Ma kēia ʻatikala e hoʻopau mākou i ka hana 25th mai ka pūnaewele .
ʻIke hoʻonohonohoʻOi loa no ka poʻe makemake e aʻo i kahi mea hou a hoʻomohala i kēlā me kēia wahi o ka ʻike a me ka palekana kamepiula, e kākau wau a kamaʻilio e pili ana i kēia mau ʻāpana:
- PWN;
- cryptography (Crypto);
- ʻenehana pūnaewele (Network);
- hoʻohuli (Reverse Engineering);
- hōʻike kiʻi kiʻi (Stegano);
- ʻimi a hoʻohana i nā nāwaliwali o WEB.
Ma waho aʻe o kēia, e kaʻana aku au i koʻu ʻike ma nā forensics kamepiula, malware a me ka loiloi firmware, hoʻouka ʻana i nā pūnaewele uʻi a me nā pūnaewele wahi kūloko, ke alakaʻi ʻana i nā pentests a me nā hana kākau.
No ke kōkua ʻana iā ʻoe e hoʻomau i nā ʻatikala hou, lako polokalamu, a me nā ʻike ʻē aʻe, ua hana wau и ma ke kahua o I&KB. A me kāu mau noi pilikino, nā nīnau, nā manaʻo a me nā manaʻo .
Hōʻike ʻia nā ʻike āpau no nā kumu hoʻonaʻauao wale nō. ʻAʻole ʻae ka mea kākau o kēia palapala i kekahi kuleana no nā pōʻino i hana ʻia i kekahi ma muli o ka hoʻohana ʻana i ka ʻike a me nā ʻenehana i loaʻa mai ke aʻo ʻana i kēia palapala.
Hoʻoholo i ka hana otp
E hoomau kakou i ka pauku elua. E'ōlelo koke wau heʻoi aku ka paʻakikī ma mua o ka mea mua, akā i kēia manawaʻaʻole lākou e hāʻawi i ke kumu kumu o ka papahana. Mai poina e pili ana i ke kūkākūkā ma aneʻi (https://t.me/RalfHackerPublicChat) a ma aneʻi (https://t.me/RalfHackerChannel). E hoʻomaka kākou.
Kaomi ma ka ikona me ka pūlima otp. Hāʻawi ʻia mākou i kahi helu a me kahi awa e hoʻopili ai.
Hoʻohui mākou a nānā a puni ke kikowaena.
He hae ʻaʻole hiki iā mākou ke heluhelu, he polokalamu a me kāna code kumu. E nānā kākou i ke kumu.
E hoʻoponopono kāua. Lawe ka polokalamu i ka ʻōlelo huna ma ke ʻano he hoʻopaʻapaʻa.
A laila, mālama ʻia nā bytes 16 maʻamau i ka otp variable.
Hoʻokumu ʻia kahi faila me ka inoa maʻamau i loko o ka waihona tmp (ʻo ka 8 bytes mua he otp) a ua kākau ʻia he 8 bytes maʻamau iā ia (ʻo ka lua 8 bytes he otp).
No kekahi kumu, heluhelu ʻia ka waiwai o ka faila i hana ʻia a hoʻohālikelike ʻia me ka ʻōlelo huna i hoʻokomo ʻia.
ʻO kēia kahi e komo ai ka nāwaliwali. Aia ia me ka mālama ʻana i ka helu i hana ʻia i kahi faila. Hiki iā mākou ke kaupalena i ka nui o ka faila, no ka laʻana, i ka 0, a laila i ka kākau ʻana a me ka heluhelu ʻana, e hoʻohālikelike ʻia ka 0 me ka ʻōlelo huna. Hiki ke hana ʻia e like me kēia.
# ulimit -f 0
I kēia manawa, e holo kāua i ka papahana.
Loaʻa iā mākou kahi hewa. ʻAʻole ia he mea nui, hiki ke hana ʻia me ka hoʻohana ʻana i ka python like.
python -c "import os, signal; signal.signal(signal.SIGXFSZ, signal.SIG_IGN); os.system('./otp 0')"
Loaʻa iā mākou ka hae a me kā mākou maʻalahi 100 helu. A hoʻomau mākou: ma ka ʻatikala aʻe e hoʻopā mākou i ka Pūnaewele. Hiki iā ʻoe ke hui pū me mākou ma .
