A Nightmare Before Christmas

‘Twas the night before Christmas, when all thro’ the house
Not a sound could be heard, ‘cept the click of a mouse;
The browser was open to Facebook, where else?
As friends posted updates about kittens and elves;

The children were nestled all snug in their beds,
While visions of smartphones danc’d in their heads,
And my wife at her laptop, and I at my desk,
Had just settled our brains for a much needed rest—
When out of my speakers there arose such a clatter,
I suspended a chat to see what was the matter.

To a shiny new window I shifted my gaze,
But then it was gone, leaving me in a daze.
The glare of the screen and the whir of the drive,
Made me think I was safe, and my PC alive;

When, what to my wondering eyes should appear,
But a dialog box, which just filled me with fear,
With a little old message, so simple and spare,
I knew in a moment it must be malware.

“Your files are hostages, don’t start to doubt,
And you’ll pay us a ransom to get them back out.”
“My Word docs, my e-mails, my photos and Quicken,
appointments and bookmarks and music, all missin’!”

“To Facebook Security, to the search engines too,
I need a solution! Please, someone, come through!”

As soon as it happened, I asked myself why,
And I thought it all through, then I said with a sigh,
“You never did update your browser or Flash,
and you still click on links that offer free cash.
You use anti-virus that’s three years too old,
and you click through the warnings, no matter how bold.”

But now it was too late to beat up myself,
I needed the help of some friendly elf.
And then in a twinkling, I saw in a post
Just what to do if your files were toast.

As I followed directions, my fingers were crossed,
I just hoped and prayed that all was not lost.
An hour passed, and then it was three,
I rebooted again, and my files all were free!

Embarrassed, I posted my tale on my Wall,
to serve as a warning for friends one and all.
“You’re lucky,” said one, “some malware is worse.”
Lucky or not, this stuff is a curse.

So with that I learned a good lesson or two
about patching my software and thinking things through
before clicking on links that just don’t make sense
and backing up files before things get tense.

Now I leave you with this as I turn out my light—
A safe Christmas to all, and to all a good night.

Cybersecurity data sharing: you’re doing it wrong

One aspect of cybersecurity that StopBadware routinely emphasizes as essential to collective defense against malware is data sharing. As we’ve pointed out in the past, there are few incentives favoring, and many opposing, the sharing of malware attack-related data among private ecosystem participants like ISPs and web hosting providers, which makes tackling malware threats collaboratively prohibitively difficult. Apparently, data sharing problems are on Congress’s mind as well. Last week, the House Intelligence Committee considered and passed HR 3523, the Cyber Intelligence Sharing and Protection Act of 2011, one of Congress’s most visible efforts to confront computer security issues, which specifically addresses the sharing of “cyber threat intelligence”. Unfortunately, the bill’s sponsors appear to perceive all forms of cyber threat intelligence — everything from a RSA-style infiltration to a blind SQL injection — as (a) presumptively classified and in desperate need of control and (b) something from which private companies like ISPs and web hosting providers need protection.

First off, it seems the height of ridiculousness to assert that the intelligence community requires Congress’s special permission to share information with important private sector infrastructure companies (like telcos and ISPs) if it possesses information that demands action. Federal intelligence and law enforcement agencies share, and are certainly not statutorily barred from sharing, malware- and cyberattack information with private parties already; specifying a system of temporary security clearances presumes that the disclosure of much of such information will place the national security of the United States in jeopardy. So either the status quo is somehow a dangerous threat to our nation, or the bill’s solution is in search of a problem.

Moreover, the bill fails to address the actual collective action problem at the core of malware data sharing. By allowing companies to specify how malware data is shared with other private parties, the broader cybersecurity community, whose operations dwarf those of the federal government, need not be materially enriched in any way. In essence, the government seeks to establish a cybersecurity clearinghouse that need enrich only itself. The government should provide additional resources and tools to companies willing to make common cause with one another in the cybersecurity fight, not reward companies that share data — which is very loosely defined by the bill, is exempt from the Privacy and Freedom of Information Acts, and may include PII and customer-created content — with it and it alone.

