SQL injection attacks jumped 69% in Q2

My website monitors were going off the charts one day and I started investigating. Tons of SQL Injection attempts were flooding my servers. Without much difficulty, I tracked the IPs to a company that does security checking and reporting. I never requested such a test.

Later, that company sent me an email saying my site was insecure because they sent a SQL injection request and the response included lots of SQL. They wanted to sell me a comprehensive report and methodology to eliminate similar threats in the future.

Turns out, the SQL their threat detection system found was in a static html blog post where I was telling people how to build a particular type of SQL Statement. I did not purchase the "services" they were selling.

I wonder, and I am just pulling this out of my ass, if this is anything like the Skyscraper Index.

Perhaps we see this many SQL Injections because money is getting thrown around too liberally (and bad coders are getting more work) and is a precursor to a bubble.

Does anyone know how this news correlates with past SQL injection numbers, and if it has increased relative to the amount of internet usage?
