Main Points: Holiday Ransomware Attacks Spike: Australia & New Zealand Cybersecurity Alert
- 78% of organizations in Australia and New Zealand fell victim to ransomware attacks in the past year, making ANZ the third most targeted region worldwide, following Germany and the US.
- Despite 55% of ANZ organizations feeling “very prepared” for ransomware attacks, their recovery times are some of the slowest in the world.
- IT security staffing can drop by up to 50% during holiday periods, creating critical vulnerabilities that cybercriminals actively exploit.
- Ransomware attacks during holidays and weekends have become a strategic pattern, with 53% of US attacks happening during these vulnerable times.
- By implementing 24/7 monitoring, identity threat detection systems, and holiday-specific response plans, the risk of ransomware attacks during peak seasons can be significantly reduced.
Cybercriminals don’t take holidays—they take advantage of them. As the holiday season approaches, businesses in Australia and New Zealand are facing a growing ransomware threat that specifically targets times when defenses are usually weakened. The 2025 Ransomware Holiday Risk Report has uncovered alarming trends that organizations across the region need to address immediately.
Concerning Rise in Holiday Ransomware Attacks on Australian Companies
The figures are stark and worrying: 78% of organisations in Australia and New Zealand have reported ransomware attacks in the last year, making the region the third most targeted in the world, behind only Germany (89%) and the United States (81%). This is not random targeting, but a deliberate strategy by those posing a threat, who have identified the particular weaknesses of ANZ companies, especially during holiday periods when there are fewer security staff on duty.
The increasing disparity between perceived readiness and actual recovery capabilities is what makes this trend particularly alarming. Recent research shows that ANZ organisations consistently underestimate their vulnerability and the complexity of recovering from advanced ransomware attacks that specifically target identity systems, which are the linchpins of most corporate networks.
Why Ransomware Attacks Increase During the Holidays
The holiday season is a prime time for cybersecurity threats. Employees are often more focused on celebrating the holidays than following security protocols, making them more vulnerable to attacks. According to Chris Inglis, former U.S. National Cyber Director, attackers take advantage of this natural decrease in vigilance during the holiday season. He said, “Ransomware attacks are designed to hit businesses when they’re most vulnerable.”
It’s not just a matter of chance that these attacks are planned for specific times. Cybercriminals intentionally plan their attacks for times when there are fewer staff members on duty, the ability to detect the attack is diminished, and the organization’s attention is directed elsewhere. This planned approach increases both the chances of a successful attack and the potential ransom payment as companies scramble to get back to business before crucial business periods.
Security Gaps Caused by 50% Staff Reduction
“Companies may cut their staff by half or more during the holidays, making them susceptible to attacks that would usually be detected and neutralized during normal operations. This cut in staff creates significant vulnerabilities that advanced cybercriminals are specifically trained to spot and take advantage of.”
— 2025 Holiday Ransomware Threat Report
During the holiday season, there is often a significant decrease in the number of security personnel on duty. This can lead to multiple security vulnerabilities at once. With only half of the regular team available to monitor alerts, many warning signs can go undetected until the encryption process has already begun. The ability to respond to incidents is also compromised. The limited staff available may not be able to provide the comprehensive, coordinated response necessary to stop sophisticated attacks.
The lack of staff becomes even more concerning when we consider the ever-growing complexity of ransomware attacks. Nowadays, cybercriminals don’t just use encryption tools. They also conduct thorough research, set up persistent mechanisms, and meticulously plan their attacks to cause as much harm as possible. If there aren’t enough people to keep an eye on these early signs of an attack, companies miss out on crucial early warning signals.
Adding to the danger, many companies don’t update their security measures for holiday periods. Usual monitoring limits, alert review processes, and escalation procedures frequently stay the same even though there are fewer people to respond, creating a risky gap between threat detection and response abilities exactly when attackers are most active.
