sipicorp.com Listed by blackbasta Ransomware Group

On December 22, 2023, Sipi Corporation of Chicago appeared on the leak site operated by the Black Basta ransomware group. The listing states that attackers exfiltrated 145 GB of internal files from the metals refining and recycling company, including users’ personal folders, accounting records, corporate documents, and related materials. Anyone whose personal or employment data touched Sipi’s systems may now be exposed.

Details from the Leak Listing

The Black Basta leak page for sipicorp.com explicitly lists the victim’s address at 1720 N. Elston Avenue, Chicago, Illinois 60642-1579 and describes the stolen material as “Users personal folders, ACCOUNTING, Corporate documents and etc.” The disclosure does not quantify how many individuals are affected, nor does it itemize every file type beyond those broad categories. It states the data was taken during a ransomware attack and is now published for anyone to download.

145 GB of exfiltrated material is a substantial volume for a company of Sipi’s profile, indicating the attackers gained broad access to file servers rather than a single workstation.

Why This Matters for You and Your Family

When a company that employs people, pays vendors, or maintains customer records suffers a breach, the information stolen is rarely limited to corporate trivia. Personal folders often contain scanned IDs, tax forms, medical benefit details, or family contact lists. Accounting files can expose Social Security numbers, bank routing information, or payment histories tied to individuals. Once these records leave the company’s control, they become raw material for identity theft, tax fraud, or targeted phishing aimed at you or relatives who worked with or for Sipi.

Ordinary families rarely realize how many third-party vendors hold their data until a breach like this surfaces. The exposure is real even if your name never appears in a news headline.

Doxxing and Identity-Chain Risks

Leaked internal folders frequently contain spreadsheets that link employee names, email addresses, phone numbers, and sometimes home addresses. Attackers and opportunistic criminals combine these fragments with data from other breaches to build persistent identity chains. A username found in one document can be tested across gaming platforms, email accounts, and financial apps. Children’s accounts are especially vulnerable because parents often reuse credentials or store family information in shared folders that end up in the same exfiltration set.

Credential leaks of this nature routinely cascade into account takeovers on Steam, Roblox, Discord, and other services where kids maintain profiles tied to the same household email or phone number.

Black Basta’s Known Track Record

Public reporting attributes the first Black Basta ransomware activity to early 2022. The group has since hit hospitals, manufacturers, educational institutions, and professional services firms. Their typical playbook involves initial access through phishing or exploited remote desktop services, followed by deployment of ransomware that encrypts systems while quietly exfiltrating data beforehand. After encryption they demand payment for both decryption and non-disclosure; when unpaid they publish samples and eventually the full archive on their leak site. The sipicorp.com posting follows this exact pattern.

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 ever used at Sipi or related services, replace it with a unique passphrase, and secure the account with an authenticator app instead of SMS.
• Cover the household with DoxxScan family protection that extends to dependents and children’s gaming accounts that often chain back to the same address or parent email.
• Let remediation specialists handle ongoing takedown requests for any personal documents that surface on data-broker or extortion sites.

The exposure of 145 GB of Sipi’s internal files is a concrete reminder that your information is only as safe as the weakest vendor that holds it. Starting with a DoxxScan gives you visibility and hands-on remediation specialists who treat household and children’s accounts as part of the same identity chain. Continuous monitoring across breach repositories and dark-web platforms is the practical defense against the next Black Basta-style leak that has not yet been published.
