Sophisticated malicious software which infects critical infrastructure systems is spreading in the wild, according to security companies.
Finnish security company F-Secure, which is in the process of analyzing the malware, told ZDNet UK that critical infrastructure in India and Iran had been affected.
The malware takes advantage of a zero-day vulnerability in Microsoft .lnk shortcut files, and infects Siemens WinCC Scada software running on Windows 7 Enterprise Edition x86 systems. It spreads via USB drives and runs automatically when a shortcut icon is displayed on a user's screen.
