Web Services

T1584.006 · resource-development

Adversaries may compromise access to third-party web services that can be used during targeting. A variety of popular websites exist for legitimate users to register for web-based services, such as GitHub, Twitter, Dropbox, Google, SendGrid, etc. Adversaries may try to take ownership of a legitimate user's access to a web service and use that web service as infrastructure in support of cyber operations.

Such web services can be abused during later stages of the adversary lifecycle, such as during Command and Control (Web Service), Exfiltration Over Web Service, or Phishing. Using common services, such as those offered by Google or Twitter, makes it easier for adversaries to hide in expected noise. By utilizing a web service, particularly when access is stolen from legitimate users, adversaries can make it difficult to physically tie back operations to them.

Additionally, leveraging compromised web-based email services may allow adversaries to leverage the trust associated with legitimate domains.

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.
