Nowadays, more malware developers are using unconventional programming languages to bypass advanced detection systems. The Node.js malware Lu0Bot is a testament to this trend. By targeting a platform-agnostic runtime environment common in modern web apps and employing multi-layer obfuscation, Lu0Bot is a serious threat to organizations and individuals. Although currently, the malware has low activity, the attackers are likely waiting for the right moment to strike.  To be prepared for any future scenario, a team of analysts conducted an in-depth technical analysis of one of the recent samples of Lu0Bot and  published an article  documenting their process. Here's an overview of their research. Static analysis of the Lu0Bot sample  The  sample  under investigation used an SFX packer, a self-extracting archive that can be opened with any archive utility. Its contents were explored individually. Archive contents 1. BAT-file The content of the BAT fil...

Cybersecurity researchers are calling attention to a new campaign that's leveraging a combination of ClickFix lures and fake adult websites to deceive users into running malicious commands under the guise of a "critical" Windows security update. "Campaign leverages fake adult websites (xHamster, PornHub clones) as its phishing mechanism, likely distributed via malvertising," Acronis said in a new report shared with The Hacker News. "The adult theme, and possible connection to shady websites, adds to the victim's psychological pressure to comply with sudden 'security update' installation." ClickFix-style attacks have surged over the past year, typically tricking users into running malicious commands on their own machines using prompts for technical fixes or completing CAPTCHA verification checks. According to data from Microsoft, ClickFix has become the most common initial access method, accounting for 47% of attacks. The latest camp...

Guess what? If you own a Windows PC, which is fully-patched, attackers can still hack your computer. Isn't that scary? Well, definitely for most of you. Security researchers have discovered a new technique that could allow attackers to inject malicious code on every version of Microsoft's Windows operating system, even Windows 10, in a manner that no existing anti-malware tools can detect, threaten millions of PCs worldwide. Dubbed " AtomBombing ," the technique does not exploit any vulnerability but abuses a designing weakness in Windows. New Code Injection Attack helps Malware Bypass Security Measures AtomBombing attack abuses the system-level Atom Tables, a feature of Windows that allows applications to store information on strings, objects, and other types of data to access on a regular basis. And since Atom are shared tables, all sorts of applications can access or modify data inside those tables. You can read a more detailed explanation of Atom T...

So, How do Hackers compromise a Website? Simply by exploiting the flaws in it, that means they took advantage of the error in the developers' code. Now, this time the hackers itself has left behind a crucial flaw in its malware code which can be exploited by us to help save our computer systems. Believe me, it's not an April Fools' joke! A malicious software program that holds the victims' computer files hostage by wrapping them with strong encryption until the victim pays a ransom fee to get them decrypted, has a critical flaw in its malware code itself that it leaves the decryption key on the victim's computer. The Anti-virus firm Symantec examined a sophisticated malware program dubbed as CryptoDefense (Trojan.Cryptodefense) ransomware , which appeared in the end of the last month. CryptoDefense is one of the complex malware programs that include a number of effective techniques, including Tor anonymity tool usage and Bitcoin digital currency to extort money from victims. Cryp...

Threat actors with ties to North Korea have likely become the latest to exploit the recently disclosed critical React2Shell security flaw in React Server Components (RSC) to deliver a previously undocumented remote access trojan dubbed EtherRAT . "EtherRAT leverages Ethereum smart contracts for command-and-control (C2) resolution, deploys five independent Linux persistence mechanisms, and downloads its own Node.js runtime from nodejs.org," Sysdig said in a report published Monday. The cloud security firm said the activity exhibits significant overlap with a long-running campaign codenamed Contagious Interview , which has been observed leveraging the EtherHiding technique to distribute malware since February 2025. Contagious Interview is the name given to a series of attacks in which blockchain and Web3 developers, among others, are targeted through fake job interviews, coding assignments, and video assessments, leading to the deployment of malware. These efforts typi...

A new piece of research from academics at ETH Zurich has identified a number of critical security issues in the MEGA cloud storage service that could be leveraged to break the confidentiality and integrity of user data. In a paper titled " MEGA: Malleable Encryption Goes Awry ," the researchers point out how MEGA's system does not protect its users against a malicious server, thereby enabling a rogue actor to fully compromise the privacy of the uploaded files. "Additionally, the integrity of user data is damaged to the extent that an attacker can insert malicious files of their choice which pass all authenticity checks of the client," ETH Zurich's Matilda Backendal, Miro Haller, and Kenneth G. Paterson said in an analysis of the service's cryptographic architecture. MEGA, which  advertises  itself as the "privacy company" and claims to provide user-controlled end-to-end encrypted cloud storage, has more than 10 million daily active users, w...

