Google Strengthens Chrome Defenses Against ClickFix Clipboard-Based Scams
Google has enhanced Chrome protection against ClickFix attacks, in which users are tricked into manually executing malicious commands copied from the clipboard. The update targets scams that impersonate technical support and persuade victims to paste harmful scripts into tools such as PowerShell.
The new mechanisms operate when Enhanced Protection mode in Safe Browsing is enabled. Chrome now recognizes when a suspicious script is copied to the clipboard and can display a warning before the command is executed. The browser sends the command for analysis after stripping personal data; if the check flags it as dangerous, the user receives an alert.
ClickFix attacks rely on a deceptive technique: the site displays a fake error and instructs the user to copy a command, open the system console, and run it. The actual text placed in the clipboard often differs from what is shown on the page, allowing attackers to load malware while bypassing normal download scanning.
In parallel, Google moved detection of fraudulent pages from a local Gemini model to a server-side implementation. The system now searches for fake tech-support pages, counterfeit antivirus software, and bogus browser-update sites. Text sent for analysis is not stored and is not used to train models.
Additional warnings have been introduced for suspicious sites, while known dangerous pages continue to trigger the familiar red interstitial screen.

Excerpt from Black Hat Rust Translation Details Chapter 9 on Phishing via WebAssembly and Social Engineering
A detailed excerpt from Chapter 9 of the Russian translation of Black Hat Rust has been published on Habr.com. The chapter focuses on phishing attacks that leverage WebAssembly when traditional technical vulnerabilities cannot be exploited due to lack of skills, team resources, or time. It explains social engineering principles based on Aristotle's Rhetoric, covering Ethos for building credibility, Pathos for creating emotional connections through storytelling, and Logos for logical justification of requests. The post emphasizes that human targets are often more vulnerable than infrastructure and that persuasion techniques have remained consistent for over 2000 years. The translator notes that code examples are preserved without modernization to serve as a lesson in verifying exploits independently, referencing common issues on platforms like Exploit-DB. The full chapter and previous translations are available in the associated GitHub repository.
Lost Control Series Highlights Realistic Social Engineering Attacks Disguised as Workplace Documents
A new micro-film in the Lost Control series demonstrates how employees can be tricked into compromising their organizations by opening files that appear to be routine work documents such as layoff lists, internal notices, or tax inspection alerts. The six-minute video recreates authentic attack vectors including phishing emails, fake download sites, bundled legitimate software packages, and phishing websites, as documented in five recent cases released by China's Ministry of Public Security Cyber Security Bureau. These attacks succeed because they mimic normal business communications rather than obvious malware delivery methods. The producers recommend sharing the film internally, reviewing work group messages from the past 30 days for suspicious attachments labeled as personnel lists or official notices, and verifying any such files before opening them. Organizations whose annual security training lacks measurable improvement in employee detection rates are invited to contact Allsec for assessment. Victims who have already clicked links or transferred funds are advised to call the national anti-fraud hotline 96110 immediately. The content is AI-generated with artistic modifications based on publicly reported incidents.
Students Recruited as Money Mules: How Scammers Target Youth with Fake Jobs, Gaming Lures and Sextortion
Russian students and schoolchildren are increasingly targeted by fraudsters offering easy part-time work, free in-game currency, or urgent academic verifications that lead to money mule schemes or account takeovers. Criminals exploit young people's need for income, interest in games like Roblox, and lack of experience with financial verification processes. Common tactics include fake job postings that turn participants into droppers under Article 187 of the Russian Criminal Code, phishing calls impersonating university staff, and malicious game mods for Minecraft or Brawl Stars. Victims risk criminal liability, banking restrictions from the Bank of Russia, and sextortion using AI-generated images. The report details seven major scam types and provides concrete protection steps including two-factor authentication and the Take It Down service.
OTP Bank Details How It Detects Professional Cashback Hunters and Card Rental Schemes
OTP Bank’s head of information security control, Alexander Shirokov, explains where legitimate use of cashback programs ends and abuse begins. The bank distinguishes rational use of tariffs from deliberate schemes created solely to extract maximum bonuses. Professional cashbackers who study rules in detail, rent cards, or share privileges are monitored through behavioral analytics and ML models. Such activity creates concentrated load on loyalty programs and can force banks to adjust conditions. The institution stresses that automatic systems are only the first layer and analysts review borderline cases to avoid penalizing ordinary customers.
