Breach

Infiltration of PowerSchool's PowerSource customer support portal via stolen credentials enabled threat actors to access a maintenance access tool enabling entry to SIS instances and the eventual exfiltration of data such as names and addresses, as well as personally identifiable information, Social Security numbers, medical details, and grades, according to PowerSchool.

Nearly 6,500 of the impacted individuals were the company's employees, who had their names, birthdates, email addresses, taxpayer ID numbers, and HQ system account details, stolen as a result of the attack, according to Casio.

Infiltration of the third-party-managed Pro Shop website from Sep. 23 and 24 and Oct. 3 to 23 enabled the exfiltration of individuals' names, email addresses, and billing and shipping addresses, as well as their credit card types, numbers, verification numbers, and expiry dates, said Green Bay Packers in a data breach notice.

Aside from failing to address cybersecurity vulnerabilities in its systems that could have prevented the sweeping data breach, T-Mobile also improperly informed impacted individuals regarding the extent of the incident, according to Washington State Attorney General Bob Ferguson.

Infiltration of PSA's payroll records through the exploitation of a flaw in the systems of its payroll processor Banco Nacion also enabled yet-to-be-identified attackers to conduct fraudulent salary deductions ranging from $100 to $245, local media outlets reported.

Included in the stolen data trove were individuals' names, birthdates, gender, phone numbers, email addresses, addresses, education details, and employment information.

Infiltration of the hospital's network earlier that month resulted in the compromise of files, one of which had individuals' names, birthdates, Social Security numbers, state ID or driver's license numbers, biometric details, financial account data, payment card information, medical data, health insurance policy details, and user credentials, reported investigators.

"Atos understands that external third-party infrastructure, unconnected to Atos, has been compromised by the group Space Bears. This infrastructure contained data mentioning the Atos company name, but is not managed nor secured by Atos," said the firm in a statement.
