MADISON, WI (WTAQ) - There's no way of knowing how many Wisconsinites could be affected by the Heartbleed Bug.
If nothing else, it's got lots of folks changing their passwords on things like their e-mail and online bank accounts.
The state's largest homegrown bank, Associated, told its online customers that its systems did not reveal any susceptibility to the encryption flaw. Other firms are alerting their customers about the status of their software systems.
Many institutions have moved quickly to patch their codes over the last week. But Nick Davis of UW-Madison says companies that don't respond could be leaving their users' sensitive data at risk.
The Heartbleed Bug affects encrypted data on sites with "HTTPS" in their addresses.
Experts say the bug's been around for up to three years -- but now that it's gotten heavy publicity, hackers might jump in.
Davis says there's no real evidence that the security hole has been exploited. Still, he says this is a good example of why you should change your passwords every month or so.
Associated Bank advises its customers to use passwords which are unique to other ones they have.
Davis says it's also a good idea to check your online financial accounts daily for unusual activity.
