Any reward for solving the puzzle is then split amongst the participants. Not all use of web-based

Eswatini’s official website is not the only government site compromised. Netcraft has detected
cryptojacking and other malicious infections on plenty of other sites on government second-level domains
including those of Mexico, Brazil, and Indonesia.
A script from the
driverfortnigtly[.]ga domain is currently referenced on the Guam Election Commission’s website.
The domain is now defunct and was previously used for
redirecting visitors to other sites.
Netcraft provides anti-cybercrime services to seven governments. To protect domestic internet users we
regularly scan and detect web servers that have been compromised and infected with malicious content.
