WASHINGTON - A break-in targeting State Department computers worldwide 
last summer occurred after a department employee in Asia opened a 
mysterious e-mail that quietly allowed hackers inside the U.S. 
government's network.

In the first public account revealing details about the intrusion and 
the government's hurried behind-the-scenes response, a senior State 
Department official described an elaborate ploy by sophisticated 
international hackers. They used a secret break-in technique that 
exploited a design flaw in Microsoft software.

Consumers using the same software remained vulnerable until months 
afterward.

Donald R. Reid, the senior security coordinator for the Bureau of 
Diplomatic Security, also confirmed that a limited amount of U.S. 
government data was stolen by the hackers until tripwires severed all 
the State Department's Internet connections throughout eastern Asia. The 
shut-off left U.S. government offices without Internet access in the 
tense weeks preceding missile tests by North Korea.

Reid was scheduled to testify Thursday at a cybersecurity hearing for a 
House Homeland Security subcommittee. He was expected to tell lawmakers 
an employee in the State Department's Bureau of East Asian and Pacific 
Affairs which coordinates diplomacy in countries including China, the 
Koreas and Japan opened a rigged e-mail message in late May giving 
hackers access to the government's network.

The chairman of the Homeland Security Committee, Rep. Bennie Thompson, 
D-Miss., said hackers are no longer considered harmless, bored 
teenagers. These are experienced, sophisticated people who are trying to 
exploit our vulnerabilities and gain access to our information, Thompson 
said.

Reid was not expected to disclose the identities or nationalities of the 
hackers believed to be responsible for the break-ins or to disclose 
whether U.S. authorities believe a foreign government was responsible. 
The department struggled with the break-ins between May and early July.

The panel's chairman, Rep. James R. Langevin, D-R.I., called 
cybersecurity an often-overlooked line of defense. Since much of our 
critical infrastructure is dependent on computers and networks and is 
interconnected and interdependent, a cyberattack could disrupt major 
services and cripple economic activity, Langevin said.

The mysterious State Department e-mail appeared to be legitimate and 
included a Microsoft Word document with material from a congressional 
speech related to Asian diplomacy, Reid said. By opening the document, 
the employee activated hidden software commands establishing what Reid 
described as backdoor communications with the hackers.

The technique exploited a previously unknown design flaw in Microsoft's 
Office software, Reid said. State Department officials worked with the 
Homeland Security Department and even the FBI to urge Microsoft to 
develop quickly a protective software patch, but the company did not 
offer the patch until Aug. 8 roughly eight weeks after the break-in.

At the time, Microsoft described the software flaw as a newly 
discovered, privately reported vulnerability but did not suggest any 
connection to the U.S. government break-in. It urged consumers to apply 
the update immediately. It also recommended that consumers not open or 
save Microsoft Office files they receive from sources they don't trust 
or files they receive unexpectedly from trusted sources.

The State Department detected its first break-in immediately, Reid said, 
and worked to block suspected communications with the hackers. But 
during its investigation, it discovered new break-ins at its Washington 
headquarters and other offices in eastern Asia, Reid said.

At first, the hackers did not immediately appear to try stealing any 
U.S. government data. Authorities quietly monitored the hackers' 
activity, then tripwires severed Internet connections in the region 
after a limited amount of data was detected being stolen, Reid said.

Reid also complained the State Department's efforts to deal quietly with 
the break-in were disrupted by news reports. The Associated Press was 
first to reveal the intrusions.

We were successful here until a newspaper article telegraphed what we 
were dealing with, Reid said.
