A new information malware pressure named Statc Stealer has been uncovered infecting equipment running Microsoft Windows to siphon sensitive particular and payment information and facts.
“Statc Stealer reveals a broad variety of stealing abilities, building it a substantial menace,” Zscaler ThreatLabz researchers Shivam Sharma and Amandeep Kumar reported in a technical report posted this 7 days.
“It can steal delicate information from a variety of web browsers, like login data, cookies, web data, and tastes. Moreover, it targets cryptocurrency wallets, qualifications, passwords, and even info from messaging applications like Telegram.”
Penned in C++, the destructive stealer finds its way into sufferer units when probable victims are tricked into clicking on seemingly innocuous adverts, with the stealer imitating an MP4 video file structure on web browsers like Google Chrome.
The initial-stage payload, even though dropping and executing a decoy PDF installer, also stealthily deploys a downloader binary that proceeds to retrieve the stealer malware from a distant server via a PowerShell script.
The stealer options sophisticated checks to inhibit sandbox detection and reverse engineering evaluation, and establishes connections with a command-and-management (C&C) server to exfiltrate the harvested data using HTTPS.
One particular of the anti-assessment features a comparison of the file names to inspect for any discrepancies and halt its execution, if identified. Qualified web browsers include Google Chrome, Microsoft Edge, Mozilla Firefox, Courageous, Opera, and Yandex Browser.
“The significance of Statc Stealer’s exfiltration procedure lies in its potential to steal delicate browser knowledge and send it securely to its C&C server,” the researchers claimed. “This will allow the malware to harvest precious facts, these as login qualifications and own aspects, for malicious purposes like id theft and economical fraud.”
The findings arrive as eSentire released an investigation of an current version of Raccoon Stealer, which had its variation 2.1 introduced previously this February.
The authors of Raccoon Stealer quickly halted get the job done on the malware very last yr adhering to the arrest of Mark Sokolovsky in March 2022, who was uncovered as a person of the main builders just after he created the lethal miscalculation of linking a Gmail account he applied to indicator up for a cybercrime discussion board less than the alias Photix to an Apple iCloud account, consequently revealing his genuine-globe id.
“The up-to-date edition involves functions this sort of as Sign Messenger knowledge selection, cleaning from Defender detection (likely altering the code, obfuscation to steer clear of detections), and auto brute-forcing for crypto wallets,” eSentire pointed out previous 7 days.
