Ah, the age-old tale of leaving the front door wide open and being surprised when uninvited guests throw a party in your living room. According to a recent report, over 1,500 PostgreSQL servers were compromised in a fileless cryptocurrency mining campaign. The Hacker News

Here’s the gist:

• Publicly-exposed PostgreSQL instances: These servers were accessible to the internet without proper safeguards.​
• Weak or predictable credentials: Using passwords like “password123” or “admin” is akin to locking your door with a piece of string.​
• Abuse of the COPY ... FROM PROGRAM SQL command: This nifty feature was exploited to execute arbitrary shell commands on the host.​
• Fileless execution of cryptocurrency miners: The attackers ran mining operations directly in memory, leaving minimal traces.​

Hugh’s Hot Take:

If you’re running a PostgreSQL server that’s exposed to the internet, please:

1. Use strong, unique passwords: Your pet’s name followed by “123” doesn’t cut it.​
2. Disable the COPY ... FROM PROGRAM command if not needed: It’s like having a self-destruct button—don’t make it easy to press.​
3. Regularly update and patch your systems: Outdated software is an open invitation for trouble.​

Remember, in the grand chess game of cybersecurity, don’t be the player who leaves their king wide open. Protect your servers, or the only thing they’ll be serving is someone else’s crypto wallet.

P.S.: If your server starts overheating and you haven’t installed any new applications, maybe it’s time to check for unexpected “guests.”
