Rewterz Threat Advisory – Industrial Control Moxa – IKS & EDS Multiple Vulnerabilities
March 1, 2019Rewterz Threat Advisory – CVE-2017-2302 – Juniper Junos OS RPD Denial of Service Vulnerability
March 4, 2019
Severity: High
Analysis Summary
The HatMan malware, also known as TRITON and TRISIS, affects Triconex Tricon safety controllers by modifying in-memory firmware to add additional programming. The extra functionality allows an attacker to read/modify memory contents and execute arbitrary code on demand through receiving specially-crafted network packets. HatMan consists of two pieces: a PCbased component to communicate with the safety controller and a malicious binary component that is downloaded to the controller. Safety controllers are used in a large number of environments, and the capacity to disable, inhibit, or modify the ability of a process to fail safely could result in physical consequences.
Impact
Arbitrary code execution
System access
Affected Products
Triconex MP3008 main processor modules running firmware versions 10.0–10.4 are vulnerable
