Introduction to Footprinting and Reconnaissance in Ethical Hacking

Footprinting is one of the most convenient ways for hackers to collect information about targets such as computer systems, devices, and networks. Using this method, hackers can unravel information on open ports of the target system, services running, and remote access probabilities.Since it is the initial phase of hacking it is really important to develop an accurate understanding of the entire process. The systematic footprinting of a target enables the attacker to get a blueprint of the target's security posture.In this article, we will get to know how malicious hackers perform footprinting on the organization or target's system, what all they can do, and how it will be harmful to businesses and individuals. On the other hand, white hat hackers who are well versed in footprinting will be able to improve the security of the organizations they work for. With systematic methodology, businesses can identify their vulnerabilities so they can patch and make changes in policy accordingly.Types of footprinting:Who is footprintingNetwork footprintingDNS footprintingCompetitive intelligenceEmail footprintingWebsite footprintingSocial EngineeringGoogle HackingHow to perform footprinting?Footprinting is the first step, during which the hacker gathers as much information as possible to find ways to enter a target system. For successful footprinting, the attacker needs to first check the visibility of the target and see how to gather related information on the internet through open sources. Through careful analysis, the attacker can determine the scope of potential entry points. The following information can be collected:Company namesDomain namesBusiness subsidiaries  IP AddressesBusiness emails  Network phone numbers  Key employeesand so on.In hacking terms, we can call it the "Front Door" of the castle on target.  The first step of footprinting is to determine what to attack to obtain the "footprint" of the target network which includes, but is not limited to the following:HostnamesNetwork address rangesExposed hosts  Exposed applications  OS and its versionsApplication and its versionsand many more.Apart from this, the attackers have to decide the scope of the target with regards to the entire organization or certain subsidiaries or locations. Based on the scope, they start to dig deep into the information like company web-pages, related organizations, employee details, contacts, e-mail addresses, currents events, locations, news, policies, disgruntled employees, mergers, acquisitions, or events to garner some clues, opportunities, and contacts for attackers.Methods of footprinting1. Port ScanningPort scanners are used to determine live hosts on the internet and find out which Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) ports are listening on each system, as well as which operating system is installed on the host. To identify the relationship of each host and potential security mechanisms between the attacker and targets, they use traceroutes.Tools:NSLookup - to perform DNS queries and zone transfersTracert - to create network maps of the target.Once port scanning and trace routing are done, attackers will create a network map that represents the target's internet footprinting.2. Google HackingDespite what you may infer from the name, this method does not involve hacking Google! This is a means by which you can collect information from the Google search engine in a smart way.Search engines have many features using which you can get uncommon, but very specific search results from the internet. Using these techniques, hackers and attackers perform a search using advanced operators, examples of which are given below.These types of operators can uncover much sensitive information that can potentially harm the target and should therefore not be revealed.Let's take an example. Go to google.com and paste this- allinurl:tsweb/default.htmYou will get more than 200 websites that have tsweb/default folder. Using this, the hacker gets a chance to get into the organization's servers. This is just one example. There is plenty of such information about targets available online, which hackers can take advantage of.3. Ping SweepIf the attacker wants to know which are the machines on your network that are currently live, they can perform a ping sweep. Ping uses ICMP packets to send echo requests to the target system,  and waits for an echo reply. If the device is not reachable, it will show a "request time out"; but if the device is online and not restricted from responding, it will send an echo reply back. Here are some tools used to perform ping sweeps through a range of devices that determine the active devices on the target network.NmapAngry IP scannerSuper Scan  Pinger etc.4.  Who is lookupThis method can be used to collect basic database queries like domain name, IP Address block, location, and much more information about the organization.Example of FootprintingLet's see an example of footprinting using the Linux tool p0f.p0f is a passive TCP/IP stack fingerprinting tool to identify the system running on machines that send network traffic to the box it is running on, or to a machine that shares a medium with the machine on which it is running. p0f can also assist in analyzing other aspects of the remote system. Basically, it is a  tool used to perform a forensic investigation of a system that has been compromised or is under attack. Using this tool, you can analyze the structure of TCP/IP packets to determine OS and other configurations of the target host. Let's check how to do this.step 1 - Open Linux Terminal and type p0fStep 2 - Explore your target host using any browserOnce the connection is established with the target host, the client will start to interact with the server.You can see that my client IP 10.0.2.15 has established a connection with the target web server 72.163.4.185 using port 80.How to prevent Footprinting?Your every move, each activity, or data available on the internet is a potential footprint that can open layers of information for attackers.Now let's discuss preventive steps to avoid threats and reduce the security risk of the organization and individual.1. Delete or De-activate old accountsOnce your account is assigned online, it can be shared anywhere with your full name, email address, pictures, location, and other information. Official email accounts provided to the employees are also available online. Once the employee has left the organization, the email account must be deleted to avoid fraudulent transactions using the same.  2. Unsubscribe from unwanted mailsAll of us keep subscribing to newsletters, events registrations, offers and to many other mail lists. While some of these lists may be useful, most of them result in unnecessary clutter in our mailbox. Unsubscribe to all unnecessary emails so that you can reduce your digital footprinting on the internet.  3. Use stealth modeThere are many browsers which help you to surf with privacy. This is how you can search online with ease and avoid websites from tracking your interests, location, etc. Using browsers like TOR, Duck Duck Go with some advance settings in your regular browser can restrict the sharing of your information online.4. Use a VPNThere are many VPNs, or Virtual Private Networks, available that you can use for privacy.  A VPN provides you with an extra layer of security to protect your privacy over the internet. This will prevent others from tracking your web activity and being able to collect data by watching your surfing patterns.5. SEOPrevent search engines from crawling through your cached webpages and user anonymous registration details, and minimize unwanted footprints.6. Configure Web serversConfigure your web servers to avoid information leakage and block all unwanted protocols to prevent any unethical external scans. Use TCP/IP and IPSec Protocols.  Always maintain a separation between the internal and external DNS.7.  Do it yourselfPerform footprinting techniques as we have discussed above and do a check to see whether any sensitive or unwanted information of yours is available on the internet. Use the OSINT framework to delve deeper, and remove posted/ shared data that reveals any kind of sensitive information which can be a potential threat. Share tips and tricks to avoid fraud calls and social engineering.What is ReconnaissanceSimilar to footprinting, Reconnaissance is a very important stage in the initial hacking process. In this stage, attackers gather information, much like a detective does! This process involves gathering information about the target flaws, vulnerabilities that can be used in penetration testing, and the beginning of any data breaches.Any information gathered about the target may be a crucial piece of the jigsaw, needed to reveal the critical vulnerabilities of the target.What critical information can be revealed in the reconnaissance phase?1) Network InformationIP addressessubnet masknetwork topologydomain names2) Host Informationuser- namesgroup namesarchitecture typeoperating system family and versionTCP and UDP services running with versions3) Security Policiespassword complexity requirementspassword change frequencyexpired/disabled account retentionphysical security (e.g. access badges, door locks, etc.)firewallsintrusion detection systems4) Personnel detailsdesignationstelephone numbersocial hangoutscomputer skillsThere are two types of reconnaissance.1. Passive reconnaissanceThis is when the attacker gathers information about the target through openly available sources. There are multiple sources available free on the internet which may provide a blueprint of the organization or individual.2. Active reconnaissanceHere, the attacker directly interacts with the target's computer system to gain information using scanning, eavesdropping, and packet capturing techniques. The advantage of active reconnaissance is that the collected information is quite accurate and relevant; however, there is a risk of getting detected.Netcat, Nmap are the best tools for this.What is Enumeration?Once an attacker creates an active connection with the target, they are able to perform directed queries to gain more information. For example,UsernameshostnamesIP addressPasswords (or strength)configurationThe information gathered about the target can be used to identify vulnerabilities in the target system. Once an attacker gains this information, they can steal private data and sometimes, even worse, change the configuration.Types of EnumerationThere are multiple types of enumeration.

