Cyberattack

Exploits, Curdled Milk and Nukes (Oh my!)

Throughout the second half of 2012 many security folks have been asking "how much is a zero-day vulnerability worth?" and it's often been hard to believe the numbers that have been (and continue to be) thrown around. For the sake of clarity though, I do believe that it's the wrong question... the correct question should be "how much do people pay for working exploits against zero-day vulnerabilities?" more

WCIT’s Security Issues

Another contentious issue at the WCIT in Dubai is 'security'. There has been a dramatic increase in nervousness regarding a whole range of security issues, especially in relation to the internet. They include: SPAM, denial-of-service-attacks, identity theft, cybercrime, cyberwarfare, and privacy issues on social media. From the list above it is clear that some of these issues are related to content, while some can be classified as national security and others as criminal offences. In other words, there is no clear-cut issue on what constitutes security. more

Raspberries! Botnet Spam Just Got a Whole Lot More Dangerous

Many have heard of botnets, but for those that aren't certain what they are: Botnets are armies of hacked zombie computers that have malware on them, and send spam email at the command of operators anywhere in the world. They can also be told to deploy denial of service attacks, by all hitting the homepage of a given company, or attacking the DNS server or a service or country. more

The Recent DDoS Attacks on Banks: 7 Key Lessons

Starting in mid-September, one of the largest and most sophisticated DDoS attacks ever targeted the titans of American banking. Initially, victims included Bank of America, JPMorgan Chase, Wells Fargo, PNC Bank, and U.S. Bancorp. In the weeks to come, others would also feel the pain. Websites crashed, customers were unable to make transactions and IT professionals and PR gurus went into panic mode. Leon Panetta, U.S. Secretary of Defense, said the attacks foreshadowed a "Cyber Pearl Harbor." more

Persistent Threat Detection on a Budget

If there's one simple - high impact - thing you could do to quickly check whether your network has been taken over by a criminal entity, or uncover whether some nefarious character is rummaging through your organizations most sensitive intellectual property out of business hours, what would it be? In a nutshell, I'd look to my DNS logs. It's staggering to me how few security teams have gotten wise to regularly interrogating the logs from their recursive DNS servers. more

Is The Term “Cyberwarfare” Overstating the Case?

At the Virus Bulletin conference last month, Andrew Lee from ESET gave a talk entitled "Cyberwar: Reality or Weapon of Mass Distraction?" In it, Lee talks about how the term "cyberwar" is thrown around a lot these days. However, he disagreed with the use of the term because it uses inflationary language and overstates the case; today's "cyberwar" is not the same as a conventional ware. more

State Hacking: Do’s and Don’ts, Pros and Cons

Over the past days a lot has been said and written on counter hacking by enforcement agencies. The cause is a letter Dutch Minister I. Opstelten, Security & Justice, sent to parliament. Pros and cons were debated and exchanged. Despite the fact that I perfectly understand the frustration of enforcement agencies of having to find actionable data and evidence that gets criminals convicted in a borderless, amorphous environment, a line seems to be crossed with this idea presented to Dutch parliament. Where are we? more

The new gTLD program will have a profound impact on the private sector's increasing dominance over Internet information resources and ownership of critical registry technical infrastructure assets. It is already anticipated that only the private sector will take full advantage of the commercial possibilities...

The Internet and the Legitimacy of Governments

In two recent debate events I participated in, on iFreedom and privacy in the online world, mistrust of government and government's intentions and motivations on and towards the Internet were abundantly present with more than just a few people in the audiences. The emotions were not new to me, no, it was the rationality that surprised and sometimes almost shocked me. Why? Well, should these sentiments get the support of the majority of people, it would undermine all legitimacy of a government to govern. Let's try and take a closer look. more
