What Happened
Southern California Telephone Company appeared on the Akira group's leak site on September 15, 2026, according to ransomware.live. The listing says the group "will upload 34gb of corporate data soon" and claims the data includes employee personal information such as passports and W-9s, customer information it describes as phone numbers and other sensitive information, contracts and agreements, NDAs and confidential certificates. It gives no date for the upload and no record count.
On the About page of its website, the company describes itself as a privately held competitive local exchange carrier and public utility, established in 1994 as Wholesale Airtime Inc. and headquartered in Southern California, that sells telephone and internet service to residential and business customers. Its website lists the company's address in Temecula, California.
Akira ransomware actors have hit businesses and critical infrastructure in North America, Europe and Australia since March 2023, according to a joint advisory from the FBI, CISA and international partners, last revised November 13, 2025. The advisory says the group uses a double extortion model, encrypting systems and threatening to leak sensitive information, and puts its ransomware proceeds at about $244.17 million as of late September 2025. The listing does not say whether any of Southern California Telephone Company's systems were encrypted.
What Was Exposed
Per ransomware.live, Akira leak-site listing for Southern California Telephone Company, September 15, 2026, the group claims to hold passports, W-9 forms, phone numbers, contracts, non-disclosure agreements and confidential certificates. No record count has been published.
If the listing is accurate, passports and W-9 forms together give an attacker an employee's identity document and taxpayer identification number, the core inputs for opening credit or filing a fraudulent tax return in that person's name. Customer phone numbers let a caller pose as the carrier and ask for account PINs or payment details.
What to Do If You Are Affected
The full sequence, and what to do in what order, is in what to do after a data breach.
What Is Not Known Yet
Akira's listing does not say how the group reached the company's systems, when any access began, or how many employees and customers the data covers. Whether the data has been uploaded yet, and whether Southern California Telephone Company will notify the people named in it, are open questions.
