PfBlocker

Sorry, I've never configured a syslog server on pfsense.

You can install almost any freebsd8.1 package on pfsense, so I think it will not That hard to configure.

I just installed the package but it seems that i must add manually urls to get ip lists to deny.
I think it could be great to have the option of a drop down list with most known black list of spam, malware, etc… without having to put it manually, of course, at the end for example an option like "custom" where you can put custom urls.

The great option is to indentify the most stable and sopported lists and make the package able to interprete them automatically.

I think could be great to add individually lists from google, antivirus companies, antispam blacklists,
Some examples to start looking for most interesting sources of ip lists:

http://sites.google.com/site/blocklist/
http://www.phishtank.com/

http://www.getmantra.com/galley/malwares/index.html
and alienware, the authors of OSSIM hace another great service of ip reputation to do something similar to spamassasin with ip addresses:

You can add any ip based/cidr list to pfblocker but there is no plan to create dropdown list pointing to external links.

Anyway, thanks for you suggestion.

Hi all,

The country lists that we use on pfblocker will move to a paid service, take a look:

I combined the Bluetack Level 1 and the TBG Primary Threats lists. I converted them into CIDR and (I hope) trimmed out the overlapping ranges.
Neither Pastebin nor Pastie would take 6MB pastes so I sent the gz files to an uploader service.

IPs .0-.68 http://efjf7g.dl4free.com/en/
IPs .69-.193 http://6pvjo6.dl4free.com/en/
IPs .194-255 http://zsh382.dl4free.com/en/

Here's the CIDR count

The original Peerguardian formatted files from IBlocklist seem to require a lot of resources to convert.

Also, BlueTackL1 and TGP-PT have a lot of overlap so I felt converting+filtering them would help minimize resources.

Sorry - I'm not clever enough to automate this process or offer a live update service.

Since these are blind d/l's for you, prudence dictates you examine the contents before use.

:-(

So does that mean we will have to subscribe and then add the lists into pfblocker ourselves?

US Spammers:
IPs 0-68 http://pastebin.com/iKTpuy9n
IPs 69-179 http://pastebin.com/8Z6iSCSp
IPs 180-255 http://pastebin.com/PJLjUWeA

Other Spammers:
Worst: http://pastebin.com/aKnBhMLX
Corp Spamvertisers: http://pastebin.com/3Yd97rZ4
Non-US: http://pastebin.com/t9ej10BZ

Worst Spammers are the nitwits who were filling up my logs so I moved them into their own group.
They may not be targeting you and could be wrapped into other lists.

Corp Spam is stuff like Constant Contact, Linked-In, FTD, PsychzNetworks, ExactTarget….
They may not be blacklisted by DNSBLs but they're a pain in my butt.

Attn: marcelloc and Tommyboy180
I can't tell if my PMs get through to you because my browser doesn't properly redirect after posting.

The URLs I sent you before you have new filenames. They are:
US_SpamIPs_0-69.txt.gz
US_SpamIPs_70-179.txt.gz
US_SpamIPs_180-255.txt.gz
Non-US_Spam_IPs.txt.gz
CorporateSpam.txt.gz
Worst_Spammers.txt.gz

The rest of the URL is the same.

marcelloc, if you'd delete the old files you're hosting and post these instead I'd appreciate it.

Linuxtracker,
I did received Pm, I'll publish files this week.

Kilthro,
Updated lists will need a subscribe but the files we already have will still be there.

Until april I'll update lists again and of course try to implement countryip subscription on pfBlocker package.

That's what I thought. Thanks for the clarification.

Not good enough marcelloc. I want more things done and I want them done now.
. . . or not.

I guess busting your tail for little more than a thanks will have to be good enough for me.

Hi guys,

This seems to be the most appropriate place to ask this question, since it closest matches my need.

There have been a few recent reports re issues associated with ads on mobiles, as well putting load on batteries (hardly seems surprising), and I don't want to root my Android to block ads (if I can block ads for all nodes, all the better):

http://www.engadget.com/2012/03/19/android-study-privacy-security-risks-in-app-ads/
http://www.csc.ncsu.edu/faculty/jiang/pubs/WISEC12_ADRISK.pdf
http://www.pcworld.com/article/252204/free_android_apps_packed_with_ads_are_major_battery_drains.html

We have several such devices in-house, and I'd like to simply block the ads at the boundary.
I've seen posts (19756 & 12737) providing a hack by virtue of Squid (I'd like to avoid adding Squid for this limited function if possible, since it seems overkill), but I'd like to leverage something similar to the Android app AdFree, that simply does a hosts file amendment to void IP's/DNS's: http://www.mvps.org/winhelp2002/hosts.txt

I've tried manually adding this data to my firewall's hosts file, but it does not seem to take.

Any suggestions would be greatly appreciated.

Withdrawn for now.

I've done this by creating an alias of the mobile ad servers and adding a rule that blocked outbound traffic to them.

However, first I had to find the addresses for the mobile ad servers. I did that by packet capturing the IP of my mobile, while I opened the apps.

last edit:
This attempt to compile a list of malware IPs needs improvement. It functions but is picking up some legit domains.
I need to better vet my sources

I'm leaving it for reference.

wget "http://urlquery.net/index.php" -O data.txt
grep -Eo '([0-9]{1,3}\.){3}[0-9]{1,3}' data.txt | tail -n +3 > ips.txt

wget "http://minotauranalysis.com/malwarelist.aspx" -O data.txt
grep -Eo '([0-9]{1,3}\.){3}[0-9]{1,3}' data.txt | tail -n +3 >> ips.txt

wget "http://siteinspector.comodo.com/public/recent_detections/index" -O data.txt
grep -Eo '([0-9]{1,3}\.){3}[0-9]{1,3}' data.txt | tail -n +3 >> ips.txt

wget "http://siteinspector.comodo.com/public/recent_detections?page=2" -O data.txt
grep -Eo '([0-9]{1,3}\.){3}[0-9]{1,3}' data.txt | tail -n +3 >> ips.txt

cp malwaredomains.txt domains.txt
cat ips.txt domains.txt | sort | uniq > malwaredomains.txt

UrlQuery is offering up - https://gist.github.com/2191871 207.97.227.243 - as a Malicious domain.
That's the sort of problem I was running into w/ Malc0de.

Linuxtracker,

I think It's time to move shell scripts to php.
This way you can use arrays funcions like sort,unique as well php ip funcions and preg_match and preg_replace. ;)

marcelloc

Freakalad,

You can configure these host nanes on an pfsense alias or use dns forwarder to overide these ads hostname's ips.

Try alias first and put rejecting(better then deny for outgoing users) ads rule on top of lan rules.

If you could compile a txt via script with ads ips, then pfBlocker can help you on updating it Every x hours.

I'l have to look into previous posts re details, rather than trying to enter it manually through the GUI, one entry at a time.
I'll look into it end I get more time to attend to it.

I trust you're right. Unfortunately I haven't a clue about PHP.

This bit I've hacked together came out of a semester of Unix, from 20 years ago.

I'll take it under advisement though. Maybe I can start puzzling something out.
