Microsoft leads brand phishing attacks in Q3 2026

Check Point Research reported that Microsoft was the most impersonated brand in phishing attacks during the third quarter of 2026, accounting for 33% of all brand‑based attempts. This share rose from 23% in the previous quarter and was roughly four times higher than any other brand on the list.

Apple and Google each represented about 8% of the impersonation attempts, placing them well behind Microsoft. Dropbox and YouTube showed the largest increases in their ranking among the top ten most spoofed brands.

The report explains that attackers prefer Microsoft because a stolen Microsoft credential can give access to a wide range of services, including Office 365, Azure cloud resources, and personal Outlook accounts. Once a credential is compromised, cybercriminals can move laterally across an organization’s network or harvest additional data from linked services.

Anyone who uses Microsoft accounts for work or personal purposes is potentially at risk. The phishing emails typically mimic official Microsoft communications, using familiar logos and language to trick recipients into entering their login details on a fake site. The fraudulent sites are often designed to look identical to Microsoft’s legitimate login pages, making it difficult for users to spot the difference.

To reduce the chance of falling victim, users should verify the sender’s address, hover over links to see the actual URL, and avoid entering credentials on any page that does not use https and display the correct Microsoft domain. Enabling multi‑factor authentication adds an extra layer of protection, as it requires a second verification step even if a password is compromised. Users can also run suspicious emails through the free email checker on ComputerScams.com to see if the message is known to be malicious.

If you suspect that you have entered your Microsoft credentials on a fake site, change the password immediately and review account activity for unknown logins. Report the phishing email to Microsoft’s phishing‑report address and consider notifying your organization’s IT security team.

A practical step you can take right now is to enable multi‑factor authentication on all your Microsoft accounts, which significantly lowers the risk of unauthorized access.
