Melbourne Financial Firm 3P Corporation Hit by Space Bears Ransomware: What Australian SMBs Must Do Now

A boutique Melbourne financial services firm is the latest Australian business to be hit by ransomware, with the Space Bears gang publishing more than 213 gigabytes of stolen client data — including full bank account details and signed tax documents — after a ransom deadline passed this week. Here's what happened and how your business can avoid the same fate.

What Happened at 3P Corporation?

On 10 April 2026, the Space Bears ransomware gang listed 3P Corporation — a boutique financial services aggregate headquartered in Melbourne's finance district — as a victim on its darknet leak site. The threat actors claimed to have exfiltrated a database, financial documents, and personal information belonging to both employees and clients.

3P Corporation, founded in 2013 and offering accounting and tax services, financial planning, legal advice, and HR services, initially denied that any client data had been compromised. A company spokesperson told media that its systems had detected the intrusion before any data could leave the network.

That claim was quickly contradicted by the evidence. After the ransom deadline — set for approximately 18 April 2026 — passed without a payment, Space Bears followed through on their threat and published a 213.3-gigabyte compressed archive of stolen files.

What Data Was Stolen?

The published data is particularly sensitive given the nature of 3P Corporation's business. According to reporting by Cyber Daily and Accountants Daily, the leaked archive includes:

For the clients involved — many of whom are individuals and small businesses who trusted 3P with their most sensitive financial data — the exposure of bank details and signed forms creates an immediate risk of identity fraud and account takeover. If you have ever used 3P Corporation's services, you should contact your bank immediately and monitor your accounts for suspicious activity.

Who Are Space Bears?

Space Bears is a relatively new ransomware operation that first appeared in April 2024. Cybersecurity researchers believe the group is based in Russia, and it has moved quickly — claiming 71 victims across multiple countries in less than two years of operation.

Their playbook follows the now-standard double-extortion model: encrypt the victim's data AND exfiltrate it simultaneously, then threaten to publish everything unless a ransom is paid. This approach is devastatingly effective against organisations that believe their backups alone will save them — because even with a restored system, the stolen data is still out there.

3P Corporation is not the only Australian organisation Space Bears has targeted. Australian managed services provider (MSP) Vertel also confirmed a Space Bears ransomware attack in early 2026, highlighting the group's specific interest in Australian professional services firms with access to rich client data.

Why Australian Financial Services Firms Are Prime Targets

It's no accident that ransomware groups like Space Bears are zeroing in on accountants, financial planners, and legal firms. These businesses hold a perfect combination of attributes that make them highly attractive targets:

Rich, Monetisable Data

Financial services firms hold bank account details, tax file numbers, signed legal documents, and business financial records. This data has significant value both as a ransom lever and on dark web marketplaces. A single tax return form can contain everything a criminal needs to commit identity fraud.

Often Under-Resourced for Cybersecurity

Many Australian SMBs — including financial advisory firms — operate lean teams focused on delivering client services rather than maintaining enterprise-grade IT security. They may lack dedicated security staff, rely on outdated software, or use weak password practices across the business. This makes them far easier to breach than large financial institutions with dedicated security operations centres.

Regulatory Pressure Creates Payment Incentives

Under Australia's Privacy Act and the Notifiable Data Breaches scheme, organisations must notify affected individuals and the Office of the Australian Information Commissioner (OAIC) when a data breach is likely to cause serious harm. The regulatory, reputational, and legal consequences of a disclosed breach can feel so severe that some businesses consider paying a ransom to prevent disclosure — exactly the outcome attackers are engineering.

How Ransomware Groups Get In: The Most Common Entry Points

Understanding how attackers like Space Bears gain initial access is the first step to stopping them. The most prevalent entry vectors in 2026 remain consistent:

Compromised Credentials

Weak, reused, or previously breached passwords are the number-one entry point for ransomware attacks. Once a threat actor has valid credentials for a Remote Desktop Protocol (RDP) connection, a VPN gateway, or a web application login, they can walk in the front door. Between January and March 2026, confirmed brute-force authentication attempts accounted for more than half (56%) of all confirmed ransomware-related incidents, according to Barracuda's SOC Threat Radar.

