Ukrainian Network FDN3 Launches Massive Brute-Force Attacks on SSL VPN and RDP Devices

Ukrainian Network FDN3 Launches Massive Brute-Force Attacks on SSL VPN and RDP Devices

9月 02, 2025 Cyber Attack / Botnet
Cybersecurity researchers have flagged a Ukrainian IP network for engaging in massive brute-force and password spraying campaigns targeting SSL VPN and RDP devices between June and July 2025. The activity originated from a Ukraine-based autonomous system FDN3 ( AS211736 ), per French cybersecurity company Intrinsec. "We believe with a high level of confidence that FDN3 is part of a wider abusive infrastructure composed of two other Ukrainian networks, VAIZ-AS ( AS61432 ) and ERISHENNYA-ASN ( AS210950 ), and a Seychelles-based autonomous system named TK-NET ( AS210848 )," according to a report published last week. "Those were all allocated in August 2021 and often exchange IPv4 prefixes with one another to evade blocklisting and continue hosting abusive activities." AS61432 currently announces a single prefix 185.156.72[.]0/24, while AS210950 has announced two prefixes 45.143.201[.]0/24 and 185.193.89[.]0/24.

Researchers Find VS Code Flaw Allowing Attackers to Republish Deleted Extensions Under Same Names

Researchers Find VS Code Flaw Allowing Attackers to Republish Deleted Extensions Under Same Names

8月 28, 2025 Malware / Ransomware
Cybersecurity researchers have discovered a loophole in the Visual Studio Code Marketplace that allows threat actors to reuse names of previously removed extensions. Software supply chain security outfit ReversingLabs said it made the discovery after it identified a malicious extension named "ahbanC.shiba" that functioned similarly to two other extensions – ahban.shiba and ahban.cychelloworld – that were flagged earlier this March. All three libraries are designed to act as a downloader to retrieve a PowerShell payload from an external server that encrypts files in a folder called "testShiba" on the victim's Windows desktop and demands a Shiba Inu token by instructing the victim to deposit the assets to an unspecified wallet. These efforts suggest ongoing development attempts by the threat actor. The company said it decided to dig deeper because of the fact that the name of the new extension ("ahbanC.shiba") was virtually the same as one of the t...

Storm-0501 Exploits Entra ID to Exfiltrate and Delete Azure Data in Hybrid Cloud Attacks

8月 27, 2025 Ransomware / Cloud Security
The financially motivated threat actor known as Storm-0501 has been observed refining its tactics to conduct data exfiltration and extortion attacks targeting cloud environments. "Unlike traditional on-premises ransomware, where the threat actor typically deploys malware to encrypt critical files across endpoints within the compromised network and then negotiates for a decryption key, cloud-based ransomware introduces a fundamental shift," the Microsoft Threat Intelligence team said in a report shared with The Hacker News. "Leveraging cloud-native capabilities, Storm-0501 rapidly exfiltrates large volumes of data, destroys data and backups within the victim environment, and demands ransom -- all without relying on traditional malware deployment." Storm-0501 was first documented by Microsoft almost a year ago, detailing its hybrid cloud ransomware attacks targeting government, manufacturing, transportation, and law enforcement sectors in the U.S., with the thr...

Someone Created the First AI-Powered Ransomware Using OpenAI's gpt-oss:20b Model

8月 27, 2025 Ransomware / Artificial Intelligence
Cybersecurity company ESET has disclosed that it discovered an artificial intelligence (AI)-powered ransomware variant codenamed PromptLock . Written in Golang, the newly identified strain uses the gpt-oss:20b model from OpenAI locally via the Ollama API to generate malicious Lua scripts in real-time. The open-weight language model was released by OpenAI earlier this month. "PromptLock leverages Lua scripts generated from hard-coded prompts to enumerate the local filesystem, inspect target files, exfiltrate selected data, and perform encryption," ESET said . "These Lua scripts are cross-platform compatible, functioning on Windows, Linux, and macOS." The ransomware code also embeds instructions to craft a custom note based on the "files affected," and the infected machine is a personal computer, company server, or a power distribution controller. It's currently not known who is behind the malware, but ESET told The Hacker News that PromptLoc arti...
