nmap

Nmap is a powerful network scanner used to identify systems and services. nmap was originally developed with network security in mind, it is a tool that was designed to find vulnerabilities within a network. nmap is more than just a simple port scanner though, you can use nmap to find specific versions of services, certain OS types, or even find that pesky printer someone put on your network without telling you.

nmap can be used for good and for evil, today we will cover some common situations where nmap makes life easier for sysadmins which is generally good. Even if some Sysadmins are evil…

Discover IP’s in a subnet (no root)

 $ nmap -sP 192.168.0.0/24
 Starting Nmap 7.30 ( http://nmap.org ) at 2016-10-12 21:12 GMT
 Nmap scan report for 192.168.0.1
 Host is up (0.0013s latency).
 Nmap scan report for 192.168.0.92
 Host is up (0.0032s latency).
 Nmap scan report for 192.168.0.113
 Host is up (0.0011s latency).

This is one of the simplest uses of nmap. This command is commonly refereed to as a “ping scan”, and tells nmap to send an icmp echo request, TCP SYN to port 443, TCP ACK to port 80 and icmp timestamp request to all hosts in the specified subnet. nmap will simply return a list of ip’s that responded. Unlike many nmap commands this particular one does not require root privileges, however when executed by root nmap will also by default send arp requests to the subnet.

Scan for open ports (no root)

 $ nmap 192.168.0.0/24
 Starting Nmap 7.30 ( http://nmap.org ) at 2016-10-12 21:20 GMT
Nmap scan report for 192.168.0.1 Host is up (0.0043s latency). Not shown: 998 closed ports PORT STATE SERVICE 80/tcp open http 443/tcp open https 

This scan is the default scan for nmap and can take some time to generate. With this scan nmap will attempt a TCP SYN connection to 1000 of the most common ports as well as an icmp echo request to determine if a host is up. nmap will also perform a DNS reverse lookup on the identified ip’s as this can sometimes be useful information.

Identify the Operating System of a host (requires root)

 # nmap -O 192.168.0.164
 Starting Nmap 7.30 ( http://nmap.org ) at 2016-10-12 21:35 GMT
 Nmap scan report for 192.168.0.112
 Host is up (0.00032s latency).
 Not shown: 996 closed ports
 PORT STATE SERVICE
 88/tcp open kerberos-sec
 139/tcp open netbios-ssn
 445/tcp open microsoft-ds
 631/tcp open ipp
 MAC Address: 00:00:00:00:00:00 (Unknown)
 Device type: general purpose
 Running: Apple Mac OS X 10.5.X
 OS details: Apple Mac OS X 10.5 - 10.6 (Leopard - Snow Leopard) (Darwin 9.0.0b5 - 10.0.0)
 Network Distance: 1 hop

With the -O option nmap will try to guess the targets operating system. This is accomplished by utilizing information that nmap is already getting through the TCP SYN port scan. This is usually a best guess but can actually be fairly accurate. The operating system scan however does require root privileges.

Identify Hostnames (no root)

 $ nmap -sL 192.168.0.0/24
 Starting Nmap 7.30 ( http://nmap.org ) at 2016-10-12 21:35 GMT
 Nmap scan report for 192.168.0.0
 Nmap scan report for router.local (192.168.0.1)
 Nmap scan report for fake.local (192.168.0.2)
 Nmap scan report for another.fake.local (192.168.0.3)

This is one of the most subtle commands of nmap, the -sL flag tells nmap to do a simple DNS query for the specified ip. This allows you to find hostnames for all of the ip’s in a subnet without having send a packet to the individual hosts themselves.

Hostname information can tell you a lot more about a network than you would think, for instance if you labeled your Active Directory Servers with ads01.domain.com you shouldn’t be surprised if someone guesses its use.

TCP Syn and UDP Scan (requires root)

 # nmap -sS -sU -PN 192.168.0.164
 Starting Nmap 7.30 ( http://nmap.org ) at 2016-10-12 21:12 GMT
 Nmap scan report for 192.168.0.112
 Host is up (0.00029s latency).
 Not shown: 1494 closed ports, 496 filtered ports
 PORT STATE SERVICE
 88/tcp open kerberos-sec
 139/tcp open netbios-ssn
 445/tcp open microsoft-ds
 631/tcp open ipp
 88/udp open|filtered kerberos-sec
 123/udp open ntp
 137/udp open netbios-ns
 138/udp open|filtered netbios-dgm
 631/udp open|filtered ipp
 5353/udp open zeroconf

The TCP SYN and UDP scan will take a while to generate but is fairly unobtrusive and stealthy. This command will check about 2000 common tcp and udp ports to see if they are responding. When you use the -Pn flag this tells nmap to skip the ping scan and assume the host is up. This can be useful when there is a firewall that might be preventing icmp replies.