Secondly, the bill takes the extraordinary step of immunizing all participating companies from any criminal or civil liability as a result of sharing information or failing to act on information they receive. Content providers like ISPs and hosting providers are already immunized for failure to take action on malware reports under section 230 of the CDA as courts have interpreted the law; further grants of immunity should be conditioned on at least a minimal standard of accountability for gross negligence in the handling of such data.

The Washington Post has reported that in response to objections from privacy advocates and concerns from the White House, the bill has been amended to include protections against coercive data sharing practices and oversight by the intelligence community Inspector General. It’s a step in the right direction, but does little to cure the bill’s other flaws, including facilitating sharing of irrelevant, private information and use of data submitted for purposes other than cybersecurity defense. While increased sharing of cybersecurity information within the Internet ecosystem is a laudable goal, Congress should seriously consider an approach that emphasizes data sharing within the private sector, and better protect the general public from abuse.

PROTECT-IP, SOPA, and the real threat to national security

A substantial portion of the broader technology policy community has stepped up its efforts to raise awareness of the current debate surrounding the PROTECT-IP Act, pending in the Senate, and the Stop Online Piracy Act (SOPA), pending in the House. Our friends over at the Center for Democracy and Technology have produced an excellent summary of opposition views from a broad range of interested parties, including public-interest advocates like the EFF and ACLU, law professors, and the Global Network Initiative. We at StopBadware are squarely opposed to both bills.

Others have identified the manifold ways in which the bills violate traditional norms of notice, disregard procedural and substantive due process, seriously undermine hosting provider immunity under the CDA and DMCA, and threaten the health of the global Domain Name System. The House bill's co-sponsors, Reps. Lamar Smith (R-TX) and John Conyers (D-MI), seem oblivious to the the threat it poses, claiming it addresses "critical intellectual property issues that relate to national security, public health and safety, and the expansion of respect for intellectual property abroad".

To claim that the bill will meaningfully improve America's national security posture is preposterous on its face — one must conflate risks to U.S. copyright holders with the national interest writ large — and, with the exception of rogue pharmacies, very few infringing websites facilitate threats to public health. But let's take SOPA’s sponsors at their word for a minute and consider it a given that they want to make a serious attempt to address these important issues. Why wouldn't they target websites distributing badware instead?

Let me be clear: even if, ceteris paribus, PROTECT-IP and SOPA targeted malware distributors rather than copyright infringers, they'd still be lousy bills. In all of its work, StopBadware strives to encourage private industry and regulators to respect the free speech and due process rights of Internet users, including web masters.

That said, Congress could do much more than it has to give the security community the power to take action (under strict judicial supervision) against operators of badware websites. Malware is indisputably a national security and public health issue. As we've mentioned before in The State of Badware, criminals can set up, co-opt, and maintain badware websites because control of the infrastructure that sustains them is split among webmasters, web hosting providers, ISPs, registrars, registries, and national governments. While security researchers can collect evidence of badware behavior on websites and inform appropriate parties (see our Best Practices for Badware Reporting for more on that), they have little power to compel these parties to take these reports seriously.

Imagine if Congress were to empower security researchers with civil causes of action like the ones PROTECT-IP and SOPA grant to copyright holders. For example, Congress might attempt any or all of the following:

  • require web hosting providers to disable access to malicious content they host;
  • require DNS providers to suspend nameserver services for domain names used primarily to spread badware;
  • require US-based registrars to suspend registrations of such domain names;
  • require US-based registries to revoke registrations of such domain names.

Drafting a statute like the above — one that respects issues of standing, free speech, and due process — would definitely pose a major challenge. (I suspect that's why Protect-IP and SOPA's sponsors made no attempt to do so.)  Practically speaking, bringing successful challenges against recalcitrant infrastructure operators could be an expensive, time-consuming endeavor. But it might produce better results than the status quo.

