How to remove NGate malware from your Android device

Also Known As: NGate virus
Type: Trojan
Damage level: Severe

What kind of malware is NGate?

NGate is an Android-specific malware. The goal of this software is to enable cyber criminals to make ATM withdrawals from victims' bank accounts. However, the technique used by NGate to facilitate this activity could be used for other malicious purposes.

At the time of writing, this malware was used to target customers of three Czech banks, including Czech Raiffeisenbank and ČSOB (Československá obchodní banka). Six variants of NGate have been discovered, each disguised to match the targeted bank. One associated with this campaign was arrested when withdrawing funds from ATMs in Prague.

NGate malware overview

NGate is known to infiltrate Android devices through smishing (SMS phishing) campaigns that rely heavily on social engineering tactics. Once the malware is opened, it presents the victim with a fake banking page. NGate relies on PWAs or WebAPKs to create imitator apps; more on this technique can be read in our article on the Spy.Banker malware.

The fraudulent page asks the recipient to enter their data and enable the NFC feature on their device. Targeted information can include the victim's banking account log-in credentials, date of birth, and debit/credit card PIN number. NFC (Near-Field Communication) is the protocol that NGate abuses to facilitate ATM withdrawals.

This communication protocol is used to transfer data between two devices. The malware uses a tool called NFCGate to relay NFC signals via a server to the attacker's Android device, which is prepped to imitate the victim's phone. Through socially-engineered communication, the victim is instructed to place their bank card on their phone.

Essentially, this is the process of linking a card to a smartphone, which would then enable the user to make contactless payments with their phone. What NGate does is send this NFC data to the attacker's device, thus linking the card to it. The cyber criminal can use the phone with the emulated bank card to withdraw the victim's money via an ATM. It is noteworthy that NGate can also be used to alter the withdrawal limit set on the card/account.

If the NFC method fails, the malware has a backup protocol wherein the funds are transferred to a different bank account. It is a less desirable scenario, as bank transfers are more traceable.

As mentioned in the introduction, NGate and its ability to abuse NFC signals to mimic the victim's phone (and linked content) could be used for a variety of nefarious deeds. It is also worth noting that malware developers often improve upon their software and methodologies. Therefore, potential future variants of NGate could have additional/different capabilities or be used for other purposes.

To summarize, the presence of software like NGate on devices can result in severe privacy issues, significant financial losses, and identity theft.

Android-specific malware examples

We have written about countless malicious programs; LianSpyBlankBotBingoMod, and GuardZoo are just a few examples of ones targeting Android operating systems.

Malware is a broad term encompassing programs with various harmful abilities and purposes. However, regardless of how malicious software operates – its presence on a system threatens device and user safety. Therefore, all threats must be removed immediately upon detection.

How did NGate infiltrate my device?

The known NGate campaign began with spam SMSes likely sent at random (smishing). The text message concerned a tax return, but other lures are likely. The SMS leads to a malicious page impersonating the online bank website, from which the victim downloads NGate.

Once accessed, the malware (disguised as a bank app) requests the user to provide their banking information (like log-in credentials). After that is done, the victim is contacted by cyber criminals who pretend to be the official support of their bank. They claim that the device was compromised and provide the victim instructions, such as changing their PIN (by entering the old one into the imitator app – NGate) and placing their bank card on the phone (e.g., for verification purposes).

However, NGate could operate in different ways, and this applies to the methods used to proliferate it.

Malware is usually disguised as or bundled with ordinary software/media. Widespread distribution techniques include: malicious attachments/links in spam (e.g., SMSes, emails, PMs/DMs, social media posts, etc.), drive-by downloads, dubious download channels (e.g., freeware and free file-hosting sites, P2P sharing networks, third-party app stores, etc.), online scams, pirated content, illegal software activation tools ("cracks"), and fake updates.

Some malicious programs can even self-spread via local networks and removable storage devices (e.g., external hard drives, USB flash drives, etc.).

How to avoid installation of malware?

We highly recommend researching software before downloading/purchasing by reading terms and expert/user reviews, checking necessary permissions, and verifying developer legitimacy. All downloads must be made from official and verified sources. Software must be activated and updated using genuine functions/tools, as those obtained from third-parties can contain malware.

Another recommendation is to be vigilant when browsing since fraudulent and malicious online content usually appears legitimate and harmless. We advise caution with incoming emails, PMs/DMs, SMSes, etc. Attachments or links found in suspicious/irrelevant messages must not be opened, as they can be virulent.

It is paramount to have a dependable anti-virus installed and kept updated. Security programs must be used to run regular system scans and to remove detected threats and issues.
