Phishing Attack: An Open Letter to the Anti-Spam and Mailbox Operator Community

I'm sure many of you are familiar with the targeted ESP phishing attack that has been ongoing for almost a year now and has led to multiple known ESP system breaches. Return Path was recently a victim of this same attack... In short, a relatively small list of our clients' email addresses was taken from us, meaning those addresses are now the targets of the phishing campaign that are intended to compromise those client systems. more

Outlawing Botnets

The European Commission is apparently considering the promulgation and adoption of a directive that would, at least in part, criminalize botnets. As I understand it, the premise behind adopting such a directive is that since botnets are capable of inflicting "harm" on a large scale, we need to separately criminalize them. I decided to examine the need for and utility of such legislation in this post. more

FISMA Standards Could Have a Major Impact on the Private Sector

The public is taking an increasing interest in ensuring that IT assets of federal agencies are protected from cybersecurity attacks. FISMA is addressing this concern, in part, by initiating a standard setting process for continuous monitoring. The actions taken by NIST for the federal sector could have a very significant impact on the private sector because pending legislation would provide the federal government with the authority to mandate cybesecurity measures on the private sector. more

Mandatory Provision of Abuse Contact Information in WHOIS

An industry professional at Abusix is the backbone behind a proposal to improve and create better mitigation of abuse across different global internet networks. Basically, this introduces a mandatory "abuse contact" field for objects in global Whois databases. This provides a more efficient way for abuse reports to reach the correct network contact. Personally - as a Postmaster for a leading, white-label ISP, I applaud this with great happiness for multiple reasons. I also feel people who handle abuse desks, anti-abuse roles, etc. should closely follow this. more

“Capacity” - The Hidden Word?

What is so secret about the word, "Capacity"? As I read and talk with people I realize the word, "capacity" is typically missing from the DNS discussion. "Capacity" and "Security" are the two cornerstones to maximizing DNS resilience; both of which are typically missing from the DNS discussion. Have you seen a single DNS node easily process over 863,000 queries per second? Have you seen a network routinely handle over 50Gbits/second in outbound traffic alone without breaking a sweat? more

Cyber Crime: It’s All About Data (Part 1)

Cyber crime = crime. How do we make police forces understand this and how to get it prioritized? In this series of blogs I am looking into whether aggregating data can change the way cyber crime is approached and prioritized. At a seminar at the IT Security trade fair in Utrecht detective super intendant Charlie McMurdie, head of the cyber crime unit of the London Metropolitan police, said that cyber crime was recently prioritized by the UK government. She also said the following and I'm allowed to quote this... more

Dan Kaminsky Releases Phreebird for Easy DNSSEC

Today marks another key step in DNSSEC deployment. Congrats to Dan Kaminsky, chief scientist at Doxpara and one of our partners on the Practice Safe DNS campaign, on the release of his new code Phreebird. Announced today at Black Hat Abu Dhabi, Phreebird Suite 1.0 is a free, easy-to-use toolkit that lets organizations "test-drive" DNSSEC deployment. more

.COM - The Riskiest Top-Level Domain? (Part 2)

Following up from my post yesterday, I thought I would take a look at how spammy each particular TLD is. At the moment, I only track 8 TLD's - .cn, .ru, .com, .net, .org, .info, .biz and .name. To check to see which one is the spammiest, I took all of our post-IP blocked mail and determined how many times those messages occurred in email, and how many times that email was marked as spam... more

.COM - The Riskiest Top-Level Domain?

A couple of weeks ago, NetworkWorld published an article indicating that the .com TLD was the riskiest TLD in terms of containing code that can steal passwords or take advantage of browser vulnerabilities to distribute malware... It is unclear to me what they mean by TLD's being risky. The number of domains, 31.3% of .com's being considered risky, what does this actually mean? Is it that 31% of .com's are actually serving up malware or something similar? If so, that seems like a lot because for many of us, nearly 1 in every 3 pages that most people visit would be insecure... more

FISMA Focus: Continuously Monitoring the Cyber-Levee

NIST's release of their initial public draft of SP 800-137, Guide for Continuous Monitoring of Information Systems and Organizations will create a set of challenges for the federal cybersecurity community. Agencies and contractors will need to shape the document through the multi-stage revision process while continuing to implement their own continuous monitoring measures. more
