So it was plain nothing. I opened my MBP, resuming it from sleep mode. I signed off, and tried to sign back in. Entering password — it does nothing. Repeated it — nothing.  Entering wrong password so many times — my Mac doesn't get locked. I sign in as a Guest, then sign off. I signed in successfully in Logon screen, but as soon as I signed on, another window appeared telling me to enter password (like when you exit sleep), just saying "Guest user". I repeated, signed in. My desktop image changed to solid color. Then, Mac screenshoted itself and set the screenshot to desktop image. Then I forced shut off, in case that it's a problem.

Do those symptoms mean that hackers got access to my Mac? What can I do if yes?

    What backups do you have?

    If you want to preserve the data on the boot drive, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data, you can skip this step.

    There are several ways to back up a Mac that is unable to fully boot. You need an external hard drive to hold the backup data.

    1. Boot into Recovery (command-R at startup) or from a local Time Machine backup volume (option key at startup.) Launch Disk Utility and follow the instructions in the support article linked below, under “Instructions for backing up to an external hard disk via Disk Utility.”

    2. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode by holding down the key combination command-T at the startup chime. Connect the two Macs with a FireWire or Thunderbolt cable. The internal drive of the machine running in target mode will mount as an external drive on the other machine. Copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.

    3. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
