The OffSeq Mirage threat intelligence platform observed the URL http://server/re.sh being used by attackers on 2026-06-25. This URL is linked to the MITRE ATT&CK technique T1105, which involves ingress tool transfer, suggesting the URL is used to download attacker tools or enable callbacks during attacks. The activity was observed three times from attacker infrastructure located in Poland. There are no associated software vulnerabilities or affected product versions. No known exploits in the wild have been reported for this indicator. The URL serves as an indicator of compromise rather than a direct vulnerability.

Allowing communication with the URL http://server/re.sh could enable attackers to transfer malicious tools or commands, potentially facilitating further compromise of affected systems. However, no direct exploit or vulnerability is described, and no known active exploitation has been reported.

Block access to the URL http://server/re.sh at network perimeter controls such as proxies, web filters, or web application firewalls (WAFs). Monitor proxy, web, and WAF logs for any requests to this URL to detect potential attacker activity. Since this is an indicator of compromise and not a vulnerability, no patch or software update is applicable. Follow standard incident response procedures if traffic to this URL is detected.
