A novel side-channel attack exploits radio signals emitted by random access memory in air-gapped computers, presenting a new threat to highly secure networks. One of the most effective ways to mitigate the risk is to cover sensitive machines with Faraday shielding.
Hundreds of laptop and server models from mainstream manufacturers are at risk of hacking that bypasses protections meant to ensure only trusted software can load during computer bootup, warn researchers from California supply chain startup Binarly.
Developers of a computer hardware project for stopping memory-based cyberattacks will soon release standards in a bid to overcome commercial hurdles to its adoption. Backers of the Capability Hardware Enhanced RISC Instructions, or CHERI, architecture hope it becomes more widely adopted.
A vulnerability in a common implementation of the firmware booting up desktop computers powered by Intel chips could allow attackers to obtain ongoing persistence, warn security researchers. The flaw is a buffer overflow vulnerability in the Phoenix Technologies SecureCore UEFI implementation.
Everfox's purchase of Garrison Technology is set to fortify its cybersecurity offerings, especially for government and critical infrastructure. The deal leverages Garrison's advanced hardware security technology to complement Everfox's existing capabilities in threat protection and insider risk.
A U.K. government official on Tuesday touted the potential of a processor designed to prevent memory-based cyberattacks even as he acknowledged commercial hurdles to its widespread adoption. The CHERI processor reduces attack surface, said John Goodacre.
Check Point Software Technologies has issued an emergency security update for its Security Gateways to fix a vulnerability being actively exploited in the wild to gain access to virtual private networks, as attackers' focus on attempting to exploit edge devices continues.
Research shows that attackers can physically extract secrets embedded in read-only memory on a shoestring budget. The equipment involves a polishing wheel, a jig and an optical microscope. The attack sounds impossible "until it's observed for real," said Tony Moor, an IOActive researcher.
Experts told ISMG that Chinese-made locks and commercial safes could pose national security risks when used by major U.S. businesses, institutions and the public - after a senator urged the government to update its publicly available information about the threat associated with Chinese-made safes.
The FDA's multifaceted approach to strengthening medical device security centers on several key areas, including enhanced regulatory oversight, industry collaboration and a recent organizational change that raises the profile of the agency's device work, said the FDA's Dr. Suzanne Schwartz.
Multiple vulnerabilities in a widely used open-source implementation of the UEFI specification allow attackers to introduce malware operating at the firmware level. The vulnerabilities mainly affect server machines in which a boot server delivers the operating system over the local network.
Hackers could use a firmware specification designed to flash a corporate logo during computer bootup to deliver a malicious payload that circumvents the industry standard for only loading trusted operating systems. The flaw stems from graphic image parsers embedded into system firmware.
Tens of thousands of knockoff Android products manufactured in China including TV streaming boxes reached consumers infected with malware, say cybersecurity researchers. Human Security says it uncovered a related operation that earned millions per month in an online advertising fraud scheme.
Medical device makers in their premarket submissions to the Food and Drug Administration under the agency's new "refuse to accept" policy for cybersecurity should pay close attention to details such as a product's software bill of materials and vulnerability management, said Jessica Wilkerson of FDA.
Dragos completed a Series D extension to help organizations address enhanced OT security requirements from regulators and cyber insurance providers. The money will allow Dragos to help EU businesses affected by updated cybersecurity directives requiring many smaller organizations to boost security.
