If you are a customer of restargp.com, here’s what is being claimed, and what it would mean for you.

Restar Holdings Corporation operates as an electronics trading company in Japan and internationally. The company offers semiconductor and electronic components, system engineering, and reliability test services; and electronic and measuring equipment...

— from LockBit’s own leak-site posting. This is the group’s claim, quoted verbatim; it is not GalaxyWarden’s reporting and has not been independently verified.

On December 05, 2023, Restar Holdings Corporation, a Japanese electronics trading company, appeared on the LockBit 3.0 ransomware leak site. The listing states that internal files were exfiltrated during a ransomware attack. The number of records affected remains unknown, and the precise data types have not been detailed beyond the generic description of internal files.

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.

Primary Disclosure Details

The LockBit 3.0 leak site entry states that Restar Holdings Corporation suffered a ransomware intrusion in which attackers copied internal files before encrypting systems. No specific volume of data or list of exposed record types is provided in the posting. The disclosure does not include a public ransom demand figure or a firm negotiation deadline, which is consistent with many LockBit 3.0 listings that rely on private extortion pressure rather than immediate full data dumps. Public mirrors of the onion-site posting, such as those hosted on ransomware.live, preserve the original claim without additional evidence files at the time of first publication.

Why This Matters for You and Your Family

When a company that handles electronics components, semiconductor supply chains, or system engineering services is breached, the ripple effects often reach ordinary customers and partners. Your contact details, order history, or payment records could sit inside the “internal files” category even if the leak site does not spell that out. Any exposed business email or phone number tied to Restar can be used to launch targeted phishing or account takeover attempts against you personally. Families who have purchased electronics through distributors linked to Restar may find themselves one step closer to identity theft if those records surface in follow-on sales on criminal forums.

Doxxing and Identity-Chain Risks

Ransomware operators rarely stop at the first company they hit. A single leaked internal spreadsheet can contain employee names, personal email addresses, phone numbers, and sometimes home addresses. These pieces quickly link with other breaches to form an identity chain. An attacker who obtains your work email from the Restar files can cross-reference it with credential leaks from retail sites, streaming services, or your children’s gaming accounts. The result is doxxing that escalates from nuisance spam to full identity compromise, including SIM-swapping attempts or fraudulent loan applications in your name. Credential reuse across personal and vendor accounts turns one corporate breach into a household threat.

LockBit 3.0 Track Record

Public reporting attributes LockBit 3.0 as the latest iteration of a ransomware family that first appeared in 2019 under the original LockBit name. The group rebranded to LockBit 2.0 in 2021 and then to LockBit 3.0 in early 2022 after releasing a new encryptor and leak-site design. Notable prior victims include numerous manufacturing, logistics, and technology firms across North America, Europe, and Asia. Their typical playbook begins with initial access gained through compromised remote desktop credentials or exploited vulnerabilities in external software, followed by rapid lateral movement, data exfiltration via custom tools, and then dual extortion: threatening both file encryption and public release of stolen documents. The group routinely pressures victims by contacting customers, partners, and journalists when negotiations stall.

What to do

  • Run a DoxxScan to map every link between your handles, emails, phone numbers, and real identity, then use the cleanup of Warden to remove what you can.
  • Rotate any password you ever used at restargp.com or with Restar Holdings anywhere it is reused, and switch on 2FA through an authenticator app rather than SMS.
  • Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next exposure that touches you or your family is caught in hours, not months.
  • Cover the household with DoxxScan family coverage that extends to dependents and children’s gaming accounts, which often chain back to the same address or parent email and become vectors for further doxxing.
  • Let remediation specialists handle takedown requests across data brokers and extortion sites for you while you focus on securing day-to-day accounts.

The Restar Holdings listing is a reminder that supply-chain vendors most people never think about can still expose personal information that attackers will happily exploit. One timely scan and a few password changes can break the chain before it reaches your front door. DoxxScan by GalaxyWarden delivers continuous monitoring across 13.1B+ breach records and 100+ platforms, AI-powered identity-chain mapping, hands-on remediation by specialists, and full household coverage that includes children’s gaming accounts. Start your DoxxScan trial today and treat this claimed breach as the last time your data gets sold in silence.

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. If you represent this organisation and believe anything here is inaccurate, tell us and we’ll review it promptly.
