The exclusively positive affair close this assail is that — y'all are hither — equally later on reading this easy-to-understandable awareness article, y'all would live so cautious that y'all tin lavatory salve yourself from WannaCry, equally good equally other similar cyber attacks inwards the future.

For those unaware, Ransomware is a figurer virus that unremarkably spreads via spam emails together with malicious download links; particularly designed to lock upwardly the files on a computer, until the victim pays the ransom demand, unremarkably $300-$500 inwards Bitcoins.

But what makes WannaCry so unique together with nasty is its mightiness to self-spread without fifty-fifty involve to click whatsoever link or a file.

The WannaCry ransomware, also known equally Wanna Decryptor, leverages a Windows SMB exploit, dubbed EternalBlue, that allows a remote hacker to hijack computers running on unpatched Microsoft Windows operating system.

Once infected, WannaCry also scans for other unpatched PCs connected to the same local network, equally good equally scans random hosts on the wider Internet, to spread itself quickly.

What Has Happened So Far

We convey been roofing this storey since Fri when this malware was firstly emerged together with striking several hospitals across the globe, eventually forcing them to unopen downward their entire information technology systems over the weekend, thus rejecting patients appointments, together with cancel operations.

Later this cyber assail brought downward many organizations to their knees.

Instead of repeating same details again, read our previous articles dig deeper together with know what has happened so far:

• Day 1: OutCry — WannaCry targeted over 90,000 computers inwards 99 countries.
• Day 2: The Patch Day — A safety researcher successfully constitute a way to deadening downward the infection rate, together with meanwhile, Microsoft releases emergency land updates for unsupported versions of Windows.
• Day 3: New Variants Arrives — Just yesterday, some novel variants of WannaCry, amongst together with without a kill-switch, were detected inwards the wild would live hard to halt for at to the lowest degree side past times side few weeks.

Isn’t the Cyber Attack Over?

Absolutely not.

This is only beginning. As I reported yesterday, safety researchers convey detected some novel versions of this ransomware, dubbed WannaCry 2.0, which couldn’t live stopped past times the kill switch.

What's fifty-fifty worse is that the novel WannaCry variant believed to live created past times someone else, together with non the hackers behind the firstly WannaCry ransomware.

It has been speculated that at nowadays other organized cybercriminal gangs, equally good equally script-kiddies tin lavatory larn motivated past times this incident to create together with spread similar malicious ransomware.

How to Protect Yourself from WannaCry Ransomware?

Here are some unproblematic tips y'all should ever follow because most figurer viruses brand their ways into your systems due to lack of unproblematic safety practices:

If y'all are using whatsoever version of Windows, except Windows 10, amongst SMB protocol enabled, brand certain your figurer should ever have updates automatically from the Microsoft, together with it’s up-to-date always.

2. Patch SMB Vulnerability

Since WannaCry has been exploiting a critical SMB remote code execution vulnerability (CVE-2017-0148) for which Microsoft has already released a land (MS17-010) inwards the calendar month of March, y'all are advised to ensure your scheme has installed those patches.

Moreover, Microsoft has been really generous to its users inwards this hard fourth dimension that the companionship has fifty-fifty released the SMB patches (download from here) for its unsupported versions of Windows equally well, including Windows XP, Vista, 8, Server 2003 together with 2008.

Note: If y'all are using Windows 10 Creators Update (1703), y'all are non vulnerable to SMB vulnerability.

3. Disable SMB

Even if y'all convey installed the patches, y'all are advised to disable Server Message Block version 1 (SMBv1) protocol, which is enabled past times default on Windows, to preclude against WannaCry ransomware attacks.

Here's the listing of unproblematic steps y'all tin lavatory follow to disable SMBv1:

1. Go to Windows' Control Panel together with opened upwardly 'Programs.'
2. Open 'Features' nether Programs together with click 'Turn Windows Features on together with off.'

6. Be Suspicious of Emails, Websites, together with Apps

Unlike WannaCry, most ransomware spread through phishing emails, malicious adverts on websites, together with third-party apps together with programs.

So, y'all should ever exercise caution when opening uninvited documents sent over an e-mail together with clicking on links within those documents unless verifying the source to safeguard against such ransomware infection.

While it's yet non known who is behind WannaCry, such large-scale cyber attacks are frequently propagated past times state states, but this ongoing assail does non comport whatsoever link to unusual governments.

"The recent assail is at an unprecedented score together with volition require a complex international investigation to position the culprits," said Europol, Europe's constabulary agency.

Why are they hijacking hundreds of thousands of computers or so the globe? Simple — to extort money past times blackmailing infected users.

By looking at the infection rate, it seems similar the criminals responsible for this absurd assail would convey made lots together with lots of dollars so far, but surprisingly they convey made relatively picayune inwards the way of profits, according to @actual_ransom, a Twitter describe of piece of job organisation human relationship that’s tweeting details of every unmarried transaction.

Who is responsible for WannaCry Attack?

— Is it Microsoft who created an operating scheme amongst so many vulnerabilities?

— Or is it the NSA, the intelligence way of the United States, who constitute this critical SMB vulnerability together with indirectly, facilitates WannaCry similar attacks past times non disclosing it to Microsoft?

— Or is it the Shadow Brokers, the hacking group, who managed to hack the NSA servers, but instead of reporting it to Microsoft, they decided to dump hacking tools together with zero-day exploits inwards public?

— Or is it the Windows users themselves, who did non install the patches on their systems or are yet using an unsupported version of Windows?

I do non know who tin lavatory live blamed for this attack, but according to me, all of them shares equal responsibility.

Microsoft Blames NSA/CIA for WannaCry Cyber Attack

Microsoft has striking out at the US regime for facilitating cyber attacks, similar WannaCry, past times non disclosing the software vulnerabilities to the respective vendors together with belongings them for their benefits, similar global cyber espionage.

In a spider web log post on Sunday, Microsoft President Brad Smith condemned the US intelligence agencies’ unethical practices, proverb that the "widespread damage" caused past times WannaCry happened due to the NSA, CIA together with other intelligence agencies for belongings zero-days together with allowing them to live stolen past times hackers.

"This is an emerging pattern inwards 2017. We convey seen vulnerabilities stored past times the CIA present upwardly on WikiLeaks, together with at nowadays this vulnerability stolen from the NSA has affected customers or so the world," Smith said.

This contention also publicly confirms that the hacking tools together with exploits leaked past times the Shadow Brokers belong to Equation Group, an elite grouping of hackers from NSA.

"Repeatedly, exploits inwards the hands of governments convey leaked into the populace domain together with caused widespread damage," Smith wrote.

Thank you. Stay tuned.
