The Australian Cyber Security Centre (ACSC) has issued a joint advisory warning that Russian state-supported hackers are running a targeted phishing campaign against organisations using a popular business email and collaboration platform. While the specific software named in the advisory, Zimbra Collaboration Suite, may not be what your business runs day to day, the tactics behind this attack are exactly the same ones being used right now against Microsoft 365, Google Workspace, and every other email system small businesses rely on across Gippsland and regional Victoria.
This is a timely reminder that phishing attacks are no longer just clumsy, poorly-written emails asking you to click a suspicious link. Government advisories like this one show that well-resourced, state-backed groups are actively refining how they trick people into handing over their login credentials, and small businesses are very much in the blast radius even if they are not the direct target.
According to the advisory, the group known as LAUNDRY BEAR has been running a phishing campaign specifically designed to compromise accounts on Zimbra Collaboration Suite, a web-based email and collaboration platform used by government agencies, businesses, and other organisations worldwide. The attackers craft convincing emails that trick users into entering their login details on a fake page, or that exploit weaknesses in how the platform handles authentication.
Once inside a mailbox, attackers with state backing typically aren’t just after a quick scam. They are looking for sensitive correspondence, financial information, client data, and a foothold they can use to move further into an organisation’s systems or impersonate staff to attack other businesses and contacts.
It’s tempting to read an advisory like this and think “we don’t use that software, so it doesn’t apply to us.” That would be a mistake. The real story here is the method, not the specific product. Phishing remains the single most common way small businesses get compromised, and state-sponsored groups are the ones setting the standard for how convincing these attacks have become.
Techniques refined against large platforms and government targets have a habit of trickling down into the tools used by everyday cybercriminals within months. The fake login pages, the urgency-driven email wording, and the exploitation of trust in familiar business tools are all reusable against any small business using cloud email, regardless of which provider you’re with.
For a regional business, a compromised email account isn’t just an inconvenience. It can mean:
Unlike a large enterprise with a dedicated security team, most small businesses don’t discover this kind of compromise for weeks, if at all, because nobody is watching the logs.
This is the single most effective defence against exactly this type of attack. Even if an employee’s password is stolen through a convincing fake login page, MFA means the attacker still can’t get in without a second code or approval from the employee’s phone. If your business email, banking, or cloud accounting software doesn’t have MFA switched on right now, that should be your first priority this week.
Phishing emails increasingly look legitimate, often mimicking real login pages down to the logo and layout. Staff should be encouraged to:
Whether it’s your email platform, your accounting software, or your point-of-sale system, security patches exist because vulnerabilities are found and exploited. Advisories like this one from the ACSC often relate to specific technical weaknesses that get patched once discovered, so staying current on updates closes doors attackers rely on.
Most cloud email platforms, including Microsoft 365 and Google Workspace, offer login activity logs and can alert you to sign-ins from unusual locations or devices. Ask your IT provider to make sure these alerts are switched on and that someone is actually watching them.
If an account is compromised, knowing exactly what to do, who to call, and how quickly you can lock things down makes an enormous difference to the outcome. Businesses that have thought this through in advance recover far faster than those scrambling for the first time during an actual incident.
Advisories like this one are a useful early warning system precisely because they come from government cyber security agencies tracking sophisticated, well-funded threat actors. As reported by the Australian Cyber Security Centre, the tactics used against Zimbra users reflect a broader pattern of state-backed groups targeting business email systems generally, and small businesses in regional areas are not exempt simply because of their size or location.
Cybercriminals, both state-backed and opportunistic, increasingly see small and medium businesses as easier targets than large enterprises with dedicated security teams. Taking the practical steps above doesn’t require a big budget or a technical background, just a willingness to prioritise a handful of straightforward changes that make your business a much harder target.
