The Koobface Gang Wishes the Industry "Happy Holidays"

Oops, they did it again - the Koobface gang, which is now officially self-describing itself as Ali Baba and the 40 Thieves LLC, has not only included a Koobface-themed -- notice the worm in the name -- background on Koobface-infected hosts, but it has also included a "Wish Koobface Happy Holidays" script -- last time I checked there were 10,000 people who clicked it -- followed by the most extensive message ever left by the gang, which is amusingly attempting to legitimize the activities of the gang.

In short, the message with clear elements of PSYOPS, attempts to position the Koobface worm as a software, where the new features are requested by users, and that by continuing its development, the authors are actually improving Facebook's security systems. For the record, the Koobface botnet itself is only the tip of the iceberg for the malicious activities the group itself is involved in. Consider going through the related Koobface research posts featured at the bottom of the post, in order to grasp the importance of how widespread and high-profile the activities of this group are. The exact message, screenshot of which is attached reads:

Our team, so often called "Koobface Gang", expresses high gratitude for the help in bug fixing, researches and documentation for our software to:

Kaspersky Lab for the name of Koobface and 25 millionth malicious program award;
Dancho Danchev (http://ddanchev.blogspot.com) who worked hard every day especially on our First Software & Architecture version, writing lots of e-mails to different hosting companies and structures to take down our Command-and-Control (C&C) servers, and of course analyzing software under VM Ware;
Trend Micro (http://trendmicro.com), especially personal thanks to Jonell Baltazar, Joey Costoya, and Ryan Flores who had released a very cool document (with three parts!) describing all our mistakes we've ever made;
Cisco for their 3rd place to our software in their annual "working groups awards";
Soren Siebert with his great article;
Hundreds of users who send us logs, crash reports, and wish-lists.

In fact, it was a really hard year. We've made many efforts to improve our software. Thanks to Facebook's security team - the guys made us move ahead. And we've moved. And will move. Improving their security system.

By the way, we did not have a cent using Twitter's traffic. But many security issues tell the world we did. They are wrong. As many people know, "virus" is something awful, which crashes computers, steals credential information as good as all passwords and credit cards. Our software did not ever steal credit card or online bank information, passwords or any other confidential data. And WILL NOT EVER. As for the crashes... We are really sorry. We work on it :) Wish you a good luck in new year and... Merry Christmas to you!

Always yours, "Koobface Gang".

For the record, in case you were living on the other side of the universe, and weren't interested in the raw details taking place within the underground ecosystem, in July, 2009, I was the only individual ever mentioned by the Koobface gang, which back then included the following message within the command and control infrastructure for 9 days:

"We express our high gratitude to Dancho Danchev (http://ddanchev.blogspot.com) for the help in bug fixing, researches and documentation for our software."

Next to the folks at TrendMicro, the DHS also featured the event in DHS Daily Open Source Infrastructure Report for 3 September 2009 at page 18:

"This individual is an independent security consultant who plays an active role in tracking and shutting down botnets and other illegal operations."

It got ever more personal when the Koobface gang redirected Facebook's entire IP space to my blog in October, 2009, resulting in thousands of Facebook visits every time their crawlers were visiting a Koobface-infected host. Thankfully, Facebook's Security Incident Response Team quickly took care of the issue.

In the spirit of Christmas, I'd also like to wish the Koobface gang happy holidays, and promise them that the cherry on the top of the research pie will see daylight anytime soon. First of all, I'd like to wish them happy holidays with Frank Sinatra - "I've got you under my skin". They'll get the point.

And now comes my Christmas present, systematic take-down, blacklisting, and domain suspension of Koobface scareware operations.

Sample detection rates by Koobface binaries - go.exe; fb.79.exe; fblanding.exe; v2captcha.exe; v2webserver.exe; pack_312s3.exe (the scareware).

Koobface-Friendly Riccom LTD - AS29550 - (Finally) Taken Offline

Last week, Josh Kirkwood, Network Engineer at Blue Square Data Group Services Limited, with whom I've been keeping in touch regarding the blackhat SEO activity courtesy of the Koobface gang, and actual Koobface botnet activity that's been taking place there for months, pinged me with an interesting email - "Riccom are now gone" (AS29550). He also pinged the folks at hpHosts in response to their posts once again emphasizing on the malicious activity taking place there.

Since I've been analyzing Riccom LTD activity in the context of "in-the-wild" blackhat SEO campaigns launched by the Koobface gang, followed by establishing direct Koobace botnet connections, as well as sharing data with Josh, Riccom LTD clearly deserves a brief retrospective of the malicious activity that took place there.

