In an effort to mitigate a large class of potential cross-site scripting issues in Firefox, Mozilla has blocked execution of all inline scripts and potentially dangerous eval-like functions for built-in "about: pages" that are the gateway to sensitive preferences, settings, and statics of the browser. Firefox browser has 45 such internal locally-hosted about pages , some of which are listed below that you might have noticed or used at some point: about:config — panel to modify Firefox preferences and critical settings. about:downloads — your recent downloads done within Firefox. about:memory — shows the memory usage of Firefox. about:newtab — the default new tab page. about:plugins — lists all your plugins as well as other useful information. about:privatebrowsing — open a new private window. about:networking — displays networking information. To be noted, these changes do not affect how websites from the Internet work on the Firefox browser, but going forwar...

In cybersecurity, the line between a normal update and a serious incident keeps getting thinner. Systems that once felt reliable are now under pressure from constant change. New AI tools, connected devices, and automated systems quietly create more ways in, often faster than security teams can react. This week's stories show how easily a small mistake or hidden service can turn into a real break-in. Behind the headlines, the pattern is clear. Automation is being used against the people who built it. Attackers reuse existing systems instead of building new ones. They move faster than most organizations can patch or respond. From quiet code flaws to malware that changes while it runs, attacks are focusing less on speed and more on staying hidden and in control. If you're protecting anything connected—developer tools, cloud systems, or internal networks—this edition shows where attacks are going next, not where they used to be. ⚡ Threat of the Week Critical Fortinet Flaw Comes Under...

It's easy to think your defenses are solid — until you realize attackers have been inside them the whole time. The latest incidents show that long-term, silent breaches are becoming the norm. The best defense now isn't just patching fast, but watching smarter and staying alert for what you don't expect. Here's a quick look at this week's top threats, new tactics, and security stories shaping the landscape. ⚡ Threat of the Week F5 Exposed to Nation-State Breach — F5 disclosed that unidentified threat actors broke into its systems and stole files containing some of BIG-IP's source code and information related to undisclosed vulnerabilities in the product. The company said it learned of the incident on August 9, 2025, although it's believed that the attackers were in its network for at least 12 months. The attackers are said to have used a malware family called BRICKSTORM, which is attributed to a China-nexus espionage group dubbed UNC5221. GreyNoise said it observed elevat...

The Russian nation-state threat actor known as Secret Blizzard has been observed orchestrating a new cyber espionage campaign targeting foreign embassies located in Moscow by means of an adversary-in-the-middle ( AitM ) attack at the Internet Service Provider (ISP) level and delivering a custom malware dubbed ApolloShadow. "ApolloShadow has the capability to install a trusted root certificate to trick devices into trusting malicious actor-controlled sites, enabling Secret Blizzard to maintain persistence on diplomatic devices, likely for intelligence collection," the Microsoft Threat Intelligence team said in a report shared with The Hacker News. The activity is assessed to be ongoing since at least 2024, with the campaign posing a security risk to diplomatic personnel relying on local ISPs or telecommunications services in Russia. Secret Blizzard (formerly Krypton), affiliated with the Russian Federal Security Service, is also tracked by the broader cybersecurity commu...

If you came across a celebrity sex video on Facebook featuring Jessica Alba or any other celebrity, just avoid clicking it. Another Facebook scam is circulating across the social networking website that attempts to trick Facebook users into clicking on a link for a celebrity sex tape that instead downloads malware onto their computers. Once installed, the malware would force web browsers to display aggressive advertising web pages which include sites with nudity and fake lotteries. The spam campaign was uncovered by researchers at Cyren, who noted that a malicious Google Chrome extension is spreading nude celebrity PDFs through private messages and posts on various Facebook groups. If opened, the PDF file takes victims to a web page with an image containing a play button, tricking users that the PDF may contain a video. Once clicked, the link redirects users of Internet Explorer, Firefox, or Safari to a web page with overly-aggressive popups and advertisements related to ...

Cybersecurity researchers discover a critical flaw in the popular Evernote Chrome extension that could have allowed hackers to hijack your browser and steal sensitive information from any website you accessed. Evernote is a popular service that helps people taking notes and organize their to-do task lists, and over 4,610,000 users have been using its Evernote Web Clipper Extension for Chrome browser. Discovered by Guardio, the vulnerability ( CVE-2019-12592 ) resided in the ways Evernote Web Clipper extension interacts with websites, iframes and inject scripts, eventually breaking the browser's same-origin policy (SOP) and domain-isolation mechanisms. According to researchers, the vulnerability could allow an attacker-controlled website to execute arbitrary code on the browser in the context of other domains on behalf of users, leading to a Universal Cross-site Scripting (UXSS or Universal XSS) issue. "A full exploit that would allow loading a remote hacker contr...
