Password-Stealing Malware Exposes 1,787 US Water Providers
New research from cybersecurity firm SpyCloud reveals that over a thousand U.S. water and wastewater providers are at risk due to password-stealing malware that compromised employee credentials and session tokens. The firm analyzed over 66,000 public-facing systems registered with the Environmental Protection Agency, identifying 1,787 organizations (nearly 20%) with stolen credentials, and at least 250 with credentials having potential access to operational networks. A case study of an unnamed metering tech provider found one infected device had leaked passwords for 167 utility companies. While this research did not link these exposures to the recent Iran-backed hacks, it underscores the vulnerability of critical infrastructure through infostealer malware and the trade of stolen credentials.

CISA: Hackers Hit 100+ U.S. Water Systems in July
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) reported that more than 100 internet-exposed systems in the U.S. water and wastewater sector were targeted by cyberattacks in July. The attacks largely targeted programmable logic controllers (PLCs) from multiple manufacturers — including Rockwell, Schneider Electric, and Siemens — and relied in part on AI tools to produce scripts capable of exploiting vulnerable PLCs. While the intrusions have caused outages and disruptions during investigations, they have had little effect on water supplies. U.S. officials say intelligence points to Iran as the likely actor but have not made a definitive attribution. The incidents raise broader concerns about the cybersecurity and resilience of U.S. critical infrastructure.
US warns AI-aided hackers target Siemens S7 water systems
U.S. security agencies including CISA, the FBI and the NSA issued an advisory saying hackers are actively exploiting Siemens S7 programmable logic controllers (PLCs) used in critical infrastructure. The agencies warned attackers are using AI to generate exploit scripts that leverage publicly available information to find and compromise out-of-date or poorly secured PLCs, with water supply and wastewater systems across multiple U.S. states already affected. CISA reiterated long-standing guidance to keep such devices disconnected from the internet and cautioned rural communities are often more vulnerable. The advisory follows a series of recent intrusions attributed to suspected Iranian-linked actors targeting U.S. water and energy providers.
124M Passwords Stolen in Stealer-Logs
HaveIBeenPwned has added a dataset containing 124 million stolen passwords and 56 million email addresses to its breach directory. According to the service, the credentials were harvested from infected end-user machines and aggregated in so‑called stealer‑logs created by infostealer malware, rather than leaked from a single major online provider. HaveIBeenPwned did not disclose how it obtained the dataset or whether the records are already circulating on darknet markets. The site allows users to search both email addresses and passwords to check for exposure; registration unlocks additional history and alerting features. Security best practices remain the same: immediately change exposed passwords and avoid reusing them across services.