Why? A primary effect of the Computer Fraud and Abuse Act (18 U.S.C. 1030) is to make it a crime to infect computers with malware. From this we can infer that computer owners have a right to be free of malware. In practice, as we know, pursuing responsible parties, or even determining with certainty who they are, exceeds prosecutors' technical and logistical resources. It brings to mind an ancient and well-loved principle of equity — that there can be no right without a remedy. Congress should seriously consider creating remedies that support this right and enforce it against entities who are otherwise complicit.

An approach like the one I've sketched out isn't without its pitfalls. U.S. courts have very little experience with the malware threat landscape, and judicially sanctioned interventions against malware distributors have been chiefly limited to large botnet takedowns, frequently with the assistance of security researchers and large corporations. (See our write-up on the role of government and private parties in the Coreflood takedown here.) Most day-to-day badware website takedowns occur through private persuasion, not judicial compulsion.

Yet given the growth and persistence of badware websites, the security community should take a long, hard look at the existing system of badware report handling and ask itself if private self-regulation has been effective at stemming the tide of the malware onslaught. Consider the global WHOIS system, which was theoretically intended to link domain names and IP addresses to the people responsible for their use (or abuse). Any badware website reporter will tell you that WHOIS results are rarely the end of an inquiry, and frequently contain outdated or outright fraudulent information. This makes investigation much harder, and is still no guarantee that a complaint will receive an airing from any party, much less an appropriate resolution. In short, we have an accountability problem: one can cry 'malware' all one likes, and no one has to listen.

Not so in the courts. If fraud, deception, negligence, and organized crime are properly the province of the judiciary in meatspace, why not in cyberspace?

I present this image of government regulation to the cybersecurity community as an invitation to to prove to the U.S. government, and to the world, that it can bridge this trust and accountability gap themselves. StopBadware has always sought to help embody the change we seek in the Internet through voluntary, collaborative efforts with industry experts (as in our badware reporting and web hosting best practices work). But bills like PROTECT-IP and SOPA should remind us that when the Internet community fails to act, intrusive and ill-informed legislation may seek to ‘solve’ our problems for us.

In short, we agree with others in our community who have come out forcefully against PROTECT-IP and SOPA. Not only does it fail to solve the problems it identifies (and creates massive new ones), but reflects completely misguided thinking on the root causes of those problems and ignores approaches that might solve them. SOPA’s sponsors want to improve cybersecurity by giving copyright holders a license to 'kill' infringers with no notice. We'd have them do it by giving malware victims their day in court.

StopBadware gains two new Partners: Sophos and Tucows

It’s December already! We’re not really sure how that happened, but we have good news to share, so we’ll postpone our calendar confusion. Over the past year and change, we’ve had the pleasure of working with a number of distinguished security experts and respected companies. Today we’re happy to report that two of those respected companies have decided to officially join the StopBadware Partner community: we happily welcome Sophos, a well-known leader in IT security, and Tucows, wholesale domain name registrar and a recognized leader in the Internet industry since 1994.

Both companies have long been active in the security space, and recently they’ve contributed knowledgeable members to our Malware Reporting Working Group, which advised us in the development of our Best Practices for Reporting Badware URLs. It’s part of our culture at StopBadware to seek out organizations and individuals who are committed to sharing knowledge and taking a community approach to security. Tucows and Sophos definitely fit that bill: we’ve benefited from working with both companies in the past, and we’re excited to further our collaboration with each of them as we prepare to ring in 2012.

Collaborative survey on compromised websites

If you've been following us this past week, you may have seen a few blips about a survey we're conducting together with Commtouch on compromised websites. It's fairly common knowledge at this point that legitimate websites are frequently compromised by malicious actors and used to host malware. Infosecurity Magazine yesterday talked with Commtouch about a recent scam that used spam email campaigns and social engineering  to convince users that their "Delta airlines booking was rejected." The emails used compromised sites as destination URLs to complete the scam and infect end users' computers.

