What is Quishing: Protect yourself from QR Phishing

As cybersecurity threats evolve, you must stay vigilant against new forms of attack. One emerging threat you need to be aware of is quishing, a sophisticated variation of phishing that exploits QR codes to deceive victims. Unlike traditional phishing emails, quishing definition is that it leverages QR codes’ widespread use and convenience to lure you into scanning malicious codes. These attacks can compromise your personal information financial data, or even grant attackers access to your devices. Understanding how quishing works and learning to identify potential threats is crucial for protecting yourself in today’s digital landscape. This article will explore the mechanics of quishing attacks and provide essential tips to safeguard against this growing cybersecurity risk.

What is Quishing?

Quishing, a portmanteau of “QR code” and “QR phishing,” is a sophisticated cyber attack that exploits the increasing popularity of QR codes. In this scheme, malicious actors create fraudulent QR codes that, when scanned, direct unsuspecting users to phishing websites or initiate malware downloads. Unlike traditional phishing methods that rely on deceptive emails or text messages, quishing capitalizes on QR codes’ perceived trustworthiness and convenience. This technique is also called QR phishing attack.

These malicious QR codes can be distributed through various channels, including physical locations, digital advertisements, or even tampered legitimate codes. When scanned, they may lead to fake login pages, prompt users to download malicious apps, or collect sensitive information. The danger lies in the difficulty of distinguishing between legitimate and malicious QR codes, making quishing a particularly insidious form of cyber threat.

How does QR code phishing Work?

QR code phishing, or “quishing,” exploits the convenience of QR codes to lure unsuspecting victims into cybertraps. Attackers create malicious QR codes that, when scanned, redirect users to fraudulent websites or automatically download malware. These deceptive codes may appear in emails, on posters, or even as stickers placed over legitimate QR codes.

Common quishing tactics

• Impersonating trusted brands or services
• Promising enticing offers or discounts
• Creating a sense of urgency to scan the code
• Disguising malicious links as harmless QR codes

When scanned, these codes can lead to phishing sites that steal personal information, install malware, or initiate unauthorized financial transactions. As QR codes become more prevalent in daily life, users must remain vigilant and verify the source before scanning any code.

Initial Contact

Scammers distribute fake QR codes through various channels, including emails, text messages, or even physical posters in public spaces. The accompanying message often creates a sense of urgency or curiosity to entice victims to scan the code.

Redirection and Data Collection

Once scanned, the QR code directs users to a convincing but fake website. This site may mimic a legitimate organization, prompting users to enter sensitive information like login credentials or financial details.

Data Exploitation

With the collected data, cybercriminals can carry out identity theft, financial fraud, or gain unauthorized access to personal accounts, potentially causing significant harm to the victim.

Protecting Yourself from Quishing Attacks

To safeguard against quishing attacks, stay vigilant and adopt proactive measures.

• First, always verify the sender’s identity before interacting with QR codes in emails or messages.
• Hover over links to check their destination before clicking.
•  Enable multi-factor authentication on all accounts to add an extra layer of security.
• Watch for suspicious QR codes in emails, text messages, or social media posts.
• Be wary of unsolicited messages urging you to scan a QR code, especially if they create a sense of urgency or offer enticing rewards.
• Keep your devices and applications updated with the latest security patches.
• Use a reputable antivirus program and enable its real-time protection features.
• Be cautious when scanning QR codes in public places, as they may be tampered with or replaced by malicious actors.
• Stay informed about the latest phishing techniques and educate your colleagues and family members.
• Remember, legitimate organizations rarely ask for sensitive information through QR codes. When in doubt, contact the purported sender directly through official channels to verify the request’s authenticity.

Quishing attack examples

Quishing attacks can take various forms, exploiting users’ trust in QR codes.

• One common scenario involves attackers placing malicious QR codes on physical surfaces, such as posters or flyers. When scanned, these codes redirect victims to phishing websites that mimic legitimate services.
• Another example is the use of compromised email accounts to send QR codes that appear to come from trusted sources. These codes may lead to fake login pages designed to steal credentials.
• Some cybercriminals even manipulate digital advertisements, replacing genuine QR codes with malicious ones. This tactic can be particularly effective on social media platforms or online marketplaces.

In more sophisticated attacks, hackers might create fake apps that generate malicious QR codes, tricking users into scanning them under the guise of accessing exclusive content or deals.

How to Identify Quishing Messages?

Recognizing quishing attempts requires vigilance and attention to detail.

Red Flags to Watch For

• Unexpected QR codes from unknown senders
• Pressure to act quickly or face consequences
• Requests for personal or financial information
• Poor grammar or spelling errors in the message
• URLs that don’t match the claimed organization

When in doubt, contact the purported sender directly through official channels to confirm the message’s legitimacy. Remember, legitimate organizations rarely request sensitive information via QR codes.

Notable Rise in Quishing Attacks

Quishing attacks have seen a dramatic rise in recent years, catching many organizations off guard. According to cybersecurity experts, there was a 500% increase in quishing attempts between 2021 and 2024. This surge highlights the growing sophistication of cybercriminals in exploiting QR code technology.

•  Alarmingly, 58% of users admit to scanning QR codes without verifying their source or destination. This lack of caution has led to a 300% uptick in successful quishing breaches, resulting in an estimated $2.1 billion in financial losses globally in 2022 alone.
• QR code phishing, or “quishing,” has significantly risen in recent years. In 2022, the FBI warned of a surge in QR code scams targeting unsuspecting victims. One notable incident involved a parking meter scam in major U.S. cities, where fraudsters replaced legitimate QR codes with malicious ones, redirecting payments to scammers’ accounts.
• Corporate environments are particularly vulnerable, with 67% of businesses reporting at least one quishing incident in the past year.
• Statistics from Quishing indicate a significant increase in QR code phishing emails from June to August 2023. There were 8,878 reported incidents during this period, signaling a concerning shift in cybercriminal tactics. The peak of this trend occurred in June, with 5,063 reported cases of QR code phishing attacks.
• These statistics highlight a concerning lack of detection and reporting of these attacks. Only 36% of these incidents were accurately identified and reported by the recipients. This gap in security awareness and preparedness leaves many vulnerable to the risks associated with deceptive QR phishing.
• Further analysis reveals that certain industries are more frequently targeted by these Quishing campaigns. The energy sector appears to be the most vulnerable, receiving 29% of over 1,000 malware-infested phishing email QR codes.
• Additionally, the manufacturing, insurance, technology, and financial services sectors are also at high risk, indicating a strategic focus by cybercriminals on sectors they perceive as either more lucrative or vulnerable.
