So I set to work learning about modem hacking, telephony, and a lot about Asterisk. This was a challenge because not only did I not know anything about modem hacking, but I didn’t know anything about the wide world of telephony.įortunately, I had about two weeks to figure it out before the job started. My Introduction to AsteriskĮarly in my penetration testing career, I was tasked with performing a wardialing modem hacking gig-the client wanted to test their telephone network for modem-related weaknesses. In this post, we'll explain how security professionals can build a caller ID spoofer for purposes of simulating attacks and building internal awareness. Spoofing telephone numbers is a real-world tactic used by malicious actors as part of phishing campaigns, so it's a helpful capability for internal security teams to have in their arsenals as they defend their organizations against this common threat.

These tests should strive to be as real-world as possible in order to accurately simulate a malicious actor and learn from employees’ reactions and ascertain the level of risk they pose to the organization. These may include hiring third-party consulting companies as well as performing internal tests. Organizations with mature security programs often test their own internal awareness programs by performing social engineering campaigns (e.g., telephone pretexting) on their personnel.
