A threat actor known as ShadyPanda has been linked to a seven-year-long browser extension campaign that has amassed over 4.3 million installations over time. Five of these extensions started off as legitimate programs before malicious changes were introduced in mid-2024, according to a report from Koi Security, attracting 300,000 installs. These extensions have since been taken down. "These extensions now run hourly remote code execution – downloading and executing arbitrary JavaScript with full browser access," security researcher Tuval Admoni said in a report shared with The Hacker News. "They monitor every website visit, exfiltrate encrypted browsing history, and collect complete browser fingerprints." To make matters worse, one of the extensions, Clean Master, was featured and verified by Google at one point. This trust-building exercise allowed the attackers to expand their user base and silently issue malicious updates years later without attracting any...

Cybersecurity researchers have disclosed three now-patched security vulnerabilities impacting Google's Gemini artificial intelligence (AI) assistant that, if successfully exploited, could have exposed users to major privacy risks and data theft. "They made Gemini vulnerable to search-injection attacks on its Search Personalization Model; log-to-prompt injection attacks against Gemini Cloud Assist; and exfiltration of the user's saved information and location data via the Gemini Browsing Tool," Tenable security researcher Liv Matan said in a report shared with The Hacker News. The vulnerabilities have been collectively codenamed the Gemini Trifecta by the cybersecurity company. They reside in three distinct components of the Gemini suite - A prompt injection flaw in Gemini Cloud Assist that could allow attackers to exploit cloud-based services and compromise cloud resources by taking advantage of the fact that the tool is capable of summarizing logs pulled dir...

If you are a fan of Unreal Tournament from Epic Games or ever have participated in discussions on the online forums run by Epic Games, you possibly need to change your forum password as soon as possible. It seems the Unreal Engine and its creators, Epic Games' forums have recently been compromised by an unknown hacker or a group of hackers, who have stolen more than 800,000 forum accounts with over half a Million from the Unreal Engine's forums alone. The hackers get their hands on the forum accounts by exploiting a known vulnerability resided in an outdated version of the vBulletin forum software, which allowed them to get access to the full database. Epic believes registration information that includes usernames, scrambled passwords, email addresses, dates of birth, IP addresses, and date of joining, may have been obtained in the attack. "We believe a recent Unreal Engine and Unreal Tournament forum compromise revealed email addresses and other data entered in...

A new malware campaign has been observed leveraging social engineering tactics to deliver an open-source rootkit called r77 . The activity, condemned OBSCURE#BAT by Securonix, enables threat actors to establish persistence and evade detection on compromised systems. It's currently not known who is behind the campaign. The rootkit "has the ability to cloak or mask any file, registry key or task beginning with a specific prefix," security researchers Den Iuzvyk and Tim Peck said in a report shared with The Hacker News. "It has been targeting users by either masquerading as legitimate software downloads or via fake captcha social engineering scams." The campaign is designed to mainly target English-speaking individuals, particularly the United States, Canada, Germany, and the United Kingdom. OBSCURE#BAT gets its name from the fact that the starting point of the attack is an obfuscated Windows batch script that, in turn, executes PowerShell commands to activ...

Some risks don’t breach the perimeter—they arrive through signed software, clean resumes, or sanctioned vendors still hiding in plain sight. This week, the clearest threats weren’t the loudest—they were the most legitimate-looking. In an environment where identity, trust, and tooling are all interlinked, the strongest attack path is often the one that looks like it belongs. Security teams are now challenged to defend systems not just from intrusions—but from trust itself being turned into a weapon. ⚡ Threat of the Week Microsoft SharePoint Attacks Traced to China — The fallout from an attack spree targeting defects in on-premises Microsoft SharePoint servers continues to spread a week after the discovery of the zero-day exploits, with more than 400 organizations globally compromised. The attacks have been attributed to two known Chinese hacking groups tracked as Linen Typhoon (aka APT27), Violet Typhoon (aka APT31), and a suspected China-based threat actor codenamed Storm-2603 t...

Cybersecurity today moves at the pace of global politics. A single breach can ripple across supply chains, turn a software flaw into leverage, or shift who holds the upper hand. For leaders, this means defense isn’t just a matter of firewalls and patches—it’s about strategy. The strongest organizations aren’t the ones with the most tools, but the ones that see how cyber risks connect to business, trust, and power. This week’s stories highlight how technical gaps become real-world pressure points—and why security decisions now matter far beyond IT. ⚡ Threat of the Week Popular Password Managers Affected by Clickjacking — Popular password manager plugins for web browsers have been found susceptible to clickjacking security vulnerabilities that could be exploited to steal account credentials, two-factor authentication (2FA) codes, and credit card details under certain conditions. The technique has been dubbed Document Object Model (DOM)-based extension clickjacking by independent sec...

Imagine you could gain access to any Fortune 100 company for $10 or less, or even for free. Terrifying thought, isn’t it? Or exciting, depending on which side of the cybersecurity barricade you are on. Well, that’s basically the state of things today. Welcome to the infostealer garden of low-hanging fruit. Over the last few years, the problem has grown bigger and bigger, and only now are we slowly learning its full destructive potential. In this article, we will describe how the entire cybercriminal ecosystem operates, the ways various threat actors exploit data originating from it, and most importantly, what you can do about it. Let’s start with what infostealer malware actually is. As the name suggests, it’s malware that... steals data. Depending on the specific type, the information it extracts might differ slightly, but most will try to extract the following: Cryptocurrency wallets Bank account information and saved credit card details Saved passwords from various apps Bro...
