A cybersecurity experiment conducted by Sharjah Police has revealed how easily QR codes can mislead individuals, particularly when these codes promise conveniences such as free WiFi. The police placed an unbranded QR code in a public area with a simple message, “Free WiFi”, to measure how many people would scan it without verifying its source.
The results revealed that 89 members of the public scanned the code without asking who placed it or whether it was legitimate. According to Sharjah Police, the willingness to scan unfamiliar QR codes shows how quickly people act without considering potential cyber risks.
Officers stressed that the problem lies less in technology and more in user behavior. “A single scan can expose sensitive information,” police explained, noting that malicious QR codes can redirect users to fraudulent websites, initiate spyware downloads, or facilitate unauthorized access to personal accounts. With QR codes now common in restaurants, retail outlets, and advertising, attackers increasingly rely on this familiarity to trick unsuspecting users.
User Behavior Identified Behind Free WiFi Vulnerability
Sharjah Police stated that cybercriminals often depend on user interaction rather than technical loopholes. The force reiterated a simple rule for digital safety: Before scanning, ask yourself, ‘Do I trust the source?’ If the answer is uncertain, police advise against proceeding.
Authorities added that awareness remains the first line of defense. As QR codes continue to be integrated into payment systems, online services, and day-to-day transactions, taking a moment to verify the legitimacy of a code can prevent digital harm.
Sharjah Police also confirmed that they will continue launching public awareness initiatives to educate residents about new cyber threats and to promote safer online habits throughout the emirate.
A Quick Look at Global Trends
While Sharjah’s experiment stressed the local behavioral risks, similar concerns are coming out internationally. Cyble Research & Intelligence Labs (CRIL) recently published findings on an ongoing global quishing campaign it has named “Scanception.”
According to CRIL, this campaign uses QR codes embedded in phishing emails and PDF attachments to deliver credential-harvesting links. The attack shifts the threat to personal mobile devices, often outside an organization’s security perimeter, after victims scan the code. CRIL reported over 600 unique phishing PDFs and related emails discovered in just three months, with nearly 80% registering zero detections on VirusTotal.
These PDFs often mimic enterprise workflows, such as HR documents. One example involved a fake employee handbook with four pages of professional content, ending with a prompt to scan a QR code. In another case, victims who scanned a code were ultimately funneled to a counterfeit Office 365 sign-in portal designed to steal credentials through Adversary-in-the-Middle (AITM) techniques.
CRIL noted additional evasive features, including the detection of automation tools like Selenium or Burp Suite and the use of redirected URLs from trusted platforms such as YouTube, Google, Bing, Cisco, and Medium.
Targeting has been observed across more than 50 countries, with notable activity in North America, EMEA, and APAC, and concentrated attacks on Technology, Healthcare, Manufacturing, and BFSI sectors spanning more than 70 industries.
Strengthening Public and Organizational Awareness
Both Sharjah Police and Cyble’s research arm, CRIL, point to the same overarching lesson: the human element remains the most targeted and most vulnerable point in modern cyberattacks. Whether through a simple fake free WiFi QR code placed in a public space or through global campaigns like Scanception, attackers continue to exploit trust, familiarity, and routine digital behavior to bypass traditional security controls.
The guidance from experts is consistent; individuals and organizations must stay vigilant, verify QR code sources, strengthen security awareness programs, and adopt tools capable of analyzing attachments, embedded QR codes, and new attack patterns. A
