NGate Campaign Targets Brazil, Trojanizes HandyPay to Steal NFC Data and PINs

NGate Campaign Targets Brazil, Trojanizes HandyPay to Steal NFC Data and PINs

Apr 21, 2026 Mobile Security / Artificial Intelligence
Cybersecurity researchers have discovered a new iteration of an Android malware family called NGate that has been found to abuse a legitimate application called  HandyPay instead of NFCGate. "The threat actors took the app, which is used to relay NFC data, and patched it with malicious code that appears to have been AI-generated," ESET security researcher Lukáš Štefanko said in a report shared with The Hacker News. "As with previous iterations of NGate, the malicious code allows the attackers to transfer NFC data from the victim's payment card to their own device and use it for contactless ATM cash-outs and unauthorized payments." In addition, the malicious payload is capable of capturing the victim's payment card PIN and exfiltrating it to the threat actor's command-and-control (C2) server. NGate, also known as NFSkate, was first publicly documented by the Slovakian cybersecurity vendor in August 2024, detailing its ability to carry out relay a...
Google Patches Antigravity IDE Flaw Enabling Prompt Injection Code Execution

Google Patches Antigravity IDE Flaw Enabling Prompt Injection Code Execution

Apr 21, 2026 Vulnerability / Artificial Intelligence
Cybersecurity researchers have discovered a vulnerability in Google's agentic integrated development environment (IDE), Antigravity, that could be exploited to achieve code execution. The flaw, since patched, combines Antigravity's permitted file-creation capabilities with an insufficient input sanitization in Antigravity's native file-searching tool, find_by_name, to bypass the program's Strict Mode , a restrictive security configuration that limits network access, prevents out-of-workspace writes, and ensures all commands are being run within a sandbox context . "By injecting the -X (exec-batch) flag through the Pattern parameter [in the find_by_name tool], an attacker can force fd to execute arbitrary binaries against workspace files," Pillar Security researcher Dan Lisichkin said in an analysis. "Combined with Antigravity's ability to create files as a permitted action, this enables a full attack chain: stage a malicious script, then trigger ...

⚡ Weekly Recap: Vercel Hack, Push Fraud, QEMU Abused, New Android RATs Emerge & More

Apr 20, 2026 Cybersecurity / Hacking
Monday’s recap shows the same pattern in different places. A third-party tool becomes a way in, then leads to internal access. A trusted download path is briefly swapped to deliver malware. Browser extensions act normally while pulling data and running code. Even update channels are used to push payloads. It’s not breaking systems—it’s bending trust. There’s also a shift in how attacks run. Slower check-ins, multi-stage payloads, andmore code kept in memory. Attackers lean on real tools and normal workflows instead of custom builds. Some cases hint at supply-chain spread, where one weak link reaches further than expected. Go through the whole recap. The pattern across access, execution, and control only shows up when you see it all together. ⚡ Threat of the Week Vercel Discloses Data Breach —Web infrastructure provider Vercel has disclosed a security breach that allows bad actors to gain unauthorized access to "certain" internal Vercel systems.

Why Most AI Deployments Stall After the Demo

Why Most AI Deployments Stall After the Demo

Apr 20, 2026 Artificial Intelligence / Privacy
The fastest way to fall in love with an AI tool is to watch the demo. Everything moves quickly. Prompts land cleanly. The system produces impressive outputs in seconds. It feels like the beginning of a new era for your team. But most AI initiatives don't fail because of bad technology. They stall because what worked in the demo doesn't survive contact with real operations. The gap between a controlled demonstration and day-to-day reality is where teams run into trouble. Most AI product demos are built to highlight potential, not friction. They use clean data, predictable inputs, carefully crafted prompts, and well-understood use cases. Production environments don't look like that. In real operations, data is messy, inputs are inconsistent, systems are fragmented, and context is incomplete. Latency matters. Edge cases quickly outnumber ideal ones. This is why teams often see an initial burst of enthusiasm followed by a slowdown once they try to deploy AI more broadly. W...

Vercel Breach Tied to Context AI Hack Exposes Limited Customer Credentials

Vercel Breach Tied to Context AI Hack Exposes Limited Customer Credentials

Apr 20, 2026 Cloud Security / Data Breach
Web infrastructure provider Vercel has disclosed a security breach that allows bad actors to gain unauthorized access to "certain" internal Vercel systems. The incident stemmed from the compromise of Context.ai, a third-party artificial intelligence (AI) tool, that was used by an employee at the company. "The attacker used that access to take over the employee's Vercel Google Workspace account, which enabled them to gain access to some Vercel environments and environment variables that were not marked as 'sensitive,'" the company said in a bulletin. Vercel said environment variables marked as "sensitive" are stored in an encrypted manner that prevents them from being read, and that there is currently no evidence suggesting that those values were accessed by the attacker. It described the threat actor behind the incident as "sophisticated" based on their "operational velocity and detailed understanding of Vercel's syste...

[Webinar] Eliminate Ghost Identities Before They Expose Your Enterprise Data

Apr 18, 2026 Artificial Intelligence / Enterprise Security
In 2024, compromised service accounts and forgotten API keys were behind 68% of cloud breaches. Not phishing. Not weak passwords. Unmanaged non-human identities that nobody was watching. For every employee in your org, there are 40 to 50 automated credentials: service accounts, API tokens, AI agent connections, and OAuth grants. When projects end or employees leave, most of these stay active. Fully privileged. Completely unmonitored. Attackers don't need to break in. They just pick up the keys you left out. Join our upcoming webinar where we’ll show you how to find and eliminate these "Ghost Identities" before they become a back door for hackers. AI agents and automated workflows are multiplying these credentials at a pace security teams can't manually track. Many carry admin-level access they never needed. One compromised token can give an attacker lateral movement across your entire environment, and the average dwell time fo...
