🤖Mastering SSRF Exploits: Unraveling Gopher's Web of Intrigue

As we delve deeper into the intricate world of Server-Side Request Forgery (SSRF) attacks, our journey takes an intriguing turn as we encounter the enigmatic Gopher protocol. Much like a cryptic cipher, Gopher opens doors to a realm of digital manipulation, allowing attackers to orchestrate their clandestine operations.

The Gopher Protocol: A Digital Enigma

Among the various SSRF techniques, the manipulation of the Gopher protocol stands out as an art form in itself. This protocol, originally designed for document retrieval, becomes a canvas for attackers to craft their exploits. Let's dissect a fascinating example to unveil the inner workings of Gopher:

• The Gopher Artistry: The attacker's canvas is a URL that reads like a coded message:

https://target.com/page?url=gopher://127.0.0.1:25/[e-mail][e-mail]%[e-mail]%3E%250d%250aTo: <[e-mail]> %0d%250aDate: Fri, 13 Mar 2020 03:33:00 -0600%250d%250aSubject: Hacked%250d%250a%250d%250aYou've been exploited :(%20%21%250d%250a%250d%250a%250d%250a.%250d%250aQUIT%250d%250a

At first glance, it appears as a sequence of cryptic characters. However, this is a carefully constructed Gopher request that executes a series of commands:

• HELO localhost: Like an introduction, this command initiates communication, saying "hello" to the local server.

• MAIL FROM:[e-mail] and RCPT TO:[e-mail]: These commands mimic email correspondence, establishing the sender and recipient of a message.

• DATA: The stage is set for data transmission.

• From: [Attacker] [e-mail] to [e-mail]: The attacker crafts a message, assuming the identity of the sender.

• Date: Fri, 13 Mar 2020 03:33:00 -0600: The message bears a timestamp, adding a layer of authenticity.

• Subject: Hacked: The message's subject line sends a chilling message.

• You've been exploited :( !: The body of the message holds the ominous truth.

• .: A period signifies the end of the message.

• QUIT: Finally, the command signals the termination of communication.

Conclusion: The Artistry of Gopher Exploits

As we conclude our journey into the world of SSRF exploits and the enigma of Gopher, we must remember that these techniques, while fascinating, have profound security implications. Gopher, in the hands of an attacker, becomes a tool for deception and manipulation.
