SSL 2.0 Turns 30 This Sunday
SSL was created in February 1995. However, back in 2005, only a year later, SSL 3.0 was released, and as of 2011, SSL 2.0 was deprecated, and support was removed from many crypto libraries. However, over 400k hosts are still exposed via SSL 2.0.

Scammers Exploiting Deepseek Hype
