March 2025 Cybersecurity Roundup

Protecting your organization from ransomware like Medusa starts with securing employee communication and strengthening internal cyber hygiene. 

• Enforce two-factor authentication on all email, VPN, and cloud-based accounts to reduce unauthorized access points. 

• Train employees to recognize phishing attempts, especially lookalike email addresses and emotional manipulation tactics. 

• Establish clear incident reporting protocols to ensure IT teams can act during critical early stages of an intrusion. 

SSL.com’s S/MIME certificates help defend against phishing-based ransomware by enabling organizations to digitally sign and encrypt emails, ensuring recipients can verify the sender’s identity and content integrity. 

Preventing sophisticated crypto heists starts with securing access to critical systems and trusted third-party integrations. 

• Require strong authentication measures for employees and partners accessing wallets, APIs, and financial tools. 

• Vet and continuously monitor supplier systems with direct access to sensitive infrastructure. 

• Implement least-privilege access controls and log all system interactions for audit and incident response. 

SSL.com’s Client Authentication certificates protect an organization’s critical systems by verifying user identities beyond passwords, ensuring only trusted individuals can access high-value data. These certificates can also support secure SSO across internal systems. 

Responding quickly to credential exposure and potential breaches is key to minimizing damage and meeting compliance standards. 

• Immediately reset all user and admin credentials across SSO, LDAP, and encrypted configuration files. 

• Enforce multi-factor authentication (MFA) and monitor for suspicious activity, especially across cloud login systems. 
• Audit and revoke inactive accounts, and rotate all cryptographic keys and secrets regularly.

To address this active threat and improve resilience against similar exploits, prioritize the following: 

• Deploy April 2025 Microsoft patches immediately to fix CVE-2025-29824. 
• Update endpoint security to detect and block related malware threats. 
• Implement robust PAM and review user account permissions regularly.

Major cloud acquisitions highlight the rising urgency of robust, scalable cybersecurity in multi-cloud environments. 

• Regularly evaluate and strengthen cloud security posture as platforms consolidate and evolve. 
• Prioritize identity verification, encryption, and certificate management to protect cross-cloud communications. 
• Ensure vendor-agnostic security solutions that integrate easily across Google, AWS, Azure, and private infrastructure.
