What is JBOH (JavaScript-Binding-Over-HTTP)?

JavaScript-Binding-Over-HTTP (JBOH) is a mobile device threat directed at Android users. By exploiting a malicious or compromised app, attackers can remotely trigger any code or command for their malicious purposes. These JBOH attacks commonly use apps from lesser-known developers in the Google Play Store, aiming to conceal their malicious intent from users and moderation until the attack is initiated.

How does a JBOH attack happen?

JBOH attacks start with the creation or compromise of an app, which is then uploaded to the Google Play Store. When an unsuspecting user downloads and installs this app on their mobile device, it provides the attacker with the ability to execute any code remotely. The exact nature of the attack can vary, such as snooping on user activities or communications or encrypting data for ransom purposes.

How to prevent a JBOH attack?

To safeguard against JBOH attacks, it’s vital to educate both yourself and your employees. Exercise caution and practice cyber safety measures when downloading mobile applications, mainly if you handle sensitive information on your devices. This includes avoiding downloading apps from unverified developers, prioritizing apps with positive user reviews, and employing endpoint security solutions for enhanced device safety.

While the hackers themselves create some of the apps used in JBOH attacks, many others are legitimate apps that have been compromised. Therefore, app developers must be diligent in identifying and addressing vulnerabilities.

Although JBOH attacks are relatively uncommon, being prepared to defend against them and other cyber threats is a wise long-term investment.


Threat actors can weaponize JBOH to compromise an app on Google Play Store, effective cyber threat intelligence and cyber hygiene is paramount to secure against JBOH attack. In addition, the foundation of creating a secure mobile application depends on knowledge and determination. Developers must invest the effort to educate themselves about the principles of secure app development, as well as familiarize themselves with prevalent vulnerabilities and security flaws that tend to infiltrate applications.

By integrating security seamlessly into their development workflow, be it through conducting meticulous security audits of third-party libraries or employing straightforward techniques like code obfuscation; developers can craft applications that thwart not only potential attackers but also remain resilient in the face of threats.
