How does TLBleed abuse the Hyper-Threading feature in Intel chips?
TLBleed exploits use Intel’s HTT feature to leak data. Learn how hackers could use this new side-channel attack to obtain sensitive memory information.

TLBleed attack can extract signing keys, but exploit is difficult
Researchers discovered a side-channel attack, named TLBleed, that abuses the Hyper-Threading feature of Intel chips. But Intel said customers should be immune, even without a patch.

Virtualization isn’t perfect, but SLAT minimizes hypervisor overhead
Second Level Address Translation can help reduce hypervisor overhead, but you may need to check for SLAT support on existing systems and enable support in the BIOS.

CPU features you need for virtualization
CPU features are critical to hypervisor performance. Choosing the right hardware can ensure your virtualized workloads run at peak performance.

Can a new encryption trick prevent reverse engineering?
Learn about Hardened Anti-Reverse Engineering System, or HARES, which cannot exactly prevent reverse engineering, but makes it a little tougher for attackers to complete.
