kostika.co.il Listed by lockbit3 Ransomware Group

On February 02, 2023, Israeli construction firm Kostika.co.il appeared on the LockBit 3.0 ransomware leak site with 250 GB of internal files listed as exfiltrated. The disclosure indicates that data was stolen during a ransomware attack, although the exact number of people whose personal information is contained in those files remains unknown.

Primary Disclosure Details

The LockBit 3.0 leak page states that Kostika’s internal files were taken and gives the company until a set deadline to pay or face full publication. The listing does not detail the specific types of records inside the 250 GB archive, nor does it name individual victims or quantify how many customers, employees, or partners may be exposed. Public reporting on LockBit operations shows the group typically posts a sample of stolen data as proof before threatening to release the remainder.

February 02, 2023 marks the first public confirmation of the incident through the ransomware.live mirror of the official LockBit 3.0 site. The notification confirms the attack vector as ransomware with subsequent data exfiltration, a standard LockBit 3.0 pattern.

Why This Matters for You and Your Family

When a construction company like Kostika is breached, the stolen files often contain contracts, invoices, payment records, employee details, and client contact information. If your name, address, phone number, email, or banking details appear in those documents, the exposure can follow you for years. Families who hired Kostika for home renovations, commercial builds, or architectural work may find their private information now sitting in a ransomware repository.

250 GB of internal files represents decades of business records. Even without exact victim counts, the scale suggests broad exposure. Once data leaves a company’s control, it can be traded, sold, or used to launch follow-on attacks against you personally.

Doxxing and Identity-Chain Risks

Construction-industry breaches frequently create long identity chains. A single leaked invoice might link your home address to an email address, which in turn connects to social-media accounts or children’s gaming profiles. Attackers piece these fragments together to build a complete profile for identity theft, targeted phishing, or physical intimidation.

Credential leaks from such incidents routinely cascade into account takeovers. If you reused any password tied to Kostika correspondence, that credential can unlock email, banking, or gaming logins. Gaming accounts belonging to children are especially vulnerable because they often share the same household email or phone number listed in family contracts.

LockBit 3.0 Track Record

Public reporting attributes LockBit’s initial emergence to 2019, with version 3.0 appearing in early 2022. The group has hit hospitals, manufacturers, logistics firms, and professional-services companies worldwide. Their typical playbook begins with initial access through compromised remote-desktop credentials or phishing, followed by rapid lateral movement, data exfiltration, and then dual extortion: demanding ransom to decrypt systems and a second payment to prevent leak-site publication.

LockBit 3.0 is known for aggressive deadlines and for publishing data when victims refuse to pay. The group operates a leak site that updates in near real time, giving affected parties and the public direct visibility into what has been taken.

What to do

• Run a DoxxScan to map every link between your handles, emails, phone numbers, and real identity, with cleanup handled by specialists.
• Rotate any password you ever used in correspondence with Kostika or similar construction vendors, then enable 2FA through an authenticator app rather than SMS.
• Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next exposure surfaces in hours instead of months.
• Cover the entire household with DoxxScan family protection that extends to dependents and children’s gaming accounts sharing the same address or contact details.
• Let remediation specialists manage takedown requests for any personal records that surface on data-broker or extortion sites.
