Gift card for answering if I shop online or in store. Email says it is from "thank you" and refers to Costco. Not sure if legit, so trashed.

My daughter (not a Costco member) DID open the Costco email thinking I had ordered something for her.

Boy was she surprised when her Windows laptop started playing short snippets of music and flashing messages to her screen about viruses infecting her computer.

One of the screens encouraged her to download a software program to remove the viruses for $49 - 6 month protection or $99 for lifetime protection.

She did not fall for this trap but instead called her father.

I rebooted her laptop and downloaded a free copy of malwarebytes from www.malwarebytes.org. (There are 8-10 other FREE antivirus software programs available to use - but I have used malwarebytes before and found it to be effective).

The download process was a bit difficult. The screen that shows the percent downloaded seem to terminate shortly after the download process started.

I proceeded to make 4 additional attempts to download the program - each seemed to end abruptly.

I then rebooted the laptop in SAFE MODE. Opened the download subdirectory and found 5 copies of the malwarebytes program did actually download.

After opening, installing and running malwarebytes it was able to identify 8 different Trojan files:

Trojan.Zemot File

Trojan.Agent.FSAVXGen File

Trojan.FakeAV Registry Value

Trojan.FakeAV File

Trojan.Agent.IGen Registry Value

Trojan.Agent.IGen File

Trojan.Agent.IGen Registry Key

Trojan.Agent.IGen Registry Key

Malwarebytes was able to quarantine all of the Trojan viruses and remove them from her laptop.

Me too, It drives me crazy this morning. I did not enter or download anything from the link. I am not even sure if the link opened. I think it said cannot open or cannot something. I turn those link off after a few seconds. I hope everything is ok. Not sure what antivirus software should I use for Macbook.

It is currently targeting the Windows operating system, but it is still not wise to click on the link if they you are using another operating system.

But, to be on the safe side, do a full scan of your computer with the antivirus software on your computer.

(12/1 Portland, OR) We just found one of these e-mails, (with wording identical to the one above)in our spam folder. It looked very suspicious so I called Costco online pharmacy's customer service and they agreed it was likely a scam and asked me to forward the e-mail to them, which I did.

Have not heard anything back from Costco so far. Fortunately we did not click on the embedded link, and our AV software (Norton)indicated it had found and removed malicious software which it identified as: vip_117[1].swf (Trojan Swifi)and flagged as very bad.

What's interesting is that I had recently submitted a prescription refill request to Costco, so am wondering if someone has hacked into their system - or perhaps it's just a coincidence.

Anyway we're glad our e-mail and AV programs did their job.

Just saw this email in my Spam folder and thought it was suspicious. My question is, how do they know that I indeed ordered from Costco.com in the last few days? Seems scary!

They do not know. They just send out the email message to everyone (even persons who did not shop at Costco), hoping they will trick someone who recently shopped at Costco.

We received the email although we have never shopped at Costco.

Online Threat Alerts Security Tips

Pay the safest way

Credit cards are the safest way to pay for online purchases because you can dispute the charges if you never get the goods or services or if the offer was misrepresented. Federal law limits your liability to $50 if someone makes unauthorized charges to your account, and most credit card issuers will remove them completely if you report the problem promptly.

Guard your personal information

In any transaction you conduct, make sure to check with your state or local consumer protection agency and the Better Business Bureau (BBB) to see if the seller, charity, company, or organization is credible. Be especially wary if the entity is unfamiliar to you. Always call the number found on a website’s contact information to make sure the number legitimately belongs to the entity you are dealing with.

Be careful of the information you share

Never give out your codes, passwords or personal information, unless you are sure of who you're dealing with

Know who you’re dealing with

Crooks pretending to be from companies you do business with may call or send an email, claiming they need to verify your personal information. Don’t provide your credit card or bank account number unless you are actually paying for something and know who you are sending payment to. Your social security number should not be necessary unless you are applying for credit. Be especially suspicious if someone claiming to be from a company with whom you have an account asks for information that the business already has.

Check your accounts

Regularly check your account transactions and report any suspicious or unauthorised transactions.

Don’t believe promises of easy money

If someone claims that you can earn money with little or no work, get a loan or credit card even if you have bad credit, or make money on an investment with little or no risk, it’s probably a scam. Oftentimes, offers that seem too good to be true, actually are too good to be true.

Do not open email from people you don’t know

If you are unsure whether an email you received is legitimate, try contacting the sender directly via other means. Do not click on any links in an email unless you are sure it is safe.

