Kelihos Is Dead: Long Live Kelihos

The King is dead. Long live the King! Or, given this week's events, should the phrase now be "Kelihos is dead. Long live Kelihos"? It is with a little amusement and a lot of cynicism that I've been watching the kerfuffle relating to the latest attempt to take down the Kelihos botnet. You may remember that a similar event ("Kelihos is dead") occurred late last year after Microsoft and Kaspersky took it on themselves to shut down the botnet known as Kelihos (or sometimes as Waledac 2.0 or Hlux). more

An Investigation Shows How Bomb Threat Scammers Hijacked Thousands of Big-Name Domains

Ars Technica's Dan Goodin reports that an "investigation shows the spam run worked by abusing a weakness at GoDaddy that allowed the scammers to hijack at least 78 domains belonging to Expedia, Mozilla, Yelp, and other legitimate people or organizations." more

China: Is It Our Cyber Defense Red Herring?

There are thousands of articles perpetuating the claim that China is out to get us on the Internet. And yet, all these discussions are begging the question, is it China attacking? Also, are they even the "usual suspects"?
While I can point to real facts of China making active use of information warfare, cyber warfare, or whatever else you choose to call it (such as the release of 0 days being patched by Microsoft and originally reported by the Taiwanese government, search Microsoft's site), I can also point to Germany (intelligence Trojan horse), the US (The Farewell Dossier) and other countries such as North Korea (without much detail, so questioned)... more

DNSSEC Root Signature, Almost There!

IT security specialists have known for years that the plain DNS is not to be trusted. Any hope for improvement rests on the DNSSEC protocol deployment. In this post, I will review the current status in one critical aspect, namely the DNS root signature key management. The other two foremost are the application usage of DNSSEC protocol functionality and the operational front, or the extent of deployment in the DNS infrastructure. The operational front includes the support by the DNS root nameservers, but my focus on signature key management leaves this issue aside. more

BP and Incident Response: How Well Do Oil and Security Mix?

BP and the Oil Industry are taking a lot of heat these days - much of it rightly so. Moving beyond the drama and evaluating the overall response of BP and others reinforces much of what is taught in incident response training and preparation... by showing the outcomes when one does not respond well. This is probably the most important incident that the responders involved will deal with in their professional lives. For those of us working to protect Internet Infrastructure and resources there are useful lessons as we consider what is happening in the Gulf of Mexico and their response effort. more

Website Seals of Approval: Can You Trust Them?

The abuse of well-known seal of approvals seems to be the latest ruse used by online fraudsters. Leveraging reputable names that existed long before anyone heard of the Internet is a blaring reminder that even trustworthy seals are not off limits to scammers. In fact, linking to reliable sources of reviews and certification is proving to be an essential part of any fraud strategy today. more

How Domain Data Helps Thwart BEC Fraud

It's true, domain data has many practical uses that individuals and organizations may or may not know about. But most would likely be interested in how it can help combat cyber threats, which have been identified as the greatest risks businesses will face this year. Dubbed as the greatest bane of most organizations today, cybersecurity can actually be enhanced with the help of domain data. How? more

Microsoft and Financial Services Groups Disrupt Zeus Botnet Servers

"With this legal and technical action, a number of the most harmful botnets using the Zeus family of malware worldwide have been disrupted in an unprecedented, proactive cross-industry operation against this cybercriminal organization." more

What COVID-19 Means for Network Security

The COVID-19 Pandemic is causing huge social and financial shifts, but so far, its impact on network security has gone under-reported. Yet with thousands of companies worldwide requiring millions of employees to work remotely, network administrators are seeing unprecedented changes in the ways that clients are using their networks and new threats that seek to leverage the current crisis. more

DDoS Attacks Getting More Powerful, ISPs Report Concern Over New Threats and Budget Pressures

Massive distributed denial of service (DDoS) attacks against ISPs and their customers have almost doubled over the past year, according to a new security report. Attacks on networks making them unavailable to intended users -- also known as distributed denial of service (DDoS) attacks -- exceeded 40 gigabits in the last year according to Arbor Networks' annual survey of ISPs from North America, South America, Europe and Asia. more

Experts Propose Plan for More Secure Wi-Fi Devices

Over 260 global network and security experts have collectively responded to the newly proposed FCC rules laid out in ET Docket No. 15-170 for RF Devices such as Wi-Fi routers by proposing a new approach to improve the security of these devices. The letter warns FCC ruling will cause more harm than good and risk a significant overreach of the Commission's authority. more

The Uses and Abuses of Cryptography

Another day, another data breach, and another round of calls for companies to encrypt their databases. Cryptography is a powerful tool, but in cases like this one it's not going to help. If your OS is secure, you don't need the crypto; if it's not, the crypto won't protect your data. In a case like the Anthem breach, the really sensitive databases are always in use. more

Securing the Routing System at NANOG 74

The level of interest in the general topic of routing security seems to come in waves in our community. At times it seems like the interest from network operators, researchers, security folk and vendors climbs to an intense level, while at other times the topic appears to be moribund. If the attention on this topic at NANOG 74 is anything to go by we seem to be experiencing a local peak. more

KSK Rollover, Elliptical Curve Vulnerabilities, Surveillance and Privacy. Are We Building Trust?

ICANN just recently performed a Root Zone DNS Security Extensions (DNSSEC) Key Signing Key (KSK) Rollover. The recent KSK Rollover that took place on the 11th October 2018. The KSK Rollover has been successful and congratulations are in order. The Root Zone DNSSEC Key Signing Key "KSK" is the top most cryptographic key in the DNSSEC hierarchy. The KSK is a cryptographic public-private key pair. more

Patient Care Suffers When Data Security is a Budgetary Concern

According to a recent Homeland Security News Wire article, nearly 8 million patient medical records were compromised over the course of the previous two years due to data security breaches. As more hospitals and patient care providers move to store patient data electronically -- primarily as a cost savings effort -- the risk and exposure of our private medical information increases while our individual control over this information diminishes. more
