- Malice lurks in pixels, cloaked in JPEGs—how quaint!
- Clouds, once havens of dreams, now host secret war rooms. 😬
- Crypto fortunes vanish like smoke—APT37’s tea party. ☕💣
Behold, the latest ploy of North Korea’s APT37 gang: a malware named RoKRAT, a digital slyboots that hides in plain sight. It embeds its venom in image files, a masterclass in steganography, rendering it invisible to the feeble eyes of traditional antivirus. One might call it the Houdini of cybercrime, escaping detection by masquerading as a harmless photograph.

RoKRAT, with its fileless antics, injects its code into innocent Windows programs like mspaint.exe and notepad.exe. It dances in memory, avoiding the clutches of antivirus software like a ghost in the machine. One might say it’s the digital equivalent of a thief who never touches the ground.
Cloud storage services—Dropbox, Yandex, pCloud—have been co-opted as command-and-control centers. APT37 uses these platforms as if they were their own private taverns, sipping data and issuing orders. How very modern, to weaponize the very tools we trust for storing our holiday photos!
The Deceptive Veil of Harmless Pictures

RoKRAT’s payload is tucked into JPEGs, a double-layer XOR encryption cloaking its intentions. It decrypts and executes in memory, a digital magician pulling a rabbit from a hat made of ones and zeros. The malicious LNK files, zipped like presents, unleash PowerShell commands to fetch these “innocent” images from cloud accounts under the attackers’ control. A masterstroke of deception!
Cloud Storage: The New Bastion of Digital Tyrants
APT37 wields cloud APIs like a conductor of a digital orchestra, directing traffic to api.pcloud.com, cloud-api.yandex.net, and api.dropboxapi.com. The malware’s traffic blends seamlessly with legitimate operations, a wolf in sheep’s cloud storage. Revoked tokens and masked emails ensure the attackers linger unnoticed, like uninvited guests at a party who’ve forgotten to RSVP.
This persistence is a testament to their cunning. Who would suspect their precious Dropbox folder of harboring a digital villain? The defenders, it seems, are outwitted by their own tools.

APT37’s Money Grab
The crypto sector, with its digital gold, is now a target. RoKRAT steals wallet keys and credentials, while secretly mining cryptocurrencies. APT37’s spear-phishing campaigns are their invitations to the victims’ systems, extracting data like a digital vampire. The cloud infrastructure of exchanges and wallets becomes a treasure trove, drained unnoticed. One might say it’s the cyber equivalent of a heist in a bank vault—except the vault is a server, and the guards are asleep.
