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 … Read More “On the Poisoning of LLMs” »

Georgetown has a new report on the highly secretive bulk surveillance activities of ICE in the US: When you think about government surveillance in the United States, you likely think of the National Security Agency or the FBI. You might even think of a powerful police agency, such as the New York Police Department. But … Read More “ICE Is a Domestic Surveillance Agency” »

Puerto Rico is considered allowing for Internet voting. I have joined a group of security experts in a letter opposing the bill. Cybersecurity experts agree that under current technology, no practically proven method exists to securely, verifiably, or privately return voted materials over the internet. That means that votes could be manipulated or deleted on … Read More “Internet Voting in Puerto Rico” »

This is not surprising: This year, I bought two more machines to see if security had improved. To my dismay, I discovered that the newer model machines — those that were used in the 2016 election — are running Windows CE and have USB ports, along with other components, that make them even easier to … Read More “Buying Used Voting Machines on eBay” »

BoingBoing has the story. I have never quite trusted the idea of a warrant canary. But here it seems to have worked. (Presumably, if SpiderOak wanted to replace the warrant canary with a transparency report, they would have written something explaining their decision. To have it simply disappear is what we would expect if SpiderOak … Read More “SpiderOak’s Warrant Canary Died” »

Extracting Secrets from Machine Learning Systems

This is fascinating research about how the underlying training data for a machine-learning system can be inadvertently exposed. Basically, if a machine-learning system trains on a dataset that contains secret information, in some cases an attacker can query the system to extract that secret information. My guess is that there is a lot more research … Read More “Extracting Secrets from Machine Learning Systems” »

This story of leaked Australian government secrets is unlike any other I’ve heard: It begins at a second-hand shop in Canberra, where ex-government furniture is sold off cheaply. The deals can be even cheaper when the items in question are two heavy filing cabinets to which no-one can find the keys. They were purchased for … Read More “Cabinet of Secret Documents from Australia” »
