Malicious ads are creeping into nearly every corner of our digital lives. From Facebook feeds to Instagram stories, they masquerade as ordinary promotions—promising impossibly steep discounts or exclusive items—only to lead unsuspecting users straight into scammers’ arms. As our attention spans shorten, these cleverly crafted traps grow more sophisticated, seizing on our desire for convenience and quick deals.
Recent data from Bitdefender Labs paints a troubling picture of the widespread nature of this threat. Throughout 2024, researchers detected approximately 800,000 malicious ads, many of which originated from more than 35,000 fraudulent or hijacked social media profiles. A closer analysis revealed 40,000 domains actively participating in malvertising campaigns. These domains leveraged two main tactics: masquerading as legitimate e-commerce sites or featuring deceptive ads that showcased celebrities to lure unsuspecting users.
The malicious profiles ranged from obscure accounts with a handful of followers to high-profile ones boasting millions, demonstrating that no social media audience—regardless of size—is safe from such infiltration. This further underscores the pervasive and adaptive strategies employed by threat actors to exploit social media platforms at scale.
The Anatomy of a Malicious Ad Campaign
At first glance, a malvertising campaign can look almost identical to a conventional online promotion. Criminals often replicate the branding of well-known businesses or public figures, and leverage banner images and product shots so polished they could pass for the real deal. In other instances, scammers deploy hastily crafted ads riddled with spelling errors and poor formatting. Yet, despite their sloppy presentation, these ads still succeed in capturing attention by making bold, eye-catching claims or promoting outrageously steep discounts to users.
What happens next depends on the scam’s intended target. Some ads redirect to bogus online stores that steal credit card details. Others lure victims to fake subscription pages, tricking them into paying hidden fees. Additionally, cybercriminals have begun leveraging deepfake technology to create convincing videos featuring fabricated celebrity endorsements. These videos are used to promote everything from miracle cures to fraudulent investment platforms, making their schemes appear more legitimate. In more alarming cases, simply clicking on an ad can trigger a hidden download that silently installs malware, enabling attackers to steal sensitive data from victims.
Celebrity Impersonations and High-Profile Targets
Among the most unsettling developments, Bitdefender Labs noted a surge in accounts exploiting the names or images of public figures and A-list celebrities. These accounts range from modest clones of well-known social media pages to sprawling networks with millions of followers. In addition to mesmerizing the audience with names and imagery of the rich and famous, deceptive profiles frequently share links that lure users to fraudulent storefronts, phishing sites, or malicious software bundles cleverly disguised as legitimate downloads.
Deepfake technology adds an additional layer of complexity to social media malvertising campaigns. Using advanced AI to superimpose faces and voices, scammers can create eerily convincing “endorsements” from celebrities, TV presenters, or internet influencers. These fabricated testimonials were found promoting dubious health supplements, unverified medical devices, or get-rich-quick investment schemes that prey on the trusting nature of eager viewers.
The Rise of AI-Driven Malvertising
Artificial intelligence has taken the world by storm, and cybercriminals are not missing out on the opportunity to exploit this trend. A growing number of analyzed ads purport to offer groundbreaking AI tools—everything from text generators to advanced design software—only to supply malware once the user downloads the program. Victims are often left with a compromised system, unwittingly granting attackers access to sensitive data or network credentials. In a marketplace flooded with new and legitimate AI offerings, sorting genuine innovation from criminal trickery can be difficult. That confusion is precisely what malvertisers exploit.
Impersonating Brands and Retailers
Impersonating reputable retailers is an evergreen tactic we see in malvertising campaigns.
Electronics, apparel, and household goods are some of the most common lures, offered at jaw-dropping discounts to entice bargain hunters. The websites connected to these ads feature near-identical layouts to well-known e-commerce platforms, complete with company logos and professional product photography. Once users submit their payment details, the only thing they’re left with is an empty bank account. In some cases, scammers go as far as providing tracking information, but these details are almost always fabricated, adding another layer of deception to their schemes.
In other cases, these faux webshops request additional personal data—like phone numbers, addresses, or identification documents—under the pretext of “verification.” In reality, the criminals are amassing a trove of details they can sell or reuse in future attacks.
A Global Network of Scams
Fraudulent ads are not limited to one type of platform or region. The vast range of compromised or malicious pages monitored by Bitdefender highlights the pervasive nature of these schemes. They can emerge anywhere—from small, tight-knit communities with only a few dozen members to seemingly legitimate, official-sounding pages with millions of followers. While many platforms actively scan and remove offending accounts, the relentlessness of these campaigns means new pages and ads appear at a rate that challenges even the most robust detection systems.
Adding to the challenge is the sheer number of domains—over 40,000 identified by Bitdefender alone—registered exclusively for malvertising purposes. These sites operate like digital chameleons, appearing suddenly to run scams for a few days or weeks before vanishing, only to resurface under new domain names. This evasive, ever-shifting behavior not only confounds users but also poses a significant challenge for cybersecurity professionals, making it incredibly difficult to track and dismantle every malicious campaign.
Key Warning Signs
Despite the cleverness of malvertisers, certain red flags can help users and businesses stay safe:
Deals That Defy Logic
A 90% discount on a brand-new, high-demand item should raise an eyebrow. Real sales rarely slash prices so drastically overnight.
Awkward Errors or Mismatched Design
While some criminals invest in professional-quality visuals, many fail to maintain consistent branding, often mixing up color schemes or featuring bizarre grammatical mistakes.
Questionable Endorsements
Any celebrity plug that seems too generic, poorly animated, or poorly translated is worth a closer look. Deepfakes can be impressively authentic at first glance, but with a bit of scrutiny, inconsistencies often emerge.
Insistence on Quick Action
Scam ads frequently employ time pressure, pushing viewers to act immediately. Legitimate sellers welcome comparisons and rarely demand payment via unorthodox methods like prepaid debit cards or wire transfers.
Lack of Contact Information
Companies offering genuine products typically provide transparent ways to reach customer support. When a site or page lacks phone numbers, email addresses, or even a physical mailing address, it’s almost always fishy.
What Users and Organizations Can Do
A few simple steps can dramatically reduce the risk of being ensnared by a malicious campaign. First, resist the urge to click on every flashy ad. Instead, navigate directly to a brand’s official website by typing the URL into your browser. Regularly updating antivirus software and enabling phishing protection features offers an added layer of defense. If something looks or sounds suspicious, report it to the platform administrators, who can investigate and possibly dismantle the operation.
Businesses also have an important role to play. Companies large and small should keep close tabs on their own branding, searching major platforms for ads or pages that misuse their logos or images. They should also educate employees on recognizing threats since one careless click can undermine even the most sophisticated security measures.
A Collective Responsibility
Malvertising has become an unwelcome staple of online advertising. From deepfake celebrity endorsements to bogus AI apps, the sheer scale exposed by Bitdefender Labs reveals a complex underworld thriving on public trust. Though social networks work diligently to remove malicious content, they face an uphill battle against a global network of scammers adept at imitating real ads and rebranding themselves whenever detected.
Ultimately, every individual click represents a point of vulnerability—but also a potential barrier to scam success. By learning to spot suspect deals, verifying accounts, and reporting malicious activity, users become active defenders of the digital commons.
Malvertising may never disappear entirely, but its impact can be curbed through cooperation, education, and smart technology. Where criminals weaponize our habits and impatience, informed vigilance remains the best shield. If you come across an ad that seems too good to be true—or worse, too slick to be real—take a moment to pause and consider the cost of a single click. The era of malicious advertising is upon us, but with eyes wide open, we can keep its damage in check.
