Research from Securonix shows the attack kicks off using fake emails made to look like Booking.com alerts. A supposed booking cancellation triggers the alert. Displayed boldly is a charge in euros - frequently more than €1,000. That sum aims straight at emotions, sparking alarm. Fear takes over, nudging people toward clicking before checking details.
Clicking the “See Details” button sends people nowhere near Booking.com. A hidden detour happens first - through another web address entirely. Then comes a counterfeit site built to trick. There, a phony CAPTCHA pops up out of nowhere. After that, a fake Blue Screen appears like it is urgent. Words flash: fix this now by clicking here. Those clicks run harmful PowerShell scripts without warning. The whole chain relies on looking real until it is too late.
Something begins before the main event - stages unfold slowly, one after another. A hidden rhythm runs through it all, tied to familiar parts of Windows, used in ways they were never meant to be. An XML file shows up without notice, slipped into place while no one watches. It looks harmless, built like a regular project for MSBuild.exe, which itself is real software from Microsoft. Instead of old tricks involving clunky HTML apps, attackers now twist everyday tools into something else.
What seems ordinary might already be working against you. Normal actions become cover, hiding intent inside routine noise.
A hidden DCRat program gets activated during execution. At the last step, a compressed .NET tool called staxs.exe unlocks its internal settings through advanced encryption like AES-256 paired with PBKDF2. To stay active across restarts, it drops a misleading Internet Shortcut into the Startup directory on Windows.
After turning on, DCRat reaches out to several hidden servers, then checks what kind of machine it has landed on. Information about the software, settings, and person using the device gets gathered piece by piece.
Remote operators gain complete control right after. Instead of running openly, it sneaks inside normal system tasks by reshaping them from within. That trick helps it stay put without drawing attention.
Noticing clues in the code, experts link the operation to hackers who speak Russian.
Built into everyday tools users trust, this malware plays on emotions while slipping past alarms. What stands out is how each step connects - carefully strung - to avoid detection. Staying hidden matters most, especially where guest data flows through open networks.