TCP SYN and UDP scan for all ports (requires root)

 # nmap -sS -sU -PN -p 1-65535 192.168.0.164
 Starting Nmap 7.30 ( http://nmap.org ) at 2016-10-12 21:36 GMT
 Nmap scan report for 192.168.0.112
 Host is up (0.00021s latency).
 Not shown: 131051 closed ports
 PORT STATE SERVICE
 88/tcp open kerberos-sec
 139/tcp open netbios-ssn
 445/tcp open microsoft-ds
 631/tcp open ipp
 17500/tcp open unknown
 88/udp open|filtered kerberos-sec
 123/udp open ntp
 137/udp open netbios-ns
 138/udp open|filtered netbios-dgm
 631/udp open|filtered ipp
 5353/udp open zeroconf
 17500/udp open|filtered unknown
 51657/udp open|filtered unknown
 54658/udp open|filtered unknown
 57798/udp open|filtered unknown
 58488/udp open|filtered unknown
 60027/udp open|filtered unknown

This command is the same as above however by specifying the full port range from 1 to 65535 nmap will scan to see if the host is listening on all available ports. You can use the port range specification on any scan that performs a port scan.

TCP Connect Scan (no root)

 $ nmap -sT 192.168.0.164
 Starting Nmap 7.30 ( http://nmap.org ) at 2016-10-12 21:40 GMT
 Nmap scan report for 192.168.0.112
 Host is up (0.0015s latency).
 Not shown: 964 closed ports, 32 filtered ports
 PORT STATE SERVICE
 88/tcp open kerberos-sec
 139/tcp open netbios-ssn
 445/tcp open microsoft-ds
 631/tcp open ipp

This command is similar to the TCP SYN scan however rather than sending a SYN packet and reviewing the headers it will ask the OS to establish a TCP connection to the 1000 common ports.

Aggressively Scan Hosts (no root)

 $ nmap -T4 -A 192.168.0.0/24
 Nmap scan report for 192.168.0.67
 Host is up (0.00060s latency).
 Not shown: 996 closed ports

Unlike some of the earlier commands this command is very aggressive and very obtrusive. The -A simply tells nmap to perform OS checking and version checking. The -T4 is for the speed template, these templates are what tells nmap how quickly to perform the scan. The speed template ranges from 0 for slow and stealthy to 5 for fast and obvious.

Fast Scan (no root)

 $ nmap -T4 -F 192.168.0.138
 Starting Nmap 7.30 ( http://nmap.org ) at 2016-10-12 21:48 GMT
 Nmap scan report for 192.168.0.112

 Not shown: 96 closed ports
 PORT STATE SERVICE
 88/tcp open kerberos-sec
 139/tcp open netbios-ssn
 445/tcp open microsoft-ds
 631/tcp open ipp

This scan limits the scan to the most common 100 ports, if you simply want to know some potential hosts with ports open that shouldn’t be this is a quick and dirty command to use.

By adding verbose to a majority of the commands above you get a better insight into what nmap is doing; for some scans verbosity will provide additional details that the report does not provide.
While these are 10 very useful nmap commands I am sure there are some more handy nmap examples out there. If you have one to add to this list feel free to drop it into a comment.

Performing a nMap Scan

Researchers have disclosed a critical zero-day vulnerability in the JPEG 2000 image file format parser implemented in OpenJPEG library, which could allow an attacker to remotely execute arbitrary code on the affected systems.

Discovered by security researchers at Cisco Talos group, the zero-day flaw, assigned as TALOS-2016-0193/CVE-2016-8332, could allow an out-of-bound heap write to occur that triggers the heap corruption and leads to arbitrary code execution.

