Hackers are increasingly embedding malware instructions in public blockchain ledgers, creating “dead‑drop” channels that persist even after traditional servers are shut down. Chainalysis reports a 440 % surge in such activity, with daily malicious entries climbing from 2.06 to 11.1 after the rollout of unrestricted AI models. The method uses transaction data or smart‑contract calls on networks such as TRON, Aptos, BNB Chain, Polygon and Bitcoin to store encrypted commands, addresses and configuration details that infected computers can [...]

The 21st September Threat Intelligence Report was released as a generic template containing an extensive dropdown list of countries and territories, but it provides no specific threat data, analysis, or actionable insights. The document appears to be a placeholder or form intended for users to select a nation, yet the body of the report is empty beyond repetitive country names and placeholder fields for personal information. No incidents, actors, vulnerabilities, or recommendations are detailed, and the content lacks [...]

Meta Platforms Inc. has reduced certain internal security measures but remains unable to dismiss a retaliation lawsuit filed by a former cybersecurity professional. The plaintiff, a former Meta security engineer, alleges that after reporting internal vulnerabilities, the company subjected him to adverse employment actions, including demotion and termination. Meta’s recent policy adjustments, aimed at tightening data access protocols, were presented as a response to broader industry pressure for stronger safeguards. However, the court has denied Meta’s motion [...]

A joint cybersecurity advisory from Japan, the U.S., Australia, and Germany revealed that North Korean threat actors behind the Contagious Interview campaign have compromised at least 30,000 devices in more than 100 countries and stolen over $10.71 million in cryptocurrency from 7,000+ wallets. The attackers target web designers, engineers, and blockchain specialists by posing as recruiters on LinkedIn, then deploying malware such as BeaverTail and OtterCookie to gain remote access. The operation, linked to the 313 General Bureau, [...]

SEALSQ Corp, its parent WISeKey International Holding Ltd, and the Swiss Canton of Jura signed a Memorandum of Understanding to create the Jura Post‑Quantum Semiconductor and Cybersecurity Center. The public‑private partnership will invest CHF 40 million to CHF 60 million over six years to develop regional expertise in personalizing, testing, and certifying hardware‑embedded post‑quantum cryptography. The center will use SEALSQ’s QS7001 Quantum Shield microcontrollers, which run NIST‑standard ML‑KEM and ML‑DSA lattice algorithms, and will support defense, aerospace, and critical infrastructure sectors. [...]

Cybersecurity researchers uncovered TASK#STOMP, a PowerShell backdoor that harvests business documents, Wi‑Fi passwords, clipboard data, and screenshots while accepting remote commands via two token‑authenticated C2 servers. Infection begins with a disguised VBScript (“95c9050t66.vbs”) executed through wscript.exe, establishing persistence through scheduled tasks and the Startup folder. The malware employs timestomping, hidden execution, and mutual‑watchdog modules to maintain a single active session and evade detection. It also opens a Chrome window to an Iranian tender database, though the purpose [...]

SEALSQ Corp, WISeKey International Holding, and the Canton of Jura signed a memorandum of understanding to create a Post‑Quantum Semiconductor and Cybersecurity Center in the Swiss canton. The project will invest roughly CHF 40‑60 million over six years, focusing on the QS7001 Quantum Shield and related secure firmware personalization, testing, and certification. The initiative aims to generate about 40 jobs in two years, expanding to over 250 by year eight, with a majority of positions filled by local residents. [...]

SentinelOne revealed that North Korean threat actor Jade Sleet targeted an India‑based IT services firm, deploying Apple macOS backdoors FLATROOF and ROOFDECK. The attack used social‑engineering job‑interview lures to compromise a DevOps engineer’s Apple Silicon MacBook, with the backdoors first detected on March 18, 2026. The implants remained dormant until March 29, then began beaconing, and a newer ROOFDECK variant appeared on April 20, 2026, stripping debug symbols to evade detection. The campaign underscores Jade Sleet’s focus on cryptocurrency and blockchain vendors. [...]
