Think your WAF has you covered? Think again. This holiday season, unmonitored JavaScript is a critical oversight allowing attackers to steal payment data while your WAF and intrusion detection systems see nothing. With the 2025 shopping season weeks away, visibility gaps must close now. Get the complete Holiday Season Security Playbook here . Bottom Line Up Front The 2024 holiday season saw major attacks on website code: the Polyfill.io breach hit 500,000+ websites, and September's Cisco Magecart attack targeted holiday shoppers. These attacks exploited third-party code and online store weaknesses during peak shopping, when attacks jumped 690% . For 2025: What security steps and monitoring should online retailers take now to prevent similar attacks while still using the third-party tools they need? As holiday shopping traffic increases, companies strengthen their servers and networks, but a critical weak spot remains unwatched: the browser environment where malicious code r...

A team of German cybersecurity researchers has discovered a new cache poisoning attack against web caching systems that could be used by an attacker to force a targeted website into delivering error pages to most of its visitors instead of legitimate content or resources. The issue could affect sites running behind reverse proxy cache systems like Varnish and some widely-used Content Distribution Networks (CDNs) services, including Amazon CloudFront, Cloudflare, Fastly, Akamai, and CDN77. In brief, a Content Distribution Network (CDN) is a geographically distributed group of servers that sit between the origin server of a website and its visitors to optimize the performance of the website. A CDN service simply stores/caches static files—including HTML pages, JavaScript files, stylesheets, images, and videos—from the origin server and delivers them to visitors more quickly without going back to the originating server again and again. Each of the geographically distributed CDN se...

As part of  Checkmarx's mission  to help organizations develop and deploy secure software, the Security Research team started looking at the security posture of major car manufacturers. Porsche has a well-established Vulnerability Reporting Policy (Disclosure Policy) [1] , it was considered in scope for our research, so we decided to start there, and see what we could find. What we found is an attack scenario that results from chaining security issues found on different Porsche's assets, a website and a GraphQL API, that could lead to data exfiltration. Data exfiltration is an attack technique that can impact businesses and organizations, regardless of size. When malicious users breach a company's or organization's systems and exfiltrate data, it can be a jarring and business-critical moment. Porsche has a diverse online presence - deploying several microsites, websites, and web applications. The Porsche Experience [2] is one website that allows registered users to ...

Explore how relying on CSRF tokens as a security measure against CSRF attacks is a recommended best practice, but in some cases, they are simply not enough. Introduction As per the Open Web Application Security Project (OWASP), CSRF vulnerabilities are recognized as a significant threat and are historically part of their top risks. The implications of CSRF attacks are far-reaching and could lead to critical security implications, such as: Unauthorized actions : Attackers can trick users into executing unwanted actions on websites where they're authenticated. For example, changing account settings, making purchases, or transferring funds. Identity exploitation : The attack works by exploiting the victim's authenticated session, making the application unable to distinguish between legitimate user requests and forged ones. Silent execution : CSRF attacks often happen without the victim's knowledge as they can be hidden in seemingly innocent links, images, or embedded c...

In cybersecurity, precision matters—and there’s little room for error. A small mistake, missed setting, or quiet misconfiguration can quickly lead to much bigger problems. The signs we’re seeing this week highlight deeper issues behind what might look like routine incidents: outdated tools, slow response to risks, and the ongoing gap between compliance and real security. For anyone responsible for protecting systems, the key isn’t just reacting to alerts—it’s recognizing the larger patterns and hidden weak spots they reveal. Here’s a breakdown of what’s unfolding across the cybersecurity world this week. ⚡ Threat of the Week NCA Arrests for Alleged Scattered Spider Members — The U.K. National Crime Agency (NCA) announced that four people have been arrested in connection with cyber attacks targeting major retailers Marks & Spencer, Co-op, and Harrods.

A security researcher has discovered an interesting loophole in Gmail Android app that lets anyone send an email that looks like it was sent by someone else, potentially opening doors for Phishers. This is something that we call E-mail Spoofing – the forgery of an e-mail header so that the email appears to have originated from someone other than the actual source. Generally, to spoof email addresses, an attacker needs: A working SMTP (Simple Mail Transfer Protocol) server to send email A M ailing Software However, an independent security researcher, Yan Zhu , discovered a similar bug in official Gmail Android app that allowed her to hide her real email address and change her display name in the account settings so that the receiver will not be able to know the actual sender. How to Send Spoofed Emails via Gmail Android App? To demonstrate her finding, Zhu sent an email to someone by changing her display name to yan ""security@google.com" (w...

