Google is indexing invite links to WhatsApp group chats whose administrators may want to be private. This means with a simple search, random people can discover and join a wide range of WhatsApp group chats. From a report:

“Your WhatsApp groups may not be as secure as you think they are,” Jordan Wildon, a multimedia journalist for German outlet Deutsche Welle, tweeted on Friday. Using particular Google searches, people can discover links to the chats, Wildon explained. App reverse-engineer Jane Wong added in a tweet that Google has around 470,000 results for a simple search of “chat.whatsapp.com,” part of the URL that makes up invites to WhatsApp groups.
Motherboard used a number of specific Google searches to find invite links to WhatsApp groups. Some of the groups appear to not be overly sensitive or for a particular audience. Many of the links on Google lead to groups for sharing porn. But others appear to be catered to specific groups. Motherboard entered one WhatsApp group chat that described itself as being for NGOs accredited by the United Nations. After joining, Motherboard was able to see a list of all 48 participants and their phone numbers.
