ATT&CK Technique

Link Target

T1608.005 · resource-development

Adversaries may put in place resources that are referenced by a link that can be used during targeting. An adversary may rely upon a user clicking a malicious link in order to divulge information (including credentials) or to gain execution, as in Malicious Link. Links can be used for spearphishing, such as sending an email accompanied by social engineering text to coax the user to actively click or copy and paste a URL into a browser.

Prior to a phish for information (as in Spearphishing Link) or a phish to gain initial access to a system (as in Spearphishing Link), an adversary must set up the resources for a link target for the spearphishing link. Typically, the resources for a link target will be an HTML page that may include some client-side script such as JavaScript to decide what content to serve to the user. Adversaries may clone legitimate sites to serve as the link target, this can include cloning of login pages of legitimate web services or organization login pages in an effort to harvest credentials during Spearphishing Link.

Adversaries may also Upload Malware and have the link target point to malware for download/execution by the user. Adversaries may purchase domains similar to legitimate domains (ex: homoglyphs, typosquatting, different top-level domain, etc.) during acquisition of infrastructure (Domains) to help facilitate Malicious Link. Links can be written by adversaries to mask the true destination in order to deceive victims by abusing the URL schema and increasing the effectiveness of phishing.

Adversaries may also use free or paid accounts on link shortening services and Platform-as-a-Service providers to host link targets while taking advantage of the widely trusted domains of those providers to avoid being blocked while redirecting victims to malicious pages. In addition, adversaries may serve a variety of malicious links through uniquely generated URIs/URLs (including one-time, single use links). Finally, adversaries may take advantage of the decentralized nature of the InterPlanetary File System (IPFS) to host link targets that are difficult to remove.

Likely Attack Path

Techniques the same actors pair with this one distinctively - those showing up among actors who use this technique noticeably more than across all actors (lift > 1.15), grouped by kill-chain phase. The × is that lift multiplier; the shared-actor count is in the tooltip. A near-universal technique pairs with everything at baseline, so its list is short by design.

Mitigations

1
MITRE ATT&CK mitigations - vendor-agnostic guidance for reducing exposure to this technique.
M1056Pre-compromise

Pre-compromise mitigations involve proactive measures and defenses implemented to prevent adversaries from successfully identifying and exploiting weaknesses during the Reconnaissance and Resource Development phases of an attack. These activities focus on reducing an organization's attack surface, identify adversarial preparation efforts, and increase the difficulty for attackers to conduct successful operations.

Limit Information Exposure
  • Regularly audit and sanitize publicly available data, including job posts, websites, and social media.
  • Use tools like OSINT monitoring platforms (e.g., SpiderFoot, Recon-ng) to identify leaked information.
Protect Domain and DNS Infrastructure
  • Enable DNSSEC and use WHOIS privacy protection.
  • Monitor for domain hijacking or lookalike domains using services like RiskIQ or DomainTools.
External Monitoring
  • Use tools like Shodan, Censys to monitor your external attack surface.
  • Deploy external vulnerability scanners to proactively address weaknesses.
Threat Intelligence
  • Leverage platforms like MISP, Recorded Future, or Anomali to track adversarial infrastructure, tools, and activity.
Content and Email Protections
  • Use email security solutions like Proofpoint, Microsoft Defender for Office 365, or Mimecast.
  • Enforce SPF/DKIM/DMARC policies to protect against email spoofing.
Training and Awareness
  • Educate employees on identifying phishing attempts, securing their social media, and avoiding information leaks.
