Hackers Abuse Google Sheets to Hijack Crypto Wallet Addresses in ClickFix Attacks
Cisco Talos details a crypto-theft ClickFix campaign abusing Google Sheets to swap wallet addresses, with about $10,000 in observed Bitcoin losses.
Cisco Talos tracks a ClickFix-style campaign that tricks cryptocurrency traders into pasting JavaScript into Chrome's address bar or a Tampermonkey extension, promising fake bonuses on SwapZone and SimpleSwap. The loader pulls obfuscated JavaScript from cells in a public Google Sheet via the Visualization API, then behaves like a web skimmer, rewriting deposit addresses on screen, in web responses, and in the clipboard. Researchers counted 49 attacker-controlled Bitcoin addresses, with 24 receiving a combined 0.159 BTC, roughly $10,000, by early August 2026. A Tampermonkey variant re-injects the payload on every return visit, giving the attackers persistence despite takedown efforts.

Risky Bulletin: Ukraine's top prosecutor resigns amid scam call center scandal
Ukraine's top prosecutor Ruslan Kravchenko resigned after NABU arrested a deputy for taking bribes protecting scam call centers running fake investment platforms.
Ukraine's anti-corruption bureau NABU arrested Serhiy Kropyva, Deputy Head of International Cooperation at the Prosecutor General's Office, alleging officials took monthly protection fees from a network of 100-500 scam call centers luring victims into fake investment platforms, with bribes reportedly growing from $700,000 to $3.5 million per month. Prosecutor General Ruslan Kravchenko resigned on Monday, calling it a political decision, while Kropyva was fired with bail set at 120 million hryvnias ($2.7 million) and over 100 call centers shut down in the past month. The newsletter also briefly covers a cyberattack crippling more than 80 Luxembourg medical practices via payment vendor BMS Engineering, ShinyHunters' claimed theft of 200,000 Florida DMV driver records, a cyberattack on the American Meteor Society, and school closures in Springfield, Massachusetts.

ClickFix moves into the browser: Cryptocurrency theft with Google-hosted C2
Talos tracks a crypto-theft campaign abusing the Google Visualization API for C2, using browser-based ClickFix lures to inject web-skimmer JavaScript.
Criminal actors convinced targets to paste JavaScript into Chrome's address bar or install it in the Tampermonkey extension, injecting a web skimmer into sessions on two cryptocurrency trading websites; Tampermonkey also provides persistence. Since March 2026 the campaign retrieved obfuscated scripts via the Google Visualization API from public Google Sheets documents, hooking the fetch API and replacing cryptocurrency deposit addresses in responses and the clipboard. Lures pose as leaked reports of a nonexistent API flaw at cryptocurrency swap services and spread via Telegram, DarkForums, and paste sites since early October 2025. Talos warns the legitimate-service-abuse techniques could enable wider supply-chain attacks on e-commerce and customer-facing systems.
