Malicious links being reported by Microsoft Office 365

Hello, we have had an issue develop in the last week or two where the links in our emails direct users to a "malicious website" warning from Microsoft Office 365. I should point out that this is not happening on emails going out via Hubspot, as far as I know, but rather through another email vendor that we use. Is anyone else experiencing this and if so, have you been able to find a resolution? Our vendor says they are actively working with Microsoft on this but the problem seems to be getting worse and not better. 

 

Thanks in advance.

We ended up filing an appeal with Microsoft to de-list our domain. It has happened twice and both times they rescanned our domain and called it a false positive. They really need to do a better job as it affects businesses when they falsely flag sites as malicious.

Hi @afu, can you tell from where you filed the appeal? It's pretty hard to find the right place from Microsoft 🙂

Our IT handles this for us. We're on O365. From our IT dept:

 

"These appeals are filed through the BMC O365 tenant under the Security section (https://security.microsoft.com/reports...).  From here you are able to submit emails, urls, or files to Microsoft for analysis.  Please let us know if you need anything else."

Today, we send an e-mail to our customer. There is a warning that there is a threat named FRAUD_SCAM.WRS in the link I shared the screenshot below. I request your help on the matter. malware.PNG

Yes, a ticket has been opened a few days ago, but no resolution yet.

Hello @afu, what is the specific malicious error you received on your end?

 

The more information, screenshots, and details you can provide, the better I can advise on the next steps.

 

Thank you,

Pam

Is there any update on this? We're using a connected domain (preview.bmcepartners.com) to circumvent the new requirement to be logged in to view Previews of marketing emails, however just recently, we started being flagged. This is hurting our reputation as a company and reliable sender of emails on behalf of our clients, as the end-URLs are NOT malicious. It is also presenting our customer is a very negative light.

 

Yes, we are using our own domain, but from the above it appears this is occuring for others using the Hubspot domain as well. This needs resolved ASAP.

This same thing happened to my company over the weekend. I have no idea what could possibly have triggered it and it's something I can't simply live with without a possible fix. I can't even share web links with my internal staff without those being flagged by Teams or Outlook. Is it HubSpot itself, a particular plugin/template, or something else that could be causing this?

Per today's in-app notification I notice this issue is reoccuring.  @hubspot, please can you confirm that if an email is NOT received by an intended recipient because of this problem that we, the sender, will receive an error message/notification?

Hi @MKjær @ean0723 @jjokinen @darshakparmar  @JonathanElkin  @MSouth  we're currently working with Microsoft on this right now as it seems they are flagging our links as malicious. 

 

I'll keep everyone updated on this as soon as we have news from our team and Microsoft. 

 

Thank you for your patience here.

As of now, I am not seeing any more emails being flagged as malicious. Thanks for fixing this.

Hi,

Since this was reported, our email open rates have dropped significantly. I'm concerned that the sending domain has been flagged as spam and our emails are ladning up in junk folders.

 

Has anyone else experienced similar open-rate issues this week?

Same issue here. A lot of our customers and potential customers are seeing this in emails sent out by us. Need an immediate fix. This is bad for the brand of any organization using HubSpot for 1:1 emails. Not to mention, risk of getting blocked on a permanent basis by the recipient's firewalls for sending such links.
