Diffie-Hellman | Breaking Cybersecurity News | The Hacker News

The OpenSSL Foundation has released the promised patch for a high severity vulnerability in its cryptographic code library that let attackers obtain the key to decrypt HTTPS-based communications and other Transport layer security (TLS) channels. OpenSSL is an open-source library that is the most widely used in applications for secure data transfers. Most websites use it to enable Secure Sockets Layer (SSL) or Transport Layer Security (TLS) encryption. However, after serious security vulnerabilities were discovered in OpenSSL over the last few years, the crypto library has been under much investigation by security researchers. The latest bugs affect OpenSSL versions 1.0.1 and 1.0.2, which has been patched in new releases of OpenSSL, versions 1.0.1r and 1.0.2f . The team has patched two separate vulnerabilities in OpenSSL. The " high severity " bug, identified as CVE-2016-0701 , addresses issues in the implementations of the Diffie-Hellman key exchang...

Yes, it seems like the mystery has been solved. We are aware of the United States National Security Agency (NSA) powers to break almost unbreakable encryption used on the Internet and intercept nearly Trillions of Internet connections – thanks to the revelations made by whistleblower Edward Snowden in 2013. However, what we are not aware of is exactly how did the NSA apparently intercept VPN connections, and decrypt SSH and HTTPS, allowing the agency to read hundreds of Millions of personal, private emails from persons around the globe.

Now, computer scientists Alex Halderman and Nadia Heninger have presented a paper at the ACM Conference on Computer and Communications Security that advances the most plausible theory as to how the NSA broke some of the most widespread encryption used on the Internet. According to the paper, the NSA has exploited common implementations of the Diffie-Hellman key exchange algorithm – a co...

You can tell the story of the current state of stolen credential-based attacks in three numbers: Stolen credentials were the #1 attacker action in 2023/24, and the breach vector for 80% of web app attacks . (Source: Verizon). Cybersecurity budgets grew again in 2024, with organizations now spending almost $1,100 per user (Source: Forrester).  Stolen credentials on criminal forums cost as little as $10 (Source: Verizon). Something doesn't add up. So, what's going on? In this article, we'll cover: What's contributing to the huge rise in account compromises linked to stolen creds and why existing approaches aren't working.  The world of murky intelligence on stolen credentials, and how to cut through the noise to find the true positives. Recommendations for security teams to stop attackers from using stolen creds to achieve account takeover. Stolen credential-based attacks are on the rise There's clear evidence that identity attacks are now the #1 cyber threat f...
