To identify potentially malicious extensions like FlexibleOrigin, users should watch for indicators such as missing developer contact information [2], infrequent updates [2], lack of a privacy policy [2], low user ratings [2], absence of a support site [2], and uncommon installation methods [2]. Suspicion should also be raised if an extension is promoted as free through paid ads, as this may indicate suspicious activity.

Organizations can protect themselves from these risks by carefully evaluating the necessity of extensions [2], assessing their popularity and security [2], and implementing mitigation techniques [2].
