Canadian energy firm Telvent confirms a security breach involving the project files of some of its customers. Security blogger Brian Krebs disclosed how hackers believed to be from China had breached Telvent. The intruders broke through the company’s firewall earlier this month, he said. Telvent’s SCADA systems are used to control more than half of all oil and gas pipelines in North America and Latin America. The company appears to have been attacked by a notorious Chinese hacking group called the Common Group, Krebs said.”]
