soshin.co.jp Listed by lockbit3 Ransomware Group

On April 21, 2023, Japanese electronics component manufacturer Soshin Electric appeared on the LockBit 3.0 ransomware leak site. The listing states that internal files were exfiltrated during a ransomware attack; the company has not published a public breach notification quantifying affected records or detailing the precise data types involved.

Primary Disclosure Details

The LockBit 3.0 leak page, still accessible via the onion link at the time of analysis, claims successful data theft from Soshin Electric’s network and threatens publication unless a ransom is paid. The disclosure does not specify the volume of data taken, the exact systems compromised, or name any customer or employee records. It simply lists the company alongside a countdown timer and sample screenshots of purported internal documents. Public reporting on LockBit 3.0 indicates the group typically posts proof-of-exfiltration samples to pressure victims, yet the exact contents listed for Soshin remain partially redacted on the mirror site hosted at ransomware.live.

Why This Matters for You and Your Family

Even when a breach notification does not list your name, suppliers like Soshin Electric often hold business-to-business records that include employee contact details, vendor contracts, and payment information from partner organizations. If you or a family member works at a company that buys capacitors, filters, or circuit components from Soshin, your workplace data may now sit in an attacker-controlled archive. Internal files exfiltrated can contain spreadsheets that link personal identifiers across suppliers, turning a corporate incident into a personal exposure overnight.

Doxxing and Identity-Chain Risks

Ransomware groups rarely stop at encryption; they exfiltrate data precisely because stolen documents create leverage for extortion and downstream identity crimes. A leaked internal file that pairs an employee’s work email with a personal phone number or home address becomes the first link in a doxxing chain. Attackers or opportunistic criminals can then correlate that information with credential leaks from other sources, gaming accounts, or social-media handles. Once the chain is built, it is trivial to impersonate victims, file fraudulent tax returns, or target family members. Credential leaks like this one frequently cascade into account takeovers precisely because employees reuse passwords between corporate systems and personal services, including children’s gaming accounts that often share the same household email domain.

LockBit 3.0 Track Record

Public reporting attributes the LockBit 3.0 variant to a ransomware-as-a-service operation that first appeared in early 2020 under the original LockBit name. The group rebranded to LockBit 3.0 in 2022 after law-enforcement pressure and has since claimed responsibility for attacks on hundreds of organizations worldwide, including healthcare providers, manufacturers, and local governments. Their typical playbook begins with initial access via compromised remote-desktop credentials or phishing, followed by lateral movement, data exfiltration, and then dual extortion: demanding ransom for both decryption keys and non-disclosure of the stolen files. The Soshin Electric listing follows this pattern exactly.

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.
• Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next exposure surfaces in hours rather than months.
• Rotate any password you have ever used at Soshin Electric or its partner portals anywhere it is reused, and switch to 2FA via an authenticator app instead of SMS.
• Cover the household with DoxxScan family coverage that extends to dependents and children’s gaming accounts that often chain back to the same address or email.

The Soshin Electric breach is a reminder that supply-chain vendors you have never heard of can still expose your family’s information. Start your DoxxScan trial today; its continuous monitoring, AI-powered identity-chain mapping, hands-on remediation by specialists, and household coverage give ordinary families the same early-warning advantage once reserved for large corporations. DoxxScan is also effective for protecting gaming accounts because credential leaks like this one routinely cascade into account takeovers and doxxing chains that begin with a single supplier spreadsheet.
