What Are the Top Email Threats to Watch for in 2024?

The dynamic and rapidly evolving landscape of cybersecurity continues to present new challenges, particularly in the realm of email security. With the growing sophistication in cyber threats, understanding past threats is crucial for anticipating and preparing for future dangers. This article delves into the top email threats to watch for in 2024, based on insights from VIPRE Security Group’s annual email threat landscape report.

Spam Emails

Spam remains a significant issue, with nine out of ten emails received in 2024 categorized as spam. This overwhelming prevalence emphasizes the persistent annoyance and potential risk that spam poses to email users globally. The commercial purpose behind much of the spam—making up 37% of the total spam emails sent—highlights its nuisance value. However, the more alarming statistic is that 62% of these spam emails are actively malicious. These malicious emails aren’t merely annoying spam but dangerous threats designed to deceive and damage.

Malicious Spam Categories

Malicious spam emails were divided into scams (32%), phishing (21%), and malware (9%). These categories pose serious threats to both individuals and organizations. Scam emails often trick individuals into divulging financial information or transferring funds to fraudulent accounts. Phishing emails employ deceptive tactics to steal personal and sensitive information by disguising themselves as legitimate entities. Malware spread through these emails can infect systems, leading to severe consequences such as data breaches or system failures. The substantial percentage of these malicious spam emails reiterates the importance of staying vigilant and implementing strong security measures to guard against such threats.

Prevalence of Spam

The sheer volume of spam alone stands as a testament to the determined efforts of cybercriminals targeting email users. Nine out of ten emails in 2024 being categorized as spam underlines the massive scale of this issue. Despite many emails being merely commercial outreach, implying little harm, the fact that a significant 62% are actively malicious cannot be disregarded. These percentages highlight an urgent need for advanced spam-filtering mechanisms and continuous user education. Active measures against spam mitigation are essential, not solely because of the excessive quantity but due to the genuine threats embedded in these emails that could result in financial loss or system vulnerabilities.

Malware Families

Top Malware Families of 2024

The top malware families of 2024 included PikaBot in Q1, IceID in Q2, and Redline in Q3 and Q4. These malware families wreaked havoc, infiltrating systems and causing significant damage. Infostealers and Remote Access Trojans (RATs) were particularly prevalent among these malware types. Infostealers specifically have become a major threat as they siphon off sensitive information such as login credentials, personally identifiable information (PII), and intellectual property (IP). This stolen data can be sold on the dark web or used for subsequent attacks. As these malware variations evolve, they continuously find new ways to bypass traditional security filters, making them a persistent and pervasive threat.

Consequences and Protection

The consequences for victim organizations can be dire, often resulting in regulatory fines, loss of consumer trust, and operational disruptions. Protecting against these evolving threats necessitates a multi-layered approach to cybersecurity. Despite their increasing sophistication, the core protection mechanisms remain the same. Security awareness training is paramount in educating users about evolving threats and helping them recognize potential risks. Multi-factor authentication (MFA) adds an extra layer of security by requiring multiple forms of verification before granting access. Endpoint detection and response (EDR) systems are crucial for identifying and neutralizing threats before they can infiltrate further into a network. Implementing these measures can significantly mitigate the risks posed by infostealers, RATs, and other malware threats.

Business Email Compromise (BEC)

Rise of BEC Scams

BEC scams emerged as a significant threat in 2024, employing cunning and sophisticated methods to deceive businesses. Cybercriminals posing as high-ranking executives or trusted vendors manage to trick employees into performing actions that can severely impact their organization. These actions include transferring funds to fraudulent accounts, clicking on malicious links or attachments, or divulging sensitive company information. According to the FBI’s Internet Crime Report, BEC scams resulted in over $2.9 billion in losses in 2023. These staggering financial implications highlight the severity of BEC scams and the need for stringent preventative measures.

Impersonation Tactics

Impersonation tactics are the cornerstone of BEC scams, with 70% of all scam emails in Q4 2024 involving such techniques. Cybercriminals craft their approaches meticulously, often acquiring extensive information about their targets to make their impersonations convincing. The majority (88%) of these scams involved impersonation, showcasing its effectiveness in deceiving employees. Notable incidents, such as the Singaporean company that inadvertently transferred $42.3 million to a fraudulent supplier, underscore the potential catastrophic consequences of falling prey to BEC scams. Implementing strict email verification processes and conducting regular employee awareness training are critical. These measures help ensure that employees can identify and respond appropriately to potential BEC scams.

Phishing Phrases

Common Phishing Phrases

Recognizing common phishing phrases is essential in staying vigilant and protecting oneself from potential scams. Cybercriminals use specific trigger phrases designed to create a sense of urgency, enticing users to take action without scrutinizing the email. The top five phishing phrases in 2024 were: “CLICK HERE to upgrade,” “Please Access Your Account to review it,” “Sign-in activity review,” “New voicemail received!” and “Your subscription is about to expire!” These phrases reflect a variety of ruses employed by cybercriminals to make their emails appear compelling and legitimate. Educating users on recognizing these common phrases can help them remain cautious and less likely to fall victim to such schemes.

Crafting of Phishing Messages

Phishing messages are carefully crafted to manipulate recipients into clicking on malicious links or providing sensitive information. The success of phishing attacks largely depends on the ability of these messages to mimic legitimate communication. By creating a perceived need for immediate action, whether it is upgrading an account or reviewing sign-in activity, cybercriminals play on the recipient’s fears and doubts. Understanding how these messages are engineered is vital in developing the skills to identify and avoid them. Regular training and awareness programs can equip users with the knowledge needed to spot phishing attempts and take appropriate action to protect their information.

Key Takeaways

Increasing Sophistication of Email Threats

The overarching trend is the increasing sophistication of email threats and the necessity for continuous vigilance and proactive measures. Cybercriminals are perpetually refining their tactics, making it imperative for individuals and organizations to adopt a proactive stance in email security. While spam remains a significant and prevalent issue, the rise of actively malicious spam necessitates heightened awareness and robust cybersecurity practices. Staying informed about the latest trends in email threats and implementing comprehensive protective measures are critical components in the overarching strategy to maintain security.
