![]() ![]() I hate to speak so crudely, but yeah, we are screwed. To truly stop Spectre, all computers need to be replaced - think about that for a moment. Pretty much every computer and device from the last 20 years is susceptible to Spectre, and that includes servers and cloud computers. While you can fight against malware that leverages Spectre, it can only be eliminated by redesigning the way modern processors work, and that is very bad. The bad news? You can never truly fix Spectre on existing hardware. ![]() Linux kernel 4.14.11 patches this vulnerability and is available now. In fact, Microsoft is readying a fix for Windows 10, while macOS is already partly protected as per the most recent High Sierra version. The good news is, software patches for Windows, Mac, and Linux can stop Meltdown. ![]() However, it is possible to prevent specific known exploits based on Spectre through software patches. Spectre is harder to exploit than Meltdown, but it is also harder to mitigate. In fact, the safety checks of said best practices actually increase the attack surface and may make applications more susceptible to Spectre It allows an attacker to trick error-free programs, which follow best practices, into leaking their secrets. Spectre breaks the isolation between different applications. Luckily, there are software patches against Meltdown. This applies both to personal computers as well as cloud infrastructure. If your computer has a vulnerable processor and runs an unpatched operating system, it is not safe to work with sensitive information without the chance of leaking the information. This attack allows a program to access the memory, and thus also the secrets, of other programs and the operating system. Meltdown breaks the most fundamental isolation between user applications and the operating system. Spooky! The official (simplified) explanation of each bug is listed below. Meltdown is represented by a melting shield, while Spectre is a ghost wielding a stick. What's the worst that could happen? Well, your data and passwords could leak and you are almost powerless to stop it.Īs is the trend nowadays, these vulnerabilities have cool names, their own website, and of course, fancy logos. Seriously, folks, this is very bad - it is like the computing apocalypse. This vulnerability is called "Spectre," and it has the potential to put the entire technology industry into a tailspin. You see, yet another vulnerability has been revealed that impacts all modern processors, such as those from Intel, AMD, and yeah, even ARM chips. If you have an AMD processor, you are safe, right? Yes, but not really. ![]()
