 Wifi Passwords
 Mobile Login Cracking

11. MAFIABOY:

12. DOS ATTACK:
 To bring down an entire network
 -Each system connected to internet has
limited bandwidth available.
 [If our computer has bandwidth of 2mbps &
the criminal sends 100mbps of data then our
computer will crack]

13. TYPES OF DOS ATTACK:
1.Ping Of Death:
2.TearDrop:
1]Ping Of Death:
65,536 bytes is the size of data packet.
(Not Larger Attack)

14. .
2 TearDrop:
Data is broken down into smaller
chunks of data
e.g. 4000 Bytes
Chunk A 1-1500 bytes
Chunk B 1500-3000 bytes
Chunk C 3000-4000 bytes
DOS attack is extremely dangerous

15. STEGNOGRAPHY:
Hiding of any file or data into the other file
TYPES OF STEGNOGRAPHY:
1. Image STEGNOGRAPHY
2. Text STEGNOGRAPHY
3. Spam(Mimic) STEGNOGRAPHY

16. ROAD SIGN HACKING:

17. ATM MACHINE HACKING:

18. BEST SECURITY PRACTICES:
1. Install a FIREWALL: Zone Alarm (Free
Download)
2. Use an Antivirus: Update it Weakly
3. Use an ANTISPYWARE: PrevX, SpySweeper
