New research into attacks against the SHA-1 cryptographic algorithm lessen the cost and time to arrive at a practical collision. When Bruce Schneier made his oft-cited and mathematically sound ...

Using computing power from a cluster of 200 PS3 game consoles and about $700 in test digital certificates, a group of hackers in the U.S. and Europe have found a way to target a known weakness in the ...

In 2009, while I was researching Surviving Cyberwar, I attended the COSAC security conference outside of Dublin for the first time. During an open session I posed this question to the attendees: “Can ...

I was reading the new Ars article about Microsoft's decision to retire SHA-1 due to its vulnerability to collision attacks. The article mentions the well-publicized Flame attack of 2012, a key ...

Uber-malware Flame is the most complex tool for cyber espionage discovered in the wild to-date, expert cryptographers have said, the first example of an MD5 collision attack being used in earnest.

In general, unless you're specifically tailoring input to produce collisions, collision risk of a (formerly, in case of md5 and by now also sha1) cryptographically secure hash function is not ...

A design flaw in the decades-old RADIUS authentication protocol allows attackers to take over network devices from a man-in-the-middle position by exploiting MD5 hash collisions. The “secure enough” ...

LAS VEGAS—Elie Bursztein, Google's lead anti-fraud researcher, began his talk here at Black Hat 2017 with an understatement: "It has been a long and interesting journey over the last few years." In ...
