Chinese Hackers Exposed by U.S. Water Control System Decoy

August 5, 2013

A notorious hacking group from China, known as APT1 or Comment Crew, potentially affiliated with the Chinese military, has been caught infiltrating a simulated United States water control system, also referred to as a honeypot. Kyle Wilhoit, a researcher from Trend Micro, disclosed the findings at the BlackHat Conference this past Wednesday.

Back in December, the hackers targeted a water control system for a U.S. municipality, unaware it was a ruse set up by Wilhoit. The decoy utilized a Word document embedded with malicious software, allowing for complete access.

These honeypots closely resembled the ICS/SCADA devices employed in critical infrastructure for power and water facilities. The setup, which employed cloud software, produced realistic web-based login and configuration screens for local water plants, making them look as though they were based in various countries, including Ireland, Russia, Singapore, China, Japan, Australia, Brazil, and the U.S. Researchers have traced the activity back to the APT1 Group, which was previously linked to by the security firm Mandiant.

September 5, 2025
Vulnerability / Threat Intelligence

Federal Civilian Executive Branch (FCEB) agencies are directed to update their Sitecore systems by September 25, 2025, due to a critical security vulnerability, identified as CVE-2025-53690, that is currently being exploited. The vulnerability has a CVSS score of 9.0 out of 10, highlighting its severity. According to the U.S. Cybersecurity and Infrastructure Security Agency (CISA), this flaw affects Sitecore Experience Manager (XM), Experience Platform (XP), Experience Commerce (XC), and Managed Cloud, allowing for deserialization of untrusted data through default machine keys. This presents an opportunity for attackers to execute remote code by exploiting exposed ASP.NET machine keys. Mandiant, a Google-owned cybersecurity firm, reported that the ongoing ViewState deserialization attacks utilized a sample machine key found in Sitecore deployment guides from 2017 and earlier. The threat intelligence team…

Supply Chain Attack / API Security

Salesloft has announced that the breach associated with its Drift application originated from a compromised GitHub account. An investigation by Google-owned Mandiant revealed that the threat actor, identified as UNC6395, accessed the Salesloft GitHub account over a span of three months, from March to June 2025. The method of access to the GitHub account remains unknown. Currently, 22 companies have reported being impacted by this supply chain breach. According to Salesloft’s advisory, the attackers leveraged this access to download content from various repositories, add a guest user, and establish workflows. The investigation also revealed that reconnaissance activities were taking place within the Salesloft and Drift application environments during the same time frame. However, it noted that there is no indication of any actions beyond these limited reconnaissance efforts. In the subsequent phase, the attackers gained access to Drift’s Amazon Web Services (AWS)…
