Bitdefender has once again been recognized as a Representative Vendor in the Gartner® Market Guide for Managed Detection and Response (MDR) — marking the fourth consecutive year of inclusion. According to Gartner, more than 600 providers globally claim to deliver MDR services, yet only a select few meet the criteria to appear in the Market Guide. While inclusion is not a ranking or comparative assessment, we believe it underscores Bitdefender’s human-driven approach to MDR and our continued alignment with Gartner’s rigorous inclusion standards. To be included, must demonstrate consistent visibility through Gartner client inquiries or Peer Insights reviews, focus on delivering end-user–oriented services rather than purely technological solutions, and represent a variety of company sizes and geographies. We believe independent analyst research like the Gartner Market Guide for Managed Detection and Response is a valuable resource for organizations assessing MDR providers. The rep...

The threat actor known as Curly COMrades has been observed exploiting virtualization technologies as a way to bypass security solutions and execute custom malware. According to a new report from Bitdefender, the adversary is said to have enabled the Hyper-V role on selected victim systems to deploy a minimalistic, Alpine Linux-based virtual machine. "This hidden environment, with its lightweight footprint (only 120MB disk space and 256MB memory), hosted their custom reverse shell, CurlyShell, and a reverse proxy, CurlCat," security researcher Victor Vrabie, along with Adrian Schipor and Martin Zugec, said in a technical report. Curly COMrades was first documented by the Romanian cybersecurity vendor in August 2025 in connection with a series of attacks targeting Georgia and Moldova. The activity cluster is assessed to be active since late 2023, operating with interests that are aligned with Russia. These attacks were found to deploy tools like CurlCat for bidirection...

SonicWall has formally implicated state-sponsored threat actors as behind the September security breach that led to the unauthorized exposure of firewall configuration backup files. "The malicious activity – carried out by a state-sponsored threat actor – was isolated to the unauthorized access of cloud backup files from a specific cloud environment using an API call," the company said in a statement released this week. "The incident is unrelated to ongoing global Akira ransomware attacks on firewalls and other edge devices." SonicWall, however, did not disclose which country was behind the incident or provide any indicators linking it to any known threat actor or group. The disclosure comes nearly a month after the company said an unauthorized party accessed firewall configuration backup files for all customers who have used the cloud backup service. In September, it claimed that the threat actors accessed the backup files stored in the cloud for less than ...

Google on Wednesday said it discovered an unknown threat actor using an experimental Visual Basic Script (VB Script) malware dubbed PROMPTFLUX that interacts with its Gemini artificial intelligence (AI) model API to write its own source code for improved obfuscation and evasion. "PROMPTFLUX is written in VB Script and interacts with Gemini's API to request specific VBScript obfuscation and evasion techniques to facilitate 'just-in-time' self-modification, likely to evade static signature-based detection," Google Threat Intelligence Group (GTIG) said in a report shared with The Hacker News. The novel feature is part of its "Thinking Robot" component, which periodically queries the large language model (LLM), Gemini 1.5 Flash or later in this case, to obtain new code so as to sidestep detection. This, in turn, is accomplished by using a hard-coded API key to send the query to the Gemini API endpoint. The prompt sent to the model is both highly speci...

Cybersecurity researchers have disclosed a new set of vulnerabilities impacting OpenAI's ChatGPT artificial intelligence (AI) chatbot that could be exploited by an attacker to steal personal information from users' memories and chat histories without their knowledge. The seven vulnerabilities and attack techniques, according to Tenable, were found in OpenAI's GPT-4o and GPT-5 models. OpenAI has since addressed some of them .  These issues expose the AI system to indirect prompt injection attacks , allowing an attacker to manipulate the expected behavior of a large language model (LLM) and trick it into performing unintended or malicious actions, security researchers Moshe Bernstein and Liv Matan said in a report shared with The Hacker News. The identified shortcomings are listed below - Indirect prompt injection vulnerability via trusted sites in Browsing Context, which involves asking ChatGPT to summarize the contents of web pages with malicious instructions added...

Raise your hand if you’ve heard the myth, “Android isn’t secure.” Android phones, such as the Samsung Galaxy, unlock new ways of working. But, as an IT admin, you may worry about the security—after all, work data is critical. However, outdated concerns can hold your business back from unlocking its full potential. The truth is, with work happening everywhere, every device connected to your network is a potential security breach point. As threats evolve, so must the tools to defend against them. Allow me to introduce Samsung Knox— a built-in security platform that combines hardware and software protections on Samsung Galaxy devices. It’s loaded with features and is designed to safeguard data, provide IT teams with deeper control, and offer a flexible foundation for enterprise needs. Let’s take a look at some myths about open source and how Samsung can get you on the right path to success. Myth 1: “Isn’t Android more prone to malware and attacks?” Common concerns around sideloadi...
