REevil is one of the most active and successful hacking groups connected to Russia and operating all over the world. The group recently demanded a huge bitcoin ransom for an attack targeting IT firm Kaseya in the USA.
Since Tuesday blog and payment site run by REvil group cannot be longer reached without any kind of explanation or why.
The reason behind the disappearance is unknown but has sparked speculation that the group may have been targeted deliberately by authorities.
US President Joe Biden said he raised the issue with Vladimir Putin during a phone call on Friday, after discussing the subject during a summit with the Russian president in Geneva last month.
Mr. Biden told reporters that he had "made it very clear to him...we expect them to act" on information and also hinted the US could take direct digital retaliation on servers used for intrusions.
The timing of Tuesday's outage has sparked speculation that either the US or Russian officials may have taken action against REvil - though officials have so far declined to comment and cyber experts say sudden disappearances of groups are not necessarily uncommon.
The development comes after a series of high-profile ransomware attacks which have hit major US businesses this year.
The FBI accused REvil - also known as Sodinokibi - of being behind a ransomware attack on the world's largest meat processing company JBS last month.
Originally Microsoft has imagined its widgets menu as Microsoft-only widgets but it seems that they have changed their mind.
Due to the latest leak, it seems that Microsoft will open the widgets menu to 3rd party developers as well but at launch, it will be only official widgets. It was hinted that later widgets menu will be open to developers who want to bring their own stuff into it.
Distribution, date, and technology that will need to be used in order to create your widget have not been discussed nor leaked at a given time but in some way, I am very glad that at least some customization will be in Windows 11.
It is funny and amusing how some things that were in Windows Vista are getting back like glass design, round corners, and widgets. Let’s just hope Windows 11 will be a better Windows than Vista was.