Malicious activity I've been analyzing since August, 2009:

August 06 - scareware parked at 91.212.107.5 analyzed in "Blackhat SEO Campaign Hijacks U.S Federal Form Keywords, Serves Scareware"
August 10 - more scareware introduced at 91.212.107.5 analyzed in "U.S Federal Forms Blackhat SEO Themed Scareware Campaign Expanding"
August 18 - scareware domains continue getting introduced at 91.212.107.5, analyzed in "Dissecting the Ongoing U.S Federal Forms Themed Blackhat SEO Campaign"
August 19 - Actual Koobface command and control server parked within BlueConnex's ASN, they take action against 85.234.141.92 - "Three hours after notification, Blue Square Data Group Services Limited ensures that "the customer has been disconnected permanently". It's a fact. All of Koobface worm's campaigns currently redirect to nowhere."
September 14 - the malvertising attack at the web site of the New York Times, not only used a redirector that was simultaneously pushed by Koobface-infected host hosted on an IP known to be managed by the gang's blackhat SEO team ,but also, the actual scareware domain used relied on Riccom LTD hosting again at 91.212.107.103
September 16 - 91.212.107.103 remains the most widely abused IP hosting scareware served by the Koobface botnet. Action is taken again the entire .info tld domain portfolio, the domains are suspended within a 48 hours period of time courtesy of AFILIAS.
November 11 - cat and mouse game between the company, me, and the Koobface gang is taking place, now that a connection between the Koobface gang and the Bahama botnet has been clearly established. New scareware domains are introduced at 91.212.107.103, as well as at the still active AS44042 ROOT eSolutions. The Koobface gang once again proves it "knows my name" by typosquatting domains and registering them with typosquatted variants of my name (pancho-2807 .com is registered to Pancho Panchev, pancho.panchev@gmail.com, followed by rdr20090924 .info registered to Vancho Vanchev, vanchovanchev@mail.ru). Upon notification 91.212.107.103 has been taken offline courtesy of Blue Square Data Group Services Limited.
November 17 - A week later the gang resumes operations at the same Riccom LTD IP - "Tuesday, November 17, 2009: Koobface is resuming scareware (Inst_312s2.exe) operations at 91.212.107.103 which was taken offline for a short period of time. ISP has been notified again".

Clearly, in terms of cybercrime, especially one that's monetizing an asset with high liquidity such as scareware, "better late than never" doesn't seem to sound very appropriate.

A Diverse Portfolio of Fake Security Software - Part Twenty Four

Good traditions are not meant to be broken, in particular the "Diverse Portfolio of Fake Security Software" series. And with scareware losses to customers already (conservatively) estimated at $150 million, combined with the overwhelming evidence of scareware becoming the monetization method of choice for the majority of cybercriminals gathered throughout the entire year - in 2010 we'll see the peak of a fully matured business model that's offering one of the highest payout rates within the underground marketplace.

How can this underground business model be undermined? By hitting the"beehive" rather than hitting the campaign of particular "bee", and by disrupting the monetization flow ultimately leaving the "beehive" with hundreds of thousands of "bees" actively infecting without the opportunity to collect the cash flaw, thereby putting them in a position where the "beehive" becomes unable to pay the commissions to the "bees" at the first place.

Moreover, raising awareness on the most efficient and profitable monetization tactic used by cybecriminals in the face of scareware (The Ultimate Guide to Scareware Protection), is crucial for filling in the gaps, since in its current form, scareware is driven exclusively by social engineering tactics and aggressive traffic hijacking campaigns.

What's to come in 2010 anyway? It's the culmination of an year and half research. Stay tuned folks!

The following scareware domains have been recently observed in active campaigns online:

Celebrity-Themed Scareware Campaign Abusing DocStoc

UPDATE: Docstoc has removed all the participating accounts in this campaign, and is applying additional filtering to undermine its effectiveness.

Last week's "Celebrity-Themed Scareware Campaign Abusing DocStoc and Scribd" is now exclusively targeting the popular Docstoc document-sharing service. Naturally, this very latest campaign once again offers overwhelming evidence on the inner workings of the cybercrime ecosystem, in this particular case, the connection between the Koobface gang and money mule recruitment campaigns.

So let's cut to the chase before we expose the entire campaign, and have all the involved profiles removed. One of the most popular bogus video site link embedded in these documents, wildyourvideo .com - 188.130.250.246 - gevtone@gmail.com, is using NS1.FUCKABUSE .BIZ - abusehostserver@gmail.com - as its nameserver. The same email was also used to registered some of the client-side exploit serving domains part of the Koobface drive-by download experiment, and is also known to have been used in registering money-mule recruitment domains.
