In case it was not possible to get an interview. Let's say a company doesn't need technical specialists. An attacker can use a phone or messenger. For example, you can call the company and ask them to connect with the system administrator. If the secretary pulled together and connected, then under the guise of an offer to sell consumables and office equipment, try to find out the equipment and software used on the network. It's not the most effective way, of course, but it's better than nothing.
Next, we recall the messengers. Through Skype, an attacker can try to find out the IP address of the corporate gateway. To do this, a hacker can try to send a file via Skype or Telegram. Next, using a packet analyzer, you can track which IP address the packets are going to. However, this method does not always work, sometimes there is another Skype server in the recipient's address.
