Yesterday, I posted a quick analysis of a malicious document that exfiltrates data from the compromised computer[1]. Here is another found that also exfiltrate data. The malware is delivered in an ACE archive. This file format remains common in phishing campaigns because the detection rate is lower at email gateways (many of them can’t handle the file format). The archive contains a PE file called ‘Payment Copy.exe’ (SHA256:88a6e2fd417d145b55125338b9f53ed3e16a6b27fae9a3042e187b5aa15d27aa). The payload is unknown on VT at this time.
