23pds, the Chief Information Security Officer of SlowMist, tweeted that the cryptocurrency theft Trojan MacOS Stealer has been open-sourced. Previously, its attack source code was sold for 1 BTC, but now that it is open-sourced, more malicious attackers can easily obtain this tool. This may not only allow attackers to have an attack library at their disposal, but may also give rise to more covert and complex attack methods, posing greater challenges to the security of cryptocurrency assets.
