Detects evidence of an argument-injection attack against MikroTik RouterOS (CVE-2026-86060), where the attacker provides the literal username '-2' during the login process. This action allows the attacker to bypass standard credential validation by exploiting a forged privilege mask. This is typically observed in conjunction with unauthorized access attempts following CVE-2026-67279.
Detects the creation of an administrative-level user account (e.g., 'ops') on a MikroTik RouterOS device shortly after an anomalous login attempt using the '-2' username. This sequence is indicative of the exploit chain associated with specific MikroTik RouterOS vulnerabilities where an unauthenticated or specially crafted login is used to facilitate unauthorized user creation.
Detects the creation of a new local user account named 'ops' or an account with 'full' group privileges on MikroTik RouterOS. This rule is designed to identify potential persistence mechanisms following the exploitation of MikroTrick vulnerabilities (CVE-2026-67279/CVE-2026-86060), often indicated by anomalous prior login patterns.
Detects the presence of an unauthorized administrative account (e.g., 'ops') on MikroTik RouterOS devices following a system 'Flagged' indicator. This rule correlates administrative account creation or modification events with system-reported compromise indicators to identify post-exploitation persistence mechanisms related to known RouterOS vulnerabilities.
This rule detects potential attempts to exploit an SSH pre-authentication rekey or authentication bypass vulnerability (CVE-2026-67279) in MikroTik RouterOS devices. It monitors incoming TCP traffic on port 22 that contains the 'ROSSSH' signature followed by specific binary sequences indicative of exploitation attempts.
