Google Exec: ISPs Must Get Tough on Malware Infested Computers on Their Networks

Ryan Naraine reporting at Threatpost: "Head of Google's anti-malvertising team Eric Davis wants Internet Service Providers (ISPs) to look beyond profits and take a more proactive approach to dealing with malware-infested computers on their networks. During a keynote presentation at the Virus Bulletin conference here, Davis said competitors in the ISP space must look beyond profits and partner on new initiatives to deal with the "parasites" that have taken control of the Internet landscape." more

DHS Asks Citizens to Practice Good “Cyber Hygiene”

Kicking off the sixth annual National Cybersecurity Awareness Month this October, the Department of Homeland Security (DHS) has urged computer users to practice good "cyber hygiene". The campaign was given a boost Wednesday when the Senate passed resolution 285 to support its goal to make U.S. citizens more aware of how to secure the internet. DHS has also announced that is has been given new authority to recruit and hire up to 1,000 cybersecurity professionals across the department to fill roles such as: cyber risk and strategic analysis; cyber incident response; vulnerability detection and assessment; intelligence and investigation; and network and systems engineering. more

In short, the decision implies that any form of the sequence of the characters "b", "a", "n", "k" are illegal in domain names in Sweden.

Helping Banks Fight Phishing and Account Fraud, Whether They Like It or Not

On Wednesday, Project Honey Pot filed an unusual lawsuit against "John Does stealing money from US businesses through unauthorized electronic transfers made possible by computer viruses transmitted in spam." Their attorney is Jon Praed of the Internet Law Group, who is one of the most experienced anti-spam lawyers around, with whom I have worked in the past. more

Routing Redundancy: How Much Is Enough?

Internet connectivity is a good thing. Many of us depend on it for everything from our livelihoods to our entertainment. However, the Internet is very fragile and even the The New York Times is worried about it. But they're primarily concerned with overloads that can occur when everyone on the planet does the same thing at roughly the same time, such as surfing for news about Michael Jackson. Unfortunately, we will never avoid all such scenarios. Physical systems are designed around average and typical peak loads, not around extremely high loads associated with very unlikely events. Who would pay for that? more

Why Can’t We Make the Internet Secure?

In a discussion about a recent denial of service attack against Twitter, someone asked, "Some class of suppliers must be making money off of the weaknesses. Anybody out there have a prescription for the cure?" Sure, but you're not going to like it. The Internet was originally a walled garden, where its operators knew who all the users were and could eject anyone who misbehaved... more

Cutting Through the Twitter DDoS Hype

There are a lot of theories flying around about why Twitter and other social media services got knocked offline yesterday. I've heard rumors about it being linked to political tension between Georgia and Russia. Others blame Iran for the outages. I'm not a political commentator, therefore I cannot comment on anyone's political views -- but I have some logic and common sense, and I can draw some objective conclusions. more

MAAWG Issues ISP Guidelines for End-User Bot Removal

Messaging Anti-Abuse Working Group (MAAWG) has issued the first best practices aimed at helping the global ISP industry work more closely with consumers to recognize and remove bot infections on end-users' machines. The paper outlines a three-step approach with recommendations for detecting bots, notifying users that their computers have been compromised, and guiding them in removing the malware. more

Think China Is the Highest Spamming Country? Think Again

In my department, we block about 92% of our total email (around 2.5 billion per day) at the network edge without accepting the message. When we do that, we don't see any traffic from that IP anymore and don't keep stats on it due to the overwhelming volume of mail. However, we do keep stats on mail that we block with our content filter. I decided to go and calculate how much spam we receive from each country by mapping the source IP back to its source country... more

New Analysis Suggests Recent Cyberattacks Against US and South Korea Originated from UK Not N. Korea

Nguyen Minh Duc, senior security director at Bach Khoa Internetwork Security (Bkis), says that the source of recent cyberattack against US and South Korean government websites was not North Korea -- as widely reported -- but UK. Based on Bkis analysis, a report today by Nguyen Minh Duc says that a master server located in UK was found to control the 8 Command and Control servers responsible for the series of cyberattacks last week.

Networks and Nationalization

This post isn't about -- or isn't only about -- the use of computer technology to commit crimes. It's more about the use of computer technology to commit war. A few weeks ago, I was part of a conversation about the legal issues cyberwarfare raises. We were talking about various scenarios -- e.g., a hostile nation-state uses cyberspace to attack the U.S. infrastructure by crippling or shutting down a power grid, air traffic control systems, financial system, etc. Mostly, we were focusing on issues that went to the laws of war, such as how and when a nation-state that is the target of a cyberattack can determine the attack is war, rather than cybercrime or cyberterrorism. more

Gary Warner: We Are Well Past Time to Declare a Spam Crisis in China

In a blog post last week, Gary Warner, director of research in computer forensics at the University of Alabama's (UAB) computer and information sciences department, wrote that it is well past time for someone to declare a "Spam Crisis in China". The warning comes along with UAB's reports that most of the spam they receive has ties to China. "It is very normal that more than one-third of the domain names we see each day in spam messages come from China," Warner wrote. "When one also considers the many '.com' and '.ru' domain names which are also hosted in China, the problem is much worse. More than half of all spam either uses domain names registered in China, is sent from computers in China, or uses computer in China to host their web pages." more

The Proxy Fight for Iranian Democracy

If you put 65 million people in a locked room, they’re going to find all the exits pretty quickly, and maybe make a few of their own. In the case of Iran’s crippled-but-still-connected Internet, that means finding a continuous supply of proxy servers that allow continued access to unfiltered international web content like Twitter, Gmail, and the BBC... more

Fight Phishing With Branding

Phishing, stealing personal information by impersonating a trusted organization, is a big problem that's not going away. Most antiphishing techniques to date have attempted to recognize fake e-mail and fake web sites, but this hasn't been particularly effective. A more promising approach is to brand the real mail and real web sites. more
