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) instead of the STM32 hardware random number generator (RNG). Block says an attacker who can determine or sufficiently constrain the device UID, timer state, and prior RNG-call history can reproduce candidate output streams offline without accessing the device. Candidate seeds can then be checked by deriving their addresses and comparing them with public blockchain data. Coinkite shipped emergency firmware for every affected model and release track on July 31, but installing it does not repair an existing seed. Coinkite tells owners with exposed seeds to generate a new one on patched f...

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 arbitrary code execution in the context of the current user without requiring any user interaction. The update also resolves another high-severity flaw ( CVE-2026-48448 , CVSS score: 8.6) stemming from SQL injection that could pave the way for arbitrary file reads. "This update addresses critical vulnerabilities that could result in arbitrary code execution and arbitrary file system read," Adobe said in an advisory. The company noted that it's not aware of any of the flaws being exploited in the wild. Both shortcomings have been addressed in ACC v7: 7.4.3 build 9398 for W...

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 vulnerabilities have been marked critical in severity. The development comes amid an exponential surge in vulnerability discovery, mainly fueled by the advent of large language models (LLMs) that have accelerated the process, leading to an unprecedented spike in new bug reports, so much so that issues are being flagged at a faster rate than companies can fix them. According to statistics shared by the U.S. National Vulnerabilities Database (NVD), 46,872 flaws have been recorded so far in 2026, nearing the 49,920 vulnerabilities reported for the entirety of 2025.

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 in a paper titled "Understanding Implicit Trust Errors in Core Carrier Networks through Multi-Agent Flaw Discovery and Analysis." The study has uncovered dozens of vulnerabilities in the signaling interfaces of LTE/5G core networks, and specifically covers two LTE implementations (Open5GS and OpenAirInterface) and five 5G implementations (Open5GS, free5GC, OpenAirInterface, SD-Core, and eUPF) across two core signaling protocols, GPRS Tunnelling Protocol Control Plane ( GTP-C ) and Packet Forwarding Control Protocol ( PFCP ). "Our research finds these vulne...

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 , launched exploitation attempts against more than 460 targets using autonomous and conventional workflows. Unit 42 described seven exploit tracks. They span eight Common Vulnerabilities and Exposures (CVE) identifiers because the n8n chain combines two vulnerabilities. The DeepSeek-led attacks against Langflow and n8n failed because the exposed systems did not meet the exploits' configuration requirements. In separate manual operations, Unit 42 reported data exfiltration from three organizations through the NetScaler memory-overread flaw CVE-2026-3055 and command execution on 11...
