Family Cyber Exploit

hay gays kembali lagi bersama gw Yukinoshita47 kali ini gw kembali menulis write up CTF wkwkwkwkwk gw emang hobi CTF sekarang daripada deface dan lain2

kali ini writeup tentang encryption sebenarnya. tapi

oke apa challenge nya kali ini ya challenge ada di gambar bawah ini

nah ini challenge ada angka aneh:v

000122 155 170 150 132 172 157 147 126 61 122 000111 145 61 144 150 143 61 71 117 115 110 122 000146 131 62 150 150 142 107 170 154 142 155 000144 160 142 155 144 146 115 62 64 167 144 000127 144 157 146 121 75 75


kunci nya liat digit angka nya maksimal nya berapa dalam challenge ini maksimal angka nya adalah 7 jadi kemungkinan besar adalah bilangan octal mungkin kalian yang belajar Teknik Elektronika Digital Pasti tau lah.

Berikut tabel Teknik Elektronika Digital Numbering Sistem nya biar tau kalian beda nya Binary, Octal, Decimal, dan Hexa Decimal itu apa :v


nah disini gw convert aja dari octal ke plain text kalo hasil nya seperti ini

RmxhZzogV1RIe1dhc19OMHRfY2hhbGxlbmdpbmdfM24wdWdofQ==

kemungkinan adalah base64





 biar pasti kita cek aja



 dan ternyata emang base64


 kita decode aja dan jadi nya adalah

RmxhZzogV1RIe1dhc19OMHRfY2hhbGxlbmdpbmdfM24wdWdofQ== adalah Flag: WTH{Was_N0t_challenging_3n0ugh}


 flag nya adalah WTH{Was_N0t_challenging_3n0ugh}


 done


oke cukup gampang kan kunci nya adalah pastikan lu rajin mikir kalo mau main CTF ini lumayan buat ngasah otak juga sekaligus lu tau sampai dimana kemampuan lu.

oke cukup sampai disini aja write up nya ingat write up adalah dokumentasi formalitas :v

sekian dan terimakasih

hay gays kali ini gw mau share write up lagi ne kali ini gw main di CTFLearn oke challenge kali ini Cryptography

berikut ini soal challenge nya

Kill the Killer
BY POPMAN

HELP! A MURDERER KILLED MY SON! I KNOW THE PERSON THAT KILLED YOUR SON HIS NAME WAS ._ _. _.. _.__ AND KILLED HIM.

dan challenge ini pada saat write up ini dibuat baru 24 solved nya ada apa dengan heker dunia ??


bagian ._ _. _.. _.__ adalah cryptography nya dan dari bentuk nya keliatan nya seperti kode morse mungkin yang rajin ikut Pramuka dan yang ikut Diksarmil pasti tau.

jadi cukup terjemah kan saja biar gak pusing pake translator aja

jadi ._ _. _.. _.__ = ANDY



 submit flag nya adalah ANDY

dan voila SOLVED


cukup mudah kan :v jika kalian masih juga bilang ini artikel gak perlu di post gw ingatin sekali lagi ya ini write up CTF cuma buat formalitas dokumentasi.

udah itu aja Sekian Dan Terimakasih.

 hai gays kembali lagi dengan gw Yukinoshita 47 hahaha kali ini gw share tutorial sederhana tp bermanfaat buat tukang bokep kayak lu lu semua wkwkwkwkwk

ok langsung aja ya




pertama masuk ke direktori webserver yang mau lu buat disini gw mau buat direktori webserver nya yaitu folder Videos

jd karena folder nya udah ada jd gw masuk aja dengan menggunakan perintah

cd Videos

kemudian tekan enter


untuk menjalankan webserver nya cukup gampang cukup masukkan perintah

python -m SimpleHTTPServer

kemudian tekan enter maka akan muncul ip 0.0.0.0 dan port 8000


cek webserver nya di browser http://0.0.0.0:8000 contoh jika berhasil webserver nya jalan maka akan muncul seperti gambar dibawah ini.



disini ip gw 192.168.100.13 karena port nya 8000

jadi teman 1 jaringan mengakses nya di browser mereka adalah http://192.168.100.13

contoh gambar dibawah ini

 karena disini kami berbagi bokep ya biase dibuka dan didownload


yeeahhh download bokep sedang berlangsung

 trus bagaimana cara mematikan webserver nya ?

