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

Typosquatted Domain Names Pose Plenty of Risk But Surprisingly Little Malware

A recent study took an in-depth look at the scale and the risk of domain name typosquatting -- the practice of registering mis-spellings of popular domain names in an attempt to profit from typing mistakes. "Applying every possible one-character typo to the domain names of Facebook, Google, Twitter, Microsoft, Apple and Sophos," Paul Ducklin, Sophos' Asia Pacific head of technology collected HTTP data and browser screenshots from 1502 web sites and 14,495 URLs. In this report, Ducklin analyses the data revealing unexpected results within the typosquatting ecosystem. more

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

91.3% of Malware Use DNS as a Key Capability

Nearly 92 percent of malware use DNS to gain command and control, exfiltrate data or redirect traffic, according to Cisco's 2016 Annual Security Report. It warns that DNS is often a security "blind spot" as security teams and DNS experts typically work in different IT groups within a company and don't interact frequently. more

Ready or Not… Here Come the IRC-Controlled SIP/VoIP Attack Bots and Botnets!

A story... ZZZ Telemarketing (not a real name) is locked in a heated fight with their bitter rival, YYY Telemarketing (also not a real name), to win a very large lead generation contract with Customer X. Customer X has decided to run a test pitting the two companies against each other for a week to see who can generate the most leads. The ZZZ CEO has said to his staff that it is "do or die" for the company. If they fail to win the contract, they will have to shut down -- they need to do "whatever it takes" to win over YYY. A ZZZ staffer discovers that part of why YYY has consistently underbid them is because they are using SIP trunks to reduce their PSTN connection costs. But the staffer also discovers that YYY is using very cheap voice service providers who run over the public Internet with no security... more

Google Chrome: Cloud Operating Environment

Rather than blathering on to the blogosphere about the superficial features of Google's new Chrome browser I've spent some time studying the available material and [re]writing a comprehensive Wikipedia article on the subject which I intend for anyone to be free to reuse under a Creative Commons Attribution 3.0 license rather than Wikipedia's usual strong copyleft GNU Free Documentation License (GFDL). This unusual freedom is extended in order to foster learning and critical analysis, particularly in terms of security. more

U.S. Critical Infrastructure Will Be Attacked Within 2 Years, According to 2017 Black Hat Survey

According to a 2017 Black Hat Attendee Survey, cyberattacks on U.S. enterprise and critical infrastructure are coming soon, and in most cases defenders are not prepared. more

No One is Immune: Qatar Crisis Started by a Targeted Poli-Cyber Attack

The Qatar Crisis started with a targeted Poli-Cyber hack of an unprecedented nature. Its shockwaves and repercussions continue to alter political and business fortunes, directions and paradigms not only in the Gulf region but globally. Almost everyone around the world is now aware of the this crisis that started early June. By mid July a Washington Post report cited US intelligence officials that the UAE orchestrated hacking of Qatari government sites, sparking regional upheaval that started it all. more

Garth Bruen Discussing Whois, DNSSEC and Domain Security

NameSmash has interviewed Garth Bruen, Internet security expert and creator of Knujon, on some key issues under discussion during the recent ICANN meetings in San Francisco. Topics include Whois, DNS Security Extensions (DNSSEC) and generic Top-Level Domains (gTLDs) -- issues of critical importance particularly with ICANN's expected roll-out of thousands of new gTLDs in the coming years. more

WannaCry: Patching Dilemma from the Other Side

WannaCry, originated firstly in state projects but spread by other actors, has touched upon myriads of infrastructure such as hospitals, telecommunication, railroads that many countries have labelled as critical. IT engineers are hastily presenting patching codes in various localized versions. The other patch needed, however, is more than technical. It is normative and legislative. The coding of that patch for a situation like this is in two layers of dilemma. more

M3AAWG Releases Anti-Abuse Best Common Practices for Hosting and Cloud Service Providers

Bashbleed - A Nasty Reminder Never to Forget Security 101

After the botched burglary at the Watergate Apartments, every scam and scandal that hit the headlines became a 'gate' -- Irangate, Contragate, you name it. The Heartbleed bug is possibly the closest thing to Watergate that this generation of computer security had seen till the past few days -- an exploit in a component that is "just there" -- something you utterly rely on to be there and perform its duties, and give very little thought to how secure (or rather, insecure) it might be. So, fittingly, every such catastrophic bug in an ubiquitous component is now a 'bleed'. more

Potential Danger Ahead for Registrants: dot-info Abusive Domain Use Policy

ICANN has posted a request by Afilias for a new registry service in relation to "abusive" domains in dot-info. While in general the proposal is motivated by good intentions, the devil is in the details. While most folks (including myself) probably care very little about the .info TLD, my concern is that any bad implementation in .info might be copied or used as a precedent in other more important TLDs, in particular .com run by VeriSign. more

China Hacks Google, Etc.

Many news sources are reporting on how Google and other corporations were hacked by China. The reports, depending on vendor, blame either PDF files via email as the original perpetrator, or lay most of the blame on an Internet Explorer 0day. more

State Hacking: Do’s and Don’ts, Pros and Cons

Over the past days a lot has been said and written on counter hacking by enforcement agencies. The cause is a letter Dutch Minister I. Opstelten, Security & Justice, sent to parliament. Pros and cons were debated and exchanged. Despite the fact that I perfectly understand the frustration of enforcement agencies of having to find actionable data and evidence that gets criminals convicted in a borderless, amorphous environment, a line seems to be crossed with this idea presented to Dutch parliament. Where are we? more
