WhatsApp Vulnerability Allows Hacking into Group Chats


According to researchers, the WhatsApp mobile messaging facility has been found with vulnerability which can let hackers eavesdrop into secret group chats. The security flaw lets anybody having WhatsApp servers' access get inside a private cluster of callers alternatively make others join devoid of the chat admin's permission.


The problem raises concerns. For instance, outsiders could infiltrate a women's WhatsApp group in Westminster which conducts sensitive conversations like discussions on MPs' alleged sexual persecutions. This implies online crooks can make fresh individuals join the group chats on WhatsApp devoid of taking the group administrator's consent, thus allowing them gain admission into unwarranted information.


Hence, in spite of the end-to-end encryption facility in WhatsApp messaging there is possibility of infiltration and spying into group chats.


Researcher Paul Rosler from Ruhr University and co-author of one research paper that discussed the security flaw explained that the group's secrecy would be broken immediately when an uninvited member acquired access of every new message as well as read it. Trustedreviews.com posted this, January 11, 2018.

Moreover, when every WhatsApp group participant's mobile number becomes accessible to the outsider, the participants' secret keys also become accessible to that outsider. WhatsApp regards its users' security and privacy highly important.

From the research, it's evident that anybody getting hold over the application's servers can add fresh individuals into secret conversations of different groups devoid of requiring admin consent. However, according to Alex Stamos, Chief Security Officer of Wired Facebook, it isn't possible for a non-member infiltrating a WhatsApp group conversation.


As per the paper, which the cryptographers from Germany published, the weakness in protocol design described thereafter lets an attacker, who's monitoring a few of the chat missives that WhatsApp's server sends, make participation in the group else include other people into the group devoid of interaction whatsoever by those people.


Further, despite solely placing attention to WhatsApp, Signal and Threema, researchers observe their methodology as well as underlying model has a general objective while it's applicable to other instant messaging programs for secure groups, too. The researchers as well cataloged several countermeasure recommendations with respect to the 3 examined messaging applications.
