Numerous email scams land in your inbox every day, from malware-ridden attachments supposedly from a friend to IRS impersonators to blackmailers threatening to expose you for watching pirated videos. And what makes many of these scams harder to recognize is that they rely on a โspoofedโ email address to make it appear that they are coming from someone you trust (or even your own email address), rather than a scammer 7,000 miles away. So learning how to identify if an email has been spoofed is crucial to protecting yourself.
Part of the reason why spoofed emails are so prevalent is that it is incredibly easy to spoof an address. Any mail server can be set up to send from a given domain (e.g. irs.gov), and there are even websites that will let you send one-off emails using any email address for free. But both of these methods leave telltale tracks that give it away as spoofed.
To find these tracks, you need to look at the email header. The header contains critical components of every email โ From, To, Date and Subject โ as well as detailed information about where the email came from and how it was routed to you. Importantly, it also contains the results of the verification process your email provider used to determine if the sending server has permission to send using that domain (i.e., Is this server authorized to send emails from irs.gov?).
Showing your email headers varies depending on which email service youโre using. For Gmail, open the email and click on the three vertical dots next to the reply arrow and select โShow Originalโ. For other email programs, you can use this list.
On the ๐ฎ๐ป๐ฑ ๐ฝ๐ถ๐ฐ๐๐๐ฟ๐ฒ, is an example of a spoofed email I sent from an online spoofing service pretending that it came from my own address. Looks pretty real. It says it came from my email address and if I reply, it will go to that same address. In fact, unless it was filtered into my spam box by Gmail, the email will even show up in my Sent folder, which could leave me to believe, incorrectly, that my email was hacked.
But the header information gives it away as spoofed. Thereโs a lot of technical stuff in here, but you can ignore most of it. The two things that matter the most are the domain name and IP address in the โReceivedโ field and the validation results in the Received-SPF field.
As you can see on the ๐ฏ๐ฟ๐ฑ ๐ฝ๐ถ๐ฐ๐๐๐ฟ๐ฒ, the domain name this email being sent from is emkei.cz (the email spoofing site), not achievement.com, so thatโs a dead giveaway. But if the domain name is similar or itโs listed as just an IP address you should check the IP address, too, and see if that passes the smell test. To do that, go to Domain Tools and enter the โfromโ IP address in the Received field into the Whois Lookup. When I do that with 46.167.245.206 from the example above, it tells me this is a host called emkei.cz out of the Czech Republic โ not what I would expect to see if this were really an email sent by achievement.
Next, if we look at the Received-SPF field and see that it is a softfail. Sender Policy Framework (SPF) is a way for a domain (e.g., achievement.com) to specify what servers are permitted to send mail on its behalf. Mail sent from permitted servers will show up as โPassโ in the Received-SPF field, which is a very strong indicator that the email is legitimate. If the results show โFailโ or โSoftfailโ, thatโs a sign the email may be spoofed, though itโs not 100% certain since some domains donโt keep their SPF records up to date, resulting in validation failures.
Taken together, the sending IP address and the SPF validation will give you a very good sense of whether an email truly comes from the person purported to be sending it. And donโt forget to trust your gut. If an email sounds implausible, it probably is. Donโt respond directly or open any attachments. If it is a company, bank or government organization, find their contact information on the web and contact them directly to see if the email is legit.
Spoofing email is just one way scammers attempt to take advantage of us. So ensure that you have also a basic knowledge of other cybercrimes to prevent your business from falling into the hands of cybercriminals.

Moving to the cloud isnโt an all or nothing deal. Thereโs no need to rip out your existing servers, think of hybrid clouds. The decision is usually governed by your internal SLAs, security, and cost considerations. There are three main types of cloud to choose from - public, private, and hybrid. Each one comes with its own pros and cons.
โข ๐ฃ๐๐ฏ๐น๐ถ๐ฐ ๐๐น๐ผ๐๐ฑ
The public cloud is an off-premise multi-tenant solution. It is easy to use and access from internet-connected devices. Users do not have to jump many hurdles to access the services. Public clouds are highly flexible allowing you to easily add or drop capacity. This elasticity also contributes to its cost-effectiveness as they usually operate a pay-as-you-go model. Public clouds can suffer from outages, may be more susceptible to hacks, and are less secure.
โข ๐ฃ๐ฟ๐ถ๐๐ฎ๐๐ฒ ๐๐น๐ผ๐๐ฑ
Private cloud services arenโt shared and are developed specifically for your company. These can be maintained onsite or in a privately hosted data center. This gives you greater control over your cloud infrastructure and stored data. In addition, private clouds have stronger SLAs, hence increased reliability. While the cost of private clouds is higher, it is much more secure than public clouds.
โข ๐๐๐ฏ๐ฟ๐ถ๐ฑ ๐๐น๐ผ๐๐ฑ
Hybrid cloud means two or more clouds connected to support load balancing between private in-house resources and virtualized resources in the public cloud. It allows you to create an ideal configuration, balancing cost, and security. You get the advantage of the cost-effectiveness of the public cloud and enjoy the security of the private cloud.
