An indictment from the US Department of Justice may have solved the mystery of how disgraced cryptocurrency exchange FTX lost over $400 million in crypto. The indictment, filed last week, alleges that three individuals used a SIM-swapping attack to steal hundreds of millions in virtual currency from an unnamed company. The timing and the amount stolen coincides with FTX’s theft. Meanwhile, in a letter obtained by WIRED this week, seven lawmakers have demanded the DOJ stop funding biased and inaccurate predictive policing tools until the agency has a way to ensure law enforcement won’t use them in a way that has a “discriminatory impact.”

In Florida, prosecutors say a 17-year-old named Alan Winston Filion is responsible for hundreds of swatting attacks around the United States. The news of his arrest was first reported by WIRED days before law enforcement made it public. It was the culmination of a multi-agency manhunt to piece together a trail of digital breadcrumbs left by the teenager. In Ukraine, unmanned aerial vehicles have been powerful tools since the Russian invasion began in February 2022. But as the war rages on, another kind of unmanned robot has increasingly appeared on the front-lines: the unmanned ground vehicle, or UGV.

For months lawyers affiliated with an India based hacker-for-hire firm called Appin Technology have used legal threats to censor reporting about the company’s alleged cyber mercenary past. The EFF, Techdirt, MuckRock, and DDoSecrets are now pushing back, publicly sharing details for the first time about the firm’s efforts to remove content from the web. It’s a dangerous world out there, so we’ve also got a list of some major patches issued in January that you can use to update your devices to keep them secure.

And there’s more. Each week, we highlight the news we didn’t cover in-depth ourselves. Click on the headlines below to read the full stories. And stay safe out there.

For years Western security officials have warned about the threat of China collecting data about millions of people and the country’s hackers infiltrating sensitive systems. This week, Federal Bureau of Investigation director Christopher Wray said hackers affiliated with the Chinese Communist Party are constantly targeting US critical infrastructure, such as water treatment plants, the electrical grid, and oil and gas pipelines. Wray’s testimony, at a House subcommittee on China, came as the FBI also revealed it removed malware from hundreds of routers in people’s homes and offices that had been planted by the Chinese hacking group Volt Typhoon.

“China’s hackers are positioning on American infrastructure in preparation to wreak havoc and cause real-world harm to American citizens and communities,” Wray said in the public appearance. “Low blows against civilians are part of China’s plan.” The FBI director added that China has a bigger hacking operation than “every other major nation combined,” and claimed that if all of the FBI’s cyber-focused agents were assigned to work on issues related to China, they would still be outnumbered “by at least 50 to 1.”

While concerns about the scale of China’s espionage and cyber operations aren’t new, the US intelligence community has been increasingly vocal and worried about critical infrastructure being targeted by Volt Typhoon and other groups. “The threat is extremely sophisticated and pervasive,” NSA officials warned in November. In May 2023, Microsoft revealed it had been tracking Volt Typhoon intrusions at communications and transportation infrastructure, among other critical infrastructure, in US states and Guam.

The FBI and DOJ, also revealed this week that they remotely removed the KV Botnet malware from hundreds of routers infected by Volt Typhoon. The impacted routers, from Cisco and Netgear, were mostly at the end of their life, but were being used as part of wider operations. “​​The Volt Typhoon malware enabled China to hide, among other things, pre-operational reconnaissance and network exploitation against critical infrastructure like our communications, energy, transportation, and water sectors,” Wray said. It isn’t the first time US officials have obtained a court order to remotely wipe devices infected by hackers, but the move is still rare.

Since the first cryptocurrencies emerged more than a decade ago, there has been the assumption that the blockchain-based digital currencies are anonymous and untraceable. They are, in fact, very traceable. Researchers have shown how people can be linked to the transactions they make and law enforcement have used the techniques to help bust illicit dark web markets and catch pedophiles. There are, however, still some privacy-focused cryptocurrencies that appear to be less traceable than Bitcoin. This includes Monero, which is increasingly being adopted by sellers of child sexual abuse materials.

This week investigators in Finland said Moreno-tracing helped reveal the identity of a hacker who allegedly attacked psychotherapy company Vastaamo in 2020, stealing thousands of patient records and threatening to leak them unless people paid a ransom. Investigators from the Finnish National Bureau of Investigation claim they used heuristic analysis to infer where funds were moved to. The investigators did not reveal the full methods of how they allegedly traced the Monero payments, however, they add to the growing body of evidence that cryptocurrency tracing firms and investigators may be able to track the currency.

Planes flying over Europe have faced a spike in accuracy issues with GPS systems used for navigation in recent months. The head of Estonia’s Defense Forces has claimed that Russia is likely the source of this interference, according to an interview with Bloomberg. “Someone is causing it, and we think it’s Russia,” Martin Herem told the publication, adding that Russia may be testing its electronic warfare capabilities and “learning” the most effective tactics. Across Europe, and particularly the Baltics region, there has been a reported increase in GPS jamming, with Finland reporting large interferences in December and pilots repeatedly reporting issues with their navigation systems.

In 2017, the Vault 7 leaks exposed some of the CIA’s most sophisticated hacking tools, including how the agency could compromise routers, phones, PC, and TVs. Joshua Schulte, a former CIA engineer in the agency’s Operations Support Branch who prosecutors identified as being behind the data breach and responsible for leaking the materials to Wikileaks, was convicted in numerous trials in recent years. Schulte, who denied the allegations, has been sentenced to 40 years in prison for the espionage and also for possessing thousands of child abuse images. Judge Jesse Furman, sentencing Schulte, said he had caused “untold damage to national security.” In June 2022, The New Yorker published this comprehensive investigation into the data breach and Schulte’s troubled history working at the agency.
