CISA and the Department of Energy (DOE) are aware of threat actors gaining
access to a variety of internet-connected uninterruptable power supply (UPS)
devices, often through unchanged default usernames and passwords.
Organizations can mitigate attacks against their UPS devices, which provide
emergency power in a variety of applications when normal power sources are
lost, by removing management interfaces from the internet.
CISA發布的聲明中指出，攻擊者通常會透過未變更的預設使用者名稱及密碼，來獲得不同
連網 UPS 的存取權限。所以我們最好能先將預設密碼改成強固密碼或較複雜密碼，至少
可以獲得基本的安全保障。再者，我們可以透過將管理介面從網際網路上移除，便能有效
減緩連網 UPS 被攻擊的可能性。
