Email Attacks Doubled In 2023

Uploaded on 2024-03-08 in NEWS-Cybersecurity News, FREE TO VIEW

The leader cyber security firm Acronis has released findings of its regular cyber threats report for the second half of 2023 called Acronis Cyberthreats Report H2 2023. Notably, it uncovers the rise of Generative AI (Gen-AI) systems to create malware and orchestrate serious cyber attacks.

The report provides an in-depth analysis and prescriptive outlook on key security issues and prevalent cyber-threats worldwide.

By leveraging data collected from over 1,000,000 unique endpoints across 15 key countries, the findings conclude that AI-enhanced phishing affected over 90% of organisations and contributed to a 222% surge in email attacks in 2023 as compared to the second half of 2022.

Ransomware variants have decreased, yet the most effective attack vector are still causing companies across the globe to lose both their data and their money. In particular, Acronis identifies the lack of strong security solutions which should be detecting the exploitation of zero-day vulnerabilities.

Organisations are falling victim to attacks due to the delay in patching vulnerable software which allows threat actors to gain domain administrative rights, uninstall security tools and infiltrate sensitive information.

“There’s a disturbing trend being recognised globally where bad actors continue to leverage ChatGPT and similar generative AI systems to increase cyberattack efficiency, create malicious code, and automate attacks,” observed Candid Wüest, Acronis VP of Product Management. “Now, more than ever, corporations need to prioritise comprehensive cyber protection solutions to ensure business continuity.” he said.

These IT resources are allies to businesses who seek robust IT infrastructure and sound cyber security but because they centralise services to numerous businesses, from SMBs to large corporations; the scaling efficiencies that make them a business asset also make them a single point of failure where cyber criminals can exploit multiple entities through a single attack.

The report notes how more advanced tactics like supply chain attacks, AI-driven attacks and state-sponsored incursions are likely to intensify. MSPs should brace themselves for threats unique to their operations, including "island hopping," in which attackers use an MSP's infrastructure to attack clients, as well as "credential stuffing," which exploits an MSP's broad access to systems.

Key findings and themes from the report include:

Global Threat Landscape

Singapore, Spain, and Brazil emerged as the most targeted focus countries for malware attacks in Q4 2023.

Acronis blocked nearly 28 million URLs at the endpoint in Q4 2023, reflecting a 36% decrease compared to Q4 2022.

33.4% of received emails were identified as spam, with 1.5% containing malware or phishing links.
The average lifespan of a malware sample in the wild is 2.1 days.

In Q4 2023, 1,353 ransomware cases were explicitly mentioned, with notable contributions from LockBit, Play, ALPHV and the active Toufan group.

Cyber Security Trends H2 2023

Ransomware remains a major threat to large and medium-sized businesses, impacting critical sectors such as government and health care.

Data stealers are the second most prevalent threat, contributing to most data breaches.

The use of generative AI systems, including ChatGPT, for launching cyberattacks and creating malicious content is on the rise.

Ransomware Trends

Known ransomware gangs in 2023 include LockBit, Cl0P, BlackCat / ALPHV, Play, and 8Base.

The ALPHV gang, whom the FBI targeted in December 2023, breached over 1,000 entities, demanded over $500 million, and received over $300 million in ransom payments.

Regardless of a decrease in ransomware variants, businesses continue to suffer data and financial losses.

Attacks on MSPs Are Increasing

Attacks on managed service providers (MSPs) continue, with a recent high-profile breach affecting multiple US (United States) government agencies.

Microsoft cloud email account vulnerabilities led to the compromise of 60,000 emails from 10 US State Department accounts.

Phishing & Amail Attacks Remain The Main Attack Vectors

The total number of email-based attacks detected in 2023 increased by 222%.

Organisations experienced a 54% increase in the number of attacks per organisation.

91.1% of organisations faced AI-enhanced phishing attacks.

Cyber Criminals Embrace Malicious AI Tools

Cyber criminals are leveraging malicious AI tools, including WormGPT, FraudGPT, DarkBERT, DarkBART and ChaosGPT.

The public release of ChatGPT has increased the use of generative AI for cyberattacks.

Bad actors continue to profit from these activities and are leveraging AI-enhanced techniques to create more convincing phishing schemes, guaranteeing that this problem will continue to plague businesses.