Longer Detection Times During Holidays
- Normal business day ransomware detection time: 4.5 hours on average
- Holiday detection time: Over 9 hours on average
- Attacks discovered after encryption begins: 76% (holidays) vs. 43% (normal business days)
- Time from initial access to full network encryption: 72 hours (this is decreasing every year)
- Time to encrypt critical systems: Often under 45 minutes from the start of the attack
Longer detection times mean more potential damage. Every extra hour gives attackers more chances to extract sensitive data, compromise more systems, and set up persistent access that makes recovery more difficult. The extra time to detect attacks during holidays basically gives cybercriminals a big advantage in a conflict that’s already not balanced.
Cybercriminals Take Advantage of Preoccupied IT Staff
The individuals behind ransomware attacks are extremely savvy. They have a deep understanding of how organizations work and they know that IT teams are often not as focused on security during holiday periods. People are generally more relaxed during these times and are more likely to overlook small irregularities or give the benefit of the doubt to activities that seem suspicious but aren’t definitively harmful. Cybercriminals take advantage of this by slowly ramping up their activities. They stay just under the radar, not doing anything that would cause immediate concern during regular operations.
ANZ’s Recovery Crisis: A Disturbing Reality
The most shocking revelation from the 2025 State of Ransomware Survey isn’t just that ANZ organizations are often targeted—it’s their lack of effective recovery when attacks happen. Despite the global cybersecurity community making substantial progress in detection and prevention, the recovery capabilities of Australian and New Zealand businesses have lagged behind, opening up a risky vulnerability that attackers are eager to take advantage of.
As digital operations become increasingly vital across various industries, the time allocated for recovery (RTOs) keeps decreasing. However, the actual time it takes to recover from ransomware attacks in the Australia and New Zealand region has increased over the past year. This widening gap between what is expected and what is actually happening poses significant risks to business continuity. These risks go way beyond the immediate technical impact of an attack.
These extended recovery periods come with a hefty price tag, as each additional day of downtime can cost ANZ businesses an average of $250,000 in direct expenses and lost income. This financial strain often forces businesses to make the risky choice of paying the ransom, even though security agencies strongly discourage this.
Just 9% of ANZ Organizations Bounce Back in 24 Hours
When it comes to bouncing back from a ransomware attack, the picture is not looking great for ANZ organizations. Although 86% of the businesses surveyed thought they could get their critical systems up and running within 24 hours of a ransomware attack, the reality was quite different. Just 9% actually managed to recover in this timeframe, which is one of the biggest gaps between expectations and reality in the global survey data. This gap shows that there is a worrying lack of understanding about how complicated it is to recover from a modern ransomware attack, especially when identity systems like Active Directory have been compromised.
Why ANZ Lags Behind in Global Recovery Rates
Geographical Location Real 24-Hour Recovery Rate Average Full Recovery Duration Anticipated Recovery Duration North America 27% 5.2 days <1 day Europe 23% 6.7 days 1-2 days Australia/NZ 9% 8.3 days <1 day Asia 14% 7.5 days 1-3 days The Risky Gap Between Confidence and Reality
The gap between confidence and ability is one of the most alarming findings in the latest research. Despite 55% of ANZ organizations claiming to be “very prepared” for ransomware incidents, their actual recovery performance shows a worrying disconnect. This misplaced confidence can lead to inadequate investment in recovery capabilities, incomplete backup strategies, and insufficient testing of restoration processes—all of which become painfully apparent during actual attacks.
With ransomware groups using more advanced tools and AI-driven methods, this discrepancy between what is expected and what is achieved could become even more expensive for organisations that underestimate the complexity of modern incident responses. This disconnect is especially noticeable during holiday attacks, when the reality of limited staff clashes with hopeful recovery plans that assume the entire team is available.
5 Quick Steps to Safeguard Your Business This Festive Season
Given that holiday seasons are periods of increased risk, it is essential that businesses put in place particular protective measures to counter the increased vulnerability and reduced staffing during these periods. The strategies listed below are the most effective immediate steps that security teams can take to minimize the risk of ransomware attacks during the holidays.
1. Set Up Around-the-Clock Surveillance
Constant surveillance is especially important during holiday seasons when internal security teams may be understaffed. Using managed detection and response (MDR) services or security operations center (SOC) solutions that offer 24/7 coverage guarantees that suspicious activities aren’t missed just because employees are on vacation. These services should be set up with holiday-specific alert limits that account for legitimate changes in network activity patterns while remaining sensitive to potential attack indicators.
