>CVE-2016-2183, CVE-2016-6329
>[...] short block size makes a block cipher vulnerable to birthday attacks, even if there are no cryptographic attacks against the block cipher itself. We observe that such attacks have now become practical for the common usage of 64-bit block ciphers
>We show that a network attacker who can monitor a long-lived Triple-DES HTTPS connection between a web browser and a website can recover secure HTTP cookies
