Cybersecurity

Person to Person Security and Privacy Infringement

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

Taking the Leap to Cloud-Based Malware Inspection

Is desktop anti-virus dead? Someday I'd love to make that announcement, but it still feels to me that there's a Patron Saint of Voodoo with an affinity for bringing it back to life -- like some macabre mirror image of the malicious zombies it's supposed to provide protection against. It's kind of ironic that today's innovation in desktop anti-virus isn't really happening at the desktop; rather it's occurring in the cloud. more

91.3% of Malware Use DNS as a Key Capability

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

How Registrants Can Reduce the Threat of Domain Hijacking

Because domain names represent the online identity of individuals, businesses and other organizations, companies and organizations large and small have expressed increasing concern over reports of "domain name hijacking," in which perpetrators fraudulently transfer domain names by password theft or social engineering. The impact of these attacks can be significant, as hijackers are typically able to gain complete control of a victim's domain name - often for a significant period of time. more

Upcoming Latin America and Caribbean DNS Forum

The Latin America and Caribbean Domain Name System (LAC DNS) Forum will be held on November 15, 2013 in Buenos Aires, Argentina. This follows on a similar initiative that took place at ICANN 47 in Durban, South Africa. The event's global, regional and local organizers plan to address key online issues, including more regional involvement with Internet governance. more

Do Agencies Already Have the Authority to Issue Critical Infrastructure Protection Regulations?

The President and Congress are deliberating how best to ensure appropriate cybersecurity protection for private sector critical infrastructure. Legislative action and Executive Order are both under consideration. It is possible, however, that the White House Office of Management and Budget (OMB) already has sufficient statutory authority to enact new cybersecurity regulations through the normal notice-and-comment rulemaking process. more

As IPv6 Deploys, Will We Look Back on NAT as the Ugly Step Sister or Unsung Hero?

The debates are raging over whether or not we should migrate to IPv6. The strongest argument is the enormous address space that will allow for everyone and everything to have a unique public address, many addresses actually. It is often said that the shortage of public IPv4 addresses has limited our capabilities because it led to the pervasive use of private addressing, Network Address Translation (NAT) and Port Address Translation (PAT). Though these technologies remain critical, they are often regarded as stop-gap measures, and they sometimes create problems. In some circles, NAT has acquired a very bad name. But is that a fair perspective of the technology? Let's review the positives and negatives. more

Key Findings from the 2021 Domain Security Report

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

End of the World/Internet on 31-March-2012?

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

New Study Revealing Behind the Scenes of Phishing Attacks

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

Why Foldering Adds Very Little Security

I keep hearing stories of people using "foldering" for covert communications. Foldering is the process of composing a message for another party, but instead of sending it as an email, you leave it in the Drafts folder. The other party then logs in to the same email account and reads the message; they can then reply via the same technique. Foldering has been used for a long time, most famously by then-CIA director David Petraeus and his biographer/lover Paula Broadwell. Why is foldering used? more

Ready or Not… Here Come the IRC-Controlled SIP/VoIP Attack Bots and Botnets!

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

ICANN DNS Resolver Symposium – the Session Had Several Interesting Presentations That I Would Like to Comment On

ICANN hosted a Resolver Operator Forum in mid-December, and the session had several interesting presentations that I would like to comment on here... The first presentation in this forum was from Paul Mockapetris. He pointed to the original academic published paper, Development of the Domain Name System, by Paul Mockapetris and Kevin Dunlap, published in the proceedings of ACM SIGCOMM’88. The paper noted that by 1983 it was obvious that the shared HOSTS.TXT file was not a scalable solution... more

Russia in Talks to Create Independent DNS

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

U.S. Critical Infrastructure Will Be Attacked Within 2 Years, According to 2017 Black Hat Survey

According to a 2017 Black Hat Attendee Survey, cyberattacks on U.S. enterprise and critical infrastructure are coming soon, and in most cases defenders are not prepared. more