2. Use AI for Threat Detection
AI and machine learning are especially useful for protection during the holidays because they can automatically detect unusual behaviors that could be ransomware. Unlike older tools that rely on signatures, AI can identify new attack patterns and strange system behaviors that are signs of the early stages of ransomware. These technologies are even more useful when there aren’t many human analysts available.
The best AI systems are set up to know the normal network and user behavior patterns long before the holiday season starts. This way, the systems can tell the difference between the usual increase in activity during the holidays and behaviors that could be harmful. Businesses should make sure these systems are completely trained and tested before the holiday season starts. This is especially important when there are fewer staff members around to help.
3. Develop Incident Response Plans for the Holidays
Typical incident response plans are based on the assumption that normal staffing levels are maintained and that key personnel are available. Businesses must have incident response plans specifically for the holidays that take into account lower staffing levels, possible delays in contacting critical decision-makers, and clear escalation routes when the main contacts cannot be reached. These holiday-specific plans should include pre-approved action limits that allow the staff who are available to take the necessary containment steps without having to wait for approvals that may be delayed during the holiday season.
4. Safeguard Your Identity Management Systems
Identity systems such as Active Directory, Entra ID (previously known as Azure AD), and Okta are prime targets for ransomware attacks during the holiday season. Hackers understand that infiltrating these systems gives them the access rights they need to spread ransomware throughout the entire network. Therefore, it’s crucial to prioritize additional monitoring and protection for these vital identity systems before the holiday season kicks off.
Highly sophisticated identity threat detection systems can spot abnormal login patterns, attempts to increase access rights, and changes to directories that are often the first signs of a large-scale ransomware attack. Recovering from breaches of identity systems is especially difficult and time-consuming, so preventing these initial breaches is key to keeping your systems secure over the holidays.
5. Set Up Offline Backup Procedures
Ransomware operators these days often aim for backup systems to make sure recovery is impossible without a ransom payment. Using air-gapped backup methods that are totally separate from production networks is an important way to protect against this. Before holidays, companies should check that their latest backups are safely stored offline and have been checked to make sure they can be restored, focusing especially on backups of identity systems, which will be crucial for complete recovery.
Key Weaknesses Cybercriminals Exploit During the Holiday Season
Knowing what specific strategies ransomware criminals prefer to use during the holiday season helps security teams put up focused defenses. By concentrating their defensive resources on these areas of high risk, companies can make the most of their security staff, who are often stretched thin during holiday periods.
Identity Systems: The Main Point of Attack
Identity systems are the most prized target for holiday attackers, with 67% of successful ransomware attacks involving compromised identity infrastructures such as Active Directory. By focusing on these systems, attackers gain the elevated privileges required to disable security controls, modify group policies, and spread ransomware payloads throughout the entire network. The complexity of modern identity systems, coupled with their essential role in enterprise operations, makes them both an appealing target and a challenge to secure effectively.
Highly skilled threat groups have created advanced methods with the express purpose of exploiting and maintaining access to identity systems. They often set up backdoor accounts and alter security settings to guarantee ongoing access, even if their initial breach is discovered. These changes can be extremely subtle and often go unnoticed during regular monitoring, making specialized identity threat detection tools a necessity for thorough protection.
Weaknesses in Remote Access Points and VPNs
As the number of employees working remotely increases during holiday seasons, remote access infrastructure becomes a bigger target for ransomware operators. Virtual Private Networks (VPNs), Remote Desktop Protocol (RDP) endpoints, and remote access tools are often the first points of access, especially when multi-factor authentication is not consistently used. To quickly identify any suspicious connection attempts during holiday seasons, organizations should use geo-fencing, restrict connection times, and enhance logging for all remote access.
Mistakes in Cloud Setup
The rapid shift to cloud services has led to new weaknesses that ransomware operators take advantage of during times of lowered guard. Cloud storage that isn’t set up correctly, too many permissions, and APIs that aren’t properly secured are all attractive targets that can provide the first step for complex attacks. As companies depend more and more on cloud services for vital operations, making sure these environments are set up correctly and monitored becomes crucial for stopping ransomware incidents during the holidays.
