WhatsApp recently shifted to end-to-end encryption (E2E) for its users for better security, but that might not actually be a great move. The problem with encryption is that it also blocks data protectors from noticing malicious activity on their networks.
Simeon Coney, chief strategy officer for AdaptiveMobile said, “WhatsApp’s encryption policy is a win for privacy advocates, but it will not stop the growth of spam on the platform and could make the problem worse. WhatsApp has always had limited spam control in place and encryption will make detecting spam and malicious links with malware that much more difficult.”
In the past few years, mobile carriers have made it difficult for spammers to send junk messages, but now they’re moving from SMS and MMS to WhatsApp. The transition is cheaper and easier. Spammers simply have to upload large number ranges to test if the number has a WhatsApp account and send them bulk messages.
