More on the CIA Document Leak

If I had to guess right now, I’d say the documents came from an outsider and not an insider. My reasoning: One, there is absolutely nothing illegal in the contents of any of this stuff. It’s exactly what you’d expect the CIA to be doing in cyberspace. That makes the whistleblower motive less likely. And two, the documents are a few years old, making this more like the Shadow Brokers than Edward Snowden. An internal leaker would leak quickly. A foreign intelligence agency — like the Russians — would use the documents while they were fresh and valuable, and only expose them when the embarrassment value was greater.

James Lewis agrees:

But James Lewis, an expert on cybersecurity at the Center for Strategic and International Studies in Washington, raised another possibility: that a foreign state, most likely Russia, stole the documents by hacking or other means and delivered them to WikiLeaks, which may not know how they were obtained. Mr. Lewis noted that, according to American intelligence agencies, Russia hacked Democratic targets during the presidential campaign and gave thousands of emails to WikiLeaks for publication.

To be sure, neither of us has any idea. We’re all guessing.

To the documents themselves, I really liked these best practice coding guidelines for malware, and these crypto requirements.

I am mentioned in the latter document:

Cryptographic jargon is utilized throughout this document. This jargon has precise and subtle meaning and should not be interpreted without careful understanding of the subject matter. Suggested reading includes Practical Cryptography by Schneier and Ferguson, RFCs 4251 and 4253, RFCs 5246 and 5430, and Handbook of Applied Cryptography by Menezes, van Oorschot, and Vanstone.

EDITED TO ADD: Herbert Lin comments.

The most damning thing I’ve seen so far is yet more evidence that — despite assurances to the contrary — the US intelligence community hoards vulnerabilities in common Internet products and uses them for offensive purposes.

EDITED TO ADD (3/9): The New York Times is reporting that the CIA suspects an insider:

Investigators say that the leak was the work not of a hostile foreign power like Russia but of a disaffected insider, as WikiLeaks suggested when it released the documents Tuesday. The F.B.I. was preparing to interview anyone who had access to the information, a group likely to include at least a few hundred people, and possibly more than a thousand.

An intelligence official said the information, much of which appeared to be technical documents, may have come from a server outside the C.I.A. managed by a contractor. But neither he nor a former senior intelligence official ruled out the possibility that the leaker was a C.I.A. employee.

EDITED TO ADD (3/9): WikiLeaks said that they have published less than 1% of what they have, and that they are giving affected companies an early warning of the vulnerabilities and tools that they’re publishing.

A Comment on the Trump Dossier

Imagine that you are someone in the CIA, concerned about the future of America. You have this Russian dossier on Donald Trump, which you have some evidence might be true. The smartest thing you can do is to leak it to the public. By doing so, you are eliminating any leverage Russia has over Trump and probably reducing the effectiveness of any other blackmail material any government might have on Trump. I believe you do this regardless of whether you ultimately believe the document’s findings or not, and regardless of whether you support or oppose Trump. It’s simple game-theory.

This document is particularly safe to release. Because it’s not a classified report of the CIA, leaking it is not a crime. And you release it now, before Trump becomes president, because doing so afterwards becomes much more dangerous.

MODERATION NOTE: Please keep comments focused on this particular point. More general comments, especially uncivil comments, will be deleted.

Attributing the DNC Hacks to Russia

President Barack Obama’s public accusation of Russia as the source of the hacks in the US presidential election and the leaking of sensitive e-mails through WikiLeaks and other sources has opened up a debate on what constitutes sufficient evidence to attribute an attack in cyberspace. The answer is both complicated and inherently tied up in political considerations.

The administration is balancing political considerations and the inherent secrecy of electronic espionage with the need to justify its actions to the public. These issues will continue to plague us as more international conflict plays out in cyberspace.

