While Blizzard remains silent about the details of the highly anticipated expansion of "Overwatch," speculations claim that the upcoming DLC will introduce Sombra as the game's newest playable character in November based on the freshly leaked image.

Reports claim that Sombra's newest hacking attack, leaked on the game's Subreddit page, could be a hint that the character will be revealed as the latest playable character from the team-based first-person shooter game.

According to Engadget, the leaked image could be the game developer's tactic to garner more interest about the character until they can unveil the DLC during the upcoming BlizzCon 2016 on Nov. 4 to Nov. 5.

The character was first teased at Blizzard's official website when an image signed by the game developer's senior concept artist, John Polidora, was posted, but it was soon taken down. However, the image once again appeared on Reddit. This could be another clue that the DLC will be definitely mentioned in the upcoming BlizzCon 2016 event.

Another clue about the possible Sombra DLC was posted on the game's official website when a news article from the "Overwatch" universe revealed that the fictional energy company LumeriCo is being rocked by a major scandal after Sombra and her group obtained confidential documents through hacking.

Based on the pieces of evidence found by Sombra, LumeriCo CEO Guillermo Portero is using the company's funds for his own personal purposes. While Portero denied that validity of the documents, Sombra's efforts gained her a number of supporters like the Los Muertos. The group demands Portero to immediately resign from his post and pay for his crimes in prison.

However, Blizzard has yet to reveal if the news that happened in the in-game universe has a connection with the game's upcoming DLC.

The game developer is also expected to shed more light about the rumored "Overwatch" DLC in the company's upcoming video game conference.
