The title of this diary is perhaps a bit catchy but the question is important. I don't consider myself as a good developer. That's not my day job and I'm writing code to improve my daily tasks. I like to say “I'm writing sh*ty code! It works for me, no warranty that it will for for you”. Today, most of my code (the skeleton of the program) is generated by AI, probably like most of you.
A comprehensive analysis of a Potentially Unwanted Application (PUA) identified as HEURRemoteAdmin.GoToResolve.gen reveals its association with the GoTo Resolve Unattended Access application. While digitally signed by GoTo Technologies USA, LLC, the sample exhibits behaviors typical of PUAs, including silent installation, background thread execution, and persistent presence on the system. The application's use of the Restart Manager library, often seen in ransomware and wiper malware, raises concerns. Although no direct malicious payload was observed, the remote access capabilities present a significant security risk, potentially allowing unauthorized system control or deployment of secondary malware. The sample's detection by UltraAV further supports its classification as a security threat, warranting removal unless explicitly authorized and managed within organizational security policies.
