What do I do if my WinZip trial has expired? 1. Since WinZip is so widely used around the world and pretty much everyone started off with the trial first, we decided to create this step-by-step guide to show you what you can do after WinZip’s trial expires. However, that begs the question: What should you do after the WinZip trial ends? WinZip also falls under the category of high-quality software, and one testament to that is that you do indeed have to pay for it.įortunately enough, the software can be used over a period of 30 days for free, during which you have plenty of time to test out its functionality. The problem with most good high-quality software is that you rarely ever find it for free, and even if you do, it’s probably open-source and very unstable because of the wide variety of contributors. However, if one wants to continue using the trial version, they should change WinZip’s settings so that the program does not automatically ask them for updates, rather they have to manually do them.Home › Fix › PC Software › WinZip trial expired To conclude, if one updates to WinZip 25, this issue is automatically solved as the newer version uses HTTPs. On the other hand, the trial period popup could also be exploited in a similar fashion with an example of one such notice shown below: As a result, unsuspecting user can launch arbitrary code as if it is a valid update. This means anyone on the same network as user running a vulnerable version of WinZip can use techniques like DNS poisoning to trick the application to fetch “update” files from malicious web server instead of legitimate WinZip update host. Other relevant info required to process the requestĮxplaining, Martin states in a blog post that,.What makes it even more dangerous is that the update request contains sensitive information that could be viewed by the attacker including the following:
Someone else who has the capabilities to see the program’s traffic this way can alter and steal the communicated text which would spell disaster for the victim. This communication is done in plaintext over HTTP rather than HTTPS which could be exploited by attackers to deliver malware.
Nonetheless, in the latest, it is in the news with a vulnerability found in WinZip 24.Īs identified by researchers from SpiderLabs at Trustwave Security, WinZip 24 was found using Wireshark that when the program sends requests to check for updates and display prompts of the free trial being over. Most of us are pretty well acquainted with WinZip, especially when on the receiving end of its prompts to obtain a license for further use. Other than malware delivery WinZip vulnerability also lets hackers carry out DNS poisoning and arbitrary code execution.