It would be a great Thanksgiving present for us to go even a day without seeing dozens of legitimate sites that have been compromised without their owners' knowledge. Unfortunately, we're not there yet, but one of the best defenses the Web ecosystem has is information—and the sharing of that information. As one of our community forum moderators says, "Silence is a hacker's best friend," and shared knowledge is one weapon we'll brandish readily.

With that, we'll get to the point: if you're a site owner whose site has been compromised, please take a minute or so to answer a few quick questions about what happened, how you found out, and how your site was used. We're not collecting any identifying information (e.g., your name, email, or IP address), just the answers you provide and the date. A few fast answers about your experience can make a difference in the way we and others help defend the Internet ecosystem from badware and its distributors. 

Take the survey here!

A very happy and safe Thanksgiving to all of you in the U.S., and an equally happy and safe non-Thanksgiving to everyone outside the U.S. We're grateful for a lot of things this holiday, and the outstanding participation, collaboration, and feedback we receive from our community is at the top of our list.

Supporting a voluntary code for ISPs

Earlier this week, we submitted comments in response to a request for information from the U.S. Departments of Commerce and Homeland Security. The topic was development of a voluntary code of conduct for industry, particularly ISPs, to help address botnets. The RFI follows similar national efforts in Australia, Germany, and Japan.

StopBadware, of course, already helps to reduce the threat of botnets by helping to prevent and clean up websites that deliver malware to end users. That said, there’s much still to be done, and we support the approach broadly proposed by the government’s RFI. Here’s a brief summary of our comments:

  • Prevention of malware infection is multi-faceted, including everything from cleaning up badware websites to educating end users. We detail several of these facets, highlighting examples of effective tools and approaches within each.
  • When discussing industry-driven initiatives, it is critical to look to users’ needs. We use our experience working with owners of compromised websites to suggest how industry can effectively meet the needs of users whose devices have been infected.
  • A voluntary code of conduct for ISPs is a good step, but there are several opportunities where pooled resources could do more than each industry player working independently. We suggest three such cases and argue that independent non-profit organizations are better suited than for-profit companies or government to offer such resources.

Here’s the full set of comments. Please let us know if you have any additional thoughts on this topic!

20 providers. 10 countries. 5 continents. 1 goal.

Two months after its launch in August, our We Stop Badware™ Web Host program has garnered 20 hosting providers from around the world who have pledged to protect their networks and their customers by responding decisively to badware reports. We’re impressed and encouraged by the diversity of the providers who have voluntarily pledged to implement policies and procedures consistent with our best practices. We Stop Badware™ now boasts participating providers from 10 countries on 5 continents, and participants include everyone from small providers who pride themselves on uncompromising security to several of the largest web hosting companies in the world. We at StopBadware know what a crucial role web hosting providers play in both badware prevention and remediation; in fact, we’ve submitted badware reports to several of these companies ourselves, so in some cases we can vouch firsthand for their responsiveness. We commend these providers for their commitment to security and collaboration.

We Stop Badware™ Web Host participants:

13StudioHost Portugal
Blacknight Ireland
Coolhandle Hosting United States
Daycohost Venezuela
DiscountASP.Net United States
Host TugaTech Portugal
InlandHost.NET India
InNucleo, Alojamento Web Portugal

*StopBadware Sponsoring Partner

**Previously recognized for exemplary responses to badware reports

A few points we’ll reinforce, at (acceptable) risk of sounding like a broken record: 

Websites are prime attack vectors. Hosting providers who address malware on websites within their zones of control protect countless users and additional website owners from infection. Self-evident? Perhaps. Still, we’ve been aware from the beginning that web hosting providers operate within an extraordinarily competitive market and are often subject to diverse legal constraints. We also recognize that hosting providers are frequently the first to feel the ire of site owners whose domains have been infected, blacklisted, or taken down. In a competitive market, taking responsible action shouldn’t ever mean losing business. For this reason, we publicly acknowledge and commend web hosting providers who commit to doing their part to stop badware, and we work hard to educate site owners about badware prevention and remediation. 

