Google's threat intelligence team discovered a sophisticated iOS malware called "Ghostblade" designed for one-time execution to steal cryptocurrency private keys, message data, and personal information, then erase all traces after execution. As part of the "DarkSword" toolkit, this tool highlights a shift in cryptocurrency attack methods toward phishing and user deception. In February, total losses from cryptocurrency hacker attacks decreased from $385 million the previous month to approximately $50 million, with individual users becoming the primary attack target.
