Google Achieves First-Ever Successful SHA-1 Collision Attack

Google Achieves First-Ever Successful SHA-1 Collision Attack

Feb 23, 2017
SHA-1, Secure Hash Algorithm 1, a very popular cryptographic hashing function designed in 1995 by the NSA, is officially dead after a team of researchers from Google and the CWI Institute in Amsterdam announced today submitted the first ever successful SHA-1 collision attack. SHA-1 was designed in 1995 by the National Security Agency (NSA) as a part of the Digital Signature Algorithm. Like other hashes, SHA-1 also converts any input message to a long string of numbers and letters that serve as a cryptographic fingerprint for that particular message. Collision attacks appear when the same hash value (fingerprint) is produced for two different messages, which then can be exploited to forge digital signatures, allowing attackers to break communications encoded with SHA-1. The explanation is technologically tricky, but you can think of it as attackers who surgically alters their fingerprints in order to match yours, and then uses that to unlock your smartphone. The researchers h

The National Institute of Standards and Technology (NIST) had published a document on Jan 2011 that the SHA-1 algorithm will be risky and should be disallowed after year 2013, but it was recently noticed by Netcraft experts that NIST.gov website itself were using 2014 dated SSL certificate with SHA-1 hashes. " From January 1, 2011 through December 31, 2013, the use of SHA-1 is deprecated for digital signature generation. The user must accept risk when SHA-1 is used, particularly when approaching the December 31, 2013 upper limit. SHA-1 shall not be used for digital signature generation after December 31, 2013. " NIST in the document. Digital signatures facilitate the safe exchange of electronic documents by providing a way to test both the authenticity and the integrity of information exchanged digitally. Authenticity means when you sign data with a digital signature, someone else can verify the signature, and can confirm that the data originated from you and was not

How Nation-State Actors Target Your Business: New Research Exposes Major SaaS Vulnerabilities

Feb 15, 2024SaaS Security / Risk Management
With many of the highly publicized 2023 cyber attacks revolving around one or more SaaS applications, SaaS has become a cause for genuine concern in many boardroom discussions. More so than ever, considering that GenAI applications are, in fact, SaaS applications. Wing Security (Wing), a SaaS security company, conducted an analysis of 493 SaaS-using companies in Q4 of 2023.  Their study reveals  how companies use SaaS today, and the wide variety of threats that result from that usage. This unique analysis provides rare and important insights into the breadth and depth of SaaS-related risks, but also provides practical tips to mitigate them and ensure SaaS can be widely used without compromising security posture.  The TL;DR Version Of SaaS Security 2023 brought some now infamous examples of malicious players leveraging or directly targeting SaaS, including the North Korean group UNC4899, 0ktapus ransomware group, and Russian Midnight Blizzard APT, which targeted well-known organizat
