This week’s cyber stories show how fast the online world can turn risky. Hackers are sneaking malware into movie downloads, browser add-ons, and even software updates people trust. Tech giants and governments are racing to plug new holes while arguing over privacy and control. And researchers keep uncovering just how much of our digital life is still wide open. The new Threatsday Bulletin

Cybersecurity researchers have disclosed details of a new fully-featured Windows backdoor called NANOREMOTE that uses the Google Drive API for command-and-control (C2) purposes. According to a report from Elastic Security Labs, the malware shares code similarities with another implant codenamed FINALDRAFT (aka Squidoor) that employs Microsoft Graph API for C2. FINALDRAFT is attributed to a

As enterprises refine their strategies for handling Non-Human Identities (NHIs), Robotic Process Automation (RPA) has become a powerful tool for streamlining operations and enhancing security. However, since RPA bots have varying levels of access to sensitive information, enterprises must be prepared to mitigate a variety of challenges. In large organizations, bots are starting to outnumber

An advanced persistent threat (APT) known as WIRTE has been attributed to attacks targeting government and diplomatic entities across the Middle East with a previously undocumented malware suite dubbed AshTag since 2020. Palo Alto Networks is tracking the activity cluster under the name Ashen Lepus. Artifacts uploaded to the VirusTotal platform show that the threat actor has trained its sights

A high-severity unpatched security vulnerability in Gogs has come under active exploitation, with more than 700 compromised instances accessible over the internet, according to new findings from Wiz. The flaw, tracked as CVE-2025-8110 (CVSS score: 8.7), is a case of file overwrite in the file update API of the Go-based self-hosted Git service. A fix for the issue is said to be currently in the

Google on Wednesday shipped security updates for its Chrome browser to address three security flaws, including one it said has come under active exploitation in the wild. The vulnerability, rated high in severity, is being tracked under the Chromium issue tracker ID "466192044." Unlike other disclosures, Google has opted to keep information about the CVE identifier, the affected component, and

Huntress is warning of a new actively exploited vulnerability in Gladinet's CentreStack and Triofox products stemming from the use of hard-coded cryptographic keys that have affected nine organizations so far. "Threat actors can potentially abuse this as a way to access the web.config file, opening the door for deserialization and remote code execution," security researcher Bryan Masters said.

React2Shell continues to witness heavy exploitation, with threat actors leveraging the maximum-severity security flaw in React Server Components (RSC) to deliver cryptocurrency miners and an array of previously undocumented malware families, according to new findings from Huntress. This includes a Linux backdoor called PeerBlight, a reverse proxy tunnel named CowTunnel, and a Go-based

New research has uncovered exploitation primitives in the .NET Framework that could be leveraged against enterprise-grade applications to achieve remote code execution. WatchTowr Labs, which has codenamed the "invalid cast vulnerability" SOAPwn, said the issue impacts Barracuda Service Center RMM, Ivanti Endpoint Manager (EPM), and Umbraco 8. But the number of affected vendors is likely to be

Three security vulnerabilities have been disclosed in the Peripheral Component Interconnect Express (PCIe) Integrity and Data Encryption (IDE) protocol specification that could expose a local attacker to serious risks. The flaws impact PCIe Base Specification Revision 5.0 and onwards in the protocol mechanism introduced by the IDE Engineering Change Notice (ECN), according to the PCI Special

Cloud security is changing. Attackers are no longer just breaking down the door; they are finding unlocked windows in your configurations, your identities, and your code. Standard security tools often miss these threats because they look like normal activity. To stop them, you need to see exactly how these attacks happen in the real world. Next week, the Cortex Cloud team at Palo Alto Networks

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Tuesday added a security flaw impacting the WinRAR file archiver and compression utility to its Known Exploited Vulnerabilities (KEV) catalog, citing evidence of active exploitation. The vulnerability, tracked as CVE-2025-6218 (CVSS score: 7.8), is a path traversal bug that could enable code execution. However, for exploitation

Microsoft closed out 2025 with patches for 56 security flaws in various products across the Windows platform, including one vulnerability that has been actively exploited in the wild. Of the 56 flaws, three are rated Critical, and 53 are rated Important in severity. Two other defects are listed as publicly known at the time of the release. These include 29 privilege escalation, 18 remote code

Fortinet, Ivanti, and SAP have moved to address critical security flaws in their products that, if successfully exploited, could result in an authentication bypass and code execution. The Fortinet vulnerabilities affect FortiOS, FortiWeb, FortiProxy, and FortiSwitchManager and relate to a case of improper verification of a cryptographic signature. They are tracked as CVE-2025-59718 and

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

Zero Trust helps organizations shrink their attack surface and respond to threats faster, but many still struggle to implement it because their security tools don’t share signals reliably. 88% of organizations admit they’ve suffered significant challenges in trying to implement such approaches, according to Accenture. When products can’t communicate, real-time access decisions break down. The

Google on Monday announced a set of new security features in Chrome, following the company's addition of agentic artificial intelligence (AI) capabilities to the web browser. To that end, the tech giant said it has implemented layered defenses to make it harder for bad actors to exploit indirect prompt injections that arise as a result of exposure to untrusted web content and inflict harm. Chief

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
