Citrix NetScaler Flaw Actively Exploited in Targeted Attacks
Researchers have uncovered a new Spectre v2 variant, called Branch Target Reuse (BTR), which can extract sensitive data, including root password hashes, from Intel machines running Linux in just minutes. This attack leverages a clever exploit that takes advantage of a desynchronization in modern CPUs.
Spectre Revives: Researchers Expose New JIT Engine Vulnerability
Meet Branch Target Reuse (BTR), a revived Spectre v2 attack that targets JIT engines, allowing hackers to exploit a major vulnerability in many CPUs that use speculative execution. This breakthrough lets attackers siphon sensitive data, like root password hashes, at alarming rates of up to 5.7 KB/sec.
New Spectre Variant BTR Exploits Linux Memory Despite Existing Defenses
Meet Branch Target Reuse (BTR), a new Spectre variant that cleverly exploits Linux memory, dodging existing defenses and leaving multiple JIT engines and the Linux kernel vulnerable. This sneaky attack uses a four-step sequence to tap into the CPU's indirect branch prediction structures.
New Spectre v2 Variant Exploits Linux Systems, Leaks Root Password Hashes
Researchers have uncovered a new Spectre v2 variant, dubbed Branch Target Reuse (BTR), that can exploit Linux systems and leak sensitive data, including root password hashes, in a matter of minutes. This attack can be executed in as little as 3-5 minutes, leaving systems vulnerable to potential breaches.
