In February 2012, Neustar surveyed IT professionals across North America to better understand their DDoS experiences. Most were network services managers, senior systems engineers, systems administrators and directors of IT operations. In all, 1,000 people from 26 different industries shared responses about attacks, defenses, ongoing concerns, risks and financial losses. more
One of the big trends this year is spear phishing. These are phish attacks that are frequently (though not always) against high profile users. The purpose of these attacks is to steal sensitive data or get elevation of privilege inside the service by exploiting a software vulnerability within the user's computer that transmits usernames and passwords back to the phisher. more
The outbreak of COVID-19 has caused worldwide disruption -- for whole nations and their economies. Unfortunately, there will be some side effects for businesses. A number of brands will disappear from the streets and shelves, as businesses that fail to weather the storm will have to fold. Companies that do survive will likely focus more on their core markets, pulling brands out of higher risk, less profitable markets... more
The indicators of compromise (IOCs) outlined in my last blog post can be used as a baseline for developing intrusion sets and tracking attack campaigns and threat actors. When launching an attack, threat actors use a variety of vectors and infrastructure, which Verisign iDefense analysts -- as well as analysts across the cybersecurity community -- correlate to group attacks, tracking actors and determining attack methods. more
The world is abuzz this week with some flaming malware - well "Flame" is the family name if you want to be precise. The malware package itself is considerably larger than what you'll typically bump into on average, but the interest it is garnering with the media and antivirus vendors has more to do with the kinds of victims that have sprung up - victims mostly in the Middle East, including Iran - and a couple of vendors claiming the malware as being related to Stuxnet and Duku. more
The distribution and installation of malicious and unauthorized software has evolved consistently throughout the 21st Century. The evolutionary path from annoying viruses, to destructive malware and on to financially driven crimeware, is well documented and can even be conveniently traced via the parallel evolution of technologies that were designed to counter each new aspect of the then contemporary threat. more
On Nov. 30 and Dec. 1, several of the Internet Domain Name System's root name servers received high rate of suspicious queries, reaching as high as 5 million queries per second, according to a report released by the Root Server System Advisory Council. The incident has been categorized as a unique type of DNS amplification attack. more
Very few African states today have developed a national cybersecurity strategy or have in place cybersecurity and data protection regulations and laws. Yet, the continent has made major headway in developing its digital ecosystem, and moreover, it is home to the largest free trade area in the world, which is predicted to create an entirely new development path harnessing the potential of its resources and people. more
As a bit of a history buff I can't avoid a slight tingling of déjà vu every time I read some new story commenting upon the ethics, morality and legality of cyber-warfare/cyber-espionage/cyberwar/cyber-attack/cyber-whatever. All this rhetoric about Stuxnet, Flame, and other nation-state cyber-attack tools, combined with the parade of newly acknowledged cyber-warfare capabilities and units within the armed services of countries around the globe, brings to the fore so many parallels... Call me a cynic if you will, but when the parallels in history are so evident, we'd be crazy to ignore them. more
BGP. Border Gateway Protocol. The de-facto standard routing protocol of the Internet. The nervous system of the Internet. I don't think I can overstate the importance, the criticality of BGP to the operation of the modern Internet. BGP is the glue that holds the Internet together at its core. And like so many integral pieces of the Internet, it, too, is designed and built on the principle of trust... The folks who operate the individual networks that make up the Internet are generally interested in keeping the Internet operating, in keeping the packets flowing. And they do a great job, for the most part. more
We are suffering an epidemic of cyberattacks while in a viral pandemic. This post is for those who have responsibility for assuring that the IT-based services offered by their enterprise can quickly recover in the case of successful cyber-attack or other disaster. University of Vermont Medical Center (UVMMC) is an excellent hospital. I owe my life to treatment there and am grateful for both the skill and the kindness of UVMMC staff. They have been devastated by a cyber-attack. more
As industries from agriculture to banking increasingly depend on space-based capabilities, safeguarding satellites from cyber threats has become paramount. In a groundbreaking move to address this, the U.S. military will stage Hack-A-Sat 4, a competition at the famed DEFCON hacker convention, inviting white-hat hacker teams to attempt to infiltrate and control computer systems on a satellite in orbit. more
If this past quarter's stories are any indication, we could very well be seeing the rise of a new wave of threats that will affect people in a more pronounced and physical level, reports Trend Micro in its Q2 Security Roundup Report. more
The movement for upping the minimum wage in the US is gathering momentum. Protests and placard waving are on the increase, and the quest for $15 per hour is well underway. There are plenty of arguments as to why such a hike in minimum wage is necessary, and what the consequences could be to those businesses dependent upon the cheapest hourly labor. But, for the information security industry, upping the minimum wage will likely yield only good news. more
In this multipart series I will be presenting some of the leading industry-standard best practices for enterprise network security using Cisco technologies... In Part 1 of this series, I provided an overview of the critical role that properly designed data security architectures play within an Internet-connected organization. Before we begin to discuss the security designs, processes and recommendations related to Cisco technology, let's first discuss some of the ways a network becomes unsecure... more
