If you're a customer of SunTrust Bank, be warned: You may have trouble accessing your accounts online today.

Bloomberg reports, the group claiming responsibility for a wave of recent attacks on bank websites is at it again this week. The group says SunTrust's website will be hit Wednesday, followed by Regions Bank on Thursday.

In fact, there were reports of customers unable to access SunTrust's e-banking website on Wednesday.

"We have seen increased online traffic today, and experienced intermittent service availability of some of our online functions," SunTrust spokesman Mike McCoy said in an email. He declined further comment, saying it's a security-related matter.

Capital One says its website was disrupted Tuesday, but it doesn't believe any account information or customers' personal information was exposed.

This follows the initial wave of attacks, which hit major banks including Bank of America, Wells Fargo and JPMorgan Chase. The attacks are known as denial of service, in which someone uses networks of infected computers to overload websites with traffic and crash them.

There haven't been any reports of the attacks thus far resulting in the loss of any money or customer data.
