Someone is trying to attack computer networks belonging to U.S. natural-gas-pipeline companies and has been for months, the Christian Science Monitor reports, citing alerts issued to the industry by the Homeland Security Department.
It says that DHS has issued at least three confidential "amber" alerts warning of a "gas pipeline sector cyber intrusion campaign" against multiple pipeline companies.
The newspaper also quotes alerts from DHS’s Industrial Control Systems Cyber Emergency Response Team (ICS-CERT).
“ICS-CERT has recently identified an active series of cyber intrusions targeting natural gas pipeline sector companies," it quotes an April 13 advisory as saying. "Multiple natural-gas-pipeline organizations have reported either attempts or intrusions related to this campaign. The campaign appears to have started in late December 2011 and is active today."
