Digital advertising thrives on detailed insights gathered from users. Browsing patterns, purchasing behaviour, location data—all of these are tracked using cookies, tracking pixels, and behavioural analytics
In the digital age, data is often compared to oil—a valuable resource driving the operations of modern businesses. Companies collect vast amounts of information from their customers to personalise services, fine-tune marketing strategies, and ultimately increase sales. However, as brands become more data-driven, they inadvertently expose themselves and their customers to serious cybersecurity risks. The very technologies designed to improve user engagement can also be turned against users, putting them at risk of identity theft, financial fraud, and privacy violations.
Delphin Varghese, Co-founder and Chief Revenue Officer of AdCounty Media, highlights how advertising-driven data collection is increasingly vulnerable to exploitation by cybercriminals. “Every digital ad interaction—clicks, impressions, or conversions—generates a treasure trove of data points,” he notes.
Weak Links In Ad-Driven Data Collection
Digital advertising thrives on detailed insights gathered from users. Browsing patterns, purchasing behaviour, location data—all of these are tracked using cookies, tracking pixels, and behavioural analytics. While this allows brands to target ads more effectively, it also creates a goldmine of sensitive information for hackers.
One of the major risks lies in third-party data sharing. Most companies rely on third-party advertising platforms to manage and store user data. If these platforms are breached, sensitive details like email addresses, geolocation, and partial payment data may fall into the wrong hands. A prime example is the 2021 Facebook data breach, which exposed personal data of over 530 million users. The leaked information, including phone numbers and emails, later surfaced on hacking forums, as reported by Business Insider.
Tactics Used By Cybercriminals To Exploit Advertising Data
Cybercriminals use several methods to misuse advertising data:
Phishing & Social Engineering Attacks
Using targeted ads, attackers can deliver malicious links disguised as legitimate promotions. These links often lead users to fake landing pages designed to steal login credentials or credit card information. The Anti-Phishing Working Group (APWG) reported a 61 per cent rise in phishing attacks in 2022, underlining the growing threat.
Malvertising
Not all ads come from trusted sources. Malvertising refers to malicious code embedded in seemingly genuine advertisements. When clicked, these ads can install ransomware or spyware on users’ devices. According to Confiant’s 2023 Malvertising Trends Report, one out of every 200 ad impressions last year contained harmful code.
Data Scraping For Identity Theft
Hackers often scrape publicly available ad data and combine it with previously leaked information to build detailed personal profiles. These profiles can be used to commit identity theft, allowing fraudsters to apply for credit cards, loans, or gain unauthorised access to personal accounts.
Exploitation Of Location Data
Location-based advertising tracks users’ movements, offering another avenue for misuse. Criminals can potentially monitor individuals’ real-time locations. Research conducted by Princeton University in 2022 revealed that anonymised location data could often be reverse-engineered to identify individuals, raising serious privacy concerns.
Push For Stronger Regulations & Safeguards
Governments and regulatory bodies have begun addressing these risks. Laws such as the General Data Protection Regulation (GDPR) in the European Union and the California Consumer Privacy Act (CCPA) aim to give users greater control over their personal information. However, enforcement remains inconsistent, and cybercriminals often find ways to exploit loopholes.
Tech companies are also taking steps to limit data misuse. Apple’s App Tracking Transparency (ATT) feature restricts cross-app tracking, while Google plans to phase out third-party cookies by 2025. These efforts are intended to curb intrusive tracking practices, but whether they will be enough to outpace cybercriminal tactics remains to be seen.
As Varghese points out, while data remains a powerful tool for businesses, the responsibility to safeguard it is just as crucial. Without stringent protections and ongoing vigilance, the same data that fuels business growth can easily become a liability.
