Bogdan Frasco, LLP Listed by cicada3301 Ransomware Group

On September 15, 2024, Bogdan Frasco, LLP, a San Francisco-based tax and accounting firm, was listed on the leak site of the cicada3301 ransomware group. The listing states that internal files were exfiltrated during a ransomware attack. The firm serves small and medium-sized businesses as well as individual clients, meaning many ordinary taxpayers, freelancers, and small-business owners in the Bay Area may have had sensitive personal and financial information placed at risk.

Details from the Leak-Site Listing

The primary disclosure on the cicada3301 leak site states that internal files were exfiltrated in a ransomware incident. It does not specify the exact number of affected individuals, the volume of data taken, or the precise categories of records involved. A download link is provided on the onion site, but the listing itself gives no further breakdown of contents. The firm’s public description notes its focus on tax preparation, accounting services, and responsive client support from its office above the Montgomery Street BART station. As is typical with these listings, the group is using the publication of stolen data to pressure the victim into payment.

Why This Matters for You and Your Family

If you or anyone in your household has used Bogdan Frasco for tax returns, bookkeeping, payroll, or individual financial advice, your information may now sit in an attacker-controlled archive. Tax documents often contain Social Security numbers, addresses, income details, bank account information, and sometimes copies of driver’s licenses or passports. When such data leaves a professional office through a ransomware attack, it rarely stays contained. Families who trusted the firm with yearly filings or business records now face the concrete risk that their most sensitive identifiers are available to criminals who specialize in turning that information into fraud, identity theft, or further extortion.

The Doxxing and Identity-Chain Risks

Tax and accounting records create especially dangerous identity chains. A single leaked email or phone number can be cross-referenced with the names, addresses, and Social Security numbers that frequently appear in tax files. Attackers then link these to usernames on social media, gaming platforms, or shopping sites. The result is a complete profile that enables account takeovers, synthetic identity fraud, and persistent harassment. Credential leaks of this nature frequently cascade into gaming accounts belonging to you or your children, where stolen logins are sold or used to harvest additional personal details that tie back to the same household. DoxxScan by GalaxyWarden continuously monitors across 13.1B+ breach records and 100+ platforms with AI-powered identity-chain mapping that connects handles to real identities, while its specialists provide hands-on remediation and household coverage that includes children’s gaming accounts.

Cicada3301’s Known Track Record

Public reporting attributes the cicada3301 ransomware group with activity that emerged in 2023. The group has targeted organizations across multiple sectors, often listing professional-services firms, manufacturers, and healthcare providers on its leak site when negotiations fail. Its typical playbook involves initial access through phishing or exploited remote desktop services, followed by exfiltration of sensitive files before encryption. The extortion style combines data publication on an onion site with countdown timers and occasional direct contact to victims. While the precise success rate and ransom demands in this specific case remain unknown, the group’s pattern shows a willingness to release stolen data when payments are not made.

What to do

• Run a DoxxScan to map every link between your emails, phone numbers, usernames, and real-world identity so you can see exactly what this claimed breach connects to.
• Rotate any password you ever used at Bogdan Frasco anywhere it has been reused, and switch to 2FA through an authenticator app rather than text messages.
• Enable continuous DoxxScan monitoring so the next time your information surfaces on a leak site or dark-web marketplace it is caught within hours instead of months.
• Cover the entire household with DoxxScan family protection that extends to dependents and children’s gaming accounts that often chain back to the same address or parent credentials.
• Let remediation specialists handle data-broker takedown requests and opt-out processes that would otherwise consume months of your own time.

The exposure of tax and accounting data rarely ends with a single leak; it marks the beginning of a long-tail identity risk that can surface for years. Acting quickly on the exposure while maintaining ongoing visibility is the most practical defense available to ordinary families. Start your DoxxScan trial and let the service’s continuous monitoring and specialist support work for your household.
