New Upatre Trojan phishing campaign targets Windows XP
Malware delivered by email with the subject line 'Attorney-client agreement'
AppRiver has uncovered a new Upatre Trojan phishing campaign that specifically targets machines still running Windows XP.
Upatre Trojan can steal personal details and download additional malware, and this newest threat is delivered via an email with the subject line 'Attorney-client agreement'. The content of the email refers to a court case involving the owner of the target computer, who is purportedly involved in a breach of contract.
"One interesting detail about this line of attack is that they seem to be targeting older, out of date PCs," Fred Touchette, senior security analyst of AppRiver said. "After running the samples on a couple of different operating systems, they only seemed to want to carry out their malicious intent on machines running Windows XP (I was using SP3)."
Once up and running, the malware hacks systems processes to infiltrate the computer, checks its IP address and then tries to communicate with the IP 188.8.131.52 on port 12299 and reports back with the information it has uncovered from the computer, such as the IP address and the computer's name.
The malware then adds registry entries, many of which refer to disallowing security certificates and looking for debugging tools to further disarm the target computer.
He explained that if the malware was executed on newer machines, it would be shut down before it has a chance to run, rendering it useless.
Referring to the means of delivery of the malware, Touchette joked: "This must come as a real shock to those of us who don't keep a lawyer on retainer and those who didn't realise they were being sued. It probably would've been really nice of this mystery lawyer to let you know that this was going on before it got to this point, I would think."
