An attacker drained 1,196 Bitcoin addresses in 41 minutes on July 30, taking 1,082.65 BTC worth about $70.2 million at the time. Galaxy Research mapped the sweep and tied it to a firmware flaw in Coldcard, the Bitcoin-only hardware wallet made by Canadian firm Coinkite. A March 2021 firmware integration error routed seed generation to a deterministic software pseudorandom number generator (PRNG

Attackers modified a JavaScript file served by advertising technology company Adform, turning it into a browser-side tool that rewrites cryptocurrency wallet addresses. Adform detected the incident on July 27, 2026, removed the malicious code, notified affected clients, and reported it to authorities. Anyone who visited a site carrying the affected script on July 27 and copied a Bitcoin,

Adobe has released security updates to address a maximum-severity security flaw in Campaign Classic (ACC), its enterprise-focused marketing automation platform, that could result in arbitrary code execution. The vulnerability, tracked as CVE-2026-48449, carries a severity score of 10.0 on the CVSS scoring system. It has been described as a case of incorrect authorization that could result in

A fake browser update served over hijacked hotel Wi-Fi has been used to deliver CornFlake, a remote access trojan (RAT) that can capture webcam images, microphone audio, and keystrokes, Microsoft said in its latest report. Researchers track the operation as CaptiveCrunch and attribute it to Storm-2945. It assesses Storm-2945 to be an operational sub-cluster of Midnight Blizzard, also known as

A Chinese-speaking threat actor is suspected to be behind a fresh wave of cyber attacks targeting government organizations mainly located in Central Asia, including Afghanistan, Kyrgyzstan, Tajikistan, Uzbekistan, Kazakhstan, and the Syrian Arab Republic, since January 2025. These targeted organizations operate across several sectors, such as healthcare, research, government offices,

Cybersecurity researchers have shed light on a previously undocumented Go-based loader framework called HollowFrame and a Rust-based malware family tracked as Matryoshka. According to Blackpoint Cyber, the intrusion sequence begins with a spear-phishing message containing a link to an encrypted archive, which holds a Windows Shortcut (LNK). Executing the file triggers a multi-stage chain that

Bitsight says some cheap Android TV boxes have shipped with apps that rewrite their hardware identity to mimic Samsung, Huawei, Xiaomi, or Vivo phones, then click ads on websites run by the same operators. Researchers named the operation Fuyao and attributed it to Zhejiang Fengwo IoT Technology Co., Ltd., a mainland China company founded in 2019. The same apps have a second job. When a box

Google on Thursday announced that it fixed a whopping 1,072 security bugs in Chrome versions 149 and 150, surpassing the total number of flaws the company fixed across the prior 23 milestones combined. Both versions were released last month. In its latest patch for Chrome 151, released Wednesday, the tech giant resolved 370 flaws, out of which 349 were reported by Google itself. Seven of the

An academic study has disclosed a "widespread class" of security vulnerabilities impacting 4G and 5G core networks that, if successfully exploited, could trigger denial-of-service (DoS) attacks and even session hijacking, allowing an attacker to seize control of a user's network session. The findings have been released by a group of researchers from Singapore's Nanyang Technological University

Device code phishing - the abuse of the OAuth 2.0 device authorization grant to steal access tokens - has evolved from a niche red-team technique to an industrial-scale threat in under six months. Designed for input-constrained devices like smart TVs, printers, and so on, the device authorization login flow has been adopted by a wide range of apps and use-cases that it wasn't originally

Palo Alto Networks' Unit 42 says a Chinese-speaking threat actor used DeepSeek through the open-source Hermes Agent framework to launch attacks autonomously. After an initial Telegram instruction, the agent found internet-facing systems and selected public exploits. The researchers recovered no further operator input in the session. The operator, tracked through the aliases knaithe and KnYuan,

Anthropic on Thursday became the latest artificial intelligence (AI) company to reveal that three of its models, including Claude Opus 4.7, Mythos 5, and an unnamed research model, had breached three unnamed organizations during cybersecurity testing without its knowledge. The AI firm said the earliest incidents date back to April 2026, adding it made the discoveries after launching a "

Threat actors with ties to North Korea have been attributed to a sophisticated macOS malvertising campaign that involves redirecting users to fake web pages displaying a full-screen non-existent update sequence to deliver malware as part of a new iteration of the long-running Contagious Interview campaign. The defining aspect of the attack is that bogus macOS software update screen stealthily

A lot of security still comes down to trusting the wrong screen. This week, that screen might be a login page, an install guide, a recruiter call, or a familiar service behaving slightly wrong. Behind it: reused credentials, exposed systems, quiet loaders, abused trust, and exploit paths that should have been harder. Some defenses improved. The loose parts still got found first. Anyway,

A now-patched vulnerability in Azure Cosmos DB could have let an attacker escape the service's Gremlin query sandbox and obtain full read and write access to databases across customer tenants, according to Wiz. Wiz, which codenamed the chain CosmosEscape, said the exploit chain began with a crafted query against a Gremlin database controlled by the attacker. From there, code execution on a

Hidden instructions in a Word document can make Microsoft 365 Copilot rewrite figures in a report, then copy the same instructions into the finished file. Håkon Måløy disclosed the technique on July 28, 144 days after reporting it to Microsoft. In his proof of concept, the internally generated file triggered the same behavior when it was used in a second Copilot drafting session. Måløy's
