The Spectre of a Potential Security Meltdown

Spectre. Meltdown. These phrases sound like the titles of bad B-Movie action films. But they’re very much real. They’re the name of two massive CPU exploits that were uncovered over the past week (the first week of January 2018). Both are the biggest threats to processing hardware we’ve seen in a long time.

At their heart, both attacks take advantage of the fact that processors execute instructions speculatively. All modern processors perform speculative execution to a greater or lesser extent.

If it later turns out that the condition was false, the speculatively executed instructions are discarded as if they had no effect.

As usual, the government did its thing and recommended everyone kept their operating systems up to date and install strong anti-malware programmes to prevent such a crippling attack from happening again.

So. You’ve been responsible and followed these guidelines. That means you’re safe, right?

Reputation: The Phisher's Elixir

HTTPS certification. Anti-DDOS protections. CAPTCHA verification. All of these constantly evolving and expanding terms for protecting websites. It can get really frustrating having to keep up with the latest cyber-security techniques for your online services. Often an organisation’s website doesn’t collect any credentials, they don't have any payment info and in many cases, the site is simply a static representation of content that rarely changes.
