OffSeq Mirage honeypot sensors detected a malicious file with SHA-256 hash 3b4a276caa4501514e1da534b1d744ca7766c6d942fdd66a56ec71e941960f4f on 2026-07-09, observed twice in attacker activity. The attack technique involved is T1105 (Ingress Tool Transfer), which typically involves transferring tools or payloads into a target environment. The file hash fingerprints a specific malicious payload that could be a dropper, web shell, miner, or post-exploitation tool. The attacker infrastructure was located in the United States. There is no indication of a vulnerability or exploit targeting specific software versions, and no known exploits in the wild are reported. This is an indicator of compromise to be used for detection and response.

The presence of this malicious file hash indicates potential compromise involving the transfer of malicious tools or payloads into a target environment. The payload could facilitate further malicious activities such as dropping additional malware, establishing persistence via web shells, mining cryptocurrency, or post-exploitation actions. However, no direct vulnerability or exploit is described, and no known active exploitation campaigns are reported. The impact is primarily detection of attacker activity and potential infection if the file is present in an environment.

No official patch or fix is applicable as this is an indicator of compromise rather than a software vulnerability. Organizations should use this SHA-256 hash to scan their environments, including endpoint detection and response (EDR) and antivirus (AV) systems, as well as threat intelligence feeds, to identify and remediate any presence of this malicious file. Monitoring for T1105 technique activity and blocking ingress tool transfers where possible can reduce risk. Since no patch or vendor advisory is provided, patch status is not applicable.
