What Next for Email Service Providers?

It's been a very bad month for ESPs, companies that handle bulk mailings for their clients. Several of them have had internal security breaches, leaking client information, client mailing lists, or both. Many have also seen clients compromised, with the compromised credentials used to send spam. The sequence of events suggests all the ESPs whose clients were compromised were themselves compromised first. (That's how the crooks knew who to attack.) more

How to Avoid Insider Threats Such as the Latest New York Post Hacking

New York Post has been "hacked" by an employee. To protect themselves from insider threats, companies can deploy zero trust and restrict access. On October 27, the New York Post published a string of racist and sexist articles on its website. Fabricated news about politicians, such as pieces concerning racist comments of a New York City mayor, has been headlining the publication. more

Researchers Use Social Graphs to Detect Spammers, Attackers

Phishing Attacks Surge Despite Increased Awareness, New Strategies Needed

The alarming rise of phishing attacks has been underscored by a recent study "Phishing Landscape 2023: An Annual Study of the Scope and Distribution of Phishing conducted" by the Interisle Consulting Group, revealing a tripling of such attacks since May 2020. Despite efforts by companies and policymakers to combat this cybercrime, the data suggests that the prevailing strategies are ineffective and worsening each year. more

We Must Keep Track of How Countries Will Confront Cybercrime in a New UN Convention

As a designated committee of experts prepares to draft a new treaty to combat the use of information and communications technologies in cybercrime at the UN in January 2022, it is paramount that other stakeholders oversee these discussions to avoid violating human rights on the Internet. This initiative was kickstarted by a 2019 resolution led by Russia and endorsed by other countries considered by many to behavior controversially on cybersecurity matters, such as China, Venezuela, Cambodia, North Korea, and others. more

How to Choose a Cyber Threat Intelligence Provider

Throughout the course of my career I've been blessed to work with some of the most talented folks in the security and cyber threat intelligence (CTI) mission space to create a variety of different capabilities in the public, private and commercial sectors. Before I came to lead the Verisign iDefense team about five years ago, I had to evaluate external cyber-intelligence vendors to complement and expand the enterprise capabilities of my former organization. more

Phishing: Competing on Security

The UK today is one of the main attack targets by phishing organized crime groups, globally. Phishing damages will amount to about two billions USD in 2006 worldwide -- not counting risk management measures such as preventative measures, counter-measures, incident response and PR damages. In most cases, phishing is caused by the fault of the users, either by entering the wrong web page, not keeping their computers secure or falling for cheap scams. Often this is due to lack of awareness or ability in the realm of Internet use rather than incompetence by the users... 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

Clarke and Knake’s “Cyberwar”

I just finished reading Richard Clarke and Robert Knake's book Cyberwar. Though the book has flaws, some of them serious, the authors make some important points. They deserve to be taken seriously. I should note that I disagree with some of my friends about whether or not "cyberwar" is a real concept. Earlier, I speculated that perhaps it might be a useful way to conduct disinformation operations, but it need not be so limited. more

Blocking a DDoS Upstream

In the first post on DDoS, I considered some mechanisms to disperse an attack across multiple edges (I actually plan to return to this topic with further thoughts in a future post). The second post considered some of the ways you can scrub DDoS traffic. This post is going to complete the basic lineup of reacting to DDoS attacks by considering how to block an attack before it hits your network -- upstream. more

Maintaining Security and Stability in the Internet Ecosystem

DDoS attacks, phishing scams and malware. We battle these dark forces every day - and every day they get more sophisticated. But what worries me isn't just keeping up with them, it is keeping up with the sheer volume of devices and data that these forces can enlist in an attack. That's why we as an industry need to come together and share best practices - at the ICANN community, at the IETF and elsewhere - so collectively we are ready for the future. more
