We have computed the very first chosen-prefix collision for SHA-1. To put it in another way: all attacks that are practical on MD5 are now also practical on SHA-1.
We have reduced the cost of a collision attack from 2^64.7 to 2^61.2, and the cost of a chosen-prefix collision attack from 2^67.1 to 2^63.4.
Demo: The legacy branch of GnuPG (version 1.4) is vulnerable. We have created two PGP keys with different UserIDs and colliding certificates.

Do not use the Android clipboard for passwords, logins, card numbers, or any kind of sensitive data.
With Android, the clipboard can be read anytime by any app. No permission needed. And the app can then send your data to someone else. If you want to see this, fetch the Clip Stack app from Fdroid, it shows you the clipboard history, and lets you access previous content. #android
