Everyone is writing about an interagency and international report on Chinese hacking of US critical infrastructure.
Lots of interesting details about how the group, called Volt Typhoon, accesses target networks and evades detection.
Interesting essay on the poisoning of LLMs—ChatGPT in particular:
Given that we’ve known about model poisoning for years, and given the strong incentives the black-hat SEO crowd has to manipulate results, it’s entirely possible that bad actors have been poisoning ChatGPT for months. We don’t know because OpenAI doesn’t talk about their processes, how they validate the prompts they use for training, how they vet their training data set, or how they fine-tune ChatGPT. Their secrecy means we don’t know if ChatGPT has been safely managed.
They’ll also have to update their training data set at some point. They can’t leave their models stuck in 2021 forever.
Once they do update it, we only have their word—pinky-swear promises—that they’ve done a good enough job of filtering out keyword manipulations and other training data attacks, something that the AI researcher El Mahdi El Mhamdi posited is mathematically impossible in a paper he worked on while he was at Google.
A Peruvian oversight law has the opposite effect:
Peru in 2020 began requiring any foreign fishing boat entering its ports to use a vessel monitoring system allowing its activities to be tracked in real time 24 hours a day. The equipment, which tracks a vessel’s geographic position and fishing activity through a proprietary satellite communication system, sought to provide authorities with visibility into several hundred Chinese squid vessels that every year amass off the west coast of South America.
[…]
Instead of increasing oversight, the new Peruvian regulations appear to have driven Chinese ships away from the country’s ports—and kept crews made up of impoverished Filipinos and Indonesians at sea for longer periods, exposing them to abuse, according to new research published by Peruvian fishing consultancy Artisonal.
Two things to note here. One is that the Peruvian law was easy to hack, which China promptly did. The second is that no nation-state has the proper regulatory footprint to manage the world’s oceans. These are global issues, and need global solutions. Of course, our current society is terrible at global solutions—to anything.
As usual, you can also use this squid post to talk about the security stories in the news that I haven’t covered.
Read my blog posting guidelines here.
Reuters is reporting that the FBI “had identified and disabled malware wielded by Russia’s FSB security service against an undisclosed number of American computers, a move they hoped would deal a death blow to one of Russia’s leading cyber spying programs.”
The headline says that the FBI “sabotaged” the malware, which seems to be wrong.
Presumably we will learn more soon.
EDITED TO ADD: New York Times story.
EDITED TO ADD: Maybe “sabotaged” is the right word. The FBI hacked the malware so that it disabled itself.
Despite the bravado of its developers, Snake is among the most sophisticated pieces of malware ever found, the FBI said. The modular design, custom encryption layers, and high-caliber quality of the code base have made it hard if not impossible for antivirus software to detect. As FBI agents continued to monitor Snake, however, they slowly uncovered some surprising weaknesses. For one, there was a critical cryptographic key with a prime length of just 128 bits, making it vulnerable to factoring attacks that expose the secret key. This weak key was used in Diffie-Hellman key exchanges that allowed each infected machine to have a unique key when communicating with another machine.
At DEF CON this year, Anthropic, Google, Hugging Face, Microsoft, NVIDIA, OpenAI and Stability AI will all open up their models for attack.
The DEF CON event will rely on an evaluation platform developed by Scale AI, a California company that produces training for AI applications. Participants will be given laptops to use to attack the models. Any bugs discovered will be disclosed using industry-standard responsible disclosure practices.
New reporting from Wired reveals that the Department of Justice detected the SolarWinds attack six months before Mandiant detected it in December 2020, but didn’t realize what it detected—and so ignored it.
WIRED can now confirm that the operation was actually discovered by the DOJ six months earlier, in late May 2020—but the scale and significance of the breach wasn’t immediately apparent. Suspicions were triggered when the department detected unusual traffic emanating from one of its servers that was running a trial version of the Orion software suite made by SolarWinds, according to sources familiar with the incident. The software, used by system administrators to manage and configure networks, was communicating externally with an unfamiliar system on the internet. The DOJ asked the security firm Mandiant to help determine whether the server had been hacked. It also engaged Microsoft, though it’s not clear why the software maker was also brought onto the investigation.
