In nearly every segment of our lives, AI (artificial intelligence) now makes a significant impact: It can deliver better healthcare diagnoses and treatments; detect and reduce the risk of financial fraud; improve inventory management; and serve up the right recommendation for a streaming movie on Friday night. However, one can also make a strong case that some of AI's most significant impacts are in cybersecurity. AI's ability to learn, adapt, and predict rapidly evolving threats has made it an indispensable tool in protecting the world's businesses and governments. From basic applications like spam filtering to advanced predictive analytics and AI-assisted response, AI serves a critical role on the front lines, defending our digital assets from cyber criminals. The future for AI in cybersecurity is not all rainbows and roses, however. Today we can see the early signs of a significant shift, driven by the democratization of AI technology. While AI continues to empower organizations ...

As 2025 draws to a close, security professionals face a sobering realization: the traditional playbook for web security has become dangerously obsolete. AI-powered attacks, evolving injection techniques, and supply chain compromises affecting hundreds of thousands of websites forced a fundamental rethink of defensive strategies. Here are the five threats that reshaped web security this year, and why the lessons learned will define digital protection for years to come. 1. Vibe Coding Natural language coding, " vibe coding " , transformed from novelty to production reality in 2025, with nearly 25% of Y Combinator startups using AI to build core codebases. One developer launched a multiplayer flight simulator in under three hours, eventually scaling it to 89,000 players and generating thousands in monthly revenue. The Result Code that functions perfectly yet contains exploitable flaws, bypassing traditional security tools. AI generates what you ask for, not what you forget...

It's been a week of chaos in code and calm in headlines. A bug that broke the internet's favorite framework, hackers chasing AI tools, fake apps stealing cash, and record-breaking cyberattacks — all within days. If you blink, you'll miss how fast the threat map is changing. New flaws are being found, published, and exploited in hours instead of weeks. AI-powered tools meant to help developers are quickly becoming new attack surfaces. Criminal groups are recycling old tricks with fresh disguises — fake apps, fake alerts, and fake trust. Meanwhile, defenders are racing to patch systems, block massive DDoS waves, and uncover spy campaigns hiding quietly inside networks. The fight is constant, the pace relentless. For a deeper look at these stories, plus new cybersecurity tools and upcoming expert webinars, check out the full ThreatsDay Bulletin. ⚡ Threat of the Week Max Severity React Flaw Comes Under Attack — A critical security flaw impacting React Server Components (RSC) has ...

Think your Wi-Fi is safe? Your coding tools? Or even your favorite financial apps? This week proves again how hackers, companies, and governments are all locked in a nonstop race to outsmart each other. Here's a quick rundown of the latest cyber stories that show how fast the game keeps changing. DeFi exploit drains funds Critical yETH Exploit Used to Steal $9M A critical exploit targeting Yearn Finance's yETH pool on Ethereum has been exploited by unknown threat actors, resulting in the theft of approximately $9 million from the protocol. The attack is said to have abused a flaw in how the protocol manages its internal accounting, stemming from the fact that a cache containing calculated values to save on gas fees was never cleared when the pool was completely emptied. "The attacker achieved this by minting an astronomical number of tokens – 235 septillion yETH (a 41-digit number) – while depositing only 16 wei, worth approxim...

The threat actor known as Water Saci is actively evolving its tactics, switching to a sophisticated, highly layered infection chain that uses HTML Application (HTA) files and PDFs to propagate via WhatsApp a worm that deploys a banking trojan in attacks targeting users in Brazil. The latest wave is characterized by the attackers shifting from PowerShell to a Python-based variant that spreads the malware in a worm-like manner over WhatsApp Web. "Their new multi-format attack chain and possible use of artificial intelligence (AI) to convert propagation scripts from PowerShell to Python exemplifies a layered approach that has enabled Water Saci to bypass conventional security controls, exploit user trust across multiple channels, and ramp up their infection rates," Trend Micro researchers Jeffrey Francis Bonaobra, Sarah Pearl Camiling, Joe Soares, Byron Gelera, Ian Kenefick, and Emmanuel Panopio said . In these attacks, users receive messages from trusted contacts on WhatsA...

