Until now, the criminals behind malware and phishing have had only 22 generic top-level domain names (TLDs) to abuse -- names like .com, .net or .org. But with hundreds of new TLDs entering the marketplace, e.g. .buzz, .email, and .shop, there are many more targets than ever... What can attackers do with domain names? more»
There has been a recent spate of well publicised Distributed Denial of Service (DDoS) attacks that bring websites down and render them useless, including Evernote and most recently Feedly. In light of this, here are some comments and tips to help companies evaluate and prepare not to be held for ransom or suffer lost reputation and sales as a result. more»
The recent NANOG 61 meeting was a pretty typical NANOG meeting, with a plenary stream, some interest group sessions, and an ARIN Public Policy session. The meeting attracted some 898 registered attendees, which was the biggest NANOG to date. No doubt the 70 registrations from Microsoft helped in this number, as the location for NANOG 61 was in Bellevue, Washington State, but even so the interest in NANOG continues to grow... more»
Over the last few years, there has been an increased effort to modernize the U.S. electric grid. Building a "Smart Grid" has been central in the effort to help utilities better manage their resources, minimize power outages and reduce energy consumption. However, adding more electronic devices and sensors to the grid's network has made it a prime target of cyberattacks, like Distributed Denial of Service (DDoS) attacks, which if successful, could cause wide-spread disruption of services affecting many other sectors. more»
Given that I've written here about the original call for papers for the W3C/IAB "Strengthening The Internet Against Pervasive Monitoring (STRINT)" Workshop and then subsequently that the STRINT submitted papers were publicly available, I feel compelled to close the loop and note that a report about the STRINT workshop has been publicly published as an Internet-draft. more»
Since the end of last year, amplification attacks have been increasingly used by attackers and received heavy media coverage. Everyday protocols not given much thought before, like Network Time Protocol (NTP), can be asked in a very short remote command to send a very large response (list of 600 clients last connected to the NTP server) to a spoofed IP address (the target) by the requestor/attacker. more»
Infamous heavyweight boxer Mike Tyson once said "everyone has a plan until they get punched in the face." As any organization that has faced a cyber attack will tell you, it is a lot like getting punched in the face, and if you're not ready, you might get knocked out. You've likely read recent headlines of major retailers, financial institutions, and now even universities, being hit with data breaches. As some of them have learned the hard way, it's not a question of if your organization will be attacked; it's a question of when. more»
Keynote speaker, and noted security industry commentator, Bruce Schneier (Co3 Systems ) set the tone for the two days with a discussion on how humans name things and the shortcomings of computers in doing the same. Names require context, he observed, and "computers are really bad at this" because "everything defaults to global." Referring to the potential that new gTLDs could conflict with internal names in installed systems, he commented, "It would be great if we could go back 20 years and say 'Don't do that'," but concluded that policymakers have to work with DNS the way it is today. more»
There have been quite a few news stories released over the last 24 hours regarding a wide-scale compromise of 300,00 Internet gateway devices. Here's the executive summary of what happened, how to check if you are vulnerable, and what you can do to fix it... If you use any of these devices, you should check it to ensure your device has not been compromised. more»
There are quite a lot of NTP-amplified denial of service attacks going around at the moment targeting tech and ecommerce companies, including some in the email space. What does NTP-amplifed mean? NTP is "Network Time Protocol" - it allows computers to set their clocks based on an accurate source, and keep them accurate. It's very widely used - OS X and Windows desktops typically use it by default, and most servers should have it running. more»
By design, the Internet core is stupid, and the edge is smart. This design decision has enabled the Internet's wildcat growth, since without complexity the core can grow at the speed of demand. On the downside, the decision to put all smartness at the edge means we're at the mercy of scale when it comes to the quality of the Internet's aggregate traffic load. Not all device and software builders have the skills - and the quality assurance budgets - that something the size of the Internet deserves. more»
BGP. Border Gateway Protocol. The de-facto standard routing protocol of the Internet. The nervous system of the Internet. I don't think I can overstate the importance, the criticality of BGP to the operation of the modern Internet. BGP is the glue that holds the Internet together at its core. And like so many integral pieces of the Internet, it, too, is designed and built on the principle of trust... The folks who operate the individual networks that make up the Internet are generally interested in keeping the Internet operating, in keeping the packets flowing. And they do a great job, for the most part. more»
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»
How can the open standards organizations of the IETF and W3C "strengthen the Internet" against large-scale pervasive monitoring? That is the topic up for discussion at the "Strengthening the Internet Against Pervasive Monitoring (STRINT)" workshop planned for February 28 and March 1, 2014, and jointly sponsored by the Internet Architecture Board (IAB) and the W3C. The workshop is by invitation-only and has a deadline of Monday, January 20, 2014 (by 11:59 UTC) for submission of either position papers or Internet drafts. more»
Most people, even seasoned IT professionals, don't give DNS (the Domain Name System) the attention it deserves. As TCP/IP has become the dominant networking protocol, so has the use of DNS... Due to the reliability built into the fundamental RFC-based design of DNS, most IT professionals don't spend much time worrying about it. This can be a huge mistake! more»
