Why we think so
3 points against it and 0 in its favour, checked against the scan evidence.
The reasoning behind this verdict
Eight of the 62 antivirus engines that checked it flagged the file, four of them major, converging on the Farfli backdoor family. The archive is has no sandbox or network data, and no researcher rules corroborate the detection.
Four major antivirus engines independently labeled the sample malicious and one of them named the Farfli family. The file is zero days old and has only a single submission, so prevalence and history cannot offset the detections. No sandbox execution, no files it created, and no external-intel hits are available to confirm or refute the verdict. Because major consensus exists, the limited-evidence exception does not apply and the file is treated as malicious.
What We Detected
Four tier-5 engines (Avast, AVG, Avira, F-Secure, Kaspersky) reported the RAR as malicious; Kaspersky explicitly labeled it HEUR:Backdoor.Win32.Farfli.gen. Three additional less reliable engines also flagged it, bringing the total to eight detections out of 75 engines.
Threat Behavior
Farfli is a known backdoor family capable of remote access, credential theft, and command execution. No sandbox trace or contacted-host data is present in this submission, so actual behaviour in the test run cannot be confirmed.
What To Do Now
Do not open or extract the archive. Keep security software enabled and submit the file to your security vendor for further analysis if you need a second opinion.
