Security researchers reported an active macOS social-engineering campaign that abuses Google Search sponsored results and Google-hosted content (notably docs.google.com, and also business.google.com) to funnel users to forged Apple Support-like pages and other lookalike content (including Medium posts). The pages instruct victims—often searching for “mac cleaner” tools or macOS maintenance tasks like clearing cache—to copy/paste an obfuscated Base64 command into Terminal, which then downloads and executes a follow-on script with the user’s permissions.
Once executed, the payload can enable remote access and data theft, including harvesting sensitive files and SSH keys, and may also deploy additional malware or cryptomining. One report ties the activity to delivery of the AMOS (aka SOMA) stealer, which was observed creating artifacts such as .agent (AppleScript used to run theft), .mainHelper (Mach-O binary), and .pass (password stored in plaintext), and attempting to access user data including Documents and Notes. Researchers also noted the apparent use of compromised, Google-verified advertiser accounts to place the malicious ads, helping the campaign bypass ad-platform trust checks.

4 events from the most recent confirmed update back to the earliest known activity.
After identifying the abuse of Google Ads and Google-hosted properties, MacKeeper reported the malicious advertisements to Google for takedown. The campaign appeared to rely on compromised Google-verified advertiser accounts to evade platform trust controls.
Analysis of the payload showed the campaign delivered AMOS, also known as SOMA, a macOS infostealer fetched via curl and executed in a way that bypassed normal quarantine protections. The observed sample immediately began staging stolen data, including files from the Documents folder, and dropped hidden components in the victim's home directory, including a launcher, a Mach-O binary, and a file containing the victim's password in plaintext.
The campaign's lure pages presented bogus disk-cleaning instructions that told users to paste a Base64-obfuscated command into macOS Terminal. Running the command downloaded and executed a script with the user's privileges, enabling follow-on actions such as remote access, data theft, SSH key extraction, additional malware deployment, or cryptomining.
MacKeeper researchers discovered a phishing and malware delivery campaign on 2026-01-26 that used Google Ads to target macOS users searching for "mac cleaner" and similar tools. The ads redirected victims to fake Apple Support pages, including some hosted on Google-owned services, to make the scam appear legitimate.

Threat actors are running a **ClickFix**-style social-engineering campaign that abuses **Google sponsored search results** to funnel macOS users to malicious content hosted on legitimate platforms, including **Anthropic Claude public artifacts** (`claude.ai`) and **Medium** pages impersonating trusted sources (e.g., Apple Support). The lures target common search queries such as “online DNS resolver,” “macOS CLI disk space analyzer,” and “HomeBrew,” then instruct victims to paste and run Terminal commands that decode/execute payloads (e.g., `echo "..." | base64 -D | zsh` or `curl ... | zsh`). Researchers (Moonlock Lab/MacPaw and AdGuard) reported that the malicious Claude artifact accumulated **~12,300 to 15,600 views**, indicating significant exposure (reported as **10,000+** and **15,000+** potential victims across coverage). The payloads deliver macOS information-stealing malware, including **MacSync**, which collects data such as **Keychain credentials, browser data, and cryptocurrency wallet files**. Reported tradecraft includes downloading and executing a shell script, using an AppleScript component for theft, staging stolen data into `/tmp/osalogging.zip`, and exfiltrating via HTTP POST to attacker infrastructure (e.g., `a2abotnet[.]com/gate`, with C2 paths like `a2abotnet[.]com/dynamic`). The malware attempts to blend in by spoofing legitimate macOS browser User-Agent strings and includes retry logic for large/chunked uploads, then removes staging artifacts to reduce forensic traces.

A sophisticated cybercriminal campaign has been identified targeting macOS users, particularly developers, by leveraging fake download portals that impersonate trusted platforms such as Homebrew, LogMeIn, and TradingView. The attackers have registered over 85 domains that closely mimic the legitimate sites of these popular tools, using convincing branding and user interfaces to deceive visitors. These malicious domains are promoted through Google Ads, ensuring that they appear prominently in search results and increasing the likelihood that unsuspecting users will visit them. Once on the fake sites, users are instructed to copy and execute a curl command in their Terminal, which initiates the download and installation of infostealing malware. The primary payloads delivered in this campaign are AMOS (Atomic macOS Stealer) and Odyssey Stealer, both of which are capable of harvesting sensitive information such as system details, browser data, and cryptocurrency credentials from infected machines. The campaign employs advanced social engineering tactics, including clipboard manipulation and command obfuscation, to increase the success rate of infections. Researchers from Hunt.io have mapped the infrastructure supporting this operation, noting that the attackers reuse IP addresses and SSL certificates across multiple domains, indicating a persistent and well-organized effort. The infrastructure has been active for several years, with some IP addresses registered under personal names, suggesting a degree of operational continuity and experience. The campaign does not rely on exploiting software vulnerabilities but instead exploits user trust in widely used open-source and financial tools. The use of Google Ads as a distribution vector highlights the attackers' willingness to invest in paid advertising to reach their targets. The campaign's focus on the developer community is particularly concerning, as compromised developer systems could lead to broader supply chain risks. Security researchers have emphasized the importance of verifying download sources and being wary of unsolicited installation instructions, especially those involving Terminal commands. The ongoing nature of the campaign, with continuous adaptation of infrastructure and tactics, underscores the need for vigilance among macOS users. The discovery of this campaign began with public reports from independent researchers, which were then corroborated and expanded upon by threat intelligence teams. The scale and persistence of the operation suggest that it is likely to continue evolving, posing a significant threat to the macOS ecosystem. Organizations are advised to educate users about the risks of malvertising and to implement technical controls to block access to known malicious domains. The campaign demonstrates the increasing sophistication of social engineering attacks targeting macOS, a platform often perceived as less vulnerable than Windows.

Researchers reported multiple campaigns distributing macOS infostealers tied to the **AMOS/AtomicStealer** ecosystem, a malware-as-a-service operation that steals credentials, browser data, cryptocurrency wallets, Apple Notes, files, and **Keychain** material from macOS Catalina and newer systems on Intel, M1, and M2 devices. Earlier reporting on related macOS stealers showed operators relying on social engineering, unsigned DMG files, and password prompts to collect sensitive data, package it into archives, and exfiltrate it to command-and-control servers, with some activity also summarized to Telegram channels. More recent campaigns used **malvertising** and fake software or troubleshooting pages to lure users into running Terminal commands that fetched an AMOS variant known as **"malext"**. Investigators said the malware used obfuscated shell commands, `osascript`, quarantine removal, anti-VM and sandbox checks, and in some cases installed persistence through a LaunchDaemon and helper scripts, while also trojanizing Ledger and Trezor applications and capturing administrator passwords. Reporting also linked AMOS delivery to fake **CleanMyMac** sites and AI-themed lures, indicating operators are rapidly rotating ad accounts and adapting infection vectors to broaden theft and remote access on macOS systems.
