chicksdaddy writes Reuters has the scoop this morning on a new report out from the folks at FireEye about a cyber espionage ring that targets financial services firms. The campaign, dubbed FIN4 by FireEye, stole corporate secrets for the purpose of gaming the stock market. FireEye believes that the extensive cyber operation compromised sensitive data about dozens of publicly held companies. According to the report, the victims include financial services firms and those in related sectors, including investment bankers, attorneys and investor relations firms. Rather than attempting to break into networks overtly, the attackers targeted employees within each organization. Phishing e-mail messages led victims to bogus web sites controlled by the hackers, who harvested login credentials to e-mail and social media accounts. Those accounts were then used to expand the hackers' reach within the target organization: sending phishing email messages to other employees.
