Chinese hackers purported to have attacked U.S. gas pipeline operations


According to a recent Department of Homeland Security (DHS) report, hackers have successfully broken into numerous U.S. gas pipeline operators from December 2011 through June 2012.  The hackers infiltrated 23 gas pipeline companies by sending e-mails that looked to be official but contained viruses or Trojan horses used to break into the computer system. 
The information stolen was in-depth and the DHS feels this intelligence could later be used to sabotage and take down those gas lines.  Of the 23 gas line operators at least ten of them were hit with information extracted.  Another ten gas line operators were broken into, but it is uncertain if anything was obtained and is still under investigation.
The DHS report does not mention China or any Chinese backed group by name, but the independent security firm Mandiant Corporation confirmed the suspicion.  The facts in Mandiant’s detailed report show how they traced recent government hacks back to China.  The intro to the document reads in part,
Our research and observations indicate that the Communist Party of China (CPC) is tasking the Chinese People’s Liberation Army (PLA) to commit systematic cyber espionage and data theft against organizations around the world.
Presently 30% of the U.S. power grid is dependent on natural gas.  This recent intelligence stolen by the Chinese military could, at least in theory, give them an advantage in destroying natural gas compressor stations in different regions around North America, essentially shutting the economy down with the press of an enter key.
A detailed report from the Obama Administration titled, “Administration Strategy on Mitigating The Theft of U.S. Trade Secrets”, published on February 13, 2012, discusses  the need of beefing up the U.S. infrastructure to prevent these types of future attacks.  More importantly the report gives detailed examples of how trade secrets of major companies are being stolen as well. 
During President Barack Obama’s State of the Union Address he iterated the need for the U.S. to catch up on securing its computer network infrastructure. “America must also face the rapidly growing threat from cyber-attacks,” The President said in part.  “… [W]e know foreign countries and companies swipe our corporate secrets. Now our enemies are also seeking the ability to sabotage our power grid, our financial institutions.”

Can hackers control your HP Printer remotely and set it on fire?


MSNBC ran a detailed article on the allegations that hackers could remotely take over HP LaserJet Printers and set it on fire using a predefined set of instructions.
Can hackers control your HP Printer remotely and set it on fire?
Once taken over, sensitive personal information can be stolen, networks can be attacked and set on fire by executing a set commands designed to heat the printer up.
HP responded to MSNBC with a statement that it is evaluating the problem but contended that the claims by Columbia PhD student Ang Sui and Prof. Salvatore Stolfo are highly exaggerated.
The Prof-student duo claims that the printers are accepting software updates without verifying digital signatures and they are able to remote install malicious software onto it.
In a demonstration of the flaw, the researchers demostrated how by giving instructions, they could heat up the printer fuser of a hijacked computer, which is designed to dry the ink once it is applied to paper, ultimately causing it to burn and smoke. In the same demo, a thermal switch shut the printer down before a fire started. But the researchers expressed their apprehension that such things can easily cause real-world damage if not checked immediately.
