💻 APT37 hides the RoKRAT spyware in JPEG images:

• The North Korean group APT37 uses steganography to conceal RoKRAT within ordinary JPEG photographs, which it spreads through bait on topics of national security and North Korean defectors.

• The virus steals system information, documents, and screenshots with the aim of long-term espionage against South Korean government structures and analytical centers.

ℹ️ Mechanism of operation: when the infected file is opened, a two-step XOR encryption is activated, which extracts the hidden code from the image and injects it into system processes (mspaint.exe, notepad.exe), after which it transmits the stolen data through legitimate cloud APIs Dropbox, Yandex, and pCloud.

👥 Attackers can embed password and private key stealers into ordinary memes or NFT images, which are then distributed through crypto communities on Discord, Telegram, and Twitter. When such a file is opened, the virus stealthily steals seed phrases, wallet passwords, and exchange login data.
