Sample SHA-256: 88f20e70c092cf96d04211015985c6e89eec8856839463f6c46acac669ded043 shows strong malicious consensus on VirusTotal (51/72 detections). Vendors primarily classify it as an MSIL AsyncRAT/DcRAT backdoor. In addition to static detections, sandbox analysis flags the file as a RAT with evasion behavior, and multiple Sigma rules indicate scheduled task creation for persistence via schtasks.exe, which is commonly associated with AsyncRAT deployments. These combined indicators confirm the sample as a verified malware specimen suitable for MalwareBazaar sharing
