Cloud App Adoption

Cloud apps are ubiquitous in the enterprise, with the average user interacting with 24 different cloud apps every month. The top six apps make it clear the big preference for Microsoft apps in the Insurance industry. These specific apps were not only the most used, but also cover a big variety of functionalities such as storage, email, and messaging.

Apps like Microsoft Teams, OneDrive, and SharePoint are common in most industries, but Insurance stands out with Microsoft apps dominating the top six.

With so many cloud apps in use, especially the combinations of enterprise and personal apps, it underscores the importance of organizations in Insurance having policies to ensure the safe handling of sensitive data.

Cloud Apps Abused for Malware Delivery

Because adversaries deliver malware through many different channels, organizations in Insurance must ensure that they have security controls to block malware downloads over the most popular apps. Approximately half of all global HTTP/HTTPS malware downloads originate from popular cloud apps, with the other half originating from different locations on the web. This section highlights the apps with the most malware downloads that were blocked by Netskope over the past year.

The most popular apps around the world are also among the top apps in terms of the number of malware downloads, reflecting adversary tactics (adversaries tend to abuse top apps because of their popularity), user behavior (users interact with popular apps more frequently), and organizational policy (organizations tend to allow popular apps). The top two apps with the most malware downloads, GitHub and OneDrive, have very similar numbers in terms of malware downloads.

Top Malware Families

This list contains the top five malware and ransomware families detected by Netskope targeting users in Insurance over the last 12 months:

Backdoor.Zusy (a.k.a. TinyBanker) is a banking Trojan based on the source code of Zeus, aiming to steal personal information via code injection into websites.
Downloader.BanLoad is a Java-based downloader widely used to deliver a variety of malware payloads, especially banking Trojans.
Infostealer.AgentTesla is a .NET-based RAT with many capabilities, such as stealing browsers’ passwords, capturing keystrokes, clipboard, etc.
Trojan.Grandoreiro is a LATAM banking trojan with the goal of stealing sensitive banking information, commonly targeting Brazil, Mexico, Spain, and Peru.
Phishing.PhishingX is a malicious PDF file used as part of a phishing campaign to redirect victims to a phishing page.

Recommendations

This report highlights increasing cloud adoption, including increased data uploaded to, and downloaded from, various cloud apps. It also highlights an increasing trend of attackers abusing various cloud apps, especially popular enterprise apps, to deliver malware (mostly Trojans) to their victims. Netskope Threat Labs recommends organizations in Insurance review their security posture to ensure that they are adequately protected against these trends:

Inspect all HTTP and HTTPS downloads, including all web and cloud traffic, to prevent malware from infiltrating your network. Netskope customers can configure their Netskope NG-SWG with a Threat Protection policy that applies to downloads from all categories and applies to all file types.
Ensure that high-risk file types like executables and archives are thoroughly inspected using a combination of static and dynamic analysis before being downloaded. Netskope Advanced Threat Protection customers can use a Patient Zero Prevention Policy to hold downloads until they have been fully inspected.
Configure policies to block downloads from apps and instances that are not used in your organization to reduce your risk surface to only those apps and instances that are necessary for the business.
Configure policies to block uploads to apps and instances that are not used in your organization to reduce the risk of accidental or deliberate data exposure from insiders or abuse by attackers.
Use an Intrusion Prevention System (IPS) that can identify and block malicious traffic patterns, such as command and control traffic associated with popular malware. Blocking this type of communication can prevent further damage by limiting the attacker’s ability to perform additional actions.
Use Remote Browser Isolation (RBI) technology to provide additional protection when there is a need to visit websites that fall into categories that can present higher risk, like newly observed and newly registered domains.
