Adobe Acrobat Sign Phishing Emails Continue to Target Businesses

Adobe Acrobat Sign Phishing Emails Continue to Target Businesses

Security researchers are warning about phishing campaigns that impersonate Adobe Acrobat Sign. These emails claim you have a document waiting for review or signature and are designed to steal login credentials or deliver malware.

Because Adobe Sign is widely used in business environments, these emails often appear normal and trustworthy. Many users are accustomed to receiving contracts, invoices, and shared documents through Adobe services, which makes the phishing attempt more convincing.

How It Works

• You receive an email claiming a document requires your signature or review.
• The email appears to come from Adobe Acrobat Sign.
• The message includes a “Review and Sign” or “Open Document” button.
• The link redirects you to a fake login page or malicious website.
• If you enter your credentials, attackers capture them immediately.

Why It Is Dangerous

• The emails closely resemble legitimate Adobe notifications.
• Fake login pages can look nearly identical to Microsoft 365 sign in screens.
• Stolen credentials can provide attackers access to email, files, and company systems.
• Some attacks also attempt to deliver malware through fake document downloads.
