Bounce URLs - Basic Protection against Malicious URLs

input:

[ IPv4 address | IPv6 address | URI | DNS name ]

output:

The Bouncer will lookup the DNS name or the IP address contained in the URI in a few major Black Lists. If the URI , IP address , or DNS name pass the test , the bouncer will redirect you there after a few seconds.

Any of the sites to which Bouncer redirects you may host offending content, malware, or phishing hooks.

Proceed at your own risk.


The Bouncer transforms plain DNS names , plain IPv4 addresses , and plain IPv6 addresses to HTTP URLs.

The Bouncer will bounce URIs using the protocols used often with web browsers: HTTP , HTTPS , and FTP.

The Bouncer runs a basic test against the host you are destined.
For a more thorough test consult dns/bl for domain names and ip/dnsbl for IPv4 address.

The Bouncer is ideal when you need to link to URIs beyond your control or to hide your referrer.

Examples of using url/bouncer.

The Bouncer waits for 4.5 sec before redirecting.
If you do not like the 4.5 sec wait time before the redirection you may use one of the following:
/url/bouncer/1
/url/bouncer/2
/url/bouncer/3
/url/bouncer/4


/url/bouncer/1 waits 0.5 sec before redirecting and it may be used in the same way.
eg:https://ipduh.com/url/bouncer/1/?http://alog.ipduh.com

/url/bouncer/2 waits 1.5 sec before redirecting and it may be used in the same way.
eg:https://ipduh.com/url/bouncer/2/?https://alog.ipduh.com

/url/bouncer/3 waits 2.5 sec before redirecting and it may be used in the same way.
eg:https://ipduh.com/url/bouncer/3/?https://alog.ipduh.com

IPduh.com/ip/srv bot

ip/srv bot is called the piece of software that does the scans or looks up the cashed scans. The scans are cashed for no fixed periods of time. The ip/srv bot always attempts to pass the asker's IP address to the web server listening on the scanned IP when it attempts a new (non-cached) scan. The ip/srv bot always acts at someone's request and never picks arbitrary hosts to lookup.

If you are a server administrator who does not want his server's IP to be scanned by ip/srv please tell IPduh so. If you are a server administrator that wants to know who requested an ip/srv scan, search your web server's logs for IPduhSrvBot.

The ip/srv agent signature on http daemons listening on port 80 or port 443 looks like:

"Mozilla/5.0 (compatible; IPduhSrvBot/VERSION; for/192.0.2.222; +http://ipduh.com/about/#ip-srv-bot)"

where: 192.0.2.222 is the IP address of the IPduh user who requested the first ip/srv scan, and VERSION is [0.0.1 - 0.9.9].

In an effort to not be a nuisance to the whois servers dns/whois caches whois queries for at least 15 days.

dns/bl    Tools Menu
Domain name URIBL and IP BLack List lookup

input:

a DNS domain name

output:

The URI Black Lists

  1. Google Safe Browsing - Google Safe Browsing FAQ

    This is a list of sites involved in phising or sites dedicated to the spread of malware.

  2. URIBL - uribl.com

    URIBL lists domain names found in URIs in the body of spam messages. These domain names may be used in one or more of the following categories of web sites: spamadvertized sites that are trying to sell something, phising sites, sites that host malware or used by malware, sites that infect visitors with malware.

The IP Black Lists

The IP Black Lists queried for every DNS related IP address are the same with the ones queried by ip/dnbl.

Examples of using dns-bl

For each of the DNS related IP addresses of the domain name dns/bl does not print IP Black Lists that answered "not listed".
You could use dns/bl/verbose if you want to see everything printed.

The domain names listed in the URI Black Lists are: dedicated to the propagation of malware, used for phising, used for spamming, or advertized though spamming.

IPduh suggests to not use your browser to visit any of the domain names listed on the URI Black Lists.

phishing site: Forgery or imitation of another website, designed to trick users into sharing personal or financial information. Entering any personal information on such site may result in identity theft or other abuse of the information entered.

malware site: A site that contains malicious software that could be downloaded to a user's computer without the user's content. A site used in controlling infected computers and coordinate malicious attacks or attempts to spread software viruses and other malicious software.

It is possible for the lists used by dns/bl to contain outdated or false information. It is possible that the lists compiled by IPduh to contain errors. The IPduh experience shows that the external lists chosen and the lists compiled by IPduh have a low false/positive ratio.

dns    Tools Menu

      TTL is an unsigned 32 bit integer that defines the number of seconds that a record may be cached.

