Meltdown and Spectre

Vulnerabilities in modern computers leak passwords and sensitive data.

The trouble makers


Am I affected by the vulnerability?

Most certainly, yes.
Can I detect if someone has exploited Meltdown or Spectre against me?

Probably not. The exploitation does not leave any traces in traditional log files.
Can my antivirus detect or block this attack?

While possible in theory, this is unlikely in practice. Unlike usual malware, Meltdown and Spectre are hard to distinguish from regular benign applications. However, your antivirus may detect malware which uses the attacks by comparing binaries after they become known.
What can be leaked?

If your system is affected, our proof-of-concept exploit can read the memory content of your computer. This may include passwords and sensitive data stored on the system.
Has Meltdown or Spectre been abused in the wild?

Is there a workaround/fix?

There are patches against Meltdown for Linux ( KPTI (formerly KAISER)), Windows, and OS X. There is also work to harden software against future exploitation of Spectre, respectively to patch software after exploitation through Spectre ( LLVM patch, MSVC, ARM speculation barrier header).
