What is GlobeImposter-BIG4+ ransomware? And how does it execute its attack?
GlobeImposter-BIG4+ ransomware, as its name suggests, is a new variant of GlobeImposter ransomware. There’s only a slight difference with this new variant compared to the older ones. One of the noticeable changes in this new strain is the extension used which is .BIG4+ as well as the email addresses used namely, firstname.lastname@example.org and email@example.com.
When it comes to its attack, GlobeImposter-BIG4+ ransomware still uses the same tactic which starts by dropping its malicious payload in the system which will establish a connection between the infected device and a remote Command and Control server where it also downloads additional malicious files that helps it in executing its attack. These malicious files also make alterations in the Windows Registry in order to run on every system boot. Once these changes are applied, the search for files to encrypt began. According to security experts, it may target files with the following extensions:
