Chinese hackers attacked New York Times computers for four months

This is why you employ defense-in-depth and full network monitoring, even if you don’t care what websites your employees visit at work.

But while the company was informed by AT&T of suspicious activity over its network connection on October 25—the day the Wen story was published—the attack had begun weeks earlier and appears to have been focused on getting into the e-mail accounts of Times Shanghai Bureau Chief David Barboza and South Asia Bureau Chief Jim Yardley. The attack used 45 different pieces of custom malware code, including remote access tools that gave Chinese hackers the run of the Times’ network.

The attackers used a botnet of computers compromised at US universities to obscure the source of the attack. They then infected computers at the Times with malware, most likely through e-mail “spear phishing” attacks, and used the malware to install remote access tools on at least three target systems that allowed them to gather more information from the network—finally finding the Windows network domain controller and grabbing its user directory and password tables. The hackers then used the cracked passwords to access other systems and created a custom program built to infiltrate the Times‘ mailserver to search all the e-mails and documents sent to Barboza and Yardley’s accounts—apparently searching for the names of people who may have spoken to Barboza as he reported on the Wen family.
