Tips For Recognizing a Phishing Email

Below are some common tips for helping to identify phishing emails at work or at home. The same rules apply.

Most Phishing Emails Originate at Common Domains

The first way to recognize a phishing email is that most originate from a public email domain.

There are few legitimate organizations that will send emails from an address that ends in @gmail.com, not even Google does this.

To check an organization’s name, type it into a search engine.Most of the time, organizations have their own email and company accounts and don’t need to use an @gmail.com address.

Check the Spelling of the Domain, Carefully!

There is another clue hidden in domain names that shows a strong indication of the scam.

Anyone can purchase a domain name from a website. There are many ways to create addresses that are easily confused with the official domain of a brand or company. The most common ways include slight mis-spellings of the domain name, or by changing one character to a number or letter that resembles the original. Be extra vigilant for these types of spoofing attempts.

Grammer and Spelling Counts

It’s often possible to tell if an email is a scam if it has poor spelling and grammar. Odd terminology or phrasing is also a clue. For example, your bank is unlikely to misspell the word checking or account, and they would not usually call an ATM machine a “cash machine”. These clues can be subtle, but often indicate that an email is not what it claims to be.

Beware of Potentially Malicious Links and Attachments

Sometimes, the wording in an email might be right, but the links send you to somewhere unexpected on the web. You can check this out in most clients and browsers by simply hovering the mouse cursor over the link without clicking on it. That’s an easy way to know where the link is taking you, and note that it might be somewhere other than what the links says it is.

You should always beware of attachments in emails. Everyone knows that malicious code and ransomware can be hiding in documents, spreadsheets and such, but they can also appear to be image files, presentations, PDFs and most types of documents. If you aren’t expecting the attachment, delete it!

Too Good To Be True

Lastly, if the offer is too good to be true, it probably is. Few people have won the lottery and been notified by email. Even less have been chosen for random gifts or to receive inheritance from Kings and Queens. Don’t be gullible, and remember, scammers are out there, and they want to trick you.

What to Do When You Spot a Phish

The first thing is to delete the email and attachments. If it is a work email, you should also notify the security team that you received it. They can investigate, as needed. In some firms, they may want you to forward it to a specific email address for the security team, but most security teams can recover the email information even if you delete it. Follow their instructions.

At home, just delete the email and tell your family and friends about it. The more folks are aware of what’s going around, the less likely there are to fall into the trap.

Phishing URLs

How many of us inspect a link before we actually click on it? Be honest now, how many hover your mouse over the link and identify the destination in the status bar or popup, before you actually click? If the link is from a trusted site, say in the middle of a CNN article, very likely you don’t. If it’s a link in an email from your colleague, maybe. And even then, how closely do you look?

In many of MicroSolved’s social engineering exercises, alright, authorized phishing campaigns, creating fake links that appear valid is a tried and true method. To make an email look like it’s from John Glenn, a very familiar name recognized as an American hero, it takes 2 minutes to create an email address JohnGlemn@gmail.com. Or BilllyCrystal@gmail.com. Alright, how many of you actually caught the 3 lower case L’s in Billly? And the misspelling of Glemn in the email address?

Same thing with domains. Not to pick on this domain but why is MICRPSOFT.COM registered? Don’t browse to that domain, it gets forwarded to a suspicious link – which proves the point. An internet search for the string “MICRPSOFT” comes up with nothing for that string, all results are for “MICROSOFT.”

It’s a common technique referred to as URL hijacking or Typosquatting. It counts on the user not paying attention to what they’re typing into the browser address bar. Or it counts on the user not noticing the misspelling even if they were hovering the mouse over a link before they clicked.

Many of you have heard of the Equifax breach earlier this year. They registered and set up a domain for the public – equifaxsecurity2017.com. At this site, you could get more information, as well as enter your SSN (last few digits) to find out if your personal data had been part of the breach. However, a security professional registered securityequifax2017.com – and many legitimate sites actually directed traffic to this fake domain instead. Fortunately, it wasn’t anyone malicious, but someone who wanted to prove the point – and did – that these domain names can easily be abused. Equifax itself tweeted the fake domain, thinking it was their own.

