Understanding the Seasonal Trends of Cyber Threats

Cyber security has become a paramount concern for individuals, businesses, and governments alike and for good reason. Cyber attacks have grown not only in number but also in sophistication, posing significant risks to our online safety and security. One question we always get at Jera IT, is “are there such things as cyber attack patterns?” The answer is there are dozens! This blog will delve into annual cyber attack patterns, examining whether they occur more frequently at specific times of the year and identifying periods of peak and dip activity. Just like Santa, the cyber criminals are always on the lookout. We’ve used analysis supported by comprehensive statistics and sources, with a particular focus on the context of the UK, so read on and stay up to date on cyber attack patterns.

The Landscape of Cyber Attacks

Cyber attacks encompass a wide range of malicious activities, including phishing, malware, ransomware, and distributed denial-of-service (DDoS) attacks. The motives behind these attacks vary, from financial gain and political espionage to causing disruption and damage. Understanding cyber attack patterns of these attacks can help us better prepare and defend against them.

Seasonal Trends in Cyber Attacks

One of the key questions we seek to address is whether cyber attacks exhibit seasonal patterns. Do cyber criminals strike more frequently at specific times of the year? Are they sitting with a plate of mince pies waiting for us to drop our guard? By analysing data from various sources, we can identify potential patterns.

Winter (December to February): The winter months, particularly around the holiday season, often see a spike in cyber attacks. People panic buying the last few presents on their list on the web are a prime target for cyber criminals. With cyber criminals targeting unsuspecting consumers through phishing scams and fake e-commerce websites even the season of good will isn’t sacred to the scammers. According to a release by the UK’s National Cyber Security Centre (NCSC), the number of phishing attacks rises significantly during this time.

Spring (March to May): As the weather warms up and tax season approaches, cyber criminals shift their focus to exploiting tax-related vulnerabilities. The UK’s tax authority, HM Revenue and Customs (HMRC), frequently warns of phishing emails and fraudulent websites that attempt to steal personal and financial information.

Summer (June to August): The summer months often see a slight dip in cyber attack patterns, as people go on holiday and spend less time online. However, this period is not without its risks. Businesses may be particularly vulnerable during this time as key staff members take time off, potentially leaving gaps in cyber security defences. Just one of the many benefits of having a team of cyber security pros at your beck and call!

Autumn (September to November): The return to school and work after the summer break often coincides with a resurgence in cyber attacks. In particular, ransomware attacks tend to peak during this period. Cyber criminals take advantage of the increased online activity and the pressure on businesses to maintain operations during the busy back-to-school and pre-holiday seasons.

Monthly Variations in Cyber Attacks

Beyond seasonal trends, it is also important to examine the monthly variations in cyber attack activity. Certain months consistently show higher levels of cyber threats, while others experience relative lulls.

January: The start of the year often sees a continuation of the heightened activity from the holiday season. Cyber criminals exploit the influx of online shopping and the use of new devices received as gifts.

April: April is frequently marked by tax-related scams, as individuals and businesses prepare their tax returns. Cyber criminals use this opportunity to send fraudulent emails and create fake tax websites.

June: As summer begins, there is typically a slight decrease in cyber attack activity. However, businesses should remain vigilant, especially if they experience staff shortages due to holidays.

October: October often sees a notable increase in ransomware attacks. This uptick is likely due to cyber criminals targeting businesses that are under pressure to ensure smooth operations leading up to the holiday season.

Peaks and Dips in Cyber Attack Activity

Several factors can influence the peaks and dips in cyber attack activity throughout the year. These include global events, economic conditions, and changes in technology. By understanding these factors, we can better anticipate and mitigate cyber threats.

Influence of Global Events

Global events, such as major political elections or international crises, can significantly impact the frequency and nature of cyber attacks. For instance, during the COVID-19 pandemic, there was a surge in cyber attacks targeting remote workers and exploiting public fear and uncertainty. According to a report by the NCSC, the number of cyber incidents in the UK increased by 20% during the first few months of the pandemic!

Economic Conditions

Economic conditions also play a role in shaping cyber attack patterns. Periods of economic instability or recession can lead to an increase in financially motivated cyber crime. Cyber criminals may take advantage of individuals and businesses facing financial difficulties, using tactics such as phishing and ransomware to extort money.

Technological Advancements

The rapid pace of technological advancements can create new opportunities for cyber criminals. As new technologies emerge, so do new vulnerabilities. For example, the widespread adoption of Internet of Things (IoT) devices has led to an increase in attacks targeting these devices. Cyber criminals exploit weaknesses in IoT security to gain access to networks and steal sensitive information.

Conclusion

Our analysis of cyber attack trends reveals that these threats are not evenly distributed throughout the year. Instead, they exhibit distinct seasonal and monthly trends, with peaks and dips influenced by various factors. By understanding these patterns, we can better prepare for and defend against cyber threats.

In the UK, the winter months and specific periods such as tax season and the return to school and work are particularly high-risk times for cyber attacks. Businesses and individuals must remain vigilant and adopt robust cyber security measures to protect themselves during these periods.

As we continue to navigate the digital landscape, staying informed about the latest trends and developments in cyber security will be crucial. By doing so, we can stay one step ahead of cyber criminals and ensure the safety and security of our online world.
