Work From Home in 2020

Working from Home in 2020: Threat Actors Target the Cloud

Like any enterprise, cybercrime focuses its resources where it can derive value, which is data. In the case of ransomware, data is held hostage for a direct monetary exchange, whereas many other data breaches seek to steal data and monetize it on dark web markets. These two methods are even starting to merge, with some cybercrime organizations now offering Data-Leaking-as-a-Service. For most of the history of cybercrime, resources and infrastructure used to steal data targeted endpoint devices and network stores, using malware to land an attack, find data, and exfiltrate. That’s where the data was.

Now, we have a dramatic shift of data moving to cloud service providers, held not within the confines of a customer’s managed network but instead a third party. The shift to working from home in early 2020 accelerated cloud use, just as it accelerated other trends like food delivery and telehealth.

With the acceleration of cloud adoption comes more data in the cloud, and in lockstep, threat actors shifting their attack resources to the cloud. Through the first months of 2020 as this shift occurred, we monitored attack attempts from external threat actors on our customer’s cloud accounts, which increased 630%: 

Total Cloud Threats

In this chart, we’ve plotted all threats across 30 million cloud end users, along with the two primary categories of external threat events targeted at cloud accounts. They are: 

  • Excessive Usage from Anomalous Location. This begins with a login from a location that has not been previously detected and is anomalous to the user’s organization. The threat actor then initiates high-volume data access and/or privileged access activity.  
  • Suspicious Superhuman. This is a login attempt from more than one geographically distant location, impossible to travel to within a given period of time. We track this across multiple cloud services, for example, if a user attempts to log into Microsoft 365 in Singapore, then logs into Slack in California five minutes later. 

The increase in threat events impacted some verticals more than others, with companies in Transportation/Logistics, Education, and Government agencies hit the hardest:
