Extreme Vulnerability at the Edge of the Internet - A Fresh New Universal Human-Rights Problem

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

How Frequently Do Botnets Reuse IP Addresses?

I wonder how much botnets reuse IP addresses. Do they infect a system and spam, get blocked, discard the IP and move onto the next (new) one? This means that they have a nearly unlimited supply of IP addresses. Or do they infect a system and spam, get blocked, and then let it go dormant only to awaken it some time later? I decided to take a look. more

The Sportsmanship of Cyber-warfare

As a bit of a history buff I can't avoid a slight tingling of déjà vu every time I read some new story commenting upon the ethics, morality and legality of cyber-warfare/cyber-espionage/cyberwar/cyber-attack/cyber-whatever. All this rhetoric about Stuxnet, Flame, and other nation-state cyber-attack tools, combined with the parade of newly acknowledged cyber-warfare capabilities and units within the armed services of countries around the globe, brings to the fore so many parallels... Call me a cynic if you will, but when the parallels in history are so evident, we'd be crazy to ignore them. more

The Challenge of DNS Security

When the domain name system (DNS) was first designed, security was an afterthought. Threats simply weren't a consideration at a time when merely carrying out a function - routing Internet users to websites - was the core objective. As the weaknesses of the protocol became evident, engineers began to apply a patchwork of fixes. After several decades, it is now apparent that this reactive approach to DNS security has caused some unintended consequences and challenges. more

Spamhaus Tells Us That Botnets Are Getting Worse

The Spamhaus Project just published a long article about the botnets they've been watching during 2014. As this chart shows, we're not making any progress. They also note that the goals of botnets have changed. While in the past they were mostly used to send spam, now they're stealing banking and financial information, engaging in click fraud, and used for DDoS and other malicious mischief. more

Debilitating Cyber Attack: Not If, But When?

We all know how easy it can be to ignore or underestimate the possibly, or even likelihood, of a terrorist attack; just remember what happened on 9-11. That seems to be just what the U.S. is doing when it comes to a possible Cyber-Attack, no not in other countries, but right here at home where targets like private sector companies, who provide vital economic and emergency services to our population using broadband infrastructure, and are woefully under-secured for such attacks. more

ESP Compromises and Their Lack of Security

Over at Word to the Wise, Laura Atkins has a post up where she talks about the real problem with ESPs and their lack of internal security procedures which resulted in the breach of many thousands of email addresses (especially Epsilon). However, Atkins isn't only criticizing ESP's lack of security but also the industry's response wherein they have suggested countermeasures that are irrelevant to the problem.  more

Digital Geneva Convention: Multilateral Treaty, Multistakeholder Implementation

Microsoft's call for a Digital Geneva Convention, outlined in Smith's blog post, has attracted the attention of the digital policy community. Only two years ago, it would have been unthinkable for an Internet company to invite governments to adopt a digital convention. Microsoft has crossed this Rubicon in global digital politics by proposing a Digital Geneva Convention which should 'commit governments to avoiding cyber-attacks that target the private sector or critical infrastructure or the use of hacking to steal intellectual property'. more

Hiding in the Firmware?

The most interesting feature of the newly-described "Equation Group" attacks has been the ability to hide malware in disk drive firmware. The threat is ghastly: you can wipe the disk and reinstall the operating system, but the modified firmware in the disk controller can reinstall nasties. A common response has been to suggest that firmware shouldn't be modifiable, unless a physical switch is activated. more

X-Force Report: Corporations Becoming No. 1 Security Threat to Their Own Customers

With the alarming increase in cyberattacks, criminals are literally turning businesses against their own customers in order to steal consumer's personal data, warns the latest annual X-Force Trend and Risk report from IBM. "The security industry puts a lot of effort into the technical evaluation of security threats, examining, sometimes at great length, the potential threat that each issue might present to corporations and consumers. Criminal attackers out for profit, however, have considerations that the security industry does not always take into account, such as monetization cost and overall profitability." more

Widespread Compromised Routers Discovered With Altered DNS Configurations

A widespread compromise of consumer-grade small office/home office (SOHO) routers has been discovered by threat intelligence group Team Cymru. According to the report, "attackers are altering the DNS configuration on these devices in order to redirect victims DNS requests and subsequently replace the intended answers with IP addresses and domains controlled by the attackers, effectively conducting a Man-in-the-Middle attack." more

What Chinese DDoS Malware Looks Like

While at that same Virus Bulletin conference that I was talking about earlier in my other post, I also had the chance to check out a session on Chinese DDoS malware put on by some folks from Arbor Networks. As little insight as I have into Android malware, I know even less about Chinese DDoS malware. So what's Chinese DDoS malware like? What are its characteristics? more

Cyber Security and the White House, Part 2 - Cyberwarfare

This is a follow-up to my previous post on Cybersecurity and the White House. It illustrates an actual cyberwarfare attack against Estonia in 2007 and how it can be a legitimate national security issue. Estonia is one of the most wired countries in eastern Europe. In spite of its status of being a former Soviet republic, it relies on the internet for a substantial portion of everyday life -- communications, financial transactions, news, shopping and restaurant reservations all use the Internet. Indeed, in 2000, the Estonian government declared Internet access a basic human right... more

Six Approaches to Creating an Enterprise Cyber Intelligence Program

As few as seven years ago, cyber-threat intelligence was the purview of a small handful of practitioners, limited mostly to only the best-resourced organizations - primarily financial institutions that faced large financial losses due to cyber crime - and defense and intelligence agencies involved in computer network operations. Fast forward to today, and just about every business, large and small, is dependent on the Internet in some way for day-to-day operations, making cyber intelligence a critical component of a successful business plan. more

Understanding and Detecting Mobile Malware Threats

Every couple of years there's a new "hot threat" in security for which vendors abruptly tout newfangled protection and potential customers clamor for additional defense options. Once upon a time it was spyware, a few years ago it was data leakage, and today it's mobile malware. It's a reoccurring cycle, analogous to the "blue is the new black" in fashion -- if you fancy adopting a certain cynical tone. more
