Dear Sentinels
Wow, another bumper issue this week. First, we have news for around the web, the we look at the ever-growing cybercriminal threat, and finally, and this is not overstating it, we look at the biggest hack that has been stopped dead in its tracks. This hack is none other than WhatsApp.
WhatsApp's end-to-end encryption kept messages safe, but a major flaw in its contact-discovery system allowed researchers to map 3.5 billion active accounts worldwide. That's billion with a B! The issue, caused by a lack of rate-limiting, allows them to rapidly check phone numbers and expose extensive metadata such as phone numbers, public keys, timestamps, and even device types. Although message content was never at risk, the study showed how metadata alone can reveal detailed user profiles and global usage patterns, even uncovering millions of WhatsApp users in countries where the app is officially banned!