Developing a 365-day Ransomware Defense
Even though holiday seasons are high-risk periods, a successful defense against ransomware requires continuous preparation and skill development throughout the year. Organizations that put in place a robust ransomware defense program experience significantly lesser impacts even when they are successfully attacked, with 62% managing to avoid any operational disruption despite attempts at encryption.
Enhanced Identity Threat Detection Tools
Identity systems are often the primary target in modern ransomware attacks. Therefore, organizations should prioritize the implementation of specialized identity threat detection and response (ITDR) capabilities. This will help to build a robust ransomware resilience. These tools keep an eye on the slight changes to directory services, suspicious privilege escalations, and unusual authentication patterns that often come before major ransomware deployments. By identifying these early warning signs, organizations can interrupt attack sequences before encryption begins, significantly minimizing potential impacts.
Staff Education Beyond Simple Understanding
Typical security awareness training often does not adequately prepare staff for the complex social engineering tactics used by current ransomware operators. Successful ransomware resilience needs scenario-based training that imitates the real techniques used by threat actors, especially those targeting remote workers during holiday periods.
Such comprehensive training should cover mock-ups of targeted phishing attempts, voice phishing (vishing) scenarios, and bogus IT support calls that emulate the actual strategies used in recent attacks. By letting employees experience realistic attack scenarios in a safe environment, organizations can drastically enhance their capability to identify and report actual threats when they take place.
Throughout the year, organizations should regularly conduct simulations, particularly ones that reflect the unique risks of holiday periods when employees might be more distracted and security-fatigued than usual. Organizations that implement this kind of contextual, scenario-based training report a 47% increase in threat identification rates compared to those using standard awareness approaches.
Putting Your Recovery Plans to the Test
The discrepancy between the anticipated and real recovery times in organizations in Australia and New Zealand underscores the need to frequently put recovery capabilities to the test in real-world scenarios. By simulating holiday staffing levels with tabletop exercises, you can pinpoint process slowdowns and communication issues before they interfere with real incident response initiatives.
The best testing programs consist of complete restoration drills using offline backups, with a special emphasis on recovering identity systems that are essential for resuming normal operations. These drills should be carried out with little prior warning and with holiday staffing levels to realistically mimic the circumstances of a real recovery.
“The best-performing organizations during real ransomware incidents are always those that have routinely practiced their recovery procedures under realistic conditions. Recovery plans that are only theoretical rarely survive contact with the reality of a sophisticated ransomware attack.”
— Ransomware Risk Report for the Holidays 2025
Recovery testing should not be limited to technical restoration processes. It should also include business continuity elements such as alternative communication channels, decision-making frameworks when key personnel are unavailable, and procedures for operating critical systems in degraded modes while full recovery continues. This comprehensive approach ensures that organizations can maintain essential operations even during extended recovery periods.
The True Price of Holiday Ransomware Attacks
The economic damage of holiday ransomware attacks goes much further than any possible ransom payment. The lengthy recovery times that ANZ organizations undergo directly result in operational losses, with each day of system downtime costing an average of $250,000 in direct costs and lost revenue. These costs increase dramatically for attacks that happen during peak business times that often align with or immediately follow major holidays, potentially jeopardizing the survival of affected organizations.
In addition to the immediate financial losses, holiday ransomware attacks can cause long-term reputational harm, regulatory difficulties, and customer trust problems that can impact a company’s performance for years after an event. The burnout of IT staff who are forced to work during holidays to restore systems also poses serious retention problems, with 34% of companies reporting that key security personnel quit within six months of significant holiday incident response efforts. These total costs make ransomware resilience a necessary investment, not just a nice-to-have security upgrade.
Commonly Asked Questions
As organizations gear up for the holiday season, they often have particular queries regarding the threat of ransomware and the best ways to defend against it. The answers provided below cover the most frequently asked questions, using up-to-date threat intelligence and successful strategies used by organizations to protect themselves from holiday ransomware attacks.
What makes holiday periods a hotbed for ransomware attacks?
