Researchers Discover Hundreds of Amazon RDS Instances Leaking Users' Personal Data

Researchers Discover Hundreds of Amazon RDS Instances Leaking Users' Personal Data

Nov 16, 2022
Hundreds of databases on Amazon Relational Database Service (Amazon RDS) are exposing personal identifiable information (PII), new findings from Mitiga, a cloud incident response company, show. "Leaking PII in this manner provides a potential treasure trove for threat actors – either during the reconnaissance phase of the cyber kill chain or extortionware/ransomware campaigns," researchers Ariel Szarf, Doron Karmi, and Lionel Saposnik said in a report shared with The Hacker News. This includes names, email addresses, phone numbers, dates of birth, marital status, car rental information, and even company logins. Amazon RDS is a  web service  that makes it possible to set up relational databases in the Amazon Web Services (AWS) cloud. It offers support for different database engines such as MariaDB, MySQL, Oracle, PostgreSQL, and SQL Server. The root cause of the leaks stems from a feature called public  RDS snapshots , which allows for creating a backup of the entire da

Thousands of Borrowers' Data Exposed from ENCollect Debt Collection Service

May 05, 2022
An ElasticSearch server instance that was left open on the Internet without a password contained sensitive financial information about loans from Indian and African financial services. The leak, which was discovered by researchers from information security company UpGuard, amounted to 5.8GB and consisted of a total of 1,686,363 records. "Those records included personal information like name, loan amount, date of birth, account number, and more," UpGuard  said  in a report shared with The Hacker News. "A total of 48,043 unique email addresses were in the collection, some of which were for the product administrators, corporate clients, and collection agents assigned to each case." The exposed instance, used as data storage for a  debt collection platform  called ENCollect, was detected on February 16, 2022. The leaky server has since been rendered non-accessible to the public as of February 28 following intervention from the Indian Computer Emergency Response Tea
How to Find and Fix Risky Sharing in Google Drive

How to Find and Fix Risky Sharing in Google Drive

Mar 06, 2024Data Security / Cloud Security
Every Google Workspace administrator knows how quickly Google Drive becomes a messy sprawl of loosely shared confidential information. This isn't anyone's fault; it's inevitable as your productivity suite is purposefully designed to enable real-time collaboration – both internally and externally.  For Security & Risk Management teams, the untenable risk of any Google Drive footprint lies in the toxic combinations of sensitive data, excessive permissions, and improper sharing. However, it can be challenging to differentiate between typical business practices and potential risks without fully understanding the context and intent.  Material Security, a company renowned for its innovative method of protecting sensitive data within employee mailboxes, has recently launched  Data Protection for Google Drive  to safeguard the sprawl of confidential information scattered throughout Google Drive with a powerful discovery and remediation toolkit. How Material Security helps organ
Microsoft Azure Vulnerability Exposes PostgreSQL Databases to Other Customers

Microsoft Azure Vulnerability Exposes PostgreSQL Databases to Other Customers

Apr 29, 2022
Microsoft on Thursday disclosed that it addressed a pair of issues with the Azure Database for PostgreSQL Flexible Server that could result in unauthorized cross-account database access in a region. "By exploiting an elevated permissions bug in the Flexible Server authentication process for a replication user, a malicious user could leverage an improperly anchored regular expression to bypass authentication to gain access to other customers' databases," Microsoft Security Response Center (MSRC)  said . New York City-based cloud security company Wiz, which uncovered the flaws, dubbed the exploit chain " ExtraReplica ." Microsoft said it mitigated the bug within 48 hours of disclosure on January 13, 2022. Specifically, it relates to a case of privilege escalation in the Azure PostgreSQL engine to gain code execution and a cross-account authentication bypass by means of a forged certificate, allowing an attacker to create a database in the target's Azure r

Muhstik Botnet Targeting Redis Servers Using Recently Disclosed Vulnerability

Muhstik Botnet Targeting Redis Servers Using Recently Disclosed Vulnerability

Mar 28, 2022
Muhstik, a botnet infamous for propagating via web application exploits, has been observed targeting Redis servers using a recently disclosed vulnerability in the database system. The vulnerability relates to  CVE-2022-0543 , a  Lua sandbox escape flaw  in the open-source, in-memory, key-value data store that could be abused to achieve remote code execution on the underlying machine. The vulnerability is rated 10 out of 10 for severity. "Due to a packaging issue, a remote attacker with the ability to execute arbitrary Lua scripts could possibly escape the Lua sandbox and execute arbitrary code on the host," Ubuntu noted in an advisory released last month. According to  telemetry data  gathered by Juniper Threat Labs, the attacks leveraging the new flaw are said to have commenced on March 11, 2022, leading to the retrieval of a malicious shell script ("russia.sh") from a remote server, which is then utilized to fetch and execute the botnet binaries from another s
Multiple Flaws Uncovered in ClickHouse OLAP Database System for Big Data

Multiple Flaws Uncovered in ClickHouse OLAP Database System for Big Data

Mar 16, 2022
Researchers have disclosed seven new security vulnerabilities in an open-source database management system solution called ClickHouse that could be weaponized to crash the servers, leak memory contents, and even lead to the execution of arbitrary code. "The vulnerabilities require authentication, but can be triggered by any user with read permissions," Uriya Yavnieli and Or Peles, researchers from DevSecOps firm JFrog,  said  in a report published Tuesday. "This means the attacker must perform reconnaissance on the specific ClickHouse server target to obtain valid credentials. Any set of credentials would do, since even a user with the lowest privileges can trigger all of the vulnerabilities." The list of seven flaws is below – CVE-2021-43304 and CVE-2021-43305  (CVSS scores: 8.8) – Heap buffer overflow flaws in the LZ4 compression codec that could lead to remote code execution CVE-2021-42387 and CVE-2021-42388  (CVSS scores: 7.1) – Heap out-of-bounds read
Why Database Patching Best Practice Just Doesn't Work and How to Fix It

Why Database Patching Best Practice Just Doesn't Work and How to Fix It

Oct 18, 2021
Patching really, really matters – patching is what keeps technology solutions from becoming like big blocks of Swiss cheese, with endless security vulnerabilities punching hole after hole into critical solutions. But anyone who's spent any amount of time maintaining systems will know that patching is often easier said than done. Yes, in some instances, you can just run a command line to install that patch, and that's it. These instances are increasingly rare though – given the complexity of the technology environment, you're more likely faced with a complex process to achieve patching best practice. In this article, we'll outline why database patching matters (yes, databases are vulnerable too!), explain what the problem is with patching databases, and point to a novel solution that takes the pain out of database patching. Watch out – your database services are vulnerable too We know that database services are critical – databases underpin IT operations in countle

Data Breach Exposes 1.6 Million Jobless Claims Filed in the Washington State

Feb 02, 2021
The Office of the Washington State Auditor (SAO) on Monday said it's investigating a security incident that resulted in the compromise of personal information of more than 1.6 million people who filed for unemployment claims in the state in 2020. The SAO blamed the breach on a software vulnerability in Accellion's File Transfer Appliance (FTA) service, which allows organizations to share sensitive documents with users outside their organization securely. "During the week of January 25, 2021, Accellion confirmed that an unauthorized person gained access to SAO files by exploiting a vulnerability in Accellion's file transfer service," the SAO  said  in a statement. The accessed information is said to have contained personal details of Washington state residents who filed unemployment insurance claims in 2020, as well as other data from local governments and state agencies. The exact information that may have been compromised include: Full name Social securi
