Domain Defense in 2024: Why Takedowns Matter

With over 628.5 million websites pulsating on the Internet, phishing attacks skyrocketing, and web applications at the top of the heap for attack vectors, the urgency to strengthen cybersecurity and domain security measures has never been greater. One effective strategy to undermine an adversary’s domain-based operations involves executing domain takedowns. Although not a new tactic, the effectiveness and relevance of domain takedowns continue to be debated.

Contrary to popular belief, these traditional cybersecurity measures are surviving and thriving amidst technological advances. I’d even say that new technology makes them more valuable. Let’s explore how domain takedowns augment a broader proactive cybersecurity posture and improve the effectiveness of an organization’s security strategy.

‘Security Mesh’ is Reactive, and That’s Not Enough

Most infosec teams employ a ‘security mesh’ strategy, consisting of layered defenses centered on detection and response tools that pinpoint and alert on malicious activities. However, this approach is inherently reactive, often leaving organizations vulnerable to new, novel cyberattacks.

In response to this vulnerability, many cybersecurity experts are adopting proactive security measures, employing advanced strategies to disrupt and neutralize threats before they can act. Security teams can preemptively identify and stop emerging attack vectors by enhancing their defenses with cutting-edge tools that utilize Large Language Models (LLMs), including machine learning and artificial intelligence.

A Persistent Threat & The Role of Domain Takedowns

Before delving into the relevance of domain takedowns, let’s clarify what they involve and why they remain relevant and critical.

As mentioned earlier, there are approximately 628.5 million websites globally and growing. The Anti-Phishing Working Group (APWG) identified over one million phishing sites in the last quarter of 2023. Notably, fraudulent sites targeting social media users represented 43% of these malicious domains, with SaaS companies (15%) and financial institutions (14%) closely behind. This means 72% of phishing domains are concentrated in these key areas. By swiftly removing these malicious sites, organizations can protect their customers and preserve their reputations.

Anatomy of a Takedown

A malicious domain takedown starts when a fraudulent actor replicates an organization’s website under a deceptively similar domain name, then targets the organization’s customers, urging them to engage in actions like downloading fake applications or making payments. These domains are purposefully designed to deceive and defraud, damaging the business’s reputation and its customer trust.

The “takedown” process involves removing these websites by officially notifying their hosting providers and registrars. Key details such as registrar information, mail records, and hosting data are used to establish proof of misuse. A complaint is lodged typically through a detailed “abuse” email or by filling out a form to the registrars. Once submitted, the DNS registry assigns a status code that determines the success of the takedown. The effectiveness and speed of this process vary widely, reflecting the scale and complexity of managing numerous domain takedowns simultaneously.

Setting the Bar: Criteria for Launching a Takedown

Determining whether to initiate a domain takedown involves a set of specific criteria that prove the malicious nature of a website. For a site to be flagged for a takedown, it must meet several indicators of fraud:

  1. Presence of active malicious content that closely mimics a legitimate site.
  2. Discussions by customers or users identifying the site as part of a scam, often including victim testimonies.
  3. The site has functionality for payments or harvesting Personally Identifiable Information (PII), which could be used in broader social engineering attacks.
  4. Registrant details that conflict with the legitimate website’s ownership information.
  5. Appearance of unusual characters, spelling errors, or inconsistent fonts that signal illegitimacy.
  6. Recent website registration compared to the established presence of the genuine company, often with domain settings poised to expire quickly after fulfilling its fraudulent purpose.

The decision to proceed with a takedown is crucial during the first 24-72 hours after a domain’s registration—this “golden” timeframe is key to disrupting potential scams before they inflict widespread harm.

Overcoming Takedown Challenges

Executing efficient domain takedowns requires overcoming significant hurdles. Among the biggest obstacles are “bulletproof” hosting providers that ignore malicious content hosting. These providers, often located in jurisdictions with less stringent legal frameworks, often ignore takedown requests, allowing cybercriminals to thrive and proliferate fraudulent campaigns.

Moreover, some registrars and hosts may reject takedown requests due to insufficient evidence, especially when malicious content is not yet live. Yet, tracking registrant details and correlating them with newly registered domains provides a strategy for overcoming these barriers. However, response delays from takedown submissions are still a major challenge, reflecting the need for a streamlined and responsive approach.

Takedowns: Shielding Against Cyber Threats

Domain takedowns are indispensable in disrupting adversaries and reducing cybercrime. While they cannot eradicate cybercrime completely, fostering cooperation among hosting providers, registrars, law enforcement, and cybersecurity analysts can significantly diminish the reach of criminal activities. By incorporating takedowns into their cybersecurity strategy, organizations influence others to bolster their own defenses and contribute to a safer digital environment.

Effective training and a strategic takedown process enable quick removal of malicious domains, preventing potential widespread damage. This collaborative and educated approach enhances the overall effectiveness of takedowns.

AI: Elevating Takedown Capabilities

Artificial Intelligence (AI) is transforming cybersecurity, particularly in enhancing domain takedown operations. AI-driven platforms comprehensively monitor domain activities, rapidly identifying and adapting to potential threats with high accuracy and few false positives. This predictive capability of AI not only automates and prioritizes threat detection but also offers deeper insights into potential cyber threats through advanced analytical techniques.

For organizations focused on minimizing the risks of cybercrime, domain takedowns, supported by AI, are essential. Integrating AI into takedown strategies ensures that organizations can proactively identify and mitigate emerging threats, shifting from a reactive to a proactive stance in cybersecurity.

This tells us that, far from being obsolete, domain takedowns are evolving with technological advancements and becoming more crucial for organizations aiming to secure their digital footprint against sophisticated cyber-attacks.