This is precisely why credential hygiene matters so much. Using a dedicated password manager like NordPass ensures that every account in your business uses a unique, complex password — so that a single breached credential can't cascade into a catastrophic network compromise. NordPass also monitors for leaked credentials across the dark web, alerting you when your email address or passwords appear in known breach databases.

Phishing and Social Engineering

A convincing phishing email targeting an accountant or financial adviser — perhaps posing as the ATO, a bank, or a software vendor — can deliver malware that establishes a foothold in the network. From there, attackers conduct reconnaissance over days or weeks before deploying ransomware.

Unpatched Vulnerabilities in Internet-Facing Systems

Exposed web applications, VPN appliances, and remote access tools with unpatched vulnerabilities are a persistent problem. In April 2026, CISA added a critical Apache ActiveMQ vulnerability (CVE-2026-34197) to its Known Exploited Vulnerabilities catalogue, joining a growing list of flaws in SonicWall and Fortinet devices actively targeted in the wild.

What Australian SMBs Should Do Right Now

The 3P Corporation incident is a wake-up call for every Australian accounting firm, financial planner, legal practice, and professional services business. Here are the immediate steps you should take:

1. Audit Your Passwords and Enable MFA Everywhere

Conduct a full audit of credentials used across your business — cloud services, accounting software, email, banking portals, and remote access tools. Eliminate password reuse immediately. Deploy a business-grade password manager such as NordPass for Business to generate and store unique credentials for every account. Then enable multi-factor authentication (MFA) on every system that supports it, prioritising anything with remote access.

2. Secure Your Website and Client Portals

If your firm operates a website with a client login portal, document submission feature, or any online form — and most do — that web presence is itself an attack surface. A web application firewall (WAF) intercepts malicious requests before they reach your server, and a website security platform like Sucuri provides continuous malware scanning, a cloud-based WAF, and DDoS protection. For financial services firms handling sensitive client submissions online, this layer of protection is essential, not optional.

3. Encrypt All Remote Connections with a VPN

If staff work remotely or connect to office systems from home, they must do so over an encrypted VPN connection. Unencrypted connections over public Wi-Fi or home networks can be intercepted, and if attackers capture credentials in transit the game is over. NordVPN offers business-grade encryption with a strict no-logs policy, protecting your team's connections wherever they work. For Australian businesses with staff in multiple states or remote locations, this is a practical, affordable safeguard.

4. Test and Verify Your Backups

Ransomware groups like Space Bears don't rely solely on encryption to pressure victims — they also steal the data. But having tested, air-gapped backups means that even if you can't or won't pay the ransom, you can restore operations quickly. Many SMBs discover during a ransomware incident that their backups were misconfigured or haven't been tested in years. Test your restoration process quarterly.

5. Report Incidents Immediately

If you suspect a breach, contact the Australian Cyber Security Centre (ACSC) at cyber.gov.au and the Office of the Australian Information Commissioner (OAIC) promptly. Under the Notifiable Data Breaches scheme, you are legally required to notify affected individuals if a breach is likely to cause serious harm. Early notification, even if uncomfortable, gives affected clients the chance to protect themselves — and demonstrates good faith to regulators.

The Broader Pattern: Australia's SMB Ransomware Crisis

3P Corporation's breach doesn't exist in isolation. In recent months, Australian businesses across multiple sectors have fallen victim to ransomware operators:

The Australian Signals Directorate's (ASD) annual Cyber Threat Report has consistently found that small and medium businesses are disproportionately targeted relative to their security investment. Ransomware groups understand this asymmetry and exploit it ruthlessly.

The question is no longer whether Australian SMBs will be targeted — they already are. The question is whether they have the basic defences in place to survive an attack, or whether they will become the next headline.