It’s true that it’s easy for an attacker to hide who he is in cyberspace. We are unable to identify particular pieces of hardware and software around the world positively. We can’t verify the identity of someone sitting in front of a keyboard through computer data alone. Internet data packets don’t come with return addresses, and it’s easy for attackers to disguise their origins. For decades, hackers have used techniques such as jump hosts, VPNs, Tor and open relays to obscure their origin, and in many cases they work. I’m sure that many national intelligence agencies route their attacks through China, simply because everyone knows lots of attacks come from China.

On the other hand, there are techniques that can identify attackers with varying degrees of precision. It’s rarely just one thing, and you’ll often hear the term “constellation of evidence” to describe how a particular attacker is identified. It’s analogous to traditional detective work. Investigators collect clues and piece them together with known mode of operations. They look for elements that resemble other attacks and elements that are anomalies. The clues might involve ones and zeros, but the techniques go back to Sir Arthur Conan Doyle.

The University of Toronto-based organization Citizen Lab routinely attributes attacks against the computers of activists and dissidents to particular Third World governments. It took months to identify China as the source of the 2012 attacks against the New York Times. While it was uncontroversial to say that Russia was the source of a cyberattack against Estonia in 2007, no one knew if those attacks were authorized by the Russian government — until the attackers explained themselves. And it was the Internet security company CrowdStrike, which first attributed the attacks against the Democratic National Committee to Russian intelligence agencies in June, based on multiple pieces of evidence gathered from its forensic investigation.

Attribution is easier if you are monitoring broad swaths of the Internet. This gives the National Security Agency a singular advantage in the attribution game. The problem, of course, is that the NSA doesn’t want to publish what it knows.

Regardless of what the government knows and how it knows it, the decision of whether to make attribution evidence public is another matter. When Sony was attacked, many security experts — myself included­ — were skeptical of both the government’s attribution claims and the flimsy evidence associated with it. I only became convinced when the New York Times ran a story about the government’s attribution, which talked about both secret evidence inside the NSA and human intelligence assets inside North Korea. In contrast, when the Office of Personnel Management was breached in 2015, the US government decided not to accuse China publicly, either because it didn’t want to escalate the political situation or because it didn’t want to reveal any secret evidence.

The Obama administration has been more public about its evidence in the DNC case, but it has not been entirely public.

It’s one thing for the government to know who attacked it. It’s quite another for it to convince the public who attacked it. As attribution increasingly relies on secret evidence­ — as it did with North Korea’s attack of Sony in 2014 and almost certainly does regarding Russia and the previous election — ­the government is going to have to face the choice of making previously secret evidence public and burning sources and methods, or keeping it secret and facing perfectly reasonable skepticism.

If the government is going to take public action against a cyberattack, it needs to make its evidence public. But releasing secret evidence might get people killed, and it would make any future confidentiality assurances we make to human sources completely non-credible. This problem isn’t going away; secrecy helps the intelligence community, but it wounds our democracy.

The constellation of evidence attributing the attacks against the DNC, and subsequent release of information, is comprehensive. It’s possible that there was more than one attack. It’s possible that someone not associated with Russia leaked the information to WikiLeaks, although we have no idea where that someone else would have obtained the information. We know that the Russian actors who hacked the DNC­ — both the FSB, Russia’s principal security agency, and the GRU, Russia’s military intelligence unit — ­are also attacking other political networks around the world.

In the end, though, attribution comes down to whom you believe. When Citizen Lab writes a report outlining how a United Arab Emirates human rights defender was targeted with a cyberattack, we have no trouble believing that it was the UAE government. When Google identifies China as the source of attacks against Gmail users, we believe it just as easily.

Obama decided not to make the accusation public before the election so as not to be seen as influencing the election. Now, afterward, there are political implications in accepting that Russia hacked the DNC in an attempt to influence the US presidential election. But no amount of evidence can convince the unconvinceable.

The most important thing we can do right now is deter any country from trying this sort of thing in the future, and the political nature of the issue makes that harder. Right now, we’ve told the world that others can get away with manipulating our election process as long as they can keep their efforts secret until after one side wins. Obama has promised both secret retaliations and public ones. We need to hope they’re enough.

