Stopping Zero-Click Email Attacks

Stopping Zero-Click Email Attacks

Zero-day attacks remain a global security challenge, even with continued patching and software updates for endpoints, mobile devices, and systems. The hackers develop an exploit against exposed attack surfaces with a known vulnerability while catching clients between patch cycles.

Email security faces a similar attack vector called a “zero-click attack.” This email message attack vector continues to make headlines because the attack does not require user interaction.

This article discusses the challenge of stopping a successful zero-click attack from happening and what solutions are available to help stop these malicious messages from reaching users’ inboxes. Many email security solutions focus on post-delivery protection but have yet to prevent these attacks. Cloud-based email security solutions like Trustifi delivers pre-delivery protection to organizations stopping zero-click attacks.

Zero-Click Attacks Becoming a Big Problem Globally

Zero-click attacks are cyber-attacks that do not require input or human interaction from the target. This method is undetectable, does not rely on social engineering or deceptive tactics, and does not require the user to click on links or download files. Even highly skilled security teams may need help identifying and preventing this attack.

Cyber attacks target a range of high-value targets, including organizations, governments, small businesses, and individuals. State-sponsored attacks often use the zero-click approach to access companies for significant financial gain by selling data or holding ransom for third parties such as contractors, suppliers, and ecosystem partners.

In 2021, Citizen Lab discovered Apple’s messaging apps program as a zero-click iPhone spyware exploit named “FORCEDENTRY.”

The spyware was installed on devices belonging to members of the European Parliament, Saudi officials, legislators, jurists, journalists, and members of civil organizations and their families.

Zero-Click Bypassing Email Security Post-Delivery Protection

Zero-click vulnerability attacks aim to bypass legacy email security, posing a challenge for users to safeguard themselves. Mobile devices used by employees for both personal and work use are a particular concern as they are highly vulnerable to zero-click attacks against their email content.

“A zero-click hack can exploit devices, including the operating system using a data verification loophole vulnerability.”

Most software has a data-verification function and adaptive controls to help prevent cyber breaches exploiting known and unknown software vulnerabilities.

Legacy thinking around email security solutions, secure email gateways (SEG), and post-delivery protection do little to stop a zero-click attack. These older strategies served a purpose when email attacks became dormant. If an email had a malicious link that required user interaction before becoming an exploit attack, these solutions could quarantine and extract the message from the user inboxes.

None of these strategies stop a zero-click attack.
