‘ShadowHammer’ Spreads Across Online Gaming Supply Chain

A sophisticated supply-chain attack dubbed Operation ShadowHammer is becoming more pervasive, with the group targeting online gamers, security researchers warn.

On Tuesday, Kaspersky Lab, which first took note of ShadowHammer in March, released new research that shows the threat group targeting at least three video game suppliers in Asia as well as three other firms, including another online gaming supplier, a conglomerate holding company and a pharmaceutical firm based in South Korea.

Kaspersky previously reported that PC maker Asus and the third-party supplier of the company’s Live Update Utility software were the first targets of ShadowHammer, although the researchers warned that the attacks focused on infecting the supply chains of many different kinds of enterprises.
