Vulnerability in wireless networks exposed

A bug in wireless networks can leave the information you send at risk, according to the Federal Trade Commission.

“KRACK” allows attackers to break the encryption protecting most wireless networks, the FTC says.

While the vulnerability is not cause for panic—software companies have already begun rolling out security patches—it serves as an important reminder that nothing is 100-percent safe online.

“In order to be a victim of this attack, the user needs to be a direct target,” says Camilo Ruiz, a network security analyst at Dupaco’s Hillcrest Road branch in Dubuque, Iowa. “The attacker would have to be within range of the wireless signal between the user’s device and the wireless access point.”

Tips to help secure your information online

To reduce your chance of fraud with this vulnerability and others that are sure to follow, continue doing your part to secure your information online:

  • Keep your software and devices equipped with the latest security updates.
  • Join Wi-Fi networks that are private and protected, and avoid public networks. 
  • If you must use a public network, don’t send or access sensitive information. 
  • Before sending sensitive information, make sure the web address you are using begins with “https,” like /. “All connections to a https site are not affected by this vulnerability,” Ruiz says. 
  • Do not open attachments in emails from people you do not know or in messages that look suspicious.
  • Do not send private information—including your Social Security Number, credit and debit card numbers, and usernames and passwords—to people you don’t know.
  • Use a backup system that it is not connected to the device all the time.
