- →Exploit targets the XML-RPC interface of SonicWall GMS; inspect HTTP request bodies destined to the GMS appliance for the string 'set_time_' followed by the byte sequence 0x22 0x60 (quote + backtick), which is indicative of shell command injection via the set_time_zone XML-RPC method. ↗
- →Traffic pattern is inbound from external networks to internal servers (to_server, established), targeting the GMS virtual appliance's XML-RPC endpoint; focus monitoring on datacenter-hosted GMS instances. ↗
- →MITRE ATT&CK mapping is Lateral Movement (TA0008) / Exploitation of Remote Services (T1210); correlate with post-exploitation lateral movement activity if the GMS appliance is compromised. ↗
- ·The vulnerability affects SonicWall GMS version 8.1 and earlier only; ensure detection rules are scoped to environments running these versions to reduce false positives. ↗
- ·The Snort/ET rule (sid:2026023) is recommended for Datacenter deployment contexts per its metadata; deploying it broadly in non-datacenter environments may require tuning. ↗

Executive Summary:
Unit 42 has uncovered new variants of the well-known IoT botnets Mirai and Gafgyt. These are the IoT botnets associated with unprecedented Distributed Denial of Service attacks in November 2016 and since.
These variants are notable for two reasons:
The new Mirai version targets the same Apache Struts vulnerability associated with the Equifax data breach in 2017.

Executive Summary:
Unit 42 has uncovered new variants of the well-known IoT botnets Mirai and Gafgyt. These are the IoT botnets associated with unprecedented Distributed Denial of Service attacks in November 2016 and since.
These variants are notable for two reasons:
- The new Mirai version targets the same Apache Struts vulnerability associated with the Equifax data breach in 2017.
- The new Gafgyt version targets a newly disclosed vulnerability affecting older, unsupported versions of SonicWall’s Global Management System (GMS).
These developments suggest these IOT botnets are increasingly targeting enterprise devices with outdated versions.
All organizations should ensure they keep not only their systems up-to-date and patched, but also their IoT devices. For Palo Alto Networks cust
