In a concerning development, the notorious Emotet malware now installs Cobalt Strike beacons directly, giving immediate network access to threat actors and making ransomware attacks imminent.

Emotet is a malware infection that spreads through spam emails containing malicious Word or Excel documents. These documents utilize macros to download and install the Emotet Trojan on a victim's computer, which is then used to steal email and deploy further malware on the device.

Historically, Emotet would install the TrickBot or Qbot trojans on infected devices. These Trojans would eventually deploy Cobalt Strike on an infected device or perform other malicious behavior.

Cobalt Strike is a legitimate penetration testing toolkit that allows attackers to deploy "beacons" on compromised devices to perform remote network surveillance or execute further commands.

However, Cobalt Strike is very popular among threat actors who use cracked versions as part of their network breaches and is commonly used in ransomware attacks.
