OffSeq Mirage honeypot sensors detected a malicious file with SHA-256 hash 6f87e28bf658c79133f37b3f9eea93746ebd6df8beed4156eeaab78670b8a35d during attacker activity on 2026-07-02. The activity involved the MITRE ATT&CK technique T1105 (Ingress Tool Transfer), which is used to transfer 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 identified as being in the United States. There is no information about known exploits in the wild or affected software versions. This is an indicator of compromise (IOC) to be used for detection and response.

The presence of this malicious file indicates that an attacker has staged or delivered a potentially harmful payload within a target environment. The payload could enable further malicious activities such as persistence, data theft, or resource abuse. However, no direct information about exploitation success or widespread impact is provided.

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