DCAC: A Field Day for the Heat

“Domestic Communications Assistance Center” is the kind of name you’d give to a couples counseling collective. At the FBI, though, it’s the name that’s been given to an agency designed to be at the cutting edge of digital snooping.

The mission of the DCAC, located at the FBI facility in Quantico, Va., includes intercepting and decoding Skype conversations, building wiretap hardware, developing tools for analyzing gigabytes of data obtained from wireless carriers or social networks and providing a help desk for minor league snoopers like state and local police, according to a report by Declan McCullagh in Cnet last week.

The center is part of an initiative within the U.S. Justice Department called “Going Dark,” which refers to law enforcement’s diminishing ability to keep tabs on technology-savvy criminals and terrorists.

Much of law enforcement’s authority to eavesdrop on threats to law and order comes from the 1994 Communications Assistance for Law Enforcement Act (CALEA).

“When CALEA was passed, things were fairly simple,” Steve Bock, president of Subsentio, a security consulting firm, explained to TechNewsWorld. “There were two networks: wireline and wireless.”

“Now we have a network or networks,” he continued. “It’s very complicated.”

A rewrite of the law would be useful, he maintained. “There are so many security holes in our nation’s networks for criminals and terrorists to communicate with each other that the current structure simply does not work,” he added.

Security holes or not, the level of secrecy surrounding the DCAC concerns some government watchdogs. “It’s important for Congress and the public to know what capabilities are being developed at the DCAC so they can evaluate what the FBI is doing,” Gregory T. Nojeim, director of the Project on Freedom, Security and Technology at the Center for Democracy & Technology.

Good Year for Malware

McAfee released its first-quarter threats report last week. It revealed that malware samples collected during the period hit a new four-year high and could reach 100 million samples by year’s end.

One threat vector that will continue to grow in the coming months will be infected websites, according to McAfee Labs Messaging Data Architect Adam Wosotowsky.

“Many of those sites are in the United States,” he told TechNewsWorld. “In fact, the United States is most prolific attacker of other country’s websites in the world.”

In some ways, the United States is paying for being ahead of the world on Internet development, he observed. “For that reason, we’re also the world leader of web pages that haven’t been updated in five years,” he said.

“When you have a Web page that hasn’t been updated in five years and you’re using something like PHP or MySQL, then you can be open to MySQL injection attacks or cross-site scripting,” he explained.

Wosotowsky also waved a red flag over the growing number of botnet software development kits (SDKs) appearing on the Net’s black market. “That’s something that’s going to increase over time,” he noted. “That’s going to be a large danger area.”

Trust on the Internet

Last year, a virtual earthquake shook the trust structure of the Internet. DigiNotar, a company that issues certificates used by browsers to establish secure connections on the Web, was hacked and its certificates used to spy on some 300,000 Google Gmail users.

A proposal that would address the flaw in the certificate system that facilitated that attack was submitted last week to the Internet Engineering Task Force, a standards group.

The proposal would create a new extension, called the “Trust Assertions for Certificate Keys” (TACK), for the Net’s trust system. After a Web surfer with a TACK-enabled browser visits a site that’s using the technology a few times, a “pin” would be created on the user’s computer. If the user encounters a site masquerading as the pinned location, the browser will reject the session and alert the user that something is wrong.

The extension, which was submitted by Moxie Marlinspike and Trevor Perrin, received high praise from cryptographer Nate Lawson. “It really is one of the few initiatives in recent times to have a huge impact on your family’s actual security, as well as dissidents in countries like Iran,” he wrote at the Hacker News forum.