OpenJPEG is an open-source JPEG 2000 codec. Written in C language, the software was developed for coding and encoding JPEG2000 images, a format that is often used for tasks like embedding image files within PDF documents through popular software including PdFium, Poppler, and MuPDF.Hackers can exploit the security vulnerability by tricking the victim into opening a specially crafted, malicious JPEG2000 image or a PDF document containing that malicious file in an email.
The hacker could even upload the malicious JPEG2000 image file to a file hosting service, like Dropbox or Google Drive, and then send that link to the victim.
Once downloaded to the system, it would create a way for hackers to remotely execute malicious code on the affected system.The flaw was caused “due to an error while parsing mcc records in the jpeg2000 file,…resulting in an erroneous read and write of adjacent heap area memory,” Cisco explained in its advisory.

Careful manipulation of heap layout and can lead to further heap metadata process memory corruption ultimately leading to code execution under attacker control.“The researchers successfully tested the JPEG 2000 image exploit on the OpenJPEG openjp2 version 2.1.1. The flaw was discovered by Aleksandar Nikolic from the Cisco Talos Security team.

The team reported the zero-day flaw to OpenJPEG developers in late July, and the company patched the flaw last week with the release of version 2.1.2.

The vulnerability has been assigned a CVSS score of 7.5, categorizing it as a high-severity bug.

KickassTorrent went down, The Pirate Bay and Extra Torrent were the Kings of the Piracy World, However, the recent developments have resulted in the seizure of KickassTorrents’ primary domains and the arrest of its 30-year-old founder.

Before Kickass Torrent went Down, it was the world’s biggest torrent site with more than 50 Million unique visitors and 69 worldwide Alexa rank. When the Kickass Torrent went down this news was breaking the internet, After the seized of Kickass Torrent domains, we have seen the advent of multiple KickassTorrents mirrors and a new community formed by its original staffers, the original pirate website is nowhere to be seen.

Now the torrent users have now started looking for the best KickassTorrents alternatives. Talking about such website, The Pirate Bay looks like the biggest alternative.

It’s interesting to note that The Pirate Bay faced a similar experience back in 2014 when it went offline for a month. Then, TPB users flocked to KAT.

Expressing the support, a TBP staffer told TF:

“When both TPB and its forum went down, we had overwhelming support from KAT users on their forum, and our staff were able to keep the communities updated on important news and announcements.”
The Pirate Bay hopes that Kickass Torrent will be back and its loyal users and the loyal community will be there to support Kickass Torrent and will help to make it work again.

Now here it’s come the second largest Kickass Torrent alternative, Extra Torrent is one of the biggest torrent website in the world.

Just like Kickass Torrent, Extra Torrent has very good community and a really big range of torrents. ET is becoming the second big choice for users, After Kat.cr went down ET’s signup getting boost up with 200% and traffic increased by 300%.

“So far we got 200% signup, and 300% traffic increase at ExtraTorrent,” said SaM, the operator of ET. It is sad to see an iconic site go this way, and it shows how the torrent community is targeted by all means. But, I guess torrenting will prevail and this doesn’t mean the death or end of this era.”

TV failureInfoSec skills are in such high demand right now. As the world continues to turn everything into an app and connect even the most basic devices to the internet, the demand is only going to grow, so it’s no surprise everyone wants to learn hacking these days.

However, almost every day I come across a forum post where someone is asking where they should begin to learn hacking or how to practice hacking. I’ve compiled this list of some of the best hacking sites to hopefully be a valuable resource for those wondering how they can build and practice their hacking skill set. I hope you find this list helpful, and if you know of any other quality hacking sites, please let me know in the comments, so I can add them to the list.

1.CTF365:
On CTF365 users build and defend their own servers while launching attacks on other users’ servers. The CTF365 training environment is designed for security professionals who are interested in training their offensive skills or sysadmins interested in improving their defensive skills. If you are a beginner to infosec, you can sign up for a free beginner account and get your feet wet with some pre-configured vulnerable servers.

2. OVERTHEWIRE:
OverTheWire is designed for people of all experience levels to learn and practice security concepts. Absolute beginners are going to want to start on the Bandit challenges because they are the building blocks you’ll use to complete the other challenges.

3. HACKING-LAB:
Hacking-Lab provides the CTF challenges for the European Cyber Security Challenge, but they also host ongoing challenges on their platform that anyone can participate in. Just register a free account, setup vpn and start exploring the challenges they offer.

