Cybersecurity researchers are warning of two distinctive data-stealing malware, named FFDroider and Lightning Stealer, that are able of siphoning facts and launching even more assaults.
“Made to send out stolen credentials and cookies to a Command & Command server, FFDroider disguises alone on victim’s equipment to seem like the immediate messaging application ‘Telegram,'” Zscaler ThreatLabz scientists Avinash Kumar and Niraj Shivtarkar claimed in a report posted last week.
Data stealers, as the title implies, are equipped to harvest sensitive facts from compromised equipment, these types of as keystrokes, screenshots, documents, saved passwords and cookies from web browsers, that are then transmitted to a distant attacker-managed area.

“The stealer symptoms into victims’ social media platforms using stolen cookies, and extracts account details like Facebook Advertisements-manager to operate malicious commercials with saved payment solutions and Instagram through API to steal individual facts,” the researchers reported.
FFDroider also will come with a downloader features to upgrade alone with new modules from an update server that permits it extend its function established above time, enabling destructive actors to abuse the stolen data as a vector for original accessibility to a target.
Major Function of Lightning Stealer
Lightning stealer operates in a comparable vogue in that it can steal Discord tokens, knowledge from cryptocurrency wallets, and details pertaining to cookies, passwords, credit rating cards, and search heritage from far more than 30 Firefox and Chromium-centered browsers, all of which is exfiltrated to a server in JSON structure.
“Details Stealers are adopting new techniques to grow to be much more evasive,” Cyble scientists stated, including it “witnessed ransomware teams leveraging Facts Stealers to attain first network access and, ultimately, exfiltrating delicate knowledge.”
The advancement arrives as stealer malware is getting an significantly frequent incidence across unique attack campaigns in current months, in component to fill the void left by Raccoon Stealer’s exit from the current market in late March owing to the ongoing war in Ukraine.
In February 2022, Cyble Investigate disclosed specifics of an emerging risk termed Jester Stealer that’s engineered to steal and transmit login credentials, cookies, credit card info together with data from passwords supervisors, chat messengers, email clientele, crypto wallets, and gaming apps to the attackers.
Considering that then, at minimum three different info-stealers have emerged in the wild, which include BlackGuard, Mars Stealer, and META, the very last of which has been observed shipped by means of malspam strategies to gather delicate knowledge.
