ThreatsDay Bulletin: $15B Crypto Bust, Satellite Spying, Billion-Dollar Smishing, Android RATs & More

Oct 16, 2025 Cybersecurity / Hacking News
The online world is changing fast. Every week, new scams, hacks, and tricks show how easy it's become to turn everyday technology into a weapon. Tools made to help us work, connect, and stay safe are now being used to steal, spy, and deceive. Hackers don't always break systems anymore — they use them. They hide inside trusted apps, copy real websites, and trick people into giving up control without even knowing it. It's no longer just about stealing data — it's about power, money, and control over how people live and communicate. This week's ThreatsDay issue looks at how that battle is unfolding — where criminals are getting smarter, where defenses are failing, and what that means for anyone living in a connected world. Crypto empire built on slavery Historic Operation Targets SE Asian Scam Networks with $15B Seizure The U.S. government has seized $15 billion (approximately 127,271 bitcoin) worth of cryptocurrency assets from one of the world's largest operators ...

Chinese Threat Group 'Jewelbug' Quietly Infiltrated Russian IT Network for Months

Oct 15, 2025 Cyber Espionage / Threat Intelligence
A threat actor with ties to China has been attributed to a five-month-long intrusion targeting a Russian IT service provider, marking the hacking group's expansion to the country beyond Southeast Asia and South America. The activity, which took place from January to May 2025, has been attributed by Broadcom-owned Symantec to a threat actor it tracks as Jewelbug , which it said overlaps with clusters known as CL-STA-0049 (Palo Alto Networks Unit 42), Earth Alux (Trend Micro), and REF7707 (Elastic Security Labs). The findings suggest Russia is not off-limits for Chinese cyber espionage operations despite increased "military, economic, and diplomatic" relations between Moscow and Beijing over the years. "Attackers had access to code repositories and software build systems that they could potentially leverage to carry out supply chain attacks targeting the company's customers in Russia," the Symantec Threat Hunter Team said in a report shared with The ...

SaaS Breaches Start with Tokens - What Security Teams Must Watch

SaaS Breaches Start with Tokens - What Security Teams Must Watch

Oct 09, 2025 SaaS Security / Identity Management
Token theft is a leading cause of SaaS breaches. Discover why OAuth and API tokens are often overlooked and how security teams can strengthen token hygiene to prevent attacks. Most companies in 2025 rely on a whole range of software-as-a-service (SaaS) applications to run their operations. However, the security of these applications depends on small pieces of data called tokens. Tokens, like OAuth access tokens, API keys, and session tokens, work like keys to these applications. If a cybercriminal gets hold of one, they can access relevant systems without much trouble. Recent security breaches have shown that just one stolen token can bypass multi-factor authentication (MFA) and other security measures. Instead of exploiting vulnerabilities directly, attackers are leveraging token theft. It's a security concern that ties into the broader issue of SaaS sprawl and the difficulty of monitoring countless third-party integrations. Recent Breaches Involving Token Theft A lot of real-wo...
