Attacks that target users in their web browsers have seen an unprecedented rise in recent years. In this article, we’ll explore what a “browser-based attack” is, and why they’re proving to be so effective.
What is a browser-based attack?
First, it’s important to establish what a browser-based attack is.
In most scenarios, attackers don’t think of themselves as attacking your web browser.
In a world where threats are persistent, the modern CISO’s real job isn't just to secure technology—it's to preserve institutional trust and ensure business continuity.
This week, we saw a clear pattern: adversaries are targeting the complex relationships that hold businesses together, from supply chains to strategic partnerships. With new regulations and the rise of AI-driven attacks, the
A new artificial intelligence (AI)-powered penetration testing tool linked to a China-based company has attracted nearly 11,000 downloads on the Python Package Index (PyPI) repository, raising concerns that it could be repurposed by cybercriminals for malicious purposes.
Dubbed Villager, the framework is assessed to be the work of Cyberspike, which has positioned the tools as a red teaming
Chinese-speaking users are the target of a search engine optimization (SEO) poisoning campaign that uses fake software sites to distribute malware.
"The attackers manipulated search rankings with SEO plugins and registered lookalike domains that closely mimicked legitimate software sites," Fortinet FortiGuard Labs researcher Pei Han Liao said. "By using convincing language and small character
The U.S. Federal Bureau of Investigation (FBI) has issued a flash alert to release indicators of compromise (IoCs) associated with two cybercriminal groups tracked as UNC6040 and UNC6395 for orchestrating a string of data theft and extortion attacks.
"Both groups have recently been observed targeting organizations' Salesforce platforms via different initial access mechanisms," the FBI said.
Samsung has released its monthly security updates for Android, including a fix for a security vulnerability that it said has been exploited in zero-day attacks.
The vulnerability, CVE-2025-21043 (CVSS score: 8.8), concerns an out-of-bounds write that could result in arbitrary code execution.
"Out-of-bounds Write in libimagecodec.quram.so prior to SMR Sep-2025 Release 1 allows remote attackers to
Apple has notified users in France of a spyware campaign targeting their devices, according to the Computer Emergency Response Team of France (CERT-FR).
The agency said the alerts were sent out on September 3, 2025, making it the fourth time this year that Apple has notified citizens in the county that at least one of the devices linked to their iCloud accounts may have been compromised as part
Cybersecurity researchers have discovered a new ransomware strain dubbed HybridPetya that resembles the notorious Petya/NotPetya malware, while also incorporating the ability to bypass the Secure Boot mechanism in Unified Extensible Firmware Interface (UEFI) systems using a now-patched vulnerability disclosed earlier this year.
Slovakian cybersecurity company ESET said the samples were uploaded
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Thursday added a critical security flaw impacting Dassault Systèmes DELMIA Apriso Manufacturing Operations Management (MOM) software to its Known Exploited Vulnerabilities (KEV) catalog, based on evidence of active exploitation.
The vulnerability, tracked as CVE-2025-5086, carries a CVSS score of 9.0 out of 10.0. According to
The security landscape for cloud-native applications is undergoing a profound transformation. Containers, Kubernetes, and serverless technologies are now the default for modern enterprises, accelerating delivery but also expanding the attack surface in ways traditional security models can’t keep up with.
As adoption grows, so does complexity. Security teams are asked to monitor sprawling hybrid
A security weakness has been disclosed in the artificial intelligence (AI)-powered code editor Cursor that could trigger code execution when a maliciously crafted repository is opened using the program.
The issue stems from the fact that an out-of-the-box security setting is disabled by default, opening the door for attackers to run arbitrary code on users' computers with their privileges.

Google on Tuesday announced that its new Google Pixel 10 phones support the Coalition for Content Provenance and Authenticity (C2PA) standard out of the box to verify the origin and history of digital content.
To that end, support for C2PA's Content Credentials has been added to Pixel Camera and Google Photos apps for Android. The move, Google said, is designed to further digital media
U.S. Senator Ron Wyden has called on the Federal Trade Commission (FTC) to probe Microsoft and hold it responsible for what he called "gross cybersecurity negligence" that enabled ransomware attacks on U.S. critical infrastructure, including against healthcare networks.
"Without timely action, Microsoft's culture of negligent cybersecurity, combined with its de facto monopolization of the
Threat actors affiliated with the Akira ransomware group have continued to target SonicWall devices for initial access.
Cybersecurity firm Rapid7 said it observed a spike in intrusions involving SonicWall appliances over the past month, particularly following reports about renewed Akira ransomware activity since late July 2025.
SonicWall subsequently revealed the SSL VPN activity aimed at its
Cybersecurity researchers have disclosed two new campaigns that are serving fake browser extensions using malicious ads and fake websites to steal sensitive data.
The malvertising campaign, per Bitdefender, is designed to push fake "Meta Verified" browser extensions named SocialMetrics Pro that claim to unlock the blue check badge for Facebook and Instagram profiles. At least 37 malicious ads
CISOs know their field. They understand the threat landscape. They understand how to build a strong and cost-effective security stack. They understand how to staff out their organization. They understand the intricacies of compliance. They understand what it takes to reduce risk. Yet one question comes up again and again in our conversations with these security leaders: how do I make the impact
Cybersecurity researchers have disclosed details of a new campaign that leverages ConnectWise ScreenConnect, a legitimate Remote Monitoring and Management (RMM) software, to deliver a fleshless loader that drops a remote access trojan (RAT) called AsyncRAT to steal sensitive data from compromised hosts.
"The attacker used ScreenConnect to gain remote access, then executed a layered VBScript and
An advanced persistent threat (APT) group from China has been attributed to the compromise of a Philippines-based military company using a previously undocumented fileless malware framework called EggStreme.
"This multi-stage toolset achieves persistent, low-profile espionage by injecting malicious code directly into memory and leveraging DLL sideloading to execute payloads," Bitdefender
Cybersecurity researchers have discovered two new malware families, including a modular Apple macOS backdoor called CHILLYHELL and a Go-based remote access trojan (RAT) named ZynorRAT that can target both Windows and Linux systems.
According to an analysis from Jamf Threat Labs, ChillyHell is written in C++ and is developed for Intel architectures.
CHILLYHELL is the name assigned to a malware
