A new kind of digital scam is spreading across the UK, where criminals trick people using fake QR codes. This type of scam is called “quishing,” and it has been growing quickly. In 2023, there were over 1,300 reports of this scam, compared to only 100 cases in 2019, showing just how fast it's increasing.
How These Scams Work
Scammers take advantage of everyday places where QR codes are used for payments or information. This includes locations like parking spots or restaurant tables where you scan codes to pay or view menus. What these scammers do is cover the real QR codes with fake ones that they control.
When someone scans the fake code, it sends them to a fake website. The site may ask them to enter payment details, thinking it's a normal payment page. In some cases, clicking the link may even install harmful software on the person’s phone without them knowing.
Why It’s Hard to Notice
These scams can be hard to detect. Unlike large frauds that take big sums of money at once, these scams often take small amounts over time, making it less likely for someone to notice. The charges might look like monthly fees or parking payments, so they often go unnoticed.
Cyber experts say that what makes this scam dangerous is how real the fake websites appear. The links that come up after scanning look just like real ones, so people don’t think twice before entering their card numbers or other personal information.
What You Can Do to Stay Safe
Here are some simple steps to protect yourself:
1. Only scan QR codes that you trust. If the code looks tampered with or placed unevenly, avoid using it.
2. Never enter sensitive information like card numbers on a website you reached through a QR code unless you’re sure it’s safe.
3. Before submitting any details, double-check the website’s name or URL for spelling errors or anything unusual.
4. Use a reliable security app on your phone that can detect harmful links or files.
QR codes were created to make daily tasks faster and more convenient. But now, scammers are misusing them to steal people’s information and money. As these scams become more common, the best defense is to be alert and avoid scanning any QR code that looks even slightly suspicious.
Cybercriminals have found a new way to trick Windows users into downloading harmful software by disguising malware as a CAPTCHA test. A recent investigation by security researchers revealed that attackers are using this method to install infostealer malware, which secretly collects sensitive data from infected computers.
How the Scam Works
The attack begins when a user visits a compromised website and encounters what appears to be a routine CAPTCHA verification. These tests are usually used to confirm that a visitor is human, but in this case, clicking on it unknowingly triggers a harmful command.
Instead of simply verifying the user’s identity, this fake CAPTCHA executes a hidden script that launches a multi-step infection process. The malware then installs itself and starts collecting sensitive information like usernames, passwords, and banking details.
Step-by-Step Breakdown of the Attack
1. Fake CAPTCHA Displayed: The user sees what looks like a normal CAPTCHA test.
2. PowerShell Command Executed: Clicking on the CAPTCHA activates a hidden script that runs harmful commands.
3. Additional Malicious Code Downloaded: The script retrieves more files, which help the malware spread without detection.
4. Final Infection: The malware, such as Lumma or Vidar, is installed and begins stealing personal data.
How Attackers Evade Detection
Hackers use several techniques to keep their malware hidden from security software:
Obfuscation: The malware code is made more complex to avoid being detected by antivirus programs.
Multiple Layers of Encryption: Attackers scramble the malware’s code so that security tools cannot recognize it.
Bypassing Security Measures: The script manipulates Windows settings to prevent detection and removal.
In some cases, the malware uses a special trick called XOR encryption to disguise itself. Some versions even include commands that trick Windows security tools into believing the malware is safe.
How to Protect Yourself
To avoid falling victim to this scam, follow these precautions:
1. Be Wary of Suspicious CAPTCHAs: If a CAPTCHA test appears unusual or asks for unexpected actions, do not interact with it.
2. Stay on Trusted Websites: Avoid unknown or unverified sites, as they may be compromised.
3. Keep Your System Updated: Install the latest security updates for Windows and your antivirus software.
4. Use Reliable Security Tools: A strong antivirus program can help detect and block suspicious activity.
5. Enable Browser Protections: Modern web browsers offer security features that warn against unsafe websites — keep them turned on.
This deceptive CAPTCHA scam is a reminder that cybercriminals are always coming up with new ways to infect devices and steal personal data. By staying alert and following basic security practices, users can reduce their chances of being targeted by such attacks.
A new scam is targeting top business leaders in the United States, where criminals are sending letters demanding large ransom payments. Unlike typical ransomware attacks that involve hacking into computer systems, this scheme relies on physical mail. The letters claim that hackers have stolen company data and will leak it unless a ransom of $250,000 to $500,000 is paid. However, cybersecurity experts believe this is a fraud, with no actual hacking involved.
How the Scam Works
Investigators from the GuidePoint Research and Intelligence Team (GRIT) discovered that several companies have received these ransom letters through the US Postal Service (USPS). The letters are addressed to high-level executives and claim to be from the BianLian ransomware group, a known cybercriminal organization.
The message states that the company's confidential information has been stolen and will be exposed unless the demanded payment is made within ten days. To make the threat appear real, the letter includes a Bitcoin wallet address and a QR code that links directly to it. Some letters also provide links to BianLian’s dark web site to add legitimacy to the claim.
Despite these details, security analysts have found no proof that any actual data theft has occurred. The scam relies on fear and deception, hoping that executives will panic and send money.
Why Experts Believe the Threat Is Fake
Cybersecurity specialists have carefully examined multiple cases of this scam and found no signs of hacking or data breaches. The companies targeted in this scheme have not reported any unusual activity or unauthorized access to their systems. This strongly suggests that the criminals behind the letters are only pretending to be the BianLian ransomware group.
The FBI has confirmed that these letters are part of a fraud campaign and do not represent a real cyberattack. Many of the envelopes are marked as "Time Sensitive" to create urgency, and some even list a return address in Boston, Massachusetts, which appears to be another false detail.
Since there is no actual ransomware attack, businesses do not need to take technical action like removing malware or restoring stolen files. The main risk comes from executives believing the scam and paying the ransom.
What to Do If You Receive One of These Letters
If your company receives a similar ransom demand, take the following precautions:
1. Check Your Systems for Security Issues – Ensure that company networks are protected and that there are no signs of hacking or data leaks. Keeping cybersecurity measures updated is always important.
2. Do Not Send Any Money – These threats are fake, and paying the ransom will only encourage further scams.
3. Report the Scam – Contact law enforcement and inform the nearest FBI field office about the letter. Complaints can also be filed with the Internet Crime Complaint Center (IC3).
4. Inform Key Personnel – Let executives and employees know about this scam so they can recognize and ignore similar fraud attempts in the future.
This scam is a reminder that cybercriminals do not always rely on advanced hacking techniques. Sometimes, they use old-fashioned methods like physical mail to create fear and manipulate victims into paying. While real ransomware attacks remain a serious concern, this particular scheme is based on false claims.
Companies should stay informed and take precautions to avoid falling victim to these types of fraud. Being aware of such scams is the best way to protect against them.
