As far as I know, it's simply an IP/domain-based "blacklist"... likely caused by miscreants abusing certain IP/domains for nefarious purposes in the past... now MalwareBytes thinks anything attempting to connect to these IP/domains using certain ports is "Phishing" or "Exploits"
False positives like this are a real issue... as they make people unnecessarily concerned about legitimate software, but also because they get annoying and then people stop trusting the anti-virus/anti-malware software!
