Cybercriminals are increasingly targeting DocuSign, the widely used electronic signature
platform, to carry out advanced phishing campaigns aimed at stealing corporate credentials and sensitive data.
With 1.6 million customers globally, including 95% of Fortune 500 companies and over one billion users, DocuSign has become a prime target for attackers who exploit the brand’s trusted reputation.
These attacks reflect a major shift in social engineering tactics. Cybercriminals now use spoofed DocuSign emails, often with familiar branding and yellow “review document” buttons, to trick users. The emails appear authentic, making them difficult to detect through standard security awareness measures.
According to Welivesecurity, phishing is now the initial access point in 19% of data breaches. About 60% of those breaches involve human error, which increases the effectiveness of DocuSign impersonation. The impact can go far beyond stolen credentials, giving attackers entry into networks where they can escalate privileges, move laterally, steal data, or deploy ransomware.
Recent incidents show just how sophisticated these campaigns have become. In some cases, attackers register real DocuSign accounts and use the platform’s APIs to send convincing phishing emails. This abuse of legitimate infrastructure makes the attacks harder to detect.
The most alarming trend is the use of actual DocuSign systems to spread malicious content. By leveraging authenticated channels, attackers can send messages that appear completely legitimate. This makes it difficult for security tools to distinguish between safe and harmful communications.
Some attacks also include QR codes within DocuSign attachments. Victims scan the codes using mobile devices that often lack strong security protections, further increasing the risk.
This evolution in phishing tactics underscores the need for heightened vigilance and improved security practices, especially when interacting with trusted platforms like DocuSign.
