urge The White House computer network operators to take further steps to gauge whether their systems are being targeted amid a breach of the Microsoft Outlook affiliate email program. For a company Microsoft, saying: The latest correction still leaves serious vulnerabilities.
And theHe said White House official: This is an active threat that is still evolving and we are urging network operators to take the matter seriously, adding that senior US security officials are working to determine the next steps to take after the breach.
Separately, CNN reported that the Biden administration was forming a task force to address the breach, and the White House official said in a statement: The administration was making a full government response.
And while Microsoft released a patch last week to fix bugs in Microsoft Outlook, the fix still leaves the back door open allowing compromised servers to be accessed and more attacks to take place.
The White House official said: We cannot emphasize enough that patching and mitigation are not a remedy if servers are compromised, and it is imperative that any organization with a vulnerable server take action to determine if they are targeted.
A source told Reuters: More than 20 thousand American institutions have been hacked because of the breach, which Microsoft blamed on China, although Beijing denies any role for it.
The breach affected credit unions, city governments and small businesses, and left US officials scrambling to reach victims, as the FBI urged them to contact the law enforcement agency.
It appears that those affected are hosting the web versions of Microsoft Outlook email software via their own devices rather than cloud service providers, helping to avoid many large corporations and federal government agencies harm.
A Microsoft representative said: We are working with the government and others to help guide customers, and the company has urged affected customers to apply software updates as soon as possible.
Neither the company nor the White House specified the size of the breach, and Microsoft initially said: It is limited, but the White House last week expressed concern about the possibility of a large number of victims.
The source told Reuters earlier: that so far only a small percentage of infected networks have been penetrated through the back door, but more attacks are expected.
