Jaromir Miko Well, this didn't go very well. WhatsApp is quite popular and we can basically call it a decent replacement for iMessage on devices that don't support it. Recently, however, it has faced criticism regarding its security: already at the beginning of this year, it was reported that hackers close to the Saudi prince used WhatsApp to break into the iPhone of the richest man in the world.

German magazine Deutsche Welle journalist Jordan Wildon revealed on Friday that Google indexes invitations to your group conversations. The truth of the statement was confirmed by Jane Wong, a programmer who specializes in reverse engineering applications. Just by typing the words "chat.whatsapp.com" Google found 470 links for random people to join your conversations.

Interestingly, many "private" conversations focus on sharing pornographic content or other topics that we will not discuss here. We managed to find, for example, a group chat of a certain Colombian party or a tuning group, and the Motherboard server managed to find a group chat of members of UN-accredited NGOs. When the editor joined them, he also saw their phone numbers.
A Google spokesperson said that search engines index links that are shared on the open Internet, such as in Facebook groups. He also adds that the company offers tools to disable certain kinds of links from being indexed. A WhatsApp spokesperson said that group administrators can share links to conversations both in private chats and publicly on the Internet, but there may be indexation of search links. The company recommends that users only share links with those who should have access to the conversations.
Total nonsense, WhatsApp has no problem. When someone posts a link to a WhatsApp group on the internet, Google indexes it because it's their job. Everything works as it should. If someone doesn't want Google to index their WhatsApp chat, they shouldn't publicly display a link to that chat.
What is "reverse programming the application"? :D
I'd say they mean programmers who make a living finding weaknesses/bugs/imperfections in applications. Then they report the bug and the creator pays them for it.
