This report details an investigation into a malware operator using GitHub repositories to stage malicious loaders and RAT payloads. The operator's infrastructure includes multiple RAT families such as AsyncRAT, DcRat, Remcos, and XWorm, along with phishing templates targeting Colombian government institutions. The delivery infrastructure spans GitHub, Bitbucket, AWS S3, and DuckDNS for command-and-control. Phishing campaigns use judicial notification and traffic violation lures with password-protected archives to target Colombian organizations. The investigation highlights how operational security failures can expose entire malware production workflows beyond individual samples.

A massive network of over 20,000 fraudulent e-commerce domains has been uncovered, all sharing common infrastructure and design patterns. These fake shops, primarily using the .shop domain, are designed to steal payment details and personal data from unsuspecting consumers. The operation is highly industrialized, with domains resolving to just 36 IP addresses, indicating a franchise-style model where a core team manages servers and templates while individual operators launch storefronts. The shops use familiar e-commerce tactics and psychological pressure to lure victims. To protect yourself, use browser protection tools, scrutinize unfamiliar domains, be wary of deep discounts, and look for independent reviews before making purchases.
