The internet, a gateway to a plethora of information, remains a significant part of daily life, with users relying on search engines like Google maor Bing to gather insights.
However, this seemingly innocuous activity is increasingly becoming a target for malicious actors.
By manipulating search engine algorithms or creating fraudulent ads, cybercriminals are able to present deceptive websites as trustworthy sources within top search results, posing a serious threat to unsuspecting users.
Cybercriminals Use SEO Poisoning and Fake Ads to Exploit Search Engine Dynamics
Recent findings reveal a trend of cyberattacks where threat actors exploit users’ tendency to blindly trust top search results.
One notable method employed is SEO poisoning, sometimes referred to as black hat SEO, wherein malicious websites are strategically optimized to rank higher on search engine results pages.
A 2021 investigation by cybersecurity researchers at ESET highlighted the use of a server-side trojan that hijacked the credibility of legitimate websites, thereby enhancing the visibility of malicious sites.
Similar manipulative campaigns have continued to surface, underscoring the persistence of these tactics.
Fake Search Ads as a Preferred Malicious Tool
Another widespread method involves malicious advertising. Fraudsters purchase ads that seamlessly integrate with search engine results and impersonate trusted websites to lure victims.
A recent example includes a campaign targeting Chinese speakers, where threat actors deployed fake sites resembling reputable brands like Firefox, WhatsApp, and Telegram to gain control of victims’ devices.
Counterfeit ads for popular AI tools, like ChatGPT and DeepSeek, have also surged, enticing users into sharing sensitive details such as credit card information.
The proliferation of fake ads extends further, affecting industries like financial services and public transportation.
In Latin America, for example, ESET researchers uncovered scams impersonating businesses like La Veloz del Norte to steal user credentials and banking details from travelers seeking bus tickets online.
Similarly, scams targeting Mastercard users via deceptive ads led to further exploitation of financial data.
Google, being a major search engine, has acknowledged the threats posed by deceptive ads.
According to its 2023 Ads Safety Report, the company blocked over 5.5 billion ads and suspended 12.7 million advertiser accounts, reflecting an ongoing effort to counter malvertising.
However, some scams still evade detection, necessitating additional awareness among users.
Users are advised to remain vigilant about the risks associated with both organic and paid search results.
Clicking on prominent listings without scrutiny can lead to severe consequences, including data theft and device compromise.
Threat actors often employ typosquatting techniques registering domains that closely resemble legitimate ones to deceive users. A case in point is “telegraem[.]org,” which mimicked the popular Telegram platform.
When navigating search results, individuals should closely examine URLs for inconsistencies, verify website authenticity, and avoid making assumptions about legitimacy based solely on ranking.
Tools like Google’s “About this ad” feature, accessible via the three-dot menu next to sponsored listings, can help users uncover discrepancies in claims.
Furthermore, employing robust security measures such as updated antivirus software, strong passwords, and two-factor authentication adds an essential layer of protection.
Despite the advent of AI-driven search features, the traditional “search-and-click” behavior remains deeply ingrained in user habits.
This predictability offers cybercriminals opportunities to exploit search engines for malicious purposes.
To remain secure in the face of such threats, users must adopt a cautious approach, question the authenticity of seemingly credible results, and leverage protective tools to ensure their online safety.
As search engines continue refining their defenses, user awareness and proactive behavior remain pivotal in combating cyber threats.
