In a recent cybersecurity incident, the Akira ransomware group demonstrated its evolving tactics by exploiting an unsecured webcam to bypass Endpoint Detection and Response (EDR) tools.
This novel approach highlights the group’s ability to adapt and evade traditional security measures, making it a formidable threat in the cybersecurity landscape.
Background and Modus Operandi
Akira, a well-established ransomware group, was responsible for 15% of the incidents responded to by the S-RM team in 2024.

Typically, Akira’s attacks involve compromising a network through externally facing remote access solutions and deploying tools like AnyDesk.exe to maintain access.
The group often uses Remote Desktop Protocol (RDP) to move laterally within the network, blending in with legitimate system administrator activities.
In a recent incident, Akira attempted to deploy ransomware on a Windows server via a password-protected zip file, but the EDR tool detected and quarantined the file, thwarting the initial attempt.
Evading EDR with IoT Devices
Faced with the EDR’s defenses, Akira pivoted its strategy by conducting an internal network scan to identify vulnerable devices.
The scan revealed several Internet of Things (IoT) devices, including webcams and a fingerprint scanner.
Akira targeted a webcam due to its critical vulnerabilities, lightweight Linux operating system, and lack of EDR protection.
The webcam’s limited storage capacity made it unlikely to support EDR tools, leaving it exposed.
By compromising the webcam, Akira successfully deployed its Linux-based ransomware, exploiting the device’s remote shell capabilities and unmonitored status to encrypt files across the victim’s network.
According to researchers, this incident underscores the importance of comprehensive security practices.
Organizations should prioritize patching and managing IoT devices, regularly auditing internal networks for vulnerabilities, and implementing network segmentation to isolate IoT devices from critical systems.
Monitoring network traffic from IoT devices for anomalies is also crucial.
The Akira attack highlights that even seemingly insignificant devices can become critical entry points for threat actors, emphasizing the need for a holistic security approach that includes all network-connected devices.
By adopting these measures, organizations can better protect themselves against evolving ransomware threats like Akira.