If the name server allows transfer by any other unauthorized user than all DNS names and IP addresses hosted by the name server will return in ASCII Test.Some of the tools that can be for this include nslookup, maltego, dnenum,  dnsrecon, etc.Here is an example that uses nslookup.NSlookup queries DNS servers for machine names and addresses.For example, if we want to find the IP address of Google's web server by entering nslookup, we will enter the below command.nslookup www.google.comand then the output will be like this.C:\>nslookup www.google.com Server:  dnsr1.sbcglobal.net Address:  68.94.156.1 Non-authoritative answer: Name:    www.1.google.com Addresses:  64.233.187.99, 64.233.187.104 Aliases:  www.google.comThe first two lines of output tell us which DNS servers are being queried. In this case, it’s dnsr1.sbcglobal.net in Texas. The non-authoritative answer lists two IP addresses for the Google web servers.Responses from non-authoritative servers do not contain copies of any domains. They have a cache file that is constructed from all the DNS lookups it has performed in the past, for which it has received an authoritative response.In the interactive mode, the user will be given a prompt of >; at which point, the user can enter a variety of options, including attempts to perform a zone transfer.The hackers can enumerate other information like network resources and sharing, routing tables, machine names, applications and banners, users, and groups, etc.There are other types of enumeration.Windows enumerationLinux enumerationLDAP enumerationNetBios enumeration  SNMP enumerationNTP enumeration etc.Steps to prevent enumeration.Use centralized network administration contact details in the NIC (Network Information Center) database to prevent social engineering against IT departments.Configure Name servers to disable DNS zone transfer for untrusted hosts.Configure web servers to prevent indexing of directories without index files and avoid keeping sensitive files and documents on publicly accessible hosts like FTP, HTTP, etc.Configure SMTP servers to ignore emails from unknown recipients.Disable SMBUse NTLM or basic authentication to limit access for authorized users only.Implement the group policy security option named "access restrictions for anonymous connections."ConclusionIn this article, you have learned about the initial steps involved in hacking, during the pre-attack phase, including information gathering, scanning, and mapping the network.The more information the hacker is able to gather, the higher are their chances of a successful attack.

