Detection & IOCsextracted from sources · hover to see the quote
- →Detect POST requests to /op5config/welcome over HTTPS (port 443) containing backtick-wrapped shell metacharacters in the 'password' parameter, indicative of command injection attempts. ↗
- →Look for the specific POST body pattern 'do=do=Login&password=`...`' — the double 'do=do=Login' is a fingerprint of the Metasploit exploit module for this CVE. ↗
- →A timing-based detection heuristic: if a POST to /op5config/welcome takes >= 5 seconds to respond, the exploit module treats the target as vulnerable (timing side-channel via 'ping -c 10 127.0.0.1'). ↗
- →The exploit requires the payload to avoid the bad characters: backtick (`), backslash (\), and pipe (|). Signatures should still flag these characters in the password field as they are the injection delimiters. ↗
- →Payload delivery is via cmd-type payloads (perl, ruby, or python reverse shells) injected into the password parameter — monitor for outbound connections from the op5 host process following a POST to /op5config/welcome. ↗
- ·The exploit communicates exclusively over HTTPS (not HTTP); plain-text HTTP inspection will miss this attack. TLS inspection must be enabled on network sensors to detect the malicious POST body. ↗
- ·The Metasploit module sets 'Connection: close' on every request; persistent/keep-alive session tracking will not help correlate check and exploit requests from the same attacker. ↗
- ·Affected versions are OP5 Monitor 5.3.5, 5.4.0, 5.4.2, 5.5.0, 5.5.1 and op5 Appliance before 5.5.3 / system-op5config before 2.0.3. Detections should be scoped to these versions to reduce false positives. ↗

Since the discovery of the Mirai variant using the binary name ECHOBOT in May 2019, it has resurfaced from time to time, using new infrastructure, and more remarkably, adding to the list of vulnerabilities it scans for, as a means to increase its attack surface with each evolution.
Unlike other Mirai variants, this particular variant stands out for the sheer number of exploits it incorporates, with the latest version having a total of 71 unique exploits, 13 of which haven’t been seen exploited in the wild until now, ranging from extremely old CVEs from as long back as 2003, to recent vulnerabilities made public as recently as early December 2019. Based on this seemingly odd choice, one could risk a guess that the attackers could potentially be aiming for the sweet sp
