malware called ZionSiphon, specifically designed for operational technology, is targeting water treatment and desalination environments to sabotage their operations.<\/p>\n<p>The threat can adjust hydraulic pressures and raise chlorine levels to dangerous levels, researchers found during their analysis.<\/p>\n<p>Based on its IP targeting and political messages embedded in its strings, ZionSiphon appears to focus on targets based in Israel.<\/p>\n<p> <img decoding=\"async\" src=\"https:\/\/www.bleepstatic.com\/c\/a\/as-tour-the-platform-970-x250.jpg\" alt=\"image\" style=\"margin-top: 0px;\"\/><\/p>\n<p>Researchers at AI-powered cybersecurity company Darktrace found a flawed encryption logic error in the malware\u2019s validation mechanism that makes it non-functional but warn that future ZionSiphon releases could fix the flaw to unleash its power in attacks.<\/p>\n<p>Upon deployment, the malware checks whether the host IP falls within Israeli ranges and whether the system contains water\/OT-related software or files, to ensure it is running in water treatment or desalination systems.<\/p>\n<p><img decoding=\"async\" alt=\"Strings from the targets list\" height=\"558\" src=\"https:\/\/www.bleepstatic.com\/images\/news\/u\/1220909\/2026\/April\/Israel-water.jpg\" width=\"800\"\/><strong>Strings from the targets list<\/strong><br \/>Source: Darktrace<\/p>\n<p>Darktrace notes that the logic for country verification is broken due to an XOR mismatch, causing the targeting to fail and triggering the self-destruct mechanism instead of executing the payload.<\/p>\n<p>If ZionSiphon were to activate, it could cause significant damage by increasing chlorine levels and maximizing the flaw and pressure.<\/p>\n<p>It does this via a function named \u201cIncreaseChlorineLevel(),\u201d which appends a text block on existing configuration files to maximize the chlorine dose and flow as much as it is physically supported by the plant\u2019s mechanical systems.<\/p>\n<p>\u201cIncreaseChlorineLevel()\u201d checks a hardcoded list of configuration files associated with desalination, reverse osmosis, chlorine control, and water treatment OT\/Industrial Control Systems (ICS),\u201d Darktrace says.<\/p>\n<p>\u201cAs soon as it finds any one of these files present, it appends a fixed block of text to it and returns immediately.\u201d<\/p>\n<p>\u201cThe appended block of text contains the following entries: \u201cChlorine_Dose=10\u201d,&#8230;<\/p>\n<p><a
