Experts Detail New Flaws in Azure HDInsight Spark, Kafka, and Hadoop Services

Feb 06, 2024 Vulnerability / Cloud Security
Three new security vulnerabilities have been discovered in Azure HDInsight's Apache  Hadoop ,  Kafka , and  Spark  services that could be exploited to achieve privilege escalation and a regular expression denial-of-service ( ReDoS ) condition. "The new vulnerabilities affect any authenticated user of Azure HDInsight services such as Apache Ambari and Apache Oozie," Orca security researcher Lidor Ben Shitrit  said  in a technical report shared with The Hacker News. The list of flaws is as follows - CVE-2023-36419  (CVSS score: 8.8) - Azure HDInsight Apache Oozie Workflow Scheduler XML External Entity (XXE) Injection Elevation of Privilege Vulnerability CVE-2023-38156  (CVSS score: 7.2) - Azure HDInsight Apache Ambari Java Database Connectivity (JDBC) Injection Elevation of Privilege Vulnerability Azure HDInsight Apache Oozie Regular Expression Denial-of-Service (ReDoS) Vulnerability (no CVE) The two privilege escalation flaws could be exploited by an authenticate
29-Year-Old Ukrainian Cryptojacking Kingpin Arrested for Exploiting Cloud Services

29-Year-Old Ukrainian Cryptojacking Kingpin Arrested for Exploiting Cloud Services

Jan 13, 2024 Cryptojacking / Cloud Security
A 29-year-old Ukrainian national has been arrested in connection with running a "sophisticated cryptojacking scheme," netting them over $2 million (€1.8 million) in illicit profits. The person, described as the "mastermind" behind the operation, was apprehended in Mykolaiv, Ukraine, on January 9 by the National Police of Ukraine with support from Europol and an unnamed cloud service provider following "months of intensive collaboration." "A cloud provider approached Europol back in January 2023 with information regarding compromised cloud user accounts of theirs," Europol  said , adding it shared the intelligence with the Ukrainian authorities. The Cyber Police of Ukraine, in a separate announcement, said the suspect "infected the servers of a well-known American company with a miner virus" at least since 2021, using custom brute-force tools to infiltrate 1,500 accounts of the firm. "Using the compromised accounts, the hacker gained access to the management of the service," the a
How to Get Going with CTEM When You Don't Know Where to Start

How to Get Going with CTEM When You Don't Know Where to Start

Oct 04, 2024Vulnerability Management / Security Posture
Continuous Threat Exposure Management (CTEM) is a strategic framework that helps organizations continuously assess and manage cyber risk. It breaks down the complex task of managing security threats into five distinct stages: Scoping, Discovery, Prioritization, Validation, and Mobilization. Each of these stages plays a crucial role in identifying, addressing, and mitigating vulnerabilities - before they can be exploited by attackers.  On paper, CTEM sounds great . But where the rubber meets the road – especially for CTEM neophytes - implementing CTEM can seem overwhelming. The process of putting CTEM principles into practice can look prohibitively complex at first. However, with the right tools and a clear understanding of each stage, CTEM can be an effective method for strengthening your organization's security posture.  That's why I've put together a step-by-step guide on which tools to use for which stage. Want to learn more? Read on… Stage 1: Scoping  When you're defin
Google Warns How Hackers Could Abuse Calendar Service as a Covert C2 Channel

Google Warns How Hackers Could Abuse Calendar Service as a Covert C2 Channel

Nov 06, 2023 Cyber Attack / Online Security
Google is warning of multiple threat actors sharing a public proof-of-concept (PoC) exploit that leverages its Calendar service to host command-and-control (C2) infrastructure. The tool, called Google Calendar RAT (GCR) , employs Google Calendar Events for C2 using a Gmail account. It was first published to GitHub in June 2023. "The script creates a 'Covert Channel' by exploiting the event descriptions in Google Calendar," according to its developer and researcher Valerio Alessandroni, who goes by the online alias MrSaighnal. "The target will connect directly to Google." The tech giant, in its eighth Threat Horizons Report [PDF], said it has not observed the use of the tool in the wild, but noted its Mandiant threat intelligence unit has detected several threat actors sharing the PoC on underground forums. "GCR, running on a compromised machine, periodically polls the Calendar event description for new commands, executes those commands on the t

Eltima SDK Contain Multiple Vulnerabilities Affecting Several Cloud Service Provides

Eltima SDK Contain Multiple Vulnerabilities Affecting Several Cloud Service Provides

Dec 07, 2021
Cybersecurity researchers have disclosed multiple vulnerabilities in a third-party driver software developed by Eltima that have been "unwittingly inherited" by cloud desktop solutions like Amazon Workspaces, Accops, and NoMachine and could provide attackers a path to perform an array of malicious activities. "These vulnerabilities allow attackers to escalate privileges enabling them to disable security products, overwrite system components, corrupt the operating system, or perform malicious operations unimpeded," SentinelOne Senior Security Researcher, Kasif Dekel, said in a report shared with The Hacker News. The 27 flaws have since been addressed in Amazon Nimble Studio AMI, Amazon NICE DCV, Amazon WorkSpaces, Amazon AppStream, NoMachine, Accops HyWorks, Accops HyWorks DVM Tools, Eltima USB Network Gate, Amzetta zPortal Windows zClient, Amzetta zPortal DVM Tools, FlexiHub, and Donglify. At its core, the issues reside in a product developed by Eltima that of
