This Thin and Light Asus Laptop Checks Every Box and Then Some

a5tatuib0g0bmfcfjrji.jpg

Every time a new thin, light laptop comes across my desk, I become more resigned to the fact that it’s time to move on from my now 5-year-old gaming laptop. I’m careening toward middle age, and I need a practical, portable machine to keep my hips in their sockets. (I feel old, OK?) My desktop will always have a…

New Spectre attack once again sends Intel and AMD scrambling for a fix

Since 2018, an almost endless series of attacks broadly known as Spectre has kept Intel and AMD scrambling to develop defenses to mitigate vulnerabilities that allow malware to pluck passwords and other sensitive information directly out of silicon. Now, researchers say they’ve devised a new attack that breaks most—if not all—of those on-chip defenses.

Spectre got its name for its abuse of speculative execution, a feature in virtually all modern CPUs that predicts the future instructions the CPUs might receive and then follows a path that the instructions are likely to follow. By using code that forces a CPU to execute instructions along the wrong path, Spectre can extract confidential data that would have been accessed had the CPU continued down that wrong path. These exploits are known as transient executions.

“Dangerous implications”

Since Spectre was first described in 2018, new variants have surfaced almost every month. In many cases, the new variants have required chipmakers to develop new or augmented defenses to mitigate the attacks.
