An anonymous reader writes: Brian Krebs reports on information from Columbia, Md.-based threat intelligence firm Cyber Engineering Services Inc. that attackers thought to be operating out of China hacked into the corporate networks of three top Israeli defense technology companies. The attackers were seeking technical documents related to Iron Dome, Israel's air defense system. "IAI was initially breached on April 16, 2012 by a series of specially crafted email phishing attacks. ... Once inside the IAI’s network, [the attackers] spent the next four months in 2012 using their access to install various tools and trojan horse programs on systems throughout company’s network and expanding their access to sensitive files, CyberESI said. The actors compromised privileged credentials, dumped password hashes, and gathered system, file, and network information for several systems. The actors also successfully used tools to dump Active Directory data from domain controllers on at least two different domains on the IAI’s network. All told, CyberESI was able to identify and acquire more than 700 files — totaling 762 MB total size — that were exfiltrated from IAI’s network during the compromise. The security firm said most of the data acquired was intellectual property and likely represented only a small portion of the entire data loss by IAI." Most of the stolen material pertained to Arrow III missiles, UAVs, and ballistic rockets.
