Cloudy with a Chance of Hacks: Researchers Unveil How to Leak Data from Public Clouds
Academic researchers have proven that the L1TF vulnerability, thought to be a relic of the past, is back for an encore performance in public clouds. By combining it with half-Spectre, they’ve managed to leak sensitive data faster than a cat meme can go viral. Google Cloud even rewarded them with a hefty $151,515!
Hot Take:
Who knew CPUs could be such gossip queens? Looks like they’ve spilled the beans on virtual machines in the public cloud, and now everyone wants a piece of the juicy intel (pun intended). Move over, social media influencers—there’s a new leak in town, and it’s coming straight from inside the cloud!
Key Points:
- Researchers combined L1TF and half-Spectre vulnerabilities to leak data from public cloud environments.
- The attack, dubbed “L1TF Reloaded,” bypasses standard software mitigations.
- Execution was successful on Google Cloud, leaking sensitive information like TLS keys.
- The technique exploits the CPU’s transient execution to access unauthorized data.
- Google rewarded the researchers for their discovery, emphasizing the importance of cloud security defenses.
