Golden Finance reported that SlowMist Chief Information Security Officer 23pds tweeted that the cryptocurrency theft Trojan MacOS Stealer was open sourced. Previously, its attack source code was sold for 1 BTC, but now being open source means that more malicious attackers can easily obtain this tool. This may not only give attackers an attack library, but may also spawn more covert and complex attack methods, posing greater challenges to the security of cryptocurrency assets.