Hackers aren't kicking down the door anymore. They just use the same tools we use every day — code packages, cloud accounts, email, chat, phones, and "trusted" partners — and turn them against us. One bad download can leak your keys. One weak vendor can expose many customers at once. One guest invite, one link on a phone, one bug in a common tool, and suddenly your mail, chats, repos, and servers are in play. Every story below is a reminder that your "safe" tools might be the real weak spot. ⚡ Threat of the Week Shai-Hulud Returns with More Aggression — The npm registry was targeted a second time by a self-replicating worm that went by the moniker "Sha1-Hulud: The Second Coming," affecting over 800 packages and 27,000 GitHub repositories. Like in the previous iteration, the main objective was to steal sensitive data like API keys, cloud credentials, and npm and GitHub authentication information, and facilitate deeper supply chain compromise in a worm-like fashion. Th...

Power doesn't just disappear in one big breach. It slips away in the small stuff—a patch that's missed, a setting that's wrong, a system no one is watching. Security usually doesn't fail all at once; it breaks slowly, then suddenly. Staying safe isn't about knowing everything—it's about acting fast and clear before problems pile up. Clarity keeps control. Hesitation creates risk. Here are this week's signals—each one pointing to where action matters most. ⚡ Threat of the Week Ghost Tap NFC-Based Mobile Fraud Takes Off — A new Android trojan called PhantomCard has become the latest malware to abuse near-field communication (NFC) to conduct relay attacks for facilitating fraudulent transactions in attacks targeting banking customers in Brazil. In these attacks, users who end up installing the malicious apps are instructed to place their credit/debit card on the back of the phone to begin the verification process, only for the card data to be sent to an attacker-controlled NFC relay...

Every week, the cyber world reminds us that silence doesn't mean safety. Attacks often begin quietly — one unpatched flaw, one overlooked credential, one backup left unencrypted. By the time alarms sound, the damage is done. This week's edition looks at how attackers are changing the game — linking different flaws, working together across borders, and even turning trusted tools into weapons. From major software bugs to AI abuse and new phishing tricks, each story shows how fast the threat landscape is shifting and why security needs to move just as quickly. ⚡ Threat of the Week Dozens of Orgs Impacted by Exploitation of Oracle EBS Flaw — Dozens of organizations may have been impacted following the zero-day exploitation of a security flaw in Oracle's E-Business Suite (EBS) software since August 9, 2025, according to Google Threat Intelligence Group (GTIG) and Mandiant. The activity, which bears some hallmarks associated with the Cl0p ransomware crew, is assessed to have fashio...

The security landscape now moves at a pace no patch cycle can match. Attackers aren't waiting for quarterly updates or monthly fixes—they adapt within hours, blending fresh techniques with old, forgotten flaws to create new openings. A vulnerability closed yesterday can become the blueprint for tomorrow's breach. This week's recap explores the trends driving that constant churn: how threat actors reuse proven tactics in unexpected ways, how emerging technologies widen the attack surface, and what defenders can learn before the next pivot. Read on to see not just what happened, but what it means—so you can stay ahead instead of scrambling to catch up. ⚡ Threat of the Week Google Patches Actively Exploited Chrome 0-Day — Google released security updates for the Chrome web browser to address four vulnerabilities, including one that it said has been exploited in the wild. The zero-day vulnerability, CVE-2025-10585, has been described as a type confusion issue in the V8 JavaScript ...

The online world never takes a break, and this week shows why. From ransomware creators being caught to hackers backed by governments trying new tricks, the message is clear: cybercriminals are always changing how they attack, and we need to keep up. Hackers are using everyday tools in harmful ways, hiding spyware in trusted apps, and finding new ways to take advantage of old security gaps. These events aren't random—they show just how clever and flexible cyber threats can be. In this edition, we'll look at the most important cyber events from the past week and share key takeaways to help you stay safe and prepared.

The Computer Emergency Response Team of Ukraine (CERT-UA) has warned that more than 2,000 computers in the country have been infected by a strain of malware called DirtyMoe. The agency  attributed  the campaign to a threat actor it calls  UAC-0027 . DirtyMoe , active since at least 2016, is capable of carrying out cryptojacking and distributed denial-of-service (DDoS) attacks. In March 2022, cybersecurity firm Avast revealed the malware's ability to propagate in a worm-like fashion by taking advantage of known security flaws. The DDoS botnet is known to be delivered by means of another malware referred to as  Purple Fox  or via bogus MSI installer packages for popular software such as Telegram. Purple Fox is also  equipped with a rootkit  that allows the threat actors to  hide the malware  on the machine and make it difficult to detect and remove. The exact initial access vector used in the campaign targeting Ukraine is currently unknow...
