Threat Intelligence Brief
Curated summary with source attribution
Source: darkreading.com
Threat Risk: High
Victim: Enterprises with privileged internal users
Incident: Ransomware groups are actively recruiting and purchasing access from malicious insiders to bypass security controls.
Impact: High-cost breaches characterized by rapid data exfiltration and widespread encryption of virtual environments.
Attacker: Ransomware groups and malicious insiders
Analysis: Threat actors are increasingly leveraging the Dark Web to recruit insiders who sell legitimate network access to bypass perimeter security. This strategic shift is a direct response to the proliferation of MFA and improved firewall configurations. By gaining internal footholds, attackers can more easily target critical assets like hypervisors and backup systems.
Recommendations: Implement Just-In-Time (JIT) access to limit the duration of elevated privileges.; Enforce separate credentials and strict MFA for backups, hypervisors, and EDR consoles.; Strengthen offboarding protocols to ensure immediate revocation of all access upon employee termination.
