‘Insider spoofing’ or faking the CEO’s email address to trick the CFO into transferring millions to criminal bank accounts is big business. 

According to the FBI, between October 2013 and August 2015, 7,066 US businesses have fallen prey to ‘business email compromise’, netting criminals an estimated $747m.

Non-US victims lost a further $51m over the period, with the FBI estimating a 270 percent increase in identified victims since January 2015, when it first released figures about the threat category.

The upgrade will not change the genuine state of the license. Non-Genuine Windows is not published by Microsoft. It is not properly licensed, or supported by Microsoft or a trusted partner. If a device was considered non-genuine or mislicensed prior to the upgrade, that device will continue to be considered non-genuine or mislicensed after the upgrade

Microsoft says that it’s changing a key detail in Windows 10 that could break some applications. Windows 7 identified itself to apps and services as Windows 6.1. Windows 8 internally is Windows 6.2. Windows 8.1 is Windows 6.3. With Windows 10, Microsoft will move the version number to match the marketing name of Windows.

How to Prevent Hacking.
1. You need to make sure your personal computer does not have viruses, trojans, keyloggers, etc.
2. Change your passwords often. Use a different password for each website you regularly log into, and make sure your passwords are long and intricate so that they’re harder to guess. It’s especially important to keep your banking and other financial accounts secure.
3. Delete emails from unknown sources. Never click on an emailed link that looks questionable.
4. Do not respond to pop-up windows.
5. Do not download from unknown sites or free printables, desktop wallpapers, music-streaming software. It’s a quick and easy way for hackers to infiltrate you system.
6. Do not install illegal copy or any free program.

The situation is

You have only IPv4.
You have SPF.
You have rDNS.

You still got this error because your mail server has only IPv4 address and IPv6 is enable but empty.  Most like happen to Server 2008 and later.

1. If you have IPv6, you have to create reverse DNS for your IPv6 mail server and include IPv6 in you SPF for your domain.
2. If you have only IPv4, you have to disable IPv6 from this microsoft site.
