What would help is to be able to block an IP once it's been hit. Thing is
I cannot for the life of me figure out a way to do it. Here's the first 25
that hit me today:
[12.166.16.7]
[12.166.16.7]
[12.166.16.7]
[12.166.16.7]
[12.166.16.7]
[12.166.16.7]
[12.166.16.7]
[12.166.16.7]
[12.17.134.9]
[128.143.2.219]
[128.143.2.219]
[128.146.216.43]
[128.146.216.45]
[129.82.100.130]
[129.82.100.130]
[130.244.199.129]
[130.244.199.132]
[132.64.1.17]
[142.165.19.3]
[142.165.19.5]
[142.169.1.100]
[144.135.24.153]
[144.135.24.153]
Notice the duplicates. Now if I could enter a blacklist entry into
shorewall after the first hit...
[EMAIL PROTECTED]:/var/log/exim4# grep -i malware mainlog | awk '{print $5}' |
sort
| wc -l
743
[EMAIL PROTECTED]:/var/log/exim4# grep -i malware mainlog | awk '{print $5}' |
sort
| uniq | wc -l
336
I'd drop the load from 743 down to 336. Assuming all of those are Swen or
some variant then it would be a savings of about 4Mb so far today.
Of course that's what's gotten past the IPs I've already blacklisted.
