In the 90s and early 2000s, before broadband took over, ISPs offered dial-up access through thousands of local phone numbers. Hackers and phreakers quickly realized these numbers could be exploited. By war-dialing exchanges and identifying modem handshakes, they could find valid ISP numbers, brute-force login credentials, and gain free internet access. Some would spoof caller ID or trick authentication systems into thinking they were paying customers. Entire lists of “free ISP dialups” circulated underground forums and BBSes, allowing global access through someone else’s phone bill or corporate lines.

This method was eventually curbed as ISPs upgraded authentication, moved to centralized radius servers, and broadband made dial-in obsolete. But for a brief time, exploiting dial-in access was a gateway to the early internet.

In the late 1980s and early 90s, a mysterious hacker known only as Kando made waves across private BBS systems and underground phreaking circles. Not much is known about their identity, but Kando was credited with releasing a series of clever, minimalist terminal hacks—scripts that could hijack modem handshakes or manipulate ANSI escape sequences to gain access or crash rival systems. Their work never made it to mainstream hacker zines, but among old-school sysops, the name still rings a bell. Some say Kando walked away before the internet boom, while others believe their fingerprints are still hidden in obscure .asc files floating around forgotten FTP mirrors.

Netcat was, and still is, the networking Swiss army knife.
Before modern pentesting suites and flashy UIs, netcat quietly did it all. Reverse shells, raw TCP file transfers, port scanning, even makeshift chat servers. All from a single terminal. Lightweight and deadly in skilled hands, it is just as useful today as it was decades ago.

Back in the early days of hacking and phreaking, there was no formal ranking system, just skill, reputation, and who you knew. But as the culture evolved, loose categories emerged.

Script Kiddie – Runs pre-made exploits without understanding them. Annoying but not a real threat.
Lamer – Worse than a script kiddie. Talks big but has no real skill.
Elite – The real deal. Masters of custom exploits, reverse engineering, and deep system knowledge.
Guru – Even beyond elite. Think of the cryptographers, OS developers, and hardware hackers shaping the future.

In the underground, respect is not about labels. You either have skills or you do not.
