Routing Attacks on Internet Services

This post was co-authored by Yixin Sun, Annie Edmundson, Henry Birge-Lee, Jennifer Rexford, and Prateek Mittal. In this post, we discuss a recent thread of research that highlights the insecurity of Internet services due to the underlying insecurity of Internet routing. We hope that this thread facilitates important dialog in the networking, security, and Internet policy communities to drive change and adoption of secure mechanisms for Internet routing. more

Cryptographic Catastrophe Theory

Technologists and law enforcement have been arguing about cryptography policy for about 30 years now. People talk past each other, with each side concluding the other side are unreasonable jerks because of some fundamental incompatible assumptions between two conceptual worlds in collision. In the physical world, bank branches have marble columns and granite counters and mahogany woodwork to show the world that they are rich and stable. more

Provoking National Boundaries on the Internet? A chilling thought…

The impact of the recently revealed US government data collection practices may go well beyond the privacy ramifications outlined in the Internet Society's statement: expect a chilling effect on global, resilient network architecture. As governments of other countries realize how much of their citizens' traffic flows through the US, whether or not it is destined for any user or service there, expect to see moves to curtail connections to and through the US. more

IANA: A Tale of Two Fails

The IANA -- Internet Assigned Numbers Authority -- is, functionally, the boiler room of the Internet. Every protocol in use to shovel data from Tallahassee to Timbuktu? Listed there. IP addresses? They are the root from which all addresses flow. Domain names? They are the Source. The entire operation is chock-full of magic numbers, numbers that form and fuel the digital world we use daily. But there are other, lesser-known numbers... It is of PENs that I write today... more

Government Hacking: Proposed Law in the Netherlands

In 2012 I wrote a blog on CircleID called State hacking: Do's and don'ts, pros and cons. In this post I give some thoughts to the concept of a government "hacking back" at criminals. The reason for this was an announcement by the Dutch government that it contemplated law along these lines. The proposed law is now here: the Act Computer Criminality III. more

One Year Later: Lessons Learned from the Target Breach

As the autumn leaves fall from naked trees to be trampled or encased in the winter snow, it reminds us of another year quickly gone by. Yet, for organisations that were breached and publicly scrutinised for their security lapses, it's been a long and arduous year. It was about this time last year that the news broke of Target's mega breach. Every news outlet was following the story and drip feeding readers with details, speculation and "expert opinion" on what happened, why it happened and who did it. more

The New ICANN Emerges in Seoul

With the loud crashing of a traditional drum ceremony and an impromptu electric guitar performance by a young Korean whose rendition of Pachabel has been downloaded sixty million times on YouTube, the 36th meeting of ICANN was kicked off this morning (Korean time) by new CEO Rod Beckstrom and his fellow Directors and assembled one thousand or so participants. ICANN has always been about change, but the atmosphere in Seoul this week is charged with a sense of new challenges and new opportunities. more

Increasing the Strength of the Zone Signing Key for the Root Zone, Part 2

A few months ago I published a blog post about Verisign's plans to increase the strength of the Zone Signing Key (ZSK) for the root zone. I'm pleased to provide this update that we have started the process to pre-publish a 2048-bit ZSK in the root zone for the first time on Sept. 20. Following that, we will publish root zones with the larger key on Oct. 1, 2016. more

Record Number of Malware Variants Detected in Q4 of 2014, Retail/Service Most Targeted

During the 4th quarter of 2014, a record number of malware variants were detected -- an average of 255,000 new threats each day, according a recent report by Anti-Phishing Working Group (APWG). The group further reports that the number of unique phishing reports submitted to APWG during Q4 was 197,252 -- an increase of 18 percent from the 163,333 received in Q3 of 2014. more

How Will Banks Ensure the Safety of Our Money? DDoS Attacks on NL Banks

This week bank costumers of The Netherlands were shocked when they realised that online banking may not be as safe as they thought. Perhaps some were surprised to hear that what they think is money, is nothing but digits, something that does not exist. Their money only exist because we all act as if it exists and accept transactions between each other aided by software run by banks, if they haven't outsourced that function. more

The Distribution of Botnets Since Rustock Went Down

I pulled together some statistics on my collection of botnet statistics for the period of time between Rustock being shut down and Wednesday, April 6. I wanted to see the distribution of botnets per country - now that Rustock is down, which country has the most botnet infections (as measured by unique IP addresses that send us spam)? more

EU Member States Release Report on Coordinated Risk Assessment on Cybersecurity in 5G Networks

European Union Member States published a report on the 'EU coordinated risk assessment on cybersecurity in Fifth Generation (5G) networks'. The report is based on the results of the national cybersecurity risk assessments by all EU Member States. It identifies the main threats and threats actors, the most sensitive assets, the main vulnerabilities, and several strategic risks. more

Report On National Online Cybercrime and Online Threats Reporting Centres

Today I released a report on 'National cyber crime and online threats reporting centres. A study into national and international cooperation'. Mitigating online threats and the subsequent enforcing of violations of laws often involves many different organisations and countries. Many countries are presently engaged in erecting national centres aimed at reporting cyber crime, spam or botnet mitigation. more

OARC-39: Notes on the Recent DNS Operations, Analysis, and Research Centre Workshop

OARC held its fall meeting in Belgrade on October 22 and 23. Here are my impressions of some of the presentations from that meeting... UI, UX, and the Registry/Registrar Landscape - One of the major reforms introduced by ICANN in the world of DNS name management was the separation of registry and registrar functions. The intent was to introduce competition into the landscape by allowing multiple registries to enter names into a common registry. more

Spam from Mobile Networks? Who Woulda Thought…

Mobile networks aren't usually thought of as sources of spam, but a quick look at some of the resources that track spam reveals they actually are. This is counter intuitive at first glance because when most people think of mobile they think of smartphones, and those aren't known to be sources of spam (at least not yet). What's really going on is PCs connected to mobile networks with air cards, or tethered with a smartphone where it's permissible, are the culprits more
