The US has returned $154 million in bitcoins stolen by a Sony employee.
However, on December 1, following an investigation in collaboration with Japanese law enforcement authorities, the FBI seized the 3879.16242937 BTC in Ishii’s wallet after obtaining the private key, which made it possible to transfer all the bitcoins to the FBI’s bitcoin wallet.

From Ontario and not surprising:
Since September 2021, officers have investigated five incidents where suspects have placed small tracking devices on high-end vehicles so they can later locate and steal them. Brand name “air tags” are placed in out-of-sight areas of the target vehicles when they are parked in public places like malls or parking lots. Thieves then track the targeted vehicles to the victim’s residence, where they are stolen from the driveway.
Thieves typically use tools like screwdrivers to enter the vehicles through the driver or passenger door, while ensuring not to set off alarms. Once inside, an electronic device, typically used by mechanics to reprogram the factory setting, is connected to the onboard diagnostics port below the dashboard and programs the vehicle to accept a key the thieves have brought with them. Once the new key is programmed, the vehicle will start and the thieves drive it away.
I’m not sure if there’s anything that can be done:
When Apple first released AirTags earlier this year, concerns immediately sprung up about nefarious use cases for the covert trackers. Apple responded with a slew of anti-stalking measures, but those are more intended for keeping people safe than cars. An AirTag away from its owner will sound an alarm, letting anyone nearby know that it’s been left behind, but it can take up to 24 hours for that alarm to go off — more than enough time to nab a car in the dead of night.

A hacker stole $31 million from the blockchain company MonoX Finance , by exploiting a bug in software the service uses to draft smart contracts.
Specifically, the hack used the same token as both the tokenIn and tokenOut, which are methods for exchanging the value of one token for another. MonoX updates prices after each swap by calculating new prices for both tokens. When the swap is completed, the price of tokenInthat is, the token sent by the userdecreases and the price of tokenOutor the token received by the userincreases.
By using the same token for both tokenIn and tokenOut, the hacker greatly inflated the price of the MONO token because the updating of the tokenOut overwrote the price update of the tokenIn. The hacker then exchanged the token for $31 million worth of tokens on the Ethereum and Polygon blockchains.
The article goes on to talk about how common these sorts of attacks are. The basic problem is that the code is the ultimate authority — there is no adjudication protocol — so if there’s a vulnerability in the code, there is no recourse. And, of course, there are lots of vulnerabilities in code.
To me, this is reason enough never to use smart contracts for anything important. Human-based adjudication systems are not useless pre-Internet human baggage, they’re vital.

Good article about the current state of cryptocurrency forensics.

MalwareBytes is reporting a weird software credit card skimmer. It harvests credit card data stolen by another, different skimmer:
Even though spotting multiple card skimmer scripts on the same online shop is not unheard of, this one stood out due to its highly specialized nature.
“The threat actors devised a version of their script that is aware of sites already injected with a Magento 1 skimmer,” Malwarebytes’ Head of Threat Intelligence Jérôme Segura explains in a report shared in advance with Bleeping Computer.
“That second skimmer will simply harvest credit card details from the already existing fake form injected by the previous attackers.”

Insider data theft:
Dutch police have arrested two individuals on Friday for allegedly selling data from the Dutch health ministry’s COVID-19 systems on the criminal underground.
According to Verlaan, the two suspects worked in DDG call centers, where they had access to official Dutch government COVID-19 systems and databases.
They were working from home:
“Because people are working from home, they can easily take photos of their screens. This is one of the issues when your administrative staff is working from home,” Victor Gevers, Chair of the Dutch Institute for Vulnerability Disclosure, told ZDNet in an interview today.
All of this remote call-center work brings with it additional risks.

The Finnish psychotherapy clinic Vastaamo was the victim of a data breach and theft. The criminals tried extorting money from the clinic. When that failed, they started extorting money from the patients:
Neither the company nor Finnish investigators have released many details about the nature of the breach, but reports say the attackers initially sought a payment of about 450,000 euros to protect about 40,000 patient records. The company reportedly did not pay up. Given the scale of the attack and the sensitive nature of the stolen data, the case has become a national story in Finland. Globally, attacks on health care organizations have escalated as cybercriminals look for higher-value targets.
Vastaamo said customers and employees had “personally been victims of extortion” in the case. Reports say that on Oct. 21 and Oct. 22, the cybercriminals began posting batches of about 100 patient records on the dark web and allowing people to pay about 500 euros to have their information taken down.

Greg Priore, the person in charge of the rare book room at the Carnegie Library, stole from it for almost two decades before getting caught.
It’s a perennial problem: trusted insiders have to be trusted.

South Africa’s Postbank experienced a catastrophic security failure. The bank’s master PIN key was stolen, forcing it to cancel and replace 12 million bank cards.
The breach resulted from the printing of the bank’s encrypted master key in plain, unencrypted digital language at the Postbank’s old data centre in the Pretoria city centre.
According to a number of internal Postbank reports, which the Sunday Times obtained, the master key was then stolen by employees.
One of the reports said that the cards would cost about R1bn to replace. The master key, a 36-digit code, allows anyone who has it to gain unfettered access to the bank’s systems, and allows them to read and rewrite account balances, and change information and data on any of the bank’s 12-million cards.
The bank lost $3.2 million in fraudulent transactions before the theft was discovered. Replacing all the cards will cost an estimated $58 million.

BusKill is designed to wipe your laptop (Linux only) if it is snatched from you in a public place:
The idea is to connect the BusKill cable to your Linux laptop on one end, and to your belt, on the other end. When someone yanks your laptop from your lap or table, the USB cable disconnects from the laptop and triggers a udev script [1, 2, 3] that executes a series of preset operations.
These can be something as simple as activating your screensaver or shutting down your device (forcing the thief to bypass your laptop’s authentication mechanism before accessing any data), but the script can also be configured to wipe the device or delete certain folders (to prevent thieves from retrieving any sensitive data or accessing secure business backends).
Clever idea, but I — and my guess is most people — would be much more likely to stand up from the table, forgetting that the cable was attached, and yanking it out. My problem with pretty much all systems like this is the likelihood of false alarms.
EDITED TO ADD (1/14): There are Bluetooth devices that will automatically encrypt a laptop when the device isn’t in proximity. That’s a much better interface than a cable.