There are several factors that make holiday periods a prime time for ransomware attacks. For one, many organizations are operating with a skeleton crew, with IT and security staff significantly reduced. This can sometimes mean that monitoring capabilities are cut in half or more. This happens at a time when employees are more likely to let their guard down due to holiday distractions and changes in their normal work routine. On top of that, if an attack happens right before or during a critical business period, the pressure to get systems back up and running is even greater. This can make organizations more likely to pay the ransom rather than deal with extended downtime.
Those who use ransomware are all too familiar with these dynamics and intentionally plan their attacks to take advantage of these weaknesses. This strategic tactic is supported by attack data, with the most recent research showing that 53% of US attacks take place on weekends or holidays. The trend is especially noticeable in high-impact attacks on critical infrastructure and large corporations, where careful planning and timing are key elements of the threat actors’ strategy.
Why are businesses in Australia and New Zealand more at risk?
There are a few reasons why organizations in Australia and New Zealand have a higher risk of being targeted by ransomware. One of the main reasons is the time zone difference between the region and global security operations centers. This often results in a lack of monitoring during local holidays, which can lead to delayed responses to early warning signs. Additionally, many businesses in Australia and New Zealand have less redundant IT infrastructures compared to businesses in North America or Europe. This makes them more vulnerable to operational disruption when they are attacked.
ANZ businesses are particularly vulnerable to cyber attacks due to their high digital maturity. The quick adoption of cloud services, IoT technologies, and remote work arrangements has created security gaps in many organizations. These gaps are especially exploitable during periods of reduced vigilance.
Adding to these technical factors, many ANZ organizations have not yet fully updated their security programs to tackle the specific methods used in modern ransomware operations. While basic security measures are typically well-implemented, the advanced identity protection measures required to defend against current attack methods are less consistently deployed compared to other regions with similar threat profiles.
Is it ever a good idea for companies to pay the ransom?
Law enforcement and cybersecurity professionals strongly recommend not paying ransoms, as doing so supports criminal activities, incentivizes more attacks, and does not ensure complete data restoration. Companies that have robust backup systems, verified recovery methods, and suitable cybersecurity insurance usually fare better by not paying and instead focusing on recovery from clean backups, even if the initial recovery period takes longer. The decision ultimately involves balancing immediate business needs against the longer-term security consequences, including the increased risk of being targeted again once known as a company that is willing to pay.
What can small businesses with limited resources do to protect themselves?
Small businesses can greatly enhance their resilience to ransomware by focusing on high-impact, low-cost security measures. These include implementing multi-factor authentication across all systems, maintaining offline backups of critical data, using cloud-based security services that provide enterprise-level protection without the need for extensive in-house expertise, partnering with managed security service providers for holiday coverage, and developing simple but effective incident response plans that take into account limited resources. These fundamental measures address the most common attack vectors and require minimal ongoing investment, making them accessible even to organizations with tight security budgets.
What are the signs that a ransomware attack is imminent?
There are several warning signs that often precede a full ransomware deployment, giving vigilant organizations the chance to disrupt attacks before the encryption process starts. Unusual authentication attempts, especially outside of regular business hours or from unexpected locations, often indicate initial access efforts. The creation of new administrative accounts, changes to security settings, or modifications to backup configurations can signal that attackers are preparing for encryption deployment.
When cybercriminals are preparing to launch a ransomware attack, they often engage in network scanning activities first. They are particularly interested in identity systems or storage resources, as these can provide them with potential targets. If you notice unexpected software installations, particularly remote access tools or utilities that are often used in attack chains, such as PsExec or Cobalt Strike, this should be a red flag. You should investigate immediately.
When security logs or event data suddenly go missing, it’s usually a sign that attackers are trying to hide their actions before they start the final encryption phase. To make sure this crucial forensic data is still available even if the main systems are compromised, organizations need to put in place strong logging systems that send logs to a separate, secured infrastructure.
By keeping an eye out for these signs and setting up automatic warnings for any suspicious activities, companies can detect attacks during the initial stages of planning and preparation. During these stages, it is much easier and less disruptive to contain the attack than it would be to respond to fully deployed ransomware.
