Mac address spoofer free download - IP Address Menu, Apple Address Book Importer, MacAppStuff Spoof MAC, and many more programs. But before moving on with our spoofing mac address OS X trick, let’s see what does a MAC address look like. MAC address is the lower sub-layer of the data link layer in the Open System Interconnection (OSI) model. It is a six-byte number. MAC address is also often referred as the Physical Address. A possible MAC address can be 2F-4D-5B-6E-2A-9C. Theoretically, every network device in the world is identified by a MAC address. But not every user wants this transparency on the internet. One reason to mask your MAC address is for the protection of privacy – for example, in public WLAN networks. This legitimate use of MAC spoofing is in opposition to the illegal activities, where users change MAC addresses to circumvent access. Maildrop is an excellent email spoofing tool that provides a great email generation service for all those (pretty much every one of us) who doesn’t like giving their work email address. It works exactly like the other mail generators that create an inbox of your desired name.
As email remains one of the primary communications channels for private individuals, commercial or non-commercial organizations, and government institutions, it’s little wonder that it also continues to be a medium of choice for hackers and cyber-criminals.
Two of their preferred attack methods are impersonation and fraud – both of which may be readily accomplished by spoofing the internet domains associated with legitimate email entities so that the perpetrators can send messages to their intended victims which seem to originate from the email accounts of trusted names.
This problem has escalated to the extent that the US Department of Homeland Security (DHS) has been forced to issue a directive mandating all US federal government agencies to authenticate their email so as to prevent spoofing. But it’s not only government that should be taking such precautions. And in this article, we’ll be looking at how secure email protocols such as DMARC and DKIM can help detect and prevent email spoofing.
Email Spoofing – The Scale of the Problem
![Email Email](/uploads/1/1/9/5/119590555/726170853.png)
Of the more than 100 billion business emails sent during 2013, only 20% were actually legitimate – and 92% of all the illegitimate emails housed links to potentially malicious software or content.
Flash forward to the present, and in a 2017 Proofpoint study of email metadata from around 70 million messages, over 8.5 million fraudulent messages were found. This statistic is particularly significant as the research covered 4,989 unique .gov (US government registered) parent domains, spanning federal, state, and local agencies. Almost 10% of the fraudulent emails discovered were sent from IP addresses outside the United States.
Besides the “usual suspects” – like Russia, which accounted for 27% of malicious emails spoofing institutional identities since January 2016 – the study observed spoofed .gov emails originating from 187 different foreign countries, in the month of October alone. In fact, 12.4% of all the emails sent from .gov domains in that month originated from foreign IP addresses.
In 98.5% of email fraud cases, cyber-criminals spoofed the domain of a US government entity, effectively hijacking 3,134 different domains across 296 federal agencies and departments, plus hundreds of state and local government organizations.
Because of statistics like these, the US Department of Homeland Security issued BOD 18-01 – a directive mandating federal agencies to authenticate their email as a measure towards eliminating the ability of fraudsters to impersonate US federal agencies.
And to achieve this end, organizations and individuals are advised to implement their best combination of the email security standards that we’ll now describe.
Sender Policy Framework (SPF)
The Sender Policy Framework or SPF was one of the earliest attempts to counter email spoofing activities. Still in existence today, SPF is an open standard which specifies a method for preventing sender address forgery. Email sender forgery is typically associated with spam (unsolicited bulk mail), fraud, malware distribution, and phishing attacks.
Under the SPF protocol, senders use an SPF record published in DNS (the Domain Name System) to specify which servers are allowed to send email for a particular domain. So you can use SPF to identify your internet domain’s legitimate email sources and prevent unauthorized sources from sending illicit or fraudulent emails from your domain.
SPF is all about controlling and preventing attempted sender forgeries, rather than proactively eliminating spam. However, the method only works on the domain in the SMTP (Simple Mail Transfer Protocol) sending protocol, which is known as the MAIL FROM envelope address. Consumer-level email software doesn’t display this address – and as a consequence, SPF is of most value as a lower-level warning sign for email service providers.
Preventing Email Spoofing with DKIM – DomainKeys Identified Mail
DomainKeys Identified Mail or DKIM is a text-based (TXT) record published in the Domain Name System, which allows a particular domain owner to cryptographically sign parts of a message so that a recipient can validate that they haven’t been altered in transit.
Under DKIM, public and private encryption key pairs are generated to ensure that mail servers and communications can be authenticated. Each Simple Mail Transfer Protocol server must have the correct private key and prefix in order to match a public DNS record which the receiving mail server then verifies.
Generally speaking, if an email recipient validates a communication sent under DKIM, the body content and specified headers (From:, To:, Subject:, etc.) have not been modified by anyone along the way.
Using the DKIM standard, an email recipient can associate a single domain or multiple domains (if multiple DKIM signatures have been placed on an email) with each signed message. So a log of “trusted” and “untrusted” emails may be built up over time and associated with given domains, IP addresses, From: identities, and other criteria.
The system can stutter under certain conditions. For example, if DKIM signing isn’t implemented across all departments of a particular organization, this may generate some confusion. Also, as DKIM signatures may be made using any domain name, it can be difficult to establish which domains of origin are actually trustworthy.
Preventing Email Spoofing with DMARC – Domain-based Message Authentication, Reporting, and Conformance
Domain-based Message Authentication, Reporting, and Conformance or DMARC takes a combined approach, by allowing a message sender to indicate whether their messages are protected with SPF and/or DKIM. By publishing a record in the Domain Name System (DNS), domain owners can specify what email recipients should do with any email received from their domain.
If you publish a DMARC record for your domain, email recipients should first check that the From: header domain matches the DKIM signing domain (this is known as alignment) and that the DKIM signature is valid. They may also verify that the From: header domain matches the SMTP MAIL FROM domain and that the sender’s IP address is validated by SPF. If either or both conditions are true, the email passes the DMARC test.
A DMARC policy will clearly stipulate what a message recipient should do if an email doesn’t pass SPF or DKIM authentication. For example, they may be instructed to reject the message or delete it. In addition, DMARC will send a report back to the sender about messages that PASS and/or FAIL the DMARC evaluation.
DMARC is considered as a strong anti-phishing protocol. Since measures are in place to ensure that the domain in the From: address of an email can’t be forged (for domains which DKIM sign their emails and publish a DMARC policy), identity spoofing becomes that much harder for the enterprising fraudster.
There is, of course, a caveat, here. Since DMARC allows you to use either SPF or DKIM to verify a message, some users rely solely on SPF, and don’t DKIM sign their messages. If a message created in this way is forwarded from one email provider to another, the DMARC test will fail. So organizations and individuals are advised to always DKIM sign their mail if they have a DMARC policy in place.
Deploying These Standards to Prevent Email Spoofing
Depending on the software and email platforms being used, there are a number of methods for implementing SPF, DKIM, and DMARC to prevent email spoofing. Google publishes a guide for configuring SPF records to work with Google Apps – which is a good place to start for those new to the standard.
Likewise, the articles Authenticate email with DKIM (published by Google) and Enhancing Email Security: Stop Sender Fraud with SPF, DKIM, and DMARC (on BetterCloud.com) give step-by-step examples on setting up DKIM and DMARC spoof protection.