Newly discovered security vulnerabilities in ADT's Blue (formerly LifeShield) home security cameras could have been exploited to hijack both audio and video streams. The  vulnerabilities  (tracked as CVE-2020-8101) were identified in the video doorbell camera by Bitdefender researchers in February 2020 before they were eventually addressed on August 17, 2020. LifeShield was acquired by Florida-based ADT Inc. in 2019, with Lifeshield's DIY home security solutions rebranded as Blue as of January 2020. The company's products had a 33.6% market share in the U.S. last year. The security issues in the doorbell camera allow an attacker to Obtain the administrator password of the camera by simply knowing its MAC address, which is used to identify a device uniquely Inject commands locally to gain root access, and Access audio and video feeds using an unprotected  RTSP  (Real-Time Streaming Protocol) server The doorbell is designed to periodically send heartbeat mes...

New research has found that the CONTINUATION frame in the HTTP/2 protocol can be exploited to conduct denial-of-service (DoS) attacks. The technique has been codenamed  HTTP/2 CONTINUATION Flood  by security researcher Bartek Nowotarski, who reported the issue to the CERT Coordination Center (CERT/CC) on January 25, 2024. "Many HTTP/2 implementations do not properly limit or sanitize the amount of CONTINUATION frames sent within a single stream," CERT/CC  said  in an advisory on April 3, 2024. "An attacker that can send packets to a target server can send a stream of CONTINUATION frames that will not be appended to the header list in memory but will still be processed and decoded by the server or will be appended to the header list, causing an out of memory (OOM) crash." Like in HTTP/1, HTTP/2 uses header fields within requests and responses. These  header fields  can comprise header lists, which in turn, are serialized and broken into  header blo...

Researchers reported on Monday that hackers are now exploiting Google's Analytics service to stealthily pilfer credit card information from infected e-commerce sites. According to several independent reports from PerimeterX , Kaspersky , and Sansec , threat actors are now injecting data-stealing code on the compromised websites in combination with tracking code generated by Google Analytics for their own account, letting them exfiltrate payment information entered by users even in conditions where content security policies are enforced for maximum web security. "Attackers injected malicious code into sites, which collected all the data entered by users and then sent it via Analytics," Kaspersky said in a report published yesterday. "As a result, the attackers could access the stolen data in their Google Analytics account." The cybersecurity firm said it found about two dozen infected websites across Europe and North and South America that specialized in...

Today, most Network Detection and Response (NDR) solutions rely on traffic mirroring and Deep Packet Inspection (DPI). Traffic mirroring is typically deployed on a single-core switch to provide a copy of the network traffic to a sensor that uses DPI to thoroughly analyze the payload. While this approach provides detailed analysis, it requires large amounts of processing power and is blind when it comes to encrypted network traffic. Metadata Analysis has been specifically developed to overcome these limitations. By utilizing metadata for analysis, network communications can be observed at any collection point and be enriched by the information providing insights about encrypted communication. Network Detection and Response (NDR) solutions have become crucial to reliably monitor and protect network operations. However, as network traffic becomes encrypted and data volumes continue to increase, most traditional NDR solutions are reaching their limits. This begs the question: What detect...

If you think that the HTTP/2 protocol is more secure than the standard HTTP ( Hypertext Transfer Protocol ), then you might be wrong, as it took researchers just four months to discover four flaws in the HTTP/2 protocol. HTTP/2 was launched properly just in May last year after Google bundled its SPDY project into HTTP/2 in February in an effort to speed up the loading of web pages as well as the browsing experience of the online users. Now, security researchers from data center security vendor Imperva today at Black Hat conference revealed details on at least four high-profile vulnerabilities in HTTP/2 – a major revision of the HTTP network protocol that the today’s web is based on. The vulnerabilities allow attackers to slow web servers by flooding them with innocent looking messages that carry a payload of gigabytes of data, putting the servers into infinite loops and even causing them to crash. The HTTP/2 protocol can be divided into three layers: The transmissio...
