How to Recognize a Phishing Email

How do you recognize phishing emails and texts? Even as many of the scammers behind them have sophisticated their attacks, you can still pick out telltale signs.

Common to them all, every phishing is a cybercrime that aims to steal your sensitive info. Personal info. Financial info. Other attacks go right for your wallet by selling bogus goods or pushing phony charities.

You’ll find scammers posing as major corporations, friends, business associates, and more. They might try to trick you into providing info like website logins, credit and debit card numbers, and even precious personal info like your Social Security Number.

How do you spot a phishing message?

Phishing scammers often undo their own plans by making simple mistakes that are easy to spot once you know how to recognize them. Check for the following signs of phishing when you open an email or check a text:

It’s poorly written.

Even the biggest companies sometimes make minor errors in their communications. Phishing messages often contain grammatical errors, spelling mistakes, and other blatant errors that major corporations wouldn’t make. If you see glaring grammatical errors in an email or text that asks for your personal info, you might be the target of a phishing scam.

The logo doesn’t look right.

Phishing scammers often steal the logos of the businesses they impersonate. However, they don’t always use them correctly. The logo in a phishing email or text might have the wrong aspect ratio or low resolution. If you have to squint to make out the logo in a message, the chances are that it’s phishing.

The URL doesn’t match.

Phishing always centers around links that you’re supposed to click or tap. Here are a few ways to check whether a link someone sent you is legitimate:

  • On computers and laptops, you can hover your cursor over links without clicking on them to see the web address. On mobile devices, you can carefully check the address by holding down the link (not tapping it).
  • Take a close look at the addresses the message is using. If it’s an email, look at the email address. Often, phishing URLs contain misspellings. Maybe the address doesn’t match the company or organization at all. Or maybe it looks like it almost does, yet it adds a few letters or words to the name. This marks yet another sign that you might have a phishing attack on your hands.
  • Scammers also use the common tactic of a link shortener, which creates links that almost look like strings of indecipherable text. These shortened links mask the true address, which might indeed be a link to a scam site. Delete the message. If possible, report it. Many social media platforms and messaging apps have built-in controls for reporting suspicious accounts and messages.

What kind of phishing scams are there?

You can also spot a phishing attack when you know what some of the most popular scams are:

The CEO Scam

This scam appears as an email from a leader in your organization, asking for highly sensitive info like company accounts, employee salaries, and Social Security numbers. The hackers “spoof”, or fake, the boss’ email address so it looks like a legitimate internal company email. That’s what makes this scam so convincing — the lure is that you want to do your job and please your boss. But keep this scam in mind if you receive an email asking for confidential or highly sensitive info. Ask the apparent sender directly whether the request is real before acting.

The Urgent Email Attachment

Phishing emails that try to trick you into downloading a dangerous attachment that can infect your computer and steal your private info have been around for a long time. This is because they work. You’ve probably received emails asking you to download attachments confirming a package delivery, trip itinerary, or prize. They might urge you to “respond immediately!” The lure here is offering you something you want and invoking a sense of urgency to get you to click.

The “Lucky” Text or Email

How fortunate! You’ve won a free gift, an exclusive service, or a great deal on a trip to Las Vegas. Just remember, whatever “limited time offer” you’re being sold, it’s probably a phishing scam designed to get you to give up your credit card number or identity info. The lure here is something free or exciting at what appears to be little or no cost to you.

The Romance Scam

This one can happen completely online, over the phone, or in person after contact is established. But the romance scam always starts with someone supposedly looking for love. The scammer often puts a phony ad online or poses as a friend-of-a-friend on social media and contacts you directly. But what starts as the promise of love or partnership, often leads to requests for money or pricey gifts. The scammer will sometimes spin a hardship story, saying they need to borrow money to come visit you or pay their phone bill so they can stay in touch. The lure here is simple — love and acceptance.

Account Suspended Scam

Some phishing emails appear to notify you that your bank temporarily suspended your account due to unusual activity. If you receive an account suspension email from a bank that you haven’t opened an account with, delete it immediately, and don’t look back. Suspended account phishing emails from banks you do business with, however, are harder to spot. Use the methods we listed above to check the email’s integrity, and if all else fails, contact your bank directly instead of opening any links within the email you received.

How to avoid phishing attacks

While you can’t outright stop phishing attacks from making their way to your computer or phone, you can do several things to keep yourself from falling for them. Further, you can do other things that might make it more difficult for scammers to reach you.

