Zimsec website (www.zimsec.co.zw) SSL certificate expired, the website is no longer secure. The website will soon start getting hacked from MITM attacks.
MITM or Man in the Middle is a kind of attack where an attacker creates interference between two ends (server and browser). The attacker secretly alters the communication so that it can result in losses. Without an SSL certificate, all the communication traveling from the webserver to the client is accessible, which makes it easy for intruders to target such type of unsecured communication.
