Phishing remains a significant concern for both individuals and organizations. Recent findings from ThreatLabz have highlighted the alarming prevalence of phishing attacks targeting major brands, with Google, Microsoft, and Amazon emerging as the top three most impersonated companies.
This article explores the intricacies of these phishing tactics, the role of certificate authorities and domain registrars, and the broader implications for cybersecurity.
The Rise of Phishing: Google Leads the Pack
Phishing attacks have become increasingly sophisticated, leveraging brand recognition to deceive unsuspecting users.
According to ThreatLabz, Google accounted for the highest percentage of typosquatting and brand impersonation instances at 28.8%.
Microsoft followed closely at 23.6%, with Amazon at 22.3%. Meta, although also targeted, was far less affected at 4%.

The reason behind targeting these tech giants is clear: their vast global user bases offer a lucrative pool of potential victims.
Attackers mimic these brands to exploit the trust users place in them, making it easier to extract sensitive information or distribute malware.
Certificate Authorities: A Double-Edged Sword
One of the key tactics used by threat actors is the exploitation of HTTPS to create a facade of legitimacy for their phishing sites.
Among the analyzed phishing domains, 48.4% were found to have certificates issued by Let’s Encrypt.
This free and open certificate authority is popular due to its ease of use and minimal security checks, making it an attractive option for cyber criminals.
Google Trust Services accounted for 21.5% of the certificates, benefiting from Google’s strong brand trust.
GoDaddy issued 15.2% of the certificates, underscoring its significant market presence and the convenience it offers when registering domains.
Domain Registrars: The Backbone of Phishing Operations
Domain registrars play a crucial role in the registration of typosquatting and impersonation domains.
GoDaddy emerged as the most abused registrar, with 21.7% of the instances, followed by NameCheap at 7.3%, and NameSilo at 6.4%.
These registrars are favored by attackers for their reputation, cost-effectiveness, and privacy options.
Threat actors often choose commonly used top-level domains (TLDs) to make their phishing sites appear more legitimate.
The .com TLD was the most popular, used in 39.4% of cases. Interestingly, less common TLDs like .xyz and .top also saw significant use, at 11.1% and 5.4% respectively, likely due to their lower registration costs.
Malware Distribution
One notable example of malware distribution involved the domain “acrobatbrowser[.]com”, which impersonated Adobe.
The site displayed a fake Adobe page, automatically downloading an MSI file disguised as an Adobe plugin.
This file contained the Atera Remote Access Trojan (RAT), allowing attackers to gain remote control over a victim’s device.
Credential Theft
ThreatLabz identified the domain “offlice365[.]com” as a typosquatting site designed to steal credentials.
By mimicking the legitimate Office 365 website, it tricked users into entering their login information, which was then harvested by attackers.
Scammers have also used typosquatting to impersonate Amazon on platforms like WhatsApp, luring victims into sharing personal information.
Additionally, domains like “onedrivesync[.]com” have been used for command-and-control (C2) communication, disguising malicious activities as legitimate Microsoft OneDrive operations.
Typosquatting and brand impersonation remain potent tools in the arsenal of cybercriminals. By exploiting typographical errors and the trust users place in well-known brands, these deceptive domains can lead to significant data breaches and financial losses.
Understanding these tactics is crucial for both users and organizations to recognize and defend against phishing attacks.
