Not long after the message that Microsoft will stop updating Windows XP from 8 April onwards, after extending it beyond the regular life cycle for over a year already, came the soothing message that malware will be monitored for another year. That may be good news to some, but the fact remains that this is not the same as patching. Remaining on XP leads to a vulnerable state of the desktop, lap top and any other machine running on XP; vulnerable to potential hacks, cyber crimes, becoming part of a botnet, etc. more
When I initiated NNSquad (Network Neutrality Squad), one of my primary concerns was that many seemingly reportable "events" that can occur on the Internet -- and that might seem on their face to be network neutrality "violations" -- might actually be caused by innocent technical issues related to ISP operations, testing anomalies, or misinterpretation of test or otherwise observed data. Analysis of these situations -- which may invoke security and privacy concerns -- can be quite complex, and without a reasonably complete picture of events can also be considerably problematic... more
One of the longstanding goals of network security design is to be able to prove that a system -- any system -- is secure. Designers would like to be able to show that a system, properly implemented and operated, meets its objectives for confidentiality, integrity, availability and other attributes against the variety of threats the system may encounter. A half century into the computing revolution, this goal remains elusive. more
There's often a lot of discussion about whether a piece of malware is advanced or not. To a large extent these discussions can be categorized as academic nitpicking because, at the end of the day, the malware's sophistication only needs to be at the level for which it is required to perform -- no more, no less. Perhaps the "advanced" malware label should more precisely be reattributed as "feature rich" instead. more
Starting in mid-September, one of the largest and most sophisticated DDoS attacks ever targeted the titans of American banking. Initially, victims included Bank of America, JPMorgan Chase, Wells Fargo, PNC Bank, and U.S. Bancorp. In the weeks to come, others would also feel the pain. Websites crashed, customers were unable to make transactions and IT professionals and PR gurus went into panic mode. Leon Panetta, U.S. Secretary of Defense, said the attacks foreshadowed a "Cyber Pearl Harbor." more
A number of security predictions have been doing the rounds over the last few weeks, so I decided to put pen to paper and write a list of my own. However, I have a quite a few predictions so I have listed them over several blog posts. After all, I didn't want to bombard you with too much information in one go! Part three examines the threats associated with data breaches. more
Canada's Communications Security Establishment (CSE) which rarely discloses detail of its activities has taken the "unprecedented step" of releasing one of its own cyber defense tools to the public, in a bid to help companies and organizations better defend their computers and networks against malicious threats. more
How much phishing is there? Where is it occurring, and why? How can it be reduced? I and my colleagues at Interisle Consulting have just published a new study called Phishing Landscape 2020, designed to answer those questions. We assembled a deep set of data from four different, respected threat intelligence providers and enriched it with additional DNS data and investigation. The result is a look at phishing attacks that occurred in May through July 2020. more
If a scholar was to look back upon the history of the Internet in 50 years' time, they'd likely be able to construct an evolutionary timeline based upon threats and countermeasures relatively easily. Having transitioned through the ages of malware, phishing, and APT's, and the countermeasures of firewalls, anti-spam, and intrusion detection, I'm guessing those future historians would refer to the current evolutionary period as that of "mega breaches" (from a threat perspective) and "data feeds". more
The security of the global Default Free Zone (DFZ) has been a topic of much debate and concern for the last twenty years (or more). Two recent papers have brought this issue to the surface once again - it is worth looking at what these two papers add to the mix of what is known, and what solutions might be available. The first of these traces the impact of Chinese "state actor" effects on BGP routing in recent years. more
Building on my last article about Network Assessments, let's take a closer look at vulnerability assessments. (Because entire books have been written on conducting vulnerability assessments, this article is only a high level overview.) What is a vulnerability assessment? more
Recently, the DNS has come under an extensive attack. The so-called "DNSpionage" campaigns have brought to light the myriad methods used to infiltrate networks. These attacks employed phishing, system hopping via key exfiltration, and software zero day exploits, illustrating that many secure networks may not be fully protected. more
I received a spam message the other day that went to my Junk Mail Folder. I decided to take a look at it and dissect it piece by piece. It really is amazing to see how spam crosses so many international borders and exploits so many different machines. Spammers have their own globally redundant infrastructure and it highlights the difficulties people have in combating the problem of it. more
Last week the European Network and Information Security Agency (ENISA), which assists the European Commission and its member states with network and information security issues, published its third Anti-Spam Measures Survey. The survey provides insight into how network operators in Europe are responding to the continued onslaught of email spam. more
Domain Pulse, the yearly get-together of the German-speaking registries of nic.at (Austria), Denic (Germany) and SWITCH (Switzerland) is happening on February 21 and 22 in Vienna. The conference alternates between the countries -- last year it was Switzerland, this year Austria and next year Germany... Domain Pulse covers everything in the domain name arena from management of the DNS, what's happening in each of the ccTLDs, after market and domaining, security threats to the DNS and internet as well as wider issues affecting the internet's development such as internet governance. more