Introduction to Footprinting and Reconnaissance in Ethical Hacking

Footprinting is one of the most convenient ways for hackers to collect information about targets such as computer systems, devices, and networks. Using this method, hackers can unravel information on open ports of the target system, services running, and remote access probabilities.

Since it is the initial phase of hacking it is really important to develop an accurate understanding of the entire process. The systematic footprinting of a target enables the attacker to get a blueprint of the target's security posture.

In this article, we will get to know how malicious hackers perform footprinting on the organization or target's system, what all they can do, and how it will be harmful to businesses and individuals. On the other hand, white hat hackers who are well versed in footprinting will be able to improve the security of the organizations they work for. With systematic methodology, businesses can identify their vulnerabilities so they can patch and make changes in policy accordingly.

Types of footprinting:

  • Who is footprinting
  • Network footprinting
  • DNS footprinting
  • Competitive intelligence
  • Email footprinting
  • Website footprinting
  • Social Engineering
  • Google Hacking

How to perform footprinting?

Footprinting is the first step, during which the hacker gathers as much information as possible to find ways to enter a target system. For successful footprinting, the attacker needs to first check the visibility of the target and see how to gather related information on the internet through open sources. Through careful analysis, the attacker can determine the scope of potential entry points. The following information can be collected:

  • Company names
  • Domain names
  • Business subsidiaries  
  • IP Addresses
  • Business emails  
  • Network phone numbers  
  • Key employees

and so on.

In hacking terms, we can call it the "Front Door" of the castle on target.  

The first step of footprinting is to determine what to attack to obtain the "footprint" of the target network which includes, but is not limited to the following:

  • Hostnames
  • Network address ranges
  • Exposed hosts  
  • Exposed applications  
  • OS and its versions
  • Application and its versions

and many more.

Apart from this, the attackers have to decide the scope of the target with regards to the entire organization or certain subsidiaries or locations. Based on the scope, they start to dig deep into the information like company web-pages, related organizations, employee details, contacts, e-mail addresses, currents events, locations, news, policies, disgruntled employees, mergers, acquisitions, or events to garner some clues, opportunities, and contacts for attackers.

