	"plain_text": "Australian Electricity Provider ‘CS Energy’ Hit by Ransomware\r\nBy Eduard Kovacs\r\nPublished: 2021-12-09 · Archived: 2026-04-05 15:30:38 UTC\r\nAustralian electricity provider CS Energy has been hit by a ransomware attack, but the company says\r\nelectricity generation has not been affected and it has denied claims that the attack was conducted by a\r\nstate-sponsored threat group.\r\nThe attack was discovered on November 27 and the company informed the public about the incident a few days\r\nlater.\r\nQueensland-based CS Energy, which is owned by the local government, provides electricity to millions of homes,\r\nas well as to large commercial and industrial customers in Queensland.\r\nCS Energy said the ransomware compromised devices on its corporate network, which was quickly isolated from\r\nother internal networks to prevent the malware from spreading. Safety and operations at its Kogan Creek and\r\nCallide power stations were not impacted, nor was power generation and delivery.\r\nThe company is working on restoring affected systems and noted that “Australia’s National Electricity Market is\r\ndesigned to ensure there is enough power generation and network capacity to securely meet customer demand,\r\neven in the event of unexpected outages of transmission lines and generators.”\r\nSome local news publications claimed — citing sources — that the attack on the energy firm has been linked to\r\nChinese state-sponsored hackers. In response, CS Energy issued a statement on Wednesday to clarify that there\r\nwas no indication of the attack being “state-based.”\r\nAdvertisement. Scroll to continue reading.\r\nIn fact, it appears that the attack involved the well-known Conti ransomware, whose operators not only encrypt\r\nfiles on compromised systems, but also steal valuable data in an effort to convince the victim to pay a ransom.\r\nhttps://www.securityweek.com/australian-electricity-provider-cs-energy-hit-ransomware\r\nPage 1 of 2\n\nConti operators run a website where they leak the data of victims that refuse to pay up. CS Energy has been listed\r\non that site since November 27, but the cybercriminals have yet to make public any files associated with the\r\nenergy company.\r\nCS Energy is not the only electric utility hit by ransomware in recent days. The Delta-Montrose Electric\r\nAssociation (DMEA), a rural electric cooperative that serves more than 34,000 customers in Colorado, suffered\r\nsignificant disruption and damage as a result of a ransomware attack last month, but its power grid was not\r\nimpacted.\r\nDMEA admitted that the attack resulted in disruption to email, phone and billing systems, as well as the loss of\r\nhistorical data dating back more than 20 years.\r\nRelated: Rural Alabama Electric Cooperative Hit by Ransomware Attack\r\nRelated: More Threat Groups Target Electric Utilities in North America\r\nRelated: Massachusetts Electric Utility Hit by Ransomware\r\nSource: https://www.securityweek.com/australian-electricity-provider-cs-energy-hit-ransomware\r\nhttps://www.securityweek.com/australian-electricity-provider-cs-energy-hit-ransomware\r\nPage 2 of 2",
