Breaches, hacks, and security incidents
Cyberattack on Iranian gas stations: A hacktivist group known as Predatory Sparrow has crippled the payment systems of gas stations across Iran. The incident is believed to have impacted more than 2,000 of the country's gas pumps (~70% of all pumps). Iranian officials have confirmed the incident and claimed the group is a front for Israeli and US cyber operations. BBC Persia claims the incident had a sprawling impact across the country, even days after the attack.
Ledger incident: A threat actor has compromised the npm account of a former Ledger employee and added malicious code to a Ledger SDK meant to connect web apps to the Ledger backend. The malicious code emptied Ledger wallets on websites that used the compromised SDK. Losses are estimated to be around $600,000.
Comcast hack: US telco Comcast says that hackers exploited the CitrixBleed vulnerability to breach one of its systems and steal the personal information of almost 36 million customers. Comcast says the hack took place between October 16 and October 19, 2023
Mr. Cooper hack: Mortgage and lending company Mr. Cooper says the ransomware attack that hit its IT systems at the end of October led to the theft of personal data of almost 14.7 million customers.
Coin Cloud hack: Hackers claim to have stolen the personal data of more than 300,000 customers of now-defunct Bitcoin ATM provider Coin Cloud. The hackers claim the data also includes more than 70,000 pictures of customers taken using the ATMs' cameras. [Additional coverage in TechCrunch]
MongoDB hack: The company behind the MongoDB database has announced a security breach of its corporate systems. The breach took place on December 13, and attackers appear to have gotten their hands on some customer data. MongoDB says they have not seen any unauthorized access to customer cloud environments (so far).
Kyivstar attribution: A hacking group named Solntsepek took credit for the attack that crippled Kyivstar, Ukraine's largest mobile telco. Ukrainian officials have attributed the attack to a hacking unit linked to Russia's military intelligence service GRU. Solntsepek has been previously linked to Sandworm.
OKX crypto-heist: A threat actor has stolen $2.7 million worth of crypto assets from OKX after they gained access to one of the platform's smart contracts keys.
Aurory crypto-heist: The Aurory cryptocurrency exchange has been hacked for $1.2 million worth of assets. The attacker apparently drained 80% of the company's liquidity pools. The platform has shut down all operations to investigate the hack.
NFT Trader crypto-heist: A threat actor exploited a vulnerability in the NFT Trader platform and stole $3 million worth of NFTs. NFT Trader blamed the bug on one of its third-party tools—like that would make their users feel better for some reason. The culprit seems to be the Flooring Protocol.
General tech and privacy
Windows Protected Print Mode: Microsoft has announced Windows Protected Print Mode (WPP), a more secure rewrite of the Windows print mode, the feature that allows the operating system to interact with printing devices. The new WPP mode was designed around the Internet Printing Protocol (IPP) and removes the need for third-party printing drivers, which are set to be phased out in the coming years. Microsoft says the new mode will be available for testing via Insiders builds and should work fine with most printers made in the last 10 years.
SAC in Windows 11: Germany's BSI has published a technical analysis of the new Smart App Control feature in Windows 11. It's in German, though.

[Additional coverage in The Verge]
Apple Stolen Device Protection: Apple is rolling out a new iOS feature named Stolen Device Protection that, when enabled, will require users to authenticate using Face ID or Touch ID before making changes to sensitive device settings. Besides requiring a facial scan or fingerprint scan, the Stolen Device Protection feature also adds a one-hour delay before changes are applied, allowing real device owners to still have access to their accounts and devices and prevent being locked out. [Additional coverage in MacRumors]
Passcode 5th Amendment: The Utah Supreme Court has ruled that suspects can refuse to hand over their phone passcode to police during an investigation.

Calisto APT: Sekoia has published its own (previously private) report on how they identified Russian individual Andrey Korinets as a member of the Calisto (Star Blizzard, Cold River) APT—recently sanctioned by the UK and charged by the US.
APT29 alert: CISA, the NCSC, and Poland's CERT team and SKW service warn that APT29 (linked to Russia's SVR intelligence agency) is exploiting a vulnerability (CVE-2023-42793) in JetBrains TeamCity servers for initial access to corporate and government systems. Fortinet and Logpoint also looked at the same attacks. According to the Shadowserver Foundation, more than 800 unpatched TeamCity servers were still connected online last week.
Volt Typhoon: Lumen has linked the new KV-botnet to the Volt Typhoon Chinese cyber-espionage group. Comprised of unpatched Cisco, Netgear, and Fortinet devices, the botnet has been used as a proxy and covert data transfer network.
"We assess from both our telemetry and open-source reporting, that the use of this botnet is limited to Chinese state-sponsored organizations. Thus far the victimology Black Lotus Labs has observed from the KV-cluster aligns primarily with a strategic interest in the Indo-Pacific region, having a particular focus on ISPs and government organizations. At least one user of the KV-cluster is Volt Typhoon, but Volt Typhoon is believed to operate over other obfuscation networks as well. We believe that it would be unlikely for the threat actor to repurpose this network to target lower valued networks and risk its discovery."
Chinese info-op targeting US: ASPI researchers have found a network of YouTube accounts pushing pro-Chinese and anti-US narratives and misinformation. Many of the videos used generative AI. The world of at-scale AI-generated misinformation is upon us.
