Guido Listed by akira Ransomware Group

On August 2, 2023, privately held commercial construction and building materials company Guido Companies appeared on the leak site of the Akira ransomware group. The listing states that attackers exfiltrated 115 GB of the firm’s corporate data, including files from HR, accounting, and financial systems. The notification does not specify how many individuals are affected or list exact record counts.

You can’t unleak data. You can take away what it’s worth.
A leaked record is where it starts, not where it ends. What turns it into your front door is the look-up sites publishing your address beside your name — and those are what an AI reads when somebody asks about you. The free scan shows you both. We write to 582 companies.

Details from the Leak-Site Listing

The Akira leak page, archived via ransomware.live, claims the data was taken during a ransomware attack and includes samples described as internal files. It does not detail the precise data types beyond broad categories of HR, accounting, and financial records, nor does it provide a full victim count. The posting encourages visitors to “check soon,” a common signal that the group may release additional samples or begin broader extortion. Public reporting on Akira indicates the group typically posts proof-of-exfiltration after initial ransom demands go unmet.

Why This Matters for You and Your Family

When a company like Guido handles payroll, employee benefits, vendor payments, or client contracts, your personal information often sits inside those HR and accounting systems. A leak of this size can expose names, addresses, Social Security numbers, bank routing details, or salary records. Even if you never worked directly for Guido, your data may appear if you were a customer, subcontractor, or dependent on an employee’s health plan. Once exposed, this information fuels identity theft, tax fraud, and targeted phishing that can reach you or your family at home.

115 GB of exfiltrated corporate files represents a substantial cache that attackers can mine for months. The disclosure indicates the breach occurred before the August 2 listing, but the exact intrusion date remains unknown.

The Doxxing and Identity-Chain Risk

Files from HR and accounting systems frequently contain spreadsheets that link employee names to home addresses, phone numbers, dates of birth, and sometimes spouse or child information. Attackers combine these details with usernames or email addresses found in the same archive, creating long identity chains. A single leaked work email can lead to personal accounts, especially when passwords are reused. For families, the risk extends to children whose information appears on dependent forms or emergency contacts. These chains often surface on dark-web forums and can cascade into account takeovers on social media, gaming platforms, or financial services.

Akira Ransomware Group’s Known Track Record

Public reporting attributes the emergence of Akira to early 2023. The group has targeted organizations across multiple sectors, often listing victims on its dedicated leak site after double-extortion attempts. Their typical playbook involves initial access through compromised remote desktop credentials or phishing, followed by exfiltration of sensitive files before deploying ransomware. Akira then demands payment to prevent data publication, using the leak site as leverage. The Guido listing fits this pattern, though the specific initial access vector for this incident has not been disclosed.

What to do

  • Run a DoxxScan to map every link between your handles, emails, phone numbers, and real identity, with cleanup handled by specialists.
  • Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next exposure is caught in hours rather than months.
  • Rotate any password you used at Guido or related vendor systems and switch to 2FA through an authenticator app instead of text messages.
  • Cover the household with DoxxScan family protection that extends to dependents and children’s gaming accounts, which often chain back to the same leaked address or parent email.
  • Let remediation specialists manage takedown requests for any exposed personal documents found on data broker sites or forums.

The Guido breach is a reminder that construction and building-material firms hold surprisingly personal data on ordinary families. Staying ahead requires more than checking one breach list; it demands ongoing visibility into how your information travels across the internet. DoxxScan by GalaxyWarden delivers that visibility through continuous monitoring across 13.1 billion+ breach records and over 100 platforms, AI-powered identity-chain mapping, hands-on remediation by specialists, and full household coverage that includes children’s gaming accounts vulnerable to credential-stuffing attacks that follow leaks like this one. Start your DoxxScan trial today to close the gaps before the next wave of extortion sites surfaces your data.

Unverified claim — what this report is
This page documents a public listing on a ransomware/extortion group’s leak site, tracked via public threat-intelligence sources. A listing is the attacker’s claim. GalaxyWarden aggregates and reports such claims; we have not independently verified that a breach occurred, what data (if any) was taken, or the accuracy of anything the group asserts, and the named organisation has not necessarily confirmed the incident. Sections above describe what the listing shows and the group’s documented history — not verified findings about the named organisation.
