OffSeq Mirage honeypot sensors detected a malicious file with SHA-256 hash 85a17fe8e290a224a717445d0f5e819283567101a92945ea10069946dc7e19d8 during attacker activity on 2026-07-09. The observed technique was T1105 (Ingress Tool Transfer), which 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 Great Britain. No CVE or patch information is associated with this indicator, and no known exploits in the wild have been reported. This is an indicator of compromise (IOC) useful for detection and blocking.

The presence of this malicious file indicates potential compromise involving the transfer and execution of harmful payloads such as droppers, web shells, miners, or post-exploitation tools. This can lead to unauthorized access, persistence, data theft, or resource abuse. However, no specific exploit or vulnerability is described, and no known active exploitation has been reported.

No patch or official fix is applicable as this is an indicator of compromise rather than a vulnerability. Organizations should match the provided SHA-256 hash against files in their environment using EDR, antivirus, and threat intelligence tools to detect and remove this malicious payload. Monitoring for T1105 technique activity and blocking related attacker infrastructure IPs may also help reduce risk.
