Siemens Warns of Industrial Virus
Category : General 19 Jul 2010 01:54 AM | Industry News
Stuxnet is among the first to surface that attacks software programs that run Supervisory Control and Data Acquisition, or SCADA, systems. Such systems are used to monitor automated plants -- from food and chemical facilities to power generators.
Once the worm infects a Siemens system, it quickly sets up communications with a remote server computer that can be used to steal proprietary corporate data or take control of the SCADA system, said Randy Abrams, a researcher with ESET, a privately held security firm that has studied Stuxnet.
Analysts said attackers may have chosen to spread the malicious software via a thumb drive because many SCADA systems are not connected to the Internet, but do sport USB ports.
The highly sophisticated worm also takes advantage of default passwords used by Siemens' management consoles to connect and then try to steal industrial secrets from infected companies.
The virus transmits itself through infected USBs. When the USB is plugged in to a computer, the virus copies itself into any other connected USBs and, if it recognizes Siemens' software, it tries to log in to the computer using a default password.
