Malicious NPM Package Caught Stealing Users' Saved Passwords From Browsers

Malicious NPM Package Caught Stealing Users' Saved Passwords From Browsers

July 21, 2021Ravie Lakshmanan
A software package available from the official NPM repository has been revealed to be actually a front for a tool that's designed to steal saved passwords from the Chrome web browser. The package in question, named " nodejs_net_server " and downloaded over 1,283 times since February 2019, was last updated seven months ago (version 1.1.2), with its corresponding repository leading to non-existent locations hosted on GitHub.  "It isn't malicious by itself, but it can be when put into the malicious use context," ReversingLabs researcher Karlo Zanki  said  in an analysis shared with The Hacker News. "For instance, this package uses it to perform malicious password stealing and credential exfiltration. Even though this off-the-shelf password recovery tool comes with a graphical user interface, malware authors like to use it as it can also be run from the command line." While the first version of the package was put out just to test the process of p
XLoader Windows InfoStealer Malware Now Upgraded to Attack macOS Systems

XLoader Windows InfoStealer Malware Now Upgraded to Attack macOS Systems

July 21, 2021Ravie Lakshmanan
A popular malware known for stealing sensitive information from Windows machines has evolved into a new strain capable of also targeting Apple's macOS operating system. The upgraded malware, dubbed "XLoader," is a successor to another well-known Windows-based info stealer called Formbook that's known to vacuum credentials from various web browsers, capture screenshots, record keystrokes, and download and execute files from attacker-controlled domains. "For as low as $49 on the Darknet, hackers can buy licenses for the new malware, enabling capabilities to harvest log-in credentials, collect screenshots, log keystrokes, and execute malicious files," cybersecurity firm Check Point said in a report shared with The Hacker News. Distributed via spoofed emails containing malicious Microsoft Office documents, XLoader is estimated to infected victims spanning across 69 countries between December 1, 2020, and June 1, 2021, with 53% of the infections reported in
Several New Critical Flaws Affect CODESYS Industrial Automation Software

Several New Critical Flaws Affect CODESYS Industrial Automation Software

July 21, 2021Ravie Lakshmanan
Cybersecurity researchers on Wednesday disclosed multiple security vulnerabilities impacting CODESYS automation software and the WAGO programmable logic controller (PLC) platform that could be remotely exploited to take control of a company's cloud operational technology (OT) infrastructure. The flaws can be turned "into innovative attacks that could put threat actors in position to remotely control a company's cloud OT implementation, and threaten any industrial process managed from the cloud," the New York-headquartered industrial security company Claroty said in a report shared with The Hacker News, adding they "can be used to target a cloud-based management console from a compromised field device, or take over a company's cloud and attack PLCs and other devices to disrupt operations." CODESYS is a development environment for programming controller applications, enabling easy configuration of PLCs in industrial control systems. WAGO PFC100/200 is
[eBook] A Guide to Stress-Free Cybersecurity for Lean IT Security Teams

[eBook] A Guide to Stress-Free Cybersecurity for Lean IT Security Teams

July 21, 2021The Hacker News
Today's cybersecurity landscape is enough to make any security team concerned. The rapid evolution and increased danger of attack tactics have put even the largest corporations and governments at heightened risk. If the most elite security teams can't prevent these attacks from happening, what can lean security teams look forward to?  Surprisingly, leaner teams have a much greater chance than they think. It might seem counterintuitive, but recent history has shown that large numbers and huge budgets aren't the difference-makers they once were. Indeed, having the right strategy in place is a clear indicator of an organization's success today. A new guide by XDR provider Cynet ( download it here ) looks to dispel the myth that bigger is always better and shows a smarter way forward for lean IT security teams. The new guide focuses on helping lean IT security teams plan strategies that can protect their organizations while reducing the level of stress they face. Due to the rise of cyb
New Windows and Linux Flaws Give Attackers Highest System Privileges

New Windows and Linux Flaws Give Attackers Highest System Privileges

Microsoft's Windows 10 and the upcoming Windows 11 versions have been found vulnerable to a new local privilege escalation vulnerability that permits users with low-level permissions access Windows system files, in turn, enabling them to unmask the operating system installation password and even decrypt private keys. The vulnerability has been nicknamed "SeriousSAM." "Starting with Windows 10 build 1809, non-administrative users are granted access to SAM, SYSTEM, and SECURITY registry hive files," CERT Coordination Center (CERT/CC) said in a  vulnerability note  published Monday. "This can allow for local privilege escalation (LPE)." The operating system configuration files in question are as follows - c:\Windows\System32\config\sam c:\Windows\System32\config\system c:\Windows\System32\config\security Microsoft, which is tracking the vulnerability under the identifier  CVE-2021-36934 , acknowledged the issue, but has yet to roll out a patch, o
16-Year-Old Security Bug Affects Millions of HP, Samsung, Xerox Printers

16-Year-Old Security Bug Affects Millions of HP, Samsung, Xerox Printers

July 20, 2021Ravie Lakshmanan
Details have emerged about a high severity security vulnerability affecting a software driver used in HP, Xerox, and Samsung printers that has remained undetected since 2005. Tracked as  CVE-2021-3438  (CVSS score: 8.8), the issue concerns a buffer overflow in a print driver installer package named "SSPORT.SYS" that can enable remote privilege and arbitrary code execution. Hundreds of millions of printers have been released worldwide to date with the vulnerable driver in question. However, there is no evidence that the flaw was abused in real-world attacks. "A potential buffer overflow in the software drivers for certain HP LaserJet products and Samsung product printers could lead to an escalation of privilege," according to an advisory published in May. The issue was reported to HP by threat intelligence researchers from SentinelLabs on February 18, 2021, following which  remedies  have been  published  for the affected printers as of May 19, 2021.

This New Malware Hides Itself Among Windows Defender Exclusions to Evade Detection

This New Malware Hides Itself Among Windows Defender Exclusions to Evade Detection

Cybersecurity researchers on Tuesday lifted the lid on a previously undocumented malware strain dubbed " MosaicLoader " that singles out individuals searching for cracked software as part of a global campaign. "The attackers behind MosaicLoader created a piece of malware that can deliver any payload on the system, making it potentially profitable as a delivery service," Bitdefender researchers said in a  report  shared with The Hacker News. "The malware arrives on target systems by posing as cracked installers. It downloads a malware sprayer that obtains a list of URLs from the C2 server and downloads the payloads from the received links." The malware has been so named because of its sophisticated internal structure that's orchestrated to prevent reverse-engineering and evade analysis. Attacks involving MosaicLoader rely on a well-established tactic for malware delivery called search engine optimization (SEO) poisoning, wherein cybercriminals purc