Methods of footprinting

1. Port Scanning

Port scanners are used to determine live hosts on the internet and find out which Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) ports are listening on each system, as well as which operating system is installed on the host. To identify the relationship of each host and potential security mechanisms between the attacker and targets, they use traceroutes.

Tools:

  • NSLookup - to perform DNS queries and zone transfers
  • Tracert - to create network maps of the target.

Once port scanning and trace routing are done, attackers will create a network map that represents the target's internet footprinting.

2. Google Hacking

Despite what you may infer from the name, this method does not involve hacking Google! This is a means by which you can collect information from the Google search engine in a smart way.

Search engines have many features using which you can get uncommon, but very specific search results from the internet. Using these techniques, hackers and attackers perform a search using advanced operators, examples of which are given below.

Introduction to Footprinting and Reconnaissance in Ethical Hacking

These types of operators can uncover much sensitive information that can potentially harm the target and should therefore not be revealed.

Let's take an example. 

Go to google.com and paste this- allinurl:tsweb/default.htm

You will get more than 200 websites that have tsweb/default folder. Using this, the hacker gets a chance to get into the organization's servers. This is just one example. There is plenty of such information about targets available online, which hackers can take advantage of.

3. Ping Sweep

If the attacker wants to know which are the machines on your network that are currently live, they can perform a ping sweep. Ping uses ICMP packets to send echo requests to the target system,  and waits for an echo reply. If the device is not reachable, it will show a "request time out"; but if the device is online and not restricted from responding, it will send an echo reply back. Here are some tools used to perform ping sweeps through a range of devices that determine the active devices on the target network.

  • Nmap
  • Angry IP scanner
  • Super Scan  
  • Pinger etc.

4.  Who is lookup

This method can be used to collect basic database queries like domain name, IP Address block, location, and much more information about the organization.

Introduction to Footprinting and Reconnaissance in Ethical Hacking

Example of Footprinting

Let's see an example of footprinting using the Linux tool p0f.

p0f is a passive TCP/IP stack fingerprinting tool to identify the system running on machines that send network traffic to the box it is running on, or to a machine that shares a medium with the machine on which it is running. p0f can also assist in analyzing other aspects of the remote system. Basically, it is a  tool used to perform a forensic investigation of a system that has been compromised or is under attack. Using this tool, you can analyze the structure of TCP/IP packets to determine OS and other configurations of the target host. Let's check how to do this.

  • step 1 - Open Linux Terminal and type p0f
  • Step 2 - Explore your target host using any browser

Once the connection is established with the target host, the client will start to interact with the server.

Introduction to Footprinting and Reconnaissance in Ethical Hacking

You can see that my client IP 10.0.2.15 has established a connection with the target web server 72.163.4.185 using port 80.

How to prevent Footprinting?

Your every move, each activity, or data available on the internet is a potential footprint that can open layers of information for attackers.

Now let's discuss preventive steps to avoid threats and reduce the security risk of the organization and individual.

1. Delete or De-activate old accounts

Once your account is assigned online, it can be shared anywhere with your full name, email address, pictures, location, and other information. Official email accounts provided to the employees are also available online. Once the employee has left the organization, the email account must be deleted to avoid fraudulent transactions using the same.  

2. Unsubscribe from unwanted mails

All of us keep subscribing to newsletters, events registrations, offers and to many other mail lists. While some of these lists may be useful, most of them result in unnecessary clutter in our mailbox. Unsubscribe to all unnecessary emails so that you can reduce your digital footprinting on the internet.  

3. Use stealth mode

There are many browsers which help you to surf with privacy. This is how you can search online with ease and avoid websites from tracking your interests, location, etc. Using browsers like TOR, Duck Duck Go with some advance settings in your regular browser can restrict the sharing of your information online.

4. Use a VPN

There are many VPNs, or Virtual Private Networks, available that you can use for privacy.  A VPN provides you with an extra layer of security to protect your privacy over the internet. This will prevent others from tracking your web activity and being able to collect data by watching your surfing patterns.

5. SEO

Prevent search engines from crawling through your cached webpages and user anonymous registration details, and minimize unwanted footprints.

