A joint advisory from the FBI, CISA, the NSA, the Secret Service, and South Korean police warns that the Gunra ransomware group is exploiting known Fortinet VPN vulnerabilities to bypass multi-factor authentication and break into networks, targeting government agencies and critical infrastructure. Gunra, believed to be built on leaked Conti source code, runs a double-extortion model: it steals data before encrypting, using a custom tool to pull files from Microsoft OneDrive and SharePoint and moving large archives to a file-sharing service with utilities like RClone and 7-Zip. The final payload appends a distinct extension and drops a ransom note. The group has grown into a ransomware-as-a-service operation recruiting access brokers.
CISA, the FBI, NSA, EPA, and Department of Energy updated a joint advisory warning that Iran-affiliated actors are exploiting internet-facing operational technology across US critical infrastructure, and in some cases disrupting it. Since at least March 2026 the group has targeted programmable logic controllers, the small industrial computers that run automation processes, extracting device project files and then modifying or deleting the control logic. Water, wastewater, energy, and government facilities are among the affected sectors, and some victims experienced operational disruption and financial loss. The July update broadened the range of affected device makers, added detection guidance, and refreshed the published indicators of compromise.
The Iran-linked group Handala claims it breached California Water Service (Cal Water), one of the largest US investor-owned water utilities, and published a 5GB sample to prove it. Analysts say the attackers reached a customer billing database holding personal data (names, addresses, account and payment details) and an internal GPS-correction server, leaking administrative credentials in the process. Handala framed the attack as retaliation for US actions against Iran and boasted it could disrupt water supply, but researchers stress the evidence does not support that claim, neither system controls water treatment, and the group is known to exaggerate. Cal Water has not yet publicly confirmed the incident.
Mackay Sugar, Australia's second-largest sugar producer, has shut down two of its Queensland mills after a cybersecurity incident, halting production and stopping sugarcane harvesting at the peak of the season. The company confirmed the attack on Wednesday and has brought in outside cybersecurity experts and local authorities to investigate and restore systems. It has not yet said who was responsible or whether data was stolen, but the operational shutdown is consistent with a ransomware attack. The incident is the latest example of attackers disrupting food and agriculture operations, a sector whose industrial systems are increasingly targeted for maximum pressure.
Israeli firm Gambit Security has forensically linked the late-March attack on the Los Angeles County Metropolitan Transportation Authority to Iran's Ministry of Intelligence and Security (MOIS), despite the attackers branding themselves as the pro-Iran hacktivist collective 'Ababil of Minab.' The group posted videos claiming it wiped hundreds of terabytes and stole over a terabyte of files. LA Metro confirmed the breach on April 2, 2026, and had to check hundreds of servers for compromise before bringing them back online. The case illustrates a recurring pattern of state operations wearing a hacktivist costume to provide deniability while targeting critical infrastructure.
Recorded Future News has connected last summer's three-hour POST Luxembourg outage - which took down landline, 4G, and 5G networks across the country and left residents unable to dial emergency services - to a zero-day in Huawei enterprise routers running VRP. Specially crafted network traffic merely passing through caused the routers to enter a continuous restart loop. Luxembourg's prosecutor concluded no one had targeted Luxembourg specifically; the data was just transit traffic. Huawei has not assigned a CVE for the bug and routes its enterprise advisories through a restricted customer portal rather than publicly, leaving operators with little ability to track exposure.
US officials believe Iranian-affiliated actors broke into internet-exposed automatic tank gauge (ATG) systems at gas stations across multiple states, then changed the displayed fuel levels without altering the actual amounts. The intrusions caused no shortages, but falsified ATG readings could theoretically hide a real fuel leak. ATGs have been a known soft target for over a decade. The activity tracks with a broader Iranian push during the war that began in late February: disruptions at US oil, gas, and water sites, shipping delays at Stryker, and the leak of FBI Director Kash Patel's emails. Attribution is preliminary because intruders left almost no forensic evidence.
Polish intelligence service ABW announced Wednesday that hackers attacked the industrial control systems at multiple Polish water treatment plants. The Record reports the targeting profile is consistent with state-aligned activity - patient reconnaissance, careful access, no data destruction. Polish authorities have not formally attributed the attack but the timing (alongside Russia-Ukraine conflict and Russia's interest in Polish infrastructure as a NATO frontline state) is unmistakable. Similar incidents have been reported in Germany, Austria, and the Netherlands over the past 12 months. No service disruption was reported, but the access establishes pre-positioning.
La Repubblica reported a significant breach at Sistemi Informativi, a wholly-owned IBM Italy subsidiary that manages IT infrastructure for Italian public agencies and key industries. Multiple intelligence sources attribute the attack to Salt Typhoon, the China-linked espionage group that has hit US telecoms (AT&T, Verizon, Viasat), Canadian telecom firms, the US Army National Guard, Dutch government networks, and now Italian critical infrastructure. Salt Typhoon's hallmark is patience - prolonged data exfiltration, silent network observation, and infrastructure compromise rather than fast theft. The group has been active since at least 2019 and has reportedly hit 200+ companies across 80 countries.
Kaspersky disclosed a previously undocumented cyber-espionage group called HeartlessSoul that has been targeting Russian government agencies and aviation companies since at least September 2025 to steal geographic information system (GIS) data - the specialized files containing detailed maps of roads, engineering networks, terrain, and strategic facilities. The targeting suggests state-aligned interest in Russian infrastructure mapping rather than financial gain. Kaspersky did not name a likely sponsor but the targeting profile is consistent with a Ukraine-aligned or Western-aligned operator. The group uses tailored phishing, custom malware, and persistent network access.
