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
Every year those in the security industry are bombarded with various cyber security predictions. There's the good, the bad and the ugly. Some predictions are fairly ground breaking, while others are just recycled from previous years -- that's allowed of course if the threats still stand. In part one of my predictions I looked at the malware threats, so let's take a look at big data and the cloud for part two. more
Distributed Denial of Services (DDoS) attacks have been the frustration of information technology professionals for many years. When asked, most tell you they wish their internet service providers (ISPs) would simply provide them "clean pipes" all the time and take care of DDoS attacks upstream before they ever get to them. Unfortunately, the resources (equipment and personnel) necessary to clean Internet connections all the time are very expensive and come with several downsides. more
Google today announced an initiative called "Project Shield", aimed at using its infrastructure to protect free expression online. "The service currently combines Google's DDoS mitigation technologies and Page Speed Service (PSS), which allow websites to serve their content through Google to be better protected from DDoS attacks." Google is currently seeking "trusted testers" and people with sites that serve media, elections and human rights-related content. more
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
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 recent attacks on the DNS infrastructure operated by Dyn in October 2016 have generated a lot of comment in recent days. Indeed, it's not often that the DNS itself has been prominent in the mainstream of news commentary, and in some ways, this DNS DDOS prominence is for all the wrong reasons! I'd like to speculate a bit on what this attack means for the DNS and what we could do to mitigate the recurrence of such attacks. more
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
Bruce Schneier is a famous cryptography expert and Orin Kerr a famous cyberlaw professor. Together they've published a law journal article on Encryption Workarounds. It's intended for lawyers so it's quite accessible to non-technical readers. The article starts with a summary of how encryption works, and then goes through six workarounds to get the text of an encrypted message. more
An international group of more than 360 cyber threat intelligence researchers from over 40 countries have joined forces to help the medical sector amid the COVID-19 crisis. more
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
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
A few days ago, CAUCE published a blog post entitled "Epsilon Interactive breach the Fukushima of the Email Industry" on our site, and the always-excellent CircleID. A small coterie of commenters was upset by the hyperbolic nature of the headline. Fair enough, an analogy usually has a high degree of probability that it will fail, and clearly, no one has died as a result of the release of what appears to be tens of millions of people's names and email addresses. But, the two situations are analogous in many other ways, and here's why. more
The Conficker worm will be active again on April 1st, according to an analysis of its most recent variant, Conficker.C, by the net security firm CA. This malicious piece of software, also known as Downup, Downadup and Kido, spreads among computers running most variants of the Windows operating system and turns them into nodes on a multi-million member ‘botnet’ of zombie computers that can be controlled remotely by the worm’s as yet unidentified authors. more
I read, with some small amount of discomfort, an article by Bill Brenner on CSO Online, wherein he interviewed several other CSOs and other "Security Execs" on their opinions on the firing of Pennsylvania CISO Robert Maley. For those who haven't heard about this, Mr. Maley was fired for talking about a security incident during the recent RSA conference without approval from his bosses. more
