The Rialto Unified School District announced it has suspended online learning while it investigates a recent malware attack on the district’s computer system.

“Rialto Unified School District has been affected by malware, which is software that is specifically designed to disrupt, damage, or gain unauthorized access to a computer system,” the district stated in an announcement on its website Sunday.

Online classes will be suspended for all students and staff indefinitely while the district looks into the “nature and scope” of the attack.

“We understand that this news is difficult in these already challenging times and we appreciate your patience while we work to address this issue,” a portion of the statement read.

A spokesperson for the district met with the media Monday morning.

“We are working very hard. Our information technology department has been working day and night,” RUSD Communications Director Syeda Jafri said.

Any students with devices connected to the district’s server should not use them, Jafri said.

 It was unclear if any data had been compromised in the attack.
