[求譯] 這段話是什麼意思?

[rita10168 (晉升馬尾女孩)]

DePetrillo and Graham are so-called "white hat" hackers who investigate

and expose security holes that have yet to be plugged by makers of new

computer systems. Tech companies generally appreciate being alerted to

such security issues, which they can then patch before users' personal

information is compromised.


這是摘自CNN網站 一篇講到APPLE iPHONE5s 指紋防盜 高額獎金 徵求駭客突破的文章

本段話中 have yet to be plugged by makers of new computer systems.

have yet to be 是不是就是 have not to be 的意思???

請教一下