Another Shadow Brokers Leak

There’s another leak of NSA hacking tools and data from the Shadow Brokers. This one includes a list of hacked sites.

According to analyses from researchers here and here, Monday’s dump contains 352 distinct IP addresses and 306 domain names that purportedly have been hacked by the NSA. The timestamps included in the leak indicate that the servers were targeted between August 22, 2000 and August 18, 2010. The addresses include 32 .edu domains and nine .gov domains. In all, the targets were located in 49 countries, with the top 10 being China, Japan, Korea, Spain, Germany, India, Taiwan, Mexico, Italy, and Russia. Vitali Kremez, a senior intelligence analyst at security firm Flashpoint, also provides useful analysis here.

The dump also includes various other pieces of data. Chief among them are configuration settings for an as-yet unknown toolkit used to hack servers running Unix operating systems. If valid, the list could be used by various organizations to uncover a decade’s worth of attacks that until recently were closely guarded secrets. According to this spreadsheet, the servers were mostly running Solaris, an operating system from Sun Microsystems that was widely used in the early 2000s. Linux and FreeBSD are also shown.

The data is old, but you can see if you’ve been hacked.

Honestly, I am surprised by this release. I thought that the original Shadow Brokers dump was everything. Now that we know they held things back, there could easily be more releases.

EDITED TO ADD (11/6): More on the NSA targets. Note that the Hague-based Organization for the Prohibition of Chemical Weapons is on the list, hacked in 2000.

NSA Contractor Arrested for Stealing Classified Information

The NSA has another contractor who stole classified documents. It’s a weird story: “But more than a month later, the authorities cannot say with certainty whether Mr. Martin leaked the information, passed them on to a third party or whether he simply downloaded them.” So maybe a potential leaker. Or a spy. Or just a document collector.

My guess is that there are many leakers inside the US government, even more than what’s on this list from last year.

EDITED TO ADD (10/7): More information.

Leaked Product Demo from RCS Labs

We have leak from yet another cyberweapons arms manufacturer: the Italian company RCS Labs. Vice Motherboard reports on a surveillance video demo:

The video shows an RCS Lab employee performing a live demo of the company’s spyware to an unidentified man, including a tutorial on how to use the spyware’s control software to perform a man-in-the-middle attack and infect a target computer who wanted to visit a specific website.

RCS Lab’s spyware, called Mito3, allows agents to easily set up these kind of attacks just by applying a rule in the software settings. An agent can choose whatever site he or she wants to use as a vector, click on a dropdown menu and select “inject HTML” to force the malicious popup to appear, according to the video.

Mito3 allows customers to listen in on the target, intercept voice calls, text messages, video calls, social media activities, and chats, apparently both on computer and mobile platforms. It also allows police to track the target and geo-locate it thanks to the GPS. It even offers automatic transcription of the recordings, according to a confidential brochure obtained by Motherboard.

Internet Disinformation Service for Hire

Yet another leaked catalog of Internet attack services, this one specializing in disinformation:

But Aglaya had much more to offer, according to its brochure. For eight to 12 weeks campaigns costing €2,500 per day, the company promised to “pollute” internet search results and social networks like Facebook and Twitter “to manipulate current events.” For this service, which it labelled “Weaponized Information,” Aglaya offered “infiltration,” “ruse,” and “sting” operations to “discredit a target” such as an “individual or company.”

“[We] will continue to barrage information till it gains ‘traction’ & top 10 search results yield a desired results on ANY Search engine,” the company boasted as an extra “benefit” of this service.

Aglaya also offered censorship-as-a-service, or Distributed Denial of Service (DDoS) attacks, for only €600 a day, using botnets to “send dummy traffic” to targets, taking them offline, according to the brochure. As part of this service, customers could buy an add-on to “create false criminal charges against Targets in their respective countries” for a more costly €1 million.

[…]

Some of Aglaya’s offerings, according to experts who reviewed the document for Motherboard, are likely to be exaggerated or completely made-up. But the document shows that there are governments interested in these services, which means there will be companies willing to fill the gaps in the market and offer them.
