Hackers Use CAPTCHA Trick on Webflow CDN PDFs to Bypass Security Scanners

Hackers Use CAPTCHA Trick on Webflow CDN PDFs to Bypass Security Scanners

Feb 13, 2025 Web Security / Cloud Security
A widespread phishing campaign has been observed leveraging bogus PDF documents hosted on the Webflow content delivery network (CDN) with an aim to steal credit card information and commit financial fraud. "The attacker targets victims searching for documents on search engines, resulting in access to malicious PDF that contains a CAPTCHA image embedded with a phishing link, leading them to provide sensitive information," Netskope Threat Labs researcher Jan Michael Alcantara said . The activity, ongoing since the second half of 2024, entails users looking for book titles, documents, and charts on search engines like Google to redirect users to PDF files hosted on Webflow CDN. These PDF files come embedded with an image that mimics a CAPTCHA challenge, causing users who click on it to be taken to a phishing page that, this time, hosts a real Cloudflare Turnstile CAPTCHA. In doing so, the attackers aim to lend the process a veneer of legitimacy, fooling victims into think...

Hackers Exploit Google Tag Manager to Deploy Credit Card Skimmers on Magento Stores

Feb 10, 2025 Malware / Payment Security
Threat actors have been observed leveraging Google Tag Manager (GTM) to deliver credit card skimmer malware targeting Magento-based e-commerce websites. Website security company Sucuri said the code, while appearing to be a typical GTM and Google Analytics script used for website analytics and advertising purposes, contains an obfuscated backdoor capable of providing attackers with persistent access. As of writing, as many as three sites have been found to be infected with the GTM identifier (GTM-MLHK2N68) in question, down from six reported by Sucuri. GTM identifier refers to a container that includes the various tracking codes (e.g., Google Analytics, Facebook Pixel) and rules to be triggered when certain conditions are met. Further analysis has revealed that the malware is being loaded from the Magento database table "cms_block.content," with the GTM tag containing an encoded JavaScript payload that acts as a credit card skimmer. "This script was designed to ...

DragonRank Exploits IIS Servers with BadIIS Malware for SEO Fraud and Gambling Redirects

DragonRank Exploits IIS Servers with BadIIS Malware for SEO Fraud and Gambling Redirects

Feb 10, 2025 Malware / Web Security
Threat actors have been observed targeting Internet Information Services (IIS) servers in Asia as part of a search engine optimization (SEO) manipulation campaign designed to install BadIIS malware. "It is likely that the campaign is financially motivated since redirecting users to illegal gambling websites shows that attackers deploy BadIIS for profit," Trend Micro researchers Ted Lee and Lenart Bermejo said in an analysis published last week, Targets of the campaign include IIS servers located in India, Thailand, Vietnam, Philippines, Singapore, Taiwan, South Korea, Japan, and Brazil. These servers are associated with government, universities, technology companies, and telecommunications sectors. Requests to the compromised servers can then be served altered content from attackers, ranging from redirections to gambling sites to connecting to rogue servers that host malware or credential harvesting pages. It's suspected that the activity is the work of a Chinese-s...

Microsoft Identifies 3,000 Leaked ASP.NET Keys Enabling Code Injection Attacks

Microsoft Identifies 3,000 Leaked ASP.NET Keys Enabling Code Injection Attacks

Feb 07, 2025 Cloud Security / Web Security
Microsoft is warning of an insecure practice wherein software developers are incorporating publicly disclosed ASP.NET machine keys from publicly accessible resources, thereby putting their applications in attackers' pathway. The tech giant's threat intelligence team said it observed limited activity in December 2024 that involved an unknown threat actor using a publicly available, static ASP.NET machine key to inject malicious code and deliver the Godzilla post-exploitation framework. It also noted that it has identified over 3,000 publicly disclosed keys that could be used for these types of attacks, which it's calling ViewState code injection attacks . "Whereas many previously known ViewState code injection attacks used compromised or stolen keys that are often sold on dark web forums, these publicly disclosed keys could pose a higher risk because they are available in multiple code repositories and could have been pushed into development code without modificat...

Python-Based Bots Exploiting PHP Servers Fuel Gambling Platform Proliferation

Python-Based Bots Exploiting PHP Servers Fuel Gambling Platform Proliferation

Jan 17, 2025 Web Security / Botnet
Cybersecurity researchers have exposed a new campaign that targets web servers running PHP-based applications to promote gambling platforms in Indonesia. "Over the past two months, a significant volume of attacks from Python-based bots has been observed, suggesting a coordinated effort to exploit thousands of web apps," Imperva researcher Daniel Johnston said in an analysis. "These attacks appear tied to the proliferation of gambling-related sites, potentially as a response to the heightened government scrutiny ." The Thales-owned company said it has detected millions of requests originating from a Python client that includes a command to install GSocket (aka Global Socket), an open-source tool that can be used to establish a communication channel between two machines regardless of the network perimeter. It's worth noting that GSocket has been put to use in many a cryptojacking operation in recent months, not to mention even exploiting the access provi...
WordPress Skimmers Evade Detection by Injecting Themselves into Database Tables

