The file BetPulseCommand.exe (SHA-256: b1c6ec7ee5dc0f95610f30e9212964877d2aef4995ad64a2fb41fb8d7f0c1453, size: 3.13 MB) is confirmed as malicious based on VirusTotal scan results, where 49 out of 71 security vendors flag the sample as malware. VirusTotal assigns the popular threat label “trojan.msil/quasar”, and multiple independent engines explicitly detect it as Backdoor.Quasar, MSIL/Quasar, or QuasarRAT, including detections from Microsoft, ESET, Kaspersky, GData, Avast, Sophos, TrendMicro, and Malwarebytes. The file is identified by VirusTotal as a .NET (MSIL) PE executable, and the high multi-vendor detection consensus alone provides sufficient technical evidence that this sample is a QuasarRAT remote access trojan, without relying on external analysis beyond VirusTotal.
