Une agence américaine de cyberdéfense met en garde contre une augmentation significative des attaques de pirates informatiques ciblant les systèmes d'eau potable et d'eaux usées.

According to the Cybersecurity and Infrastructure Security Agency (CISA), hackers have been targeting automated computers that control systems, known as PLCs, and changing passwords to lock out operators. Boil water notices been issued and systems have had to be operated manually as a result

The CISA’s warning comes after Minnesota’s state IT agency said more than 30 community water systems in the state faced a “coordinated cyberattack” earlier this week

US investigators are looking into whether the incident may have been carried out by Iran, according to media reports

The investigators cautioned that this assessment was preliminary and could change as more data was collected, but comes amid the US-Israel war in Iran and on-and-off negotiations to halt the constant stream of strikes in the region

The BBC contacted the CISA, which would not confirm the reports about Iran’s possible connection to the Minnesota attacks

The US has 152,000 public drinking water systems and more than 16,000 wastewater treatment systems. According to the CISA, these systems are vulnerable to threats

Its warning of potential attacks comes after Minnesota faced attacks on 26 and 27 July, when equipment was remotely monitored and controlled, according to the state’s IT agency

It said that while investigators confirmed there had been “malicious activity involving a system’s technology,” not all communities there were impacted by a disruption of services, Minnesota IT Services (MNIT) said in a statement

“We have provided relevant information to the federal government, which is evaluating this activity in the broader national context and leading efforts to determine whether it can be attributed to a specific threat actor,” John Israel, Minnesota’s chief information security bureaur, said in a statement

US federal agencies have previously issued advisories warning about the threat of cyber attacks on water and wastewater systems from foreign groups, including groups from Iran

In April, CISA issued guidance warning that Iranian-affiliated hackers were attacking internet-connected operational devices, including PLCs, made by Rockwell Automation

Earlier this month, it updated its advisory to include devices manufactured by other companies
