Bart Gellman on Snowden

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2020/05/bart_gellman_on.html

Bart Gellman’s long-awaited (at least by me) book on Edward Snowden, Dark Mirror: Edward Snowden and the American Surveillance State, will finally be published in a couple of weeks. There is an adapted excerpt in the Atlantic.

It’s an interesting read, mostly about the government surveillance of him and other journalists. He speaks about an NSA program called FIRSTFRUITS that specifically spies on US journalists. (This isn’t news; we learned about this in 2006. But there are lots of new details.)

One paragraph in the excerpt struck me:

Years later Richard Ledgett, who oversaw the NSA’s media-leaks task force and went on to become the agency’s deputy director, told me matter-of-factly to assume that my defenses had been breached. “My take is, whatever you guys had was pretty immediately in the hands of any foreign intelligence service that wanted it,” he said, “whether it was Russians, Chinese, French, the Israelis, the Brits. Between you, Poitras, and Greenwald, pretty sure you guys can’t stand up to a full-fledged nation-state attempt to exploit your IT. To include not just remote stuff, but hands-on, sneak-into-your-house-at-night kind of stuff. That’s my guess.”

I remember thinking the same thing. It was the summer of 2013, and I was visiting Glenn Greenwald in Rio de Janeiro. This was just after Greenwald’s partner was detained in the UK trying to ferry some documents from Laura Poitras in Berlin back to Greenwald. It was an opsec disaster; they would have been much more secure if they’d emailed the encrypted files. In fact, I told them to do that, every single day. I wanted them to send encrypted random junk back and forth constantly, to hide when they were actually sharing real data.

As soon as I saw their house I realized exactly what Ledgett said. I remember standing outside the house, looking into the dense forest for TEMPEST receivers. I didn’t see any, which only told me they were well hidden. I assumed black-bag teams from various countries had been all over the house when they were out for dinner, and wondered what would have happened if teams from different countries bumped into each other. I assumed that all the countries Ledgett listed above — plus the US and a few more — had a full take of what Snowden gave the journalists. These journalists against those governments just wasn’t a fair fight.

I’m looking forward to reading Gellman’s book. I’m kind of surprised no one sent me an advance copy.

Identifying and Arresting Ransomware Criminals

The Wall Street Journal has a story about how two people were identified as the perpetrators of a ransomware scheme. They were found because — as generally happens — they made mistakes covering their tracks. They were investigated because they had the bad luck of locking up Washington, DC’s video surveillance cameras a week before the 2017 inauguration.

Details on Uzbekistan Government Malware: SandCat

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2019/10/details_on_uzbe.html

Kaspersky has uncovered an Uzbeki hacking operation, mostly due to incompetence on the part of the government hackers.

The group’s lax operational security includes using the name of a military group with ties to the SSS to register a domain used in its attack infrastructure; installing Kaspersky’s antivirus software on machines it uses to write new malware, allowing Kaspersky to detect and grab malicious code still in development before it’s deployed; and embedding a screenshot of one of its developer’s machines in a test file, exposing a major attack platform as it was in development. The group’s mistakes led Kaspersky to discover four zero-day exploits SandCat had purchased from third-party brokers to target victim machines, effectively rendering those exploits ineffective. And the mistakes not only allowed Kaspersky to track the Uzbek spy agency’s activity but also the activity of other nation-state groups in Saudi Arabia and the United Arab Emirates who were using some of the same exploits SandCat was using.

New Research into Russian Malware

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2019/10/new_research_in_1.html

There’s some interesting new research about Russian APT malware:

The Russian government has fostered competition among the three agencies, which operate independently from one another, and compete for funds. This, in turn, has resulted in each group developing and hoarding its tools, rather than sharing toolkits with their counterparts, a common sight among Chinese and North Korean state-sponsored hackers.

“Every actor or organization under the Russain APT umbrella has its own dedicated malware development teams, working for years in parallel on similar malware toolkits and frameworks,” researchers said.

“While each actor does reuse its code in different operations and between different malware families, there is no single tool, library or framework that is shared between different actors.”

Researchers say these findings suggest that Russia’s cyber-espionage apparatus is investing a lot of effort into its operational security.

“By avoiding different organizations re-using the same tools on a wide range of targets, they overcome the risk that one compromised operation will expose other active operations,” researchers said.

This is no different from the US. The NSA malware released by the Shadow Brokers looked nothing like the CIA “Vault 7” malware released by WikiLeaks.

The work was done by Check Point and Intezer Labs. They have a website with an interactive map.
