Feed Name: The Spamhaus Project
Spamhaus reports that Resilans AB leased multiple IP netblocks to a snowshoe spam operation from August 2013 through February 2014, culminating in 47 /24 ranges (17,664 IPv4 addresses) and over 8,700 spammer PTR records. After repeated notifications failed to stop the abuse, Spamhaus applied large SBL listings on 27 February 2014; Resilans responded and the listings were removed the same day. The report documents the scale of the spam campaign, the indicators (IP ranges and PTRs), and Spamhaus's mitigation actions and expectations for future cooperation.
