刚看了下,已经不在这个黑名单里了,如下:
IP Address 211.160.170.245 is not currently listed in the CBL.
It was previously listed, but was removed at 2009-03-02 10:28 GMT
ATTENTION: At the time of detection, this IP was infected with, or NATting for a computer infected with a high volume spam sending trojan - it is participating or facilitating a botnet sending spam or spreading virus/spam trojans.
ATTENTION: if you simply repeatedly remove this IP address from the CBL without correcting the problem, the CBL WILL eventually stop letting you delist it and you will have to contact us directly.
This is the Waledac spamBOT
You MUST patch your system and then fix/remove the trojan. Do this before delisting, or you're most likely to be listed again almost immediately.
If this IP is a NAT firewall/gateway, you MUST configure the NAT to prevent outbound port 25 connections to the Internet except from your real mail servers. Please see our recommendations on NAT firewalls
If you are running a Barracuda anti-spam appliance, turn off the "bounce spam" feature before delisting. Barracuda appliances with the "bounce spam or virus" feature turned on are showering innocent third parties with bounces of email that they didn't send. This is called "backscatter", and can get you listed in quite a number of DNSBLs (including SpamCop). The CBL doesn't deliberately list for backscatter, but in the case of Barracuda's "bounced spam or viruses", sometimes the CBL is unable to distinguish between a BOT and a Barracuda sending it. This seems most common with Warezov detections.
The Microsoft MSRT (Malicious Software Removal Tool) stands a good chance of being able to find/remove the malicious software. If you can find which machine the malware is on. |