Examples of using dns with GET requests


Note

For better results use the registered domain name example.com and do not use subdomains like www.example.com

There are cases that subdomain zones are delegated to name servers different than the domain authoritative name servers, and the subdomain has a different set of DNS records.


To see the root nameservers for a Top Level Domain use "TLD." and not just "TLD"


For International Domain Names, just use their UTF8 encoded form

ip/traceroute    Tools Menu
IP traceroute

Trace packets on their route from an Internet host in AS2490 along their route to another IPv4 Internet host.

input <

An Internet IPv4 address

output >

If the IP address entered is a routable Internet IP address, the intermediate routers along the IP path from IPduh to the IP address entered.

anonymity-check    Tools Menu

The anonymity-check shows what a web server can see or deduce about a web user. The web user information leaked to the WWW servers varies and depends on the web user's system, browser, settings, and local or proxy network. Even though the anonymity-check was intended to be used as a tool to demonstrate ways used by many sites to track web users, to check the anonymity of a connection through an HTTP proxy , check the integrity of an HTTP conversation, and test a Tor setup , it is more commonly used to find out the browser and network settings when troubleshooting. The anonymity checker is also a good way to find out if your privacy plugin conceals or ruins your Privacy.

Anonymity-check performs a plethora of tests and it is enhanced with new tests at a regular basis.
For the most part it reports only its finds.

Some of the Anonymity-check checks:
  1. Searching the HTTP headers for proxy traces.

    Some common HTTP headers used by web proxy servers are the following.

    1. HTTP_FORWARDED
    2. HTTP_X_FORWARDED_FOR
    3. HTTP_VIA
    4. HTTP_PROXY_CONNECTION
    5. HTTP_PROXY_ID
    6. HTTP_XROXY_CONNECTION
    7. HTTP_PROXY_CONNECTION
    8. HTTP_CLIENT_IP

  2. If cookies are accepted,anonymity-check processes the *leg cookies which hold information about the client's earlier visits and the previous IP address.

  3. The anonymity checker attempts to virtually ( it does not really store any of your inforamtion to the IPduh systems ) track you through an ETag.

  4. If Java is enabled, anonymity-check attempts to figure out your private IP address along with your computer's host name. None of this information is sent back to IPduh.

  5. Anonymity-check looks at the IP packets coming from your system or proxy system. This way it attempts to find out the MTU and advertised MSS along with information about your OS, your uptime, whether you are behind a NAT router or a firewall, your link type, and the number of the intermediate routers.

  6. Anonymity-check attempts to print the referral URI and the visiting system's host name as seen in the HTTP headers.

  7. Anonymity-check shows a report about your public IP addess. This report contains the same information with ip.

  8. Anonymity-check prints your user agent information as seen in the HTTP headers.

  9. Anonymity-check attemps to figure out the language(s) set to default on your web browser.

  10. If javascript is enabled on your browser, anonymity-check
    1. prints the cookies set by IPduh
    2. the visiting system's screen dimensions
    3. the character string identifying your WWW user agent.
    4. the plugins installed on the web browser, if any
    5. the operating system and the operating system vendor if available
    6. Attempts to store information about your visit on your system.
    7. If the Flash plugin is installed and enabled the anonymity checker attempts to store information about your visit on the Flash Local Share Object.
    8. Attempts to find previously stored information about your visits on your system.

  11. The Anonymity checker attempts to find the cashing name servers used by your system and print links to more information about them.

  12. The Anonymity checker attempts to detect anomalies such as missing or extra headers and HTML injections in the HTTP conversations between you system and IPduh.

Note

To see all the anonymity-check finds visit it two times in a browsing session, then do what you usually do when you want to clean up your browsing history and visit the Anonymity Checker again.

To encrypt your communication with the anonymity checker use https://ipduh.com/anonymity-check.

To use TLS - SSL encryption in between your browser and IPduh you may need to trust the IPduh Certificate Authortity - install the IPduh CA public certificate.

To automate your public IP address lookup you could use https://ipduh.com/my/ip.

Most privacy and anti-tracking Firefox plugins tested against the anonymity-check, so far ( 1330538493 ), failed to deliver what they promise. Actually, 90% of them are completely useless or do Privacy Concealing like it is 1996.
