FILE FOLDER DALAM PENDRIVE JADI SHORTCUT..?

Folder-folder yang jadi shortcut

Langkah-langkahnya :

• Go to ‘Start’ -->’Run’ --> type ‘cmd’ and click OK untuk ke Command Prompt. (If running Windows Vista/7, klik “Home + R” , then taip ‘cmd’. Note: butang ‘Home’ selalunya sebelah ‘alt’).

• Masukkan command attrib -h -r -s /s /d h:\*.* (assume yang drive letter adalah H: dalam ‘My Computer’, jangan lupa replace kalau drive letter adalah berbeza).

• Tekan ‘Enter’, then check file/folder dalam removable disk sama ada visible atau tak? If YES, tahniah!!.. Anda berjaya...

AMALI : PHISHING

(dibuat hanya dalam server 10.1.0.13)

Keperluan :

• Website yang hendak dibuat phishing(cth : website UNIMAP).
• Software  Putty.

1.Go to website UNIMAP, then save Save Page As html.

Website UNIMAP(asli)

Folder yang save page website UNIMAP

2.Copy “data” dan “write”. Then paste ke dalam folder unimap.

“data” dan “write” disimpan dalam folder unimap

 

3.Buka page UNIMAP menggunakan wordPad. Find ‘username’, ‘password’ dan ‘action’.

 name=“ssousername”

name=“p_request”

Tukar bahagian action kepada [action=“write.php”] seperti gambar di bawah.

action=“write.php”

4.Buka write(dalam folder UNIMAP). Pastikan bahagian ‘username’ dan ‘password’ adalah sama dengan ‘username’ dan ‘password’ dalam page UNIMAP. (selepas password, masukkan url website UNIMAP yang asli seperti dalam gambar di bawah) - FUNGSI : supaya user akan redirect ke website asli setelah login di phishing website.

 

5.Allocate folder UNIMAP tadi dalam server 10.1.0.13.

Folder UNIMAP yang telah disimpan dalam server 10.1.0.13

6.Running software Putty. Masukkan IP address server, then klik SSH.

7.Login as root. Masukkan password linux123. Then, masuk ke folder yang simpan folder UNIMAP.

Folder UNIMAP yang ada dalam folder netsec_wifi

8.Masukkan command “chmod<>-R<>777<>nama folder” seperti di bawah.

 

9.Check sama ada proses phishing berjaya atau tidak. Masuk semula ke website UNIMAP(melalui web browser server). Login seperti biasa. If selepas klik butang login, website UNIMAP(asli) akan terpapar.

Login pada  website palsu

Website UNIMAP yang asli

 

10. Untuk lihat semula username dan password yang berjaya kita capture. Go to folder UNIMAP > data.

SHARING BROADBAND(CELCOM)

If nak setup sharing untuk Celcom broadband
Untuk Komputer A :
1. Go to Control Panel > Network Connection > Vodafone Mobile Connect(Celcom broadband).

 
2. Right click pada Vodafone Mobile Connect > Properties > Advanced. Then klik pada yang berkenaan.

3. Kemudian masuk semula ke Network Connection. Simbol tangan akan tertera menandakan broadband dah boleh share.

4. Set IP address pada Local Area Network(LAN) Komputer A.(supaya Komputer B dapat connect ke Komputer B melalui LAN).

Untuk Komputer B :
1. Disable connection pada LAN, then enable semula.(supaya Komputer B dapat terima IP address baru).
