Ransomware Now Attacking MySQL Databases

Early this year, specialists cautioned of a spike in quantity of attacks against MongoDB frameworks, criminals asked for the payment of a ransom to return information and help the organization to settle the defect they abused.

So also to the MongoDB attacks, owners are told to pay a 0.2 Bitcoin to deliver (approx. $200) to recover access to their content.

Attack Summary

Investigators from guardicore reported that attacks began at midnight at 00:15 on February 12 and kept going around 30 hours in which many attacks were accounted for by GGSN.

The attack begins with “root” password brute-forcing. Once signed in, it brings a rundown of the current MySQL databases and their tables.

Then it makes another table called “WARNING” that incorporates a contact email address, a bitcoin address, and a payment demand.

Investigators traced down the source IP 109.236.88.20, an IP address hosted by worldstream.nl, a Netherlands-based web hosting organization.

The attacker is (likely) running from a compromised mail server which additionally fills in as HTTP(s) and FTP server.

Attack Variants

  • In one variation of the attack, the table is added to a current database.
  • In Another variation, the table is added to a recently made database called ‘PLEASE_READ‘.
INSERT INTO PLEASE_READ.`WARNING`(id, warning, Bitcoin_Address, Email)
VALUES(‘1′,’Send 0.2 BTC to this address and contact this email
with your ip or db_name of your server to recover your database!
Your DB is Backed up to our servers!’,
‘1ET9NHZEXXQ34qSP46vKg8mrWgT89cfZoY’, ‘[email protected]’)
INSERT INTO `WARNING`(id, warning)

Ransomware Now Attacking MySQL Databases

As there are no traces for dump operation or data exfiltration happened.

Experts from guardicore before paying the ransom we strongly encourage you to verify that the attacker actually holds your data and that it can be restored.

Prevention method suggested by Experts

Every MySQL server facing the internet is prone to this attack, so make sure your servers are hardened.

Also, make sure your servers require authentication and that strong passwords are in use. Minimizing internet facing services, particularly those containing sensitive information is also a good practice.

Monitoring your internet accessible machines/services is crucial to being able to rapidly respond to any breach. This can be easily achieved using GuardiCore Centra.