4. PWNABLE.KR:
pwnable.kr focuses on ‘pwn’ challenges, similar to CTF, which require you find, read and submit ‘flag’ files corresponding to each challenge. You must use some sort of programming, reverse-engineering or exploitation skill to access the content of the files before you are able to submit the solution.

They divide up the challenge into 4 skill levels: Toddler’s Bottle, Rookiss, Grotesque and Hacker’s Secret. Toddler’s Bottle are very easy challenges for beginners, Rookiss is rookie level exploitation challenges, Grotesque challenges become much more difficult and painful to solve and, finally, Hacker’s Secret challenges require special techniques to solve.

5. IO:
IO is a wargame from the createors of netgarage.org, a community project where like-minded people share knowledge about security, AI, VR and more. They’ve created 3 versions, IO, IO64 and IOarm, with IO being the most mature. Connect to IO via SSH and you can begin hacking on their challenges.

6. SMASHTHESTACK:
SmashTheStack is comprised of 7 different wargames – Amateria, Apfel (currently offline), Blackbox, Blowfish, CTF (currently offline), Logic and Tux. Every wargame has a variety of challenges ranging from standard vulnerabilities to reverse engineering challenges.

7. MICROCORRUPTION:
Microcorruption is an embedded security CTF where you have to reverse engineer fictional Lockitall electronic lock devices. The Lockitall devices secure the bearer bounds housed in warehouses owned by the also fictional Cy Yombinator company. Along the way you’ll learn some assembly, how to use a debugger, how to single step the lock code, set breakpoints, and examine memory all in an attempt to steal the bearer bonds from the warehouses.

8. REVERSING.KR:
reversing.kr has 26 challenges to test your cracking and reverse engineering abilities. The site hasn’t been updated since the end of 2012, but the challenges available are still valuable learning resources.

9. HACK THIS SITE:
Hack This Site is a free wargames site to test and expand your hacking skills. It features numerous hacking missions across multiple categories including Basic, Realistic, Application, Programming, Phonephreaking, JavaScript, Forensic, Extbasic, Stego and IRC missions. It also boasts a large community with a large catalog of hacking articles and a forum for to have discussions on security related topics. Finally, they’ve recently announced they are going to be overhauling the dated site and codebase, so expect some big improvements in the coming months.

10. W3CHALLS:
W3Challs is a pentesting training platform with numerous challenges across different categories including Hacking, Cracking, Wargames, Forensic, Cryptography, Steganography and Programming. The aim of the platform is to provide realistic challenges, not simulations and points are awarded based on the difficulty of the challenge (easy, medium, hard). There’s a forum where you can discuss and walkthrough the challenges with other members.

11. PWN0:
pwn0 is the VPN where (almost) anything goes. Go up against pwn0bots or other users and score points by gaining root on other systems.

12. EXPLOIT EXERCISES:
Exploit Exercises provides a variety of virtual machines, documentation and challenges that can be used to learn about a variety of computer security issues such as privilege escalation, vulnerability analysis, exploit development, debugging, reverse engineering, and general cyber security issues.

13. RINGZER0 TEAM ONLINE CTF:
RingZer0 Team Online CTF offers a ton of challenges, 234 as of this post, that will test your hacking skills across multiple categories including Cryptography, Jail Escaping, Malware Analysis, SQL Injection, Shellcoding and more. After you successfully complete a challenge, you can write up your solution and submit it to the RingZer0 Team. If your write up is accepted, you’ll earn RingZer0Gold which can be exchanged for hints during future challenges.

14. HELLBOUND HACKERS:
Hellbound Hackers offers traditional exploit challenges, but they also offer some challenges that others don’t such as web and app patching and timed challenges. The web and app patching challenges have you evaluating a small snippet of code, identifying the exploitable line of code and suggesting a the code to patch it. The timed challenges have the extra constraint of solving the challenge in a set amount of time. I thought these two categories were a cool differentiator from most other CTF sites.

15. TRY2HACK:
Try2Hack provides several security oriented challenges for your entertainment and is one of the oldest challenge sites still around. The challenges are diverse and get progressively harder.

16. HACK.ME:
Hack.me is a large collection of vulnerable web apps for practicing your offensive hacking skills. All vulnerable web apps are contributed by the community and each one can be run on the fly in a safe, isolated sandbox.

