The Scale of Email Communication in the US

Legitimate Emails Sent Daily

Globally, it is estimated that around 300 billion emails are sent each day. In the United States, approximately 50–60 billion emails flow through inboxes daily. While many of these messages are vital for day-to-day operations, they also serve as the battleground for phishing emails targeting both individual users and organizations.

Attachments: Essential Yet Risky

In the corporate environment, approximately 25% of legitimate emails include attachments such as reports, invoices, or images according to progress. These files are essential for productivity but also represent a potential vulnerability in computer security when exploited by phishing tactics.

When Attachments Turn Malicious

Although only an estimated 0.1% of all email attachments are malicious, the sheer volume of daily emails means that millions of harmful files circulate every day. Cybercriminals design phishing emails to deliver these dangerous attachments by disguising them as routine documents, PDFs, voicemails, or even e-faxes. Once opened, these files can undermine your cybersecurity and network security.

What’s Hiding Inside Malicious Attachments?

A harmful file attached to an email can cause a variety of problems for your computer.

Sneaky Software Installers

Some attachments can secretly install harmful programs like viruses, spyware, or ransomware. These unwanted programs may steal your personal data or even lock you out of your system, causing major headaches.

Hidden Instructions in Documents

Files such as Microsoft Word or Excel documents might include hidden instructions (known as macros) that run automatically when opened. If you enable these, they could perform actions that damage your computer or expose it to further risks.

Exploiting Software Weaknesses

Certain PDFs or other file types are designed to take advantage of flaws in your software. This can allow hackers to break into your computer without your permission, putting your sensitive information at risk.

Social Engineering Tactics

Often, the attachment is just the first step in a broader attack strategy. The email itself may coax recipients into performing actions that further weaken network security and overall cybersecurity defenses. A well-designed phishing email can trick users into clicking dangerous links. For instance, an example of a phishing email might masquerade as a routine business memo concealing a harmful attachment, and numerous examples of phishing email illustrate how attackers manipulate everyday communications to gain unauthorized access.
