Cybercriminals bribed insiders to implant a Raspberry Pi on an Indonesian bank's network, enabling remote ATM cash withdrawals through sophisticated, undocumented techniques. The attack, attributed to threat group UNC2891, bypassed traditional defenses using a 4G modem and Linux backdoors, highlighting critical gaps in physical and network security.

Hackers infiltrated a bank's network by physically planting a 4G-enabled Raspberry Pi on an ATM switch, creating an invisible backdoor for lateral movement and fraud attempts. The UNC2891 group leveraged custom anti-forensic techniques to mimic legitimate processes while attempting to deploy ATM-spoofing malware. This sophisticated hybrid attack underscores critical vulnerabilities in financial institutions' physical and digital security postures.