MAC address short form of Media Access Control Address, is a address that uniquely identifies you computer. For every network card on your computer there is a MAC address, which comes built-in. This applies to all types of network cards be it Ethernet or WiFi. Whether you are using a wired connection or wireless one, you do need to transfer data from your computer to some other computer. But how does the other computer find your computer? That is where addresses come in. These addresses are actually hard-coded into the network card. These are given to a network adapter in the manufacturing stage itself. And since these addresses are permanent, they are generally used to prevent devices from accessing a particular network. Does this mean they can never be changed? Well, yes. Then what is this article about? One simple word, MAGIC ! The hard-coded MAC address can never be changed but you can spoof the MAC address in your operating system. But before moving on with our spoofing mac address OS X trick, let’s see what does a MAC address look like.
MAC address is the lower sub-layer of the data link layer in the Open System Interconnection (OSI) model. It is a six-byte number. MAC address is also often referred as the Physical Address. A possible MAC address can be 2F-4D-5B-6E-2A-9C. As you can clearly see it is a 12-digit hexadecimal or 48 bits number. The first 6 digits helps to find the manufacturer, while the last six digits find your device. The manufacturers have already got this special number sequence to find themselves as manufactures. Dell has 00-14-22 at the beginning, Cisco has 00-40-96 and so on. These are often referred as OUI or Organizationally Unique Identifier. The last 6 digits or three bytes is the NIC (Network Interface Controller) specifier. A possible question now arises that why would someone like to change their MAC address? It is for so many reasons. If your network limits access to some MAC addresses, then you can change it and have the network access. If a network filters out access based on MAC address, then you can sniff out a legitimate MAC address, change your MAC address and connect. If you want privacy over surfing or any network activity, you could change your MAC address and be untraceable. You can also bypass certain network restriction by spoofing an authorized MAC address. There are many more reasons one might want to change his/her computers MAC address. Let’s not go to too much detail and begin.
Before changing the MAC address on Mac Computer let’s see how can you look up your MAC address. There are generally three ways to go about it.

1. Easy
Press and hold the option key, now click on the WiFi icon from the menu bar. You will see couple of things here, look out for “Address:”. The next 12 hexadecimal digits following it is your MAC address. And it tells you the connection name also. Wasn’t it easy?
2. Medium
WiFi Spoof MAC
Open up System Preference and now move on to Network section. Select the network via which you are connected and then click on the Advanced button. Now, select the Hardware tab, the first thing you will see is MAC address.
3. Advanced
This is the toughest one of the all. Open up the terminal and type the command:
ifconfig en0 | grep ether
This actually shows the MAC address for en0 interface. Just change the name of the interface and look for yourself. Was it that difficult?
Now, that we know our MAC address, let us generate some random MAC addresses, in the terminal just type:
openssl rand -hex 6 | sed ‘s/(..)/1:/g; s/.$//’
This will generate a random MAC address. The format of MAC address as earlier mentioned in this article is in the form xx:xx:xx:xx:xx:xx, if you already have one in mind you don’t need to generate one. But keep in mind it should be 12 digits hexadecimal.
changing mac address on macOS sierra or OS X Yosemite or OS X El Capitan or any Mac OS X is just one command, open up the terminal and type in:
sudo ifconfig en0 ether xx:xx:xx:xx:xx:xx
You need to have administrative privileges to change the MAC address, hence it will ask for the password. It is best recommended that you disconnect from the network while changing your MAC address and then again reconnect after successfully changing it. Also, make a note of your default hardware MAC address. Some the MAC use Wi-Fi instead of ether in the above command. if you meet any problem try to use Wi-Fi. Remove the xx:xx:xx:xx:xx:xx with your MAC address generated or you have in mind. And also replace en0 with any other interface name that you are using. If you don’t know the interface name, you should check it from the above mentioned steps. To confirm that it has been changed you could use any of the above mentioned way. If you are changing your MAC address to get privacy you better generate random MAC address.

After changing the MAC address on your OS X or sierra or yosemite or el capitan it might be possible that you meet network issues, in that case make sure you turn off and then turn on your network device. You can use the method and get around with any blocking. It sounded a very difficult task at the beginning, but even you can see how easy it was. Let me know, how did it go for you?
