Immediate Actions

 

If you suspect your Gmail business data has been stolen after a phishing attack, act fast to limit further damage:

• Change Passwords Immediately: Update passwords for the compromised account and any linked accounts using a strong, unique passphrase.
• Revoke Suspicious Access: Check account activity and remove any unauthorized third-party access.
• Disconnect Compromised Devices: Isolate any device that may have been used during the attack to prevent further data leakage.
• Notify IT/Security Teams: Inform your organization’s IT department or cybersecurity team without delay.

 

Detailed Recommendations

 

When addressing a cybersecurity incident related to Gmail business data, consider these practical steps to support internal investigation and recovery:

• Review Account Activity: Audit your account’s recent activity logs to identify unusual sign-in patterns or unauthorized actions. Look for IP addresses or locations that do not match your staff's typical behavior.
• Enable Multi-Factor Authentication (MFA): Ensure MFA is active for all business email accounts. This simple step adds another layer of protection even if passwords are compromised.
• Update Security Policies: Review and enhance your cybersecurity policies to protect against future attacks. Include routine phishing awareness training for employees.
• Implement Continuous Monitoring: Use email security tools that offer real-time monitoring and alert features to detect abnormal behavior. This proactive approach can catch breaches early.
• Check for Data Exfiltration: Look for signs that data may have been exported or forwarded to unauthorized recipients. Monitor your email forwarding rules, filters, and any connected applications.
• Conduct a Comprehensive Security Audit: Utilize internal or third-party resources to scan your network and email systems for vulnerabilities and indicators of compromise.