WordPress Skimmers Evade Detection by Injecting Themselves into Database Tables

Jan 13, 2025 Payment Security / Web Security
Cybersecurity researchers are warning of a new stealthy credit card skimmer campaign that targets WordPress e-commerce checkout pages by inserting malicious JavaScript code into a database table associated with the content management system (CMS). "This credit card skimmer malware targeting WordPress websites silently injects malicious JavaScript into database entries to steal sensitive payment details," Sucuri researcher Puja Srivastava said in a new analysis. "The malware activates specifically on checkout pages, either by hijacking existing payment fields or injecting a fake credit card form." The GoDaddy-owned website security company said it discovered the malware embedded into the WordPress wp_options table with the option "widget_block," thus allowing it to avoid detection by scanning tools and persist on compromised sites without attracting attention. In doing so, the idea is to insert the malicious JavaScript into an HTML block widget thr...
New "DoubleClickjacking" Exploit Bypasses Clickjacking Protections on Major Websites

New "DoubleClickjacking" Exploit Bypasses Clickjacking Protections on Major Websites

Jan 01, 2025 Web Security / Vulnerability
Threat hunters have disclosed a new "widespread timing-based vulnerability class" that leverages a double-click sequence to facilitate clickjacking attacks and account takeovers in almost all major websites. The technique has been codenamed DoubleClickjacking by security researcher Paulos Yibelo. "Instead of relying on a single click, it takes advantage of a double-click sequence," Yibelo said . "While it might sound like a small change, it opens the door to new UI manipulation attacks that bypass all known clickjacking protections, including the X-Frame-Options header or a SameSite: Lax/Strict cookie." Clickjacking , also called UI redressing, refers to an attack technique in which users are tricked into clicking on a seemingly innocuous web page element (e.g., a button), leading to the deployment of malware or exfiltration of sensitive data. DoubleClickjacking is a variation of this theme that exploits the gap between the start of a click and the...

Opera Browser Fixes Big Security Hole That Could Have Exposed Your Information

Oct 30, 2024 Browser Security / Vulnerability
A now-patched security flaw in the Opera web browser could have enabled a malicious extension to gain unauthorized, full access to private APIs. The attack, codenamed CrossBarking , could have made it possible to conduct actions such as capturing screenshots, modifying browser settings, and account hijacking, Guardio Labs said. To demonstrate the issue, the company said it managed to publish a seemingly harmless browser extension to the Chrome Web Store that could then exploit the flaw when installed on Opera, making it an instance of a cross-browser-store attack. "This case study not only highlights the perennial clash between productivity and security but also provides a fascinating glimpse into the tactics used by modern threat actors operating just below the radar," Nati Tal, head of Guardio Labs, said in a report shared with The Hacker News. The issue has been addressed by Opera as of September 24, 2024, following responsible disclosure. That said, this is not th...

DragonRank Black Hat SEO Campaign Targeting IIS Servers Across Asia and Europe

DragonRank Black Hat SEO Campaign Targeting IIS Servers Across Asia and Europe

Sep 11, 2024 Network Security / Cyber Espionage
A "simplified Chinese-speaking actor" has been linked to a new campaign that has targeted multiple countries in Asia and Europe with the end goal of performing search engine optimization (SEO) rank manipulation. The black hat SEO cluster has been codenamed DragonRank by Cisco Talos, with victimology footprint scattered across Thailand, India, Korea, Belgium, the Netherlands, and China. "DragonRank exploits targets' web application services to deploy a web shell and utilizes it to collect system information and launch malware such as PlugX and BadIIS, running various credential-harvesting utilities," security researcher Joey Chen said . The attacks have led to compromises of 35 Internet Information Services ( IIS ) servers with the end goal of deploying the BadIIS malware, which was first documented by ESET in August 2021.

DigiCert to Revoke 83,000+ SSL Certificates Due to Domain Validation Oversight

DigiCert to Revoke 83,000+ SSL Certificates Due to Domain Validation Oversight

Jul 31, 2024 Web Security / Compliance
Certificate authority (CA) DigiCert has warned that it will be revoking a subset of SSL/TLS certificates within 24 hours due to an oversight with how it verified if a digital certificate is issued to the rightful owner of a domain. The company said it will be taking the step of revoking certificates that do not have proper Domain Control Validation ( DCV ). "Before issuing a certificate to a customer, DigiCert validates the customer's control or ownership over the domain name for which they are requesting a certificate using one of several methods approved by the CA/Browser Forum ( CABF )," it said . One of the ways this is done hinges on the customer setting up a DNS CNAME record containing a random value provided to them by DigiCert, which then performs a DNS lookup for the domain in question to make sure that the random values are the same. The random value, per DigiCert, is prefixed with an underscore character so as to prevent a possible collision with an actu...
New SnailLoad Attack Exploits Network Latency to Spy on Users' Web Activities

New SnailLoad Attack Exploits Network Latency to Spy on Users' Web Activities

Jun 28, 2024 Network Security / Data Protection
A group of security researchers from the Graz University of Technology have demonstrated a new side-channel attack known as SnailLoad that could be used to remotely infer a user's web activity. "SnailLoad exploits a bottleneck present on all Internet connections," the researchers said in a study released this week. "This bottleneck influences the latency of network packets, allowing an attacker to infer the current network activity on someone else's Internet connection. An attacker can use this information to infer websites a user visits or videos a user watches." A defining characteristic of the approach is that it obviates the need for carrying out an adversary-in-the-middle (AitM) attack or being in physical proximity to the Wi-Fi connection to sniff network traffic. Specifically, it entails tricking a target into loading a harmless asset (e.g., a file, an image, or an ad) from a threat actor-controlled server, which then exploits the victim's ...
