ATTACKS & VULNERABILITIES

TLDR InfoSec

MISCONFIGURED HMIS EXPOSE US WATER SYSTEM TO ANYONE WITH A BROWSER

While conducting a routine scan of industrial-control hosts, Censys researchers discovered an uncommon TLS certificate configuration that led to the discovery of a browser-based HMI platform. These internet-exposed platforms could be used to view and control water systems without authentication. Censys sent a bulk notification to the EPA, and the number of systems that were either read-only or fully controllable was reduced from 300 to 20.

OPEN-SOURCE TOOLKIT OF AN IVANTI CSA ATTACKER

In late 2024, Ivanti released advisories for vulnerabilities in its Cloud Services Appliance (CSA) product, which were discovered to be part of an exploit chain against the products. In this post, Synacktiv researchers break down three of the open-source tools they observed used by attackers in post-exploitation activities on these devices and provide YARA rules to detect them. The attacker planted Suo5 after the initial compromise as a webshell to be used on an internet-facing Exchange server. The attacker then established persistence using the iox tunnel and attempted lateral movement using atexec.py to gain remote code execution via Task Scheduler.
