Learn about how to protect yourself and your business from the latest evolution in phishing attacks.
Every day, hackers and nefarious actors are launching attacks on data infrastructure – attempting to probe weaknesses and steal sensitive information.
An early iteration of hacking included the “phishing” attack, which involved luring users to click on a malicious link or open an infected attachment. However, as security measures have improved and people become more aware of these attacks, hackers have had to evolve their tactics.
One emerging threat that's gaining traction is "
" - a clever combination of QR codes and phishing. This technique is particularly dangerous because it bypasses many traditional email security measures – and can be easily executed with a simple sticker or poster.
What Is Quishing
Quishing, or QR code phishing, is one of the more sophisticated (yet simple) social engineering attacks that uses QR codes to deceive recipients into visiting malicious websites.
QR codes have been around for a while, but really came into prominence during the COVID-19 pandemic as a way to make contactless payments and access menus at restaurants. They’ve come to hold the same place in business as barcodes – allowing you to scan and access information quickly and accurately.
But hackers have found a way to exploit this technology for their own malicious purposes. By placing a QR code in an email, unsuspecting victims can easily scan it and be directed to a fake website or prompted to enter personal information.
This method is especially dangerous because many people trust QR codes and assume they are safe.
How Does Quishing Work in Emails?
Email Quishing is a unique form of phishing, using QR codes as the bait. It typically starts with a malicious email containing a QR code image. The email will often be disguised as a legitimate message from a trusted source, such as a bank or company.
- The Lure:
Attackers send emails that appear to be from trusted sources, such as HR departments, financial institutions, or well-known brands.
- The Hook:
Instead of including a suspicious link, the email contains a QR code with instructions on how to scan it for important information.
- The Trap:
When scanned, the QR code directs the victim to a fake website designed to steal credentials or personal information.
Once the victim enters their information, the attackers can use it for identity theft or financial fraud.
This type of attack often targets busy professionals who may not have time to carefully inspect every email they receive. The use of QR codes adds a sense of legitimacy and urgency, making it more likely for someone to fall for the scam.
Why Quishing is Dangerous
- Bypasses Email Security:
Most email security tools can't effectively scan or block QR codes, making this attack vector particularly stealthy.
- Exploits Mobile Vulnerabilities:
Users often scan QR codes with their personal mobile devices, which may have fewer security measures than corporate computers.
- Creates a False Sense of Security:
Many people assume QR codes are inherently safe, lowering their guard against potential threats.
- Difficult to Detect:
Unlike traditional phishing emails, there are no visible suspicious links for users to scrutinize.
Quishing & Executives
One element that has stood out has been how email quishing attacks target executives at companies more than any other type of employee. Recent research indicates that 27% of QR code attacks in the fourth quarter were fraudulent notifications regarding MFA, and about 21% were deceptive alerts concerning a shared document.
Why the focus on executives? With two and multi-factor authentication now widespread, attackers are adjusting their tactics to try and obtain single-use codes from high-level executives.
By targeting individuals in leadership positions, hackers can potentially gain access to sensitive company information or networks. Plus, many executives have busy schedules and receive a large volume of emails daily. This can make it easier for them to overlook suspicious messages or not take the necessary precautions when interacting with QR codes.
Tips for Protecting Your Business from Quishing
Employee Education
Conduct regular training sessions to teach staff about the dangers of quishing and how to identify suspicious emails. Rather than only relying on tools and software to block attacks, educate your employees to be the first line of defense against quishing attempts.
Enable Multi-Factor Authentication (MFA)
While not foolproof, MFA adds an extra layer of security even if credentials are compromised. Again, knowing how to differentiate between a quishing attack and a legitimate login request is key.
Establish Clear Policies
Create guidelines for handling QR codes in business communications and encourage employees to verify the sender through other channels before scanning any codes. Emails, in particular, should include a warning to never enter personal information through a QR code.
Keep Software Updated
Ensure all devices, especially mobile ones, have the latest security patches and updates installed. If you can stop cyberattacks before they happen, it is a much easier and more effective solution than trying to recover from one.
