When executed, the attached malware program displays a fake "installation error" box while, in fact, it is installing itself as %sysdir%\remote.exe, altering the registry and shutting down shared access and Windows update services. It then tries to connect to either an IRC server named 'jojogirl.3322.org' (channel name #Phantom) or smallphantom.meibu.com, but fails.
"This latest spear phishing attack, where Skype users are being targeted by an email that appears to come from Skype, is the first case that we've seen that specifically mentions Skype," said Maksym Schipka, a senior antivirus researcher at MessageLabs. "It is another clear example of how malware writers are quickly exploiting newly identified security holes, as we saw with the Zotob attack, and now, new releases of popular software applications, in order to try and spread their malicious payloads.
Another interesting development is the usage of the mutex '___--->>>[E-v-i-l_S-e-c-u-r-i-t-y_T-e-a-m]<<<---___' which links the Chinese creator of the IRCbot trojan with a group of Brazilian/Persian hackers who are known to deface Web sites (their homepage is evil.co.sr, which is a Suriname domain).
