Computer crime has risen 33% in the past year, according to figures from the US-based Internet Crime Complaint Centre.
The centre is a partnership between the Federal Bureau of Investigation (FBI) and the National White Collar Crime Centre. It said crime rates had jumped between 2007 and 2008.
It received 275,284 complaints in 2008, up from 206,884 in 2007, the Telegraph reported.
The jump reflects the increasingly sophisticated methods of hackers taking advantage of ever-growing amounts of personal and financial data stored on the web.
The most common type of crime complaint was the non-delivery of merchandise or payment. But complaints ranged from credit card fraud to spam to child pornography.
The average individual loss in the US from computer crime was $931 last year.
