Microsoft Office 365 Anti Phishing is Critical

Stopping phishing with Microsoft 365 is important as more businesses move to the cloud and Microsoft Office 365 usage grows by more than 50%.

We will discuss how Microsoft 365 can be used to stop phishing email, and other tools that can be used to put an end to phishing email.

From Spear Phishing, to Whaling

Understanding the various types of phishing emails such as social engineering and spear phishing is important. Each one has a unique set of characteristics and each requires a different response in order to stop phishing emails. These are the most popular types of phishing emails:

  • Simple phishing
  • Phishing with sophistication
  • Phishing is a serious problem
  • Whale watching

Simple phishing emails

Simple phishing emails were really easy: A Nigerian prince who really needed your assistance, or someone you know who is stuck in Thailand with their bank account stolen. The simple phishing emails are now slightly more sophisticated and include competition winners (yes, people still click those), mailboxes full of phishing email, password expired and so forth.

Phishing emails that are sophisticated

These attacks are more sophisticated than simple phishing emails and contain more carefully-planned elements. This is a common example. The threatening email claims that they have video evidence that you are watching por no graphy. Send us bitcoin or we’ll send the videos to your contacts. Phishing emails are more complex because they often start by quoting your real passphrase (which they purchased online from another data breach). You can also use document-based phishing emails like Google Docs, Dropbox links, or Microsoft OneDrive messages. These emails look legit and hide their links well.

Spear Phishing

These are targeted phishing attacks against a particular person or group. The attacker will usually have done some research on LinkedIn to find the victim’s name, email address, and that of a boss/colleague. The attacker will then send a targeted, phishing email posing as from a trusted source and asking for information that is relevant to the victim’s job. A CEO might send a targeted phishing email to a CFO about a “secret project” and ask for money “urgently”.

Whale watching

Then there is whaling. When attackers target the top brass of an organization, such as the CEO or Chairman. The message is often carefully written and meticulously researched. Too many of these attacks have failed, leading to firings and data breaches.

Social Engineering

Many of these forms of phishing share a common trait: some form of social engineering. Social Engineering The use of deception to get people to divulge personal or confidential information in order for fraud purposes. As we examine Microsoft Office 365, social engineering will be a key component to protecting your company and users from phishing emails.

Microsoft Office ATP

Microsoft ATP (or “advanced threat protection”) is not to be confused the world tennis tour. It provides an additional layer of security for stopping fake email.

Microsoft Outlook to Stop Phishing Emails

Microsoft Outlook has built-in tools to help you stop phishing emails. Click “File” from your administrator account and then “Rules & Alerts”. You can create your own rules and alerts to give you some control over your email. This allows you to, for instance, move emails containing a particular word in the subject into a folder. If you receive phishing emails that have the subject “You’ve Won An iPhone!” you can move them to junk.

Managing rules and alerts in Microsoft Outlook

You can also set up alerts to be notified of mass emails and potential attacks in these cases.

Junk is often thought of as the final stop for bad email. However, it can be a very powerful tool when used properly. You can create rules, such as safe or blocked senders, to give you at least some influence over what emails are delivered to your inbox and to other users.

Using Junk folder options to create rules
