So-called malicious domains curated from sources that only update occassionaly or already died. I therefore regard these maldoamins 'immortal'.
The domains' availability was checked by PyFunceble Project.
DNSBL - community project discontinued by RiskAnalytics
Baddboyz Hosts
Hexxium - community project still alive though updates are not frequent
MD-ID-Fork - maintained by bongochong on GitHub
hphosts (EXP,HJK,MMT,PUP) - acquired by Malwarebytes and intergrated into now proprietary browser guard extension. The domains classified into EMD are not included as the false positives are just too horrific. See: https://isc.sans.edu/diary/Domain+Whitelisting+With+Alexa+and+Umbrella+Lists/22270
malware domain list
rlwpx.free.fr.hrsk - last updated in March 2022
hostsfile.org (add.Risk) -last updated in 2018
Please note besides those still receiving updates frequently, hosts/domain blacklists that combine ads, tracking, spam and others with malicious domains are excluded. One example is mvps hosts. And I am not responsible for false positives included in original sources. The repo mostly serves as a monument to salute community efforts to combat maldomains in the old good days. They just gone away and I missed them.
