ICANN Security Team Reports on Conficker Post-Discovery Analysis

A paper released today by ICANN provides a chronology of events related to the containment of the Conficker worm. The report, "Conficker Summary and Review," is authored by ICANN's Dave Piscitello, Senior Security Technologist on behalf of the organization's security team. more

GDPR Fine Enough or More Disclosure?

The UK cares about its citizens' privacy to the tune of a $229 million (US) fine of British Airways for a breach that disclosed information of approximately half a million customers. It's exciting -- a significant fine for a significant loss of data. I think GDPR will lead to improved security of information systems as companies scramble to avoid onerous fines and start to demand more from those who provide information security services and products. more

Top Level Domains and a Signed Root

With DNSSEC for the root zone going into production in a couple of weeks, it is now possible for Top Level Domain (TLD) managers to submit their Delegation Signer (DS) information to IANA. But what does this really mean for a TLD? In this post we're going to try to sort that out. more

Trump Names Former Bush Aide Thomas Bossert Chief Adviser on Cybersecurity, Counterterrorism Role

President-elect Donald J. Trump has named Thomas P. Bossert, a top national security aide under President George W. Bush, to be his homeland security adviser, the Trump transition team announced Tuesday morning," Michael D. Shear reporting in the New York Times. more

A Research Finds Banking Apps Leaking Info Through Phones

A recent research seems to indicate that financial industries should increase the security standards they use for their mobile home banking solutions. IOActive Labs recently performed a black box and static analysis of worldwide mobile home banking apps. The research used iPhone/iPad devices to test a total of 40 home banking apps from the top 60 most influential banks in the world. more

Security Shortfalls Exposed in End-to-End Encrypted Cloud Storage Providers

A recent study critically examines the security of popular end-to-end encrypted (E2EE) cloud storage providers, uncovering significant vulnerabilities in platforms widely marketed for their user-controlled privacy features. more

Threat Intelligence Platform in Action: Investigating Important Use Cases

As technology gets more and more sophisticated, tech-savvy cybercriminals are having a field day devising increasingly ingenious ways to steal confidential data from ill-prepared targets. What this means is that an equally sophisticated cybersecurity response is needed to keep attackers at bay. This would involve re-examining reactive cybersecurity practices and adopting a proactive approach towards an active search for risks and vulnerabilities with the help of threat intelligence (TI). more

Newer Cryptographic Advances for the Domain Name System: NSEC5 and Tokenized Queries

In my last post, I looked at what happens when a DNS query renders a "negative" response -- i.e., when a domain name doesn't exist. I then examined two cryptographic approaches to handling negative responses: NSEC and NSEC3. In this post, I will examine a third approach, NSEC5, and a related concept that protects client information, tokenized queries. The concepts I discuss below are topics we've studied in our long-term research program as we evaluate new technologies. more

Exploiting Video Console Chat for Cybecrime or Terrorism

A couple of days ago there was a lot of interest in how terrorists may have been using chat features of popular video console platforms (e.g. PS4, XBox One) to secretly communicate and plan their attacks. Several journalists on tight deadlines reached out to me for insight in to threat. Here are some technical snippets on the topic that may be useful for future reference. more

Lessons From an E-Voting Debacle

There has been a significant focus over the past two years on the vulnerability and cyber threat risks faced for voting systems at the local level. That focus has typically been on State and local jurisdictions like cities, counties and towns, and resulted in the creation of the DHS Elections Infrastructure Information Sharing and Analysis Center (ISAC) to assist. However, there are other local governance entities at significant risk as well. more

Data Broker Reported to Have Exposed a Database Containing Close to 340 Million Individual Records

A data broker based in Palm Coast, Florida, is reported to have exposed a database that contained close to 340 million personal records on a publicly accessible server. more

Botnets: Most Prevalent Threat on the Internet for the Enterprises

Based on the total number of transactions, Zscaler reports botnets as the biggest security risk on the Internet for the enterprises. "Once a host gets infected, the botnet usually spreads quickly within an enterprise. It also generates a significant amount of traffic to the command and control server, to download additional malware or perform other actions." more

SANS Develops Small-Scale City to Train Cyber Warriors

SANS has announced NetWars CyberCity, a small-scale city located close by the New Jersey Turnpike complete with a bank, hospital, water tower, train system, electric power grid, and a coffee shop. NetWars CyberCity was developed to teach cyber warriors from the U.S. Military how online actions can have kinetic effects. more

Decentralizing Cybersecurity Via DNS

Decentralization is a big trend in IT, and everyone has their own definition of what "decentralization" really means. With more organizations fully embracing a work-from-anywhere culture, decentralization has moved past being a fad and turned into a necessity. Decentralized cybersecurity is nothing new. Many of us have been doing it since before the pandemic. more
