On 12 January 2026, a cybersecurity incident called "Sophisticated Voicemail-Themed Social Engineering Campaign Deploys Remote Access Tools" came to light.
A newly uncovered social engineering campaign is leveraging fake voicemail notifications to trick victims into installing remote access tools, granting attackers persistent control over compromised systems.
The disruption is felt across the environment, affecting 86 web properties compromised.
Formal response steps have not been shared publicly yet.
The case underscores how teams are taking away lessons such as The campaign highlights the effectiveness of psychological manipulation in social engineering attacks, combining familiar themes (voicemail notifications) with legitimate tools (Remotely RMM) to evade detection. Multi-stage deception, including audio playback as a distraction, reinforces the illusion of legitimacy, and recommending next steps like Organizations should enhance employee training to recognize social engineering tactics, implement strict controls on remote access tool installations, and monitor for unusual C2 server communications. Additionally, verifying the legitimacy of voicemail notifications and other routine communications can reduce risk.
Finally, we try to match the incident with the MITRE ATT&CK framework to see if there is any correlation between the incident and the MITRE ATT&CK framework.
The MITRE ATT&CK framework is a knowledge base of techniques and sub-techniques that are used to describe the tactics and procedures of cyber adversaries. It is a powerful tool for understanding the threat landscape and for developing effective defense strategies.
