OnMicrosoft.com Office 365 Malicious and Spam Emails

Spammers, scammers, or cyber-criminals are abusing Microsoft Office 365 by sending spam and malicious email messages from it, which they will use to trick their potential victims into sending them their money, personal and financial information, or clicking on links that will take them to malicious websites that will infect their computers with viruses, Trojan horse or other malware. Microsoft Office 365, often referred to as Microsoft 365 or Office 365, is a web-based version of Microsoft Office Suite.

How are Scammers Using Microsoft Office 365?

Spammers, scammers and cybercriminals are signing up for Office 365 accounts, creating email addresses and websites, and are using them to send spam and malicious email messages to their potential victims.

Here is an example:

The following fraudulent email message was sent to a potential victim; luckily she sent it to us to determine if it is legitimate:

Subject: Attn:This Is My Second Email, Please Respond
From: Ahmed Mohamed Ahmed01@lawoffice2013 .onmicrosoft.com

The cyber-criminals responsible for the fraudulent email created a website name or subdomain under “onmicrosoft.com” called “lawoffice2013”. The website or subdomain name looks like the following:”lawoffice2013.onmicrosoft.com

Then they created the email address “Ahmed01@ lawoffice2013.onmicrosoft.com” from the website or subdomain name. Once the email address has been created, they then send the spam and malicious email message above from it.

Cyber-crooks are using different website or subdomain names, so look out for suspicious email messages that are sent from email addresses ending with “onmicrosoft.com.” A lot of recipients of the spam and malicious email messages sent from Microsoft Office 365 or OnMicrosoft.com accounts created by scammers, cybercriminals or spammers, will think the email messages are legitimate because they are coming from “onmicrosoft.com,” which is owned and operated by Microsoft.

So, recipients of suspicious email messages that are sent from onmicrosoft.com or other email addresses, should never click on links in the suspicious emails to sign into their online accounts, should never send money or their personal information if they are asked to do so by suspicious emails, and should never respond to suspicious email messages.

I've received over 400 spams from and "...onmicrosoft.com email address in the past 2 months. After 50 of them I started sending spam notifications to

junk@office365.microsoft.com

abuse@microsoft.com

abuse@messaging.microsoft.com

abuse@frontbridge.com

Cert@Microsoft.com

The body of the notification contains this list of addresses.

Currently I've sent 139 notifications containing multiple spams to these email addresses. Microsoft seldom replies but when then do it's ALWAYS:

"...To report junk mail from Office 365 tenants, send an email to junk@office365.microsoft.com and include the junk mail as an attachment..."

What a bunch of IDIOTS! The very first email address in the list is junk@office365.microsoft.com!

I assume that they can't read English.

Received an email from noahsmith@t6usdy.onmicrosoft.com, the return address is noahsmith@redirecttheway.com, the email stated that I had compensation to claim due to a purchase I couldn't return or something. I have copied and pasted the full email in this for you guys to view and it may help someone else out there, who like me is broke and could easily have fallen for this, luckily I realised they don't mention the stores name at all, not only that I don't recall this ever happening where I had trouble returning an item let alone the last time I bought anything. Anyways here's the email...(I know it is but im hoping I'm not wrong)

NEW UPDATE: SUPPORT CASE #1684762866 DATED 22.05.2023

Dear Jodie ...,

I hope this message finds you well. I am reaching out regarding your support case from one year ago (22.05.2022), which, to our regret, remained unresolved due to a system malfunction. I was alerted to this oversight recently and immediately took the matter up with my superior, Richard.

Your initial complaint, lodged at our in-store service desk, involved an issue with a purchased item that you could not return or exchange. Unfortunately, the exact details of your case were also lost in the system error. This situation clearly contravenes our store policy, and we deeply regret any inconvenience this may have caused you.

To rectify this situation, we have determined to provide you with compensation. Given the duration of this issue, the compensation value will be significantly high. Please accept this as a token of our sincere apologies and as a testament to how much we value you as a customer.

To proceed, we need to confirm your email address: [email address removed]. Please respond to this email - your reply can be blank. As long as we receive your response, we can take the necessary steps to ensure you receive your rightful compensation.

Thank you for your understanding and cooperation.

Best regards,

Noah Smith

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