  • Pause and think about the message for a minute.

The content and the tone of the message can tell you quite a lot. Threatening messages or ones that play on fear are often phishing attacks, such as angry messages from a so-called tax agent looking to collect back taxes. Other messages will lean heavily on urgency, like a phony overdue payment notice. And during the holidays, watch out for loud, overexcited messages about deep discounts on hard-to-find items. Instead of linking you off to a proper e-commerce site, they might link you to a scam shopping site that does nothing but steal your money and the account info you used to pay them. In all, phishing attacks indeed smell fishy. Slow down and review that message with a critical eye. It might tip you off to a scam.

  • Deal directly with the company or organization in question.

Some phishing attacks can look rather convincing. So much so that you’ll want to follow up on them, like if your bank reports irregular activity on your account or a bill appears to be past due. In these cases, don’t click on the link in the message. Go straight to the website of the business or organization in question and access your account from there. Likewise, if you have questions, you can always reach out to their customer service number or web page.

  • Consider the source.

Some phishing attacks occur in social media messengers. When you get direct messages, consider the source. Consider, would an income tax collector contact you over social media? The answer there is no. For example, in the U.S. the Internal Revenue Service (IRS) makes it clear that they will never contact taxpayers via social media. (Let alone send angry, threatening messages.) In all, legitimate businesses and organizations don’t use social media as a channel for official communications. They’ve accepted ways they will, and will not, contact you. If you have any doubts about a communication you received, contact the business or organization in question directly. Follow up with one of their customer service representatives.

  • Don’t download attachments. And most certainly don’t open them.

Some phishing attacks involve attachments packed with malware, like ransomware, viruses, and keyloggers. If you receive a message with such an attachment, delete it. Even if you receive an email with an attachment from someone you know, follow up with that person. Particularly if you weren’t expecting an attachment from them. Scammers often hijack or spoof email accounts of everyday people to spread malware.

  • Remove your personal info from sketchy data broker sites.

How’d that scammer get your phone number or email address anyway? Chances are, they pulled that info off a data broker site. Data brokers buy, collect, and sell detailed personal info, which they compile from several public and private sources, such as local, state, and federal records, plus third parties like supermarket shopper’s cards and mobile apps that share and sell user data. Moreover, they’ll sell it to anyone who pays for it, including people who’ll use that info for scams. You can help reduce those scam texts and calls by removing your info from those sites. Our Personal Data Cleanup scans some of the riskiest data broker sites and shows you which ones are selling your personal info.

  • Use online protection software.

Online protection software can protect you in several ways. First, it can offer web protection features that can identify malicious links and downloads, which can help prevent clicking them. Further, features like our web protection can steer you away from dangerous websites and block malware and phishing sites if you accidentally click on a malicious link. Additionally, our Scam Protection feature warns you of sketchy links in emails, texts, and messages. And overall, strong virus and malware protection can further block any attacks on your devices. Be sure to protect your smartphones in addition to your computers and laptops as well, particularly given all the sensitive things we do on them, like banking, shopping, and booking rides and travel.

The State of Ransomware

Palo Alto Networks published its semi-annual report on ransomware. From the Executive Summary:

Unit 42 monitors ransomware and extortion leak sites closely to keep tabs on threat activity. We reviewed compromise announcements from 53 dedicated leak sites in the first half of 2024 and found 1,762 new posts. This averages to approximately 294 posts a month and almost 68 posts a week. Of the 53 ransomware groups whose leak sites we monitored, six of the groups accounted for more than half of the compromises observed.

In February, we reported a 49% increase year-over-year in alleged victims posted on ransomware leak sites. So far, in 2024, comparing the first half of 2023 to the first half of 2024, we see an even further increase of 4.3%. The higher level of activity observed in 2023 was no fluke.

Activity from groups like Ambitious Scorpius (distributors of BlackCat) and Flighty Scorpius (distributors of LockBit) has largely fallen off due to law enforcement operations. However, other threat groups we track such as Spoiled Scorpius (distributors of RansomHub) and Slippery Scorpius (distributors of DragonForce) have joined the fray to fill the void.

