The Nigerian Communications Commission (NCC) has alerted the public on an ongoing cyber-vulnerability that allows a nearby hacker to unlock vehicles, wirelessly start their engines and steal or go away with the cars.
In a statement issued on Sunday on the latest threat to vehicle owners, the commission pointed out that the fact that car remotes are categorized short range devices that make use of radio frequency (RF) to lock and unlock cars necessitated the need for it to alert the general public on this emergent danger, in which hackers take advantage to unlock and start a compromised car
According to the latest advisory released by the Computer Security Incident Response Team (CSIRT), the Cybersecurity Centre for the telecom sector established by the NCC, the vulnerability is a Man-in-the-Middle (MitM) attack or, more specifically, a replay attack in which an attacker intercepts the RF signals normally sent from a remote key fob to the car, manipulates these signals, and re-sends them later to unlock the car at will.
The NCC further stated that with this latest type of cyber-attack, it is also possible to manipulate the captured commands and re-transmit them to achieve a different outcome altogether.
The advisory expatiated: “Multiple researchers disclosed a vulnerability, which is said to be used by a nearby attacker to unlock some Honda and Acura car models and start their engines wirelessly.
The attack consists of a threat actor capturing the radio frequency (RF) signals sent from your key fob to the car and resending these signals to take control of your car’s remote keyless entry system,” it stressed
However, the NCC-CSIRT, in the advisory, has offer some precautionary measures or solutions that can be adopted by car owners to prevent falling victim to the attack.
According to the cyber-alert unit of the Commission, “When affected, the only mitigation is to reset your key fob at the dealership. Besides, the affected car manufacturer may provide a security mechanism that generate fresh codes for each authentication request, this makes it difficult for an attacker to ‘replay’ the codes thereafter. Additionally, vulnerable car users should store their key fobs in signal-blocking ‘Faraday pouches’ when not in use.”
Importantly, car owners in the stated categories are advised to choose Passive Keyless Entry (PKE) as opposed to Remote Keyless Entry (RKE), which would make it harder for an attacker to read the signal due to the fact that criminals would need to be at close proximity to carry out their nefarious acts.
In a related advisory, the NCC, based on another detection by CSIRT, also alerted the public about the resurgence of Joker Trojan-Infected Android Apps on Google Play Store, stating that this arose due to the activities of criminals who intentionally download legitimate apps from the Play Store, modify them by embedding the Trojan malware and then uploading the app back to the Play Store with a new name.
The commission further states that the malicious payload is only activated once the apps goes live on the Play Store, which enables the apps to scale through Google’s strict evaluation process. Once installed, these apps request for permissions that once granted, enable the apps to have access to critical functions such as text messages and notifications.
As a consequence, a compromised device will subscribe unwitting users to premium services, billing them for services that do not exist. A device like this can also be used to commit Short Messaging Service (SMS) fraud while the owner is unaware.
The commission stated that to avoid falling victim to the manipulation of hackers deploying Joker Trojan-Infected Android Apps, Android users should avoid downloading unnecessary apps or installing apps from unofficial sources.
