Malware Increasingly Uses DNS As Command and Control Channel to Avoid Detection

Number of malware threats that receive instructions from attackers through DNS is expected to increase, and most companies are not currently scanning for such activity on their networks, security experts said at the RSA Conference 2012 on Tuesday. While most malware-generated traffic passing through most channels used for communicating with botnets (such as TCP, IRC, HTTP or Twitter feeds and Facebook walls) can be detected and blocked, it's not the case for DNS (Domain Name System) and attackers are taking advantage of that, said Ed Skoudis, founder of Counter Hack Challenges and SANS fellow. more

Correlation Between Country Governance Regimes & Reputation of Their Internet Address Allocations

We recently analyzed the reputation of a country's Internet (IPv4) addresses by examining the number of blacklisted IPv4 addresses that geolocate to a given country. We compared this indicator with two qualitative measures of each country's governance. We hypothesized that countries with more transparent, democratic governmental institutions would harbor a smaller fraction of misbehaving (blacklisted) hosts. The available data confirms this hypothesis. A similar correlation exists between perceived corruption and fraction of blacklisted IP addresses. more

Cyberspace Solarium Commission Report

The Cyberspace Solarium Report released today is another, in an endless string of reports, that disgorge from Washington committees dealing with the eternal mantra of "defending American interests and values in cyberspace." The challenges (and many reports) here trace back 170 years when transnational telecommunication internets emerged. The dialogue and reports scaled in the 1920s with the emergence of radio internets and cyber threats, then again in the early 1980s... more

It’s Up to Each of Us: Why I WannaCry for Collaboration

WannaCry, or WannaCrypt, is one of the many names of the piece of ransomware that impacted the Internet last week, and will likely continue to make the rounds this week. There are a number of takeaways and lessons to learn from the far-reaching attack that we witnessed. Let me tie those to voluntary cooperation and collaboration which together represent the foundation for the Internet's development. more

Good Samaritans with Network Visibility

In a big open office 30 feet from me, a team of US Veterans speak intently on the phone to businesses large and small, issuing urgent warnings of specific cyber security threats. They call to get stubborn, confused people to take down hidden ransomware distribution sites. They call with bad news that a specific computer at the business has malware that steals login credentials. more

A Brief Primer on Anti-Satellite Warfare Tactics

Satellites make it possible for governments to provide essential services, such as national defense, navigation, and weather forecasting. Private ventures use satellites to offer highly desired services that include video program distribution, telecommunications, and Internet access. The Russian launch of a satellite, with nuclear power and the likely ability to disable satellites, underscores how satellites are quite vulnerable to both natural and manmade ruin. more

Spam Peaked at 200 Billion per Day in 2008, Botnets Nexus of Criminal Activity, Says Cisco

In a 52 page security report released by Cisco, the company has confirmed what has been consistently been observed through out this year: "the Internet-based attacks are becoming increasingly sophisticated and specialized as profit-driven criminals continue to hone their approach to stealing data from businesses, employees and consumers." The 2008 edition of the report has specified the year's top security threats and offers recommendations for protecting networks against attacks that are propagating more rapidly, becoming increasingly difficult to detect, and exploiting technological and human vulnerabilities. more

Did Russian Cyber Attacks Precede Military Action?

The RBNexploit blog states that the website 'president.gov.ge' was under DDoS attack since Thursday. That site is now hosted out of Atlanta, Georgia (don't you love coincidence?) by Tulip Systems who is prominently displaying an AP story... "Speaking via cell phone from Georgia, Doijashvili said the attacks, traced to Moscow and St. Petersburg, are continuing on the U.S. servers." Rusisan military surrogates in the form of the criminal Russian Business Network are engaged in attacks against servers on US soil. This point should be brought up as the Group of 8-1 discusses appropriate responses to Russia's attack on Georgia. more
