VoIP Security Predictions for 2009

Here are my VoIP and Voice security predictions for 2009, limited to just a few, key predictions... The poor economy will slow the adoption rate for VoIP and Unified Communications (UC). This will continue to limit the size of the enterprise VoIP deployments for potential hackers to exploit. VoIP/UC will continue to be mostly an internal/campus application where the threat level for attack is low, so deployments will be largely secured along the same lines as other data network applications. more

Global Technical Internet Related Issues That Need Fixing

Given its engineering background, many positive contributions can be made by the engineering community in the broader ICT world to assist in addressing some of the broader internet issues, often addressed within the more limited telecoms environment.. Of course some of this is already happening; however much more work would be needed to strengthen the technical foundations of the internet. Just as an example, the type of issues that could be addressed by a broader ICT engineering foundation could include... more

Global DNS SSR Recap

This past February, around 100 DNS industry experts met in Atlanta, GA for the "The Global DNS Security, Stability, & Resiliency Symposium." Organized by ICANN and hosted by Georgia Tech, this event was to strengthen personal relationships between operators and review what we know about the DNS infrastructure... The content included three breakout groups over two days: Enterprise Use of DNS, DNS in Resource Constrained Environments, and Combating Malicious Use of DNS... more

Video: IETF Chair Jari Arkko on “Pervasive Monitoring and the Internet”

Today at the RIPE 67 event in Athens, Greece, IETF Chair Jari Arkko gave a presentation on "Pervasive Monitoring and the Internet" where he spoke about the ongoing surveillance issues and: What do we know? What are the implications? What can we do? Similar to his earlier article on the topic, Jari looked at the overall issues and spoke about how Internet technology should better support security and privacy. more

Four Steps to an Effective Brand Protection Program

Internet use has become ever more pervasive. With around five billion global users, it generates an economy of around 15% of global gross domestic product (GDP); that's around $15 trillion and is a figure that's growing 2.5 times faster than GDP itself. This makes the internet an attractive channel for infringers. Phishing and other fraud tactics, selling counterfeit goods online, and digital piracy are primary areas of concern. more

Exploiting the Firewall Beachhead: A History of Backdoors Into Critical Infrastructure

There is no network security technology more ubiquitous than the firewall. With nearly three decades of deployment history and a growing myriad of corporate and industrial compliance policies mandating its use, no matter how irrelevant you may think a firewall is in preventing today's spectrum of cyber threats, any breached corporation found without the technology can expect to be hung, drawn, and quartered by both shareholders and industry experts alike. more

Remediating U.S. 5G Global Supply Chain Security Engagement

For nearly the past four years, the Trump Administration has purported to treat 5G supply chain security through empty political gestures such as network equipment banning. The disinformation reached its absurd zenith subsequent to the election with the Q-Anon myth of the Kraken. (The Myth advanced by Trump attorneys asserted the long-deceased Hugo Chavez working with China was corrupting voting machine software to deprive Trump of another term.) more

More on ‘Researchers Hijack Storm Worm to Track Profits’

Always good for information on the spam economy, Brian Krebs of the Washington Post has just published a truly fascinating article: Researchers Hijack Storm Worm to Track Profits. Bottom line: a one-in-twelve-million conversion rate of spam to sales seems to be enough to keep the spam economy going. The article covers a project by researchers at UC San Diego and UC Berkeley, who managed to infiltrate the Storm Worm bot network and take over a small portion of it. more

Chinese APT Groups Exploit Global Domains in Sweeping Cyber Campaign

A years-long cyberespionage campaign by a Chinese state-sponsored group known as Salt Typhoon has revealed a striking escalation in both scale and technical sophistication. more

DDoS Attack Size Breaks 100 Gbps for First Time, Up 1000% Since 2005

"2010 should be viewed as the year distributed denial of service (DDoS) attacks became mainstream as many high profile attacks were launched against popular Internet services and other well known targets," reports Arbor Networks in its just released Sixth Annual Worldwide Infrastructure Security Report. According to the report, the year also witnessed a sharp escalation in the scale and frequency of DDoS attack activity on the Internet. The 100 Gbps attack barrier was reached for the first time while application layer attacks hit an all-time high. Service providers experienced a marked impact on operational expense, revenue loss and customer churn as a result. more

US Department of Homeland Security Issues Emergency Directive Ordering Agencies to Audit DNS Records

The U.S. Department of Homeland Security has issued a rare "emergency" directive ordering federal agencies to audit all DNS records within ten days. more

Tackling Cyber Security: Should We Trust the Libertarians?

One of the RSS feeds that I read is Reason magazine, which is a web site for libertarians. In general, libertarians want less government intervention both in our personal lives and in the economy. The idea behind libertarians is that today's Republicans want less government intervention in our economy but are perfectly fine to have them dictate some aspects of morality. Similarly, today's Democrats want less government intervention in our personal lives but are perfectly fine with creating government bureaucracy to deliver social services. That's an oversimplified summary, but is more or less correct. About two months ago I got an article in my RSS feed where Reason was commenting on the government's response to the cyber war threats. more

Average Daily Malware at All Time High, Spam Lowest Since 2008

McAfee, Inc. today unveiled its McAfee Threats Report: Third Quarter 2010, which uncovered that average daily malware growth has reached its highest levels, with an average of 60,000 new pieces of malware identified per day, almost quadrupling since 2007. At the same time, spam levels decreased in volume this quarter, both globally and in local geographies. Spam hit a two year low this quarter while malware continued to soar. More than 14 million unique pieces of malware were identified in 2010, one million more than Q3 2009. more

British Security Researcher Credited for Stopping WannaCry Is Charged in a U.S. Cybercrime Case

The 23-year-old British security researcher, Marcus Hutchins, who a few months ago was credited with stopping the WannaCry outbreak by discovering a hidden "kill switch" for the malware, is now reported to have been arrested by the FBI over his alleged involvement in separate malicious software targeting bank accounts. more

A Secure Recursive Caching DNS Server

Over the last couple of weeks I have spent some time working on a project to develop a DNS cache for Windows that is intended to be reasonably secure against spoof attacks, in particular in situations where NAT firewalls may prevent port randomization. The program is evolving, but currently uses a couple of ideas to attempt to defeat spoof attacks... The source code is intended to be entirely un-encumbered, that is free in all respects. I would welcome any suggestions or comments on the aims of the project, the source code, the functionality of the program or other ideas. more
