The Worst Hosting Networks (for Spam)
By MailChannels | 2 minute read
Spammers have long used ISP networks to send spam, taking ownership of PCs and mobile devices and using them to send spam. But in recent years, defenses against this type of spamming have improved remarkably, making this type of spamming much less effective and profitable.
Not to be deterred, spammers have increased their focus on hosting providers, who offer powerful virtual private servers (VPS’es) not to mention compromise-able hosting accounts on large shared hosting machines. VPS boxes are easily obtained using stolen credit cards, and shared hosting accounts are easily compromised by guessing the password or via phishing attacks and other client compromises.
So, which hosting networks are the world’s greatest sources of spam? Here are the latest figures as determined by our research using publicly available data from the Composite Blocking List (CBL):
