Well... Maybe not the world, but the Internet it seems. According to a Pastebin letter, Anonymous announced they will black-out Internet on 31st of March. They even explained how to do it by attacking the DNS Root Servers on Internet using a reflected amplification attack. If this is successful, the root DNS servers will become unresponsive and cannot handle any other requests... more
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
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
With cybercrime on the rise, companies in 2021 have experienced increased ransomware attacks, business email compromise (BEC), phishing attacks, supply chain attacks, and online brand and trademark abuse. While domain cyber risk is rising, the level of action being taken by Forbes Global 2000 companies to improve their domain security posture has remained unchanged, leaving these companies exposed to even more risk. The risk of not addressing your domain security can be catastrophic. 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
IT security strategies invariably focus on maintaining impenetrable fortresses around computers and network systems. Firewalls, virtual private networks and anti-virus programs are the tools IT engineers use to create their digital security. Sophisticated defense systems can be very effective at keeping the obvious attackers at bay, yet they often create a false sense of security because the real attacks, the kind that inflict irreparable damage on a system or network, avoid the obvious routes into the secure fortress. more
News broke this week about an attack in Puerto Rico that caused the local websites of Google, Microsoft, Yahoo, Coca-Cola, PayPal, Nike, Dell and Nokia to be redirected for a few hours to a phony website. The website was all black except for a taunting message from the computer hacker responsible for the attack... more
The following provides and introduction to a study by Venugopalan Ramasubramanian and Emin Gun Sirer, called "Perils of Transitive Trust in the Domain Name System". The paper presents results from a large scale survey of DNS, illustrating how complex and subtle dependencies between names and nameservers lead to a highly insecure naming system... "It is well-known that nameservers in the Domain Name System are vulnerable to a wide range of attacks. We recently performed a large scale survey to answer some basic questions about the legacy DNS." more
A large scale ransomware attack today is spreading rapidly worldwide, shutting down computers at corporates, power supplies, and banks across Russia, Ukraine, Spain, France, UK, India, and Europe and demanding $300 in bitcoins. more
There's a lot of misunderstanding about blockchain. A recent study by HSBC, for example, found that 59 percent of customers around the world had never heard of it. Yet, while that alone is quite telling, it's probably more alarming to consider the fact that very same poll revealed that 80 percent of people who had hard of blockchain did not understand what it is. This level of confusion isn't confined to the general population either. more
According to Akamai, the incident was the largest attack seen to date, "more than twice the size of the September 2016 attacks that announced the Mirai botnet and possibly the largest DDoS attack publicly disclosed." more
The Equifax hack is understood to have compromised the personal data of over 140 million individuals. Although recent hacks of other businesses have affected more individuals, the personal data held by Equifax is significantly more sensitive than the data compromised in other hacks and includes Social Security numbers, birth dates, current and previous addresses and driver licence details... (Co-authored by Peter Davis and Brendan Nixon.) more
The Russian Security Council has proposed development of an independent DNS which would continue to work in the event of global internet malfunctions, according to a report from RT. more
The following is an overview of the recent Honeynet Project and Research Alliance study called 'Know your Enemy:Phishing' aimed at discovering practical information on the practice of phishing. This study focuses on real world incidents based on data captured and analyzed from the UK and German Honeynet Project revealing how attackers build and use their infrastructure for Phishing based attacks. "This data has helped us to understand how phishers typically behave and some of the methods they employ to lure and trick their victims. We have learned that phishing attacks can occur very rapidly, with only limited elapsed time between the initial system intrusion and a phishing web site going online..." more
The DNS Abuse Institute recently published our sixth monthly report for our project to measure DNS Abuse: DNSAI Compass ('Compass'). Compass is an initiative of the DNS Abuse Institute to measure the use of the DNS for phishing and malware. The intention is to establish a credible source of metrics for addressing DNS Abuse. We hope this will enable focused conversations, and identify opportunities for improvement. more
