This host belongs to an independent security researcher and is used as an out-of-band interaction endpoint while testing applications under authorized bug bounty and vulnerability disclosure programs.
If you are investigating a DNS lookup or HTTP request to
*.oob.svg.bd originating from your infrastructure, it is almost certainly the
result of a payload submitted to one of your own applications during authorized
testing. No exploitation beyond proving the interaction is performed.
