DHS Thinks Some SCADA Problems Are Too Big To Call “Bug”

The Stuxnet worm may be the most famous piece of malicious software ever written. When it was first detected, a little over a year ago, the worm sounded a warning to nations around the world that critical infrastructure systems were potential targets of attack for foreign governments and cyber criminal organizations alike. But with the anniversary of the Stuxnet worm’s discovery just past, the Department of Homeland Security admits that it is now reevaluating whether it makes sense to warn the public about all of the security failings of industrial control system (ICS) and SCADA software. 

Researcher Says Siemens Downplaying Serious SCADA Holes

Dillon Beresford, the NSS Labs researcher who disclosed serious holes in industrial control system software from Siemens says the company is downplaying the seriousness of the vulnerabilities in its public statements, and that a supposed “fix” for the vulnerabilities is inadequate. 

UPDATE: A week after a security researcher decided to cancel a technical discussion of security holes in industrial control software from Siemens, Inc., public exploits for the vulnerabilities are on hold while the company works to shore up systems running its Simatic programmable logic controller (PLC) software.
