A security researcher has discovered secret hardware backdoors in RFID key cards manufactured by a major Chinese company.
The backdoors can allow threat actors to clone affected smart cards within minutes and access secure areas.
They impact smart cards manufactured by Chinese company Shanghai Fudan Microelectronics that were built using MIFARE Classic chips from NXP.
The chips have been on the market since 1994 and have been widely used over the past decades to create smart key cards and access badges in hotels, banks, government buildings, factories, and many other places.

Because they've been on the market for so long, they also have not escaped the prying eyes of the cybersecurity community, which has found several ways to break their encryption and clone MIRAGE-based cards—such as the Darkside, Nested Authentication, Hardnested, or the Static Nested attacks.
Over the years, vendors have developed improved versions of their smart cards that shipped with various improvements designed to boost security and prevent some of the discovered attacks.
Two of the most popular card designs are the FM11RF08 and FM11RF08S variants—where the S stands for "Security improved version."
But in a paper published last week, Quarkslab's Philippe Teuwen says that while researching FM11RF08S cards, he found what proved to be a secret backdoor baked inside Fudan cards.
He discovered the backdoor while fuzzing the card's command sets and noticed that the card was answering to undocumented instructions on a specific range.
"Apparently, all FM11RF08S implement a backdoor authentication command with a unique key for the entire production. And we broke it."
For Fudan FM11RF08S cards, that key was A396EFA4E24F.
Taking his research further, he also found a similar universal backdoor authentication key for the older FM11RF08 cards, which was A31667A8CEC1.
This one also impacted many other Fudan card models, such as the FM11RF32 and FM1208-10. It also impacted card models from Infineon and NXP, suggesting these companies had likely licensed card technology from the Chinese company.
According to Teuwen, the backdoor seems to go back as far as 2007, meaning that many access key cards distributed over the past 17 years can likely be cloned with physical access within seconds.
As it was pointed out in a previous paragraph, RF access cards based on MIFARE Classic were already considered insecure for a long time, but that was due to design errors and not a backdoor. Attackers would still have to waste minutes and physical resources to crack and dump a card's data in order to clone access keys configured on it.
An intentional backdoor puts these cards into a whole new threat matrix cell.
Breaches, hacks, and security incidents
Unicoin hack: A threat actor has gained access to the Google Workspace of cryptocurrency platform Unicoin and changed the passwords of all of its employees. The intrusion took place on August 9 and Unicoin says it was able to remove the hacker from its systems four days later on the 13th. Following the hack, Unicoin says it also discovered additional incidents in its environment, such as hacked accounts for some managers and a contractor who was using a forged identity. The company says no customer funds were stolen following the breach. [Additional coverage in The Record]
Trackimo hack: A hacker going by the name of Maia Arson Crimew says they gained access to the backend of GPS tracker vendor Trackimo. Crimew says the company's backend tool, named the Trackimo Troubleshooter, was using a simple password that was easy to guess. The tool contained debug information from all of the company's GPS devices, including information like customer names, emails, passwords, GPS coordinates, battery levels, and uptime information. Trackimo secured the system after Crimew's report.
Promises2Kids ransomware attack: After hitting Synnovis and crippling NHS operations and blood donations for months in the UK, the Qilin ransomware group has claimed an attack on Promises2Kids, a non-profit involved in child fostering in South California.

Vega hack: Ukraine's military intelligence agency GUR says it conducted an offensive cyber operation against a Russian organization involved in Russia's nuclear weapons program. The agency says the attack was conducted together with a hacktivist group named the BO Team and targeted the All-Russian Scientific Research Institute of Technical Physics (VNIITF) in Snezhinsk, Chelyabinsk. The GUR says it stole data on the institute's employees, nuclear plant, and sanctions evasion tactics. Officials say they also wiped 10 servers and more than 1,100 switches from Vega, the institute's internet service provider. According to NetBlocks, the attack also left a large part of the Snezhinsk city without internet access. Snezhinsk is one of Russia's ten infamous "nuclear cities"—cities dedicated to nuclear research that had no formal name and were not listed on any map.

Government, politics, and policy
House asks for investigation into Chinese WiFi routers: The US House Committee on CCP has asked the Commerce Department to investigate Chinese WiFi router maker TP-Link. Officials say the proliferation of the company's routers in the US is creating a potential national security risk. The Committee says the high number of vulnerabilities in TP-Link products could allow state-sponsored hackers to easily breach US infrastructure. Officials also cited China's draconian national security laws that could also force TP-Link to hand over data on US citizens to the Chinese state. The Committee's warning comes after CISA and many cybersecurity firms warned that Chinese state-sponsored hackers are using botnets made of home routers to hide operations against US and Western targets.
Ransomware incidents during the election: The FBI published a public service announcement last week reiterating that even if there are disruptions to the US election infrastructure during the voting period this fall, the vote itself is safe and will take place regardless.
"Any successful ransomware attack on election infrastructure tracked by FBI and CISA has remained localized and successfully managed with minimal disruption to election operations and no impact on the security and accuracy of ballot casting or tabulation processes or systems."

Cybercrime and threat intel
Extortionist charged: US officials have charged a New Jersey man with hacking and extorting his employer at the end of last year. According to court documents, Daniel Rhyne abused his position as core infrastructure engineer to create a secret virtual machine on his company's network. Rhyne allegedly used this VM to run automated scripts that changed the passwords of employee accounts, deleted backups, and shut down his employer's servers. He then used a new email account to demand a $750,000 ransom to be paid within a week. The FBI says it tracked the attack to Rhyne after they linked the hidden VM to one of his laptops.
