In addition to ditching Windows 7, the agency urged network defenders to lock down TeamViewer desktop-sharing software and ensure proper password hygiene and rules are employed.
Update to the latest version of the operating system (e.g.The joint-advisory contains specific mitigation recommendations to harden ICS/SCADA networks across the country. Sodium hydroxide, also known as lye, controls the acidity in potable water but elevated levels maliciously added to water supply can cause physical harm to the public. Local law enforcement officials said an unknown adversary hacked into the plant remotely and attempted to elevate levels of levels of sodium hydroxide by a factor of more than 100.
“The cyber actors likely accessed the system by exploiting cybersecurity weaknesses, including poor password security, and an outdated operating system,” the agency said, repeating urgent warnings that these present a perfect playbook and roadmap into sensitive networks.Īs SecurityWeek previously reported, the hack was spotted on February 5th - and neutralized - in real time by staff at the plant that supplies water to Oldsmar, a small city close to Tampa, Florida. In its bulletin, the agency all but confirmed public reports that the TeamViewer software was used to gain unauthorized access to the system. Cyber actors often use misconfigured or improperly secured RDP access controls to conduct cyberattacks.” “Since the end of July 2019, malicious RDP activity has increased with the development of a working commercial exploit for the vulnerability. Cyber actors continue to find entry points into legacy Windows operating systems and leverage Remote Desktop Protocol (RDP) exploits,” the agency warned.

“Continued use of Windows 7 increases the risk of cyber actor exploitation of a computer system. More ominously, Microsoft will only offer the ESU plan until January 2023, meaning that any tardy organization lagging with OS migration plans will be sitting duck for dangerous hacker attacks. The ESU is a per-device plan available for Windows 7 Professional and Enterprise versions, with an increasing price the longer a customer continues use.

This means that unless organizations purchase an Extended Security Update (ESU) plan from Microsoft, security patches for remote, code-execution vulnerabilities will remain unpatched. Microsoft ended support for Windows 7 more than a year ago but, as cybersecurity experts warn on a nonstop basis, the plants and factories that run critical infrastructure are very slow to migrate to newer operating systems. In addition to running Windows 7 on computers at the plant, all devices used the same password for remote access.
The government’s latest appeal, issued via a joint advisory from the Cybersecurity and Infrastructure Security Agency (CISA), comes amidst reports that the remote hack of the water plant near Tampa Bay was being blamed on poor password hygiene and attacks on systems running Microsoft’s out-of-service Windows 7 operating system. government’s cybersecurity agency is pleading with critical infrastructure defenders to rip-and-replace Windows 7 from their networks as a matter of urgency. On the heels of last week’s lye-poisoning attack against a small water plant in Florida, the U.S.
