Hyper-threading je mrtvý, zámečky v prohlížečích nikoho nezajímají [LinuxDays]

Root.cz - 6. Říjen 2019 - 23:00
[17 minut čtení] O víkendu 5. a 6. října probíhal v Praze osmý ročník konference LinuxDays. Velká skupina přednášek se točila kolem bezpečnosti: chybné procesory, slabá hesla, webové prohlížeče a klonování SIM karet. Pokud náš procesor má několik jednotek, dokáže vykonávat instrukce napřed. Když se procesor dostane na rozcestí, třeba je tam podmíněný skok, musí se rozhodnout, jestli půjde tam nebo jinam. Proto potřebuje výsledek podmínky, která rozhoduje, kam se má vydat. Ta může být poměrně složitá, může potřebovat nějaký výpočet. Procesor ale tyhle výsledky ještě nemá. Může se buď zastavit a počkat nebo se některé právě nepoužívané jednotky mohou jedním směrem vydat.

Postřehy z bezpečnosti: zlomyslné obrázky

Root.cz - 6. Říjen 2019 - 23:00
[4 minuty čtení] Dnes se podíváme na poněkud zákeřné pohyblivé obrázky, na chybu v MTA Exim, povíme si o prakticky nezjistitelných možnostech sledování pomocí zpráv SMS, o botnetu šířícím se bez fyzických souborů s exploity a další. Na animované obrázky GIF lze dnes narazit prakticky všude: sociální sítě, emotikony, vtípky pro zasmání, reklama. Myslíte, že by pomocí nevinně vyhlížejícího obrázku s přáním „Šťastných a veselých“ někdo dokázal hacknout váš telefon? Teď už na tuto otázku známe překvapivou odpověď: ano.
