ZeroFOX Threat Research: Quarter 1 2021 Threat Report

The ZeroFOX Threat Research team is excited to announce the release of our Quarterly Threat Report for Q1 of 2021.

Link to Download

Report Summary

In the first quarter (Q1) of 2021, the global cyber threat landscape exhibited a series of events that included takedowns of criminal infrastructure, the persistence of ransomware extortion schemes, and creative tools and techniques used to deliver malicious artifacts to victims. Law enforcement agencies worldwide worked together to disrupt criminal operations in credit card networks, ransomware groups, and botnet infrastructure. The success of ransomware double extortion tactics led to the continuation of this method as new ransomware types emerged and operators used grey hat tactics to justify their criminal actions. Threat actors leveraged creative delivery tools and techniques that evade detection by security technologies and make analyzing cyber threats more complex.

In underground cyber communities, ZeroFOX Threat Research observed significant competition among threat actors due to increased traffic in marketplace networks. The investigation of the December 2020 SolarWinds Orion breach continued in Q1, with security researchers identifying six malware types used in the breach. Another large-scale attack took place against Microsoft Exchange Servers this quarter in which threat actors exploited a set of vulnerabilities to access target environments and install malware. Furthermore, four key industries faced cybersecurity risks due to COVID-19-themed threats, vulnerable infrastructure, and evolved technology. In this Quarterly Threat Landscape Review, ZeroFOX Research provides an overview and analysis of the prominent threats in Q1 2021.

BRATA Keeps Sneaking into Google Play, Now Targeting USA and Spain

The McAfee Mobile Research Team uncovered several new variants of the Android malware family BRATA being distributed in Google Play, ironically posing as app security scanners. First spotted at the end of 2018 and named “Brazilian Remote Access Tool Android” (BRATA) by Kaspersky, this “RAT” initially targeted users in Brazil and then rapidly evolved into a banking trojan.

FBI nuked web shells from hacked Exchange Servers without telling owners

A court-approved FBI operation was conducted to remove web shells from compromised US-based Microsoft Exchange servers without first notifying the servers' owners. On March 2nd, Microsoft released a series of Microsoft Exchange security updates for vulnerabilities actively exploited by a hacking group known as HAFNIUM. These vulnerabilities are collectively known as ProxyLogon and were used by threat actors in January and February to install web shells on compromised Exchange servers. The FBI requested this warrant because they believed that the owners of the still-compromised web servers did not have the technical ability to remove them on their own and that the shells posed a significant risk to the victim.

New WhatsApp Bugs Could've Let Attackers Hack Your Phone Remotely

Facebook-owned WhatsApp recently addressed two security vulnerabilities in its messaging app for Android that could have been exploited to execute malicious code remotely on the device and even compromise encrypted communications. The flaw (CVE-2021-24027) leverages Chrome's support for content providers in Android (via the "content://" URL scheme) and a same-origin policy bypass in the browser (CVE-2020-6516), thereby allowing an attacker to send a specially-crafted HTML file to a victim over WhatsApp, which, when opened on the browser, executes the code contained in HTML file. WhatsApp users are recommended to update to version 2.21.4.18 to mitigate the risk associated with the flaws.

100,000 Google Sites Used to Install SolarMarket RAT

Hackers are using search engine optimization (SEO) tactics to lure business users to more than 100,000 malicious Google sites that seem legitimate and install a remote access trojan (RAT), tracked as SolarMarker, to gain a foothold on a network and later infect systems with ransomware, credential-stealers, banking trojans, and other malware. SEO tactics direct users searching for common business forms such as invoices, receipts, or other templates to hacker-controlled Google-hosted domains. This is an increasingly common trend with malware delivery, which speaks to the improved security of applications such as browsers that handle vulnerable code.
