Additionally, hackers can establish local user access without administrative privileges by downloading portable executables of RMM software, bypassing software controls and risk management assumptions. By exploiting the features and functionalities of legitimate RMM software like ScreenConnect and AnyDesk, hackers can establish a connection with the victim’s system and gain control over their bank accounts. The manipulation of trust and the misuse of RMM software are key elements in these malicious attacks.
Refund Scam Techniques
Refund scam techniques involve establishing a connection with the victim’s system through the misuse of trusted remote monitoring and management (RMM) tools, enabling manipulation of the victim’s bank account. Hackers exploit the capabilities of RMM software to deceive victims into logging into their bank accounts while connected to the compromised system. Once the connection is established, the hackers modify the recipient’s bank account summary to display an excess refund. The victim is then instructed to refund the excess amount to the scam operator, unknowingly transferring funds to the hackers. By leveraging the access provided by RMM software, hackers gain control over the victim’s bank account and execute financial fraud techniques. These refund scam techniques specifically target victims by exploiting their trust in RMM software and their lack of awareness regarding such fraudulent activities.
Threats of Malicious RMM Software
Threats associated with the use of RMM software include the potential bypassing of administrative privileges and software controls, as well as the evasion of antivirus and antimalware protections. Hackers can exploit the portable executable feature of RMM software to establish local user access without triggering security measures. This allows them to gain control over systems and networks, bypassing the need for administrative privileges and circumventing software management control policies. Additionally, RMM software often evades traditional antivirus and antimalware protections, making it difficult to detect and mitigate malicious activities. To address these threats, effective detection techniques such as comprehensive intrusion detection systems like EINSTEIN can be employed. Prevention strategies should include implementing additional security measures, such as network segmentation, regular software updates, and user training to mitigate the risks associated with RMM software.
Targeting MSPs
Targeting Managed Service Providers (MSPs), threat actors frequently focus on authorized users of RMM software, utilizing trust relationships to gain access to a larger number of victims. MSPs, who frequently rely on legitimate RMM software for network administration and IT support tasks, become prime targets for these malicious actors. By compromising an MSP’s network, hackers can exploit the trust relationships established with the MSP’s customers.
