3rd Party Script Attack

What Is A 3rd Party Script Attack?

A 3rd party script attack is a form of a cyberattack that originates through third party vendors that websites use to increase performance and mobility on their site. By way of these third party vendors, cyber criminals can easily infiltrate the vulnerabilities through the applications and gain access to the company’s sensitive information as well as the entirety of their customer database. While these apps can provide your website with services of efficiency, higher engagement, and overall impeccable performance, there are a lot of risks that companies must also taken into consideration.

How Do 3rd Party Script Attacks Occur?

When companies use third party applications for their site, the third party vendors then import their scripts that allow them to have access to parts of the websites code. These applications can be anything that enhances a website; a widget, advertisements, or even analytics. All of these applications are designed to further develop your site to be an engaging and interactive space to be, which is exactly why these are the perfect places to launch a cyberattack. These scripts are the hotbeds where cyberattacks occur the most and worst of all, not leave a trace for the business or the customers to detect. As third party vendors use JavaScript code to provide their services to these small and medium sized businesses, cybercriminals have begun to get increasingly familiar with their approach. Apparently, these criminals have realized the level of reliance that these third party vendors give to JavaScript and so have found vulnerabilities within their code to then hijack. Unfortunately these forms of attacks are now growing at a rapid speed. 

Who’s A Target For 3rd Party Script Attacks?

The victims of 3rd party script attacks can vary but essentially, if your business accepts online payments and uses third party applications in any format, you are subject to a 3rd party script attack. If you have a smaller business with an online store and you use multiple third party applications to increase advertising, implement engaging content or analyze information about your visitors, then you may be even more susceptible to a cyberattack. What’s even more complicated to understand is that cybercriminals don’t necessarily need to attack your website first. The vulnerabilities that exist among these third party applications are enough for them to infiltrate and then find other users who have used that same code for another site. This means that the third party vendors can essentially lead the cybercriminals to your site to continue infiltrating and eventually hack. 

Ways 3rd Party Script Attacks Can Reach Your Website 

Hacking Third Party Vendors: One of the most direct ways in which your business can be attacked is through hacks that cybercriminals make towards the same third party applications that you use. As mentioned above, all it takes for hackers is to follow that same piece of code and track down the companies that have imported the application. 

Cybercriminals Posed as Third Party Vendors: Another common method of gaining access to a site’s sensitive information is by hackers duping businesses and posing as third party applications themselves. These sophisticated hackers trick companies by posing as popular applications to improve a site’s interface and overall popularity all the while carrying out a malicious intent to hack. They’ll find top vendors and mimic after their design, aesthetic and so on to appear legitimate enough so that users will download their applications and unfortunately connect them with the most vital and private information of their business.

Inserting False Patches: A common method of gaining access by way of third party vendors is through patches for their applications. Cloaked as a real patch, a cybercriminal can essentially develop a patch and find a means for that patch to be available for the company to use as an update when in reality the hackers have just found a direct way to access all the information they seek. 

Tips To Protect Your Business Against 3rd Party Script Attacks

Hire Designated Site Reliability Engineers (SREs): These engineers will be responsible to keep a close and thorough inventory of all third party applications that’s running on your website. They will be the monitors to closely detect any code unknown. 

Use Trusted Third Party Applications: It’s extremely important to verify all of the applications that have been implemented and associated with your website. Only use trusted vendors who are preferably briefed on security issues such as 3rd party script attacks. 

An Updated Security: This can be a commonly overlooked part of enhancing your protection but verify that your security system is strong and functioning and is frequently updated. More often than not, updated systems can include specific measures that prevent 3rd party script attacks from occurring.
