More about Nova Stealer

One of the primary features of Nova Stealer is its capability to extract passwords from compromised systems. This enables the stealer to capture login credentials for email accounts, social media platforms, or financial services. By gaining such access, threat actors can potentially compromise personal and confidential data, leading to financial losses and privacy breaches for victims.

Furthermore, Nova Stealer's ability to record screens adds another layer of threat to its malicious capabilities. Screen recordings can capture a wealth of sensitive information, including personal conversations, financial transactions, and browsing activities. Also, the malware can be injected into Discord, a popular communication platform.

By infiltrating Discord, Nova Stealer can intercept sensitive conversations, access shared files, and gather additional information on potential targets. This versatility enables threat actors to exploit a diverse range of channels for their malicious activities, further amplifying the impact of the malware. For instance, they may use the malware to trick users into opening malicious links.

Another concerning aspect of Nova Stealer is its ability to hijack cryptocurrency wallets. By gaining control over cryptocurrency wallets, Nova Stealer can siphon off digital assets, leading to substantial financial losses for victims. The decentralized and pseudonymous nature of cryptocurrencies makes it challenging to trace and recover stolen funds.

How did Nova Stealer infiltrate my computer?

Nova Stealer is distributed through cunning malvertising campaigns on Facebook, where cybercriminals exploit sponsored ads to impersonate reputable AI software providers and lure users into downloading malicious payloads. These campaigns, targeting users across Europe, employ convincing descriptions and AI-generated content to enhance legitimacy.

Once users click on the ads, they are directed to malicious web pages that automatically download Nova Stealer and other intrusive stealers onto their systems. In addition to malvertising campaigns, malware is distributed through phishing emails (malicious links or files in emails), malicious websites, infected USB drives, and peer-to-peer networks.

Pirated software, cracking tools, key generators, and vulnerabilities in outdated software are also used to distribute malware.

How to avoid installation of malware?

Users should exercise caution when browsing the internet and downloading files and programs. They should only visit trusted websites, refrain from clicking on suspicious links and ads or opening shady email attachments, and download software from reputable sources. Implementing robust security software, such as antivirus and antimalware programs, is also important.

Regularly updating operating systems, software, and security tools is also essential to patch known vulnerabilities and stay protected against emerging threats. If you believe that your computer is already infected, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.
