What leaked

UnspecifiedJob applicant information

Who is affected

  • Job applicants (part-time)

Cause

Unauthorized access by a third party to the recruitment management platform provided by ApplyNow Inc., the contractor for part-time job interview operations

Timeline

  1. First disclosure
  2. Company issued an update

Response

  • Blocked the entry point
  • Vendor review
  • Governance / committee

Strengthening security and information management in cooperation with the contractor

What you should do

  1. Expect targeted phishing posing as HR or interview contacts
  2. Check the company's notice to see if you're affected

Lessons for companies

  1. Inventory internal tools (BI, CMS) as exposed assets. 'Internal only' is not a defense
  2. Put security requirements, audit rights and reporting deadlines in vendor contracts
  3. Report to the PPC: preliminary in 3–5 days, final in 30 (60 if malicious)
  4. Run red teaming and AI-assisted hardening, and publish how much you invest
