DoT and DoH Guidance: Provisioning Resolvers

As part of a larger effort to make the internet more private, the IETF defined two protocols to encrypt DNS queries between clients (stub resolvers) and resolvers: DNS over TLS in RFC 7858 (DoT) and DNS over HTTPS in RFC 8484 (DoH). As with all new internet protocols, DoT and DoH will continue to evolve as deployment experience is gained, and they're applied to more use cases. more

The Other Side of Security

The Denver edition of Security BSides took place a few weeks ago in a garage turned art gallery on the far end of Denver's emerging Santa Fe Arts District, right on the border between historic working-class neighborhoods and a rambling wasteland of building supply warehouses. ... The presentation I enjoyed most was "Top 10 Ways IT is Enabling Cybercrime," presented by Daniel J. Molina from Kaspersky Labs. He described how quickly threats are evolving, how many new threats are appearing every day, and explained that the targets aren't always who you'd expect. more

Outlawing Botnets

The European Commission is apparently considering the promulgation and adoption of a directive that would, at least in part, criminalize botnets. As I understand it, the premise behind adopting such a directive is that since botnets are capable of inflicting "harm" on a large scale, we need to separately criminalize them. I decided to examine the need for and utility of such legislation in this post. more

Twitter, DDoS and the Motivations Behind the Attack

As we all know by now, last week, on Thursday, August 7, Twitter was hit with a denial-of-service attack that took it down for several hours. Other social networking sites like Facebook, LiveJournal, Youtube and Blogger were also hit. They managed to repel the attack although Facebook was not quite as successful as the other larger players. The theory floating about at the moment is that this was a politically oriented play designed to target one guy: a blogger. We are nearing the 1-year anniversary of a the Russian/Georgian 2008 war. There is a pro-Georgian blogger by the username of "Cyxymu" who had accounts on all of these services. more

The Next New Media: Typewriters and Handwritten Letters

Who would have thought that typewriters and handwritten letters would ever be back in fashion? But back in 2013 it was reported that Russia was buying large quantities of typewriters. When this was further investigated the country denied that this was for security reasons. Since the Snowden revelations there has been a further rush on typewriters, both by government officials and by a range of, mainly corporate, businesses. more

Hackers in Possession of Over 312K Files, 516GB Financial Data of Some of World’s Largest Companies

A report broke today revealing hackers have successfully breached a German internet infrastructure firm that provides services to several large companies, including Ericsson, Leica, Toshiba, UniCredit, British Telecom, Hugo Boss, NH Hotel Group, Oracle, Airbus, Porsche, and Volkswagen. more

The Antivirus Uncertainty Principle

The antivirus industry has been trying to deal with false positive detection issues for a long, long time - and it's not going to be fixed anytime soon. To better understand why, the physicist in me draws an analogy with Heisenberg's Uncertainty Principle - where, in its simplest distillation, the better you know where an atom is, the less likely you'll know it's momentum (and vice versa) - aka the "observer effect". more

One Third of Companies Employing Staff to Monitor Content of Outbound Email, According to Survey

A recent survey of US companies conducted by Proofpoint has found companies increasingly concerned over data leaks via emplyee misuse of email, blogs, social networks, multimedia channels and text messages. From the report: "[A]s more US companies reported their business was impacted by the exposure of sensitive or embarrassing information (34 percent, up from 23 percent in 2008), an increasing number say they employ staff to read or otherwise analyze the contents of outbound email (38 percent, up from 29 percent in 2008). The pain of data leakage has become so acute in 2009 that more US companies report they employ staff whose primary or exclusive job is to monitor the content of outbound email (33 percent, up from 15 percent in 2008)." more

A Cancerous Computer Fraud and Misuse Act

As I read through multiple postings covering the proposed Computer Fraud and Misuse Act, such as the ever-insightful writing of Rob Graham in his Obama's War on Hackers or the EFF's analysis, and the deluge of Facebook discussion threads where dozens of my security-minded friends shriek at the damage passing such an act would bring to our industry, I can't but help myself think that surely it's an early April Fools joke. more

Why I Wrote ‘Thinking Security’

I have a new book out, Thinking Security: Stopping Next Year's Hackers. There are lots of security books out there today; why did I think another was needed? Two wellsprings nourished my muse. (The desire for that sort of poetic imagery was not among them.) The first was a deep-rooted dissatisfaction with common security advice. This common "wisdom" -- I use the word advisedly -- often seemed to be outdated. Yes, it was the distillation of years of conventional wisdom, but that was precisely the problem: the world has changed; the advice hasn't. more

Vietnam Primary Source of Spam in November

Vietnam is now responsible for more than 10% of the worlds spam, according to threat analysis from managed security firm, Network Box. November saw malware threat levels remain consistently high with Vietnam taking the number one spam spot from last month’s chart topper, Brazil. more

China: Is It Our Cyber Defense Red Herring?

There are thousands of articles perpetuating the claim that China is out to get us on the Internet. And yet, all these discussions are begging the question, is it China attacking? Also, are they even the "usual suspects"?
While I can point to real facts of China making active use of information warfare, cyber warfare, or whatever else you choose to call it (such as the release of 0 days being patched by Microsoft and originally reported by the Taiwanese government, search Microsoft's site), I can also point to Germany (intelligence Trojan horse), the US (The Farewell Dossier) and other countries such as North Korea (without much detail, so questioned)... more

In Which We Consider the Meaning of ‘Authorized’: GIVAUDAN FRAGRANCES CORPORATION v. Krivda

What does authorized access mean? If an employee with authorized access to a computer system goes into that system, downloads company secrets, and hands that information over to the company's competitor, did that alleged misappropriation of company information constitute unauthorized access? This is no small question. If the access is unauthorized, the employee potentially violated the Computer Fraud and Abuse Act (CFAA) (the CFAA contains both criminal and civil causes of action). But courts get uncomfortable here. more

Routing Security - Getting Better, But No Reason to Rest!

In January 2018, I looked back at 2017 to figure out how routing security looked globally and on a country level. Using the same metrics and methodology, I've recently taken a look at 2018 to see if we're making improvements. The good news is, it seems like the routing system is doing better! But there is still much work to be done. Using BGPStream.com, a great public service providing information about suspicious events in the routing system, I analyzed the number of incidents... more
