Malvertising, or malicious online ads, continues to rise as cybercriminals grow more sophisticated. In fact, incidents surged by 42% last year, with deceptive ads appearing in Google searches or on trusted websites, tricking users into phishing scams or injecting malware into devices.
Hackers are now impersonating well-known brands, making it harder for users to detect threats.
With the risk of infection and data theft at an all-time high, prioritizing awareness and strengthening cybersecurity efforts is crucial to avoid falling victim to these attacks. Even clicking on seemingly legitimate ads or visiting certain websites can expose users to serious risks, making caution essential.
Why It Matters: Malvertising is a growing threat that targets users through trusted platforms. Hackers exploit search engines to deliver phishing and malware attacks, making employees and corporate networks vulnerable. For CIOs, the rise in incidents means a higher risk of data breaches, operational disruptions, and financial loss.
- Increased Malvertising Activity: Last year saw a 42% month-over-month spike in malvertising attacks, marking a surge in both the volume and sophistication of these cyber threats. Cybercriminals increasingly target major brands, luring users through malicious ads disguised as official content.
- Phishing and Malware Through Familiar Brands: Corporate employees and consumers alike are being tricked by ads posing as trusted companies. A notable example involves a fake Google ad for Lowe’s, which led employees to a phishing site. Similar tactics have been used to impersonate platforms like Slack, directing users to download malicious software.
- Risks of Routine Web Use: Malvertising can strike through both search engine results and ads on trusted websites. Users are often vulnerable just by clicking on a malicious ad, but in some cases, merely visiting an infected website is enough to trigger a “drive-by-download” attack that can compromise their system.
- Best Practices for Protection: Avoid clicking on sponsored search ads, verify URLs, and ensure software and browsers are up-to-date. Installing anti-malware and using ad-blockers or privacy-focused browsers can significantly reduce exposure to malvertising. Reporting suspicious ads also helps mitigate risks for others.