6. Configure Web servers

Configure your web servers to avoid information leakage and block all unwanted protocols to prevent any unethical external scans. Use TCP/IP and IPSec Protocols.  Always maintain a separation between the internal and external DNS.

7.  Do it yourself

Perform footprinting techniques as we have discussed above and do a check to see whether any sensitive or unwanted information of yours is available on the internet. Use the OSINT framework to delve deeper, and remove posted/ shared data that reveals any kind of sensitive information which can be a potential threat. Share tips and tricks to avoid fraud calls and social engineering.

What is Reconnaissance

Similar to footprinting, Reconnaissance is a very important stage in the initial hacking process. In this stage, attackers gather information, much like a detective does! This process involves gathering information about the target flaws, vulnerabilities that can be used in penetration testing, and the beginning of any data breaches.

Any information gathered about the target may be a crucial piece of the jigsaw, needed to reveal the critical vulnerabilities of the target.

What critical information can be revealed in the reconnaissance phase?

1) Network Information

  • IP addresses
  • subnet mask
  • network topology
  • domain names

2) Host Information

  • user- names
  • group names
  • architecture type
  • operating system family and version
  • TCP and UDP services running with versions

3) Security Policies

  • password complexity requirements
  • password change frequency
  • expired/disabled account retention
  • physical security (e.g. access badges, door locks, etc.)
  • firewalls
  • intrusion detection systems

4) Personnel details

  • designations
  • telephone number
  • social hangouts
  • computer skills

There are two types of reconnaissance.

1. Passive reconnaissance

This is when the attacker gathers information about the target through openly available sources. There are multiple sources available free on the internet which may provide a blueprint of the organization or individual.

2. Active reconnaissance

Here, the attacker directly interacts with the target's computer system to gain information using scanning, eavesdropping, and packet capturing techniques. The advantage of active reconnaissance is that the collected information is quite accurate and relevant; however, there is a risk of getting detected.

Netcat, Nmap are the best tools for this.

What is Enumeration?

Once an attacker creates an active connection with the target, they are able to perform directed queries to gain more information. For example,

  • Usernames
  • hostnames
  • IP address
  • Passwords (or strength)
  • configuration

The information gathered about the target can be used to identify vulnerabilities in the target system. Once an attacker gains this information, they can steal private data and sometimes, even worse, change the configuration.

Types of Enumeration

There are multiple types of enumeration. Let’s take a look at one example.

DNS Enumeration

DNS enumeration is the technique employed to find all the DNS servers and their corresponding records for an organization. A list of DNS records provides an overview of database records.

DNS zone transfer will allow replication of DNS data or DNS files. The user will perform a DNS zone transfer query from the name server. If the name server allows transfer by any other unauthorized user than all DNS names and IP addresses hosted by the name server will return in ASCII Test.

Some of the tools that can be for this include nslookup, maltego, dnenum,  dnsrecon, etc.

Here is an example that uses nslookup.

NSlookup queries DNS servers for machine names and addresses.

For example, if we want to find the IP address of Google's web server by entering nslookup, we will enter the below command.

nslookup www.google.com

and then the output will be like this.

C:\>nslookup www.google.com
Server:  dnsr1.sbcglobal.net
Address:  68.94.156.1
Non-authoritative answer:
Name:    www.1.google.com
Addresses:  64.233.187.99, 64.233.187.104
Aliases:  www.google.com

The first two lines of output tell us which DNS servers are being queried. In this case, it’s dnsr1.sbcglobal.net in Texas. The non-authoritative answer lists two IP addresses for the Google web servers.

Responses from non-authoritative servers do not contain copies of any domains. They have a cache file that is constructed from all the DNS lookups it has performed in the past, for which it has received an authoritative response.

In the interactive mode, the user will be given a prompt of >; at which point, the user can enter a variety of options, including attempts to perform a zone transfer.

The hackers can enumerate other information like network resources and sharing, routing tables, machine names, applications and banners, users, and groups, etc.

There are other types of enumeration.

  • Windows enumeration
  • Linux enumeration
  • LDAP enumeration
  • NetBios enumeration  
  • SNMP enumeration
  • NTP enumeration etc.

Steps to prevent enumeration.

