China to Create National Cyberattack Database

China has revealed plans to create a national data repository for information on cyberattacks and will require telecom firms, internet companies and domain name service providers to report threats to it. more

What’s ARC?

DMARC is an anti-phishing technique that AOL and Yahoo repurposed last year to help them deal with the consequences of spam to (and apparently from) addresses in stolen address books. Since DMARC cannot tell mail sent through complex paths like mailing lists from phishes, this had the unfortunate side effect of screwing up nearly every discussion list on the planet. Last week the DMARC group published a proposal called ARC, for Authenticated Received Chain, that is intended to mitigate the damage. What is it, and how likely is it to work? more

Canadian Internet Registration Authority Launches Cloud-Based DNS Firewall Service

The Canadian Internet Registration Authority (CIRA) has announced the launch of a security service called D-Zone DNS Firewall -- a cloud-based cybersecurity solution -- to protect Canadian organizations from rasomware and malware. more

U.N. Approves Resolution to Combat Cybercrime Despite Opposition From E.U., the U.S. and Others

The U.N. General Assembly has approved a resolution to start the process of drafting a new international treaty against cybercrime despite objections from the European Union, the United States and other countries. The Russian-drafted resolution received approval from a 193-member world body with a vote of 79-60 and 33 abstentions. more

Nameserver Operators Need the Ability to “Disavow” Domains

Yesterday's DDoS attack against DNSimple brought to light a longstanding need for DNS nameserver operators to have an ability to unilaterally repudiate domains from their nameservers. The domains under attack started off on DNSMadeEasy, migrated off to DNSimple and took up residence there for about 12 hours, causing a lot of grief to DNSimple and their downstream customers. more

Unexpected Behaviour Observed With DNS Root Servers After Cryptographic Change

The DNS root servers were reported by Verisign to be under unexpected attack from name servers across the Internet following ICANN's recent changes to their cryptographic master keys. more

The Longevity of the Three-Napkin Protocol

It is not often I go out to my driveway to pick up the Washington Post -- yes, I still enjoy reading a real physical paper, perhaps a sign of age -- and the headline is NOT about how the (insert DC sports team here) lost last night but is instead is about an IT technology. That technology is the Border Gateway Protocol (BGP), a major Internet protocol that has been around for more than a quarter century, before the Internet was commercialized and before most people even knew what the Internet was. more

Bruce Schneier to Speak About Internet Surveillance at IETF 88 Technical Plenary Next Week

How do we harden the Internet against the kinds of pervasive monitoring and surveillance that has been in recent news? While full solutions may require political and legal actions, are there technical improvements that can be made to underlying Internet infrastructure? As discussed by IETF Chair Jari Arkko in a recent post on the IETF blog, "Plenary on Internet Hardening", the Technical Plenary at next weeks IETF 88 meeting in Vancouver, BC, Canada, will focus on this incredibly critical issue. more

Painting Ourselves Into a Corner with Path MTU Discovery

In Tony Li's article on path MTU discovery we see this text: "The next attempt to solve the MTU problem has been Packetization Layer Path MTU Discovery (PLPMTUD). Rather than depending on ICMP messaging, in this approach, the transport layer depends on packet loss to determine that the packet was too big for the network. Heuristics are used to differentiate between MTU problems and congestion. Obviously, this technique is only practical for protocols where the source can determine that there has been packet loss. Unidirectional, unacknowledged transfers, typically using UDP, would not be able to use this mechanism. To date, PLPMTUD hasn't demonstrated a significant improvement in the situation." Tony's article is (as usual) quite readable and useful, but my specific concern here is DNS... more

CAUCE Director Neil Schwartzman Wins Prestigious MAAWG Award

CAUCE Executive Director Neil Schwartzman won the prestigious Mary Litynski award on June 08, 2011 for his contributions to Internet anti-abuse efforts, including the passage of Canada's Anti-Spam Law. more

Black Hats, White Hats, Crackers and Bots

One of the other web sites I subscribe to is Stratfor. It's a global intelligence website and doesn't really have much to do with spam. But I like politics so I read it. They have some articles which you can get for free, but the better stuff you have to pay for. About two weeks ago, they ran a three-part series on Cyberwarfare. The first article was the title of this post, which you can access here (requires registration). In the article they described different types of cybercriminals and not-so-criminals which they referred to under the umbrella as "hackers." more

Use of DNS Firewalls Could Have Prevented More Than $10B in Data Breach Losses Over the Past 5 Years

New research from the Global Cyber Alliance (GCA) released on Wednesday reports that the use of freely available DNS firewalls could prevent 33% of cybersecurity data breaches from occurring. more

Cloud Computing Can Make You More Secure

The number one concern cited for avoiding cloud computing is security. And there is a reason for that. Cloud providers have demonstrated some spectacular failures in the past, including Amazon's near total shutdown of an entire region, Dropbox's authentication snafu, and innumerous cloud providers that go belly-up. However, in the long run, cloud computing is destined to become more secure than in-house IT. I will briefly describe two dynamics in the industry that point in that direction, with substantiating evidence. more

Anti-Phishing Working Group Proposes Use of Secure Hashing to Address GDPR-Whois Debacle

The AntiPhishing Working Group (APWG) in a letter to ICANN has expressed concern that the redaction of the WHOIS data as defined by GDPR for all domains is "over-prescriptive". more