The North Korean threat actor known as Kimsuky has been linked to a new campaign that distributes a new variant of Android malware called DocSwap via QR codes hosted on phishing sites mimicking Seoul-based logistics firm CJ Logistics (formerly CJ Korea Express). "The threat actor leveraged QR codes and notification pop-ups to lure victims into installing and executing the malware on their mobile devices," ENKI said . "The malicious app decrypts an embedded encrypted APK and launches a malicious service that provides RAT capabilities." "Since Android blocks apps from unknown sources and displays security warnings by default, the threat actor claims the app is a safe, official release to trick victims into ignoring the warning and installing the malware." According to the South Korean cybersecurity company, some of these artifacts masquerade as package delivery service apps. It's being assessed that the threat actors are using smishing texts or phi...

Cybersecurity researchers have discovered a serious security issue that allows leaked Laravel APP_KEYs to be weaponized to gain remote code execution capabilities on hundreds of applications. "Laravel's APP_KEY, essential for encrypting sensitive data, is often leaked publicly (e.g., on GitHub)," GitGuardian said . "If attackers get access to this key, they can exploit a deserialization flaw to execute arbitrary code on the server – putting data and infrastructure at risk." The company, in collaboration with Synacktiv, said it was able to extract more than 260,000 APP_KEYs from GitHub from 2018 to May 30, 2025, identifying over 600 vulnerable Laravel applications in the process. GitGuardian said it observed over 10,000 unique APP_KEYs across GitHub, of which 400 APP_KEYs were validated as functional. APP_KEY is a random 32-byte encryption key that's generated during the installation of Laravel. Stored in the .env file of the application, it's used ...

After Adobe today releases its first Patch Tuesday updates for 2020, Microsoft has now also published its January security advisories warning billions of users of 49 new vulnerabilities in its various products. What's so special about the latest Patch Tuesday is that one of the updates fixes a serious flaw in the core cryptographic component of widely used Windows 10, Server 2016 and 2019 editions that was discovered and reported to the company by the National Security Agency (NSA) of the United States. What's more interesting is that this is the first security flaw in Windows OS that the NSA reported responsibly to Microsoft, unlike the  Eternalblue SMB flaw that the agency kept secret for at least five years and then was leaked to the public by a mysterious group, which caused WannaCry menace in 2017. CVE-2020-0601: Windows CryptoAPI Spoofing Vulnerability According to an advisory released by Microsoft, the flaw, dubbed ' NSACrypt ' and tracked as CVE-20...

Several malicious packages have been uncovered across the npm, Python, and Ruby package repositories that drain funds from cryptocurrency wallets, erase entire codebases after installation, and exfiltrate Telegram API tokens, once again demonstrating the variety of supply chain threats lurking in open-source ecosystems. The findings come from multiple reports published by Checkmarx, ReversingLabs, Safety, and Socket in recent weeks. The list of identified packages across these platforms are listed below - Socket noted that the two malicious gems were published by a threat actor under the aliases Bùi nam, buidanhnam, and si_mobile merely days after Vietnam ordered a nationwide ban on the Telegram messaging app late last month for allegedly not cooperating with the government to tackle illicit activities related to fraud, drug trafficking, and terrorism. "These gems silently exfiltrate all data sent to the Telegram API by redirecting traffic through a command-and-control (C2...

After the wide chain of scandals over US global snooping that seriously damaged the trust on the top U.S. Tech companies, Google and Yahoo! came forward and took initiative to provide more secure, encrypted and NSA-proofed service in an effort to gain their reputation again among its users. Now, Microsoft has also announced several improvements to the encryption used in its online cloud services in order to protect them from cyber criminals, bad actors and prying eyes. The company effort detailed in a blog entry by Matt Thomlinson, Microsoft's Vice President of Trustworthy Computing Security. MICROSOFT'S COMMITMENT Last December, Microsoft promised to protect its users data from government snooping by expanding encryption across its services, reinforcing legal protections for its customers' data and enhancing the transparency of its software code, making it easier for the customers to reassure themselves that its products contain no backdoors. Yesterday's announc...

Air-gapped computers that are isolated from the Internet and physically separated from local networks are believed to be the most secure computers which are difficult to infiltrate. However, these networks have been a regular target in recent years for researchers, who have been trying to demonstrate every possible attack scenarios that could compromise the security of such isolated networks. Security researchers from Ben-Gurion University in Israel have previously demonstrated several ways to extract sensitive information from air-gapped computers. Now, the same University researchers have discovered another way to steal confidential information from air-gapped computers – this time with the help of infrared-equipped CCTV cameras that are used for night vision. Researchers have developed a new attack scenario, dubbed aIR-Jumper, which includes an infected air-gapped computer (from which data needs to be stolen) and an infected CCTV network (that has at least one CCTV insta...
