Malware with Community on the Dark Web
October 14, 2016
While Mac malware is perhaps less common than attacks designed for PC, it is not entirely absent. The Register covers this in a recent article, EasyDoc malware adds Tor backdoor to Macs for botnet control. The malware is disguised as a software application called EasyDoc Converter which is supposed to be a file converter but does not actually perform that function. Instead, it allows hackers to control the hacked mac via Tor. The details of the software are explained as follows,
The malware, dubbed Backdoor.MAC.Eleanor, sets up a hidden Tor service and PHP-capable web server on the infected computer, generating a .onion domain that the attacker can use to connect to the Mac and control it. Once installed, the malware grants full access to the file system and can run scripts given to it by its masters. Eleanor’s controllers also uses the open-source tool wacaw to take control of the infected computer’s camera. That would allow them to not only spy on the victim but also take photographs of them, opening up the possibility of blackmail.
A Computer World article on EasyDoc expands on an additional aspect of this enabled by the Dark Web. Namely, there is a Pastebin agent which takes the infected system’s .onion URL, encrypts it with an RSA public key and posts it on Pastebin where attackers can find it and use it. This certainly seems to point to the strengthening of hacking culture and community, as counterintuitive of a form of community, it may be to those on the outside.
