Un‘analisi tecnica dettagliatissima di due università britanniche mostra che WhatsApp è effettivamente molto sicura per le conversazioni tra due persone, ma rivela anche che le chat di gruppo non sono altrettanto ben protette contro le intrusioni e gli ascolti indesiderati, nonostante la crittografia “end to end” che WhatsApp mette sempre in evidenza. Un confronto con le altre app di messaggistica rivela pro e contro di ciascuna e spiega come evitare o almeno contenere l’insicurezza segnalata dai ricercatori.
