Researchers have uncovered a complicated marketing campaign leveraging the Lampion banking trojan, a malware pressure that has operated since 2019 with a renewed concentrate on Portuguese monetary establishments.
The risk actor group behind these operations has refined its ways considerably, introducing novel social engineering methods that make conventional detection more and more tough.
What distinguishes this newest iteration is the combination of ClickFix lures, a misleading methodology that convinces customers they should repair technical points earlier than executing malicious payloads.
The an infection vector begins with rigorously crafted phishing emails mimicking authentic financial institution switch notifications.
Risk actors use compromised e-mail accounts to distribute these messages, lending them authenticity that informal inspection may miss.
The emails comprise ZIP file attachments quite than direct hyperlinks, a tactical shift applied round mid-September 2024 that demonstrates the group’s adaptive method to bypassing safety controls.
Bitsight analysts recognized the marketing campaign’s evolution throughout three distinct time intervals, with essentially the most notable transformation occurring in mid-December 2024 when ClickFix social engineering entered the assault chain.
An infection chain (Supply – Bitsight)
The researchers documented the malware’s energetic an infection fee within the a number of dozens each day, with lots of of energetic compromised techniques at present underneath attacker management.
This scale displays the marketing campaign’s effectiveness and the group’s operational sophistication. The an infection chain reveals a multi-stage structure designed to evade detection at every step.
After victims obtain the deceptively labeled attachment, they encounter what seems to be a authentic Home windows error notification, full with acquainted UI parts.
New ClickFix lure (Supply – Bitsight)
This ClickFix lure prompts customers to click on hyperlinks that provoke the precise malware supply, making a false sense of safety whereas the an infection course of unfolds behind the scenes.
An infection Mechanism and Persistence Techniques
The technical infrastructure supporting this marketing campaign demonstrates appreciable experience in operational safety.
The an infection chain progresses by way of obfuscated Visible Fundamental scripts, every stage additional obfuscating the malicious intent till reaching the ultimate DLL payload containing the stealer performance.
Notably, persistence mechanisms have been added to the primary stage round June 2025, enabling the malware to outlive system reboots and keep entry throughout periods.
The risk actors make use of geographically distributed infrastructure spanning a number of cloud suppliers, successfully compartmentalizing their operations.
IP blacklisting capabilities inside their infrastructure stop safety researchers from tracing the whole an infection chain, whereas additionally enabling fine-grained management over which victims obtain which payloads.
Bitsight researchers famous that the lots of of distinctive samples at every an infection stage recommend automated technology, indicating the group possesses enough technical functionality to scale their operations effectively whereas sustaining operational safety all through the assault cycle.
