What avast-premium-security-detection does

The skill examines repositories posing as Avast Premium Security distributions. It looks for piracy language, fake activation claims, unusual repository metadata, weak project documentation, and signs that a supposed software package may be a malware dropper.

Its examples cover several checks: scanning executable content for terms such as keygen, loader, and activator; assigning risk from repository metadata; comparing a file with an official SHA-256 value; and checking whether a download URL uses an official domain. The snippets are in C++. The checksum example uses OpenSSL and curl, while the behavior-monitoring section starts with Windows process APIs.

The checksum path depends on OpenSSL, and the behavior-monitoring example is tied to Windows APIs.

What it helps with

  • review a repository offering a cracked antivirus
  • spot keygen and loader indicators in an executable
  • score repository risk from metadata and description
  • compare a download with an official SHA-256
  • check whether a download source uses an official domain

Example prompts for the agent

  • Analyze this Avast repository for signs of a malware distribution scheme.
  • Check whether this security software repository looks like a piracy scam.
  • Scan the file for keygen, loader, activator, PowerShell, and webhook indicators.
