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...
Collision Attack: Widely Used SHA-1 Hash Algorithm Needs to Die Immediately

Collision Attack: Widely Used SHA-1 Hash Algorithm Needs to Die Immediately

Oct 08, 2015
SHA-1 – one of the Internet's widely adopted cryptographic hash function – is Just about to Die. Yes, the cost and time required to break the SHA1 algorithm have fallen much faster than previously expected. According to a team of researchers, SHA-1 is so weak that it may be broken and compromised by hackers in the next three months. The SHA-1 algorithm was designed in 1995 by the National Security Agency (NSA) as a part of the Digital Signature Algorithm. Like other hash functions, SHA-1 converts any input message to a long string of numbers and letters that serve as a cryptographic fingerprint for that message. Like fingerprints, the resulting hashes are useful as long as they are unique. If two different message inputs generate the same hash (also known as a collision ), it can open doors for real-world hackers to break into the security of banking transactions, software downloads, or any website communication.

Product Walkthrough: How Satori Secures Sensitive Data From Production to AI

Jan 20, 2025Data Security / Data Monitoring
Every week seems to bring news of another data breach, and it's no surprise why: securing sensitive data has become harder than ever. And it's not just because companies are dealing with orders of magnitude more data. Data flows and user roles are constantly shifting, and data is stored across multiple technologies and cloud environments. Not to mention, compliance requirements are only getting stricter and more elaborate.  The problem is that while the data landscape has evolved rapidly, the usual strategies for securing that data are stuck in the past. Gone are the days when data lived in predictable places, with access controlled by a chosen few. Today, practically every department in the business needs to use customer data, and AI adoption means huge datasets, and a constant flux of permissions, use cases, and tools. Security teams are struggling to implement effective strategies for securing sensitive data, and a new crop of tools, called data security platforms, have appear...
