high severity December 07, 2023 · 3 min read Unverified claim — what this is

signiflow.com Listed by lockbit3 Ransomware Group

If you are a customer of signiflow.com, here’s what is being claimed, and what it would mean for you.

signiflow.com was listed on LockBit's leak site. LockBit claims to have stolen internal data. This is the group's claim, not a confirmed finding.

signiflow.com Listed by lockbit3 Ransomware Group

On December 07, 2023, the ransomware group LockBit3 added signiflow.com to its public leak site, claiming that it had exfiltrated internal files during a ransomware attack on the South African digital-signature company founded in 2013.

You can’t unleak data. You can take away what it’s worth.
A leaked record is where it starts, not where it ends. What turns it into your front door is the look-up sites publishing your address beside your name — and those are what an AI reads when somebody asks about you. The free scan shows you both. We write to 582 companies.

Primary Disclosure Details

The LockBit3 leak-site listing states that attackers obtained internal files from SigniFlow, including client-related documents and contracts. The notification does not quantify how many records were taken or name specific data fields. It simply declares that the company’s files have been downloaded and will be published if a ransom is not paid. The listing does not detail the initial access vector, the precise date of encryption, or any proof-of-compromise samples beyond the claim of successful exfiltration. Public reporting on LockBit3 indicates the group typically posts a countdown timer once data is staged for release.

Why This Matters for You and Your Family

If you or anyone in your household has used SigniFlow to sign contracts, loan agreements, employment offers, or any other legally binding document, your personal or financial information may now sit inside the stolen archive. Even though the exact number of affected individuals remains unknown, the exposure of client files and contracts creates immediate risk for identity theft, loan fraud, and targeted phishing. Families who relied on the platform for remote closings, estate planning, or small-business paperwork are now left wondering whose names, addresses, identification numbers, and signatures are circulating in criminal channels.

Doxxing and Identity-Chain Risks

Ransomware leaks rarely stop at one company. A single exposed contract can link your email address, phone number, physical address, and employer. Attackers then cross-reference those details against other breaches to build a complete profile. This chaining turns an isolated incident into long-term doxxing fuel: criminals can impersonate you to open accounts, file fraudulent tax returns, or harass family members. Credential leaks that often accompany ransomware also cascade into gaming-account takeovers when the same password protects a child’s Roblox, Fortnite, or Steam profile. Once one handle is linked to a real identity, the entire household becomes easier to target.

LockBit3’s Known Track Record

Public reporting attributes LockBit3 as the current iteration of the LockBit ransomware operation, which first appeared in 2019 and rebranded after law-enforcement pressure. The group has claimed responsibility for attacks on hundreds of organizations worldwide, including healthcare providers, manufacturers, and professional-services firms. Its typical playbook involves stealthy initial access through compromised remote-desktop credentials or vulnerable web applications, followed by rapid exfiltration of sensitive folders before encryption. LockBit3 then demands payment in Bitcoin and uses dual extortion: threatening both data publication and DDoS attacks. The leak site functions as both a shaming platform and a sales portal for stolen data when victims refuse to pay.

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.
  • Rotate any password you ever used on signiflow.com wherever it has been reused, and switch to 2FA through an authenticator app instead of SMS.
  • Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next exposure surfaces in hours rather than months.
  • Cover the household with DoxxScan family protection that extends to dependents and children’s gaming accounts that often chain back to the same credentials and address.
  • Let remediation specialists handle ongoing takedown requests for any exposed contracts or personal documents appearing on data-broker and underground sites.

The SigniFlow breach is a reminder that even routine digital-signature tools can become high-value targets when they hold legally binding records. Staying ahead requires more than changing one password; it demands visibility into how your information travels across the internet. DoxxScan by GalaxyWarden delivers that visibility through continuous monitoring, AI-powered identity-chain mapping, and hands-on remediation by specialists who work directly with your household, including children’s gaming accounts.

Unverified claim — what this report is
This page documents a public listing on a ransomware/extortion group’s leak site, tracked via public threat-intelligence sources. A listing is the attacker’s claim. GalaxyWarden aggregates and reports such claims; we have not independently verified that a breach occurred, what data (if any) was taken, or the accuracy of anything the group asserts, and the named organisation has not necessarily confirmed the incident. Sections above describe what the listing shows and the group’s documented history — not verified findings about the named organisation. If you represent this organisation and believe anything here is inaccurate, tell us and we’ll review it promptly.
