Bots Tampering with TLS to Avoid Detection

Researchers at Akamai observed attackers using a novel approach for evading detection. This new technique - which we call Cipher Stunting - has become a growing threat, with its roots tracing back to early-2018. By using advanced methods, attackers are...

Cryptanalysis of SIMON-32/64

A weird paper was posted on the Cryptology ePrint Archive working link is via the Wayback Machine, claiming an attack against the NSA-designed cipher SIMON. You can read some commentary about it here. Basically, the authors claimed an attack so devastating that they would only publish a...

qpid-proton: TLS Man in the Middle Vulnerability

A cryptographic weakness was discovered in qpid-proton's use of TLS. If the qpid-proton client was used without client certificates, it would accept an anonymous cipher offered by the server. A man-in-the-middle attacker could use this to silently intercept traffic that should have been encrypted...

Insecure Cipher Suites

excon uses insecure SSL cipher suites. The usage of insecure 3DES ciphers enables a remote attacker to carry out man-in-the-middle attacks...

Zombie POODLE and GOLDENDOODLE Vulnerabilities

Recently new vulnerabilities like Zombie POODLE, GOLDENDOODLE, 0-Length OpenSSL and Sleeping POODLE were published for websites that use CBC Cipher Block Chaining block cipher modes. These vulnerabilities are applicable only if the server uses TLS 1.2 or TLS 1.1 or TLS 1.0 with CBC cipher modes...

CVE-2019-1543

ChaCha20-Poly1305 is an AEAD cipher, and requires a unique nonce input for every encryption operation. RFC 7539 specifies that the nonce value IV should be 96 bits 12 bytes. OpenSSL allows a variable nonce length and front pads the nonce with 0 bytes if it is less than 12 bytes. However it also...
