The Sombra ARG is an ARG involving Overwatch, a game made by Blizzard. Sombra is the name of an unreleased Overwatch hero that has been hinted at by Blizzard as being an upcoming playable character. Clues and ciphers referencing Sombra were found in various developer updates and short animations released by Blizzard, and this ARG is comprised of those clues.

At the game's release, there were numerous pieces of in-game information that appeared in Dorado, hinting at a character called Sombra. When Ana was revealed as Overwatch’s newest character, more Sombra clues appeared in Ana's origin video. In the weeks that followed, more clues were discovered.

Ana Videos

Ana Origin Video

On July 12, 2016, a video for the new Overwatch hero named Ana was released. By pausing the video at the 1:16 time mark, a bunch of hexadecimal numbers were discovered:

72 7B 20 67 78 73 72 65 2E 2E 2E 64 78 7A 75

A simple Hex to ASCII translation gave us

...{v fbr c~ryr {v ~yqxezvt~Ô¤y, c~ryr r{ gxsre...{v fbr c~ryr {v ~yqxezvt~Ô¤y, c~ryr r{ gxsre...{v fbr c~ryr {v ~yqxezvt~Ô¤y, c~ryr r{ gxsre...{v fbr       
c~ryr {v ~yqxezvt~Ô¤y, c~ryr r{ gxsre...dxzu

Using an XOR Cipher with the constant 23 on the above text, we got

..la que tiene la información; tiene el poder...la que tiene la información; tiene el poder...la que tiene la información; tiene el poder...la que tiene la  
información; tiene el poder...somb

The Spanish translates to

She who has the information, has the power...

A second frame of hexadecimal numbers was discovered at the 2:11 time mark of the video:

72 20 72 7B 20 67 78 73 72 65 2E 2E 2E

When put through the same process, the same string of Spanish was revealed, but with the letters ra at the start. These letters were combined with somb from the other cipher to create sombra, the name of an unreleased hero that has been hinted at by Blizzard in the past. This led us to believe that this ARG was related to Sombra. The ARG was named accordingly.

Dev Update Video

The vertical barcodes found at the end of the Ana Dev Update video

At the end of this video, a series of vertical barcodes were discovered. The barcodes were found to be binary, a dump of which is available here, credit of redditor /u/zapu.

Discord user Crauss turned the ones and zeroes into black and white pixels, which formed a QR code:

Sombra QR code.png

Scanning this QR code yielded the following message:

"¿Estuvo eso facilito? Ahora que tengo su atención, déjenme se las pongo más difícil." 

And translated from Sombra's native language of Spanish into English:

Was that easy? Well, now that I have your attention, allow me to make things much more difficult.

Welcome to the Summer Games Video

The base64 cipher in the Summer Games video

On August 2, another cipher was discovered in this video - this time, the ciphertext was in base64:

U2FsdGVkX1+vupppZksvRf5pq5g5XjFRIipRkwB0K1Y96Qsv2L
m+31cmzaAILwytX/z66ZVWEQM/ccf1g+9m5Ubu1+sit+A9cenD
xxqkIaxbm4cMeh2oKhqIHhdaBKOi6XX2XDWpa6+P5o9MQw==

Using a tool to decode the Base64 results in the following output:

Salted__���ifK/E�i��9^1Q�*Q�t+V=�
                                /ع��W/
                                      �_����V��?q����f�F���"��=q�������[��
                                                                          z��*����Z����u�\5�k�C

(Note: copy/pasting this string will not work; some of the characters will not paste properly)

Decrypting the Encryption

The "Salted__" header at the start of the string indicates that the remainder of the text is encoded in an OpenSSL cipher, which requires a key and a known cipher. Salts are added to encrypted data to ensure uniqueness.

Since we know the salt, and we know the input data, all we need to decrypt is the password and cipher method. Since OpenSSL has been around for ages, there are many different cipher methods.

A Cipher is a mathematical algorithm to convert data into unreadable binary data.

A Password is key to the box, if you know it you can easily decrypt the data.

Narrowing Down Ciphers

Hex view of the encrypted string

The Cipher used has been narrowed down by looking at a Hex Dump of the encrypted string. There are two major types of ciphers, stream ciphers and block ciphers. Stream ciphers encrypt only the data fed into them, whereas block ciphers will always be a set chunk length.

