North Korean Hackers Target Brazilian Fintech with Sophisticated Phishing Tactics

North Korean Hackers Target Brazilian Fintech with Sophisticated Phishing Tactics

Jun 14, 2024 Cyber Espionage / Cryptocurrency
Threat actors linked to North Korea have accounted for one-third of all the phishing activity targeting Brazil since 2020, as the country's emergence as an influential power has drawn the attention of cyber espionage groups. "North Korean government-backed actors have targeted the Brazilian government and Brazil's aerospace, technology, and financial services sectors," Google's Mandiant and Threat Analysis Group (TAG) divisions said in a joint report published this week. "Similar to their targeting interests in other regions, cryptocurrency and financial technology firms have been a particular focus, and at least three North Korean groups have targeted Brazilian cryptocurrency and fintech companies." Prominent among those groups is a threat actor tracked as UNC4899 (aka Jade Sleet, PUKCHONG, and TraderTraitor), which has targeted cryptocurrency professionals with a malware-laced trojanized Python app. The attack chains involve reaching out to pote...
Meta Halts AI Use in Brazil Following Data Protection Authority's Ban

Meta Halts AI Use in Brazil Following Data Protection Authority's Ban

Jul 18, 2024 Artificial Intelligence / Data Protection
Meta has suspended the use of generative artificial intelligence (GenAI) in Brazil after the country's data protection authority issued a preliminary ban objecting to its new privacy policy. The development was first reported by news agency Reuters. The company said it has decided to suspend the tools while it is in talks with Brazil's National Data Protection Authority (ANPD) to address the agency's concerns over its use of GenAI technology. Earlier this month, ANPD halted with immediate effect the social media giant's new privacy policy that granted the company access to users' personal data to train its GenAI systems. The decision stems from "the imminent risk of serious and irreparable damage or difficult-to-repair damage to the fundamental rights of the affected data subjects," the agency said. It further set a daily fine of 50,000 reais (about $9,100 as of July 18) in case of non-compliance. Last week, it gave Meta "five more days to p...

New "Raptor Train" IoT Botnet Compromises Over 200,000 Devices Worldwide

Sep 18, 2024 IoT Security / Threat Intelligence
Cybersecurity researchers have uncovered a never-before-seen botnet comprising an army of small office/home office (SOHO) and IoT devices that are likely operated by a Chinese nation-state threat actor called Flax Typhoon (aka Ethereal Panda or RedJuliett). The sophisticated botnet, dubbed Raptor Train by Lumen's Black Lotus Labs, is believed to have been operational since at least May 2020, hitting a peak of 60,000 actively compromised devices in June 2023. "Since that time, there have been more than 200,000 SOHO routers, NVR/DVR devices, network attached storage (NAS) servers, and IP cameras; all conscripted into the Raptor Train botnet, making it one of the largest Chinese state-sponsored IoT botnets discovered to-date," the cybersecurity company said in a 81-page report shared with The Hacker News. The infrastructure powering the botnet is estimated to have ensnared hundreds of thousands of devices since its formation, with the network powered by a three-tiered...

WhatsApp Sues Indian Government Over New Internet Regulations

WhatsApp Sues Indian Government Over New Internet Regulations

May 26, 2021
WhatsApp on Wednesday fired a legal salvo against the Indian government to block new regulations that would require messaging apps to trace the "first originator" of messages shared on the platform, thus effectively breaking encryption protections. "Requiring messaging apps to 'trace' chats is the equivalent of asking us to keep a fingerprint of every single message sent on WhatsApp, which would break end-to-end encryption and fundamentally undermines people's right to privacy," a WhatsApp spokesperson told The Hacker News via email. "We have consistently joined civil society and experts around the world in opposing requirements that would violate the privacy of our users." With over 530 million active users, India is WhatsApp's biggest market by users.  The lawsuit, filed by the Facebook-owned messaging service in the Delhi High Court, seeks to bar new internet rules that come into force effective May 26. Called the Intermediary Guide...

Lazarus Group Uses React-Based Admin Panel to Control Global Cyber Attacks

Lazarus Group Uses React-Based Admin Panel to Control Global Cyber Attacks

Jan 29, 2025 Threat Intelligence / Malware
The North Korean threat actor known as the Lazarus Group has been observed leveraging a "web-based administrative platform" to oversee its command-and-control (C2) infrastructure, giving the adversary the ability to centrally supervise all aspects of their campaigns. "Each C2 server hosted a web-based administrative platform, built with a React application and a Node.js API," SecurityScorecard's STRIKE team said in a new report shared with The Hacker News. "This administrative layer was consistent across all the C2 servers analyzed, even as the attackers varied their payloads and obfuscation techniques to evade detection." The hidden framework has been described as a comprehensive system and a hub that allows attackers to organize and manage exfiltrated data, maintain oversight of their compromised hosts, and handle payload delivery. The web-based admin panel has been identified in connection with a supply chain attack campaign dubbed Operation ...
GhostRedirector Hacks 65 Windows Servers Using Rungan Backdoor and Gamshen IIS Module

