The news about LastPass hack broke recently. If the user had strong password, the password is not brute-forcable. However dictionary passwords along with passwords that are guessable with mutation and Markov chains can be broken up to length of 12 characters on one GPU even though LastPass’s key derivation function (KDF) using 100000 iterations. This means that if the attacker can crack user’s simple password, the attacker can download the encrypted blob containing passwords from LastPass and use the cracked password to decrypt them. The weakest link here is the password strength.

How we let a router get “cracked”
In the previous two blog posts about project Turris, we described how a telnet “minipot” helped us to uncover a possible botnet consisting mainly of home routers from ASUS (1, 2). In this article, we will describe one possible way how these devices might have been compromised.
More about the honeypot for Telnet and botnets
Three weeks ago we published preliminary results of data analysis of the honeypot for the Telnet protocol, which we have launched in test mode. Today we will look at the situation change after we installed the tool on all the Turris routers.