A byte is roughly a single character, but special characters can take up multiple bytes. We know that OpenSSL Salted Encryption uses the first 8 bytes of the output for Salted__ and the next 8 bytes for the actual salt. The rest of the information is the encrypted message.

The immediately interesting thing here is that the encrypted message data stops 3 bytes short of a full chunk. This is a excellent indicator that the cipher used is a stream cipher (or a block cipher in CTR/OFB/CFB mode). This narrows our cipher list down significantly. This also means that the final string that Blizzard encrypted is less than 93 bytes!

At the time of writing, this cipher remains unsolved; it's speculated that Blizzard moved us past the cipher by giving us hints.

Directions & Letters

There are references to directions that are present in the North American version of the video. These references are conspicuously absent from other versions of the trailer. These references are shown below, with the relevant heroes and timestamps:

Here are the screencaps, arranged according to their directions.

Dorado Photo

On the Overwatch media page, a new photo of the attacking spawn in Dorado was added. This photo was "datamoshed", which means it concealed a hidden message while also taking on a distorted appearance. (Here is an example of purposely data moshing the image manually to achieve similar effects)

After comparing the images via difference checking tools, it was found that certain English and Spanish characters were replaced with exclamation points, producing a Spanish sentence out of the replaced characters.

"Por que estan mirando al cielo? La respuesta no esta sobre sus cabezas, esta detras de ustedes. A veces, necesitan analizar sus logros previos."

Translated into English, this phrase is

"Why are you looking at the sky? The answer isn't over your heads, it's behind you. Sometimes, you need to analyze your previous achievements."

The phrase "Why are you looking at the sky?" is most likely a reference to a strange artifact that was discovered in the sky of the Dorado map, but various processes of decryption were fruitless.

Analyzing Achievements

"¿" Achievement, comment in source code

The phrase "you need to analyze your previous achievements" led us to look at the achievements on the Play Overwatch Website. We noticed that if you logged in and viewed the achievements on your player profile, a mystery achievement appeared. Viewing the source code of the image lead us to a new phrase:

Vientos, nada mal. No obstante, me aburro. Intentemos algo nuevo en la misma dirección.
uczihriwgsxorxwunaarawryqhbrsfmeqrjjmu 5552E494 78T3 4VM9 OPL6 IS8208O913KRlrx

Translated, it says:

Damn, not bad. However, I'm getting bored. Let's try something new in the same direction.
uczihriwgsxorxwunaarawryqhbrsfmeqrjjmu 5552E494 78T3 4VM9 OPL6 IS8208O913KRlrx

Volskaya Datamosh

The following instructions explain the process of how the ASCII Skull and "little games" quote were found:

1. Take the following section of code from the "?" achievement hint above.

uczihriwgsxorxwunaarawryqhbrsfmeqrjjmu 5552E494 78T3 4VM9 OPL6 IS8208O913KRlrx

2. Run it through a Vigenére Cipher

3. Use heroes in the order of their positions on the compass (further above) to get hero names for the passphrase:

tracertorbjornwinstonsymmetradvamercybastiongenjimccree

4. The code received will result in the following url which, when formatted in to a proper URL, becomes the following picture:

blzgdapiproaakamaihdnetmediascreenshot 5552E494 78B3 4CE9 ACF6 EF8208F913CFjpg
blzgdapipro-a.akamaihd.net/media/screenshot/5552E494-78B3-4CE9-ACF6-EF8208F913CF.jpg

The distortion on this picture indicates that it, too, is "datamoshed", and that it conceals hidden information. A difference check between the new and original image resulted in an interesting message.

ASCII Skull #1

The diff from the datamosh resulted in the following output:

The ASCII image of the skull seemed to be a dead end, however, as no further progress was made until August 23rd.

Overwatch Forums Glitching Page/ "Skycoder"

A Discord user named 'Majesty' was tipped towards an ominous topic on the official Overwatch forums, posted by a user named 'Skycoder.'

The name of the topic, if translated from binary, says "23"; a reference to Sombra, who is the 23rd character in Overwatch. The time posted on the forums was set at 23h and has since been counting down rather than increasing; it seems to be a countdown to something.

