WTHack : The Secret Message [Write Up]

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

Kali Linux : Membuat Webserver Sederhana Dengan SimpleHTTPServer

 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.

bagaimana cara nya agar webserver kita bisa diliat teman kita yang 1 jaringan

pertama kita liat ip LAN kita dengan perintah

ifconfig

kemudian tekan enter

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

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_0000: ldarg.0
    L_0001: ldfld [Inkie]Inkie.Form1::label3
    L_0006: ldstr "47996655"
    L_000b: callvirt instance void [System.Windows.Forms]System.Windows.Forms.Control::set_Text(string)
    L_0010: ldarg.0
    L_0011: call instance bool [Inkie]Inkie.Form1::ShallHePass()
    L_0016: brtrue.s L_001f
    L_0018: ldstr "you shall not pass"
    L_001d: br.s L_0024
    L_001f: ldstr "you shall pass"
    L_0024: call valuetype [System.Windows.Forms]System.Windows.Forms.DialogResult [System.Windows.Forms]System.Windows.Forms.MessageBox::Show(string)
    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