So what are we to do? It’s easy to say, just be vigilant, be cautious, be on the lookout. There are tools, browser plugins, background running processes that can check links or clicks. But here’s an anecdote on relying on an “automated” tool that does things for us. I was pulled over at dusk couple weeks ago (wasn’t night yet, could still see the setting sun), driving my wife’s car that did NOT have daytime running lights. My car does. I have so heavily relied on this automated feature that when I was in a different environment that did not have it, I forgot to check the basics – it’s getting dark, are my lights on? Incidentally, the officer just gave me a warning.

Recommendation is, be vigilant, be cautious, be on the lookout. Check those links or email addresses. Check the spelling. Type in the link instead of clicking on it. Copy the link and paste it into the browser address bar, and verify before pressing Enter to navigate to it.

It’s a jungle out there. Be safe…

NanoCore RAT

It’s been discovered that a Remote Access Trojan (RAT) named NanoCore has been cracked again. These cracked copies are being heavily distributed via the deep and dark web. Due to the fact that malicious actors are now able to obtain this RAT for free, there has been a spike of observed NanoCore infections. For example, it was recently reported that the cracked copies are being leveraged in phishing attacks against energy companies. Unfortunately, we anticipate that the attempted use of this RAT will increase over the next few weeks.
However, there is some good news regarding the spread of NanoCore. First, the observed methods for deploying this malware do not seem to be very complicated. The attacks appear to be leveraging basic e-mail phishing which can be prevented by tuning spam filters and performing security awareness training with staff. Second, the attacks appear to be attempting to exploit vulnerabilities that are 2-3 years old. Your organization’s workstations should already have patches installed that will prevent the malware from being deployed. Finally, several commercial IDS/IPS systems are already able to detect this RAT. To ensure that your organization is protected, be sure to verify that your IDS/IPS/AV signatures are up to date.
We are more than happy to answer any questions that you might have about this RAT. Feel free to contact us by emailing <info> at microsolved.com

How to Avoid Getting Phished

It’s much easier for an attacker to “hack a human” than “hack a machine”.  This is why complicated attacks against organizations often begin with the end user.  Although e-mails with malicious links or attachments are often dismissed and referred to as “spam”, these messages are often the beginning of a sophisticated hack against a company.  Unfortunately there is no “silver bullet” that can prevent these attacks from taking place.
 
I recently had the opportunity to give a presentation during one of our client’s all-staff meeting.  Despite the fact that our client’s company resides in a relatively niche market, I was able to discuss several data breaches that took place in their industry within the last year.  Not only did the hacks all take place recently, they were all the direct result of actions taken by an end-user.  A majority of these attacks were caused by an employee opening a malicious e-mail.  I gave our customer the following advice to help them avoid becoming a victim of Phishing e-mails and felt that it was worth sharing on StateOfSecurity.com.
 
Verify link URL:  If the e-mail you received contains a link, does the website URL match up with the content of the message?  For example, if the e-mail indicates you are about to visit a website for FedEx, is the address actually FedEx.com?  A common tactic used by attackers is to direct a user to a similar URL or IP address.  An example of this would be to direct the user to FedEx111.com or FedEx.SE as opposed to the organization’s actual URL.
 
Verify e-mail address of sender: If the e-mail message you received came from a friend, colleague or vendor, did it actually come from their e-mail address?  It’s worthwhile to take a few extra seconds to ensure that the e-mail actually came from the aforementioned colleague, friend or vendor.  Also, avoid opening e-mails from generic senders such as “Systems Administrator” or “IT Department”.
 
Exercise caution from messages sent by unknown senders: Be cautious if a message comes from an unknown sender.  Would you provide your checking account number or password to a random person that you saw on the street?  If not, then don’t provide confidential information to unknown senders.
 
Follow up with a phone call: In the event you receive a message requesting that you validate information or need to reset your password, take some time to follow up with the sender with a phone call.  Trust me, your IT department will be happy to spend a few seconds confirming or denying your request as opposed to dealing with a malware infection.  Also, if your “bank” sends any type of e-mail correspondence requesting that you perform some sort of action, it’s worthwhile to give them a call to confirm their intentions.  Always be sure to use a number that you found from another source outside of the e-mail.
Spot check for spelling/grammar errors: It is extremely common that malicious e-mails contain some sort of spelling mistake or grammatical error.  Spelling mistakes or grammatical errors are great indicators that you have received a malicious e-mail.
 
Do not open random attachments: If your e-mail messages meets any of the above criteria, DO NOT open the attachment to investigate further.  Typically these attachments or links are the actual mechanism for delivering malware to your machine.
