Talos blogged about Crypt0l0cker malware in March. First, the Function Identification and Recovery Signature Tool, was released by Talos in December 2016. First was able to port analysis from the unpacking dll to the payload file instantly. First also ported analysis back to a suspected previous version of the sample. The sample is clearly malicious, but my VirusTotal inspection does not suggest that the sample belongs to any known family. No detections refer to Crypt0L0cker, TorrentLocker, nor Teerac.”]
