Imagine if every time you were sick, all your doctor did was tell you to take some medicine.
And that's essentially what the industrial control vulnerability advisories have been like over the last year, according to a new report by Dragos.
Past attacks have shown that attackers can get access to power grids and factories, with Russian hackers causing a blackout in Ukraine in 2016.
During 2017, Dragos looked at 163 vulnerability advisories, most of which offered no real solutions.
More than 60 percent of vulnerability warnings said critical infrastructure could get hijacked, while 71 percent of reported vulnerabilities in 2017 could disrupt a person's ability to monitor systems, according to the report.
In these warnings, up to 72 percent of the advisories told IT teams only to patch their systems.