[…]
Investigators suspected the hackers had breached the DOJ server directly, possibly by exploiting a vulnerability in the Orion software. They reached out to SolarWinds to assist with the inquiry, but the company’s engineers were unable to find a vulnerability in their code. In July 2020, with the mystery still unresolved, communication between investigators and SolarWinds stopped. A month later, the DOJ purchased the Orion system, suggesting that the department was satisfied that there was no further threat posed by the Orion suite, the sources say.
EDITED TO ADD (5/4): More details about the SolarWinds attack from Wired.com.
My latest book, A Hacker’s Mind, is filled with stories about the rich and powerful hacking systems, but it was hard to find stories of the hacking by the less powerful. Here’s one I just found. An article on how layoffs at big companies work inadvertently suggests an employee hack to avoid being fired:
…software performs a statistical analysis during terminations to see if certain groups are adversely affected, said such reviews can uncover other problems. On a list of layoff candidates, a company might find it is about to fire inadvertently an employee who previously opened a complaint against a manager—a move that could be seen as retaliation, she said.
So if you’re at a large company and there are rumors of layoffs, go to HR and initiate a complaint against a manager. It’ll protect you from being laid off.
My latest book, A Hacker’s Mind, has a lot of sports stories. Sports are filled with hacks, as players look for every possible advantage that doesn’t explicitly break the rules. Here’s an example from pickleball, which nicely explains the dilemma between hacking as a subversion and hacking as innovation:
Some might consider these actions cheating, while the acting player would argue that there was no rule that said the action couldn’t be performed. So, how do we address these situations, and close those loopholes? We make new rules that specifically address the loophole action. And the rules book gets longer, and the cycle continues with new loopholes identified, and new rules to prohibit that particular action in the future.
Alternatively, sometimes an action taken as a result of an identified loophole which is not deemed as harmful to the integrity of the game or sportsmanship, becomes part of the game. Ernie Perry found a loophole, and his shot, appropriately named the “Ernie shot,” became part of the game. He realized that by jumping completely over the corner of the NVZ, without breaking any of the NVZ rules, he could volley the ball, making contact closer to the net, usually surprising the opponent, and often winning the rally with an un-returnable shot. He found a loophole, and in this case, it became a very popular and exciting shot to execute and to watch!
I don’t understand pickleball at all, so that explanation doesn’t make a lot of sense to me. (I watched a video explaining the shot; that helped somewhat.) But it looks like an excellent example.
The blog post also links to a 2010 paper that I wish I’d known about when I was writing my book: “Loophole ethics in sports,” by Øyvind Kvalnes and Liv Birgitte Hemmestad:
Abstract: Ethical challenges in sports occur when the practitioners are caught between the will to win and the overall task of staying within the realm of acceptable values and virtues. One way to prepare for these challenges is to formulate comprehensive and specific rules of acceptable conduct. In this paper we will draw attention to one serious problem with such a rule-based approach. It may inadvertently encourage what we will call loophole ethics, an attitude where every action that is not explicitly defined as wrong, will be seen as a viable option. Detailed codes of conduct leave little room for personal judgement, and instead promote a loophole mentality. We argue that loophole ethics can be avoided by operating with only a limited set of general principles, thus leaving more space for personal judgement and wisdom.
EDITED TO ADD (5/12): Here’s an eleven-second video that explains the Erne (or Ernie).
Here’s a religious hack:
You want to commit suicide, but it’s a mortal sin: your soul goes straight to hell, forever. So what you do is murder someone. That will get you executed, but if you confess your sins to a priest beforehand you avoid hell. Problem solved.
This was actually a problem in the 17th and 18th centuries in Northern Europe, particularly Denmark. And it remained a problem until capital punishment was abolished for murder.
It’s a clever hack. I didn’t learn about it in time to put it in my book, A Hacker’s Mind, but I have several other good hacks of religious rules.
Car thieves are injecting malicious software into a car’s network through wires in the headlights (or taillights) that fool the car into believing that the electronic key is nearby.
