马里兰大学的一项研究表明，平均每39秒有一次黑客攻击。这是2007年发表的数据，一直被网络安全界引用至今。https://www.cybintsolutions.com/cyber-security-facts-stats/

2019年网络受到黑客攻击基本事实如下：

• There is a hacker attack every 39 seconds

• Russian hackers are the fastest

• 300,000 new malware is created every day

• Multi-factor authentication and encryption are the biggest hacker obstacles

• You can become an American citizen for $6000

• The cost of data breaches will increase to $2.1 trillion globally in 2019

• The cybersecurity budget in the US is $14.98 billion

  另外有一个数据表明这种ransomeware每隔14秒攻击1个企业。

马云说阿里巴巴每天受到3亿黑客攻击，就是300000000/24/60/60=3472次/每秒。

商人可以信口开河，科学家研究人员千万不要。
