Consultants have additionally questioned the transparency of LastPass, which fails so far safety incident statements and has nonetheless not set the document straight on precisely when the second assault occurred, nor how a lot time the hacker was contained in the system; the time a hacker has inside a system considerably impacts the quantity of information and techniques that may be exploited.
