The Impersonation Game: Safeguarding Against Email Attacks

In today’s digital landscape, email remains one of the most commonly used communication channels for both personal and professional purposes. However, this widespread reliance on email also makes it an attractive target for cybercriminals. Email impersonation attacks have become increasingly prevalent, posing significant risks to individuals and organizations alike. In this blog post, we will delve into the intricacies of email impersonation attacks, explore the various techniques employed by attackers, and discuss effective strategies to detect and prevent such threats.


The Anatomy of Email Impersonation Attacks:

Email impersonation attacks involve malicious actors masquerading as legitimate individuals or organizations to deceive recipients and manipulate them into performing specific actions. These attacks can take several forms, including:


  1. CEO/Executive Impersonation: Attackers impersonate high-level executives to request sensitive information or authorize financial transactions. They exploit the authority and credibility associated with executive positions to deceive employees.
  2. Vendor/Supplier Impersonation: Attackers pose as trusted vendors or suppliers, sending fraudulent invoices or payment requests. They take advantage of established relationships and transactional processes to trick organizations into making payments to the wrong accounts.
  3. Brand Impersonation: Attackers mimic well-known brands or companies to gain trust and deceive recipients. They often send fake promotional emails, account verification requests, or alerts, aiming to obtain personal information or login credentials.

Techniques Leveraged by Attackers:

Email impersonation attacks employ several techniques to deceive recipients. Understanding these techniques is crucial for effectively combating such threats:

  • Social Engineering: Attackers exploit psychological manipulation to trick recipients into taking action. This can involve creating a sense of urgency, appealing to authority, or exploiting trust and familiarity.
  • Spoofing: Attackers manipulate email headers to falsify the source of an email, making it appear as if it originated from a legitimate sender.
  • Email Content Manipulation: Attackers carefully craft emails, often mimicking the writing style, tone, and formatting of legitimate communications to increase their chances of success.

Detection Strategies:

Detecting email impersonation attacks can be challenging, as attackers continuously adapt their tactics. However, implementing the following strategies can significantly enhance your ability to identify and prevent these threats:

  • Anti-spam, anti-virus and anti-phishing detection: Inbound and outbound email filtering to block unwanted email.
  • Phishing impersonation protection: Comparing the display name of inbound emails to commonly abused cloud service brand names and VIPs within the organization, analyzing look-a-like domains to identify similar domain names, and taking actions such as blocking, quarantining, tagging with warning subject lines, or adding banners with direct links to the user-level block list for suspicious messages.
  • Email Encryption (TLS,S/MIME, Push-based): Scanning message bodies and attachments for sensitive data.
  • Header anomaly checks: Header anomaly detection identifies if the sender display name is the same as an internal user name.
  • Allow/Block lists: Restricting messages to or from specific email addresses, IP addresses and domains.
