Microsoft and Google are jointly disclosing a new CPU security vulnerability that's similar to the Meltdown and Spectre flaws that were revealed earlier this year. Labelled Speculative Store Bypass (variant 4), the latest vulnerability is a similar exploit to Spectre and exploits speculative execution "that modern CPUs use. Browsers like Safari, Edge, and Chrome were all patched for Meltdown earlier this year, and Intel says these mitigations are also applicable to variant 4 and available for consumers to use today."
However, unlike Meltdown (and more similar to Spectre) this new vulnerability will also include firmware updates for CPUs that could affect performance. Intel has already delivered microcode updates for Speculative Store Bypass in beta form to OEMs, and the company expects them to be more broadly available in the coming weeks. The firmware updates will set the Speculative Store Bypass protection to off-by-default, ensuring that most people won’t see negative performance impacts.
This cat ain't going back in no bag anytime soon.
In an exclusive piece of research, Check Point Researchers have carried out a revealing investigation into North Korea's home-grown anti-virus software, SiliVaccine. One of several interesting factors is that a key component of SiliVaccine's code is a 10-year-old copy of one of Trend Micro's, a Japanese company, software components.
It also contained a piece of malware, so not much different from western anti-virus.
Once upon a time, a friend of mine accidentally took over thousands of computers. He had found a vulnerability in a piece of software and started playing with it. In the process, he figured out how to get total administration access over a network. He put it in a script, and ran it to see what would happen, then went to bed for about four hours. Next morning on the way to work he checked on it, and discovered he was now lord and master of about 50,000 computers. After nearly vomiting in fear he killed the whole thing and deleted all the files associated with it. In the end he said he threw the hard drive into a bonfire. I can't tell you who he is because he doesn't want to go to Federal prison, which is what could have happened if he'd told anyone that could do anything about the bug he'd found. Did that bug get fixed? Probably eventually, but not by my friend. This story isn't extraordinary at all. Spend much time in the hacker and security scene, you'll hear stories like this and worse.
It's hard to explain to regular people how much technology barely works, how much the infrastructure of our lives is held together by the IT equivalent of baling wire.
It's from 2014, but drop everything you're doing right now and read this. Go on. Don't put it off. Read it.
For the past few weeks, Forbes.com has been forcing visitors to disable ad blockers if they want to read its content. Visitors to the site with Adblock or uBlock enabled are told they must disable it if they wish to see any Forbes content. Thanks to Forbes' interstitial ad and quote of the day, Google caching doesn't capture data properly, either.
What sets Forbes apart, in this case, is that it didn't just force visitors to disable ad blocking - it actively served them malware as soon as they did. Details were captured by security researcher Brian Baskin, who screenshotted the process.
