Cybersecurity researchers have uncovered a malicious Chrome extension that poses as a legitimate Ethereum wallet but harbors functionality to exfiltrate users' seed phrases. The name of the extension is "Safery: Ethereum Wallet," with the threat actor describing it as a "secure wallet for managing Ethereum cryptocurrency with flexible settings." It was uploaded to the Chrome Web Store on September 29, 2025, and was updated as recently as November 12. It's still available for download as of writing. "Marketed as a simple, secure Ethereum (ETH) wallet, it contains a backdoor that exfiltrates seed phrases by encoding them into Sui addresses and broadcasting microtransactions from a threat actor-controlled Sui wallet," Socket security researcher Kirill Boychenko said . Specifically, the malware present within the browser add-on is designed to steal wallet mnemonic phrases by encoding them as fake Sui wallet addresses and then using micro-transact...

Malware families like Rhadamanthys Stealer , Venom RAT , and the Elysium botnet have been disrupted as part of a coordinated law enforcement operation led by Europol and Eurojust. The activity, which is taking place between November 10 and 13, 2025, marks the latest phase of Operation Endgame , an ongoing operation designed to take down criminal infrastructures and combat ransomware enablers worldwide.

The comfort zone in cybersecurity is gone. Attackers are scaling down, focusing tighter, and squeezing more value from fewer, high-impact targets. At the same time, defenders face growing blind spots — from spoofed messages to large-scale social engineering. This week's findings show how that shrinking margin of safety is redrawing the threat landscape. Here's what's making headlines. Hijack Loader expands its reach in Latin America LATAM Targeted by PureHVNC Phishing emails containing SVG file attachments targeting Colombian, Spanish-speaking individuals with themes relating to the Attorney General's office of Colombia have been used to deliver PureHVNC RAT .

Security, trust, and stability — once the pillars of our digital world — are now the tools attackers turn against us. From stolen accounts to fake job offers, cybercriminals keep finding new ways to exploit both system flaws and human behavior. Each new breach proves a harsh truth: in cybersecurity, feeling safe can be far more dangerous than being alert. Here's how that false sense of security was broken again this week. ⚡ Threat of the Week Newly Patched Critical Microsoft WSUS Flaw Comes Under Attack — Microsoft released out-of-band security updates to patch a critical-severity Windows Server Update Service (WSUS) vulnerability that has since come under active exploitation in the wild.

Cybersecurity researchers have uncovered a new supply chain attack targeting the NuGet package manager with malicious typosquats of Nethereum , a popular Ethereum .NET integration platform, to steal victims' cryptocurrency wallet keys. The package, Netherеum.All , has been found to harbor functionality to decode a command-and-control (C2) endpoint and exfiltrate mnemonic phrases, private keys, and keystore data, according to security company Socket. The library was uploaded by a user named " nethereumgroup " on October 16, 2025. It was taken down from NuGet for violating the service's Terms of Use four days later. What's notable about the NuGet package is that it swaps the last occurrence of the letter "e" with the Cyrillic homoglyph "e" (U+0435) to fool unsuspecting developers into downloading it. In a further attempt to increase the credibility of the package, the threat actors have resorted to artificially inflating the download counts...

Meta on Tuesday said it's launching new tools to protect Messenger and WhatsApp users from potential scams. To that end, the company said it's introducing new warnings on WhatsApp when users attempt to share their screen with an unknown contact during a video call so as to prevent them from giving away sensitive information like bank details or verification codes. On Messenger, users can opt to enable a setting called "Scam detection" by navigating to Privacy & safety settings. Once it's turned on, users are alerted when they receive a potentially suspicious message from an unknown connection that may contain signs of a scam. "Because detection happens on your device, chats with end-to-end encryption stay secure," Meta said in a support document. "If you're notified that a chat may contain signs of a scam, we'll ask if you'd like to send recent messages you received to AI review. Messages that are shared with AI are no longer end-...
