user-friendly social media platform by applying key object-oriented modeling
concepts. It entails the identification and definition of essential objects such as
"User," "Post," "Comment," and "Notification," each encapsulating specific
attributes and behaviors. Relationships between these objects, such as friendships,
content interactions, and notifications, are meticulously established.The project
emphasizes encapsulation to maintain data integrity, inheritance for shared behaviors
among objects, and polymorphism for flexible content handling. Use case diagrams
depict user interactions, while sequence diagrams showcase the flow of interactions
during critical scenarios. Class diagrams provide an overarching view of the system's
architecture, including classes, attributes, and methods .By undertaking this project,
we aim to create a modular, maintainable, and user-centric social media platform that
adheres to best practices in object-oriented modeling. Such a platform will offer users
a seamless and secure online social experience while facilitating future enhancements
and adaptability to changing user needs.

Conservation of Taksar through Economic RegenerationPriyankaKarn3
This was our 9th Sem Design Studio Project, introduced as Conservation of Taksar Bazar, Bhojpur, an ancient city famous for Taksar- Making Coins. Taksar Bazaar has a civilization of Newars shifted from Patan, with huge socio-economic and cultural significance having a settlement of about 300 years. But in the present scenario, Taksar Bazar has lost its charm and importance, due to various reasons like, migration, unemployment, shift of economic activities to Bhojpur and many more. The scenario was so pityful that when we went to make inventories, take survey and study the site, the people and the context, we barely found any youth of our age! Many houses were vacant, the earthquake devasted and ruined heritages.
Conservation of those heritages, ancient marvels,a nd history was in dire need, so we proposed the Conservation of Taksar through economic regeneration because the lack of economy was the main reason for the people to leave the settlement and the reason for the overall declination.

11. Wireless Standards - 802.11a, 802.11b/g/n, and 802.11ac
• 1997 IEEE ( Institute of Electrical and
Electronics Engineering ) created First WLAN
• Called as 802.11
• 802.11 only supports max network BW = 2
Mbps (to slow for most of application )
12. WLAN Operation
• Wireless LAN (WLAN) Can operate in 2
different frequency ranges
• 2.4GHz (802.11 b/g/n )
• 4.9 or 5GHz (802.11 a/h/j/n)
• Note : your wireless card can only be on one
channel ( it has single radio )
• Every country has allowed channel ,users and
maximum power levels
13. • Fair distribution of clients
across channels
• eg. Channel 1, 6, 11
• Fair distribution of clients
across bands
• eg. 2.4-GHz and 5-GHz
Channel 1
Channel 6
Channel 11
17. Wireless Encryption
• The main source of vulnerability associated
with wireless networks are the methods of
encryption. There are a few different type
of wireless encryption including:
• WEP
• WPA
• WPA2
18. WEP
• Stands for Wired Equivalent Privacy.
• WEP is recognizable by the key of 10 or
26 hexadecimal digits.
19. WPA or WPA2
• Stands for Wi-Fi Protected Access
• Created to provide stronger security
• Still able to be cracked if a short password is
used.
• If a long passphrase or password is used,
these protocol are virtually not crackable.
• WPA-PSK and TKIP or AES use a Pre-Shared
Key (PSK) that is more than 7 and less than 64
characters in length.
20. Why WPA ?
WEP (Wired Equivalent Privacy )broken
beyond repair
if you are using 64 bit or 128 bit key WEP will be broken
21. Weaknesses of WEP
1. Poor key management
• WEP uses same key for authentication/encryption
• Provides no mechanism for session key
refreshing
• Static Key encryption used
2. One-way authentication
22. WEP Replacement
WPA WPA2
Long Term Solution
Use CCMP ( Counter Mode Cipher
Block Chaining Message
Authentication Code Protocol )
Based on AES
Hardware Change Require
Intermediate solution by Wifi-
Alliance
Use TKIP (Temporal Key Integrity
Protocol )
Based on WEP
Hardware change not required
Firmware update
Personal Enterprise Personal Enterprise
PSK 802.1x + Radius PSK 802.1x + Radius

28. PBKDF2
• Password Based Key Derivation Function
• RFC 2898
• PBKDF2 (Passphrase, SSID,ssidLen,4096,256 )
• 4096 - Number of times the passphrase is
hashed
• 256 - Intended Key Length of PSK
29. How does the Client know ?
• Beacon Frames ?
• Probe Response Packets from the AP ?
• Can be used to create a WPA/WPA2 Honeypot
as well!
30. How WEP Works
1) We try to collect large number of data
packets
2) Bunch of large data packet contains weak IV
3) We Run it with the algorithm or aircrak-ng
and get the key
Then how to crack WPA-PSK ?

