Following Black Hat and DEF CON conferences, a threat actor targeted attendees through X direct messages, posing as CoinDesk's VP and Head of Marketing to establish trust under the pretext of conference planning. The campaign employed a malicious Google Apps Script embedded in a Google Doc that presented ClickFix-style instructions and manual download options. The attack delivered different payloads based on the victim's operating system: macOS users received AMOS infostealer, while Windows users were infected with NetSupport RAT, a Ledger wallet implant, and a TLS-intercepting proxy. A secondary lure masqueraded as a DocSend installer to deliver additional payloads. The operation demonstrated sophisticated social engineering by leveraging trusted platforms and post-conference networking expectations.

A modular espionage framework targeting entities in Israel has evolved to incorporate sophisticated command-and-control capabilities. The framework employs DNS A-record responses to dynamically select between direct HTTPS connections and a Google Apps Script relay for each transaction, enabling operators to rotate communication channels and deployment identifiers. The communication module uses DNS infrastructure to validate and update Google Apps Script deployment IDs, while XOR encoding obfuscates command-and-control traffic. An inter-component broker coordinates framework DLL components, enabling runtime upgrades without system restarts. The infrastructure leveraged a previously expired Israeli domain, now repurposed with custom authoritative DNS servers, alongside legitimate Google services to blend malicious traffic with normal network activity.

A sophisticated phishing campaign has been identified that leverages Google Apps Script to create a false sense of security. The attack begins with an email masquerading as an invoice, containing a link to a webpage hosted on Google's trusted environment. When clicked, the link redirects to a fake invoice page, followed by a fraudulent login window designed to capture credentials. The use of Google's domain (script.google.com) adds credibility to the scam, making it more likely for users to fall victim. Once credentials are entered, they are transmitted to the attacker, and the user is redirected to a legitimate Microsoft login page to avoid suspicion. This technique demonstrates how threat actors are exploiting trusted platforms to make their attacks more convincing and effective.