On that note, this one’s for the site owners (and future site owners): your web hosting provider matters, and not just to you. Hosting providers who take action to limit malicious content on their networks benefit you individually—whether your site is currently infected or not—and the Internet as a whole. Security isn’t just a consideration; it’s a necessity. Is your hosting provider on this list? If not, why? 

StopBadware’s Best Practices for Web Hosting Providers, on which the We Stop Badware™ Web Host program is based, are designed to be implementable by hosting providers of every size and type. To address concerns about legal liability for malicious content on providers’ networks, we commissioned a legal whitepaper from the renowned Berkman Center for Internet & Society at Harvard University. The white paper, the best practices, and additional resources for web hosting providers are available at http://www.stopbadware.org/best-practices/web-hosting-providers. Learn how to sign up for the We Stop Badware™ Web Host program here. Free resources for site owners who want to prevent or remove badware on their websites are available here

New best practices for reporting badware URLs

We’re happy to announce today the public release of our second best practices document: Best Practices for Reporting Badware URLs. These best practices lay out steps that individuals and organizations can follow to effectively report badware URLs to the parties best able to address them. 

The seeds for our new set of best practices were sown during the development of our Best Practices for Web Hosting Providers earlier this year. A common question during our Web Hosting Working Group’s tenure was, “What about best practices for reporting?” The reasoning behind the question was simple: after spending several months determining the most responsible and effective ways for web hosting providers to respond to badware reports, it seemed eminently sensible to develop a complementary set of best practices for reporters so as to shape a clear path all the way from badware detection to resolution. 

After a summer full of discussion with another brilliant and distinguished cross-industry working group, we have a new set of Practices that we feel we can confidently say are “best” when it comes to reporting badware URLs. Our best practices divide the reporting process into four main stages: determining report targets, identifying contact information, assembling contents, and delivering the report. Best practices are laid out for each stage, along with specific steps for report escalation should initial reports fail to receive a satisfactory response. It’s our intention and our hope that the final document will promote reporting in a way that’s useful to hosting providers and other report recipients while offering reporters both clear instruction and flexibility.

Last month, we wrote that “a full 67% of the URLs we reported [in accordance with the reporting best practices] were cleaned up, many within a short time.” Happily, that statistic is holding steady as our sample size (and our reporting experience) increases; moreover, when the report recipient acknowledged receipt of the report, the badware URL cleanup rate jumped to 75%. Our Best Practices for Reporting Badware URLs take a different approach than the Best Practices for Web Hosting Providers, but the goal, of course, is the same: to get badware URLs noticed, acknowledged, and either cleaned up or taken down—quickly and responsibly.

You can download a copy of StopBadware’s Best Practices for Reporting Badware URLs here. Today’s press release is available here.

Why Finland has so little malware

Tim Rains from Microsoft’s Trustworthy Computing group recently posted an excellent series of short blog posts titled Lessons from Some of the Least Malware Infected Countries in the World. Tim asked local security experts in each of these countries why they believed their nations were consistently lower than most on Microsoft’s “Computers Cleaned per Mille (CCM)” measure. A brief summary of the findings can be found here, but I encourage you to read the six part series. (None of the individual parts are more than a couple pages of text.)

One interesting tidbit is that there is not necessarily a correlation between low PC infection rates (as measured by CCM) and low rates of badware websites (as measured by either malware hosting sites per thousand hosts or drive-by download sites per thousand hosts). This isn’t terribly surprising, I suppose. Although the basic goals of prevention, mitigation, and remediation are the same for PCs and websites, the practical implementations are quite different. Germany, for example, has a national center for providing remediation of bot-related malware detected on consumer PCs. No such national resource exists for addressing compromised websites. (It’s a good thing StopBadware and BadwareBusters.org are here, isn’t it?)

Perhaps the most important lesson, though, is that strongly coordinated efforts to educate the public, notify victims, engage providers, and coordinate response seem to be highly correlated with low infection rates. We can all draw inspiration from that as we work to strengthen these efforts within and across our own areas of focus.
