Rensenware (; stylized as rensenWare) is a ransomware that infects Windows computers. It was created as a joke by Kangjun Heo (; alias "0x00000FF") and first appeared in 2017. Rensenware is unusual as an example of ransomware in that it does not request the user pay the creator of the virus to decrypt their files, instead requiring the user to achieve a required number of points in the shoot 'em up video game Undefined Fantastic Object before any decryption can take place. The main window displays Minamitsu Murasa, a character from the game. Heo released a patch that neutralizes Rensenware aft

Bluetooth vulnerability, an attack vector

Cloudbleed was a Cloudflare buffer overflow disclosed by Project Zero on February 17, 2017. Cloudflare's code disclosed the contents of memory that contained the private information of other customers, such as HTTP cookies, authentication tokens, HTTP POST bodies, and other sensitive data. As a result, data from Cloudflare customers was leaked to all other Cloudflare customers that had access to server memory. This occurred, according to numbers provided by Cloudflare at the time, more than 18,000,000 times before the problem was corrected. Some of the leaked data was cached by search engines.
