[4 minuty čtení] V tomto díle Postřehů se podíváme na nové informace k útoku na Ubiquiti, na pokus o kompromitaci repozitáře jazyka PHP, na nový spyware pro Android a na řadu dalších zajímavostí. Server krebsonsecurity.com zveřejnil závažné informace o úniku dat ze společnosti Ubiquiti. Podle zdroje serveru, který měl být u likvidace následků úniku dat se společnost snažila mlžit, aby snížila dopad na cenu akcií. Zdroj serveru prý obavy ohledně skutečných důsledků útoku probíral s „whistleblower hotline“ Ubiquiti i s evropským pověřencem pro ochranu dat.

[2 minuty čtení] Nadcházející verze PureOS umožní zašifrovat data v zařízení. Linuxová distribuce pro tablety JingOS byla portována na x86.

This past week AMD published a security analysis of AMD Zen 3's new Predictive Store Forwarding (PSF) functionality. In there they did acknowledge there is the possibility where bad PSF functionality could lead to a side-channel attack albeit the real-world exposure would be quite low. In any case they are allowing interested users to disable the Predictive Store Forwarding functionality, but what they didn't comment on in that paper was what performance overhead to expect if disabling PSF. So my Easter weekend turned into AMD Zen 3 PSF benchmarking.
