Digital Event Horizon
The ClickFix scam has already infected countless computers worldwide, leaving many users vulnerable to further attacks. This article provides an in-depth look at this new and deadly form of malware infestation, highlighting its unique characteristics and the importance of cybersecurity awareness among potential targets.
ClickFix is a new form of malware that has infected countless computers worldwide. The scam campaigns use emails or WhatsApp messages from a hotel account with pending registration information to trick victims into downloading malware. Once clicked, the malware requests users to copy and paste a string of text, which downloads and installs credential-stealing malware. The malware can bypass some endpoint protections and is often delivered through malvertising or search results from Google. Awareness and cybersecurity measures are essential in protecting against ClickFix scams, as malware can be difficult to detect and defend against.
The world of cybersecurity is constantly evolving, with new threats emerging every day to challenge even the most seasoned security professionals. In recent months, a particularly insidious form of malware has gained attention from experts in the field, known as ClickFix. This scam, which has already infected countless computers and left many users vulnerable to further attacks, is a prime example of the ever-present threat of online scams.
ClickFix campaigns begin with emails or WhatsApp messages sent from the account of a hotel that the target has a pending registration with, referencing the correct registration information. In some cases, the attackers also use search results from Google to send the URL directly to the user's device. Once the mark accesses the malicious site referenced, it presents a CAPTCHA challenge or other pretext requiring user confirmation. The user receives an instruction to copy a string of text, open a terminal window, paste it in, and press Enter.
Once entered, the string of text causes the PC or Mac to surreptitiously visit a scammer-controlled server and download malware. Then, the machine automatically installs it—all with no indication to the target. With that, users are infected, usually with credential-stealing malware.
Security firms say ClickFix campaigns have run rampant, driven by factors such as the lack of awareness among potential targets, links coming from known addresses or in search results, and the ability to bypass some endpoint protections. The primary piece of malware installed in these campaigns is a credential-stealer tracked as Shamos. Other payloads included a malicious cryptocurrency wallet, software for making the Mac part of a botnet, and macOS configuration changes to allow the malware to run each time the machine reboots.
The ClickFix campaign highlights that leveraging malvertising and the one-line installation-command technique to distribute macOS information stealers remains popular among eCrime actors. Promoting false malicious websites encourages more site traffic, which will lead to more potential victims. The one-line installation command enables eCrime actors to directly install the Mach-O executable onto the victim’s machine while bypassing Gatekeeper checks.
The attacks can also be effective given the lack of awareness. Many people have learned over the years to be suspicious of links in emails or messengers. In many users' minds, the precaution doesn't extend to sites that instruct them to copy a piece of text and paste it into an unfamiliar window. When the instructions come in emails from a known hotel or at the top of Google results, targets can be further caught off guard.
Many families are gathering in the coming weeks for various holiday dinners, making ClickFix scams worth mentioning to those family members who ask for security advice. Microsoft Defender and other endpoint protection programs offer some defenses against these attacks, but they can, in some cases, be bypassed. That means that, for now, awareness is the best countermeasure.
In conclusion, ClickFix is a new and deadly form of malware infestation that has already infected countless computers worldwide. Its unique characteristics make it particularly challenging to detect and defend against, and its widespread use highlights the importance of cybersecurity awareness among potential targets. By understanding the tactics used by these attackers, we can better protect ourselves against these types of attacks.
