"Attacking all 500 million hashes at once, will incur a 500 million-fold slowdown against an already slow algorithm. Not a fun time, even for nation states. Super weak (like top50k) passwords will slowly but steadily fall, but any with even a hint of complexity are pretty safe."

Redwood City, California / Amsterdam, The Netherlands, July 7, 2016 – Avast Software, an industry-leading maker of the most trusted security software in the world, and AVG Technologies N.V., (NYSE: AVG), a developer of business, mobile and PC device security software applications, today announced that they have entered into a purchase agreement in which Avast will offer to purchase all of the outstanding ordinary shares of AVG for $25.00 per share in cash, for a total consideration of approximately $1.3B.

WhatsApp’s end-to-end encryption relies on the generation of unique security keys, using the acclaimed Signal protocol, developed by Open Whisper Systems, that are traded and verified between users to guarantee communications are secure and cannot be intercepted by a middleman.

However, WhatsApp has the ability to force the generation of new encryption keys for offline users, unbeknown to the sender and recipient of the messages, and to make the sender re-encrypt messages with new keys and send them again for any messages that have not been marked as delivered.

The recipient is not made aware of this change in encryption, while the sender is only notified if they have opted-in to encryption warnings in settings, and only after the messages have been re-sent. This re-encryption and rebroadcasting effectively allows WhatsApp to intercept and read users’ messages.

The security loophole was discovered by Tobias Boelter, a cryptography and security researcher at the University of California, Berkeley. He told the Guardian: “If WhatsApp is asked by a government agency to disclose its messaging records, it can effectively grant access due to the change in keys.”

Open Whisper Systems au sarit de cur in sus cam degeaba pentru ca nu e o problema in protocolul Signal
