Google Launches New Maps Feature to Help Businesses Report Review-Based Extortion Attempts

Google Launches New Maps Feature to Help Businesses Report Review-Based Extortion Attempts

Nov 07, 2025 Data Protection / Malware
Google on Thursday said it's rolling out a dedicated form to allow businesses listed on Google Maps to report extortion attempts made by threat actors who post inauthentic bad reviews on the platform and demand ransoms to remove the negative comments. The approach is designed to tackle a common practice called review bombing , where online users intentionally post negative user reviews in an attempt to harm a product, a service, or a business. "Bad actors try to circumvent our moderation systems and flood a business's profile with fake one-star reviews," Laurie Richardson, vice president of Trust & Safety at Google, said . "Following this initial attack, the scammers directly contact the business owner, often through third-party messaging apps, to demand payment." The threat actors warn of further escalation should the victim fail to pay the fee, risking potential damage to their public rating and reputation. These ploys are seen as an attempt to coe...

Google Uncovers PROMPTFLUX Malware That Uses Gemini AI to Rewrite Its Code Hourly

Google Uncovers PROMPTFLUX Malware That Uses Gemini AI to Rewrite Its Code Hourly

Nov 05, 2025 Artificial Intelligence / Threat Intelligence
Google on Wednesday said it discovered an unknown threat actor using an experimental Visual Basic Script (VB Script) malware dubbed PROMPTFLUX that interacts with its Gemini artificial intelligence (AI) model API to write its own source code for improved obfuscation and evasion. "PROMPTFLUX is written in VB Script and interacts with Gemini's API to request specific VBScript obfuscation and evasion techniques to facilitate 'just-in-time' self-modification, likely to evade static signature-based detection," Google Threat Intelligence Group (GTIG) said in a report shared with The Hacker News. The novel feature is part of its "Thinking Robot" component, which periodically queries the large language model (LLM), Gemini 1.5 Flash or later in this case, to obtain new code so as to sidestep detection. This, in turn, is accomplished by using a hard-coded API key to send the query to the Gemini API endpoint. The prompt sent to the model is both highly speci...
Ransomware Defense Using the Wazuh Open Source Platform

Ransomware Defense Using the Wazuh Open Source Platform

Nov 04, 2025 Threat Detection / Cybercrime
Ransomware is malicious software designed to block access to a computer system or encrypt data until a ransom is paid. This cyberattack is one of the most prevalent and damaging threats in the digital landscape, affecting individuals, businesses, and critical infrastructure worldwide. A ransomware attack typically begins when the malware infiltrates a system through various vectors such as phishing emails, malicious downloads, or exploiting software vulnerabilities. Once activated, the malware encrypts files using strong cryptographic algorithms, rendering them inaccessible to the legitimate owner. The attackers then demand payment, usually in cryptocurrency like Bitcoin, in exchange for the decryption key. Modern ransomware variants have evolved beyond simple file encryption. Some employ double extortion tactics, where attackers encrypt data, exfiltrate sensitive information, and threaten to publish it publicly if the ransom is not paid. This puts pressure on victims, particularly...
