A brand new variant of the TrickMo Android banking malware, delivered in campaigns focusing on customers throughout Europe, introduces new instructions and makes use of The Open Community (TON) for stealthy command-and-control communications.
The TrickMo banker was first noticed in September 2019 and has remained in lively growth, continuously receiving updates since then.
In October 2024, Zimperium analyzed 40 variants of the malware delivered through 16 droppers, speaking with 22 distinct command-and-control (C2) infrastructures, and focusing on delicate knowledge belonging to customers worldwide.
The newest variant was found by ThreatFabric, which tracks it as ‘Trickmo.C’. The researchers have been observing this model since January.
In a report at this time, ThreatFabric says that the malware is disguised as TikTok or streaming apps and targets banking and cryptocurrency wallets of customers in France, Italy, and Austria.
The important thing new characteristic within the present variant is the TON-based communication with the operator, which makes use of .ADNL addresses routed by way of an embedded native TON proxy working on the contaminated gadget.
TON is a decentralized peer-to-peer community initially developed across the Telegram ecosystem that enables units to speak with the online through an encrypted overlay community quite than publicly uncovered web servers.
TON makes use of a 256-bit identifier as an alternative of a standard area, which hides the IP handle and communication port, thus making the true server infrastructure harder to determine, block, or take down.
“Conventional area takedowns are largely ineffective as a result of the operator’s endpoints don’t depend on the general public DNS hierarchy and as an alternative exist as TON .adnl identities resolved contained in the overlay community itself,” explains ThreatFabric.
“Visitors-pattern detection on the community edge sees solely TON site visitors, which is encrypted and indistinguishable from some other TON-enabled software’s outbound move.”

TrickMo’s capabilities
TrickMo is a modular malware with a two-stage design: a bunch APK that serves because the loader and persistence layer, and a runtime-downloaded APK module that implements the offensive performance.
The malware targets banking credentials through phishing overlays, performs keylogging, display screen recording, and reside display screen streaming, SMS interception, OTP notification suppression, clipboard modification, notification filtering, and screenshot capturing.
ThreatFabric reviews that the brand new variant provides the next instructions and capabilities:
- curl
- dnsLookup
- ping
- telnet
- traceroute
- SSH tunneling
- distant port forwarding
- native port forwarding
- authenticated SOCKS5 proxy help
The researchers have additionally noticed the Pine runtime hooking framework, beforehand used to intercept networking and Firebase operations, however it’s at present inactive as there are not any hooks put in.
TrickMo additionally declares intensive NFC permissions and reviews NFC capabilities in telemetry, however the researchers didn’t discover any lively NFC performance.
Android customers are suggested to solely obtain software program from Google Play, restrict the variety of put in apps on their telephones, use apps solely from respected publishers, and make sure that Play Shield is lively always.
