Beware of Fake Browser Updates! Hackers Deploy NetSupport RAT & StealC Malware

A new cyberattack campaign is tricking users into downloading malware through fake browser update alerts. Hackers from the SmartApeSG group are targeting compromised websites to distribute NetSupport RAT and StealC malware, which can steal sensitive data and give attackers remote access to your system.

This sophisticated attack uses social engineering and advanced evasion techniques, making it difficult to detect. Users are urged to stay alert and avoid downloading browser updates from unknown sources.

Key Threats You Should Know

  • Fake Browser Updates – Hackers inject malicious scripts into compromised websites, displaying pop-ups urging users to update their browsers (Chrome, Edge, Firefox).

  • NetSupport RAT Installation – When users click the fake update, a remote access trojan (RAT) is installed, allowing hackers to monitor keystrokes, steal files, and control the infected system.

  • StealC Malware Attack – NetSupport RAT later downloads StealC malware, which steals saved passwords, cryptocurrency wallets, and browser session cookies.

  • Advanced Hacking Techniques – Attackers use DLL side-loading and fileless malware to bypass security software and remain undetected.
  • Widespread Threat – Similar fake update scams have been linked to major ransomware attacks in the past.

How to Stay Safe

✔ Never download browser updates manually. Browsers update automatically—don’t trust pop-ups asking you to install updates.

✔ Avoid suspicious websites. If a site looks outdated or unfamiliar, close it immediately.

✔ Enable strong security software. Use Net Protector Total Security to detect and block malware before it infects your system.

✔ Restrict PowerShell execution. This can prevent hidden scripts from running malware in the background.

✔ Monitor network activity. Look for unusual processes running in the background or unauthorized remote connections.

✔ Stay informed. Regularly update your knowledge about the latest cyber threats and scams.

This fake browser update scam is a major cybersecurity threat, using remote access trojans (RATs) and data-stealing malware to infiltrate systems. By staying alert and using strong security measures, you can protect yourself from falling victim to these cybercriminals.
