Another day, another ransomware gang. The Dark Power ransomware gang is new on the block, and is trying to make a name for itself. This blog dives into the specifics of the ransomware used by the gang, as well as some information regarding their victim naming and shaming website, filled with non-paying victims and stolen data.
Trellix Advanced Research Center stumbled across a vulnerability in Python’s tarfile module. As we dug into the issue, we realized this was in fact CVE-2007-4559. The vulnerability is a path traversal attack in the extract and extractall functions in the tarfile module that allow an attacker to overwrite arbitrary files by adding the “..” sequence to filenames in a TAR archive. Over the course of our research into the impact of this vulnerability we discovered that hundreds of thousands of repositories were vulnerable to this vulnerability. While the vulnerability was originally only marked as a 6.8, we were able to confirm that in most cases an attacker can gain code execution from the file write.
