Security researchers have recently unveiled a sophisticated malware campaign that employs the ClickFix social engineering technique to disseminate information-stealing malware across both Windows and macOS platforms. This campaign highlights how cybercriminals are capitalizing on legitimate search queries for cracked software to deliver harmful payloads that compromise user credentials and sensitive information.
The infection process begins when users search for cracked or pirated software online, a well-known bait for cybercriminals. Instead of receiving legitimate results, unsuspecting victims are directed to malicious landing pages hosted on Google services such as Colab, Drive, Looker Studio, Sites, and Groups. This multi-hop infrastructure is intentionally crafted to evade conventional security measures, as administrators are typically reluctant to block Google services entirely.
Upon clicking these deceptive landing pages, users encounter fake security warnings that closely resemble authentic Cloudflare verification pages. The misleading interface instructs users to copy and paste what appears to be a verification string into their terminal. However, what victims actually execute is a malicious Base64-encoded shell command that retrieves and runs infostealer malware directly in memory, employing a fileless attack method that circumvents traditional antivirus defenses.
Overview of the ClickFix Attack Campaign
The campaign’s sophistication is evident in its operating system-specific payload delivery. Windows users are directed toward the ACR stealer, while macOS users receive the Odyssey stealer, a variant tailored for macOS. The initial payloads arrive as password-protected ZIP archives containing executable files that unleash the full capabilities of the infostealer.
Researchers have discovered that ACR not only functions as an information stealer but also acts as a loader for additional malware, including SharkClipper, a cryptocurrency clipboard hijacker that replaces copied wallet addresses with those controlled by attackers. The effectiveness of this campaign is staggering, with a documented increase of nearly 700 percent in ACR stealer logs uploaded to underground markets in May 2025 compared to the previous month, capturing 133,980 new compromised user logs in that single month.
Future Threat Predictions
The success of ClickFix can be attributed to several critical factors. Unlike traditional phishing campaigns that rely on email, these attacks emerge through organic search results and social media, effectively bypassing email security solutions. For instance, a NordVPN crack link on macOS initially redirected from Google Colab to a malicious site, but the “Download Now” button no longer triggered a second redirect.
The malicious scripts execute within browser sandboxes, rendering them invisible to most security monitoring tools. Furthermore, the commands run directly in memory, creating a clean, fileless process that eludes traditional endpoint security measures. Odyssey collects a wide array of user data, including passwords, cookies, cryptocurrency wallets, documents with specific extensions, Apple Notes, Keychain entries, and system metadata.
According to Microsoft’s 2025 Digital Defense Report, ClickFix has emerged as the most common initial access method, accounting for 47 percent of all initial access schemes. This alarming statistic signifies a broader shift in attack methodologies, as cybercriminals increasingly prioritize social engineering over technical exploits.
The implications for Windows and macOS users are profound. Once compromised, affected systems can serve as conduits for credential theft, financial data exfiltration, and further malware installations. Security experts stress the importance of never copying and executing unverified commands from unknown sources, regardless of how legitimate the prompting page may appear. Organizations must also enhance their endpoint detection and response (EDR) capabilities, as this remains the last line of defense against fileless ClickFix attacks that slip past traditional security tools.