GhostRedirector Hacks 65 Windows Servers Using Rungan Backdoor and Gamshen IIS Module

Sep 04, 2025 Data Breach / Malware
Cybersecurity researchers have lifted the lid on a previously undocumented threat cluster dubbed GhostRedirector that has managed to compromise at least 65 Windows servers primarily located in Brazil, Thailand, and Vietnam. The attacks, per Slovak cybersecurity company ESET, led to the deployment of a passive C++ backdoor called Rungan and a native Internet Information Services (IIS) module codenamed Gamshen. The threat actor is believed to be active since at least August 2024. "While Rungan has the capability of executing commands on a compromised server, the purpose of Gamshen is to provide SEO fraud as-a-service, i.e., to manipulate search engine results, boosting the page ranking of a configured target website," ESET researcher Fernando Tavella said in a report shared with The Hacker News. "Even though Gamshen only modifies the response when the request comes from Googlebot – i.e., it does not serve malicious content or otherwise affect regular visitors of the ...

Custom Backdoor Exploiting Magic Packet Vulnerability in Juniper Routers

Jan 23, 2025 Malware / Enterprise Security
Enterprise-grade Juniper Networks routers have become the target of a custom backdoor as part of a campaign dubbed J-magic . According to the Black Lotus Labs team at Lumen Technologies, the activity is so named for the fact that the backdoor continuously monitors for a "magic packet" sent by the threat actor in TCP traffic.  "J-magic campaign marks the rare occasion of malware designed specifically for Junos OS, which serves a similar market but relies on a different operating system, a variant of FreeBSD," the company said in a report shared with The Hacker News. Evidence gathered by the company shows that the earliest sample of the backdoor dates back to September 2023, with the activity ongoing between mid-2023 and mid-2024. Semiconductor, energy, manufacturing, and information technology (IT) sectors were the most targeted. Infections have been reported across Europe, Asia, and South America, including Argentina, Armenia, Brazil, Chile, Colombia, Indone...

⚡ Weekly Recap: WSUS Exploited, LockBit 5.0 Returns, Telegram Backdoor, F5 Breach Widens

Oct 27, 2025 Cybersecurity / Hacking News
Security, trust, and stability — once the pillars of our digital world — are now the tools attackers turn against us. From stolen accounts to fake job offers, cybercriminals keep finding new ways to exploit both system flaws and human behavior. Each new breach proves a harsh truth: in cybersecurity, feeling safe can be far more dangerous than being alert. Here’s how that false sense of security was broken again this week. ⚡ Threat of the Week Newly Patched Critical Microsoft WSUS Flaw Comes Under Attack — Microsoft released out-of-band security updates to patch a critical-severity Windows Server Update Service (WSUS) vulnerability that has since come under active exploitation in the wild.

⚡ Weekly Recap: SharePoint 0-Day, Chrome Exploit, macOS Spyware, NVIDIA Toolkit RCE and More

Jul 21, 2025 Enterprise Security / Zero Day
Even in well-secured environments, attackers are getting in—not with flashy exploits, but by quietly taking advantage of weak settings, outdated encryption, and trusted tools left unprotected. These attacks don’t depend on zero-days. They work by staying unnoticed—slipping through the cracks in what we monitor and what we assume is safe. What once looked suspicious now blends in, thanks to modular techniques and automation that copy normal behavior. The real concern? Control isn’t just being challenged—it’s being quietly taken. This week’s updates highlight how default settings, blurred trust boundaries, and exposed infrastructure are turning everyday systems into entry points. ⚡ Threat of the Week Critical SharePoint Zero-Day Actively Exploited (Patch Released Today) — Microsoft has released fixes to address two security flaws in SharePoint Server that have come under active exploitation in the wild to breach dozens of organizations across the world. Details of exploitation emer...

Jun 02, 2025 Cybersecurity / Hacking News
If this had been a security drill, someone would’ve said it went too far. But it wasn’t a drill—it was real. The access? Everything looked normal. The tools? Easy to find. The detection? Came too late. This is how attacks happen now—quiet, convincing, and fast. Defenders aren’t just chasing hackers anymore—they’re struggling to trust what their systems are telling them. The problem isn’t too few alerts. It’s too many, with no clear meaning. One thing is clear: if your defense still waits for obvious signs, you’re not protecting anything. You’re just watching it happen. This recap highlights the moments that mattered—and why they’re worth your attention. ⚡ Threat of the Week APT41 Exploits Google Calendar for Command-and-Control — The Chinese state-sponsored threat actor known as APT41 deployed a malware called TOUGHPROGRESS that uses Google Calendar for command-and-control (C2).
