DAO – Record Breaking Theft Worth 5OM$

Some 50 millions of dollars have been stolen from DAO token holders (including myself). The DAO is by the way, claimed to be closing [Tual].

Comparison of R&D Expenses in Different Countries

Researchers in Cryptography vs. Big Brother

For decades the dominant paradigm in crypto and security research would be: to claim that security vulnerabilities occur accidentally, ignoring major questions such as why there are so many of them and why the “bad scenarios” repeat so many times, concentrate security research on topics of secondary importance, or those which have no importance whatsoever and …

Stop Using Passwords, Now!

Edward Lucas wrote a nice piece on how businesses can dramatically improve their cyber-security. He says that: “Well-run organisations will stop using passwords and logins in 2016. Instead they will use identifiers that are harder to copy, fake, steal or guess […] Security questions will stop being […] “mother’s maiden name”. Instead they will ask …
