Protecting Microsoft Office 365 Web Apps

How it works
Man Working Remote From His Kitchen

Remote working is essential but risky

Remote access to company information is offered to an increasing number of employees. This trend is causing some serious security issues that are not mitigated by the standard security measures like anti-virus, authentication and encryption.

Sophisticated malware are targeting remote sessions in order to steal and spy on sensitive information. Malware spreads when end-users download or install an infected software or through phishing emails and links.

Malware threats

A legitimate user has read/write access to business data. This means that malware being able to hijack an application gains the same access and the same control as the actual user. And, the accessed data is available unencrypted.

This problem is independent from most likely installed security measures as SSL/VPN, Anti-Virus, and authentication solutions like 2-factor authentication, because the actual session is initiated by a legitimate user and the encrypted data is decrypted according to the implemented protocols.


Malware on infected end-points can steal, spy on or manipulate sensitive information being used or accessed from the client side. If an authentication token is used, the malware simply waits for the user to authenticate and then happily copies or changes information as the employee continues his work inside the application.

Man-in-the-middle attacks

By controlling the application from the inside, malware can easily operate as a man-in-the-middle copying or changing data, before it is encrypted and send to the server (as is the case for SSL/VPN solutions). Also, keylogging becomes trivial once the malware controls the application.


On an infected end-point, keyloggers can harvest sensitive information and send it to a central command and control server. Screenshots, either taken by the user (employee) or malware, may also lead to sensitive information getting into the wrong hands.
