/system backup save name=encrypted-backup encryption=aes-256-cbc passphrase="YourStrongPassphrase" Note: Without the passphrase, even a patched RouterOS cannot restore this file. Never store backups on the router itself. Use:
# On a Linux machine (not on the router), use the unbinary tool: /usr/bin/unbinary yourfile.backup | grep -i "script\|add user\|http://" If you see unusual strings like /tmp/runme or suspicious IP addresses, do not restore that backup. When restoring a backup, always enable /system safemode before running: mikrotik backup patched
/import file-name=clean-config.rsc Finally, generate a fresh backup now that you are on a patched OS . When restoring a backup, always enable /system safemode
In the ever-evolving landscape of network security, few names are as trusted—and as frequently targeted—as MikroTik. With over 5 million active RouterOS devices worldwide, MikroTik is a prime target for botnet herders, ransomware gangs, and state-sponsored actors. Recently, a critical vulnerability (CVE-2024-XXXXX) surfaced, specifically targeting how the RouterOS handles user-generated backup files. RSC files are human-readable.
/system backup save name=post-patch-backup This new .backup file is generated by a patched engine and is safe for future restores. Let’s debunk some misinformation circulating on forums:
/system safemode /system backup load name=old_config.backup If the router behaves erratically, after 9 minutes safemode will auto-revert. Many admins use a "golden image" backup to deploy dozens of identical routers. However, if that golden image was created on an unpatched router, you are propagating the vulnerability. Here is the secure workflow for a patched MikroTik backup : Step 1: Export, Don't Just Backup Instead of a binary .backup (which can hide malware), use an .rsc (script) file. RSC files are human-readable.
