ZecOps says the victims included members of a Fortune 500 company in North America, a Japanese telecom executive, a journalist in Europe, and what the researchers call a 'VIP' in Germany, among other victims. But the researchers also note they found indications that the bugs were actually exploited in devices of their clients. 'These bugs alone cannot cause harm to iOS users – since the attackers would require an additional infoleak bug & a kernel bug afterwards for full control over the targeted device,' it says. The ZecOps research suggests a different story, though: Perhaps attackers are willing to settle in some cases for using less reliable, but cheaper and more abundant zero-click tools. Zero-click exploits are often thought of as highly reliable and sophisticated tools that are only developed and used by the most well-funded hackers, particularly nation state groups.

They’re also valuable, because less interaction means fewer traces of any malicious activity. Vulnerabilities that can be exploited for zero-click attacks are rare and are prized by attackers because they don't require tricking targets into taking any action-an extra step that adds uncertainty in any hacking scheme.

Research published this week by the threat monitoring firm ZecOps shows the types of vulnerabilities hackers can exploit to launch attacks that don’t require any interaction from the victim at all-and the ways such hacking tools may be proliferating undetected. But not all attacks require a user slip-up to open the door. Institutions and regular web users are always on alert about avoiding errant clicks and downloads online that could lead their devices to be infected with malware.
