SAML Certificate Security: The Latest Findings and Potential Impacts

Recently, the National Security Agency (NSA) published new findings that reference how previously discovered tactics, techniques, and procedures (TTPs) abusing federated authentication could be used in conjunction with on-premises network access to gain broad access across an organization’s applications. The Cybersecurity and Infrastructure Agency (CISA) has also updated its bulletin to include these attacks, and Microsoft has also published insights. This advisory comes on the heels of the...

More Than Subdomain Takeover: Ways To Takeover, Hijack And Impersonate Your Website

In my last post about subdomain takeovers, we talked about what subdomain takeovers are and how hackers can use them to attack shared-session SSO. Today, let’s dive deeper into subdomain takeovers and some other ways hackers can hijack your website. Subdomain Takeover Recap Subdomain takeover is when a hacker takes control over a company’s unused subdomain. It happens when a stale DNS entry points to a domain that is available for registration.

Building A Subdomain Takeover Monitor

In a previous article, we talked about the different types of subdomain takeovers and how hackers can use them to attack SSO systems. The impact of a subdomain takeover can vary. At the very least, subdomain takeovers enable attackers to launch sophisticated phishing campaigns. In some cases, this can lead to Cross-Site Scripting (XSS) attacks or malicious redirects. And, when a site uses shared-session SSO, this could even lead to session theft and account takeovers! Unfortunately, subdomain...

Password Spraying Attacks and How to Prevent Them

Have you heard of password brute-force attacks? A brute-force attack is when attackers try to compromise an account by guessing its password. Let’s say an attacker is trying to compromise the account of the user “john” by brute-forcing the account password. The attacker will first generate a password list to use. They can either use a dictionary of common passwords found online, or a list of likely passwords generated based on knowledge of the user. Then, the attacker uses a script to rapidly...

Why Bitsquatting Attacks Are Here to Stay

Typos have a long history, by turns serious and silly, going back to the dawn of the printed page. But thanks to the peculiarities of computer technology and the ingenuity of hackers, correctly typing website locations into your browser is no guarantee that they will show you the site you intended to view. When machines make typos even with correct human input, the errors can lead to an unusual form of cyber attack known as bitsquatting. The younger sibling of typosquatting, bitsquatting is...

The State of Election Security

Clichéd as the concept of a perfect storm is, it also feels more apt than ever to describe this year’s American election—and that’s only taking into consideration the cybersecurity challenges voters face. Since 2016, cybersecurity and election experts have been sounding an ever-louder clarion call that aggressive steps need be taken to ensure that computerized voting machines in the U.S. are secure enough to properly enroll registered voters, record their votes, and accurately count them, as...

kPop Fans: Non-Traditional, Non-State Actors

kPop Fans The nature of a strategic cyber force is far richer and more varied than is traditionally acknowledged. Earlier this year, Korean pop (“kPop”) music fans came to wider attention when they actively engaged with online political discussions around Black Lives Matter. This is not the first time they have been a well organised online force, but as far as we know, this is the first time they’ve taken part in a broader popular movement.  kPop fans have a years-long history of political...

A Quick Look at the 2020 Threat Landscape

There’s no doubt 2020 has already been a turbulent year: COVID-19, civil unrest, contentious elections, widespread economic instability, and major natural disasters like wildfires and hurricanes across the US are just a few of the major events making headlines. While digital threats often echo real-world events, perhaps none has had a greater impact on the threat landscape this year than COVID-19. As municipalities adopted social distancing measures and many workers shifted to remote work,...