17. HACKTHIS!!:

How Ping of Death attack works?
Not all computers can handle data larger than a fixed size. So, when a ping of death packet is sent from a source computer to a target machine, the ping packet gets fragmented into smaller groups of packets.

One fragment is of 8 octets size. When these packets reach the target computer, they arrive in fragments. So, the target computer reassembles the malformed packets which are received in chunks. But, the whole assembled packet causes buffer overflow at the target computer.

This buffer flow often causes the system crash making the system more vulnerable to attack.

Once the system becomes more vulnerable to attack, it allows more attacks like the injection of a trojan horse on the target machine.

A simple tutorial on how to perform DoS attack using ping of death using CMD:

Disclaimer: This is just for educational purposes. It’s nothing great but you can use it to learn.

Here are the steps:

  • Open Notepad
  • Copy the following text on the notepad

:loop
ping <IP Address> -l 65500 -w 1 -n 1
goto :loop

In the above command, replace <IP Address> with an IP address.

  • Save the Notepad with any name. Let’s say dos.txt
  • Right click on the dos.txt and click on rename.
  • Change the extension from .txt to .bat
  • So, now the file name should be dos.bat
  • Double click on it and you will see a command prompt running with a lot of pings.

WordPress is the most popular Content Management System (CMS) used to power digital assets of websites and blogs on the Internet.

In fact, about 75 million sites (representing about 26% of all sites) depend on WordPress to make their online presence known.

Because of its increasing popularity, WordPress powered platforms are normally targeted by malicious hacking attacks and other types of security vulnerabilities.

In early 2016, Wordfence, a site providing security plugin for WordPress users, reported over 6 million password attacks  targeting over 72,000 individual sites within a 16-hour period.

And, what’s the most vulnerable point in the security of any WordPress site?

Yes, you are right, it’s the P A S S W O R D.

If an unauthorized person is able to guess, crack, or retrieve your password, then you could be in for a long, very long day.

Currently, with the modern advancement in technology, password-cracking techniques have equally become better. Some passwords could be very easy for a computer to break and strenuous for a person to keep in memory or type.

One of the most advanced password cracking tools can attempt up to 350 billion password guesses every second.

So, creating unbreakable passwords is key to maintaining the security of your blog.

Here are some useful tips.

  1. Keep away from the world’s worst passwords

In the current digital age, having a password to access your online accounts is simply indispensable.

SplashData, which focuses on making password management software, compiled a list of commonly used passwords among Internet users. The company analyzed the data from more than 2 million passwords retrieved in 2015.

If this list contains the password or its related combinations you use for accessing your WordPress site, then move swiftly to a more secure one.

Here is a list of the 25 commonly used passwords:

Keep away from the world’s worst passwords

  1. Use a unique and creative password for your WordPress site

Do not make the fatal mistake of using the same password for your email account, social media accounts, and other places for accessing your WordPress website or blog.

Regurgitating your passwords is a risky affair you should avoid as plague. In case a malicious hacker discovers the password you use for one account, he or she could simply make your online life unbearable.

Desist from using names of places and dictionary words in your passwords. Currently, the methods of cracking passwords have advanced such that hackers are able to “brute force“; that is, try out different dictionary words and other common phrases to break the passwords.

Furthermore, to be unique, you can avoid using a password that’s related to your WordPress site and use a creative mixture of upper case and lower case letters, numbers, and symbols. This way, you will be making the work of someone trying to guess your password hard.

For instance, you can choose a random word or phrase and insert letters and numbers throughout it to increase complexity (such as “uTo7pyr$ll0%w4Ge”).

To make such complex passwords easier to remember but difficult for others to guess, you can take a sentence and convert it into a password by abbreviating words and creatively adding other memorable components.

For example, “I and my wife went for a holiday to Singapore for $3,500” could be “Iamww4@h2S4$35”. And, “Woohoo! I Blog Seven times a Week for money and fun” could translate to something like “WOO!IbG7#aWk4$+f”.

Here is how you can substitute some of the alphabets:

A= @

I= 1

L=!

o= 0 (zero)

S=$

Z= 2

Better still, you can use convenience software like LastPass and 1Password for remembering your strong, complex passwords.

As earlier mentioned here at Legit Blogger, avoid using commonly used words or sequential patterns that make the work of hackers easy.

