Recommended Security Actions
Ransomware attacks are increasingly targeting both enterprise and mid-sized organizations across all sectors. The following steps are critical to reduce impact and prevent future incidents:
- Monitor continuously: Use DeXpose’s dark web and infostealer monitoring platform to detect breached credentials, leaked databases, and threat actor chatter in near real-time—before damage spreads internally.
- Conduct a compromise assessment: Immediately initiate a full incident review to determine how attackers infiltrated your network, what data may have been exfiltrated, and whether any persistence mechanisms remain active.
- Validate your backups: Ensure that your backups are current, encrypted, and stored offline. Utilize immutable backup solutions to defend against ransomware encryption and deletion attempts.
- Apply threat intelligence: Integrate external threat feeds, including DeXpose-provided indicators of compromise (IOCs), into your SIEM or XDR platforms for real-time alerting and correlation.
- Harden employee defenses: Run phishing simulations and enforce multi-factor authentication (MFA) across all access points. Attackers often exploit weak or reused credentials sourced from the dark web.
- Engage professional response teams: Involve cybersecurity incident response experts, threat analysts, and legal counsel before initiating any dialogue with ransomware groups or ransom brokers.
