We are continuing to revalidate domains on the dns-bh list. These are domains which were identified as malicious anywhere between 90 and 360 days ago. but according to google safebrowsing, are still actively involved in badness.
Analysis of the hosting and registrars of these “immortal” or “Methuselah” malware domains should prove interesting.
