Cyber Threats Yes, But Is It Cyber War?

Last night Intelligence Squared and Neustar conducted a fascinating, Oxford style debate on whether the threat of cyber war has been exaggerated. A packed house at the Newseum in Washington, DC heard four cyber heavyweights go toe-to-toe verbally both for and against the proposition that the threat has been exaggerated. 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

SEC Reinforces and Expands Its Cybersecurity Guidance for Public Companies

The Securities and Exchange Commission has issued an updated guidance for public companies in preparing disclosures about cybersecurity risks and incidents. more

Mitigating Spoofed Attacks Using IPv6 Address Space

Timothy D. Morgan's recent paper titled, "IPv6 Address Cookies", seeks to apply the fundamental shift in resource availability brought about by the vastly increased Internet address space in IPv6 to develop a novel, lower cost solution to mitigating spoofed attacks. "Spoofed denial of service attacks have plagued the Internet for a number of years, and show no signs of abating. Research into mitigation techniques has apparently not led to a financially viable solution, and new attacks have been discovered in the wild without being widely anticipated". The following provides an introduction to this paper. more

New Study Highlights Growing Risk, Lack of Urgency with Mobile and IoT Application Security

Despite widespread concern about the security of mobile and Internet of Things (IoT) applications, organizations are ill-prepared for the risks they pose, according to a research report issued today from Ponemon Institute, IBM Security, and Arxan Technologies. more

NeuStar Experiences Partial Outage as DynDNS Tries to Turn up the Heat

NeuStar's UltraDNS faced attack on two fronts on Tuesday, March 31. One of the attacks was technical -- a massive denial-of-service attack. The second was a rather surprising opening strike from competitor Dynamic Network Services (DynDNS), which launched a full-scale (and in T1R's opinion, misguided) public relations broadside. First, to the actual denial of service attack. Contrary to many early reports, UltraDNS was not 'down' on Tuesday... more

Estonian Cyber Security Strategy Document: Translated and Public

The Estonians have a public version of their cyber security strategy translated into English (currently available offline only). The concept of a national strategy for cyber security is one which I am particularly fond of... The following is the Summary section from the document which might be of interest... more

Hackers Hijack DNS Server for Cyrptocurrency Wallet BlackWallet, Over $400K Stolen From Users

Unknown hackers (or hacker) have hijacked the DNS server for BlackWallet.co, a web-based wallet application for the Stellar Lumen cryptocurrency (XLM). 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

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

Brand Impersonation Online is a Multidimensional Cybersecurity Threat

Brand impersonation happens much more often than people realize. In CSC's latest Domain Security Report, we found that 75% of domains for the Global 2000 that contained more than six characters from the brand names were not actually owned by the brands themselves. The intent of these fake domain registrations is to leverage the trust placed on the targeted brands to launch phishing attacks, other forms of digital brand abuse, or IP infringement... more

A Digital ‘Red Cross’

A look into the past reveals that continuous developments in weaponry technology have been the reason for arms control conventions and bans. The banning of the crossbow by Pope Urban II in 1096, because it threatened to change warfare in favour of poorer peasants, the banning of poisoned bullets in 1675 by the Strasbourg Agreement, and the Geneva protocol banning the use of biological and chemical weapons in 1925 after world war 1, all prove that significant technological developments have caused the world to agree not to use certain weapons. more

The Latest DNS Threat Landscape: Why CISOs Must Rethink Blocking Strategies

Cybercriminals live by the tenet "If it ain't broke, don't fix it." They'll use the same tactics repeatedly until they no longer work, then switch things up. That's why CISOs and their security teams maintain constant vigilance. Underscoring this, recent analysis of global DNS activity found that new domains continue to be a major tactic for bad actors. more

Two More Crypto Holes

If you work in computer security, your Twitter feed and/or Inbox has just exploded with stories about not just one but two new holes in cryptographic protcols. One affects WiFi; the other affects RSA key pair generation by certain chips. How serious are these? I'm not going to go through the technical details. For KRACK, Matthew Green did an excellent blog post; for the other, full details are not yet available. There are also good articles on each of them. What's more interesting are the implications. more

Policy Failure Enables Mass Malware: Part I (Rx-Partners/VIPMEDS)

This is the first in a series of releases that tie extensive code injection campaigns directly to policy failures within the Internet architecture. In this report we detail a PHP injection found on dozens of university and non-profit websites which redirected visitor's browsers to illicit pharmacies controlled by the VIPMEDS/Rx-Partners affiliate network. This is not a unique problem, however the pharmacy shop sites in question: HEALTHCUBE[DOT]US and GETPILLS[DOT]US should not even exist under the .US Nexus Policy. more
