Newly discovered hack has U.S. fearing foreign infiltration

A major breach at computer network company Juniper Networks has U.S. officials worried that hackers working for a foreign government were able to spy on the encrypted communications of the U.S. government and private companies for the past three years.

The FBI is investigating the breach, which involved hackers installing a back door on computer equipment, U.S. officials told CNN. JuniperĀ disclosed the issue along with an emergency security patch that it urged customers to use to update their systems “with the highest priority.”

The concern, U.S. officials said, is that sophisticated hackers who compromised the equipment could use their access to get into any company or government agency that used it.

One U.S. official described it as akin to “stealing a master key to get into any government building.”

The breach is believed to be the work of a foreign government, U.S. officials said, because of the sophistication involved. The U.S. officials said they are certain U.S. spy agencies themselves aren’t behind the back door. China and Russia are among the top suspected governments, though officials cautioned the investigation hasn’t reached conclusions.

It’s not yet clear what if any classified information could be affected, but U.S. officials said the Juniper Networks equipment is so widely used that it may take some time to determine what damage was done.

A senior administration official told CNN, “We are aware of the vulnerabilities recently announced by Juniper. The Department of Homeland Security has been and remains in close touch with the company. The administration remains committed to enhancing our national cybersecurity by raising our cyber defenses, disrupting adversary activity, and effectively responding to incidents when they occur.”

Juniper Networks’ security fix is intended to seal a back door that hackers created in order to remotely log into commonly used VPN networks to spy on communications that were supposed to be among the most secure.

Juniper said that someone managed to get into its systems and write “unauthorized code” that “could allow a knowledgeable attacker to gain administrative access.”

Such access would allow the hacker to monitor encrypted traffic on the computer network and decrypt communications.

Juniper sells computer network equipment and routers to big companies and to U.S. government clients such as the Defense Department, Justice Department, FBI and Treasury Department. On its website, the company boasts of providing networks that “US intelligence agencies require.”

Its routers and network equipment are widely used by corporations, including for secure communications. Homeland Security officials are now trying to determine how many such systems are in use for U.S. government networks.

Juniper said in its security alert that it wasn’t aware of any “malicious exploitation of these vulnerabilities.” However, the alert also said that attackers would leave behind no trace of their activity by removing security logs that would show a breach.

“Note that a skilled attacker would likely remove these entries from the log file, thus effectively eliminating any reliable signature that the device had been compromised,” the Juniper security alert said. If encrypted communications were being monitored, “There is no way to detect that this vulnerability was exploited,” according to theĀ Juniper security alert.

According to a Juniper Networks spokeswoman’s statement, “Once we identified these vulnerabilities, we launched an investigation and worked to develop and issue patched releases for the impacted devices. We also reached out to affected customers, strongly recommending that they update their systems.”

U.S. officials said it’s not clear how the Juniper source code was altered, whether from an outside attack or someone inside.

The work to alter millions of lines of source code is sophisticated. The system was compromised for three years before Juniper uncovered it in a routine review in recent weeks.

Juniper said it was also issuing a security fix for a separate bug that could allow a hacker to launch denial-of-service attacks on networks.
