How to Detect this Silent Threat



A new study conducted by Uptycs has uncovered a stark increase in the distribution of information stealing (a.k.a. infostealer or stealer) malware. Incidents have more than doubled in Q1 2023, indicating an alarming trend that threatens global organizations.

According to the new Uptycs’ whitepaper, Stealers are Organization Killers, a variety of new info stealers have emerged this year, preying on Windows, Linux, and macOS systems.

Telegram has notably been used extensively by these malware authors for command, control, and data exfiltration.


What is a Stealer?

A stealer is a type of malware that targets its victim by stealing sensitive information that can include passwords, login credentials, and other personal data. After collecting such data, the stealer sends it to the threat actor’s command and control (C2) system.

RedLine and Vidar, two well-known stealers, took advantage of log-providing services to infiltrate private systems. RedLine primarily targets credentials and cryptocurrency wallets on Windows systems, as well as browser information, FTP connections, game chat launchers, and OS data. Vidar relies on delivery methods such as phishing emails and cracked software for dissemination. Along with Racoon, it has been involved in a Google Ads malvertising operation that targets users looking for popular applications.

In one of the biggest attacks in 2022, Uber fell victim to an attack by a threat actor using the Racoon stealer. The attacker tricked victims into clicking on a fake two-factor authentication notification, compromising their systems. With access to Uber’s VPN, the attacker infiltrated the company’s internal network resources. They were able to escalate account privileges by exploiting the company’s access management service. As a result, they gained access to various Uber resources, including AWS, Duo, GSuite, OneLogin, Slack, VMware, and Windows.

The notorious Raccoon stealer malware has recently struck India, setting its sights on eight central government entities, including the Income Tax Department and central paramilitary forces. Through a malicious campaign, attackers successfully infiltrated computer systems, causing significant harm to these important institutions.
