Americans want security, don’t know how to get it

A study released today by the National Cyber Security Alliance (NCSA) and the Anti-Phishing Working Group (APWG) indicates that most Americans are genuinely concerned about online safety and security. Furthermore, according to the study, they recognize their responsibility to contribute to the Internet's overall security and are willing to take steps in that direction.

The biggest obstacle, perhaps unsurprisingly, is the lack of clear, concise instructions on what users should do to protect themselves. This is an area in which we, as an industry, have to improve. When you combine the complexity and diversity of available technologies with a lack of consistency around messaging, terminology, and visual symbols, it's no wonder that consumers are feeling confused.

The upcoming National Cybersecurity Awareness Campaign, which the NCSA and APWG are spearheading, should be a step in the right direction. It promises a unified messaging campaign to increase awareness nationwide, and perhaps even internationally. Of course, if this survey is any indication, this will be a challenge, as the issue isn't so much awareness of the problem, but rather awareness of the solution.

Over the coming months, StopBadware will be working with industry partners to help them do their part to protect consumers from badware. Part of this, undoubtedly, will be consumer education. Just as we (and, by extension, our partners like Google and Firefox) now offer webmasters specific tips on finding, removing, and preventing badware on their websites, we need to work together to present clear guidance for users on how to protect their computers, their handheld devices, and their online information.

Hijacked subdomains still serving malware

Last month the Unmask Parasites blog wrote about attacks using hijacked sudomains of legitimate websites to serve badware.  At the time of that articles publication the attacks had been going on for a month already.  We are still seeing a lot of infected websites pointing back to solk.seamscreative.info (on port 8080) and other sites like it.

The standard attack used in Driveby Downloads required the injection of iframes into normally benign sites however the landing or intermediary sites those iframes pointed to weren't normally registered to benign users.  This represents an interesting evolution of tactics by creating another layer of innocent victim into the network of infections.  The attack has been fairly successful if in the last two months the infected subdomains haven't been taken down yet.  

Considering our own methods of alerting the public to infections it is easy to see why.  The subdomains aren't something the owners will be on the look out for and the DNS registrar likely has no idea that attacks are occurring on their customer base.  According to the blog post at Unmask Parasites the most affected DNS registrar seems to be GoDaddy.  I don't know if this means there is some flaw in their DNS management panel or if legit customers have had their credentials stolen.  Either way this trend warrants more investigation.

UPDATE 7/28: The GoDaddy abuse team has been notified.

NSFOCUS, our newest data provider

We are pleased to welcome Chinese security firm NSFOCUS as a new data provider! NSFOCUS joins Google and Sunbelt Software in feeding our Badware Website Clearinghouse with updated information about URLs they have discovered to be bad. Like all of our data providers, NSFOCUS will participate in our independent review process.

We are particularly excited to work with NSFOCUS because their team's extensive knowledge will give us insight into the often opaque world of Chinese networks and hosting providers.

NSFOCUS's press release about the data provider arrangement can be found here.

Establishing expectations for AV vendors

At StopBadware, we're currently revising our guidelines for badware applications. The goal of these guidelines is to distinguish between applications that are badware (defined as "software that fundamentally disregards a user's choice about how his or her computer or network connection is used") and those that aren't. One major reason for distinguishing badware from non-badware applications is to help people make informed choices before installing software that may compromise their privacy or security.

It is in this context that we ask a question that has been troubling us: if a "legitimate" anti-virus or security product has to send data about your computer use (e.g., your web search or browsing history) back to the vendor's servers to protect you as promised, how clearly should that data usage be disclosed?

Historically, we have thought of surreptitious collection of this type of data as a badware behavior. But what if the data isn't really being collected or used in any nefarious way, and the transmission of the data is necessary to make the product work as intended?

Consider a product like McAfee SiteAdvisor, a free browser plug-in that informs you of the safety of websites as you visit them or while browsing through search results. SiteAdvisor has to query a McAfee server with the URL (or the hash of the URL) of every site you visit or find during a search.  This means that, if McAfee wanted to (or if a rogue employee gained access), a profile of your browsing history could be compiled and tied back to your IP address. Yet this is never disclosed in any visible way prior to or during installation. In fact, it's not even in the Privacy Policy. (It could be considered covered by a vague provision in the EULA about the collection of personal information from your computer necessary to the function of McAfee's security products.)

This is not unique to SiteAdvisor. Many AV products now query a centralized database about URLs and/or executables to ensure users are protected. In our experience, most of these products fail to disclose this potential threat to a user's privacy in any meaningful way.

So, back to the question. Is this a badware behavior, one that in this case is being perpetuated by several well-respected software companies? Or is it reasonable to expect that users either know or wouldn't care that their security comes at the price of a company having access to some private data? Is it dependent on the trustworthiness of the vendor or the stated use of the data once it's been received? What should we expect as a minimum bar from AV vendors whose products behave in this way?

Please let us know your thoughts in the comments!

