Hot Take:

Once upon a time, USBs were the knights in shining armor, carrying our precious data across the digital realms. Now, they’ve turned to the dark side, with malicious LNK shortcuts as their weapons, and GitHub, Vimeo, and Ars Technica as their unsuspecting steeds. UNC4990, the newest band of cyber outlaws, has taken “hide and seek” to a whole new level, playing the game in broad daylight on platforms we trust. And get this—they’re making bank while we’re left scratching our heads. It’s a modern-day cyber heist, and your computer might just be the next stop for their malware merry-go-round.

Key Points:

  • USB drives are the Trojan horses of our time, tricking victims into launching malicious shortcuts.
  • Payloads are playing peekaboo on reputable sites like GitHub and Vimeo, where they’re harder to spot.
  • UNC4990’s trickery doesn’t compromise the hosting sites but does compromise your computer.
  • EMPTYSPACE and QUIETBOARD are not sci-fi movie titles but malware names you should be wary of.
  • These cybercriminals are not just coding for fun—they’ve raked in over $55,000 in crypto-coins!

It's showtime, and the curtain rises on a USB device—our unsuspecting protagonist. But wait, it's a trap! The plot thickens with a click on a seemingly innocent shortcut, and bam! You've been cast in a hacker's power play. The shortcut's a script that calls in reinforcements from GitHub, Vimeo, and even a tech forum, fetching the URL to our villain, EMPTYSPACE. The sites? Just minding their own business, while their features are hijacked to host encoded payloads. No vulnerabilities exploited, just the good old 'hide in plain sight' tactic. But like all great heists, once the act's busted, the evidence vanishes, with Mandiant sweeping up the digital breadcrumbs from these platforms.


With a flick of a script, the PowerShell wizardry decodes and summons the intermediary payload from its online hiding spot. Like a digital Frankenstein, EMPTYSPACE comes alive on your computer, ready to open the gates for QUIETBOARD. This isn't your friendly neighborhood backdoor; it's a Swiss Army knife of cyber mischief, jacking cryptocurrencies, spreading like the flu via USB, and peeking over your virtual shoulder with screenshots. And just when you think it's over, QUIETBOARD digs its claws in, ensuring it'll wake up with your computer every time. UNC4990's lab rats are tirelessly tweaking this cyber concoction, proving that even old-school USB tricks are still part of the cybercrime zeitgeist. So next time you plug in a USB, think twice—it might just be the chariot for a digital plunder.


While the story unfolds like a cybercrime soap opera, the moral is clear: the digital world is full of masquerades, and even the most benign platforms can harbor sinister secrets. Our anti-heroes, the USB devices, serve as a stark reminder that what lies beneath a simple double-click can be a nefarious network of malware. And as for UNC4990, their digital alchemy turns code into coin, proving that cybercrime can indeed pay—unfortunately, at our expense. So, laugh in the face of danger if you will, but maybe keep your USBs in lockdown, lest they join the dark carnival of cyber bandits.
