Once again, we have seen a significant new ransomware family in the news. LockerGoga, which adds new features to the tried and true formula of encrypting victims’ files and asking for payment to decrypt them, has gained notoriety for the targets it has affected.
LockerGoga is a ransomware that exhibits some interesting behaviors we want to highlight. Based on our research, and compared with other families, it has a few unique functions and capabilities that are rare compared to other ransomware families that have similar objectives and/or targeted sectors in their campaigns.
In order to uncover its capabilities, we analyzed all the samples we found, discovering similarities between them, as well as how the development lifecycle adds or modifies different features in the code to evolve the ransomware in a more professional tool used by the group behind it.
