Alameda Research, a cryptocurrency trading firm, lost $190 million to fake links in scams perpetrated by a former employee. The scams reportedly involved the former employee sending fake links to Alameda Research employees via email and Slack. The links were designed to look like they were from legitimate cryptocurrency exchanges and wallets. However, when the employees clicked on the links, they were taken to fake websites that stole their login credentials and other sensitive information. The scams were reportedly carried out over a period of several months and were not discovered until Alameda Research conducted a security audit earlier this year. The former employee has been arrested and is facing charges of fraud and wire fraud.
