New attack scheme on Office 365 corporate users

KnockKnock is discovered by Skyhigh Networks experts, who noted that the key distinction of this new attack is the nature of the accounts that are being targeted. The attack targets on system accounts that are not assigned to any one individual user. System accounts have more privileges and, in addition, they have a more loyal password policy. Having access to the account, it is easier for hackers to continue attacking the corporate network.
