Acronis Report Exposes 293% Spike in Email Attacks

Acronis, a global leader in cybersecurity and data protection, today shared new research findings from the first half of 2024 in its biannual cyberthreats report by Acronis Threat Research Unit. Titled, “Acronis Cyberthreats Report H1 2024: Email attacks surge 293%, new ransomware groups emerge,” the report leverages over one million unique Windows endpoints from 15 key countries around the world to bring awareness to global trends in the cybersecurity industry. Most notably, the report found that email attacks have seen a 293% surge when compared to the same period in 2023. The number of ransomware detections was also on the rise, increasing 32% from Q4 2023 to Q1 2024.

Ransomware continues to be a major threat to small and medium-sized businesses (SMBs), particularly in critical industries such as government and healthcare. In Q1 2024, Acronis observed 10 new ransomware groups who together claimed 84 cyberattacks globally. Among the top 10 most active ransomware families detected during this time, three highly active groups stand out as the primary contributors, collectively responsible for 35% of the attacks: LockBit, Black Basta, and PLAY.

In support of Acronis’ mission to tailor business initiatives to Managed Service Providers (MSPs), the report is observant of how MSPs are being targeted and compromised. Of note, attack vectors including phishing and social engineering, vulnerability exploits, credential compromises and supply chain attacks were highlighted as the most successful techniques used to breach MSPs’ cybersecurity defences.

“As a result of the increasing volume and complexities of cyber threats we continue to uncover in the current cybersecurity landscape, it is of the utmost importance that MSPs take a holistic approach to securing their customer’s data, systems, and unique digital infrastructures,” said Irina Artioli, report author and Cyber Protection Evangelist at Acronis Threat Research Unit. “To do this effectively, we recommend MSPs adopt a comprehensive security strategy, including mandating security awareness training and incident response planning, as well as deploying advanced endpoint protection solutions like extended detection and response (XDR), multi-factor authentication, and more.”

Additionally, the report focuses on emerging cybersecurity trends, highlighting the increasing use of generative artificial intelligence (AI) and large language models (LLMs) by threat groups. Specifically, it underscores the growing prevalence of AI being leveraged in social engineering and automation attacks. The most common AI-generated attacks that were detected include malicious emails, deepfake business email compromise (BEC), deepfake extortions, KYC bypass, and script and malware generation. Furthermore, Acronis researchers have identified two types of AI threats. The first involves AI-generated threats, in which malware is created using AI techniques but does not utilise AI in its operations. The second is AI-enabled malware, which incorporates AI into its functionality.

Other key findings from the report include:

Global Threat Landscape:

• Bahrain, Egypt, and South Korea were the top countries targeted by malware attacks in Q1 2024.
• 28 million URLs were blocked at the endpoint in Q1 2024.
• 27.6 % of all received emails were spam and 1.5% contained malware or phishing links.
• The average lifespan of a malware sample in the wild is 2.3 days.

• 1,048 cases of ransomware were publicly reported in Q1 2024, a 23% increase over Q1 2023.

Acronis Cybersecurity Trends in H1 2024:

• Ransomware continues to be a major threat to SMBs, and ransomware groups have abused vulnerable drivers to get a foothold in systems and disable security tools.
• In the first quarter of 2024, PowerShell was the most frequently detected MITRE technique.
• The number of email attacks detected in H1 2024 surged by 293% compared to the first half of 2023.

Ransomware Trends:

• In Q1 2024, Acronis researchers observed 10 new ransomware groups that together claimed 84 cyberattacks globally.
• The number of ransomware detections increased 32% from Q4 2023 to Q1 2024.

Attacks on MSPs:

• MSPs were under consistent attack from January to May 2024, with data revealing email phishing campaigns were the most used by attackers.
• The top five most frequently discovered MITRE ATT&CK techniques in the first half of the year included PowerShell, Windows Management Instrumentation, Process Injection, Data Manipulation and Account Discovery.

Phishing and email attacks:

• Organisations experienced a surge in email communications, with the number of emails per organisation increasing by 25%.
• The rise in email volume coincided with a 47% increase in email attacks targeting organisations.
• 26% of users encountered phishing attempts through malicious URLs.
• Social engineering increased by 5% since H1 2023; however, malware attacks decreased from 11% in H1 2023 to 4% in H1 2024.

Leveraging AI:

• Cybercriminals continue to leverage malicious AI tools like WormGPT and FraudGPT.
• While AI can assist attackers at every stage of the cyberattack kill chain, it can also be used as a defence mechanism as it allows for around-the-clock detection of attacks and reports them to experts to take appropriate response actions to ensure smooth business continuity.

The Acronis H1 2024 Cyberthreats Report is curated by Acronis Threat Research Unit and includes data surrounding ransomware threats, phishing, malicious websites and software vulnerabilities, and tips on how to protect against the aforementioned threats. Released bi-annually, the Acronis Cyberthreats Report sets the industry standard by consistently establishing itself as a benchmark for cybersecurity intelligence. Acronis’ analysis of the current cyber threat landscape is published for the benefit of its users, partners, and the broader, global cybersecurity community to help them stay abreast of ongoing cybersecurity developments.
