Threat actors with ties to North Korea have likely become the latest to exploit the recently disclosed critical React2Shell security flaw in React Server Components (RSC) to deliver a previously undocumented remote access trojan dubbed EtherRAT.
“EtherRAT leverages Ethereum smart contracts for command-and-control (C2) resolution, deploys five independent Linux persistence mechanisms, and

Four distinct threat activity clusters have been observed leveraging a malware loader known as CastleLoader, strengthening the previous assessment that the tool is offered to other threat actors under a malware-as-a-service (MaaS) model.
The threat actor behind CastleLoader has been assigned the name GrayBravo by Recorded Future’s Insikt Group, which was previously tracking it as TAG-150. The

The threat actor known as Storm-0249 is likely shifting from its role as an initial access broker to adopt a combination of more advanced tactics like domain spoofing, DLL side-loading, and fileless PowerShell execution to facilitate ransomware attacks.
“These methods allow them to bypass defenses, infiltrate networks, maintain persistence, and operate undetected, raising serious concerns for

Canadian organizations have emerged as the focus of a targeted cyber campaign orchestrated by a threat activity cluster known as STAC6565.
Cybersecurity company Sophos said it investigated almost 40 intrusions linked to the threat actor between February 2024 and August 2025. The campaign is assessed with high confidence to share overlaps with a hacking group known as Gold Blade, which is also

Cybersecurity researchers have discovered two new extensions on Microsoft Visual Studio Code (VS Code) Marketplace that are designed to infect developer machines with stealer malware.
The VS Code extensions masquerade as a premium dark theme and an artificial intelligence (AI)-powered coding assistant, but, in actuality, harbor covert functionality to download additional payloads, take

Cybersecurity researchers are calling attention to a new campaign dubbed JS#SMUGGLER that has been observed leveraging compromised websites as a distribution vector for a remote access trojan named NetSupport RAT.
The attack chain, analyzed by Securonix, involves three main moving parts: An obfuscated JavaScript loader injected into a website, an HTML Application (HTA) that runs encrypted

It’s been a week of chaos in code and calm in headlines. A bug that broke the internet’s favorite framework, hackers chasing AI tools, fake apps stealing cash, and record-breaking cyberattacks — all within days. If you blink, you’ll miss how fast the threat map is changing.
New flaws are being found, published, and exploited in hours instead of weeks. AI-powered tools meant to help developers

The holiday season compresses risk into a short, high-stakes window. Systems run hot, teams run lean, and attackers time automated campaigns to get maximum return. Multiple industry threat reports show that bot-driven fraud, credential stuffing and account takeover attempts intensify around peak shopping events, especially the weeks around Black Friday and Christmas. 
Why holiday peaks

The Iranian hacking group known as MuddyWater has been observed leveraging a new backdoor dubbed UDPGangster that uses the User Datagram Protocol (UDP) for command-and-control (C2) purposes.
The cyber espionage activity targeted users in Turkey, Israel, and Azerbaijan, according to a report from Fortinet FortiGuard Labs.
“This malware enables remote control of compromised systems by allowing

Over 30 security vulnerabilities have been disclosed in various artificial intelligence (AI)-powered Integrated Development Environments (IDEs) that combine prompt injection primitives with legitimate features to achieve data exfiltration and remote code execution.
The security shortcomings have been collectively named IDEsaster by security researcher Ari Marzouk (MaccariTA). They affect popular
