Gnsyihong Ransomware

Gnsyihong is a dangerous ransomware infection that encrypts files, appends a unique ID along with the .gnsyihong extension, and demands a ransom from victims for decryption. Discovered via VirusTotal sample analysis, this malware operates similarly to other notorious ransomware families such as MoneyIsTime, Hush, and Tianrui.

Once on a system, Gnsyihong renames files like 1.jpg to 1.jpg.{C13ECE96-7076-9D73-914B-5F2CBAAA094E}.gnsyihong, making them inaccessible. Alongside the encrypted files, it drops a ransom note in a file named README.TXT, threatening victims with data leaks and reputational damage if payment is not made promptly.
