QR Codes Are The New Phishing Attack Method – Quishing

Evolution of Phishing: The Rise of QR Code Attacks on Corporate Scamming

As technology advances, so do the tactics of cybercriminals. Phishing, a form of cybercrime that relies on deception to steal sensitive information, has undergone significant evolution over the years. One of the latest innovations in this realm is QR codes phishing, also known as “quishing.” This article delves into the emergence of QR code attacks, their implications for organizations, and strategies for mitigating this evolving threat.

What are QR Barcodes?

QR codes, short for Quick Response codes, are two-dimensional barcodes that contain information encoded within a square grid of black squares on a white background. Developed in 1994 by Denso Wave, a subsidiary of Toyota, QR codes were initially used in the automotive industry for tracking parts during manufacturing. However, their versatility and ease of use have led to widespread adoption across various industries and applications.

QR codes can store a wide range of data types, including:

• Text: QR codes can encode alphanumeric characters, allowing them to store text-based information such as website URLs, contact details, or simple messages.
• URLs: One of the most common uses of QR codes is to encode website URLs. Scanning a QR code containing a URL can quickly direct users to a specific webpage without the need to manually type the address.
• Contact Information: QR codes can store contact details such as names, phone numbers, email addresses, and physical addresses. Scanning these codes can automatically add the contact information to a user’s address book.
• Wi-Fi Credentials: QR codes can encode Wi-Fi network credentials, including SSID (network name) and password, allowing users to quickly connect to a wireless network without manually entering the information.
• Geolocation Coordinates: QR codes can encode geographic coordinates (latitude and longitude), enabling users to navigate to a specific location using mapping applications.

QR codes are designed to be easily scanned and decoded using a smartphone or dedicated QR code reader. Once scanned, the encoded information is extracted and presented to the user, who can then take appropriate action based on the content of the QR code.

The adoption of QR codes has expanded rapidly in recent years, driven by factors such as increased smartphone penetration, improved camera technology, and the need for contactless interactions. QR codes are now used in various applications, including marketing campaigns, ticketing systems, payment solutions, inventory management, and COVID-19 contact tracing.

Overall, QR codes provide a convenient and efficient means of sharing information digitally, making them a valuable tool for businesses, organizations, and individuals alike.

QR Codes Attacks: The New Face of Phishing

QR codes phishing involves the use of QR codes embedded in emails or other digital communications to deceive recipients into disclosing sensitive information. These malicious QR codes typically lead to fake login pages or websites designed to capture login credentials, financial data, or other personal information. Despite being a relatively new tactic, QR code attacks have gained traction among cybercriminals due to their effectiveness and the widespread adoption of QR code technology.

Recent research has revealed alarming trends in QR code attacks:

• Targeting C-Suite Executives: High-ranking executives are prime targets for QR code attacks, receiving 42 times* more attacks than the average employee. Cybercriminals exploit the authority and access of executives to gain entry into organizational networks and extract valuable data.
• Industry-Specific Targeting: Certain industries, such as construction and engineering, are disproportionately targeted by QR code phishing campaigns. These sectors experience Quishing attacks at a rate 19 times higher than others, highlighting the need for tailored security measures in vulnerable industries.
• Credential Phishing Dominance: A staggering 89.3%* of QR code attacks are credential phishing attempts. By tricking users into entering their login credentials on fake websites, cybercriminals can hijack accounts, steal sensitive data, and launch further attacks.

The Persistence of BEC and VEC Attacks

While QR code phishing represents a novel threat, cybercriminals continue to rely on traditional attack methods such as Business Email Compromise (BEC) and Vendor Email Compromise (VEC). BEC attacks, in which threat actors impersonate company executives or trusted partners to deceive employees into transferring funds or sensitive information, have surged by 108% year-over-year. Similarly, VEC attacks, targeting vendors and suppliers to compromise payment systems or supply chains, have seen a 50% increase in frequency.

These sustained upward trends underscore the adaptability and persistence of cybercriminals in exploiting email as a vulnerable attack vector. As organizations fortify their defenses against emerging threats like QR code phishing, they must remain vigilant against established attack techniques like BEC and VEC.

Email: A Universal Target for Cybercrime

Email remains the cornerstone of business communication, offering a convenient and ubiquitous platform for exchanging information. Unfortunately, this universal reliance on email also makes it a lucrative target for cybercriminals seeking to exploit vulnerabilities in organizational defenses. With millions of new employees entering the workforce annually, threat actors have a constant stream of potential targets to exploit.

Phishing: The Ever-Present Threat

Phishing attacks, including QR code phishing, continue to pose a significant risk to organizations worldwide. Credential phishing, in particular, accounts for over 73%* of all advanced email attacks, making it the most prevalent form of cybercrime. Despite its relatively low ranking in terms of total losses, phishing serves as a gateway to a wide range of malicious activities, from data theft to financial fraud.

The Appeal of QR Code Phishing

QR code phishing represents a significant advancement in phishing tactics, leveraging familiar technology to deceive unsuspecting users. Several factors contribute to the appeal of QR code attacks for cybercriminals:

• Widespread Adoption: The ubiquity of QR codes in everyday life, from restaurant menus to event tickets, makes recipients less suspicious of scanning QR codes received via email.
• Security Bypass: QR codes bypass traditional email security measures by redirecting targets to external websites, minimizing the detection footprint of phishing campaigns.
• End-User Trust: End users are less likely to scrutinize QR codes compared to hyperlinks, creating an opportunity for attackers to exploit trust and familiarity.

Mitigating the Threat of QR Code Attacks

As organizations confront the growing menace of QR code phishing, proactive measures are essential to mitigate the risk of compromise:

• Employee Education: Provide comprehensive training and awareness programs to educate employees about the dangers of QR code phishing and how to recognize suspicious communications.
• Email Security Solutions: Deploy advanced email security solutions capable of detecting and blocking phishing attempts, including those utilizing QR codes.
• Security Policies: Implement robust security policies and procedures governing the use of QR codes in digital communications, including guidelines for scanning QR codes safely.
• Multi-Factor Authentication: Enforce multi-factor authentication (MFA) protocols to enhance account security and mitigate the risk of unauthorized access resulting from compromised credentials.
• Vendor Risk Management: Strengthen vendor risk management practices to minimize the impact of VEC attacks and safeguard critical supply chain relationships.

Summary

QR codes phishing represents a significant evolution in phishing tactics, exploiting familiar technology to deceive users and compromise organizational security. As cybercriminals continue to innovate and adapt, organizations must remain vigilant against emerging threats while fortifying defenses against established attack vectors like BEC and VEC.
