Technical details
Source-Supported Details
Source excerpt: "Having two companies victimized at once was already unusual, and upon further investigation we found that Netronix had also been attacked; all three companies belong to the Netronix Group, which may indicate that the hackers are growing bolder or that multiple subsidiaries within the same group share common security weaknesses." [1].

“一次有兩家公司受害，情況頗不尋常，經過進一步追查，我們發現振曜科技（Netronix）也遭受攻擊，而這三家公司皆隸屬振曜集團，這可能意味駭客膽子越來越大，或是同一集團的多家子公司可能有共通資安弱點。”
