Synology NAS is a multi-functional Network-Attached Storage server, serving as a file-sharing center within your Intranet. Moreover, it is specially designed for a variety of purposes, allowing you to perform the following tasks with the web-based Synology DiskStation. Synology gives you a free synology.me DDNS hostname but you are free to use your own hostname or even a free service like DuckDNS. I have a tutorial for setting up DuckDNS and will be utilizing a free DuckDNS hostname in this tutorial, but the process is the same for other DDNS hostnames or purchased domains. Aug 01, 2019 Synology is warning NAS owners of several ransomware attacks that hit some users recently. The attackers use brute-force methods to guess the default password—essentially, they try every password possible until they get a match.

If you have a Synology NAS and had some sort of disk crash in the past, you've probably encountered the famous 'Cannot format system partition' and 'Please configure your router to forward port 23 to DiskStation and contact Synology online support'.

Yeah, it sucks.

It sucks even more when you know the disk is perfectly fine, and you still have hopes to recover your data. Or you simply don't like the idea of having your port 23 open to the world for god-knows-how-long until a Synology tech support can look into your case.

You've probably tried telneting to your NAS. Maybe you've even tried opening the case and hacking the serial port, only to discover that you don't have the root password. The DS Assistant password doesn't work, and you exhausted all obvious guesses - blank, synopass, synology, password, admin, root, etc.

Well, what about c12-0804? No, I didn't make this up. This is today's password.

I try to convert Markdown files to PDF with FOR%%i IN (.md) DO pandoc '%%fi' -o '%%dpni.pdf' -template=weber-export.tex -pdf-engine=xelatex But it wont convert. On Windows systems, for Pandoc version above 2.0, you can use the following command to generate the PDF file: pandoc -pdf-engine=xelatex -V CJKmainfont='KaiTi' test.md -o test.pdf In the above command, KaiTi is the name of a font which supports the Chinese characters. How do we find a font supporting a particular language? Pandoc convert md to pdf. From markdown to PDF: pandoc MANUAL.txt-pdf-engine=xelatex -o example13.pdf; PDF with numbered sections and a custom LaTeX header. Pandoc example15.md-o. Pandoc -s -o doc.pdf doc.md Pandoc is able to merge multiple Markdown files into a single PDF document. To generate a single PDF document out of two Markdown files you can use: pandoc -s -o doc.pdf part01.md part02.md. Pandoc file.md -o output.pdf -f markdown-implicitfigures Ugly code blocks Using Eisvogel can output beautiful code blocks by the command below after installing the template.

But if you're reading this a few days (or years) from now, too bad; it won't work. Unless, of course, you wait until December 8th. Because the password repeats every year.

Basically Synology hardcoded a modified login binary within the firmware that accepts an obfuscated password for root, which depends on the current date. (by the way, this isn't the only thing Synology folks hardcoded in the firmware).

Thanks to GPL, Synology was forced to publish the original source code for the firmware. Based on the original correct_password.c code, I hacked a short snippet to generate the daily password.

Here's the Synology Telnet password generator:

Compile and run the code above with gcc. You can also use the excellent CodepadRepl.it to run the code online and get the password for today (no registration needed).

Bonus tip: if you're curious how exactly the password is generated, here's the algorithm:

• 1st character = month in hexadecimal, lower case (1=Jan, .. , a=Oct, b=Nov, c=Dec)
• 2-3 = month in decimal, zero padded and starting in 1 (01, 02, 03, .., 11, 12)
• 4 = dash
• 5-6 = day of the month in hex (01, 02 ., 0A, ., 1F)
• 7-8 = greatest common divisor between month and day, zero padded. This is always a number between 01 and 12.

So, let's say today is October 15, the password would be: a10-0f05 where a = month in hex, 10 = month in decimal, 0f = day in hex, 05 = greatest divisor between 10 and 15).

If you have trouble calculating the greatest common divisor (elementary math, anyone?), Wolfram Alpha is your friend.

This was tested on a Synology DS212+, with Marvell Kirkwood mv6282 chipset. It's unlikely but still possible that different models use a different algorithm. YMMV, so always check the source code.

[UPDATE 1: Several users reported that this works in many other models, including DS409, DS112j, etc. Please leave a comment with your model and firmware version.]

[UPDATE 2: If it doesn't work, it's probably that your date is incorrect in the NAS. Per Patrick's suggestion below, try '101-0101', which is the password for Jan 01]

I received this comment on my article on how to reset the synology password article last week:

“Hello! Very interesting article and very interesting blog.
In DSM I have recently seen an option:
Control Panel —> Update & Restore —> Reset —> Reset Option
There is an option to tick:
“Keep current admin password unchanged”
With the following explanation:
“You can keep the current admin password unchanged if you press and hold the RESET button on your DiskStation for 4 seconds for system reset”.

Does it mean that if I tick this option and in the future I will forget the admin password I will be locked out my Synology even if I will press the reset button for 4 seconds? The DSM help doesn’t mention this option and I couldn’t find info of it on the internet. Thanks again.”

Reset Option on your Synology

1password Synology Nas

I wasn’t aware that the option was there, but after I checked my synology, there it is:

1. Control Panel
2. Update & Restore
3. Reset
4. Keep your admin password unchanged

Dubstep software free download for mac. So, what does that mean?

I googled it and I couldn’t find anything, so there was only one thing left to do: try to do some thinking of my own 😉

So, what is going on? Why and when would you not want to be able to recover your password?

And then it hit me: what if somebody breaks in your office or home?

The dangerous back door….

1password Synology Chrome Extension

So if a thief breaks into your office or home, and knows a little bit about synologies, to be able to get access to all your files and the system, the only thing they need to do is to press the reset button.

Suddenly what it was a great feature it is a huge security risk.

So all my synologies have now that option ticked. If they break into my office I wont make it that easy for them to steal my data and I recommend you do the same.

Suggestion to synology

This is a big flaw in the synology system. Download java for mac os sierra. The design of this feature is flawed and dangerous.

This is a suggestion to synology to improve this.

I forgot my password or the admin left the company or….you know, you need the admin password, then yes, reset the password, but before you can access it again, you need to go through the 2-step authentication, so if they want to get my data, they need to steal my NAS and my phone. Not impossible, but harder to do.

Next post it will be on the configuration series and I will talk about moving files to your brand new synology.
