Aggah

The Aggah malware is a variant of the Revenge RAT (Remote Access Trojan) that has been used in massive attacks in the Middle East. Computer security researchers discovered that a previously unknown group made changes to the original RevengeRAT source-code and used the alias 'haggah' in attacks. The threat actors use spam emails to distribute their RAT and may use emails that look like internal company messages. The attackers appear to use filenames similar to commonly used names for work documents and lure users into downloading a macro-enabled Microsoft Word document.

The Aggah RAT (Remote Access Trojan) is delivered as a final payload through a series of scripts. A typical Aggah attack involves no less than nine steps and changing Registry values associated with MS Office too. Users who open dropper files linked to the Aggah RAT are shown a warning to enable loading content from remote hosts. That is a trick intended to enable macros and load scripts from a weaponized page on the Blogspot platform. The harmful Blogspot page hosts JavaScripts which are downloaded to the user's PC and executed with admin privileges. The threat actors succeed in disabling the native AV tool on Windows and disable functions in the Microsoft Office suite. Then, the dropper file runs PowerShell commands via a hidden instance of the Windows PowerShell command line tool. The commands install the Aggah RAT to the local disk and register a scheduled task so that the malware is loaded on Windows boot.

The Aggah RAT is a generic remote access tool that enables threat actors to retrieve files from your PC; delete files on your disks; run/terminate programs; pull your Web browser bookmarks and saved passwords; take screenshots of your desktop; access your Webcam and microphone. You should avoid questionable emails and run security scans every week if you wish to diminish the risks of being infected with the Aggah RAT.
