Cybersecurity researchers are warning of two different information-stealing malware, named FFDroider and Lightning Stealer, that is capable of siphoning data and launching further attacks.
“Designed to send stolen credentials and cookies to a Command & Control server, FFDroider disguises itself on victim’s machines to look like the instant messaging application ‘Telegram,'” Zscaler ThreatLabz researchers Avinash Kumar and Niraj Shivtarkar said in a report published last week.
Information stealers, as the name implies, are equipped to harvest sensitive information from compromised machines, such as keystrokes, screenshots, files, saved passwords, and cookies from web browsers, that are then transmitted to a remote attacker-controlled domain.
FFDroider is distributed through cracked versions of installers and freeware with the primary objective of stealing cookies and credentials associated with popular social media and e-commerce platforms and using the plundered data to login into the accounts and capture other personal account-related information.
Web browsers targeted by the malware include Google Chrome, Mozilla Firefox, Internet Explorer, and Microsoft Edge. The websites targeted encompass Facebook, Instagram, Twitter, Amazon, eBay, and Etsy.
“The stealer signs into victims’ social media platforms using stolen cookies, and extracts account information like Facebook Ads-manager to run malicious advertisements with stored payment methods and Instagram via API to steal personal information,” the researchers said.
FFDroider also comes with a downloader functionality to upgrade itself with new modules from an update server that allows it to expand its feature set over time, enabling malicious actors to abuse the stolen data as a vector for initial access to a target.
Lightning stealer operates in a similar fashion in that it can steal Discord tokens, data from cryptocurrency wallets, and details pertaining to cookies, passwords, credit cards, and search history from more than 30 Firefox and Chromium-based browsers, Read more:https://bit.ly/3vdI8X0
