Overview

Tnega is highly adaptive malware targeting Windows computers, usually spread through phishing emails, malicious websites, and software cracks. Its primary goal is to infiltrate systems and deploy additional malware.

Once active, Tnega alters system settings, tweaks the registry, and turns off security features to stay undetected. It steals sensitive data, which hackers use for financial gain, identity theft, dark web sales, and ransom demands. In addition, Tnega disguises itself as legitimate software, making it hard to detect with standard cybersecurity tools.

Possible symptoms

Possible symptoms of the Tnega trojan include:

  • Unexpectedly slow system performance or random crashes.
  • Unusual spikes in network activity.
  • Unfamiliar outbound connections.
  • Unknown processes or applications running in the background.
  • Disabled security software (antivirus or firewall).
  • Random pop-ups or error messages.
  • Diminished storage space.

Sources of the infection

Tnega usually sneaks into systems through modified versions of games, cheats, and game extensions. Other sources of infection include:

  • Phishing emails with malicious attachments and URLs. Unsuspecting users click on them and unknowingly download Tnega onto their computers.
  • Downloads from untrusted or malicious websites.
  • Infected removable media, including USB drives, external hard drives, and memory cards.
  • Unpatched system vulnerabilities.
  • Social engineering techniques that hackers use to trick users into executing harmful files.

Protection

Like any trojan, Tnega's consequences can be devastating for businesses and individuals, causing system damage, data theft, and financial losses. Let’s look at how you can protect your computer from Tnega:

  • Update your software. Keep your software, apps, and operating system up to date to protect against known vulnerabilities. Whenever you get a notification about a new version, make sure to update it right away.
  • Be cautious about your downloads. Never download software from untrusted sources or pirated websites. Also, be cautious about email attachments and never download files from unfamiliar addresses.
  • Control user privilege. If you run an extensive computer network, only give people access to what they really need. Avoid handing out admin rights unless it’s absolutely necessary. This way, even if Tnega sneaks in, it won’t do much damage.
  • Use Threat Protection Pro™. Get NordVPN with the Threat Protection Pro™ cybersecurity tool, which alerts you to dangerous websites, blocks malicious ads, and scans your downloads for malware, including threats like Tnega.
  • Educate yourself about cyber threats. Knowing how hackers infect devices can protect you from Tnega and other threats. Educate yourself about the most popular scams, malware, and social engineering attacks.

Tnega removal

If you’ve spotted one of those Tnega variants on your computer, disconnect from the internet right away to stop it from downloading more malware. Next, restart your computer in safe mode to prevent the malware from running. Run a full system scan with up-to-date antivirus software and remove the trojan.

If you’re tech-savvy, you can inspect your system and manually delete any leftover malicious files or programs linked to Tnega. If the infection is severe, consider restoring your system from a clean backup.
