600TB MongoDB Database 'accidentally' exposed on the Internet

600TB MongoDB Database 'accidentally' exposed on the Internet

Jul 22, 2015
System administrators have reportedly exposed almost 600 Terabytes (TB) of MongoDB database due to running outdated and unpatched versions of the NoSQL MongoDB database. The open source MongoDB is the most popular NoSQL database used by companies of all sizes, from eBay and Sourceforge to The New York Times and LinkedIn. According to Shodan's representative John Matherly, nearly 30,000 MongoDB instances are publicly accessible over the Internet without the need of any form of authentication. This huge MongoDB database isn't exposed due to a flaw in its latest version of the software, but due to the use of out-of-date and unpatched versions of the platform that fail to bind to localhost. While investigating NoSQL databases, Matherly focused on MongoDB that is growing in popularity. "It turns out that MongoDB version 2.4.14 seems to be the last version that still listened to 0.0.0.0 [in which listening is enabled for all interfaces] by default, which ...
Over 27,000 MongoDB Databases Held For Ransom Within A Week

Over 27,000 MongoDB Databases Held For Ransom Within A Week

Jan 09, 2017
The ransomware attacks on poorly secured MongoDB installations have doubled in just a day. A hacker going by the handle Harak1r1 is accessing, copying and deleting unpatched or badly-configured MongoDB databases and then threatening administrators to ransom in exchange of the lost data. It all started on Monday when security researcher Victor Gevers identified nearly 200 instances of a MongoDB installation that have been erased and held for ransom , asking victims to pay hefty ransoms for the data to be restored. By Tuesday, this number reached approximately 2,000 databases as reported by Shodan Founder John Matherly, and by Friday, Gevers and fellow security researcher Niall Merrigan updated this count to 10,500. However, according to recent statistics compiled by Merrigan, the number of compromised systems have reached more than double to 27,000, over the course of about 12 hours. What's worse? Initial attacks saw ransoms of 0.2 Bitcoins (nearly US$184) to the ...

MongoDB Vulnerability CVE-2025-14847 Under Active Exploitation Worldwide

MongoDB Vulnerability CVE-2025-14847 Under Active Exploitation Worldwide

Dec 29, 2025 Database Security / Vulnerability
A recently disclosed security vulnerability in MongoDB has come under active exploitation in the wild, with over 87,000 potentially susceptible instances identified across the world. The vulnerability in question is CVE-2025-14847 (CVSS score: 8.7), which allows an unauthenticated attacker to remotely leak sensitive data from the MongoDB server memory. It has been codenamed MongoBleed . "A flaw in zlib compression allows attackers to trigger information leakage," OX Security said . "By sending malformed network packets, an attacker can extract fragments of private data." The problem is rooted in MongoDB Server's zlib message decompression implementation ("message_compressor_zlib.cpp"). It affects instances with zlib compression enabled, which is the default configuration. Successful exploitation of the shortcoming could allow an attacker to extract sensitive information from MongoDB servers, including user information, passwords, and API keys. ...
40,000 UnProtected MongoDB Databases Found on the Internet

40,000 UnProtected MongoDB Databases Found on the Internet

Feb 12, 2015
Nearly 40,000 organisations running MongoDB , a NoSQL high performance and cross-platform document-oriented database, are found to be unprotected and vulnerable to hackers. Three students from University of Saarland in Germany at the Centre for IT Security – Kai Greshake, Eric Petryka and Jens Heyens – discovered that MongoDB databases running at TCP port 27017 as a service on several thousands of commercial web servers are easily accessible on the Internet. MongoDB is an open-source database used by companies of all sizes, across all industries for a wide variety of applications. MongoDB is built for scalability, performance and high availability, scaling from single server deployments to large, complex multi-site architectures. By leveraging in-memory computing, MongoDB provides high performance for both reads and writes. The German researchers said that they were able to get "read and write access" to the unsecured MongoDB databases without using any sp...
MongoDB Suffers Security Breach, Exposing Customer Data

MongoDB Suffers Security Breach, Exposing Customer Data

Dec 17, 2023 Cyber Attack / Data Security
MongoDB on Saturday disclosed it's actively investigating a security incident that has led to unauthorized access to "certain" corporate systems, resulting in the exposure of customer account metadata and contact information. The American database software company  said  it first detected anomalous activity on December 13, 2023, and that it immediately activated its incident response efforts. It further noted that "this unauthorized access has been going on for some period of time before discovery," but emphasized it's not "aware of any exposure to the data that customers store in MongoDB Atlas." It did not disclose the exact time period of the compromise. In light of the breach, MongoDB recommends that all customers be on the lookout for social engineering and phishing attacks, enforce phishing-resistant multi-factor authentication (MFA), as well as rotate their MongoDB Atlas passwords. That's not all. The company said it's also expe...
Someone Hijacking Unsecured MongoDB Databases for Ransom

Someone Hijacking Unsecured MongoDB Databases for Ransom

Jan 04, 2017
Nearly two years back, we warned users about publicly accessible MongoDB instances – almost 600 Terabytes (TB) – over the Internet which require no authentication, potentially leaving websites and servers at risk of hacking. These MongoDB instances weren't exposed due to any flaw in its software, but due to a misconfiguration (bad security practice) that let any remote attacker access MongoDB databases without using any special hacking tool. MongoDB later resolved the issue in the next version of its software by setting unrestricted remote access by default in the configuration, thousands of site administrators have not updated their servers yet. But trust me, they'll now regret this! A Hacker is now hijacking and wiping out unsecured MongoDB databases , but keeping a copy of those databases for asking administrators a ransom of 0.2 Bitcoins (nearly US$211) to return the lost data. So, admins without backups are left in a bind. In fact, the rising price of Bitcoin...
