Compressed archive created by bzip2, a file compression program often found on Unix-based systems; incorporates the Burrows-Wheeler compression algorithm as well as Run-Length Encoding (RLE) for high levels of compression; often used for Linux software package distributions. Same could be opened on Windows machines via compression software like Winrar, 7-Zip etc., These archive file types can contain malicious files.
After validating business usage, monitor & block the download and execution of bz2 archive files on email & web gateways and endpoints . Whitelist as required.
