Do Antivirus Companies Whitelist NSA Malware?Do Antivirus Companies Whitelist NSA Malware?
Microsoft, Symantec, and McAfee fail to respond to a transparency plea from leading privacy and security experts.

Dear antivirus vendors: Are you aiding and abetting National Security Agency (NSA) spying?
That's the subject of an open letter, sent in October to leading antivirus vendors, from 25 different privacy information security experts and organizations. The letter asks the vendors to detail whether they've ever detected state-sponsored malware or received a government request to whitelist state-sponsored malware, and how they would respond to any such requests in the future.
The letter, sent from Dutch digital rights foundation Bits of Freedom, requested that the firms respond by November 15. "Please let us know if you feel that you cannot, or cannot fully, answer any of the above questions because of legal constraints imposed upon you by any government," it said.
"Since we learned that the NSA has surreptitiously weakened Internet security so it could more easily eavesdrop, we've been wondering if it's done anything to antivirus products," letter signatory Bruce Schneier, chief security technology officer of BT, said in a blog post. "Given that it engages in offensive cyberattacks -- and launches cyberweapons like Stuxnet and Flame -- it's reasonable to assume that it's asked antivirus companies to ignore its malware. We know that antivirus companies have previously done this for corporate malware."
As of two weeks ago, however, only six security vendors -- ESET, F-Secure, Kaspersky Lab, Norman Shark, Panda, and Trend Micro -- had responded to the request for information. Even so, the news was good. "All of the responding companies have confirmed the detection of state sponsored malware, e.g. R2D2 and FinFisher," according to researcher Ton Siedsma at Bits of Freedom. "Furthermore, they claim they have never received a request to not detect malware. And if they were asked by any government to do so in the future, they said they would not comply."
More recently, meanwhile, Avira CEO Travis Witteveen reported, in a letter to Bits of Freedom, that his company likewise had no time for state-sponsored malware, and said the company would change its headquarters to a foreign country if the German government ever ordered it to ignore any type of malware. Likewise, the CEO of BitDefender, speaking by phone, said that his company had never received a copy of the letter from Bits of Freedom, but that his company would never -- and had never -- whitelisted any form of malware. The company plans to soon publish a more detailed statement on its website.
No malware is harmless
That, of course, gets to the crux of the matter: Is there any such thing as benign malware? Most, if not all, security experts would argue otherwise. "All the aforementioned companies believe there is no such thing as harmless malware," Bits of Freedom’s Siedsma noted.
Hence it's odd that US-based McAfee, Microsoft, and Symantec all failed to respond to Bits of Freedom's letter before the deadline. (Siedsma at Bits of Freedom didn't immediately respond to an emailed question about whether any have done so since then.) Ditto for Agnitum (Russia), Ahnlab (South Korea), Avast (Czech Republic), AVG (Czech Republic), and Bullguard (United Kingdom).
Firms that did respond, by contrast, were largely outspoken in their attitude toward state-sponsored malware. "We have a very simple and straightforward policy as it relates to the detection of malware: We detect and remediate any malware attack, regardless of its origin or purpose. There is no such thing as 'right' or 'wrong' malware for us," according to Kaspersky Lab's statement.
Likewise, Christian Fredrikson, president and CEO of Finnish antivirus vendor F-Secure, argued that malware has no shades of gray. "If it's malware, we will protect our customers from it," he wrote to Bits of Freedom. "Our decision-making boils down to a simple question: would our customers want to run this program on their system or not. Obviously the answer for governmental Trojans would be a 'No.' "
Ignoring malware of any stripe leads to collateral damage. For example, take the Stuxnet virus, which was allegedly developed by the United States and Israel under the so-called "Olympic Games" cyberweapon program, and which was designed to sabotage the high-frequency convertor drives used in centrifuges inside the Iranian nuclear facility at Natanz.
Security firms, in fact, were the first to discover Stuxnet -- in July 2010 -- and soon began sounding related warnings. While Stuxnet was designed to not cause damage to any other systems outside of Natanz, it did infect numerous other systems, for example at energy giant Chevron, triggering panic and cleanup costs.
For the record, whatever antivirus vendors' attitude toward state-sponsored malware, whether or not they detect it won't necessarily stop the spread of such malware. In part, that's because for an antivirus firm to spot malware, it first needs to have seen the malware, recognized that it's malicious code, and written a corresponding virus signature for its products. In addition, intelligence agencies no doubt work overtime -- and occasionally make use of zero-day vulnerabilities -- to ensure that their malicious code escapes detection. They're probably quite successful at doing so. For example, leaked documents suggest that by 2012, the NSA had installed malware on more than 50,000 PCs used by US government targets.
Given that level of success, it's unlikely, argued Schneier, that any intelligence or law enforcement agencies would try to tell domestic antivirus firms what to do. "Antivirus is a very international industry, and while a government might get its own companies to play along, it would not be able to influence international companies," he said.
But if that's the case, what's to account for the silence from McAfee, Microsoft, and Symantec, and the other antivirus firm holdouts?
