CVE-2022-29900

In January 2018, the entire computer industry was put on alert by two new processor vulnerabilities dubbed Meltdown and Spectre that defeated the fundamental OS security boundaries separating kernel and user space memory. The flaws stemmed from a performance feature of modern CPUs known as speculative execution and mitigating them required one of the biggest patch coordination […]

Top Attacks and Breaches A callback phishing campaign has been observed targeting corporate networks while impersonating known cybersecurity companies – the emails mention an alleged threat in the target’s network, asking them to call the company […]

Vendors have started rolling out software updates to address the recently disclosed Retbleed speculative execution attack targeting Intel and AMD processors.

Researchers warn of a new vulnerability, dubbed Retbleed, that impacts multiple older AMD and Intel microprocessors. ETH Zurich researchers Johannes Wikner and Kaveh Razavi discovered a new vulnerability, dubbed Retbleed, that affects multiple older AMD and Intel microprocessors. An attacker can exploit the flaw to bypass current defenses and perform in Spectre-based attacks. The Retbleed vulnerability is tracked as […]

Researchers have discovered a new attack technique that exploits the speculative execution feature of modern CPUs to leak potentially sensitive information from the kernel’s memory. The attack circumvents some of the software defenses some operating systems put in place to prevent previous exploits of this nature. The attack, dubbed Retbleed by researchers from Swiss university […]

Researchers at Swiss university ETH Zurich have devised a new speculative execution attack that can lead to information leaks and works against both Intel and AMD processors.
