Kardashev Scale Quantum Computing for Bitcoin Mining

Bitcoin already faces a quantum threat through Shor attacks on elliptic-curve signatures. This paper isolates the other component that public discussion often conflates with it: mining. Grover's algorithm halves the exponent of brute-force search, promising a quadratic edge to any quantum miner o...

crypto-js PBKDF2 1,000 times weaker than specified in 1993 and 1.3M times weaker than current standard

Impact Summary Crypto-js PBKDF2 is 1,000 times weaker than originally specified in 1993, and at least 1,300,000 times weaker than current industry standardOWASP PBKDF2 Cheatsheet. This is because it both 1 defaults to SHA1SHA1 wiki, a cryptographic hash algorithm considered insecure since at leas...

Split vulnerable to preimage attack

Lines of code Vulnerability details Impact A motivated attacker could invest the resources to craft a malicious SplitsReceiver to steal all of a users' pending funds. Proof of Concept This is a non-practical implementation of the attack, but shows by extending the SplitsReceiver array by any numb...

Gobbler Merkle tree vulnerable to second preimage attack

Lines of code Vulnerability details Impact The Merkle tree is vulnerable to a second preimage attack due to the fact that there is no prefix to distinguish between leaves an intermediate nodes Proof of Concept There are no prefixes added to the values in MerkleProofLib and none included in what's...

Elevating Privileges Via Windows Installers

There’s an odd bit of behavior that some Windows systems will exhibit when certain kinds of installers are launched, automatically elevating the privileges of the installer process to system-level privileges. In theory, the issue shouldn’t be exploitable because at one point in the process the...
