Email malware campaigns have become a common method for cybercriminals who use social engineering tactics to trick users into compromising their systems. Attackers often disguise their emails to appear as if they’re coming from reputable organizations or trusted contacts. In many cases, these emails prompt recipients to click on links or open attachments, leading to the download of malicious software. For instance, phishing emails may direct you to fraudulent websites designed to steal your credentials, while spear phishing involves highly targeted emails that use personal details to appear authentic. Some campaigns even embed malicious code within images—a technique known as steganography—to bypass traditional security measures.
Forbes Magazine recently reported that criminals are using a novel way to put malware on your computer using email. Recent cybersecurity reports have identified sophisticated malware campaigns targeting Gmail and Outlook users by embedding malicious code within email images. Notable threats include VIP Keylogger and 0bj3ctivityStealer.
How the Malware Operates:
- VIP Keylogger: Disguised as invoices or purchase orders, these emails contain images embedded with malicious code. Once opened, the malware records keystrokes and extracts credentials from various sources, including applications and clipboard data.
- 0bj3ctivityStealer: Presented as requests for quotations, these emails include attachments that, when opened, download images from remote servers containing harmful code. This malware specifically targets account credentials and credit card information.

Attack Techniques:
Attackers employ steganography, embedding malicious code within images hosted on legitimate websites. This method allows them to bypass traditional security measures like web proxies that rely on reputation checks. For instance, one malicious image was accessed nearly 29,000 times, indicating the scale of these campaigns.

To avoid falling victim to these email threats, it’s important to exercise caution when handling emails. Always verify the sender’s details and be skeptical of unexpected messages, especially those that create a sense of urgency or request sensitive information. Take the time to hover over links to check their destination and avoid clicking on anything suspicious. Keeping your email client, operating system, and antivirus software up-to-date is also crucial, as these updates often include patches for newly discovered vulnerabilities.
Beyond these basic precautions, employing advanced security tools can offer an extra layer of protection. Robust spam filters and anti-malware programs are essential for blocking harmful content before it reaches your inbox. Enabling multi-factor authentication (MFA) can further secure your accounts, making it harder for attackers to gain access even if they manage to obtain your password. Finally, regular security training and awareness, including simulated phishing exercises, can help both individuals and organizations remain vigilant against evolving cyber threats, ensuring that every unexpected email is treated with the necessary caution.
