A Russia-nexus adversary has been linked to 94 new domains starting March 2023, suggesting that the group is actively modifying its infrastructure in response to public disclosures about its activities. Cybersecurity firm Recorded Future linked the revamped infrastructure to a threat actor it tracks under the name  BlueCharlie , a hacking crew that's broadly known by the names Blue Callisto, Callisto (or Calisto), COLDRIVER, Star Blizzard (formerly SEABORGIUM), and TA446. BlueCharlie was previously given the temporary designation Threat Activity Group 53 (TAG-53). "These shifts demonstrate that these threat actors are aware of industry reporting and show a certain level of sophistication in their efforts to obfuscate or modify their activity, aiming to stymie security researchers," the company said in a technical report shared with The Hacker News. BlueCharlie is assessed to be affiliated with Russia's Federal Security Service (FSB), with the threat actor linked

A nascent Go-based malware known as Aurora Stealer is being increasingly deployed as part of multiple campaigns designed to steal sensitive information from compromised hosts. "These infection chains leveraged phishing pages impersonating download pages of legitimate software, including cryptocurrency wallets or remote access tools, and the 911 method making use of YouTube videos and SEO-poised fake cracked software download websites," cybersecurity firm SEKOIA  said . First advertised on Russian cybercrime forums in April 2022 by a threat actor calling themselves Cheshire, Aurora was offered as a commodity malware for other threat actors, describing it as a "multi-purpose botnet with stealing, downloading and remote access capabilities." In the intervening months, the malware has been scaled down to a stealer that can harvest files of interest, data from 40 cryptocurrency wallets, and applications like Telegram. Aurora also comes with a loader that can deploy

It's been a decade since the National Institute of Standards and Technology (NIST) introduced its Cybersecurity Framework (CSF) 1.0. Created following a 2013 Executive Order, NIST was tasked with designing a voluntary cybersecurity framework that would help organizations manage cyber risk, providing guidance based on established standards and best practices. While this version was originally tailored for Critical infrastructure, 2018's version 1.1 was designed for any organization looking to address cybersecurity risk management.  CSF is a valuable tool for organizations looking to evaluate and enhance their security posture. The framework helps security stakeholders understand and assess their current security measures, organize and prioritize actions to manage risks, and improve communication within and outside organizations using a common language. It's a comprehensive collection of guidelines, best practices, and recommendations, divided into five core functions: Identify, Protec
