VB Editor Martijn Grooten recommends Jean-Philippe Aumasson's 'Serious Cryptography' as a very solid but practically focused introduction to cryptography.
This year, Alice and Bob will have been exchanging messages for 40 years. In terms of their contribution to cryptography, they have been almost as important as that other… https://virusbulletin.com/blog/2018/01/book-review-serious-cryptography/
Virus Bulletin was a proud sponsor of BSides London 2017 - Martijn Grooten reports on a great event.
This month, for the first time in its 28-year history, Virus Bulletin became the sponsor of another industry conference: BSides London. I have to admit to having been more than a… https://virusbulletin.com/blog/2017/06/review-bsides-london-2017/
Realistically speaking, if your software or system uses the SHA-1 hashing algorithm, it is unlikely that it will be exploited in the foreseeable future. But it is also extremely difficult to be certain that your system won't be the exception.
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.… https://virusbulletin.com/blog/2017/03/why-sha-1-collision-means-you-should-stop-using-algorithm/
Researchers from Google and CWI Amsterdam have created the first known collision of the SHA-1 hashing algorithm, making a very strong case to ditch it.
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… https://virusbulletin.com/blog/2017/02/sha-1-hashing-algorithm-has-been-shattered/
Crypto is hard, and malware authors often make mistakes. At VB2016, Check Point researchers Yaniv Balmas and Ben Herzog discussed the whys and hows of some of the crypto blunders made by malware authors. Today, we publish their paper and the recording of …
"More malware is using cryptography, and more malware is using better cryptography," said Check Point researcher Yaniv Balmas on stage during VB2016. While the increased use of… https://virusbulletin.com/blog/2017/01/vb2016-paper-great-crypto-failures/
At VB2016, two talks will discuss mistakes made by malware authors in cryptographic implementations. Ben Herzog and Yaniv Balmas will present a paper in which they look at a number of these mistakes, while Malwarebytes researcher hasherezade will present …
"Don't roll your own crypto", software developers are often told: cryptography is hard and thus it is always safer to use a well-tested public library rather than writing your own… https://virusbulletin.com/blog/2016/september/vb2016-preview-presentations-cryptography-mistakes-malware/
SHA-1 collisions may be found in the next few months, but that doesn't mean that fake SHA-1-based certificates will be created in the near future. Nevertheless, it is time for everyone, and those working in security in particular, to move away from outdat…
Earlier this month, I gave a talk entitled "How Broken Is Our Crypto Really?" at the RSA Conference in San Francisco. In the presentation, I looked at vulnerabilities found in… https://virusbulletin.com/blog/2016/03/how-broken-sha-1-really/
This Throwback Thursday we go back to 2004, when the entire crypto community was abuzz with the news that a group of Chinese researchers had demonstrated flaws in a whole set of hash functions - VB took a closer look to clarify the situation and draw less…
Just last week, VB Editor Martijn Grooten addressed an audience at the RSA Conference in San Francisco on the topic of cryptographic protocols that have supposedly been broken in… https://virusbulletin.com/blog/2016/03/throwback-thursday-hash-woes/
Next week, Virus Bulletin Editor Martijn Grooten will attend the RSA conference in San Francisco, where he will give a talk entitled "How Broken Is Our Crypto Really?" He will also speak at BSides San Francisco, where he will give a talk entitled "Ellipti…
Next week, almost everyone with a stake in or an opinion on IT security will be in San Francisco for the annual RSA Conference.
I will be there as well, and although Virus… https://virusbulletin.com/blog/2016/02/rsa-and-bsides-san-francisco/
