Permanent link Tool: PowerShower

NamesPowerShower
CategoryMalware
TypeReconnaissance, Downloader
Description(Palo Alto) POWERSHOWER acts as an initial reconnaissance foothold and is almost certainly used to download and execute a secondary payload with a more complete set of features. By only using this simple backdoor to establish a foothold, the attacker can hold back their most sophisticated and complex malware for later stages, making them less likely to be detected.

In a nutshell, POWERSHOWER allows the attacker to:

• Fingerprint the machine, and upload this information to the initial C&C.
• Clean up a significant amount of forensic evidence from the dropper process, as we detail below.
• Run a secondary payload, if the attacker decides the target machine is sufficiently interesting (based on analysis of the system data sent from the first beacon)
