A POC to disable TamperProtection and other Defender / MDE components
It is possible to abuse SYSTEM / TrustedInstaller privileges to tamper or delete WdFilter settings (ALTITUDE regkey) and unload the kernel minidriver to disable Tamper protection and other Defender components. This also affects Microsoft's Defender for Endpoint (MDE), blinding MDE of telemetry and activity performed on a target.
This vulnerability, during testing was found to affect the following versions of Windows:
• Windows Server 2022 until BuildLabEx Version: 20348.1.amd64fre.fe_release.210507-1500 (April 2024 update) • Windows Server 2019 • Windows 10 until BuildLabEx Version: 19041.1.amd64fre.vb_release.191206-1406 (April 2024 update) • Windows 11 until BuildLabEx Version: 22621.1.amd64fre.ni_release.220506-1250 (Sep 2023 update).

Bitcoin mining is the process of adding new transactions to the Bitcoin blockchain. It’s a tough job. People who choose to mine Bitcoin use a process called proof of work, deploying computers in a race to solve mathematical puzzles that verify transactions.To entice miners to keep racing to solve the puzzles and support the overall system, the Bitcoin code rewards miners with new Bitcoins. “This is how new coins are created” and new transactions are added to the blockchain, says Okoro.
What Is Bitcoin?
Bitcoin is a decentralized digital currency that you can buy, sell and exchange directly, without an intermediary like a bank. Bitcoin’s creator, Satoshi Nakamoto, originally described the need for “an electronic payment system based on cryptographic proof instead of trust.” Each and every Bitcoin transaction that’s ever been made exists on a public ledger accessible to everyone, making transactions hard to reverse and difficult to fake. That’s by design: Core to their decentralized nature, Bitcoins aren’t backed by the government or any issuing institution, and there’s nothing to guarantee their value besides the proof baked in the heart of the system. “The reason why it’s worth money is simply because we, as people, decided it has value—same as gold,” says Anton Mozgovoy, co-founder & CEO of digital financial service company Holyheld.