What We Learned at ThePlanet (AS21844)

After months of looking into the infections of AS21844 (ThePlanet) we've decided to wrap up our investigations for now.  We have learned quite a bit from our communications with customers at ThePlanet.  While no one from ThePlanet has spoken with us officially we have learned that they possess a direct feed of infected URLs from Google.  This means that large customers of ThePlanet, such as HostGator, should have the ability to learn of infections directly from their provider.  Also partners such as Skenzo should be able to use the same list to purge previously infected, and now abandoned, domains from their monetization framework.  

For those of you that look at our Top 50 Infected Networks you'll notice that ThePlanet is still at the top.  There really should be an asterisk up there since some of those infections shouldn't be counted.  In particular the Skenzo related infections aren't actually a threat but are still listed due to a policy decision by the Safe Browsing team (which you can read about in a previous blog post).  The best solution for now is to get this list to Skenzo so they can remove it from their framework.  I am preparing this list for Skenzo right now but eventually, I hope, ThePlanet will provide it for them.  To add some transparency to our research I'll paste the top infected org names as reported by ThePlanet's RWhois server:

 

WebsiteWelcome 7909
Skenzo FZE 2838
Unidentified 683
Site5 LLC 430
Bahram Boutorabi 192
SiteGround.com Inc. 171
webserver-a-rackshack.directi.com 166
Mochanin Corp 136
maktoob.com 119
server sea 115
Payam Torkian 115
Our Internet_ Inc 112

 

Don't forget that some of the 7,909 infections listed as HostGator (WebsiteWelcome is the org name used by HostGator) are duplicates.  Our hosting providers tend to include multiple pages (and/or directories) per website host so these numbers require additional explanation.  If one were to sort the infections by unique domains alone the count would be noticeably less.  Applying some command line fu to one of the data files shows us the repetition is not nearly as high as it used to be.   Only four domains are repeated more than 10 times.

 

count domain
10 vadakarapally.org
12 attorney2traffic.org
16 e-sense.tv
17 niftysensex.com    


HostGator has roughly 7,563 unique infected domains according to our last count and ThePlanet has 20,298 unique infected domains with their true number likely around 17,000 (adjusting for Skenzo).  Where does that put ThePlanet in the context of our top 50 infected networks?  Exactly where they are now actually. The next closest network is GoDaddy's AS26496 with 11,576 infections.

AV vendors say most badware sites are compromised

A recent report from Symantec reinforces the idea that most web-based malware is distributed via compromised, legitimate sites:

In 2010 so far, using the same approach, the proportion of malicious domains that are legitimate [i.e., set up for reasons other than distributing malware] has increased dramatically compared to last year – it’s now about 90%.

On a related note, Avast reports that, despite popular belief, adult sites are not carrying the load of malicious content:

…the statistics are clear – for every infected adult domain we identify there are 99 others with perfectly legitimate content that are also infected.

Everyday Internet users who are hearing this for the first time should take this as a wake-up call. Protect your computer. Protect your website. And recognize that, while making smart decisions about your Internet use is always a critical part of security, deciding which type of website you visit isn't as important as it once was.

WEIS Recap: Review of “Might Governments Clean Up Malware?”

Richard Clayton wrote on the more interesting papers presented at WEIS.  In his paper “Might Government Clean Up Malware” [pdf] he suggests some possible goverment intervention to aid consumers in cleaning up their computers.  His paper explains the reasons as follows.  
1) ISPs do not have an incentive to act
2) The problem has public dimensions very similar to public health issues
3) The math behind this issue requires someone (the government) to seed the funding for experts to act
I agree with the contention that ISPs do not have incentives to act.  Of the web hosts that I have communicated with not a single one has found it financially rewarding to deal with the problems I highlight.  This really isn’t how it is supposed to work either.  As Clayton points out “in principle the market should deal with ISPs who skimp on abuse activity.”  Which put another way means that those ISPs who do actively clean up infections in their consumer base should have a better image and thus more business.  The market should reward those ISPs who go out of their way to make sure that its customers remain protected.  But as pointed out in many of the papers who grace WEIS and other conferences like it the margins are extremely slim.
Clayton’s paper even references  another paper which makes the claim that a single interaction with a customer by an ISP will eat up all of the profit generated by that customer for the entire year.  (In a footnote he mentions that this may be exaggerated but not greatly so)  
The one issue I have with this paper is that it doesn’t quite cover the issue I’m most concerned about.  And obviously that isn’t a valid criticism of the paper so much as a want from my side.  The paper deals with helping out web “surfers” instead of web masters.  Often the problem that I’m studying involves both levels.  Web sites are infected because the web master’s personal computer was infected and the attacker gathered the login details from there.  So fixing one may in fact help fix the other.  But there is a major difference worth noting.  The paper made a good point in writing about the hesitation of an ISP in engaging with its customers this way.  When margins are thin profit is only acceptable through volume.  So any actions which drive customers away in any number are dangerous.  Accusing customers of infections isn’t always rewarded with gratitude.  Customers can feel angry, ashamed, alienated or all three at once.  It is difficult to find new options for bandwidth provision for many people.  In Cambridge I have my choice between one cable company and two DSL (one who just resells the others at a mark up).  And the change from cable to DSL (or vice versa) comes with considerable costs as well.  But for web hosting providers there isn’t that much cost and there are a lot of choices.  So the dangers of customer alienation for web hosting firms are very very high.
