💬WhatsApp Not Well Encrypted🔐

Software researcher👓 Jonathan Zdziarski has found that 💬WhatsApp retains & stores a forensic trace🔎 of the chat logs💬 even after chats get deleted❌. The data can be recoverable through many remote backup systems. Zdziarski found this out after examining disk images📀 from the most recent version of 💬WhatsApp & blames the issue to the SQLite library used in the app. Although in most cases the app itself deletes the data🔢, but because it isn’t overwritten it can be recovered. 💬WhatsApp uses the much applauded Signal protocol but only protects the data in transit which prevents carriers from spying👀 on conversations. In the iCloud, they are backed up without hard encryption so 👮🏼police can easily obtain clear records of conversations💬 through a court order even after it is deleted in the app. Zdziarski wrote💬, “The core issue here is that ephemeral communication is not ephemeral on disk… iMessage leaves a lot [of forensic traces].”
