Binance under scrutiny over response to South Korean police request in Upbit breach case

South Korean police asked Binance to freeze Solana tokens linked to the Upbit breach on Nov. 27. Binance reportedly froze about $55,000 after a delay of roughly 15 hours. The Upbit breach involved unauthorised Solana-based withdrawals worth about $36 million.

South Korean authorities are examining how overseas crypto platforms respond to urgent law enforcement requests after new details emerged about Binance’s handling of a police freeze request linked to a security breach at Upbit.

The case has become a reference point for how quickly stolen digital assets can be contained once they leave domestic exchanges and move across borders.

AIs Exploiting Smart Contracts

I have long maintained that smart contracts are a dumb idea: that a human process is actually a security feature.

Here’s some interesting research on training AIs to automatically exploit smart contracts:

AI models are increasingly good at cyber tasks, as we’ve written about before. But what is the economic impact of these capabilities? In a recent MATS and Anthropic Fellows project, our scholars investigated this question by evaluating AI agents’ ability to exploit smart contracts on Smart CONtracts Exploitation benchmark (SCONE-bench)­a new benchmark they built comprising 405 contracts that were actually exploited between 2020 and 2025. On contracts exploited after the...

Purism Liberty Phone Exists vs. Delayed T1 Phone

NBC News reports that Trump Mobile customers have been waiting months for a promised ‘Made in the USA’ smartphone, originally announced for August delivery. The T1 phone was marketed as domestically produced, but delays and vague updates have raised skepticism. References to ‘Made in the USA’ have been removed from the company’s site, and leaked images suggest the device resembles existing Chinese-made models. This situation underscores the complexity of building smartphones in America without established infrastructure.

FBI Warns of Fake Video Scams

The FBI is warning of AI-assisted fake kidnapping scams:

Criminal actors typically will contact their victims through text message claiming they have kidnapped their loved one and demand a ransom be paid for their release. Oftentimes, the criminal actor will express significant claims of violence towards the loved one if the ransom is not paid immediately. The criminal actor will then send what appears to be a genuine photo or video of the victim’s loved one, which upon close inspection often reveals inaccuracies when compared to confirmed photos of the loved one. Examples of these inaccuracies include missing tattoos or...

AI vs. Human Drivers

Two competing arguments are making the rounds. The first is by a neurosurgeon in the New York Times. In an op-ed that honestly sounds like it was paid for by Waymo, the author calls driverless cars a “public health breakthrough”:

In medical research, there’s a practice of ending a study early when the results are too striking to ignore. We stop when there is unexpected harm. We also stop for overwhelming benefit, when a treatment is working so well that it would be unethical to continue giving anyone a placebo. When an intervention works this clearly, you change what you do.

There’s...
