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
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
Unknown hackers (or hacker) have hijacked the DNS server for BlackWallet.co, a web-based wallet application for the Stellar Lumen cryptocurrency (XLM). more
Satellites make it possible for governments to provide essential services, such as national defense, navigation, and weather forecasting. Private ventures use satellites to offer highly desired services that include video program distribution, telecommunications, and Internet access. The Russian launch of a satellite, with nuclear power and the likely ability to disable satellites, underscores how satellites are quite vulnerable to both natural and manmade ruin. more
According to report today, Russian-speaking hackers called MoneyTaker, are suspected of stealing nearly $10m by removing overdraft limits on debit cards and taking money from cash machines. more
As warned by Dan Kaminsky, Paul Vixie, and numerous other experts experts, it was just a matter of time before an exploit code for the now public DNS flaw would surface. An exploit code for the flaw allowing insertion of malicious DNS records into the cache of target nameservers has been posted to Metasploit, a free provider of information and tools on exploit techniques. According to reports Metasploit creator, H D Moore in collaboration with a researcher named "|)ruid" from Computer Academic Underground, created the exploit, dubbed "DNS BaliWicked Attack", along with a DNS service created to assist with the exploit. more
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
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
One of the problems with trying to secure systems is the lack of knowledge in the community about what has or hasn't worked. I'm on record as calling for an analog to the National Transportation Safety Board: a government agency that investigates major outages and publishes the results. In the current, deregulatory political climate, though, that isn't going to happen. But how about a voluntary system? more
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
Many of you will have seen news stories that explained what was going on: a huge DDoS attack on the infrastructure of Dyn had taken down access to many large websites like Twitter. A great deal of digital ink has since been spilled in the mainstream press on the insecurity of the Internet of Things, as a botnet of webcams was being used. Here are some additional issues that might get missed in the resulting discussion. more
The sky is falling! The sky is falling! ...or is it? What is this thing called "pharming"? Put simply, it's redirection of web traffic, so that the server you think you're talking to actually belongs to a criminal. For example: you think you're talking to www.examplebank.com because it says so in the browser's address bar, but actually you're connected to www.mafia-R-us.ru. This can happen in three main ways: 1. DNS Hijack: a social engineering attack on the Internet infrastructure... more
According to a press release by the Openbaar Ministerie (the Public Prosecution Office), a dutch man with the initials SK has been arrested in Spain for the DDoS attacks on Spamhaus. more
I consult on communication issues for Neustar, an Internet infrastructure company. As most CircleIDers know, Neustar works behind the scenes to ensure the smooth operation of many critical systems like DNS, .us and .biz, local number portability and digital rights management. One of the cool things about working for them is the chance to attend the events they sponsor. Last week Neustar held a security briefing for senior federal IT personnel focused on Cybersecurity and Domain Name System Security Extensions (DNSSEC)... more
A recent paper called "Worm Propagation Strategies in an IPv6 Internet", written by Steven M. Bellovin, Angelos Keromytis, and Bill Cheswick, examines whether or not the deployment of IPv6 will in fact provide a substantial level of barrier against worms. Shared below are the introductory paragraphs from this paper. "In recent years, the internet has been plagued by a number of worms. One popular mechanism that worms use to detect vulnerable targets is random IP address-space probing..." more
