Spear-Phishing Attacks Targeting Office 365 Users, SaaS Applications

10/01/2020
by Admin Admin

Over the course of the last 15 years, cyber threats have gone from urban myths and corporate ghost stories to as mainstream as carjackings and burglaries. There isn’t a business owner of a small restaurant chain or a CEO of a Fortune 500 company who doesn’t think about the fallout of being breached.

I’m not here to tell you how the threats are getting more sophisticated, or how state-sponsored hacker groups are getting more and more funding; you already know that. But what I do want to share with you is something that I’m seeing daily. Targeted threats that you may have already witnessed and, unfortunately, been personally a victim of or know someone who has: Spear-phishing.

Are you an Office 365 user? Do you have customers who are Office 365 users? Are you a managed security service provider (MSSP) that administrators Office 365 for your clients? You probably need a solution that applies effective Office 365 security capabilities and controls.

With close to 200 million global users, Office 365 is a target — a big target. And spear-phishing attempts are good. Really good. Recently, Forbes ran a summary of the threat. Alarmingly, today’s most advanced spear-phishing attempts look like they come from your CFO, boss or trusted vendor. They provide credibility to the target and, many times, users take the bait. Money gets wired. Access to accounts are provided. Confidential information is exposed.

Traditional email security isn’t enough protection. Out-of-the-box, cloud-native security services aren’t enough protection. A lean, effective and modern Office 365 security or SaaS security solution is required.

How to stop spear-phishing attacks, advanced cyber threats

SonicWall Cloud App Security (CAS) combines advanced security for Office 365, G Suite and other top SaaS applications to protect users and data within cloud applications, including email, messaging, file sharing and file storage. This approach delivers advanced threat protection against targeted email threats like phishing attacks, business email compromise, zero-day threats, data loss and account takeovers.

CAS also seamlessly integrates with sanctioned SaaS applications using native APIs. This helps organizations deploy email security and CASB functionalities that are critical to protecting the SaaS landscape and ensure consistent policies across cloud applications being used.

Explore the five key reasons CAS may be able to protect your organization from spear-phishing and other advanced attacks.

  • CAS delivers next-gen security for Office 365, protecting email, data and user credentials from advanced threats (including advanced phishing) while ensuring compliance in the cloud
  • Monitor SaaS accounts for IOCs, such data leakage, account takeover, business email compromise (BEC) and fraud attempts
  • Block malware propagation in malicious email attachments and files, whether they are at-rest or traversing a SaaS environment, internally or cloud-to-cloud
  • Prevent data breaches using machine learning and/or AI-based user profiling and behavior analytics for incident detections and automated responses
  • Leverage Shadow IT to monitor cloud usage in real time, and set policies to block unsanctioned applications

In my over 10 years of observing various attacks and sitting in rooms with customers (not mine, fortunately) who have been breached, I can tell you that you don’t want it ever to be you or your customers. This threat is having more success than any I’ve seen — and they are very recent.
