The Fareit malware was discovered in 2012 and has been undergoing evolution to bypass antivirus detection. It is now one of the most successful information stealers deployed in malspam campaigns. The source code of the malware has been leaked on the Internet which enabled any malware author to use it in their attack campaigns.
