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

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

Samsung patched CVE-2025-21043, a critical flaw in its Android devices exploited in live attacks. Users urged to install September 2025 update.

### Summary HMAC signature comparison is not timing-safe and is vulnerable to timing attacks. ### Details `SharedKey::sign()` returns a `Vec<u8>` which has a non-constant-time equality implementation. `Hmac::finalize()` returns a constant-time wrapper ([`CtOutput`](https://docs.rs/digest/0.10.7/digest/struct.CtOutput.html)) which was discarded. Alternatively, `Hmac` has a constant-time `verify()` method. The problem reported here is due to the following lines in `SharedKey::sign()` of the previous code: ```rust let mut mac = HmacSha256::new_from_slice(key).unwrap(); mac.update(data); Ok(mac.finalize().into_bytes().to_vec()) ``` and the merged update changes the third line to directly verify with `verify_slice`. ### Impact Anyone who uses HS256 signature verification is vulnerably to Timing Attack that allows the attacker to forge a signature.

Agentic and AI browsers are here: What are they? Which ones are there? How can they help me? Are they safe to use?

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 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

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

Alongside new iPhones, Apple released a new security architecture on Tuesday: Memory Integrity Enforcement aims to eliminate the most frequently exploited class of iOS bugs.
