Duqu Attackers Wiped Out C&C Infrastructure After Public Disclosures

Researchers have known for years that virus writers and attackers pay close attention to the analyses researchers do of their work, and it appears that the Duqu authors are no exception. Shortly after the first public reports about Duqu emerged in early autumn, the crew behind Duqu wiped out all of the command-and-control servers that had been in use up to that point, including some that had been used since 2009.

Researchers: Millions of Printers Vulnerable to Attack

Columbia University researchers say tens of millions of printers may have flawed firmware that could allow hackers to remotely set fires, erase code and infiltrate computer networks, according to a report on MSNBC’s Red Tape Chronicles blog today.


The United States Department of Homeland Security cried foul yesterday morning, debunking claims from both the Illinois Statewide Terrorism and Intelligence Center (STIC) and Applied Control Solutions that a water station in Illinois was hacked earlier this month.

A flurry of reports late last week described an attack on an unnamed Springfield, Ill. water treatment facility where the plant’s supervisory control and data acquisition software (SCADA) were compromised by Russian computers.

Siemens said on Tuesday that it is working with the U.S. Department of Homeland Security to investigate a cyber intrusion into a water treatment plant in South Houston, Texas, but couldn’t confirm that a default, three digit password hard coded into an application used to control the company’s SCADA software played a role. 

In an e-mail interview with Threatpost, the hacker who compromised software used to manage water infrastructure for South Houston, Texas, said the district had HMI (human machine interface) software used to manage water and sewage infrastructure accessible to the Internet and used a password that was just three characters long to protect the system, making it easy picking for a remote attack.
