I read your news article about a "cyberattaque". The technical
information to stop WannaCry (ransomware) is incorrect. The
iuqerfsodp9ifjaposdfjhgosurijfaewrwergwea[.]com domain name is not a
bug; it is a "kill switch". There is no need to do any
"configuration DNS" change as the domain name was registered on May
12 by a person in the United Kingdom [1] identified as
"_at_MalwareTechBlog" to prevent the WannaCry from spreading.
