Fake Adobe update installing malicious cryptomining malware

Fake Flash updates that push malware have traditionally been easy to spot and avoid, however a new campaign has employed new tricks that download cryptocurrency miners in "stealth" mode on Windows systems. 

The recently discovered campaigns have been active since August, appear to be legitimate, however, they act as Flash updates using standard pop-up notifications from the official Adobe installer, and even actually updating a victim’s Flash Player to the latest version. 

Victims who believe the legitimate Flash update has loaded a "XMRig" cryptocurrency miner is stealthily downloaded and runs in the background of the infected Windows computers.
