WARNING: Hackers Install Secret Backdoor on Thousands of Microsoft SQL Servers

WARNING: Hackers Install Secret Backdoor on Thousands of Microsoft SQL Servers

April 01, 2020Ravie Lakshmanan
Cybersecurity researchers today uncovered a sustained malicious campaign dating back to May 2018 that targets Windows machines running MS-SQL servers to deploy backdoors and other kinds of malware, including multi-functional remote access tools (RATs) and cryptominers. Named " Vollgar " after the Vollar cryptocurrency it mines and its offensive "vulgar" modus operandi, researchers at Guardicore Labs said the attack employs password brute-force to breach Microsoft SQL servers with weak credentials exposed to the Internet. Researchers claim the attackers managed to successfully infect nearly 2,000-3,000 database servers daily over the past few weeks, with potential victims belonging to healthcare, aviation, IT & telecommunications, and higher education sectors across China, India, the US, South Korea, and Turkey. Thankfully for those concerned, researchers have also released a script to let sysadmins detect if any of their Windows MS-SQL servers have been
Stealthy Microsoft SQL Server Backdoor Malware Spotted in the Wild

Stealthy Microsoft SQL Server Backdoor Malware Spotted in the Wild

October 22, 2019Wang Wei
Cybersecurity researchers claim to have discovered a previously undocumented backdoor specifically designed for Microsoft SQL servers that could allow a remote attacker to control an already compromised system stealthily. Dubbed Skip-2.0 , the backdoor malware is a post-exploitation tool that runs in the memory and lets remote attackers connect to any account on the server running MSSQL version 11 and version 12 by using a "magic password." What's more? The malware manages to remain undetected on the victim's MSSQL Server by disabling the compromised machine's logging functions, event publishing, and audit mechanisms every time the "magic password" is used. With these capabilities, an attacker can stealthily copy, modify, or delete the content stored in a database, the impact of which varies from application to application integrated with targeted servers. "This could be used, for example, to manipulate in-game currencies for financial gai

Hackers Targeting Servers Running Database Services for Mining Cryptocurrency

Security researchers have discovered multiple attack campaigns conducted by an established Chinese criminal group that operates worldwide, targeting database servers for mining cryptocurrencies, exfiltrating sensitive data and building a DDoS botnet. The researchers from security firm GuardiCore Labs have analyzed thousands of attacks launched in recent months and identified at least three attack variants— Hex, Hanako, and Taylor —targeting different MS SQL and MySQL servers for both Windows and Linux. The goals of all the three variants are different—Hex installs cryptocurrency miners and remote access trojans (RATs) on infected machines, Taylor installs a keylogger and a backdoor, and Hanako uses infected devices to build a DDoS botnet. So far, researchers have recorded hundreds of Hex and Hanako attacks and tens of thousands of Taylor attacks each month and found that most compromised machines are based in China, and some in Thailand, the United States, Japan and others.