gampang tekan aja CTRL C



cukup mudah kan wkwkwkwkwkwkwkwk oke sampai disini saja tutorial sederhana nya sampai jumpa di tutorial berikut nya ya gays

sekian dan Terimakasih

hai gays kembali lagi di tutorial kali linux gw Yukinoshita 47 mau share troubleshooting metasploit yang umum terjadi di kali linux yaitu pas mau load module atau plugin muncul error database not connected.


bagaimana solusi nya ? ok let's roll nigga pertama jalankan service postgresql nya dengan menggunakan perintah

service postgresql start

kemudian tekan enter


kemudian jalankan perintah

msfdb init

kemudian tekan enter


jalankan metasploit dengan menggunakan perintah msfconsole lalu tekan enter kemudian masukkan db_status kemudian tekan enter jika muncul tulisan postgresql connected to msf berarti metasploit sudah bisa digunakan.



oke cukup mudah kan dan sampai jumpa di artikel-artikel berikut nya.

sekian dan terimakasih..

challenge kali ini adalah Eye of Sauron kategori nya Malware Reverse Engineering

inilah penampakan eye of sauron




Q : WOI BNGST KNTL MMQ JMBT MATA DAJJAL ITU MAH
A : Lu tau tuh Mata Dajjal tp nape lu males ibadah ?

udah udah cukup intermezzo nya mari kita ke TKP

oke berikut ini challenge nya

Can you find the key to pass? Link:https://s3-eu-west-1.amazonaws.com/talentchallenges/Reverse/Inkie.zip

 

gw download dulu file nya dan gw copy file Inkie.exe nya karena yg 1 buat di reverse atau dibongkar yg 1 lagi buat dijalanin.



challenge nya seperti ini disuruh nyari key nya




disini gw nemuin kode hash pada bagian InitializeComponent() : Void di FormLabel2, FormLabel3, FormLabel4, dan FormLabel5 lebih detail cek di gambar



ini Source Code bagian InitializeComponent() : Void

jadi hash nya

label2 = d0248b4e
label3 = 47886655
label4 = 83f05688
label5 = c154b6ea

kita coba buat key nya dari label2, label3, label4, dan label5 jadi key nya = d0248b4e4788665583f05688c154b6ea


kita test dan ternyata fail


kita coba cara ke dua yaitu urutan nya  label5, label4, label3, dan label2 jadi key nya = c154b6ea83f0568847886655d0248b4e

dan hasil nya fail juga


kebetulan gw baru dapat ide  gw gunakan pola kita  key nya dari label2, label3, label4, dan label5 jadi key nya = d0248b4e4788665583f05688c154b6ea ya kan tp kali ini gw balik seperti efek cermin jadi kurang lebih.

semula key nya = d0248b4e4788665583f05688c154b6ea

gw tandai merah ternyata ada sedikit jebakan gw cek di bagian btnCheck_Click(Object,EventArgs) : Void


script nya di bagian btnCheck_Click(Object,EventArgs) : Void

.method private hidebysig instance void btnCheck_Click(object sender, class [mscorlib]System.EventArgs e) cil managed
{
    // Method Start RVA 0x2124
    // Code Size 43 (0x2b)
    .maxstack 8

    L_0029: pop
    L_002a: ret
}

semula key nya = d0248b4e4788665583f05688c154b6ea
dibalik pake efek cermin istilah nya diubah menjadi key nya ae6b451c98650f3855668874e4b8420d

karena gw liat ada bagian angka yang mirip tapi beda 2 digit di btnCheck_Click(Object,EventArgs) : Void jadi key nya gw ubah menjadi dari 47886655 menjadi 47889955 jika dibalik pake efek cermin menjadi 55669974 dan jadi key nya = ae6b451c98650f3855669974e4b8420d

dan kita coba ternyata berhasil


 flag nya adalah ae6b451c98650f3855669974e4b8420d


dan berhasil


oke cukup sampai disini write up kali ini gw akan bikin write up CTF yang lainnya karena gw beberapa event CTF juga gw ikutin kalo ada challenge nya yang berhasil gw selesaikan pasti gw bikin write up nya buat dokumentasi dan bukti nya.

TOLONG JANGAN BULLY KAMI TERUS KAMI BUKAN SIAPA-SIAPA WKWKWKWKWKWKWK

sekian dan terimakasih
