In Ratchet & Clank: Going Commando, there is a badly programed enemy on planet Grelbin called the Snow Beast. The enemy was made in three days and has too short of a pre-attack animation, which makes it frustrating to fight, especially in large groups. This beast was the influence for the Snow Beast Award, which is an internal award that Insomniac Games gives to the person that "Created the worst thing that actually shipped in the game" after every new game is released.

It should be noted that in the final game these 'Snow Beasts' are individually named 'Y.E.T.I.'

On December 12, 2023, a ransomware gang named Rhysida announced they they had hacked internal servers at Insomniac Games and stole upwards of 1.67 terabytes of data, including unreleased screenshots and concept art of the then-upcoming game Marvel's Wolverine, a timeline of upcoming Insomniac releases, as well as HR documents, emails, tax forms, internal conversations, and passports relating to current and former Insomniac employees, with the group posting a selection of this data as evidence of the theft. The group claimed it only took them 20-25 minutes to access the company's domain server and their motive was to publicly hold the stolen data for ransom. They offered to auction it off to anyone for 50 bitcoin, or $2 million USD, so long as the data was not resold by the new owners, with the deadline being a week from then. Reportedly 2% of the stolen data was purchased by unknown parties, but Insomniac did not purchase any of it back, leading Rhysida to release the remainder of the stolen data to the public.

In the 2023 Insomniac Games ransomware data leak, a leaked financial document revealed the development costs, sales, and shares for every game Insomniac has worked on for years. Sunset Overdrive, a 2014 Xbox and PC exclusive game co-developed by Insomniac, sold 1,898,433 units for a total of $49,737,133, but only netted the company $567 in profit after costs had been divided. This is a testament to the fact that a modern game has to sell exorbitant amounts for the development studio to make back what it often invests in creating it, possibly being an indicator of why Insomniac pivoted to making games based on financially lucrative Marvel Comics properties.
