Hacking Facebook By Using PHP Script | Social Engineering Attack | LAN And WAN (Same Or Different Networks)

This Video is absolutely for Educational Purposes only, please don't do any illegal activity. If you do then I'm not responsible for your illegal activity. The purpose of this video is to show you How hackers can hack your social media by using their own local servers.

Basically these type of attacks known as Social Engineering attacks or Phishing. Attacker just send the duplicate vulnerable HTML page to the victim, when victim enters any type of information to that vulnerable page it'll automatically received by the attacker.

Phishing is a form of fraud in which an attacker masquerades as a reputable entity or person in email or other communication channels. The attacker uses phishing emails to distribute malicious links or attachments that can perform a variety of functions, including the extraction of login credentials or account information from victims.

How phishing works

Phishing attacks typically rely on social networking techniques applied to email or other electronic communication methods, including direct messages sent over social networks, SMS text messages and other instant messaging modes.

Phishers may use social engineering and other public sources of information, including social networks like LinkedIn, Facebook and Twitter, to gather background information about the victim's personal and work history, his interests, and his activities.

Hacking by PHP

As PHP is server side scripting language so first of all you have need to install a local server (WAMP, XAMPP or LAMPP) over your system. Because if there is no any server running on your system then you can't even run your PHP script. So if you wanna do a programming with PHP this is the first step to download and install a server from the Internet. You can easily download and install servers by watching my videos. Just visit my YouTube channel and watch there.

Emulating Shellcodes - Chapter 1

There are many basic shellcodes that can be emulated from the beginning from the end providing IOC like where is connecting and so on. But what can we do when the emulation get stuck at some point?

The console has many tools to interact with the emulator like it was a debugger but the shellcode really is not being executed so is safer than a debugger.

target/release/scemu -f ~/Downloads/shellcodes_matched/drv_shellcode.bin -vv

In some shellcodes the emulator emulates millions of instructions without problem, but in this case at instruction number 176 there is a crash, the [esp + 30h] contain an unexpected 0xffffffff.

There are two ways to trace the memory, tracing all memory operations with -m or inspecting specific place with -i which allow to use registers to express the memory location:

target/release/scemu -f ~/Downloads/shellcodes_matched/drv_shellcode.bin -i 'dword ptr [esp + 0x30]'

Now we know that in position 174 the value 0xffffffff is set.

But we have more control if we set the console at first instruction with -c 1 and set a memory breakpoint on write.

This "dec" instruction changes the zero for the 0xffffffff, and the instruction 90 is what actually is changing the stack value.

Lets trace the eax register to see if its a kind of counter or what is doing.

target/release/scemu -f ~/Downloads/shellcodes_matched/drv_shellcode.bin --reg eax

Eax is not a counter, is getting hardcoded values which is probably an API name:

In this case this shellcode depend on previous states and crash also in the debugger because of register values. this is just an example of how to operate in cases where is not fully emulated.

In next chapter will see how to unpack and dump to disk using the emulator.
