Then, as there is no longer an incentive to keep the vulnerability a secret, it suddenly becomes attractive to exploit against anybody who hasn’t updated their device. As soon as a vulnerability is reported to the vendor or becomes publicly known, it will be fixed. When useful vulnerabilities are discovered, they are often used against high-value targets first.
