Flash version distributed in China after EOL is installing adware
Found on ZD Net on Sunday, 07 March 2021
Currently, this Chinese version of the old Flash Player app is available only via flash.cn, a website managed by a company named Zhong Cheng Network, the only entity authorized by Adobe to distribute Flash inside China.
During subsequent analysis, researchers found that the app was indeed installing a valid version of Flash but also downloading and running additional payloads.
Flash has been a security problem. Now after it's official death still is. Nothing seems to have changed.
