According to Uptycs security researcher Karthickkumar Kathiresan, the malware campaign is designed to acquire sensitive information like system details, cryptocurrency wallet information, browser histories, cookies, and login credentials of crypto wallets.
Details of the Campaign
- The multiple-stage infection sequence begins with an invoice-themed phishing email that comprises a link that downloads a password-protected ZIP archive file containing two files: A shortcut (.LNK) file and a batch (.BAT) file.
- Irrespective of what file has been deployed, the attack chain remains the same, fetching a batch script that installs an information-stealing payload from a GitHub repository. This is achieved by utilizing a legitimate PowerShell binary that as well is retrieved from GitHub.
- After being installed, the C#-based malware gathers system metadata and information from a variety of web browsers and cryptocurrency wallets, and then it transfers that data to a domain that is under the authority of an actor.
Info-stealers You Should Beware of
Vidar stealer: It resurfaced with certain sophisticated tactics in order to exploit popular social media platforms such as Telegram, Mastodon, TikTok, and Steam. Back in December 2022, numerous information stealers were discovered targeting the PyPI repository. It was discovered that 16 packages, each of which had been downloaded more than 100 times, were being used to distribute ten different stealer variants.
In today’s world of cybercrime, which is constantly evolving, one of the most severe forms of malware that one must beware of is the info-stealer. This covert digital burglar may sneak into your devices and networks to steal sensitive information, consequently rendering you vulnerable to identity theft, financial fraud, or more devastating repercussions.
In order to protect oneself from malware attacks like info-stealer, it is advised by Uptycs to update passwords regularly and employ robust security controls with multi-layered visibility and security solutions.
