This means it won't propagate unless someone is so foolish as to ignore their antivirus messages and click on the attachment.
But Wanna Decryptor doesn't need to do this—it uses the magic NSA code in ETERNALBLUE to scan the internet for targets.
over the Internet), at least three servers are necessary: Active Directory, Front End Server and Access Edge Server SIP trunks allow for PSTN access by configuring Lync to pass all inbound and outbound phone calls over the internet without any telephony equipment.
They usually take 7 to 14 days to be ordered/provisioned.
Someone unknown—as noted, this novel is short on identifiable people the reader can relate to—takes the code for a piece of ransomware usually distributed as an email attachment, and turns it into a payload for ETERNALBLUE, which is a worm—capable of directly infecting other machines on the same network without human intervention.
And in a matter of hours, the new malware, known as Wanna Decryptor, infects the entire British National Health Service, a Spanish cellphone company, Fed Ex, and over a third of a million computers whose owners had lazily failed to enable automatic security updates from Microsoft.
Also, the characterisation is spotty: the shadowy villain remains off-screen for the entire novel (and apparently gets away with their crime), the hero who saves the day only appears in the last chapter, and the overall lack of thematic resolution at the end of the novel is painful.It's a worm—a boringly old-hat idea first introduced into fiction by SF author John Brunner in his 1977 novel "The Shockwave Rider". In the foreground, ambulance despatch systems are going down: clinical information systems are offline: hospitals are declaring major incidents and trying to revert to paper and pen: operations are cancelled except in case of life-threatening emergencies because doctors can't review X-rays and medical records: the entire Telefonica cellphone network stops being able to handle billing and orders in Spain: Fed Ex's parcel network is inaccessible: Deutsche Bahn train signaling is disrupted across half of Europe ...(To this extent, the plot of "Zero Day" isn't even original.) One is supposed to believe that evil genius hackers (unidentified) using code stolen from the most secretive of espionage organizations by some third party (also unidentified) and released for free on the internet, took someone else's poor quality malware (author unidentified) and turned it into a cyber first-strike weapon that causes carnage worldwide because millions of responsible computer operators fail to apply vital software security patches for months after they're released? And a mild-mannered British computer security expert ?However, instead of helping Microsoft fix them, we are supposed to believe that the NSA their knowledge of weaknesses in Microsoft Windows, a vitally important piece of their own nation's infrastructure, in case they'll come in handy againt some hypothetical future enemy.(I'm sorry, but this just won't wash; surely the good guys would prioritize protecting their own corporate infrastructure?
