Why the SHA-1 collision means you should stop using the algorithm
Unexpected though it may have been, the SHA-1 collision found by researchers at CWI Amsterdam and Google earlier this year is one of the biggest security stories of 2017 thus far. Now, stories about breaking cryptographic protocols tend to attract a disproportionate amount of media attention compared to the likelihood of them ever being exploited…

The SHA-1 hashing algorithm has been ‘shattered’
Researchers from Google and CWI Amsterdam have created the first publicly known SHA-1 collision. SHA-1 is a hashing algorithm: it turns data of arbitrary size (such as a string of text, or a file) into a fixed-length string, with a number of cryptographic properties . Hash functions are ubiquitous in IT in general and security in…

Paper: Optimizing ssDeep for use at scale
Brian Wallace presents tool to optimize ssDeep comparisons. Malware rarely comes as a single file, and to avoid having to analyse each sample in a set individually, a fuzzy hashing algorithm tool like ssDeep can tell a researcher whether two files are very similar — or not similar at all. When working with a large…
