Threat Intelligence: JavaScript Supply Chain Attack Alert: Polyfill.js Compromise

July 3, 2024

We’re reaching out today to alert you to a significant JavaScript supply chain attack that may have impacted millions of legitimate websites. According to our research, tens of millions of websites, accounting for about 4% of the web, use Polyfill.js, an open-source library designed to improve compatibility with older browsers by embedding JavaScript code.

The Threat

Earlier this year, a Chinese company named Funnull acquired the domain and the GitHub account associated with Polyfill.js. Following this acquisition, they modified the Polyfill.js code to insert malicious code into websites. Any script adopted from cdn.polyfill.io was susceptible to downloading malicious code from Funnull’s site.

Response from Major Players

Cloudflare, Google, and even the Polyfill.io domain provider have taken steps to prevent sites with the malicious “plugin” from loading. Despite these measures, the attacks continue to persist. It is highly recommended that websites using these scripts remove them immediately to prevent further exploitation.

Quick Points

  • Scope of Attack: JavaScript supply chain attacks via Polyfill.io have affected tens of millions of legitimate websites, as stated by Cloudflare’s CEO, Matthew Prince.
  • Nature of the Attack: Websites using the compromised script have been turned into “watering-holes” for Chinese cyber-attackers, redirecting users to scam sites or malware.
  • Affected Entities: Major websites such as Hulu, Intuit, Nintendo, JSTOR, and the World Economic Forum have been affected.
  • Preventive Actions: Cloudflare and Google are starting to restrict sites using these malicious scripts.

Immediate Actions

  • Review and Remove: Assess your websites for any dependency on Polyfill.io and remove the scripts as necessary.
  • Monitor Activities: Keep an eye on unusual activities or signs of malicious code.
  • Use Clean Versions: Utilize Fastly or Cloudflare’s “clean” versions of Polyfill scripts when necessary.

Pentest Report Findings

In your next penetration test, look for these report findings:

  • Under the “External IP Vulnerability Analysis Log” and “Internal Vulnerability Analysis Log,” you will find Polyfill-related findings listed under the “Web Application Scanning Consolidation / Info Reporting” section.

Stay Secure

As always, we are dedicated to your security. Take these steps promptly to safeguard your digital assets from this ongoing threat.

How Cybercriminals Use AI to Power Their Attacks

July 2, 2024

Managing a business on your own is challenging enough without worrying about cyberattacks. However, there is cause for alarm as hackers are using artificial intelligence (AI) to launch sophisticated cyberattacks to steal your data and disrupt business operations.

The good news is there are steps you can take to protect your business. This blog will explain how AI is being used in cybercrime and how you can safeguard your business.

How hackers use AI

Here are some of the ways cybercriminals are exploiting AI:

Deepfakes: Hackers use AI to create highly realistic fake videos or audio recordings to impersonate someone you know, like your boss or a trusted friend. These deepfakes can be used to trick you into sending money or sharing sensitive information.

How to spot it: Closely look for details like unnatural facial movements or sloppy voice synchronization.

AI-powered password cracking: With the help of AI, cybercriminals can effortlessly crack common and easy passwords. Hackers with access to advanced computation offered by AI can automate the breaching process, so they can try millions of combinations to guess your password.

How to fight back: Always use unique passwords. Consider using a password manager.

AI-assisted hacking: Hackers no longer have to spend hours looking for vulnerabilities. Instead, with the help of AI, they can create automated programs that not only identify weaknesses in your system but also create new types of malware.

How to stay ahead: Keep your security systems and software updated. Also, a mandate should be set up to scan for vulnerabilities routinely.

Supply chain attacks: Threat actors use AI to insert malicious code into legitimate vendor products, which eventually will compromise your system as well. 

How to protect yourself: Only download software from trusted sources. Always be vigilant with updates and patches.

Boost your defenses

AI-powered cybercrime is a growing threat. That’s why having a strong IT partner by your side can be the ultimate weapon in your arsenal. Partner with us to leverage advanced technology to fortify your defenses.

Don’t Forget Cybersecurity in Your Emergency Preparedness Plan

Posted: June 18, 2024

A disaster preparedness plan helps businesses withstand any calamity. However, many businesses are unaware that a cybersecurity strategy is also crucial for building a robust disaster preparedness plan.

By incorporating cybersecurity into your emergency preparedness plan, you can better protect your business during critical incidents and minimize the impact of cyberthreats. This will help you enhance your business’s resilience, ensuring you’re better equipped to function in the face of unexpected challenges.

Best practices for effective disaster preparedness planning in IT security

Here are some practical tips for improving your organization’s disaster preparedness planning:

1. Protect your IT infrastructure and data

Your data is a gold mine for cybercriminals, and they’ll do anything to get their hands on it. That’s why it’s important to strengthen your IT infrastructure to withstand any disaster. Failing to implement adequate measures to protect your data could also attract fines and lawsuits.

Pro tip:

  • Firewalls, intrusion detection systems and encryptions can strengthen your IT security.
  • Implementing a process to fix and update software patches regularly will help you avoid security vulnerabilities.

2. Back up critical data

Data loss can occur for many reasons, including cyberattacks and natural disasters. If your organization has not correctly backed up its data, recovery can be costly, time-consuming and seemingly impossible. If you want your business to survive, your disaster preparedness plan must ensure that your data remains clean, available and restorable.

Pro tip:

  • Regularly back up critical data.
  • Back up your data off-site or in the cloud.
  • Test backups regularly to verify their integrity.

3. Improve employee awareness

Your employees are your weakest link only if they don’t have proper training. By conducting regular security awareness training, you can improve their knowledge. It also increases your employees’ ability and willingness to follow security protocols during an emergency.

Pro tip:

  • Train your employees to identify phishing attempts, report suspicious activities and follow security protocols.
  • Promote a culture of preparedness.
  • Routinely test employee preparedness through simulated scenarios or drills.

4. Review insurance policies

Insurance plays a critical role in promoting disaster resilience. It can help speed up your recovery after an incident. It’s a good idea to have property insurance, business interruption insurance and cybersecurity insurance to cover all bases.

Pro tip:

  • Routinely review insurance policies to ensure you have proper coverage for potential risks and disasters.
  • Maintain records of your assets, inventory and financial transactions to facilitate insurance claims and recovery efforts.
  • Take the help of an insurance expert to understand current coverage and determine if additional coverage is required.

5. Evaluate vendor and supplier preparedness

Disasters come unannounced and any weak link in your supply chain will only increase your vulnerability. Knowing if your vendor has a disaster preparedness plan is crucial for protecting your customers and overall business operations.

Pro tip:

  • Ensure your vendors’ or suppliers’ disaster preparedness practices align with your plans.
  • Ask your vendor to share their disaster communication plan with you.
  • Recommend that your suppliers test their disaster plan at least once a year.
  • Ask them to take the help of an experienced IT service provider if you think their plan is lacking.

6. Review and revise your preparedness strategies

It’s essential to test your preparedness plan for weaknesses and shortcomings regularly. By testing, you can fix the gaps and strengthen your strategy. A thoroughly tested plan will protect your data and help you avoid revenue loss during an outage, cyberattack or natural disaster.

Pro tip:

  • Extensively document changes in the organization, including people, processes and resources.
  • Conduct mock tests to gauge the preparedness of your plan and employees.
  • Take the help of an IT service provider to enhance your plan. They can also carry out timely audits to test the effectiveness of your program.

We can help you outlast any disaster

It can be challenging to build a comprehensive disaster preparedness plan that is robust and includes a thorough cybersecurity strategy on your own. By partnering with an experienced IT service provider like us, your business can become resilient and outlast any disaster.
