OffSeq Mirage honeypot sensors detected the SHA-256 hash dc57f496cc489f275bb58e36d47c760794a0da5532ad13655b761ff79f7651a1 four times during attacker activity from July 7 to July 8, 2026. The file is linked to the T1105 technique (Ingress Tool Transfer), which involves transferring tools or payloads into a target environment. The malicious payload could be a dropper, web shell, miner, or post-exploitation tool, but no further technical details or exploit mechanisms are provided. The attacker infrastructure was identified in Great Britain. There are no known exploits in the wild or vendor patches related to this indicator. This is an intelligence indicator to support detection and response efforts.

The presence of this malicious file hash indicates potential compromise involving the transfer of malicious tools or payloads into a target environment. The exact impact depends on the payload type (dropper, web shell, miner, or post-exploitation tool), but no specific exploitation or damage details are provided. No known active exploitation has been reported.

No official patch or remediation is available or applicable as this is an indicator of compromise rather than a vulnerability. Security teams should match this SHA-256 hash against files in their environments, endpoint detection and response (EDR) systems, antivirus (AV) solutions, and threat intelligence feeds to detect potential presence. Investigate any matches promptly to determine if malicious activity has occurred. Follow standard incident response procedures if the file is found.
