hacking efforts against have hadÌýmixed results, based on recently released reports.

US-based outfit FireEye published research into crude offensivesÌýagainst industry and infrastructure systems in Israel on Tuesday.

It said groups with apparent "political" aims are often carrying out these types of digital activities.

FireEye identified cases where hackers' remarks show they either failed to fully comprehend the systems they attempted to infiltrateÌýor wanted to generate infamy.

One band of hackers said they had performedÌýan attack in Israel, hitting back over aÌýgas explosion near a in June 2020.

Figures withinÌýboth Israel and the United States' intelligence apparatusÌýdenied involvement at the time, according to The New York Times.

The hackers said they had infiltrated a "gas system" in Israel, which FireEye revealedÌýwas, in reality, controlling ventilation at a restaurant kitchenÌýin the city of Ramat Hasharon, whichÌýneighboursÌýTel Aviv.

Collectives employing "anti-Israel/pro-Palestine rhetoric" online do appear to have infiltrated systems such as a "solar energy asset", though there was no mention of country of origin.

It is also unclear what the significance of these systems were.

The FireEye report came on the same day as another about a "threat group" named Agrius, released by SentinelOne, an Israeli digital security company.

SentinelOne said Agrius have been active in Israel since 2020.

The company said this began with spying activities, before Agrius moved to "wiper attacks".

"Wipers" are software destroys or "wipes" the files and other data on a victim's system.

SentinelOne said it has "medium confidence" that Agrius is "of Iranian origin" due to factors including its use of this approach, which it claims is commonly used by Iranian groups.

Agrius reportedly uses a wiper called "Apostle", which it is believed to have developed itself.

This was not properly developedÌýat first and so did not work.

This caused the hackers to turn to DEADWOOD in its Israel offensive, another wiper that is suspected of ties to an Iranian group.

However, they have since fixed the problemÌýand made Apostle work as ransomware, allowing it to hold files hostage.

SentinelOne argued, based on evidence, that this is being used "for its disruptive capabilities".

The organisation said a UAE "nation-owned critical infrastructure facility" was attacked with it.

The cyber efforts against Israel come amid what has been described as a between it and Iran.

Last July, the underground nuclear facility of , with Tehran claiming Israel was behind this.
