New Variant of Havex Malware Scans for OPC Servers at SCADA Systems
Jul 19, 2014
At the beginning of the month, we have reported about the new surge of a Stuxnet-like malware "Havex" , which was previously targeting organizations in the energy sector, had been used to carry out industrial espionage against a number of companies in Europe and compromised over 1,000 European and North American energy firms. Recently, researchers at security firm FireEye have discovered a new variant of Havex remote access Trojan that has capability to actively scan OPC ( Object linking and embedding for Process Control ) servers, used for controlling SCADA (Supervisory Control and Data Acquisition) systems in critical infrastructure, energy, and manufacturing sectors. OPC is a communications standard that allows interaction between Windows-based SCADA or other industrial control systems (ICS) applications and process control hardware. New Havex variant gathers system information and data stored on a compromised client or server using the OPC standard. OPC is pervasive and...
