Don’t let imposters into your inbox – Sophos News 1 mes ago

Phishing emails impersonating well-known brands and VIPs within an organization are a big problem for security teams to deal with. So, we’re excited to announce that you’ll now be able to detect and block these impersonation attacks with Sophos Email Advanced.

Email impersonation phishing attacks in action

In our latest study, we found that five out of ten organizations view malicious emails as their top security concern, with 53% experiencing a phishing attack in the past twelve months.

Impersonation attacks are often the hardest to combat, and usually with no malicious payload to detect. In these attacks, criminals regularly try to deceive employees, using the name of a trusted sender to encourage victims to reply, click a link, open an attachment, and so on.

Relying on users to merely scan email sender addresses, these attacks use simple display name forgery to change the visible part of the email address that we see in many common email clients.

Changing the display name to that of a trusted brand or a senior executive within the organization is a simple but effective technique for attackers.

These attacks reign down from free email accounts, and in more targeted attacks, are known to use lookalike domain names, like that of the corporate domain.

The latest highlights

The most recent enhancement for Sophos Email Advanced offers crucial protection against these impersonation phishing attacks as well as several great advancements:

  • Compares the display name of inbound emails to the display name of commonly abused cloud service brand names and to VIPs within the customers organization to check for matches. These could be the CEO, CFO, and HR Director, etc.
  • Provides a simple wizard to identify and add VIPs within the organization to your policy for analysis with all inbound messages.
  • Compares header information, analyzing the display name in relation to the full email address and domain name used, to identify free email domains, lookalike domains of popular cloud services such as Microsoft, Amazon, and VIP name impersonation attempts.

Identifying VIPs

VIPs are employees in the organization who are most likely to be impersonated by phishing attackers.

While all users will receive the same protection, the system will look for external senders impersonating your VIPs, and you can add up to 200 VIPs to the list.

Creating a VIP list in Sophos Central couldn’t be simpler. You can choose to “Add VIPs” by searching your user list for known individuals.

Alternatively, if active directory synchronization has been enabled, select “Help me find VIPs” and Sophos Email will look for users with titles that are in line with job roles most likely to be impersonated:

  • CEO
  • President
  • Chief Financial Officer
  • CFO
  • Finance Director
  • Human Resources Director
  • HR Director

Acting on the threat

This new service allows email administrators to act on potential threats with policy controls to quarantine suspicious messages, tag the subject line, delete them or warn users with a banner added to inbound emails.

The enhanced “At Risk Users” report gives a deeper level of visibility into these phishing threats. It provides a breakdown of phishing impersonation attempts received, as well as any users who have either been warned or blocked from visiting URLs with malicious content. Drill-down levels provide further insight, including:

  • Number of impersonation emails received by user allows you to easily see those most targeted
  • Impersonation type: VIP or brand impersonation
  • Summary information for each phishing email including display name and email address used, and whether the recipient replied
  • Full visibility of email header, message content and attachment types
