TLD Domain Abuse: Threat Report - First Half 2011

When it comes to building a robust globe-spanning network of crimeware and making the victims dance to a tune of the cyber-criminals' choosing, you're guaranteed to find domain name abuse at the heart of the operation. DNS provides the critical flexibility and underlying scalability of modern command-and-control (C&C) infrastructure. Cyber-criminals that master DNS (and manage to maintain the stream of new domain registrations that keep it fed) tend to find themselves in command of the largest and most profitable crimeware networks. more

Hiding in Plain Sight: Post-Breach

The majority of network breaches begin and end with the installation of malware upon a vulnerable device. For the rest, once that initial malware beachhead has been achieved, the story is only just beginning. The breach disclosures that make the news are often confusing as they're frequently compiled from third-hand reports, opinions and technical assumptions. More often than not, they include a discussion about the malware - how advanced it was, etc. - and whether any 0-day vulnerabilities were likely used by the mysterious attacker. more

Spam Is on the Decline; What Are the Implications?

Previously, I wrote that the total amount of spam that we are seeing has seen a significant decline over the past year and a half. What does this mean in real terms? Are we finally winning the fight against spam? There are multiple angles. On the one hand, processing spam takes significant system resources... more

Protecting Yourself from Spear Phishing

One of the big trends this year is spear phishing. These are phish attacks that are frequently (though not always) against high profile users. The purpose of these attacks is to steal sensitive data or get elevation of privilege inside the service by exploiting a software vulnerability within the user's computer that transmits usernames and passwords back to the phisher. more

The Design of the Domain Name System, Part I

Over the past 30 years the Domain Name System has become an integral part of the operation of the Internet. Due to its ubiquity and good performance, many new applications over the years have used the DNS to publish information. But as the DNS and its applications have grown farther from its original use in publishing information about Internet hosts, questions have arisen about what applications are appropriate for publication in the DNS, and how one should design an application to work well with the DNS. more

Prediction Methods for Crime

There's a new sheriff in town and he's riding the horse of "predictive policing". Back in July the Santa Cruz Police Department began deploying police officers to places where crime is likely to occur in the future -- making use of new predictive modeling programs that are designed to provide daily forecasts of crime hotspots -- thereby allowing the Department to preempt more serious crimes before they occurred. In essence, this is another physical-world application of machine learning and clustering technologies -- applied to preempting a criminal problem. In the cyber-world we've been applying these techniques for a number of years with great success. more

Anonymous, LulzSec, and the Option of Internet Security

As hacking groups such as Anonymous and LulzSec continue to make headlines, many of us in the Information Security field can only sit back and shake our heads. The large number of successful system breaches, web site defacements, and the publication of confidential data is not at all surprising, and for the most part was only a matter of time. more

DDoS Attacks: Don’t Be In Denial of the Risks

Unlike traditional attacks by hackers which breach a business's security systems, resulting in defaced websites, intellectual property theft and/or customer data theft, a DDoS attack focuses on making a business's Internet connected infrastructure (e.g. web servers, email servers, database servers, FTP servers, APIs, etc.) unavailable to legitimate users. A business's brand reputation, which can take years to establish, can be swept away in just a few hours from a single DDoS attack in the same way a natural disaster like a flood or earthquake can impact a traditional brick and mortar business. more

New Research Reveals 56% Rise in Cost of Cybercrime

New research indicates cyberattacks increasingly plague businesses and government organizations, resulting in significant financial impact, despite widespread awareness. Conducted by the Ponemon Institute, the Second Annual Cost of Cyber Crime Study revealed that the median annualized cost of cybercrime incurred by a benchmark sample of organizations was $5.9 million per year, with a range of $1.5 million to $36.5 million each year per organization. This represents an increase of 56 percent from the median cost reported in the inaugural study published in July 2010. 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

US Department of Transportation Seeking Help for Motor Vehicle Cybersecurity Safeguards

The U.S. Department of Transportation (USDOT), Research and Innovative Technology Administration (RITA) and Volpe National Transportation Systems Center (Volpe Center), today released a Request for Information (RFI) seeking to obtain informed views on the "perceived needs, prevailing practices, and lessons learned concerning the cybersecurity and safety of safety-critical electronic control systems used in various modes of transportation and other industry sectors."

DNSSEC Baby Steps Reported at ICANN 41

The Internet is slowly beginning to adopt the new DNSSEC domain names standard, but significant challenges remain. That was the main takeaway from a four-hour workshop on the technology held during the recent ICANN 41 public meeting in Singapore, which heard from many domain registries, registrars and other infrastructure providers. more

Automated Web Application Attacks Can Peak at 25,000 an Hour

Web applications, on average, experience twenty seven attacks per hour, or roughly one attack every two minutes, according to the newly released Imperva Web Application Attack Report. Report also notes that when websites came under automated attack they received up to 25,000 attacks in one hour, or 7 attacks every second. more

DNSSEC Maintenance - Just Like Mowing the Lawn

DNSSEC is a hot topic. It's a technology newly unleashed on popular networking, which has led to countless articles and posts on the subject, including right here on CircleID. The way a lot of articles try to get your attention is to talk about a technology, like DNSSEC, in a way that makes the technology either seem really significant or really complicated. That is why a lot of articles about DNSSEC make it sound like something huge, complicated, and scary. But it's not. more
