In August 2018, Irdeto announced the Anti-Cheat technology would soon launch as a full end-to-end solution. The following year, on 20 March 2019, a launch announcement was made about the new product. According to the announcement, Denuvo Anti-Cheat combines machine learning of game agnostic process metrics with the latest hardware security features offered by Intel and AMD to detect and prevent cheating. The protection supposedly operates on the binary, not the source code, and integrates directly into the product build process, and also does not interfere with debuggers, instrumentation tools, or profilers, nor does it require additional APIs or SDKs to implement. Since it uses hardware-backed security, the protection goes beyond that which is offered by simple Windows kernel-mode drivers.
A consequence of its use of unique hardware-based code paths, Denuvo Anti-Tamper requires an online connection periodically as the system environment of the operating system changes with new hardware and/or Windows updates. While everything that might invalidate the token stored on the storage drive is not fully known, this happens frequently enough for the anti-tamper protection to be described as requiring a periodic online connection every fortnight or so. This is generally not an issue or hindrance for those with an always present online connection, but can be an annoyance for people primarily using roaming data. Players gaming offline for a long period of time can also suffer if proper preparations are not made in advance to ensure the validity of the offline token. The lack of transparency on storefronts regarding this process from Denuvo Anti-Tamper is a hindrance for potential purchasers, as it means people might not be aware of its presence and periodic online requirement before purchasing a game that, after purchase, the purchaser may find unplayable when an online connection is unavailable.
If the online connection fails the user will get a manual "offline" activation option where they can make use of a secondary online connected device to retrieve the corresponding response code, an option not available for either Origin, Uplay, or possibly other supported platforms either. The availability of this second option means a local token generator is theoretically possible for a fully offline procedure, as was confirmed in 2017 with the release of an unofficial offline token generator for Dishonored 2.
The online component relies solely on standardized HTTPS communications and a simple web API, and fully respects and makes use of system-wide proxy configuration and internet settings. Basically the client (the game executable) sends the locally generated request code in the body of a HTTP request message to the online server using the POST method, and receives the appropriate response code back in the body of the response message. This single exchange (one sent request, one received response) is all that is needed for the anti-tamper component of the game executable to generate the appropriate offline token for the system.
In August 2016, it was reported that the Denuvo protection found in DOOM had been bypassed by a cracker named Voksi. Bypasses for many other Denuvo-protected games were released the following days. Although the exploit used for these bypasses was patched 3 days after the first bypass was released, news followed that Rise of the Tomb Raider, Inside and Doom had been fully cracked by the scene group CONSPIR4CY (CPY) by successfully emulating the enhanced "v3" anti-tamper implementation and patching the remaining in-game triggers. Playdead later removed Denuvo from their game Inside in their later patches. id Software removed Denuvo from their 2016 release Doom via a patch in December later that year. Crytek later removed Denuvo from their VR game The Climb. CPY continues to crack Denuvo in other games.
This mural (1986) on handball court at 128th Street and 2nd Avenue was inspired by the crack epidemic and its effect on New York City. It was created as a warning and was initially executed independently, without City permission. The mural was immediately put under the protection and jurisdiction of the City Department of Parks and still exists. 2b1af7f3a8
