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»
In the wake of increasingly lenient bring your own device (BYOD) policies within large corporations, there's been a growing emphasis upon restricting access to business applications (and data) to specific geographic locations. Over the last 18 months more than a dozen start-ups in North America alone have sprung up seeking to offer novel security solutions in this space - essentially looking to provide mechanisms for locking application usage to a specific location or distance from an office, and ensuring that key data or functionality becomes inaccessible outside these prescribed zones. more»
Kenzie is a security researcher who has registered numerous domain names that are typographic errors of well-known trademarks (e.g., rnastercard, rncdonalds, nevvscorp, rncafee, macvvorld, rnonster, pcvvorld). He points the domain names to the actual sites in question (e.g., rncdonalds points to mcdonalds.com), but he is looking to demonstrate how these typo domains are used for "social engineering" attacks. more»
Tonight begins the third annual SIP Network Operators Conference (SIPNOC) in Herndon, Virginia, where technical and operations staff from service providers around the world with gather to share information and learn about the latest trends in IP communications services - and specifically those based on the Session Initiation Protocol (SIP). Produced by the nonprofit SIP Forum, SIPNOC is an educational event sharing best practices, deployment information and technology updates. Attendees range from many traditional telecom carriers to newer VoIP-focused service providers and application developers. more»
The Internet Corporation for Assigned Names and Numbers (ICANN) has released new guidance concerning the reporting and disclosure of bugs that affect the Domain Name System, including information of how ICANN itself will behave in response to vulnerabilities. Until recently, ICANN, which is responsible for maintaining the root domain servers at the heart of the DNS system, had no specific guidelines for the reporting of vulnerabilities, leaving responsible disclosure protocols up to the researchers who discovered the bug. more»
The headlines out of ICANN's meeting in Beijing may be all about new domains, but it is the quiet, systemic evolution of ICANN itself that holds the greatest promise for Internet users globally. ICANN President Fadi Chehadé opened the meeting by announcing that it was ICANN's "season to evolve," and setting forth a series of programs, restructuring efforts and policy initiatives intended to make ICANN more responsive to the needs of its stakeholders, and by extension, to the needs of all Internet users, everywhere in the world. 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»
Three vectors were exploited in the recent DDoS attack against Spamhaus: 1) Amplification of DNS queries through the use of DNSSEC signed data; 2) Spoofed source addresses due to lack of ingress filtering (BCP-38) on originating networks; 3) Utilisation of multiple open DNS resolvers While. 1) is unavoidable simply due to the additional data that DNSSEC produces, and 2) "should" be practised as part of any provider's network configuration, it is 3) that requires "you and I" ensure that systems are adequately configured. more»
There has been plenty of buzz and chatter on the Internet recently concerning a very large DDoS attack against CloudFlare, with coverage on their blog, the New York Times, and the BBC, among many others. While attacks of this nature are certainly nothing new, the scale of this attack was surprising, reported to hit 120Gbps. For a sense of scale, your average cable modem is only about 20Mbps, or about 0.016% of that bandwidth. more»
Yesterday Verisign sent ICANN a most interesting white paper called New gTLD Security and Stability Considerations. They also filed a copy with the SEC as an 8-K, a document that their stockholders should know about, It's worth reading the whole thing, but in short, their well-supported opinion is that the net isn't ready for all the new TLDs, and even if they were, ICANN's processes or lack thereof will cause other huge problems. more»
If you haven't been reading the news of late, venerable anti-spam service Spamhaus has been the target of a sustained, record-setting Distributed Denial-of-Service (DDoS) attack over the past couple of weeks... Of course, bad guys are always mad at Spamhaus, and so they had a pretty robust set-up to begin with, but whoever was behind this attack was able to muster some huge resources, heretofore never seen in intensity, and it had some impact, on the Spamhaus website, and to a limited degree, on the behind-the-scenes services that Spamhaus uses to distribute their data to their customers. more»
For those of you interested in IPv6 and/or DNSSEC, we'll have a live webcast out of the Internet Society's ION Singapore conference happening tomorrow, March 28, 2013, starting at 2:00pm Singapore time. more»
As attack vectors go, very few are as significant as obtaining the ability to insert bespoke code in to an application and have it automatically execute upon "inaccessible" backend systems. In the Web application arena, SQL Injection vulnerabilities are often the scariest threat that developers and system administrators come face to face with (albeit way too regularly). more»
Sender Address Validation and Authentication (SAVA) is the silver bullet. It will send to Cyberia all dark forces that make us shiver when we make a purchase on the internet, pose a threat to our very identities and have made DDoS a feared acronym. Some of you will remember the heated debates when Calling Line Identification (CLID) was first introduced in telephony. Libertarians of all stripes called passionately to ban such an evil tool... more»
As noted in my first article of this series (see part one, two and three), security and reliability encompass holistic network assessments, vulnerability assessments and penetration testing. This month I'd like to go deeper into penetration testing; however, first, let's go back for a quick refresh before getting started. more»
