Short bio
Trojan.Remcos is Malwarebytes’ detection name for a Remote Administration Tool (RAT) targeting Windows systems.
Type of infection
Trojan.Remcos typically infects a system by embedding a specially-crafted settings file into an Office document, this allows an attacker can trick a user to run malicious code without any further warning or notification. The code is XML code which allows for any binary with parameters to be executed. This code is used to download and execute the REMCOS RAT.
Aftermath
Trojan.Remcos gives the threat actor full control over the infected system and allows them to run keyloggers and surveillance (audio + screenshots) mode. This means:
- Data/information about the system may have been stolen
- User credentials may have been stolen
- Digital coins may have been stolen
- Affected system may be susceptible to further attacks and/or infection due to a backdoor that was opened
