DoubleClickjacking is a sophisticated form of clickjacking that exploits a double-click sequence to bypass existing security measures. Here's a brief overview of how it works and why it's concerning:
How DoubleClickjacking Works
Initial Setup: The attacker creates a website with a button that opens a new window.
Prompting Double-Click: When the user clicks the button, a new window opens, prompting the user to double-click.
Manipulating Windows: During the double-click sequence, the attacker manipulates the timing and event sequence to replace or close the top-level browser window.
Unauthorized Actions: The second click unknowingly authorizes a malicious action, such as granting access to sensitive information or authorizing a transaction.
Why It's Dangerous
DoubleClickjacking is particularly dangerous because it can bypass modern web browsers' clickjacking protections by exploiting the brief interval between clicks. This makes it difficult to detect and prevent, leaving many online platforms vulnerable
Real-World Impact
Account Takeovers: Attackers can take over user accounts by authorizing malicious applications.
Unauthorized Actions: Users may inadvertently change critical account settings or initiate financial transactions.
Platforms Affected: Major websites relying on OAuth for account authorization, such as Salesforce, Slack, and Shopify, are vulnerable to this attack.