National Public Data Published Its Own Passwords

New details are emerging about a breach at National Public Data (NPD), a consumer data broker that recently spilled hundreds of millions of Americans’ Social Security Numbers, addresses, and phone numbers online. KrebsOnSecurity has learned that another NPD data broker which shares access to the same consumer records inadvertently published the passwords to its back-end database in a file that was freely available from its homepage until today.

In April, a cybercriminal named USDoD began selling data stolen from NPD. In July, someone leaked what was taken, including the names, addresses, phone numbers and in some cases email addresses for more than 272 million people (including many who are now deceased).

NPD acknowledged the intrusion on Aug. 12, saying it dates back to a security incident in December 2023. In an interview last week, USDoD blamed the July data leak on another malicious hacker who also had access to the company’s database, which they claimed has been floating around the underground since December 2023.

Following last week’s story on the breadth of the NPD breach, a reader alerted KrebsOnSecurity that a sister NPD property — the background search service recordscheck.net — was hosting an archive that included the usernames and password for the site’s administrator.

A review of that archive, which was available from the Records Check website until just before publication this morning (August 19), shows it includes the source code and plain text usernames and passwords for different components of recordscheck.net, which is visually similar to nationalpublicdata.com and features identical login pages.

The exposed archive, which was named “members.zip,” indicates RecordsCheck users were all initially assigned the same six-character password and instructed to change it, but many did not.

According to the breach tracking service Constella Intelligence, the passwords included in the source code archive are identical to credentials exposed in previous data breaches that involved email accounts belonging to NPD’s founder, an actor and retired sheriff’s deputy from Florida named Salvatore “Sal” Verini.

Reached via email, Mr. Verini said the exposed archive (a .zip file) containing recordscheck.net credentials has been removed from the company’s website, and that the site is slated to cease operations “in the next week or so.”

“Regarding the zip, it has been removed but was an old version of the site with non-working code and passwords,” Verini told KrebsOnSecurity. “Regarding your question, it is an active investigation, in which we cannot comment on at this point. But once we can, we will [be] with you, as we follow your blog. Very informative.”

The leaked recordscheck.net source code indicates the website was created by a web development firm based in Lahore, Pakistan called creationnext.com, which did not return messages seeking comment. CreationNext.com’s homepage features a positive testimonial from Sal Verini.

There are now several websites that have been stood up to help people learn if their SSN and other data was exposed in this breach. One is npdbreach.com, a lookup page erected by Atlas Data Privacy Corp. Another lookup service is available at npd.pentester.com. Both sites show NPD had old and largely inaccurate data on Yours Truly.

The best advice for those concerned about this breach is to freeze one’s credit file at each of the major consumer reporting bureaus. Having a freeze on your files makes it much harder for identity thieves to create new accounts in your name, and it limits who can view your credit information.

A freeze is a good idea because all of the information that ID thieves need to assume your identity is now broadly available from multiple sources, thanks to the multiplicity of data breaches we’ve seen involving SSN data and other key static data points about people.

Screenshots of a Telegram-based ID theft service that was selling background reports using hacked law enforcement accounts at USInfoSearch.

There are numerous cybercriminal services that offer detailed background checks on consumers, including full SSNs. These services are powered by compromised accounts at data brokers that cater to private investigators and law enforcement officials, and some are now fully automated via Telegram instant message bots.

In November 2023, KrebsOnSecurity wrote about one such service, which was being powered by hacked accounts at the U.S. consumer data broker USInfoSearch.com. This is notable because the leaked source code indicates Records Check pulled background reports on people by querying NPD’s database and records at USInfoSearch. KrebsOnSecurity sought comment from USInfoSearch and will update this story if they respond.

The point is, if you’re an American who hasn’t frozen their credit files and you haven’t yet experienced some form of new account fraud, the ID thieves probably just haven’t gotten around to you yet.

All Americans are also entitled to obtain a free copy of their credit report weekly from each of the three major credit bureaus. It used to be that consumers were allowed one free report from each of the bureaus annually, but in October 2023 the Federal Trade Commission announced the bureaus had permanently extended a program that lets you check your credit report once a week for free.

If you haven’t done this in a while, now would be an excellent time to order your files. To place a freeze, you’ll need to create an account at each of the three major reporting bureaus, EquifaxExperian and TransUnion. Once you’ve established an account, you should be able to then view and freeze your credit file. If you spot errors, such as random addresses and phone numbers you don’t recognize, do not ignore them. Dispute any inaccuracies you may find.
