5 Network Security Threats And How To Protect Yourself

5 Network Security Threats And How To Protect Yourself

September 26, 2022The Hacker News
Cybersecurity today matters so much because of everyone's dependence on technology, from collaboration, communication and collecting data to e-commerce and entertainment. Every organisation that needs to deliver services to their customers and employees must protect their IT 'network' - all the apps and connected devices from laptops and desktops to servers and smartphones. While traditionally, these would all live on one "corporate network," - networks today are often just made up of the devices themselves, and how they're connected: across the internet, sometimes via VPNs, to the homes and cafes people work from, to the cloud and data centres where services live. So what threats does this modern network face? Let's look at them in more detail. #1 Misconfiguration According to recent research by  Verizon , misconfiguration errors and misuse now make up 14% of breaches. Misconfiguration errors occur when configuring a system or application so that it&
CISA Warns of Hackers Exploiting Recent Zoho ManageEngine Vulnerability

CISA Warns of Hackers Exploiting Recent Zoho ManageEngine Vulnerability

September 23, 2022Ravie Lakshmanan
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Thursday  added  a recently disclosed security flaw in Zoho ManageEngine to its Known Exploited Vulnerabilities ( KEV ) Catalog, citing evidence of active exploitation. "Zoho ManageEngine PAM360, Password Manager Pro, and Access Manager Plus contain an unspecified vulnerability which allows for remote code execution," the agency said in a notice. The  critical vulnerability , tracked as  CVE-2022-35405 , is rated 9.8 out of 10 for severity on the CVSS scoring system, and was patched by Zoho as part of updates released on June 24, 2022. Although the exact nature of the flaw remains unknown, the India-based enterprise solutions company  said  it addressed the issue by removing the vulnerable components that could lead to the remote execution of arbitrary code. Zoho has also warned of the public availability of a proof-of-concept (PoC) exploit for the vulnerability, making it imperative that customers move
Researchers Disclose Critical Vulnerability in Oracle Cloud Infrastructure

Researchers Disclose Critical Vulnerability in Oracle Cloud Infrastructure

September 22, 2022Ravie Lakshmanan
Researchers have disclosed a new severe Oracle Cloud Infrastructure (OCI) vulnerability that could be exploited by users to access the virtual disks of other Oracle customers. "Each virtual disk in Oracle's cloud has a unique identifier called OCID," Shir Tamari, head of research at Wiz,  said  in a series of tweets. "This identifier is not considered secret, and organizations do not treat it as such." "Given the OCID of a victim's disk that is not currently attached to an active server or configured as shareable, an attacker could 'attach' to it and obtain read/write over it," Tamari added. The cloud security firm, which dubbed the tenant isolation vulnerability " AttachMe ," said Oracle  patched the issue  within 24 hours of responsible disclosure on June 9, 2022. Accessing a volume using the CLI without sufficient permissions At its core, the vulnerability is rooted in the fact that a disk could be attached to a compute
15-Year-Old Unpatched Python Vulnerability Potentially Affects Over 350,000 Projects

15-Year-Old Unpatched Python Vulnerability Potentially Affects Over 350,000 Projects

September 22, 2022Ravie Lakshmanan
As many as 350,000 open source projects are believed to be potentially vulnerable to exploitation as a result of a security flaw in a Python module that has remained unpatched for 15 years. The open source repositories span a number of industry verticals, such as software development, artificial intelligence/machine learning, web development, media, security, and IT management. The shortcoming, tracked as  CVE-2007-4559  (CVSS score: 6.8), is rooted in the tarfile module, successful exploitation of which could lead to code execution from an arbitrary file write. "The vulnerability is a path traversal attack in the extract and extractall functions in the tarfile module that allow an attacker to overwrite arbitrary files by adding the '..' sequence to filenames in a TAR archive," Trellix security researcher Kasimir Schulz  said  in a writeup. Originally disclosed in August 2007, the bug has to do with how a specially crafted tar archive can be leveraged to overwri

Hackers Targeting Unpatched Atlassian Confluence Servers to Deploy Crypto Miners

A now-patched critical security flaw affecting Atlassian Confluence Server that came to light a few months ago is being actively exploited for illicit cryptocurrency mining on unpatched installations. "If left unremedied and successfully exploited, this vulnerability could be used for multiple and more malicious attacks, such as a complete domain takeover of the infrastructure and the deployment information stealers, remote access trojans (RATs), and ransomware," Trend Micro threat researcher Sunil Bharti  said  in a report. The issue, tracked as  CVE-2022-26134  (CVSS score: 9.8), was addressed by the Australian software company in June 2022. In one of the infection chains observed by the cybersecurity company, the flaw was leveraged to download and run a shell script ("ro.sh") on the victim's machine, which, in turn, fetched a second shell script ("ap.sh"). The malicious code is designed to update the  PATH variable  to include additional paths
