Summer is here, and for many organizations, that means lighter workloads, vacation schedules, and a general slowdown in business operations. However, for cybercriminals, it’s a different story altogether – they see summer as an ideal time to launch attacks, taking advantage of reduced staffing levels and slower response times.
According to data, there’s a 40% increase in cyberattacks during holiday periods, with the summer months being particularly vulnerable. When security teams are operating with reduced staff, they face a daunting challenge: managing the same volume of work with fewer people available. This can lead to operational bottlenecks across the organization, causing patch cycles to be delayed, vulnerabilities to remain unaddressed for longer, and investigations to take longer to resolve.
One of the main concerns is that senior engineers often take planned time off during the summer months, leaving critical decisions and complex investigations to junior team members. This can lead to slower response times during an incident, as well as reduced institutional knowledge – the person who understands why a server behaves unusually or can quickly interpret an obscure alert may not be available.
These staffing gaps create ideal conditions for attackers, who can exploit the reduced oversight and take advantage of common attacks like phishing and Business Email Compromise (BEC). These types of attacks are particularly insidious because they often rely on social engineering tactics that can make it harder to spot them. With approval chains disrupted and key decision makers out of the office, employees may be less likely to verify urgent requests or question suspicious emails.
The real danger is not just that attacks increase during vacation periods – it’s that lean staffing can make common attacks harder to spot and easier to act on. According to a recent Kaseya Email Security Report, attackers are increasingly using AI to make phishing attacks more convincing and scalable, making traditional warning signs less reliable. This means that even experienced security teams may struggle to identify and respond to these types of threats.
The longer attackers remain inside a network, the more opportunities they have to steal credentials, access sensitive data, move laterally or launch a ransomware attack. This is known as dwell time, and it’s a major concern for organizations operating with reduced staffing levels during the summer months. The solution lies in implementing automation, monitoring, and response capabilities that can maintain strong protection even when key personnel are out of the office.
Ultimately, the problem is not just about vacation schedules – it’s that many security operations still rely heavily on human availability. With modern environments generating thousands of alerts every day, manual processes become bottlenecks during periods of reduced staffing. Every delay extends the window attackers have to exploit vulnerabilities and deepen their access into an organization’s network.
To mitigate these risks, organizations should focus on implementing robust automation and monitoring capabilities that can detect and respond to threats in real-time, even when key personnel are away. By doing so, they can maintain strong protection and minimize the risk of attacks during the summer months.
