Submission + - Blaming YouTube or the FBI for Yesterday's School Shooting Tragedy Is Wrong (

Lauren Weinstein writes: Before the blood had even dried in the classrooms of the Florida high school that was the venue for yet another mass shooting tragedy, authorities and politicians were out in force trying to assign blame everywhere.
That is, everywhere except for the fact that a youth too young to legally buy a handgun was able to legally buy an AR-15 assault-style weapon that he used to conduct his massacre.

Much of the misplaced blame this time is being lobbed at social media. The shooter, whom we now know had mental health problems but apparently had never been adjudicated as mentally ill, had a fairly rich social media presence, so the talking heads are blaming firms like YouTube and agencies like the FBI for not “connecting the dots” to prevent this attack.

Submission + - Researchers automate Spectre exploits, find additional side-channel

ffkom writes: In a new paper MeltdownPrime and SpectrePrime: Automatically-Synthesized Attacks Exploiting Invalidation-Based Coherence Protocols researchers describe an automated tool to write exploit code for Spectre-type attacks, tailored to different CPU architectures.

While using their tool, they also identified another side-channel that can be used for a new Spectre-variant they call "SpectrePrime": Instead of using speculative reads to fill caches, they use speculative writes that cause detectable changes to cache states, even when ultimately not executed.

In other news, one of the original Spectre researchers found Microsoft's compiler changes to mitigate Spectre type-1 attacks to be largely ineffective.

If you don't want ads, would you take them up on their offer?