32. Pairwise Transient Key
• PTK = Function (PTK ,ANounce, SNounce,
Authenticator MAC ,Supplicant MAC )
PMK= Pre-Shared Key (Pairwise master Key)
ANounce = Random by AP
SNounce = Random by Client
Authentication MAC = AP MAC
Supplicant MAC = Client MAC

36. External Wireless Card
• Alfa Networks AWUS036H
USB based card
• Already integrated with
Backtrack and Kali
• Allows for packet sniffing
• Allows for packet injection
• We will use this in our
Demo session
37. Software Setup
• Run Kali Linux on VM machine
• Connecting Alfa Adapter
38. Understanding Wireless Sniffing
• Wireless : Monitor mode
• When you put card in monitor mode then it will
accept all the packet it is seeing in the current
channel
• Inbuilt tool in Kali which helps in quickly put card
into monitoring mode and sniff the packets
• Will use Tool name : airmon-ng to put card in to
monitor mode ( part of aircrack sweet of tools )
39. Some Basic Terms
• MAC address or physical address is a unique
identifier assigned to network interfaces for
communications
• Access point >> Wireless router
• SSID (service set identifier) >> Network Name
• BSSID (basic service set identification ) >> MAC
address of the access point
40. Using KaliLinux or BT
• Some Basic Backtrack Terms >>
• Wlan0 – wireless interface
• Mon0 – monitor mode
• Handshake :-refers to the negotiation process
between the computer and a WiFi server using WPA
encryption.
Needed to crack WPA/WPA2.
• Dictionary - consisting the list of common
passowords.
• .cap file – used to store packets.
41. Tools Used
• Airmon-ng >> Placing different cards in monitor
mode
Airodump-ng (Packet snniffer ) >> Tool used to listen
to wireless routers in the area.
Aireplay-ng ( Packet injector ) >> Aireplay-ng is used
to inject frames.
– The primary function is to generate traffic for the
later use in aircrack-ng for cracking the WEP and
WPA-PSK keys.
• Aircrack-ng >> Cracks WEP and WPA (Dictionary
attack) keys.
43. Lets Start
This will list all of the wireless
cards that support monitor (not
injection) mode.
The “(monitor mode enabled)”
message means that the card has
successfully been put into monitor
mode. Note the name of the new
monitor interface, mine is mon0.
44. • Airodump will now list
all of the wireless
networks in your area.
45. • airodump-ng –c [channel] –
bssid [bssid] –w
/root/Desktop/ [monitor
interface]
Replace [channel] with the
channel of your target
network. Paste the network
BSSID where [bssid] is, and
replace [monitor interface]
with the name of your
monitor-enabled interface,
(mon0).
46. • Airodump with now monitor
only the target network,
allowing us to capture more
specific information about it.
NOTE :
• What we’re really doing now is
waiting for a device to connect
or reconnect to the network,
forcing the router to send out
the four-way handshake that
we need to capture in order to
crack the password.
48. Upon hitting Enter, you’ll see aireplay-ng send the packets, and within
moments, you should see this message appear on the airodump-ng screen!
49. Final Step
• aircrack-ng -a2 -b [router bssid] -w [path to wordlist]
/root/Desktop/*.cap
• -a is the method aircrack will use to crack the
handshake, 2=WPA method.
-b stands for bssid, replace [router bssid] with the
BSSID of the target router, mine is 00:14:BF:E0:E8:D5.
-w stands for wordlist, replace [path to wordlist] with
the path to a wordlist that you have downloaded. I
have a wordlist called “wpa.txt” in the root folder.
/root/Desktop/*.cap is the path to the .cap file
containing the password
50. If the phrase is in the wordlist, then aircrack-ng will
show it too you like this
