A Russian programmer accused of donating money to Ukraine had his Android device secretly implanted with spyware by the Federal Security Service (FSB) after he was detained earlier this year. The findings come as part of a collaborative investigation by First Department and the University of Toronto's Citizen Lab . "The spyware placed on his device allows the operator to track a target device's location, record phone calls, keystrokes, and read messages from encrypted messaging apps, among other capabilities," according to the report. In May 2024, Kirill Parubets was released from custody after a 15-day period in administrative detention by Russian authorities, during which time his phone, an Oukitel WP7 phone running Android 10, was confiscated from him. During this period, not only was he beaten to compel him into revealing his device password, he was also subjected to an "intense effort" to recruit him as an informant for the FSB, or else risk fac...

Cybersecurity researchers have disclosed multiple security flaws impacting open-source machine learning (ML) tools and frameworks such as MLflow, H2O, PyTorch, and MLeap that could pave the way for code execution. The vulnerabilities, discovered by JFrog, are part of a broader collection of 22 security shortcomings the supply chain security company first disclosed last month. Unlike the first set that involved flaws on the server-side, the newly detailed ones allow exploitation of ML clients and reside in libraries that handle safe model formats like Safetensors . "Hijacking an ML client in an organization can allow the attackers to perform extensive lateral movement within the organization," the company said . "An ML client is very likely to have access to important ML services such as ML Model Registries or MLOps Pipelines." This, in turn, could expose sensitive information such as model registry credentials, effectively permitting a malicious actor to back...

The threat actors behind the More_eggs malware have been linked to two new malware families, indicating an expansion of its malware-as-a-service (MaaS) operation. This includes a novel information-stealing backdoor called RevC2 and a loader codenamed Venom Loader, both of which are deployed using VenomLNK , a staple tool that serves as an initial access vector for the deployment of follow-on payloads. "RevC2 uses WebSockets to communicate with its command-and-control (C2) server. The malware is capable of stealing cookies and passwords, proxies network traffic, and enables remote code execution (RCE)," Zscaler ThreatLabz researcher Muhammed Irfan V A said . "Venom Loader is a new malware loader that is customized for each victim, using the victim's computer name to encode the payload." Both the malware families have been distributed as part of campaigns observed by the cybersecurity company between August and October 2024. The threat actor behind the e-cr...

The threat actor known as Gamaredon has been observed leveraging Cloudflare Tunnels as a tactic to conceal its staging infrastructure hosting a malware called GammaDrop. The activity is part of an ongoing spear-phishing campaign targeting Ukrainian entities since at least early 2024 that's designed to drop the Visual Basic Script malware, Recorded Future's Insikt Group said in a new analysis. The cybersecurity company is tracking the threat actor under the name BlueAlpha, which is also known as Aqua Blizzard, Armageddon, Hive0051, Iron Tilden, Primitive Bear, Shuckworm, Trident Ursa, UAC-0010, UNC530, and Winterflounder. The group, believed to be active since 2014, is affiliated with Russia's Federal Security Service (FSB). "BlueAlpha has recently started using Cloudflare Tunnels to conceal staging infrastructure used by GammaDrop , an increasingly popular technique used by cybercriminal threat groups to deploy malware," Insikt Group noted . "BlueAl...
