Core Elastic Stack Security Features Now Available For Free Users As Well

Core Elastic Stack Security Features Now Available For Free Users As Well

May 21, 2019Wang Wei
Elastic, the company behind the most widely used enterprise search engine ElasticSearch and the Elastic Stack, today announced that it has decided to make core security features of the Elastic Stack free and accessible to all users. ELK Stack or Elastic Stack is a collection of three powerful open source projects—Elasticsearch, Logstash, and Kibana—that many large and small companies are using to format, search, analyze, and visualize a large amount of data in real time. In recent months, we have seen how thousands of instances of insecure, poorly configured Elasticsearch and Kibana servers had left millions of users sensitive data exposed on the Internet. Since the free version of Elastic Stack by default does not have any authentication or authorization mechanism, many developers and administrators fail to properly implement important security features manually. The core security features—like encrypted communication, role-based access control, authentication realms—in p
Over 202 Million Chinese Job Seekers' Details Exposed On the Internet

Over 202 Million Chinese Job Seekers' Details Exposed On the Internet

January 10, 2019Wang Wei
Cybersecurity researcher has discovered online a massive database containing records of more than 202 million Chinese citizens that remained accessible to anyone on the Internet without authentication until last week. The unprotected 854.8 gigabytes of the database was stored in an instance of MongoDB, a NoSQL high performance and cross-platform document-oriented database, hosted by an American server hosting company. In total, the database contained 202,730,434 records about job candidates from China, including candidates' personal information such as their full name, date of birth, phone number, email address, marriage status, and driver’s license information, along with their professional experience and job expectations. Bob Diachenko, director of cyber risk research at Hacken.io and bug bounty platform HackenProof, discovered the existence of database two weeks ago, which had been secured shortly after his notification on Twitter. However, it is worth noting that &
Insecure Hadoop Clusters Expose Over 5,000 Terabytes of Data

Insecure Hadoop Clusters Expose Over 5,000 Terabytes of Data

June 03, 2017Swati Khandelwal
Until last year, cyber criminals were only targeting computers of individuals and organisations with ransomware and holding them for ransom, but then they started targeting unprotected online databases and servers around the globe for ransom as well. Earlier this year, we saw notorious incidents where tens of thousands of unprotected MongoDB and Elasticsearch databases were hacked and held for ransom in exchange of the data the hackers had stolen and deleted from the poorly configured systems. Now, cyber crooks have started targeting unprotected Hadoop Clusters and CouchDB servers as well, making the ransomware game nastier if your servers are not securely configured. Nearly 4,500 servers with the Hadoop Distributed File System (HDFS) — the primary distributed storage used by Hadoop applications — were found exposing more than 5,000 Terabytes (5.12 Petabytes) of data, according to an analysis conducted using Shodan search engine. This exposure is due to the same issue — H
Someone Hijacking Unsecured MongoDB Databases for Ransom

Someone Hijacking Unsecured MongoDB Databases for Ransom

January 04, 2017Swati Khandelwal
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
