Several months ago, we disclosed that Pawn Storm was using a then-undiscovered zero-day Java vulnerability to carry out its attacks. At the time, we noted that a separate vulnerability was used to bypass the click-to-play protection that is in use by Java. This second vulnerability has now been patched by Oracle as part of its regular quarterly update.

Click-to-play requires the user to click the space where the Java app would normally be displayed before it is executed. In effect, it asks the user if they are really sure they want to run any Java code.

Bypassing click-to-play protection allows for malicious Java code to run without any alert windows being shown. This was quite useful in Pawn Storm, as it used exploits targeting these vulnerabilities to carry out targeted attacks against North Atlantic Treaty Organization (NATO) members and the White House earlier this year.

Security Predictions for 2020

  • Cybersecurity in 2020 will be viewed through many lenses — from differing attacker motivations and cybercriminal arsenal to technological developments and global threat intelligence — only so defenders can keep up with the broad range of threats.

Business Process Compromise

  • Attackers are starting to invest in long-term operations that target specific processes enterprises rely on. They scout for vulnerable practices, susceptible systems and operational loopholes that they can leverage or abuse. To learn more, read our Security 101: Business Process Compromise.
