Staying Anonymous

there are 4 methods:

  • Onion network
  • Proxy servers
  • VPN
  • Private encrypted email

Every request sent across internet includes the source IP. The request hops between different routers before reaching the destination. To see all hops, we can use traceroute.

Tor​

uses the Onion Router System, a network of 7k routers that encrypt the data, destination and source address of each packet. Each hop is a cycle of encryption/decryption. So if someone intercepts one of the messages at one of the hops, they can only see the previous hop information rather than the original source address.

Proxy servers​

Traffic will look like it came from the source address but will in fact look like a different address.

proxychains is a tool that can be used to run a command through a chain of proxies:

proxychains nmap -T4 -A 10.10.10.1

example proxychains configuration (/etc/proxychains.conf) has 3 proxies set up:

# ProxyList section, defaults to tor
[ProxyList] 
# add proxy here... 
socks4 114.134.186.12 22020 
socks4 188.187.190.59 8888 
socks4 181.113.121.158 335551

uncomment dynamic_chain and strict_chain to have proxychains proxy requests through each proxy and skip if one fails.

uncomment random_chain (and comment strict_chain) so each time we use proxychains , the proxy will look different to the target, making it harder to track our traffic from its source. We can also set the number of proxies by changing the value next to chain_len
