Behind the Smoke Screen of Internet and International Infrastructure

In my recent write-up I start by discussing some recent threats network operators should be aware of, such as recursive DNS attacks. Then, a bit on the state of the Internet, cooperation across different fields and how these latest threats with DDoS also relate to worms and bots, as well as spam, phishing and the immense ROI organized crime sees. I try and bring some suggestions on what can be done better, and where we as a community, as well as specifically where us, the "secret hand-shake clubs" of Internet security fail and succeed. Over-secrecy, lack of cooperation, lack of public information, and not being secret enough about what really matters. more

Foreign Hackers Attack Canadian Government

An unprecedented cyberattack on the Canadian government also targeted Defence Research and Development Canada, making it the third key department compromised by hackers, CBC News has learned. ... While there is no definitive proof, of course, that China was behind these attacks, there is a lot of circumstantial evidence that points in that direction. China (allegedly) has a long history of engaging in espionage activities in order to gain access to information. In the United States, this is sometimes referred to as cyber warfare, but I think that cyber espionage is a better choice of terms. more

Day 30: Kaminsky DNS Bug Disclosure

In a highly anticipated presentation, Internet security researcher Dan Kaminsky today gave details of the much talked about Domain Name System (DNS) vulnerability issue which has been intensely covered since it was publicly announced a month ago on Jul 8th. Although original plans entailed keeping the bug details undisclosed for 30 days in order to allow for necessary security patches to be implemented around the world, details of the bug were eventually leaked-and-confirmed 13 days after its public announcement. Even so, just hours ago in jam-packed ballroom during the Black Hat conference, Kaminsky delivered his 100-plus-slide presentation detailing the DNS flaw that, if exploited, could potentially "destroy the Web". more

Considering a Vulnerability Disclosure Program? Recent Push Raises Questions for General Counsel

Several years ago, vulnerability disclosure programs, also called "bug bounty" programs, were novel and eyed with suspicion. Given sensitivities and potential liabilities, companies are wary of public disclosure and hackers seeking to exploit research. When a hacker presented a flaw to a company, the company was more likely to be concerned about taking legal action than making a public announcement or offering a reward. That is changing. more

Comcast Announces Completion of DNSSEC Deployment

Comcast, a leading ISP in the U.S., has fully deployed Domain Name System Security Extensions (DNSSEC) according to a company announcement today. Jason Livingood, Comcast's Vice President of Internet Systems writes: "As of today, over 17.8M residential customers of our Xfinity Internet service are using DNSSEC-validating DNS servers. In addition, all of the domain names owned by Comcast, numbering over 5,000, have been cryptographically signed. All of our servers, both the ones that customers use and the ones authoritative for our domain names, also fully support IPv6." more

Why the 1# Vulnerability for Cyber Attacks Will Be Apathy

Everyone has heard of the cyber security attacks on Target (2013), Home Depot (2014), Neiman Marcus (2014), Sony Pictures (2014), and the United States' second-largest health insurer, Anthem (reported February 2015), but have you heard of the security breaches for Aaron Brothers, Evernote (denial of service attack), P.F. Chang's China Bistro, Community Health Services, Goodwill Industries, SuperValu, Bartell Hotels, Dairy Queen, U.S. Transportation Command contractors, and more. more

KnujOn Releases New Security, Abuse and Compliance Report

We have just issued a new report detailing abuse of the Domain Name System and Registrar contract compliance issues. The report specifically discusses several items including: Registrars with current legal issues; Illicit Use of Privacy-Proxy WHOIS Registration; A study on the contracted obligation for Bulk WHOIS Access; and more. more

NANOGGING

There are many network operator group meetings being held these days. Even in the backwater of the South Pacific where I live there is now AUSNOG, and NZNOG is just next door in New Zealand. We now have MENOG in the Middle East and AFNOG in Africa. The original NOG was the North American Network Operators Group (NANOG), and they have the T-Shirts to prove it! NANOG meets three times a year, and I attended NANOG 41 in October 2007. NANOG meetings cover a broad variety of topics, from operational tools, measurement, and peering practices through to a commentary on the state of the Internet industry. Here are my impressions of the meeting. more

Traceability

At a recent workshop on cybersecurity at Ditchley House sponsored by the Ditchley Foundation in the U.K., a primary topic of consideration was how to preserve the freedom and openness of the Internet while protecting against the harmful behaviors that have emerged in this global medium. That this is a significant challenge cannot be overstated... That these harmful behaviors can and do cross international boundaries only makes it more difficult to fashion effective responses. more

Another Day, Another Set of Hacking Attacks. News At 11.

While reading Reuters I came across a news article indicating that a number of high profile agencies - from the United Nations to the Canadian Government to government of Taiwan - were broken into over a period of the past five years. ... I'll say it right now, even though I haven't been briefed on it. It was China. more

Monster.com Response to Security Breach Unacceptable

As some of us are continuing to learn this week the Monster.com service has again been successfully hacked. According to a security bulletin posted on Monster.com on January 23rd, 2009, the intruder gained access to the user database, while no resumes were apparently compromised... As a user of Monster.com what I find incredibly upsetting about this situation is that I had to find out about this through a security blog. more

China Betting on IPv6 and First Mover Advantage

The United States' reluctance to invest in IPv6 makes it more likely that China will be in a position to gain the first-mover advantage it seeks. ...Liu Dong, president of the Beijing Internet Institute sums it up succinctly: "We think we can develop the killer applications," he says. China plans to show the rest of the world just how advanced its Internet is at the 2008 Olympics in Beijing. CNGI will control the facilities -- everything from security cameras to the lighting and thermostats -- at the Olympic venues, and events will be broadcast live over the Internet. Even the taxis in Beijing's snarled traffic will connect to CNGI via IPv6 sensors so that dispatchers will be able to direct their drivers away from congestion. more

.COM - The Riskiest Top-Level Domain?

A couple of weeks ago, NetworkWorld published an article indicating that the .com TLD was the riskiest TLD in terms of containing code that can steal passwords or take advantage of browser vulnerabilities to distribute malware... It is unclear to me what they mean by TLD's being risky. The number of domains, 31.3% of .com's being considered risky, what does this actually mean? Is it that 31% of .com's are actually serving up malware or something similar? If so, that seems like a lot because for many of us, nearly 1 in every 3 pages that most people visit would be insecure... more

DNS, Domain Names, and Certificates: The Missing Links in Most Cybersecurity Risk Postures

In 2019, we've seen a surge in domain name system (DNS) hijacking attempts and have relayed warnings from the U.S. Cybersecurity and Infrastructure Agency, U.K.'s Cybersecurity Centre, ICANN, and other notable security experts. Although the topic has gained popularity amongst CIOs and CISOs, most companies are still overlooking important security blind spots when it comes to securing their digital assets outside the enterprise firewalls -- domains, DNS, digital certificates. more

The Purple Team Pentest

It's not particularly clear whether a marketing intern thought he was being clever or a fatigued pentester thought she was being cynical when the term "Purple Team Pentest" was first thrown around like spaghetti at the fridge door, but it appears we're now stuck with the term for better or worse. Just as the definition of penetration testing has broadened to the point that we commonly label a full-scope penetration of a target's systems with the prospect of lateral compromise and social engineering as a Red Team Pentest -- delivered by a "Red Team" entity operating from a sophisticated hacker's playbook. more
