Detects network communication with the Rokarolla trojan's command and control (C2) server ('beralisvc.info') and subsequent injection of base64-encoded HTML phishing overlays into legitimate banking application UIs. The rule identifies C2 contact via network events and the presence of specific HTML content indicators ('html_base64', 'PCFEt0NUWVBFIGh0bWw+', 'com.imaginbank.app') in HTTP responses, suggesting an overlay attack.
This query was originally published in the threat analytics report, EvilQuest signals the rise of Mac ransomware.

This query was originally published in the threat analytics report, Solorigate supply chain attack. Please note that these attacks are currently known as the Nobelium campaign.
Microsoft detects the 2020 SolarWinds supply chain attack implant and its other components as part of a campaign by the Nobelium activity group. Nobelium is the threat actor behind the attack against SolarWinds, which was previously referred to as Solorigate.
Nobelium silently added malicious code to legitimate software updates for Orion, which is IT monitoring software provided by SolarWinds. In this way, malicious dynamic link libraries (DLLs) were distributed to SolarWinds customers.
The following query locates malicious Nobelium-associated DLLs that have been created in the system or locally.
More Nobelium-related queries can be found listed under the See also section of this document.
