Whatsapp ak Signal krypte msg yo end to end. Sa vle di, app la jenere 2 kle: youn prive ki pa janm kite telefon (si nou kwè Meta) ak youn piblik ki ale jwenn kontak ou yo. Kontak yo use kle piblik la pu krypte msg y ap voye ba ou. Ou menm use kle prive a pu li yo(cryptographie)

Men si telefòn nan pirate, tankou ak lojisyèl Pegasus ki trè popilè, atakan an vin gen aksè dirèk ak telefòn nan. Sa vle di li gen aksè a msg yo menm anvan yo krypte yo. NSO Group vann lojisyèl sa a bay gouvènman, ofisyèlman nan kad lit kont teworis ak krim.

Pa sèl Pegasus ki egziste — gen lòt tankou Predator ki fè menm bagay. Pi gwo avantaj yo: viktim nan pa bezwen fè anyen pou enfekte, sèl nimewo telefòn li ka sifi ("zero-click"). Menm nimewo Pavel Durov, fondatè Telegram, te parèt sou yon lis sib potansyèl Pegasus depi 2018.
