Đặng Thanh Tùng (also known as “Tungtata”) is a founder of MiFirm / Phone Info Pro / SamFw / Trạmsạc.app. I am calling him a scammer because of his “SamFW Tool” package (v5.4) contains malicious code.
For years, my crypto wallet was untouched and the wallet remained safely on my computer. After I installed “SamFW Tool” (v5.4), my entire wallet balance was drained. In addition, my data appears to have been wiped: text files were shredded, and multiple files were irrecoverable.
This happened immediately after installing the tool. I believe the tool includes malware or code that injects and runs unwanted actions on the computer. I am currently alone trying to warn others not to install this tool.
I’m not making this up I am a victim and I lost a significant amount. When I tried to seek clarification, the scammer blocked me and told me to go to the police.
I’m asking for help: guidance on how to report this properly, preserve evidence, and protect others from falling victim.
