Components of Ransomware Attacks in Office 365
Ransomware At the higher level, three main anatomies cause the most ransomware attacks:
Find a way in
The easiest method to trigger a ransomware attack is social engineering. It requires tricking an end user to open an email that has ransomware and malicious code. The ransomware attacks will masquerade as the link to software updates or as macros. Compromising the password of users or PII, and acting as an authorized user is a common technique for hackers to find a way into the organization.
Land & Expand
Once an organization’s system has been broken. Then, the ransomware virus is built to expand quickly and lock down as much of your system as possible. Ransomware can search critical files locally, on the network, and in the cloud. It contacts command and control services. After that, it can utilize access to spread it to other devices. With Office 365 and other cloud applications, ransomware can easily be transmitted through sharing. Moreover, collaboration tools like SharePoint Online and OneDrive for Business can spread ransomware among multiple systems, users, and shared documents.
Encrypt & Ransom
Ransomware is not similar to other types of malware. It will encrypt users’ files or lock down the system. Infected end-user machines will receive a message that their data has a ransomware virus. In such situations, hackers demand payment in cryptocurrency to unlock or release the system and data of victims. However, there is no guarantee that the hacker has not damaged your data or they will return control to your organization. User data may be destroyed and inaccessible even after the ransom has been paid.
Countering Ransomware in Microsoft 365 Environments
Ransomware represents a major danger to companies that rely on Microsoft 365, mainly because of its effects on Exchange Online, SharePoint Online, and other cloud services. Although ransomware isn’t specifically aimed at Microsoft 365 information, it can take advantage of the platform in various important ways:
OneDrive Syncing of Encrypted Files
Sometimes, ransomware locks up documents on personal computers and then copies them to Microsoft 365 through the OneDrive program. However, the copying process to the cloud is much slower than the encryption process on the local computer, often allowing only a small portion of the encrypted files to reach the cloud before someone notices the intrusion.
Limitations of Cloud Upload Speed
The upload speed to Microsoft 365 is short of being adequate for ransomware to successfully encrypt large-scale data on SharePoint and OneDrive. However, files that have been encrypted and uploaded to these accounts can usually be recovered through the versioning capabilities of Microsoft 365.
Microsoft 365 as an Entry Point
Hackers continue to use phishing emails as a common tactic to spread ransomware, exploiting Microsoft 365’s Outlook Online service to send infected files or links. For instance, Cerber ransomware targeted Microsoft 365 users by distributing harmful email attachments that bypassed the system’s security measures and infected computers upon opening.
Role in Lateral Movement
Once inside an organization, ransomware uses Microsoft 365 as its initial platform for additional spread and movement across the network. This involves collecting login details, examining the network, and taking advantage of weaknesses in the organization’s local network protocols to spread throughout the company.
SharePoint Online as a Secondary Vector
Although not as fast or dependable as alternative approaches, ransomware can spread via SharePoint Online by inserting infected files onto synchronized devices. This technique depends on individuals downloading these files onto susceptible machines to carry out the ransomware.
It’s important to understand that Microsoft 365 is not capable of running ransomware. Instead, it mainly acts as a storage medium for ransomware files, which need to be run on a computer to start the encryption process and spread throughout the network.