Think before you click

If an email or text message looks suspicious, don’t open any attachments or click on the links.

Verify urgent requests or unsolicited emails, messages or phone calls before you respond

If you receive a message or a phone call asking for immediate action and don't know the sender, it could be a phishing message.

Be careful with links and new website addresses

Malicious website addresses may appear almost identical to legitimate sites. Scammers often use a slight variation in spelling or logo to lure you. Malicious links can also come from friends whose email has unknowingly been compromised, so be careful.

Secure your personal information

Before providing any personal information, such as your date of birth, Social Security number, account numbers, and passwords, be sure the website is secure.

Stay informed on the latest cyber threats

Keep yourself up to date on current scams by visiting this website daily.

Use Strong Passwords

Strong passwords are critical to online security.

Keep your software up to date and maintain preventative software programs

Keep all of your software applications up to date on your computers and mobile devices. Install software that provides antivirus, firewall, and email filter services.

Update the operating systems on your electronic devices

Make sure your operating systems (OSs) and applications are up to date on all of your electronic devices. Older and unpatched versions of OSs and software are the target of many hacks. Read the CISA security tip on Understanding Patches and Software Updates for more information.

What if You Got Scammed?

Stop Contact With The Scammer

Hang up the phone. Do not reply to emails, messages, or letters that the scammer sends. Do not make any more payments to the scammer. Beware of additional scammers who may contact you claiming they can help you get your lost money back.

Secure Your Finances

  • Report potentially compromised bank account, credit or debit card information to your financial institution(s) immediately. They may be able to cancel or reverse fraudulent transactions.
  • Notify the three major credit bureaus. They can add a fraud alert to warn potential credit grantors that you may be a victim of identity theft. You may also want to consider placing a free security freeze on your credit report. Doing so prevents lenders and others from accessing your credit report entirely, which will prevent them from extending credit:

Check Your Computer

If your computer was accessed or otherwise affected by a scam, check to make sure that your anti-virus is up-to-date and running and that your system is free of malware and keylogging software. You may also need to seek the help of a computer repair company. Consider utilizing the Better Business Bureau’s website to find a reputable company.

Change Your Account Passwords

Update your bank, credit card, social media, and email account passwords to try to limit further unauthorized access. Make sure to choose strong passwords when changing account passwords.

Report The Scam

Reporting helps protect others. While agencies can’t always track down perpetrators of crimes against scammers, they can utilize the information gathered to record patterns of abuse which may lead to action being taken against a company or industry.

Report your issue to the following agencies based on the nature of the scam:

  • Local Law Enforcement: Consumers are encouraged to report scams to their local police department or sheriff’s office, especially if you lost money or property or had your identity compromised.
  • Federal Trade Commission: Contact the Federal Trade Commission (FTC) at 1-877-FTC-HELP (1-877-382-4357) or use the Online Complaint Assistant to report various types of fraud, including counterfeit checks, lottery or sweepstakes scams, and more.
  • Identitytheft.gov: If someone is using your personal information, like your Social Security, credit card, or bank account number, to open new accounts, make purchases, or get a tax refund, report it at www.identitytheft.gov. This federal government site will also help you create your Identity Theft Report and a personal recovery plan based on your situation. Questions can be directed to 877-ID THEFT.

How To Recognize a Phishing Scam

Scammers use email or text messages to try to steal your passwords, account numbers, or Social Security numbers. If they get that information, they could get access to your email, bank, or other accounts. Or they could sell your information to other scammers. Scammers launch thousands of phishing attacks like these every day — and they’re often successful.

Scammers often update their tactics to keep up with the latest news or trends, but here are some common tactics used in phishing emails or text messages:

Phishing emails and text messages often tell a story to trick you into clicking on a link or opening an attachment. You might get an unexpected email or text message that looks like it’s from a company you know or trust, like a bank or a credit card or utility company. Or maybe it’s from an online payment website or app. The message could be from a scammer, who might

  • say they’ve noticed some suspicious activity or log-in attempts — they haven’t
  • claim there’s a problem with your account or your payment information — there isn’t
  • say you need to confirm some personal or financial information — you don’t
  • include an invoice you don’t recognize — it’s fake
  • want you to click on a link to make a payment — but the link has malware
  • say you’re eligible to register for a government refund — it’s a scam
  • offer a coupon for free stuff — it’s not real
