A firmware flaw in Coldcard hardware wallets has been linked to the theft of approximately $88.6 million in Bitcoin. Attackers exploited a compromised random number generator, allowing them to reconstruct victims’ private keys without ever accessing their devices. Digital asset research firm Galaxy Research first noted unusual activity on July 30, when an attacker drained about 1,082.65 BTC, valued at around $70.2 million, from 1,196 addresses in a rapid sweep lasting just 41 minutes. By August 1, Galaxy detected additional waves of transactions, bringing the total theft to 1,367.05 BTC…

Mac users searching for Claude installation help have been led into a dangerous trap. A malicious campaign used a paid search result and a fake guide on a legitimate Claude sharing page to persuade victims to paste a command into Terminal. That action started the MacSync information-stealing malware. The campaign shows how software searches can become an entry point for account theft. Rather than exploiting a flaw, the operators relied on trust in a familiar domain, a convincing guide, and a command that looked like an installation step. The result can be stolen browser sessions, passwords…

N-able said attackers exploited an authentication bypass in N-central to gain remote administrative access and reach the customer systems managed through those servers. Its first fix was incomplete. CVE-2026-18577 affects N-central builds prior to 2026.3.1.7. N-able shipped build 2026.3.1.7 on August 2 as the first unaffected version. N-central is the remote monitoring and management platform

XCSSET has returned with a way to target macOS developers. The latest version, v40, hides inside poisoned Xcode projects and can turn a local build into a supply-chain compromise. Once activated, it can spread through other projects, raising risk for developers and the organizations that use their code. The malware family was first documented in 2020, but its campaign shows a move toward stealth and scale. It uses memory-based execution, changing payloads, and short-lived files to reduce visible traces. Developers across South Asia have seen heightened targeting, while infected projects have…

AI is becoming both an attack tool and a high-value target, with attacks by AI-enabled adversaries rising 89 percent in 2025, according to CrowdStrike. The security firm's annual Threat Hunting Report details criminal gangs and nation states using AI throughout the attack chain. Attackers are also targeting organizations' AI infrastructure and poisoning popular software packages to compromise their users. "AI is both the weapon and the target," CrowdStrike counter adversary division senior VP Adam Meyers told reporters. "AI is a high-value attack surface, and it's being used by more and more…

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

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

On Thursday, Google introduced a new AI feature into Google Earth which lets anyone fabricate all sorts of misleading or straight up inaccurate satellite imagery, from making it look like a specific place has suffered a drone strike to manifesting a nuclear plant in Iran. Usually, Google Earth is an exceptionally useful tool for open source intelligence (OSINT) analysts to digitally monitor areas of interest and see how they change over time, say, during a conflict or disaster. Now, Google Earth can easily be used as a tool for disinformation. 💡 Do you work at Google? I would love to hear…
