🛡️ A commentator describes encountering a fake CAPTCHA scam that fingerprinted devices and served different payloads based on user environment. The attacker’s TDS (Traffic Distribution System) delivered benign pages to datacenter IPs used by scanners, while residential and mobile IPs received malicious payloads. The scam prompted a pop-up asking users to press Windows key + R and execute code, and the poster notes they avoid this by using Linux without faked user agents.

🛡️ A widespread malvertising campaign uses fake Solana, Luno, and TradingView pages with malicious JavaScript that assembles malware directly in the browser's memory. The operation, active since late 2024 across 12 countries, filters out researchers and scanners while delivering customized payloads to retail traders and crypto investors. Confiant found the pages register service and shared workers to piece together a unique executable from remote components and local bytes, avoiding transmission of a finished file to evade detection.

🔔 Apple has begun sending Lock Screen notifications to iPhones and iPads running older versions of iOS and iPadOS, warning users of active web-based attacks and urging them to install a critical update. The alert follows Apple guidance and reports of exploit kits — notably Coruna and DarkSword — used to deliver malware via compromised websites. Users unable to update are advised to enable Lockdown Mode where available. Apple says it is aware of attacks; Kaspersky analysis links Coruna to the Operation Triangulation framework, and researchers warn the kits could democratize zero-day exploits.

⚠️ Check Point researchers uncovered a long-running operation that uploaded and promoted over 3,000 YouTube videos linking to malware downloads. The network, dubbed the YouTube Ghost Network, has been active since 2021 and saw its volume triple this year, using hacked channels and a role-based structure to sustain distribution. Videos offering pirated software and Roblox cheats pointed users to cloud-hosted files or phishing pages that deployed stealers and Node.js loaders, and Google has removed the majority of identified content.

🔒 Visiting a suspicious link or scanning an unknown QR code can be risky even if you refrain from entering data or interacting further. Modern webpages can trigger drive-by downloads, exploit browser or plugin vulnerabilities via embedded JavaScript, or silently harvest device and browser metadata to build a digital fingerprint. The piece advises keeping devices patched, avoiding unknown links or QR codes, inspecting URLs and using unshortening and reputation services to vet destinations before proceeding.

🔍 Threat actors used Google ads to promote a fraudulent AppSuite PDF Editor that silently delivered the TamperedChef infostealer. Multiple domains hosted signed installers with revoked certificates; the malicious payload was activated after a delay and is launched with the "-fullupdate" argument, checking for security agents and extracting browser secrets via DPAPI. Operators also pushed related apps such as OneStart, ManualFinder and Epibrowser, and in some cases converted hosts into residential proxies; Truesec and Expel published IoCs for detection.