This topic's page soon begins to glitch and distort, turning a hue of purple before opening a text box stating:

 "la que tiene la información; tiene el poder"

and typing another code:

The code was recognized to be Base64, which was then translated to a new ASCII image:

After some cleanup, taking the difference between ASCII skulls #1 and #2 yielded these hex characters:

8F 88 96 93 95 92 90 88 97 8C 98 91 8D 98 88 8A
92 6E 6E 6E 86 95 88 92 94 98 88 98 96 97 88 87

8F 84 99 88 95 84 96 6E 8B 97 90 8F

By subtracting from each character (67 for ASCII, 64 for Symbols, Z loops from 0x40), we got:

piwtvsqixmyrnyiksgvisuyiywxihiwpswhixigxmziwhinyikswpsppeqevmeryrxvempliehfpdkheyweeqfewgepezivewlxqp

When running a Caesar Cipher and shifting by 22, the resulting string was:

lesprometiunjuegocreoqueustedeslosdetectivesdejuegoslollamarianuntrailheadblzgdausaambascalaverashtml

This translates to:

Les prometi un juego...creo que ustedes los Detectives de Juegos lo llamarían un trailhead? BLZGDUSA-AMBAS-CALAVERAS.HTML
I promised you a game...I believe you Game Detectives would call it a trailhead? BLZGDAUSA-AMBAS-CALAVERAS.HTML

"USA-AMBAS-CALAVERAS" translates to "USE-BOTH-SKULLS".

With that said, you may also notice "BLZGDAUSA-AMBAS-CALVERAS.HTML" is familiar looking. It was assumed there is a page on their CDN that contained more information, in the Skull Video section, you can see that it was true.

Skull Video

BLZGDA is Blizzard's server for hosting media, using full URL we get:

https://blzgdapipro-a.akamaihd.net/media/screenshot/usa-ambas-calaveras.html

This link leads to a video which clearly shows an image of a skull, along with a dossier of info:

6Pk69LX.png

In the video properties you can find:

Parecen estar muy interesados en estos "héroes". ¿Tal vez les interese conocer algunos detallitos que he averiguado sobre ellos?
You seem to be very interested in these "heroes". Maybe interested to know some details that I found out about them?

There is also a heartbeat monitor in the video - by looking at which lines it "pings" on, and by assigning letters to these lines, we get:

minals and bringing them to justice. These fugitives are responsible for a string of robberies, arson, and other crimes stretching from Sydney to  King's Row.
 
Authorities believe that they have set their sights on crossing the Atlantic to America.


If the timestamp-looking numbers are taken as AA:BB:CC, where AA is the number of skull, BB is the row and CC is the column (as illustrated here), the 5x5 table would look like this:

S j G B L 
. @ M O k 
i , v : 0 
E 7 r q N 
J P 5 F 1

(although, note that these symbols are the same in both skulls).

If this is used as the key for the Bifid cipher for the string below the table:

This phrase is leet-speak, when translated, it becomes

Sombra Information is power Sombra

Meanwhile, the countdown on the Blizzard forum post approached zero...

Countdown

Once the countdown on the Skycoder forum post reached zero, amomentincrime.com was updated. It now says (same colours as were in the forum post)

...Estableciendo conexiуn...
...Protocolo Sombra v1.9 iniciado...

...Transmitiendo informaciуn a уmnicos activos... 2%

A comment was added in the source code:

Bien hecho, ya tienen mi clave. Hackear este programa de televisión no tuvo chiste. Espérense a lo que sigue.

Rough translation:

Well done, you already have my key.  Hacking this TV program was not easy.  Wait for what is coming next.

The percent number seems to be slowly going up. Note that it's not updating for everybody at the same time, probably due to the caching tech employed for the amomentincrime.com.

Datamosh of Reaper

Seen on the forum post by Skycoder, during the destruction of the website itself, you can see an image fly around on the page. This image is an image of Reaper on Temple of Anubis. It is quite similar in appearance to the image sent by Muselk on Twitter as a message to Sombra, but it does appear to have minor differences.

The problem arising with this clue is that all forms of the image sent to Blizzard are compressed. The apparent original from Imgur, then a rehost by Muselk on Twitter. Imgur compresses images, along with Twitter, which destroys the original message and gives us a lot of roads to take to solve this.

Some people think Blizzard may have joked with us, that the image itself on their website is compressed to poke fun at us. But it's still potentially something.
