Although he claims that the attacks “have been largely unsuccessful“, the US company has recognized that so far three entities have been compromised through the use of its notification processes to government institutions.
To avoid derived risks, Microsoft has implemented a series of protection measures, among which is the recommendation to activate multi-factor verification in user accounts.
