OffSeq Mirage honeypot sensors detected a malicious file with SHA-256 hash 1a91f6c9109a1e3c0a7dee758c861869c08ee339283f8150dde01e85c1137128 twice on 2026-07-02. The file is linked to the T1105 technique, indicating it was used for ingress tool transfer during an attack. The malicious payload could be a dropper, web shell, miner, or post-exploitation tool. The attacker infrastructure was identified in the US. This is an indicator of compromise (IOC) useful for detection and response but does not represent a vulnerability or exploit itself. There is no patch or remediation specific to this file hash, and no known exploits in the wild have been reported.

The presence of this malicious file indicates attacker activity involving the transfer of tools or payloads into a target environment. If executed, the payload could facilitate further compromise such as establishing persistence, mining cryptocurrency, or enabling remote control. However, this is an indicator of a malicious file rather than a vulnerability or exploit, so the impact depends on whether the file is present and executed in the environment.

No specific patch or remediation is available or required for this file hash. Organizations should use this SHA-256 hash as an indicator of compromise to detect and block the associated malicious payload in their environments using endpoint detection and response (EDR), antivirus (AV), and threat intelligence feeds. Regularly updating detection signatures and monitoring for this hash can help prevent successful execution of the malicious payload.