The reason why “1qaz2wsx” made it to the list of the 25 worst passwords of 2015 (though it seems to be strong) is because it’s based on a sequential pattern of the initial two column keys on a standard computer keyboard.

So, better be safe than sorry and inject uniqueness and some creativity into your passwords.

  1. Do not fall prey of “phishing” attacks

If you receive an email from your hosting company or another source prompting you to change the login details of your cPanel, update the login details of your site, or provide other sensitive information, be careful before responding to such a message.

Before clicking on any links, ensure that the source is legitimate or you may fall a victim of a “phishing” attack.

If you provide your password details to a malicious website, a hacker could get hold of the information and make you curse, instead of blessing, your blogging life.

  1. Consider using WordPress security plugins

It prevents WordPress users with administrative access privileges from entering weak passwords. With this innovative plugin, a user can only publish posts, upload files, or edit posts only with a strong verified password.

These plugins will incorporate an additional layer of security to your WordPress blog by using a combination of two separate security credentials, for example, sending you a unique code to your mobile phone each time you want to log into your site, in addition to requiring you to enter your usual log in details.

As the name suggests, this innovative plugin will restrict the number of times a user can enter a password to gain access to a site. Therefore, someone trying to use a brute force attack to compromise your site has fewer chances.

With this powerful plugin, your WordPress site will be protected from malicious attacks by giving you frequent security updates, enforcing strong passwords, and accomplishing several other things.

  1. Length of password is key

The longer the password, the more secure it becomes in protecting your digital assets from malicious intrusions. It’s recommended to have passwords of at least 8 characters long. A good way to have longer passwords is to use passphrases.

Passphrases are just like passwords apart from being constructed from an unsystematic mixture of words, instead of just a single word. For example, press demonstrate blog million.

To create a passphrase, simply select a list of random numbers or use the free password creator tool. Thereafter, you can add some extra layer of robustness by a mixture of symbols, upper case letters, and lower case letters. Remember to avoid placing words in an easily predictable pattern and including easily identifiable phrases.

Furthermore, to have longer and stronger passwords, you can consider using a password manager. With such an application, you can safely create strong, lengthy passwords, which are kept in a secure database.

You can use a single passphrase to access the password manager; thereafter, the application will automatically enter your details on the login page of your WordPress site.

Because of the innovative capabilities of the password managers, it will not be necessary to remember your lengthy passwords every time you want to login into your site.

Click here for a list of the best passwords managers you can consider using.

  1. Keep your backup password options secure and up-to-date

Since WordPress.com uses your email address as the primary means of identification, you need to ensure that you frequently update your recovery email address.

Failure to keep the details of your email address up-to-date and secure could make an attacker to easily reset your passwords and login to your WordPress site.

Most free email service providers, such as Gmail and Yahoo mail, have a multi-factor authentication process.

When you enable this feature on your email account, you will be required to enter a short code sent to your mobile device and answer a series of security questions before accessing your account from an unrecognized device.

This way, the possibility of your account going into the wrong hands is greatly reduced.

  1. Be proactive
  • After creating a password, check its strength using this free tool. If it’s weak, you may continue modifying it until you get something solid.
  • Change your WordPress login details as frequently as possible. Using “Admin” as username and the name of your site as the password without frequently making improvements could land you into the land controlled by hackers.
  • Do not dish your passwords to anyone, even your “close” friends. You may never know how much they are concerned about the security of your site.
  • If you have to send your passwords through email, use a secure method of transmission such as com and select the password expiry time. If you send naked passwords through emails, which are rarely encrypted, the bad guys could get old of them.
  • When on a public computer, avoid saving your passwords or using the “Remember Me” feature, Further, watch out for people trying to look at your screen over your shoulder and remember to log out or close down your computer after you have finished your work.

Conclusion

Having your site compromised by an attacker is a horror that few webmasters are prepared to endure. Ensuring that your site is up and running normally after a successful attack requires thick skin, patience, and money.

Nonetheless, security issues are vital for the optimal performance of any WordPress website or blog. Therefore, instituting ample security measures beforehand is normally better than tackling the aftermath.

Fortunately, the robust WordPress platform, which is trusted by a large number of site owners, is generally very safe. And, one of the vital ways of keeping a WordPress site free from attackers is by vigilantly using strong and secure passwords.
