrative privileges.
GandCrab's use of this vulnerability was first discovered by a malware analyst named Valthek, who posted about it on Twitter. Valthek has told BleepingComputer that this vulnerability appears to be the same one that security researcher Kevin Beaumont posted in his Github repository.
