Emerging Cyber-Security Threats and Implications for the Private Sector

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... However, the successful introduction of new gTLDs will also create new challenges of security for the private sector. more

Policy Failure Enables Mass Malware: Part II (ICANN and OnlineNIC)

On Wednesday September 29th at 1PM there will be a meeting in the Old Executive Building in Washington D.C. with Registries and domain Registrars to discuss illegal Internet sales of prescription drugs. ICANN was originally invited but declined because citing "inappropriateness" . One "U.S." Registrar who definitely will not be in attendance is OnlineNIC more

UK’s Government Websites Infected by Cryptocurrency Mining Malware

Thousands of websites are reported to have been infected by malware over the weekend forcing visitors' computers to mine cryptocurrency while using the sites. more

Report on DNS Amplification Attacks

In this newly released paper Randal Vaughn and Gadi Evron discuss the threat of Distributed Denial of Service (DDoS) attacks using recursive DNS name servers open to the world. The study is based on case studies of several attacked ISPs reported to have on a volume of 2.8Gbps. One reported event indicated attacks reaching as high as 10Gbps and used as many as 140,000 exploited name servers. more

The Darkening Web: Is there Light at the end of the Tunnel?

In his book "The Darkening Web: The War for Cyberspace" (Penguin Books, New York 2017), Alexander Klimburg, an Austrian-American academic, gives "Internet Dreamers" a "Wake Up Call". He tells us the background-story why people start to be "anxious about the future of the Internet", as the recent ISOC Global Internet Report "Paths to Our Digital Future" has recognized. Klimburg refers to Alphabets CEO Erich Schmidt, who once said that "the Internet is the first thing that humanity has built that humanity does not understand". more

Protecting the Internet: Certified Attachments and Reverse Firewalls?

In many respects the internet is going to hell in a hand basket. Spam, phishing, DNS poisoning, DDoS attacks, viruses, worms, and the like make the net a sick place. It is bad enough that bad folks are doing this. But it is worse that just about every user computer on the net offers a nice fertile place for such ill behavior to be secretly planted and operated as a zombie under the control of a distant and unknown zombie farmer. ...Some of us are coming to the converse point of view that the net is being endangered by the masses of ill-protected machines operated by users. more

Patching is Hard

There are many news reports of a ransomware worm. Much of the National Health Service in the UK has been hit; so has FedEx. The patch for the flaw exploited by this malware has been out for a while, but many companies haven't installed it. Naturally, this has prompted a lot of victim-blaming: they should have patched their systems. Yes, they should have, but many didn't. Why not? Because patching is very hard and very risk, and the more complex your systems are, the harder and riskier it is. more

Understanding the Threat Landscape: Indicators of Compromise (IOCs)

I previously provided a brief overview of how Verisign iDefense characterizes threat actors and their motivations through adversarial analysis. Not only do security professionals need to be aware of the kinds of actors they are up against, but they should also be aware of the tactical data fundamentals associated with cyber-attacks most commonly referred to as indicators of compromise (IOCs). Understanding the different types of tactical IOCs can allow for quick detection of a breach... more

1 Terabit DDoS Attacks Become a Reality; Reflecting on Five Years of Reflections

Reflection amplification is a technique that allows cyber attackers to both magnify the amount of malicious traffic they can generate, and obfuscate the sources of that attack traffic. For the past five years, this combination has been irresistible to attackers, and for good reason. This simple capability, of turning small requests into larger, 'amplified' responses, changed the Distributed Denial of Service (DDoS) attack landscape dramatically. more

Verisign’s Perspective on Recent Root Server Attacks

On Nov. 30 and Dec. 1, 2015, some of the Internet's Domain Name System (DNS) root name servers received large amounts of anomalous traffic. Last week the root server operators published a report on the incident. In the interest of further transparency, I'd like to take this opportunity to share Verisign's perspective, including how we identify, handle and react, as necessary, to events such as this. more

Cybersquatting & Banking: How Financial Services Industry Can Protect Itself Online (Webinar)

Businesses in the financial services sector are among the most frequent targets of cybersquatters. In this free webinar, I will be joining Craig Schwartz of fTLD Registry Services to provide important information about how domain name fraud is affecting the financial services industries, including banking and insurance, and what businesses and consumers can do to protect themselves online. more

The ENISA Botnet Report: Thoughts on the State of Play in Smart Phones

At the ENISA presentation on her botnet report at eco in Cologne, 9 and 10 March, one of the slots was dedicated to threats to the mobile environment. The message I was supposed to come home with was: we can still count the numbers of mobile viruses manually, <600; the problem will never be the same as on a fixed network as traffic is monitored and metered: We detect it straight away. We are studying the problem seriously. Are mobile operators really prepared for what is coming? more

Microsoft’s Size Means Malicious Cyber Actors Thrive

Last month, the Russian state-sponsored hacking group "Midnight Blizzard" gained access to the email accounts of Microsoft leadership, even exfiltrating documents and messages. The group reportedly used a simple brute-force style attack to access a forgotten test account and then exploited the permissions on that account to access the emails of employees in the cybersecurity and legal teams. more

Close to Half of US East Coast Fuel Supply Shutdown Due to Ransomware Cyberattack

Colonial Pipeline, which accounts for close to half of the United States East Coast's fuel, has shut down its operations due to a cyberattack. The incident, believed to be the largest successful cyberattack on oil infrastructure in the U.S., was disclosed over the weekend. more

Preliminary Thoughts on the Equifax Hack

As you've undoubtedly heard, the Equifax credit reporting agency was hit by a major attack, exposing the personal data of 143 million Americans and many more people in other countries. There's been a lot of discussion of liability; as of a few days ago, at least 25 lawsuits had been filed, with the state of Massachusetts preparing its own suit. It's certainly too soon to draw any firm conclusions... but there are a number of interesting things we can glean from Equifax's latest statement. more
