"Even though these new Nvidia drivers will halve the earning rate of the cybercriminals, the crooks aren't paying for the electricity, so any unlawfully mined crypto-coins are still essentially free money for them." "In the early days, it was possible to mine Bitcoin using the average computer CPU or a high-speed video processor card; however, today, mining for Bitcoin requires dedicated Bitcoin mining hardware to make it a profitable endeavor," according to the report.
Virtually all payment card terminals at self-checkout lanes now accept cards with a chip to be inserted into the machine. Most modern chip-based cards are significantly thinner than the average payment card was just a few years ago, but the design specifications for these terminals state that they must be able to allow the use of older, taller cards - such as those that still include embossing.
One of the first malware samples tailored to run natively on Apple's M1 chips has been discovered, suggesting a new development that indicates that bad actors have begun adapting malicious software to target the company's latest generation of Macs powered by its own processors. While the transition to Apple silicon has necessitated developers to build new versions of their apps to ensure better performance and compatibility, malware authors are now undertaking similar steps to build malware that are capable of executing natively on Apple's new M1 systems, according to macOS Security researcher Patrick Wardle.
A researcher has spotted the first piece of Mac malware that appears to have been created specifically for devices with Apple's recently introduced M1 chip. Wardle has developed several free and open source security tools for Macs, and came up with the idea to look for malware designed to run natively on M1 systems while rebuilding his tools for native M1 compatibility.
As a total sucker for anything skimming-related, I was interested to hear from a reader working security for a retail chain in the United States who recently found Bluetooth-enabled skimming devices placed over top of payment card terminals at several stores. Interestingly, these skimmers interfered with the terminal's ability to read chip-based cards, forcing customers to swipe the stripe instead. Here's a closer look at the electronic gear jammed into these overlay skimmers.
Following up on a disputed 2018 claim in its BusinessWeek publication that tiny spy chips were found on Supermicro server motherboards in 2015, Bloomberg on Friday doubled down by asserting that Supermicro's products were targeted by Chinese operatives for over a decade, that US intelligence officials have been aware of this, and that authorities kept this information quiet while crafting defenses in order to study the attack. The article - a follow-on to BusinessWeek's 2018 spy chip bombshell - cites three specific incidents: the 2010 discovery by the Defense Department that thousands of its computers were sending military network data to China due to code hidden in chips that handle the server startup process; Intel's discovery in 2014 that a Chinese hacking group penetrated its network via a server that fetched malware from an unidentified supplier's update site; and a 2015 warning issued by the FBI to multiple companies that Chinese agents had hidden an extra chip with backdoored code on one manufacturer's servers.
Intel and Cybereason have partnered to build anti-ransomware defenses into the chipmaker's newly announced 11th generation Core vPro business-class processors. The hardware-based security enhancements are baked into Intel's vPro platform via its Hardware Shield and Threat Detection Technology, enabling profiling and detection of ransomware and other threats that have an impact on the CPU performance.
The United States on Friday announced it has imposed export controls on 77 Chinese companies including the country's biggest chipmaker, SMIC, restricting its access to US technology over its alleged ties to China's military. The announcement in the final weeks of President Donald Trump's term comes after relations between Washington and Beijing soured under his administration, which saw the US start a trade war with China and expand its list of sanctioned entities to a few hundred Chinese companies and subsidiaries.
In a newly released working paper [PDF], "AIR-FI: Generating Covert Wi-Fi Signals from Air-Gapped Computers," Guri, head of research and development at Ben-Gurion University of the Negev, Israel's Cyber-Security Research Center, describes a technique for turning DDR SDRAM buses into transmitters that can spew sensitive data. It's a method for sending data via Wi-Fi signals when the target device doesn't have Wi-Fi capability.
Manufacturers can now embed certificates on chipsets prior to and during manufacturing, or directly to an edge device, for complete end-to-end device security. IoT Device Manager is built on DigiCert ONE, which enables rapid, automated PKI deployment as a customer-managed, on-premises or cloud solution, or managed by DigiCert for any environment.
