First, I should consider the website itself. Otomi-games.com isn't one I recognize as a legitimate game website. Typically, official or reputable game sites have clear branding and are well-known within the industry. If this site isn't mainstream, that's a red flag. It might be a pirated game site or a phishing attempt.
I should check if Otomi-games.com is a known malicious site. Maybe run a quick search through security databases or reports. Also, look into the common practices of such sites. Often, pirated game sites bundle malware with downloads, like spyware, adware, or ransomware. The RAR might be a trojan in disguise, containing malicious software instead of the game itself.
Additionally, consider if the user might have encountered this link while browsing another site, possibly through a pop-up or a torrent site. That could mean the file is part of a larger distribution network for pirated content, which is illegal and risky. Emphasizing legal alternatives not only protects against malware but also supports the developers and companies that create the games.
