Quishing, short for "QR code phishing," involves using QR codes to deceive victims. Here's how it works:
Cybercriminals generate seemingly harmless QR codes that lead to fraudulent websites or initiate downloads of malicious software. These malicious QR codes can be distributed via emails, social media, printed materials, or even by placing stickers over legitimate QR codes in public spaces.
When someone scans the malicious QR code, they are directed to a deceptive website. The site may appear legitimate, offering discounts, special deals, or other enticing content. However, victims are unwittingly prompted to provide sensitive information, such as login credentials or financial details. In some cases, malware is downloaded, compromising the victim's device and network.
One notable trend involves the use of crypto ATMs and QR codes. The FBI has reported an increase in scammers instructing victims to use physical crypto ATMs for payment transactions. Fraudsters manipulate victims into making payments and guide them to cryptocurrency ATMs. The given QR code automatically fills in the recipient's address, making the process seem legitimate.
Be Cautious: Only scan QR codes from trusted sources. Avoid scanning random codes in public places. Double-check the URL before providing any information on a website. If something seems too good to be true, it probably is.
Use a QR Code Scanner App: Opt for a reputable QR code scanner app that checks URLs for authenticity. Some apps provide warnings if a code leads to a suspicious site.
Stay Informed: Keep up with security news and trends. Educate yourself and your team about the risks of quishing.
QR codes—those pixelated portals to convenience—can also harbor danger. As you scan, tread cautiously. Verify sources, question context, and guard your trust. Remember, not all codes lead to safety.
The codes, which are a digital jumble of white and black squares that are frequently used to record URLs, are apparently commonplace; they may as well be seen, for example, on menus at restaurants and retail establishments. The Federal Trade Commission cautioned on Thursday that they could be dangerous for those who aren't cautious.
According to a report by eMarketer, around 94 million US consumers have used QR scanner this year. The number is only increasing, with around 102.6 million anticipated by 2026.
As per Alvaro Puig, a consumer education specialist with the FTC, QRs are quite popular since there are endless ways to use them.
“Unfortunately, scammers hide harmful links in QR codes to steal personal information,” Puig said.
The stolen data can be misused by threat actors in a number of ways: According to a separate report by FTC, the identity thieves can use victim’s personal data to illicitly file tax returns in their names and obtain tax refunds, drain their bank accounts, charge their credit cards, open new utility accounts, get medical treatment on their health insurance, and open new utility accounts.
In some cases, criminals cover the legitimate QR codes with their own, in places like parking meters, or even send codes via text messages or emails, luring victims into scanning their codes.
One of the infamous tactic used by scammers is by creating a sense of urgency in their victims. For example, they might suggest that a product could not be delivered and you need to reschedule or that you need to change your account password because of suspicious activity.
“A scammer’s QR code could take you to a spoofed site that looks real but isn’t,” Puig wrote. “And if you log in to the spoofed site, the scammers could steal any information you enter. Or the QR code could install malware that steals your information before you realize it.”
According to FTC, some of the measures one can follow to protect themselves from scams are:
Apple has taken another significant step towards improving the security of its messaging platform, iMessage. The introduction of Contact Key Verification adds an extra layer of security to iMessage conversations, protecting user data and privacy. In this article, we will explore what Contact Key Verification is and why it matters.
iMessage is a popular messaging platform known for its end-to-end encryption, which ensures that only the sender and the recipient can read the messages. With the new Contact Key Verification feature, Apple is making iMessage even more secure by allowing users to verify the identity of the person they are messaging with.
Contact Key Verification uses public key cryptography to establish a secure connection between the sender and receiver. Each iMessage user has a unique public key, which is stored on Apple's servers. When a user sends a message, their public key is used to encrypt the message. The recipient's device then uses their private key to decrypt and read the message. This ensures that only the intended recipient can access the content.
But what Contact Key Verification does differently is that it allows users to confirm that the public key used for encryption belongs to the person they intend to communicate with. This extra layer of verification prevents man-in-the-middle attacks, where an attacker intercepts and decrypts messages meant for someone else.
The implementation of Contact Key Verification is simple. Users can access the feature by tapping on the contact's name or picture in the chat. They can then view the contact's key and verify it through various methods like scanning a QR code or comparing a series of numbers with the contact in person.
This additional security feature is essential in today's digital landscape, where data breaches and cyberattacks are increasingly common. It ensures that even if someone gains access to your device, they cannot impersonate you or read your messages without proper verification.
Apple's commitment to user privacy is evident in this move. By giving users control over their message security, they are ensuring that iMessage remains one of the most secure messaging platforms available. Moreover, the public key infrastructure used in Contact Key Verification is a proven method for securing digital communications.
Leading cybersecurity firms have reported a startling 587% increase in QR code-based phishing assaults in recent times. This concerning pattern demonstrates how fraudsters are changing their strategies to take advantage of people's confidence in QR codes for a variety of objectives.
The research findings were based on data collected from millions of endpoints using HP Wolf Security:
Since October 2022, HP has witnessed QR code “scan scam” campaigns almost daily. These frauds persuade users to scan QR codes with their mobile devices while connected to their PCs, potentially exploiting the lack of phishing protection and detection on such devices. Users can access fraudulent websites that request credit and debit card information by scanning QR codes. Examples from Q4 include phishing attempts that pose as parcel delivery services seeking money.
38% Rise in Malicious PDF Attachment:
The recent assaults avoid web gateway scanners by using embedded images that link to malicious ZIP files that are encrypted. The PDF instructions fool the user into providing a password to unpack a ZIP file, allowing QakBot or IcedID malware to gain access to systems unauthorization and serve as beachheads for ransomware.
42% of Malware was Delivered Inside Archives Files Like ZIP, RAR, and IMG:
Archives have gained a whooping 20% rise in popularity since Q1 2022, as threat actors use scripts to execute their payloads. In contrast, 38% of malware is distributed via Office documents like Microsoft Word, Excel, and PowerPoint.
Alex Holland, Senior Malware Analyst at HP Wolf Security threat research team said, “We have seen malware distributors like Emotet try to work around Office’s stricter macro policy with complex social engineering tactics, which we believe are proving less effective. But when one door closes, another opens – as shown by the rise in scan scams, malvertising, archives, and PDF malware.”
“Users should look out for emails and websites that ask to scan QR codes and give up sensitive data, and PDF files linking to password-protected archives,” added Holland.
HP researchers also discovered eight malware families imitated in 24 popular software projects in Q4's malvertising efforts, as compared to just two such operations in Q3's. The attacks rely on people clicking on search engine adverts that take them to malicious websites that resemble legitimate websites nearly identity.
Dr. Ian Pratt, Global Head of Security for Personal Systems, HP says “While techniques evolve, threat actors still rely on social engineering to target users at the endpoint.”
“Organizations should deploy strong isolation to contain the most common attack vectors like email, web browsing and downloads. Combine this with credential protection solutions that warn or prevent users from entering sensitive details onto suspicious sites to greatly reduce the attack surface and improve an organization’s security posture,” concludes Pratt.
QR codes - the little Digi squares, an effective tool for contactless transactional activities especially during the Covid-19 pandemic. Quick Response (QR) codes were originally developed back in the mid-nineties for utilization in the Japanese auto-making industry as a swift, machine-readable technique to reserve information regarding a specific item, whether for production, inventory, or eventual scale.
