Espionage attacks using cyber weapons are usually associated with the stealing of data and intellectual property. The attack that it the subject of this paper reminds us of a forgone espionage technique – wiretapping.
While most research labs nowadays are tuned to uncover info-stealing attacks, identified by a malware capable of exfiltrating sensitive data such as quarterly reports and credentials, we were able to uncover a threat actor who is after our business calls.
The attack targets one of the biggest pieces of open-source software that operates on PBX (Private Exchange Branch) servers, called Asterisk. With 2M downloads per year, Asterisk is one of the most popular VoIP PBX free programs used by industries and companies worldwide to manage and distribute internal phone extensions and calls between telecommunication endpoints.
The infection vector is a customized PHP WebShell, which is weaponized with new techniques targeting the Asterisk internal configuration files and databases - the same databases that hold all of the calls' metadata as well as the recordings of the calls.
And here is dissonance: while PHP WebShell is not the most sophisticated technique, and the victims' characteristics are largely civilian, wiretapping is something that is usually coupled with nation-state attacks.
In our presentation we will try to shade more light on the business model and the threat actor behind this attack. We will address the motive of the attacks, and the techniques used to make this attack a success. Of course, we will also share with the audience relevant TTPs and IoCs.
