Modern ransomware has two dimensions: pay to get your data back, and pay not to have your data dumped on the Internet. The DC police are the victims of this ransomware, and the criminals have just posted personnel records — “including the results of psychological assessments and polygraph tests; driver’s license images; fingerprints; social security numbers; dates of birth; and residential, financial, and marriage histories” — for two dozen police officers.
The negotiations don’t seem to be doing well. The criminals want $4M. The DC police offered them $100,000.
The Colonial Pipeline is another current high-profile ransomware victim. (Brian Krebs has some good information on DarkSide, the criminal group behind that attack.) So is Vastaamo, a Finnish mental heal clinic. Criminals contacted the individual patients and demanded payment, and then dumped their personal psychological information online.
An industry group called the Institute for Security and Technology (no, I haven’t heard of it before, either) just released a comprehensive report on combating ransomware. It has a “comprehensive plan of action,” which isn’t much different from anything most of us can propose. Solving this is not easy. Ransomware is big business, made possible by insecure networks that allow criminals to gain access to networks in the first place, and cryptocurrencies that allow for payments that governments cannot interdict. Ransomware has become the most profitable cybercrime business model, and until we solve those two problems, that’s not going to change.

President Biden signed an executive order to improve government cybersecurity, setting new security standards for software sold to the federal government.
For the first time, the United States will require all software purchased by the federal government to meet, within six months, a series of new cybersecurity standards. Although the companies would have to “self-certify,” violators would be removed from federal procurement lists, which could kill their chances of selling their products on the commercial market.
I’m a big fan of these sorts of measures. The US government is a big enough market that vendors will try to comply with procurement regulations, and the improvements will benefit all customers of the software.
More news articles.

Microsoft researchers just released an open-source automation tool for security testing AI systems: “Counterfit.” Details on their blog.

This is a major story: a probably Russian cybercrime group called DarkSide shut down the Colonial Pipeline in a ransomware attack. The pipeline supplies much of the East Coast. This is the new and improved ransomware attack: the hackers stole nearly 100 gig of data, and are threatening to publish it. The White House has declared a state of emergency and has created a task force to deal with the problem, but it’s unclear what they can do. This is bad; our supply chains are so tightly coupled that this kind of thing can have disproportionate effects.
EDITED TO ADD (5/12): It seems that the billing system was attacked, and not the physical pipeline itself.

This is a newly unclassified NSA history of its reaction to academic cryptography in the 1970s: “NSA Comes Out of the Closet: The Debate over Public Cryptography in the Inman Era,” Cryptographic Quarterly, Spring 1996, author still classified.

A town in Japan built a giant squid statue with its COVID relief grant.
One local told the Chunichi Shimbun newspaper that while the statue may be effective in the long run, the money could have been used for “urgent support,” such as for medical staff and long-term care facilities.
But a spokesperson for the town told Fuji News Network that the statue would be a tourist attraction and part of a long term strategy to help promote Noto’s famous flying squid.
I am impressed by the town’s sense of priorities.
As usual, you can also use this squid post to talk about the security stories in the news that I haven’t covered.

A new draft of an Australian educational curriculum proposes teaching children as young as five cybersecurity:
The proposed curriculum aims to teach five-year-old children — an age at which Australian kids first attend school — not to share information such as date of birth or full names with strangers, and that they should consult parents or guardians before entering personal information online.
Six-and-seven-year-olds will be taught how to use usernames and passwords, and the pitfalls of clicking on pop-up links to competitions.
By the time kids are in third and fourth grade, they’ll be taught how to identify the personal data that may be stored by online services, and how that can reveal their location or identity. Teachers will also discuss “the use of nicknames and why these are important when playing online games.”
By late primary school, kids will be taught to be respectful online, including “responding respectfully to other people’s opinions even if they are different from personal opinions.”
I have mixed feeling about this. Norms around these things are changing so fast, and it’s not likely that we in the older generation will get to dictate what the younger generation does. But these sorts of online privacy conversations are worth having around the same time children learn about privacy in other contexts.

There’s new research that demonstrates security vulnerabilities in all of the AMD and Intel chips with micro-op caches, including the ones that were specifically engineered to be resistant to the Spectre/Meltdown attacks of three years ago.
The new line of attacks exploits the micro-op cache: an on-chip structure that speeds up computing by storing simple commands and allowing the processor to fetch them quickly and early in the speculative execution process, as the team explains in a writeup from the University of Virginia. Even though the processor quickly realizes its mistake and does a U-turn to go down the right path, attackers can get at the private data while the processor is still heading in the wrong direction.
It seems really difficult to exploit these vulnerabilities. We’ll need some more analysis before we understand what we have to patch and how.

This is an impressive hack:
Security researchers Ralf-Philipp Weinmann of Kunnamon, Inc. and Benedikt Schmotzle of Comsecuris GmbH have found remote zero-click security vulnerabilities in an open-source software component (ConnMan) used in Tesla automobiles that allowed them to compromise parked cars and control their infotainment systems over WiFi. It would be possible for an attacker to unlock the doors and trunk, change seat positions, both steering and acceleration modes — in short, pretty much what a driver pressing various buttons on the console can do. This attack does not yield drive control of the car though.
That last sentence is important.

The person behind the Bitcoin Fog was identified and arrested. Bitcoin Fog was an anonymization service: for a fee, it mixed a bunch of people’s bitcoins up so that it was hard to figure out where any individual coins came from. It ran for ten years.
Identifying the person behind Bitcoin Fog serves as an illustrative example of how hard it is to be anonymous online in the face of a competent police investigation:
Most remarkable, however, is the IRS’s account of tracking down Sterlingov using the very same sort of blockchain analysis that his own service was meant to defeat. The complaint outlines how Sterlingov allegedly paid for the server hosting of Bitcoin Fog at one point in 2011 using the now-defunct digital currency Liberty Reserve. It goes on to show the blockchain evidence that identifies Sterlingov’s purchase of that Liberty Reserve currency with bitcoins: He first exchanged euros for the bitcoins on the early cryptocurrency exchange Mt. Gox, then moved those bitcoins through several subsequent addresses, and finally traded them on another currency exchange for the Liberty Reserve funds he’d use to set up Bitcoin Fog’s domain.
Based on tracing those financial transactions, the IRS says, it then identified Mt. Gox accounts that used Sterlingov’s home address and phone number, and even a Google account that included a Russian-language document on its Google Drive offering instructions for how to obscure Bitcoin payments. That document described exactly the steps Sterlingov allegedly took to buy the Liberty Reserve funds he’d used.
