Over 100,000 websites fell victim to a recent web supply chain attack through the Polyfill JavaScript library. This incident underscores significant vulnerabilities in third-party script integration across the web. This article covers what Polyfill does, why it’s now a threat, and the steps you should take if your website relies on it.

Polyfill.io helps web developers achieve cross-browser compatibility by automatically managing necessary polyfills. By adding a script tag to their HTML, developers can ensure that features like JavaScript functions, HTML5 elements, and various APIs work across different browsers. Originally developed by Andrew Betts, Polyfill.io injects JavaScript polyfill libraries based on the user agent or other characteristics, streamlining code maintenance.

Data is among the most valuable assets for companies, making it a prime target for malicious actors. Ransomware attacks that seize data and demand a price for its return have become a significant concern for businesses and individuals. According to the Verizon 2024 Data Breach Investigations Report, about one-third of all breaches involved ransomware or another extortion technique. Here’s everything you need to know about ransomware and how to prevent a successful attack.

On July 8th, the Australian Signals Directorate’s Australian Cyber Security Centre (ASD’s ACSC), the United States Cybersecurity and Infrastructure Security Agency (CISA), the United States National Security Agency (NSA), the United States Federal Bureau of Investigation (FBI) along with several international partners issued an urgent advisory outlining a People’s Republic of China (PRC) state-sponsored cyber group targeting Australian and U.S. enterprises.

The landscape of DDoS attacks is constantly evolving. Gone are the days of simple bandwidth floods. Today’s attackers employ sophisticated tactics, making DDoS protection a complex yet crucial undertaking.

Regularly updating the software on your connected devices is essential to keep them secure from cyber-attacks. To maintain security, it is crucial to install software updates that often contain important security patches that fix vulnerabilities that hackers could exploit. Without these updates, your devices could be at risk of being hacked. Keeping software up to date is vital for cybersecurity and performance, ensuring your devices are protected against vulnerabilities and run efficiently.

We’re in an era of connectivity and convenience, but this has also opened the floodgates to a new wave of cyber threats. Among the most insidious and pervasive is credential stuffing, a cyberattack that exploits the human tendency to reuse passwords across multiple online accounts. This threat is more than just a digital inconvenience. Verizon’s 2024 Data Breach Investigations Report reveals that more than 49% of breaches caused by external actors involve stolen credentials.

The MD5 cryptographic hash function was first broken in 2004, when researchers demonstrated the first MD5 collision, namely two different messages X1 and X2 where MD5(X1) = MD5 (X2). Over the years, attacks on MD5 have only continued to improve, getting faster and more effective against real protocols. But despite continuous advancements in cryptography, MD5 has lurked in network protocols for years, and is still playing a critical role in some protocols even today.
