Japan's GMO Internet Group is  offering up to $1 million in total  for tips that help catch the attackers who breached its Onamae.com Desktop Cloud service, after refusing to pay an extortion demand. The reward program opened on October 28 and pays only if a tip helps lead to an arrest or an international wanted notice. The service  hosts Windows desktops  used for FX trading, and a broker has linked unauthorized trades on some of its customers' accounts to logins leaked from the service. GMO says the attackers took customer information. It received a demand for about  $50 million (about ¥8 billion)  on October 21 from people it believes carried out the attack. They have also threatened its customers' trading accounts and data. On October 27, the attackers posted material on their website that they say is information about GMO and its customers. The site's domain, including its mirror sites,  was shut down  at about 4 a.m. Japan time on O...

The North Korea-linked Lazarus Group has been attributed to a cyber espionage campaign dubbed Operation FlashHole targeting at least three organizations in South Korea spanning the construction, software, and wire-communication equipment manufacturing sectors. According to Russian cybersecurity company Kaspersky, the campaign has been active since at least July 2025. It's assessed to pick up from where Operation SyncHole left off. "The group targeted victims more selectively, sending spear‑phishing emails with links to fabricated but relevant sites, such as portfolio and résumé pages tailored to each target," Sojun Ryu, senior security researcher at Kaspersky GReAT, said in an exhaustive analysis. Operation SyncHole was first documented by Kaspersky in April 2025, detailing the state-sponsored adversary's targeting of South Korea's software, IT, financial, semiconductor manufacturing, and telecommunications industries since November 2024 to deliver malwa...

A criminal using the Amadey malware can no longer access or steal data from 180,000 infected computers around the world, including some in Australia, the Australian Signals Directorate (ASD) says. The agency's operators gained access to the criminal's operation's backend and cut it off from those computers. "The next steps that we took were to disconnect that Amadey controller from all those victims," Tauri Gregory, ASD's acting deputy director-general of intelligence,  told ABC News  in an interview published on October 27. ASD is Australia's foreign signals intelligence and cyber security agency. Its  offensive cyber operations  need explicit approval from the Australian government and can disrupt cybercriminals overseas by disabling their infrastructure. Amadey was sold to criminals as a service in 2018, according to  ESET's analysis of Amadey . Each buyer runs its own control panel on its own servers. Computers infected with Amadey check ...

An unknown threat actor has infected 953 online stores, most of them running Magento, as part of a long-running campaign active since July 2025. According to Dutch e-commerce security company Sansec, the activity is designed to add a small piece of code to the store's pages that, when visited by unsuspecting users, serves malicious JavaScript loader code through Magento CMS blocks. "When you visit, that code makes your browser ask the group's server what to do next," Sansec said . "The server first checks whether you are a real shopper or a security scanner, so scanners get nothing." No less than five distinct domains have been observed over time in connection with the campaign - manulfie[.]click, first seen in July 2025 neswnsssn[.]click, first seen in December 2025 lanhd6549tdhse[.]top, first seen in March 2026 additionalver[.]com, first seen in June 2026 deepveindrilling[.]com, first seen in October 2026 Sansec said it found deep...

Cybersecurity researchers are calling attention to what they say is a "recurring social engineering pattern" across hundreds of cases in which threat actors use Microsoft Teams' external chat creation feature to conduct impersonation scams or to deliver malware. "A consistent pattern of attacker behavior has emerged across these incidents: the use of the same throwaway tenants, the same 'IT Support (Internal)' display names, the same remote-access tools, and increasingly, the same payload domains," Arctic Wolf Labs said in a report shared with The Hacker News. The attacks consistently employ IT-themed display names or friendly-sounding first names to subvert external-user warnings in Teams. These messages originate from Teams identities established through newly created or acquired Microsoft 365 tenants. Nearly 30–40% of the cases investigated by the cybersecurity company involve the use of *.onmicrosoft[.]com , a permanent fallback domain auto...
