Zhang, an electrical engineer in Boston, decided to post about trying to unlock his Justice Tech Solutions Securebook 5 on the social platform X. The thread went viral — also catching the attention of Washington corrections officials, who have used the device for college programming since 2020.

Of particular concern was an article about Zhang’s thread published on a hacker website that shared the default password for the underlying software that starts the laptop’s operating system, presenting what the Department of Corrections considered a security concern.

The department then announced Thursday, five days after Zhang’s viral post, that it would collect all secure laptops from incarcerated students statewide “to provide an immediate system update.” By Saturday, corrections staff had collected around 1,200 laptops, spokesperson Chris Wright said in an email.

Wright confirmed no one incarcerated in Washington prisons had attempted to unlock their devices but said the decision was “made out of an abundance of caution.” It wasn’t immediately clear whether other states whose corrections departments use Securebook 5 laptops have also pulled the devices.
