Chinese language menace actors are weaponizing NFC expertise to steal funds from victims’ financial institution remotely accounts by means of refined Android malware campaigns, with safety researchers figuring out a minimum of $355,000 in fraudulent transactions from a single operation.
Group-IB researchers have uncovered a sprawling cybercrime ecosystem centered round NFC-enabled Android purposes that allow criminals to conduct unauthorized tap-to-pay transactions remotely.
Dubbed “Ghost Faucet,” these malicious purposes exploit Close to Discipline Communication expertise to relay fee information from victims’ units to attackers’ units, permitting them to empty financial institution accounts with out bodily entry to fee playing cards.
How the Assault Works
The Ghost Faucet scheme operates by means of a complicated relay mechanism involving two specialised purposes: a “reader” put in on the sufferer’s system and a “tapper” put in on the attacker’s system.
Criminals lure victims by means of smishing (SMS phishing) and vishing (voice phishing) campaigns, convincing them to put in malicious APK information and faucet their financial institution playing cards towards their Android units.
As soon as the sufferer’s card contacts the compromised cellphone, the malware captures the NFC fee information and relays it to the attacker’s system through command-and-control servers.
The cybercriminals then use fraudulently obtained point-of-sale terminals to money out the stolen funds, finishing transactions as if the sufferer’s card had been bodily current.
In various situations, criminals preload cellular wallets with compromised card particulars and deploy networks of mules throughout the globe to make purchases at bodily retail areas utilizing the modified tap-to-pay purposes.
Group-IB’s investigation recognized over 54 APK samples, with some malware variants masquerading as legit banking purposes.
The analysis uncovered three main malware distributors working inside Chinese language cybercrime communities on Telegram: TX-NFC, X-NFC, and NFU Pay.
TX-NFC, the biggest vendor recognized, established its Telegram channel in January 2025 and quickly gathered over 21,000 subscribers.
The group affords buyer assist in English and costs its malware from $45 for one-day entry as much as $1,050 for three-month subscriptions.
X-NFC emerged in December 2024 with over 5,000 members, whereas NFU Pay, regardless of having fewer subscribers, has its utility redistributed by different distributors beneath completely different names.
These distributors constantly evolve their choices, with NFU Pay reportedly offering personalized builds for particular international locations like Brazil and Italy, together with modifications that take away login necessities to facilitate sooner sufferer focusing on.
The applying has two exercise parts, the primary of which; “LoginActivity” handles consumer authentication and serves as the applying’s primary entrypoint:
Complementing the malware ecosystem is a thriving marketplace for illegitimately acquired POS terminals.
Oedipus, a Telegram channel affiliated with TX-NFC distributors, brazenly advertises POS terminals from monetary establishments throughout the Center East, Africa, and Asia.
Since November 2024, this single operation has processed roughly $355,000 in fraudulent transactions utilizing these stolen terminals.
Authorities worldwide have begun responding to this rising menace. Notable arrests embrace 11 Chinese language nationals apprehended in Knoxville, Tennessee in March 2025 for buying reward playing cards price tens of 1000’s of {dollars} utilizing these Android purposes marking the primary arrests of their type in the USA.
In November 2024, Singapore authorities arrested 5 people conducting contactless funds at high-value shops with out bodily playing cards. Czech police, Malaysian authorities, and Chinese language regulation enforcement have additionally made arrests associated to those NFC relay assaults.
The Visa Cost Ecosystem Danger and Management crew’s Spring 2025 Biannual Threats Report particularly highlighted the continued use of NFC-enabled malicious purposes for relay fraud, whereas Credit score China issued advisories detailing instances the place victims misplaced a minimum of $13,000 to those schemes.
Technical Evaluation
Safety researchers analyzing the malware found that purposes like TX-NFC are obfuscated and packed utilizing 360 Jiagu, a Chinese language business packer.
Based mostly on Group-IB Fraud Safety information tracked from Might 2024 to December 2025, we are able to observe a gradual improve within the detection of tap-to-pay malware samples.
The malware requests vital permissions together with NFC {hardware} entry, web connectivity, and foreground service capabilities to keep up persistence even when customers aren’t actively utilizing their units.
The purposes particularly goal ISO 14443 contactless fee playing cards and numerous NFC tag varieties.
Upon discovering an NFC-enabled fee card, the malware sends the “2PAY.SYS.DDF01” command to provoke communication with the Proximity Cost System Atmosphere, storing obtainable utility identifiers earlier than relaying all information by means of WebSocket providers to the attackers’ command-and-control infrastructure.
Code evaluation revealed that some variants are based mostly on NFCProxy, an open-source venture obtainable on GitHub, demonstrating how cybercriminals adapt legit applied sciences for malicious functions.
