The China-aligned threat actor known as Mustang Panda has been observed using an updated version of a backdoor called TONESHELL and a previously undocumented USB worm called SnakeDisk. "The worm only executes on devices with Thailand-based IP addresses and drops the Yokai backdoor," IBM X-Force researchers Golo Mühr and Joshua Chung said in an analysis published last week. The tech giant's

Russian military exercises near NATO borders follow the recent incursion of Russian drones into the airspace of Poland and Romania, further stoking tensions with the West.

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
