Email Server Attacks

Email Exchange Attacks: Protecting Your Organization from Spear Phishing and Email Fraud

Email-based attacks, including spear phishing and social engineering, are increasingly used to steal sensitive user data such as login credentials. Attacks targeting Microsoft environments—both on-site servers and cloud services like Office 365—are on the rise. One common tactic involves attackers impersonating trusted contacts, tricking victims into clicking malicious SharePoint file-sharing links embedded in emails.

Microsoft Office 365 accounts are frequent targets for spear phishing attacks, which often involve email spoofing aimed at specific individuals or organizations to gain unauthorized access to email accounts or shared files.

At Digitpol, our Cyber and Fraud Team consists of certified examiners specializing in email server attacks, scams, and fraud investigations. We deploy expert computer forensic analysts to investigate breaches, identify attack vectors, and deliver detailed reports. Our team works to ensure your network is secure, your user account policies are properly configured, and hackers are removed to prevent future incidents.

Key steps we take during email attack investigations include:

• Forensic analysis of logs using certified tools, reviewing IP addresses and registry entries, including user login events, failed login attempts, changes to inbox rules or policies, and password modifications for all relevant accounts.

• In-depth examination of suspected phishing emails, including email headers and attachments, to trace the source and impact of the attack. We require raw email files (.msg or .eml) for thorough analysis.

• Forensic inspection of compromised devices such as computers, smartphones, and tablets to detect malware or active intrusions.

• Comprehensive server and on-site Microsoft Exchange forensic investigations.
