Furthermore, companies and developers should ensure that their tools, scripts, and applications do not rely on filename extensions, but instead should check the file type based on the file headers - otherwise a URL could trigger unwanted or risky behavior from these tools and scripts. Hovering the mouse cursor over links can provide a preview of their actual intended URLs. Organizations and individual users can protect themselves from attacks that exploit TLDs by staying vigilant and exercising caution when receiving URLs with unfamiliar top-level domains (TLDs) and avoiding clicking on them unless certain that they are legitimate. However, we will continue to monitor any related URLs we come across and block them as needed in preparation for potential phishing campaigns. In extreme cases, organizations might resort to blocking all URLs using potentially exploitable TLDs since there is a high chance that they will be used for malicious purposes.Īs of today, Trend Micro has not yet received URLs related to these new TLDs from internal and customer cases. zip TLD with the delimiter, these websites could have been even more convincing as legitimate Zoom download URLs to potential victims.Īside from malware delivery, these TLDs could be used in other ways, for example as a command-and-control (C&C) server. In other words, the ” is just a delimiter. This just means that the URL before is, in practice, ignored and just act as a mask, whereas the one after the symbol is the actual target URL. In an example provided by Medium’s Bobby Rauch, accessing the URL shown in Figure 1 will direct a user to instead of. zip TLDs, one of the things that make it a potential security concern is the use of the operator on a website URL. These websites are often used as referrer URLs that redirect to the malicious URLs. The use of legitimate websites for masking malicious URLs to avoid detection and minimize suspicion is a technique that cybercriminals have used for a long time. Primary security concerns Hiding malicious URLs behind legitimate websites In this blog entry, we will examine these security risks while also providing best practices and recommendations on how both individual users and organizations can protect themselves from these hazards. Although seemingly harmless at first glance, it sparked discussion and debate across the internet since these domains can pose security risks due to cybercriminals exploiting them for malicious purposes. $.In May 2023, Google launched eight new top-level domains (TLDs) that included. set a handler to upload the files when the submit button is clicked you should possibly put code in here to clean up afterwards runs after all files have been uploaded or otherwise dealt with this pushes the done() callback into the global mentioned earlier it also fills in the filename so that it's obvious which meta boxes this is just to clone meta boxes for the user to fill in for each file this is the important custom function you need to supply other important parameters related to upload, read the documentation for details Url: 'upload.php', // upload handler, handles each file separately, can also be a function taking the file and returning a url If you want meta boxes to appear for each file, then you need to append the appropriate html on a per file basis to allow the user to fill them in.Ī summary of the code I would suggest is below: var uploads_to_call = // the global to store all the file upload callbacksįallback_id: 'upload_button', // an identifier of a standard file input element, becomes the target of "click" events on the dropzone You also need to store references to the done() functions that are provided to your custom function for each file, so that you can call them later, causing the files to be uploaded. To use the jquery extension you've chosen, you need to take advantage of the beforeSend option, and supply your own function. You should also download and use a later version of jquery than the one bundled with that sample code. You need to download and use the latest version from its project home for this to work. The sample code you have linked to appears to be using, which is written by Weixi Yen.
