If you use a smartphone, browse the web, or unzip files on your computer, you are in the crosshairs this week. Hackers are currently exploiting critical flaws in the daily software we all rely on—and in some cases, they started attacking before a fix was even ready.
Below, we list the urgent updates you need to install right now to stop these active threats.
⚡ Threat of the Week
Apple and
In early December 2025, security researchers exposed a cybercrime campaign that had quietly hijacked popular Chrome and Edge browser extensions on a massive scale.
A threat group dubbed ShadyPanda spent seven years playing the long game, publishing or acquiring harmless extensions, letting them run clean for years to build trust and gain millions of installs, then suddenly flipping them into
Cybersecurity researchers have disclosed details of an active phishing campaign that's targeting a wide range of sectors in Russia with phishing emails that deliver Phantom Stealer via malicious ISO optical disc images.
The activity, codenamed Operation MoneyMount-ISO by Seqrite Labs, has primarily singled out finance and accounting entities, with those in the procurement, legal, payroll
The pro-Russian hacktivist group known as CyberVolk (aka GLORIAMIST) has resurfaced with a new ransomware-as-a-service (RaaS) offering called VolkLocker that suffers from implementation lapses in test artifacts, allowing users to decrypt files without paying an extortion fee.
According to SentinelOne, VolkLocker (aka CyberVolk 2.x) emerged in August 2025 and is capable of targeting both Windows
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Friday added a high-severity flaw impacting Sierra Wireless AirLink ALEOS routers to its Known Exploited Vulnerabilities (KEV) catalog, following reports of active exploitation in the wild.
CVE-2018-4063 (CVSS score: 8.8/9.9) refers to an unrestricted file upload vulnerability that could be exploited to achieve remote code
Apple on Friday released security updates for iOS, iPadOS, macOS, tvOS, watchOS, visionOS, and its Safari web browser to address two security flaws that it said have been exploited in the wild, one of which is the same flaw that was patched by Google in Chrome earlier this week.
The vulnerabilities are listed below -
CVE-2025-43529 (CVSS score: N/A) - A use-after-free vulnerability in WebKit
Cybersecurity researchers are calling attention to a new campaign that's leveraging GitHub-hosted Python repositories to distribute a previously undocumented JavaScript-based Remote Access Trojan (RAT) dubbed PyStoreRAT.
"These repositories, often themed as development utilities or OSINT tools, contain only a few lines of code responsible for silently downloading a remote HTA file and executing
Cybersecurity researchers have documented four new phishing kits named BlackForce, GhostFrame, InboxPrime AI, and Spiderman that are capable of facilitating credential theft at scale.
BlackForce, first detected in August 2025, is designed to steal credentials and perform Man-in-the-Browser (MitB) attacks to capture one-time passwords (OTPs) and bypass multi-factor authentication (MFA). The kit
The browser has become the main interface to GenAI for most enterprises: from web-based LLMs and copilots, to GenAI‑powered extensions and agentic browsers like ChatGPT Atlas. Employees are leveraging the power of GenAI to draft emails, summarize documents, work on code, and analyze data, often by copying/pasting sensitive information directly into prompts or uploading files.

The React team has released fixes for two new types of flaws in React Server Components (RSC) that, if successfully exploited, could result in denial-of-service (DoS) or source code exposure.
The team said the issues were found by the security community while attempting to exploit the patches released for CVE-2025-55182 (CVSS score: 10.0), a critical bug in RSC that has since been weaponized in
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has urged federal agencies to patch the recent React2Shell vulnerability by December 12, 2025, amid reports of widespread exploitation.
The critical vulnerability, tracked as CVE-2025-55182 (CVSS score: 10.0), affects the React Server Components (RSC) Flight protocol. The underlying cause of the issue is an unsafe deserialization
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Thursday added a high-severity security flaw impacting OSGeo GeoServer to its Known Exploited Vulnerabilities (KEV) catalog, based on evidence of active exploitation in the wild.
The vulnerability in question is CVE-2025-58360 (CVSS score: 8.2), an unauthenticated XML External Entity (XXE) flaw that affects all versions prior to
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.

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 Unit 42 is tracking the activity cluster under the name Ashen Lepus. Artifacts uploaded to the VirusTotal platform show that the threat actor has trained its
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.
