Kurt’s key points
The convenience of free online tools often blinds us to the risks they take. Many users believe that if the website looks professional or ranks high on Google, it must be safe. Cybercriminals understand this mentality and make the most of it.
The real problem is not only the malware-connected converter, but also the habit of trading security without further consideration for convenience. The internet is full of free services provided at hidden costs of stolen data, financial fraud or device tradeoffs. Instead of trusting every tool that provides a simple solution, think critically when uploading a file or clicking the download button.
