In the last 12 months, Microsoft OneDrive was the most popular cloud app abused for malware downloads in Latin American organizations, representing 21% of all cloud malware downloads. As highlighted earlier in this report, Microsoft OneDrive is also the most popular app among users in Latin America, which makes it both an useful app for attackers seeking to target a wide variety of organizations using the same toolset, and also makes it more likely that the malicious payloads would reach their targets.

Malware & Ransomware

Top Malware Types

The most common malware detected by Netskope in Latin America in the last twelve months were Trojans, which are commonly used by attackers to gain an initial foothold and deliver other types of malware, such as infostealers, remote access Trojans, backdoors, and ransomware. The second most common type of malware are downloaders, which, like Trojans, are also used to deliver other types of malware.

Rounding out the top three are backdoors. Like Trojans, some malware payloads blocked in this category can also fit other categories, because they provide not only clandestine remote access, but also keylogging, file manipulation, registry manipulation, and other malicious features. Malware in this category include Remcos, Quakbot, and NjRAT (a.k.a Bladabindi).

Recommendations

This report highlighted increasing cloud adoption, including increases of data being uploaded to and downloaded from a wide variety of cloud apps. It also highlighted an increasing trend of attackers abusing a wide variety of cloud apps, especially popular enterprise apps, to deliver malware to their victims. The malware samples were primarily Trojans, but also included downloaders, backdoors, file-based exploits, ransomware, and infostealers. Netskope Threat Labs recommends organizations in Latin America 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.

In addition to the recommendations above, Remote Browser Isolation (RBI) technology can 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.
