Office 365 beefs up anti-phishing measures

Posted on Tuesday October 30, 2018

There are plenty of things to love about Office 365. For a small monthly fee, it gives you the latest cloud-based version of Microsoft Office apps and robust communication tools that improve collaboration and productivity. But it's also an extremely secure platform that can defend against the most cunning phishing attacks.

Effective anti-phishing solutions must be able to recognize the key elements of a phishing attack, which includes spoofed (or forged) emails, compromised accounts, unsafe links, and harmful attachments. In April 2018, Microsoft upgraded Office 365's Advanced Threat Protection (ATP) features so it can better detect these elements and prevent a wide variety of phishing scams. These enhancements include:

• Anti-impersonation measures - ATP will now look for potential phishing indicators in an email, including the sender's address, name, and links, to identify whether the user is being impersonated. You can specify high-profile targets within your organization, such as managers and C-level executives, so Office 365 can protect these users from email impersonation. Office 365 also utilizes machine learning to analyze a user's email patterns and flag suspicious contacts that have had no prior correspondence with your company.
• Anti-spoofing technology - This feature reviews and blocks senders that disguise their true email address. You can even enable safety tips that flag certain email domains that have strange characters. For instance, if your real domain is Acme.com, a spoofed domain could be Acḿe.com.
• Email link scanning - Office 365 launched Safe Links, which scans emails for fraudulent links and redirects users to a safe page in case it does contain harmful materials. This feature also applies to email attachments, ensuring you're protected against all types of phishing scams.

Due to these improvements, Office 365 had the lowest phish rate among other well-known email services between May 1 and September 16, 2018. The company has stopped over five billion phishing attempts and protected users against seven billion potentially malicious links. If you're looking for a secure email platform, Office 365 is the best option for your business.

That said, it's not a substitute for good security awareness. No matter how secure Office 365 is, employees still need to be adequately trained to recognize a phishing email when they see one. Hackers are constantly changing their tactics to evade Office 365's detection systems, so it's important that everyone is alert at all times.
