Shaw Cable Advisory

The entire Shawcable network seems to have been compromised with an inordinate number of exploited machines, open relays and zombies.

At this time, to prevent the spread of spam and malicious code, we are advising administrators to block ALL of Shawcable's space; white-listing where necessary.

An optimized CIDR listing is available here.

This list had to be compiled from our logs and several other sources. If you notice any errors or omissions, please report them promptly. Please note that the "spamtrap" and "dynamic" lists include only positive hits and do not incorporate the entirety of the Shawcable CIDR ranges referenced above. Using this list in conjunction with the "spamtrap" list creates some duplication which RBLDNSD handles very gracefully.
