It’s Time to Rethink Outage Reports

Much has been said about the criticality of the small coterie of large-scale content distribution platforms and their critical role in today's Internet. These days when one of the small set of core content platforms experiences a service outage, then it's mainstream news, as we saw in June of this year with outages reported in both Fastly and Akamai. In the case of Akamai, the June outage impacted three of Australia's largest banks, their national postal service, the country's reserve bank, and one airline... more

The Importance of Understanding Attacker Target Selection

There's a bit of a debate going on about whether the Kaseya attack exploited a 0-day vulnerability. While that's an interesting question when discussing, say, patch management strategies, I think it's less important to understand attackers' thinking than understand their target selection. In a nutshell, the attackers have outmaneuvered defenders for almost 30 years when it comes to target selection. more

New Research Indicates Nearly 80% of Top US Energy Companies Are at Serious Risk for Cyberattacks

In light of the Biden administration's recent efforts in protecting critical infrastructure from cyber threats, new research from CSC indicates that a majority of the top energy companies in the U.S. are vulnerable to attack due to shortcomings in their online operations.

We cannot go backward; the only way forward is to ensure that this new digital environment is made as safe as possible from a personal, social, political and economic perspective. We are currently struggling on these fronts. Unfortunately, we have now clearly entered a situation of cyber warfare. States now use digital technologies to impose and undermine ideologies. more

What Are the Connections to Identified Hafnium Malicious IP Addresses?

Cyber attackers are very skilled at infiltration. They'd find ways into a house through cracks and holes that the homeowner doesn't know about. Analogically speaking, that's what the new cyber attack group dubbed "Hafnium" did when they identified several zero-day Microsoft Exchange vulnerabilities to get into target networks. With thousands of users for every Microsoft Exchange server, the attack has far-reaching implications. First, it establishes the presence of a new threat actor group in town. What else could they be up to? more

78% of Cybersecurity Professionals Expect an Increase in DNS Threats, Yet Have Reservations

A recent survey conducted by the Neustar International Security Council confirmed the heightened interests on domain name system (DNS) security. The survey reveals that over three-quarters of cybersecurity professionals anticipate increases in DNS attacks, especially with more people shopping online amid the pandemic. Yet, close to 30% have reservations about their ability to respond to these attacks. more

Notes from NANOG 81

As the pandemic continues, the network operator community continues to meet online. NANOG held its 81st meeting on February 8 and 9, and these are my notes from some of the presentations at that meeting... Ethernet, developed in 1973 at Xerox PARC, was a revolutionary step in network architectures in many ways. The common bus architecture imposed several constraints on the network that have echoed through the ensuing four decades in all kinds of ways. more

3 Most Scary Attacks that Leaked Personally Identifiable Information (PII) of Millions of Users

Cybercriminals are increasingly targeting Personally Identifiable Information (PII). The reason being "data is the new gold" in this digital world, and the more sensitive some data is, the more value it has. There is no more sensitive data than personally identifiable information because it contains enough information to identify you digitally. Examples of personally identifiable information include name, email, contact number, address, social security number, tax file number, banking or financial information, and more such data that helps identify you. more
