We show that an attacker can plant an injection in a website the user is visiting, which silently turns Bing Chat into a Social Engineer who seeks out and exfiltrates personal information. The user doesnt have to ask about the website or do anything except interact with Bing Chat while the website is opened in the browser. --------------------------------------------- https://greshake.github.io/ ∗∗∗ Malware Disguised as Document from Ukraines Energoatom Delivers Havoc Demon Backdoor ∗∗∗ --------------------------------------------- [...] FortiGuard Labs has encountered a malicious spoofed document pretending to be from the Ukrainian company, Energoatom, a state-owned enterprise that operates Ukraine’s nuclear power plants.

The detection opportunities rely on open-source tools (e.g., Velociraptor) and rules (e.g., Yara, Sigma) so they can be used by any company or the wider community. --------------------------------------------- https://sec-consult.com/blog/detail/bumblebee-hunting-with-a-velociraptor/ ∗∗∗ Cryptocurrency Stealer Malware Distributed via 13 NuGet Packages ∗∗∗ --------------------------------------------- Cybersecurity researchers have detailed the inner workings of the cryptocurrency stealer malware that was distributed via 13 malicious NuGet packages as part of a supply chain attack targeting .NET developers.

Unencrypted user data and commands. What could go wrong? A market-leading garage door controller is so riddled with severe security and privacy vulnerabilities that the researcher who discovered them, Sam Sabetan, is advising anyone using one to immediately disconnect it until they are fixed. Each $80 device, used to open and close garage doors and control home security alarms and smart power plugs, employs the same easy-to-find universal password to communicate with Nexx servers. The controllers also broadcast the unencrypted email address, device ID, first name, and last initial corresponding to each one, along with the message required to open or shut a door or turn on or off a smart plug or schedule such a command for a later time.
