Taking the Leap to Cloud-Based Malware Inspection

Is desktop anti-virus dead? Someday I'd love to make that announcement, but it still feels to me that there's a Patron Saint of Voodoo with an affinity for bringing it back to life -- like some macabre mirror image of the malicious zombies it's supposed to provide protection against. It's kind of ironic that today's innovation in desktop anti-virus isn't really happening at the desktop; rather it's occurring in the cloud. more

The Sins of the Flash

Recent news stories (based on research by Stanford student Feross Aboukhadijeh) state that an Adobe bug made it possible for remote sites to turn on a viewer's camera and microphone. That sounds bad enough, but that's not the really disturbing part. 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

The Human Factor in DDoS Attacks

Ripped from the headlines: A recent DDoS attack lasted an entire 60 days. In other news, a single site was attacked 218 times in Q2 alone. To those of us in the business of protecting Web infrastructure, these stories are hardly surprising. What's notable, though, is where they were reported, in The Financial, whose focus is banking and financial services, not technology. The reporters used the term "DDoS" as if it were as common as "hedge fund," something everyday business people, not just techies, grasp. It's this human element that caught my interest and got me thinking a little. 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

Typosquatting Continues to Pose Dangers to Enterprises, Consumers

While typosquatting is not a new phenomenon, recent research highlights that it is being used to collect sensitive corporate information from employees and lure consumers to interact with dubious websites. ... Security consultancy Godai Group recently uncovered the use of a specific type of typosquat - a "doppelganger domain" - to collect sensitive enterprise information via email-based attacks. more

DKIM for Discussion Lists

There's a pernicious meme floating around that DomainKeys Identified Mail (DKIM) doesn't work with discussion lists, particularly those hosted on common open source software packages like MailMan. It's particularly odd to see this claim after I set it up successfully on a stock Debian server in less than half an hour, just a few weeks ago. Here's how it can, should, and does work. more

Hacking Away at the Internet’s Security

The front page story of the September 13 2011 issue of the International Herald Tribune said it all: "Iranian activists feel the chill as hacker taps into e-mails." The news story relates how a hacker has "sneaked into the computer systems of a security firm on the outskirts of Amsterdam" and then "created credentials that could allow someone to spy on Internet connections that appeared to be secure." According to this news report this incident punched a hole in an online security mechanism that is trusted by hundreds of millions of Internet users all over the network. more

DNSSEC Takes Off in Wake of Root Zone Signing

The Domain Name System Security Extensions (DNSSEC) is a suite of IETF-developed specifications designed to validate information provided by the Domain Name System (DNS). ... When the root zone was signed in June 2010, this acted as a catalyst for TLD operators to deploy DNSSEC on their side. We have seen a gradual but significant increase in signed TLDs since then. The map in this post shows the level of DNSSEC deployment in Europe. more

Is Cybersecurity a Priority? You Wouldn’t Know It If You Go by Top Level Defections

In the US administration, we see important people like incoming Secretary of Defense Leon Panetta say at his Senate confirmation hearing that "a strong likelihood that the next Pearl Harbor" could well be a cyberattack that cripples the U.S. power grid and financial and government systems. He also said that cybersecurity will be one of the main focuses of his tenure at the Pentagon. But when you look at what is actually happening in cyber security, there is more position jockeying than there is real progress. more

Alignment of Interests in DNS Blocking

I've written recently about a general purpose method called DNS Response Policy Zones (DNS RPZ) for publishing and consuming DNS reputation data to enable a market between security companies who can do the research necessary to find out where the Internet's bad stuff is and network operators who don't want their users to be victims of that bad stuff... During an extensive walking tour of the US Capitol last week to discuss a technical whitepaper with members of both parties and both houses of the legislature, I was asked several times why the DNS RPZ technology would not work for implementing something like PROTECT-IP. more

Why Isn’t Mobile Malware More Popular?

This is a followup to Wout de Natris' as usual excellent piece on the Enisa botnet report -- pointing out the current state of mobile malware and asking some questions I started off answering in a comment but it grew to a length where I thought it'd be better off in its own post. Going through previous iterations of Mikko's presentations on mobile malware is a fascinating exercise. more

Why Private Support of Cyber Security Initiatives May Not Work

A fledgling international cyber security alliance is continuing to gather backing from private business, according to a recent article published on ComputerWeekly.com. The International Cyber Security Protection Alliance (ICSPA) aims to support law enforcement agencies in countries that lack the resources to fight cybercrime. Commercial security organizations such as McAfee and Trend Micro are supporting the alliance. more

Independence and Security Online Have Not Yet Been Won

As we, here in the United States celebrate our independence this Fourth of July, we are reminded that the liberties and freedoms that come with that independence have yet to be won online. As citizens of this country we are blessed with safety and security from threats both foreign and domestic, but those guarantees have not yet extended to our citizenship in the global Internet community. This is true not just for American citizens, but for all Internet users throughout the world. more

Searching Under Lampposts with DKIM

Email is a complex service and email abuse adds confusing deceptions. Worse, like postal mail and even telephone service, Internet mail is inherently open, flexible and even anonymous, making things much easier for abusers. Bad actors hide their true identity and their true purpose. Most other communication tools for users also are also quite open, and problems with email are being replicated elsewhere, such as instant messaging and social media. more
