What's Publicly Reported from Reporting

Public reporting indicates the company suffered a ransomware attack in which attackers gained access to internal documents. The exact number of people affected remains unknown. Available details show that the data consists of internal files rather than a structured database of customer records. The listing appeared on the group’s dark-web leak page on April 27, 2026, following the typical ransomware pattern of initial access, data theft, and subsequent extortion pressure.

Why This Matters for You and Your Family

When a training and certification provider that handles sensitive professional records is breached, anyone who has taken courses, obtained certifications, or shared employment details with them could have personal information exposed. This includes names, contact details, training histories, and possibly employer information. For ordinary families this means another vector for identity theft, phishing, or unwanted solicitations. Even if you do not recall signing up directly, contractors, former employers, or schools may have forwarded your information to Certified Information Security for compliance training.

Credential leaks like this one frequently cascade into account takeovers elsewhere because people reuse passwords across work, personal email, and family accounts.

The Doxxing and Identity-Chain Implications

Stolen internal files often contain spreadsheets, email exports, or training rosters that link names to addresses, phone numbers, and sometimes dates of birth. Attackers and subsequent data brokers can combine these fragments with information from other breaches to build a complete profile. Once a real identity is connected to usernames, gaming handles, or social-media accounts, the risk of doxxing grows. Children’s gaming accounts are especially vulnerable because parents frequently use the same email address or a shared family phone number for registration.

apt73’s Publicly Known Track Record

Public reporting attributes apt73 with emerging in late 2024 as a ransomware operation that combines double-extortion tactics with selective data leaks. The group has listed healthcare providers, training organizations, and small-to-medium businesses. Its typical playbook involves gaining initial access through phishing or exploited remote-desktop services, exfiltrating documents before encrypting systems, then posting samples on its leak site with a countdown for payment. If no ransom is paid, larger portions or all stolen files are released. The group’s exact size and location are unclear, but its leak site remains active and is tracked by ransomware-monitoring services.

What to do

  • Run a DoxxScan to map every link between your emails, phone numbers, handles, and real identity so you can see exactly what chains back to the Certified Information Security breach.
  • Rotate any password you ever used at certifiedinfosec.com or related training portals and enable 2FA through an authenticator app on every account where that password was reused.
  • Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next time your information surfaces you learn within hours rather than months.
  • Cover the household with DoxxScan family protection that extends to dependents and children’s gaming accounts that often share the same contact details used in professional training records.
  • Let remediation specialists handle takedown requests for any exposed personal documents or broker listings that appear after this incident.

The breach of Certified Information Security is a reminder that even organizations you trust with professional records can become links in a larger identity chain. Taking concrete steps now limits how far attackers can travel with the stolen data. DoxxScan by GalaxyWarden delivers continuous monitoring across 13.1 billion+ breach records and more than 100 platforms, AI-powered identity-chain mapping, hands-on remediation by specialists, and full household coverage that includes children’s gaming accounts.
