Lately, there have been a number of high-profile cyber-attacks on water methods within the US, together with an incident in 2021 in Oldsmar, Florida, the place hackers tried to poison the water provide by altering chemical ranges.
Such assaults have raised alarms concerning the potential for cybercriminals and nation-state actors to focus on important public providers.
Underfunded Water Utilities Face Rising Cyber-Threats
The American Water breach has now as soon as once more drawn consideration to the water sector’s broader challenges, which regularly lacks adequate cybersecurity funding.
Tim Erlin, a safety strategist at Wallarm, famous that water utilities are more and more reliant on trendy digital applied sciences, comparable to APIs and internet functions, which may introduce new vulnerabilities.
“Water and wastewater therapy services are sometimes underfunded in the case of cybersecurity, however they face the identical threats as different organizations,” Erlin warned. “CISA […] has centered on the water and wastewater therapy sector, however these adjustments take time and finances.”
