"REFUND STUFF.zip" is a dangerous, frequently encountered file name used in social engineering scams to deliver malware, including infostealers, Remote Access Trojans (RATs), and ransomware. These archives often promise illegal refund methods but instead target users with data theft, making it critical to avoid downloading them from untrusted sources. If exposed, disconnect from the internet, run a deep anti-malware scan, and change all sensitive passwords immediately.