  1. Use centralized network administration contact details in the NIC (Network Information Center) database to prevent social engineering against IT departments.
  2. Configure Name servers to disable DNS zone transfer for untrusted hosts.
    Configure web servers to prevent indexing of directories without index files and avoid keeping sensitive files and documents on publicly accessible hosts like FTP, HTTP, etc.
  3. Configure SMTP servers to ignore emails from unknown recipients.
  4. Disable SMB
  5. Use NTLM or basic authentication to limit access for authorized users only.
    Implement the group policy security option named "access restrictions for anonymous connections."

Conclusion

In this article, you have learned about the initial steps involved in hacking, during the pre-attack phase, including information gathering, scanning, and mapping the network.

The more information the hacker is able to gather, the higher are their chances of a successful attack. If you increase your security right from the initial phase, it will reduce the possibilities for an attacker to get into your system. By controlling your digital footprint, you can increase your security posture and keep your data safe from hackers.

Learning Ethical Hacking Can Be A Disaster If You Neglect These 7 Rules

Attacking one’s own self defence systems to check for vulnerabilities was considered to be a major war strategy even 1500 years ago. Attacking one’s own systems to check for resilience against attacks may have helped many of our ancestors win wars by fortifying their weak spots. The trend continues to this day in the name of ‘ethical hacking’ where in vulnerabilities in cyber systems are sniffed out and systems are fortified against attacks. A new kind of battle is being waged upon us this day, not in the battlefield but in the digital world. Cybercrime is the fastest growing area of crime and nobody is safe. The internet has brought a lot of anonymity to its users and hackers and cyber criminals take advantage of this anonymity to perpetrate crime. Ethical hacking was created out of a need to proactively counter cyber threat, and improve defences to protect the interests of vulnerable parties. Ethical Hacking is big business today. Google, Facebook, Twitter and other big companies spend millions on ‘white hat hacking’ to sniff out vulnerabilities in their systems. Bug bounty programs, where hackers will be compensated for reporting vulnerabilities, will be a norm in the future. Organizations trust individuals who have been certified as Ethical Hackers as they are aware of the code of conduct to be followed during ethical hacking courses. But even the sincerest ethical hacker may stumble and get into situations that may harm the hacker or the organization. Even certified ethical hackers need to understand some rules before practising white hat hacking. • You are a white hat hacker but you still need permission before hacking into a user’s system: White hat hacking may be ethical but hacking into a user’s system without explicit permission from them will land you in trouble. In fact hacking, even for ethical purposes without explicit permission from the owners is a criminal offence in most countries. • Understand your client’s business and organizational set up: Before you start off on ethical hacking it is important that you understand your client organisation’s business and system. This will give you a background on the sensitivities of their network and how you need to handle any sensitive information that you might encounter. • Do not exceed limits imposed by the client: Even if your client has given you full access to their network, there might still be a limit to how much you can dig. Do not dig deeper than you have been told to as you might be breaching client trust. • Make sure you do your job properly so that you do not compromise the client’s defence systems: Your job is to sniff out holes and ensure that those holes are fixed to strengthen the IT security system. Give a detailed report of your findings and ensure that you do not overstep any limits or violate any laws or regulations.Plan out before you perform ethical hacking tests as time and patience are of utmost importance for sensitive results. • Be transparent with your clients: Open communication with your client will not only help your client but also you, by increasing your trustworthiness. You must disclose all discoveries that you have made to your client so that they can take necessary precautions to safeguard their systems. Your client should be aware of what’s going on at all times. • Be confidential and ethical: You should maintain confidentiality during and even after the job is done. You are an ethical hacker and work ethics come topmost for you and this includes client confidentiality. Disclosing secrets of your clients to third parties will defeat the very purpose of ethical hacking. Uphold the values and goals of the company and respect their privacy. • Cover your tracks: You have penetrated the systems and you have suggested detailed clean-ups. But as you exit, you must ensure that you do not leave any footprints and thus protect the system from future attacks. Ethical hacking is a sensitive and sometimes dangerous job. But every ethical hacker must follow the commandments of ethical hacking as there is a very thin line between black hat and white hat hacking. Stay focused and true to yourself and you will be successful
