hotlog.ru?
by Jeff Chan 08 Aug '05

08 Aug '05

hotlog.ru and some subdomains appeared in the SURBL data yesterday, but the site is also ranked about 25k on Alexa so it seems to be a fairly popular site. A couple readers of Russian took a look at the site and determined it's some kind of web log analysis tool vendor, but could not easily say if it had legitimate uses. Is anyone here familiar with them? In particular might they have legitimate uses? It's been around since 2000: domain: HOTLOG.RU type: CORPORATE nserver: ank.ank.ru. nserver: ns.wplus.net. nserver: ns1.wplus.net. state: REGISTERED, DELEGATED person: ANDREW N KUZMIN phone: +7 812 5963532 fax-no: +7 812 5963532 e-mail: ank(a)ank.ru registrar: RUCENTER-REG-RIPN created: 2000.11.29 paid-till: 2005.11.30 source: TC-RIPN Jeff C. -- Don't harm innocent bystanders.

If the SA folks don't have time to do a corpus check on SC2, then maybe we should go ahead and put SC2 into production. I'd still feel better with a large ham check from them before doing it though.

SURBL: sc2 vs sc?
by Jeff Chan 04 Aug '05

04 Aug '05

It's sounding like the sc2 list is catching 10-15% more spam than the sc list, based on some early reports of SA users. Is anyone else getting some results? Are there differences in ham hits? Has anyone been able to run them through their test corpora? How about xs.surbl.org? Jeff C. -- Don't harm innocent bystanders.

Steve, I'm not a procmail user and nearly all your expressions look good except a few. If you have any users into genealogy the next~of~kin pair may give you problems; I get mail like this from family members who are "into" that sort of thing. Also, my accountants will sometimes send me emails with urgent_response and/or urgent_reply in them. All the rest seem to match what I have seen in 419s only - a really good list overall. (BTW. Bayes is good at catching these too. How often does an American even see or hear the word "barrister"? Ouside of the Commonwealth or old Commonwealth countries, I doubt the work gets any use except on PBS; And who *really* wants to hear from a lawyer anyway:-)) Paul Shupak track(a)plectere.com

RFC: Adding SpamBouncer phishing data to ph.surbl.org
by Jeff Chan 02 Aug '05

02 Aug '05

Catherine Hampton of SpamBouncer (welcome to the SURBL Discuss list Catherine!) is kindly making available her carefully checked phishing domains and IPs for our inclusion in the SURBL phishing list. They're not currently added to ph.surbl.org, but the hooks are in place to make it live after some discussion here. Catherine's data come from antiphishing.org plus her own trapped phishes. All are hand checked about once a day. When I reviewed a recent snapshot of the data: http://www.spambouncer.org/dist/standalone/phishdata/current.txt I found that 124 of the 193 domains were already listed on various SURBLs. The other new 69 looked quite phishy and probably ok to list. For the IPs, we had 22 of the 74 listed, and I'll assume the others are probably zombies, etc. as Catherine suggested. Generally speaking there's little harm in listing IPs since most legitimate sites don't get referenced by IP, so there's good upside and little downside for listing them. Please take a look at the data for yourself and comment. Regarding expiring the data, Catherine told me: > I expire "Phish IP" listings every month. Phishers move around a > LOT, probably because most of the IPs are on compromised or trojaned > hosts and tend to get fixed within a couple of weeks. > > I don't expire Phish domains formally right now, although eventually > I plan to run them through regular "has this domain expired and not > been renewed" checks. Since I only list domains designed specifically > for phishing and used only by phishers as "Phish domains", they aren't > likely to be used for anything else. (Domains like paypalll.com > don't seem to have much legitimate use to me.) which sound like reasonable policies to me. Does anyone have comments on adding these to the PH list? Am I forgetting anything Catherine? :-) Jeff C. -- Don't harm innocent bystanders.

I agree, we definitely need SURBL black lists. They have helped tremendously against spam! I just feel that it would be chasing one's tail a bit to try to catch phishing in SURBL. People who do phishing are going to change their IP address (IP where the actual target/sucker is sent) frequently. They are also probably going to use random and ever changing computer IPs outside the US for obvious legal reasons. Maybe zombies even, who knows. Any domain names in a phishing email code are most likely going to be legit domain names such as, ebay.com, bankofamerica,com, southtrustbank.com etc.. These are the domains visible to the target/sucker. So it just seems to me that an antivirus program is better for detecting HTML code patter of these schemes rather than the IP address of the day/week that they would be sending from in South Korea, Russia or China, etc. There is a very simple ClamAV plugin that does this (see the SA Wiki). I am using it on my SA system and it does the job of sending it on to my next downstream systems marked as spam. I have more antivirus on downstream systems that will delete real viruses as well since I just use ClamAV for spam tagging for simplicity sake. (I don't want to put a ton of programs on the computer to call SA, such as Amavis-new, etc., so that is why I do this.) >And by the way: I REALLY appreciate your SURBL lists and hard >work even if I think other tools supplement and help make your >stuff even better. > >My security principles include (but are not limited to): > > 1) Stop as much as possible at the outer perimeter > (earlier the better) > > 2) Defense in depth > >For us, the virus scanning happens before the Spam tests; >early is good. > >-- >Herb Martin

Sure, and any additional pattern matching is probably useful for detecting phishes, but every phish I've seen has tried to direct someone to a fake web site. Web sites mentioned in spams, including phishing spams, are *precisely* what SURBLs are designed to detect. SURBLs are not designed to detect viruses at all, just web sites. Phishes don't usually have viruses, but they do have web sites.
