Email and Social Media Accounts Under the Spotlight in UK’s Proposed New ‘Spy’ Plan

It would be reasonable to assume that your employer is archiving your email communications. But what about your personal emails, texts, phone calls and Facebook posts. Are these really private? Not for long, if the UK government has its way. It has been reported that its new anti-terror plan, if passed, would require Internet providers and phone companies to store all online communications by UK citizens for one year. more

Debilitating Cyber Attack: Not If, But When?

We all know how easy it can be to ignore or underestimate the possibly, or even likelihood, of a terrorist attack; just remember what happened on 9-11. That seems to be just what the U.S. is doing when it comes to a possible Cyber-Attack, no not in other countries, but right here at home where targets like private sector companies, who provide vital economic and emergency services to our population using broadband infrastructure, and are woefully under-secured for such attacks. more

How Frequently Do Botnets Reuse IP Addresses?

I wonder how much botnets reuse IP addresses. Do they infect a system and spam, get blocked, discard the IP and move onto the next (new) one? This means that they have a nearly unlimited supply of IP addresses. Or do they infect a system and spam, get blocked, and then let it go dormant only to awaken it some time later? I decided to take a look. more

World Notices That Verisign Said Three Months Ago That They Had a Security Breach Two Years Ago

The trade press is abuzz today with reports about a security breach at Verisign. While a security breach at the company that runs .COM, .NET, and does the mechanical parts of managing the DNS root is interesting, this shouldn't be news, at least, not now. Since Verisign is a public company, they file a financial report called a 10-Q with the SEC every quarter. According to the SEC's web site, Verisign filed their 10-Q for June through September 2011 on October 28th. more

Greylisting Still Works - Part II

In my last post I blogged about greylisting, a well-known anti-spam technique for rejecting spam sent by botnets. When a mail server receives a an attempt to deliver mail from an IP address that's never sent mail before, it rejects the message with a "soft fail" error which tells the sender to try again later. Real mail senders always retry, badly written spamware often doesn't. I found that even though everyone knows about greylisting, about 2/3 of IPs don't successfully retry. more

White House Issues Cloud Computing Policy Standards

U.S. Office of Management and Budget released a memo today establishing a program to reduce "duplicative efforts, inconsistencies and cost inefficiencies when assessing and authorizing cloud systems." The initiative called, Federal Risk and Authorization Management Program (FedRAMP), is aimed to develop a standardized approach to security assessment, authorization, and continuous monitoring for cloud products and services through standardized security requirements and controls. more

When Cyber Awareness Is Fundamentally Lacking

"Smartphones (and tablets, WdN) are invading the battlefield", reports the Economist on its website of 8 October 2011. On the same day the hacking of U.S. drones is reported on by several news sites. ("They appear friendly". Keyloggers???) Is this a coincidence? more

Government and Botnets

The US government is looking at telling ISPs how to deal with compromised customers and botnets. They're a bit late to the party, though. Most of the major commercial ISPs have been implementing significant botnet controls for many years now. more

Foreign Hackers Attack Canadian Government

An unprecedented cyberattack on the Canadian government also targeted Defence Research and Development Canada, making it the third key department compromised by hackers, CBC News has learned. ... While there is no definitive proof, of course, that China was behind these attacks, there is a lot of circumstantial evidence that points in that direction. China (allegedly) has a long history of engaging in espionage activities in order to gain access to information. In the United States, this is sometimes referred to as cyber warfare, but I think that cyber espionage is a better choice of terms. 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

United States Is the Most Bot-Infected Country. Right?

A couple of days ago, Threatpost posted an article indicating that the United States is the most bot-infected country... I think that Microsoft's mechanism of measuring bot infections is a good one, not necessarily because it is the most accurate but because it represents the most complete snapshot of botnet statistics. Because Microsoft Windows is installed on so many computers worldwide and because so many users across the world call home to the MSRT, Microsoft is able to collect a very large snapshot of data. more

Russian Cybercrime is Organized / Russian Cybercrime is Not Organized

The more I read, the more I see conflicting views on the state of the criminal cybercrime world. On the one hand, the Russian criminal cybercrime underworld is a scary, organized place... On the other hand, there is the position that that position is an exaggeration of what it is actually like and that it's a bunch of ragtag folks who have some advanced computer skills but they are not formally organized. ... I see this very similarly to how I see cyber warfare... more

US Facing a Human Capital Crisis in Cybersecurity, Says CSIS

A new study has been released by Center for Strategic and International Studies (CSIS) Commission on Cybersecurity for the 44th President that looks into cybersecurity manpower challenges in the United States. The report titled, "A Human Capital Crisis in Cybersecurity," is produced by CSIS - a bipartisan public and foreign policy think tank in Washington. more

Who is Blocking WHOIS?

On April 16 ICANN issued a breach notice to Turkish Registrar Alantron for not consistently providing access to its WHOIS database via Port 43, a command-line query location that all Registrars are required to supply under conditions of their contract with ICANN under section 3.3.1. Four days later they issued a breach to Internet Group do Brazil for the same problem. ... The WHOIS record, as we all know, is a massive fraud with illicit parties filling records with bogus information and hiding behind anonymity. more

Deploying DNSSEC: Lessons from Domain Registrar Implementation

As a registrar at the front end of the DNSSEC deployment effort, our technical team has made a sustained investment in DNSSEC deployment so that our customers don't get overwhelmed by this wave of changes to the core infrastructure of the Domain Name System. Along the way, we've learnt a lot about how to implement DNSSEC which might hold useful lessons for other organizations that plan to deploy DNSSEC in their networks. more
