I’ve covered a lot of gaming disasters over the years, but I’ll be honest—waking up to discover that Rainbow Six Siege had been completely compromised wasn’t on my holiday bingo card. On December 27, 2025, one of Ubisoft’s flagship titles descended into absolute chaos when hackers breached the game’s backend systems and decided to play digital Robin Hood with the in-game economy.
If you logged into Siege during the incident window, you probably noticed something extremely wrong with your account. Two billion R6 Credits suddenly appearing in your balance? Developer-exclusive skins you’ve never seen before? Random ban messages flashing across your screen? Yeah, that wasn’t a Christmas miracle from Ubisoft—that was hackers demonstrating they had complete control over the game’s core infrastructure.

What started as confused player reports quickly escalated into one of the most significant security breaches in recent gaming history. The Rainbow Six Siege servers were hacked in a way that gave attackers administrative control over player inventories, the ban system, and the game’s economy. And the worst part? Ubisoft initially called it an “incident” rather than acknowledging the full scope of what was happening.

Key Takeaways:
- Rainbow Six Siege servers hacked on December 27, 2025, with attackers distributing approximately 2 billion R6 Credits to player accounts worldwide
- Ubisoft has shut down all Siege servers and the in-game Marketplace while implementing a full rollback of transactions since 11:00 AM UTC
- No players will be banned for spending the illegitimate credits, according to official statements
- Security researchers link the breach to the MongoBleed vulnerability (CVE-2025-14847), with claims of up to four separate hacker groups targeting Ubisoft
- Servers remain offline with no ETA for restoration as of December 28, 2025
What Happened When Rainbow Six Siege Was Hacked
The breach began around 10:00 UTC on December 27, 2025, when players across PC, PlayStation, and Xbox started reporting bizarre activity on their accounts. Within hours, the situation went from “weird glitch” to “complete system compromise.”
Here’s the breakdown of what the attackers accomplished:
| Attack Vector | Impact | Estimated Scale |
|---|---|---|
| Currency Injection | 2 billion R6 Credits distributed to accounts | ~$13.33 million in virtual currency value |
| Renown Distribution | Millions of free-to-earn currency added | All affected accounts |
| Alpha Packs | Thousands of loot boxes granted | Global distribution |
| Cosmetic Unlocks | Developer-only and Glacier skins distributed | Items normally unobtainable |
| Ban System Hijacking | Mass random bans and unbans | Thousands of accounts affected |
| Ban Feed Takeover | Custom messages broadcast globally | Visible to all online players |
ASUS Rumored to Start Making DRAM: The Truth Behind the Crazy Price Crisis The currency injection alone is staggering when you consider the numbers. Based on Ubisoft’s official pricing where 15,000 R6 Credits costs $99.99, the 2 billion credits distributed to each affected account represents roughly $13.33 million worth of premium currency—per account. Multiply that across the game’s massive player base, and you’re looking at a virtual economic catastrophe.
But the hackers didn’t stop at just flooding accounts with free stuff. They seized control of the game’s global ban feed—the ticker that normally announces when cheaters get caught—and transformed it into their personal message board. Players reported seeing ban messages containing song lyrics, holiday greetings, and pointed jabs at Ubisoft’s leadership, including references to CEO Yves Guillemot.

According to security research group VX-Underground, this breach wasn’t the work of a single attacker operating alone. Reports indicate that up to four separate hacker groups may have targeted Ubisoft simultaneously, each with different methods and motivations.
The primary exploit appears to be linked to a MongoDB vulnerability dubbed “MongoBleed,” tracked as CVE-2025-14847. This flaw allows unauthenticated attackers to extract sensitive information from exposed MongoDB database instances by sending malformed compressed packets that leak server memory. If the attackers recovered valid credentials from this memory leak, they could potentially access internal systems as if they were authorized employees.
Here’s what each group allegedly accomplished:
Group One focused on the visible chaos—the currency injections, ban system manipulation, and cosmetic distribution that players experienced directly. They gained administrative control over Rainbow Six Siege’s live service infrastructure, allowing them to modify player inventories at will.
Group Two reportedly used the MongoBleed vulnerability to pivot from an exposed database to Ubisoft’s internal Git repositories. Claims suggest they exfiltrated source code spanning from the 1990s to the present, including proprietary SDKs, multiplayer service code, uPlay infrastructure, and potentially BattlEye anti-cheat integration details. If true, this represents a massive intellectual property theft that could fuel cheat development for years.
Group Three emerged on Telegram claiming they also exploited MongoDB vulnerabilities but targeted customer and user data. This group is allegedly attempting to extort Ubisoft, though these claims haven’t been independently verified.
Group Four has accused Group Two of deception, claiming they’ve actually had access to Ubisoft’s source code for months and are using the current chaos as cover to finally leak the stolen data. This inter-hacker drama adds another layer of complexity to an already messy situation.

BleepingComputer has not been able to independently confirm the MongoBleed exploitation or the scope of any data breach beyond what affected Rainbow Six Siege directly.
Ubisoft’s Response and the Rainbow Six Siege Down Situation
Ubisoft’s initial communication left a lot to be desired. At 9:10 AM EST on December 27, the official Rainbow Six Siege X account posted a carefully worded statement acknowledging they were “aware of an incident currently affecting Rainbow Six Siege” without mentioning the words “hack,” “breach,” or “security.”
This PR-speak didn’t go over well with the community. Players immediately called out Ubisoft for what they perceived as downplaying a catastrophic security failure. Many pointed out that calling a complete backend compromise an “incident” was like calling a house fire a “temperature anomaly.”
About 30 minutes after the initial statement, Ubisoft made the decision to intentionally shut down Rainbow Six Siege servers and the in-game Marketplace. This wasn’t a crash caused by the attack—it was a deliberate containment measure to prevent further damage and stop players from potentially “laundering” the illegitimate currency through marketplace purchases.
In a follow-up update, Ubisoft provided more clarity on their recovery plans:
- No players will be banned for spending credits received during the incident
- A complete rollback of all transactions since 11:00 AM UTC is underway
- The ban ticker had been disabled in a previous update, meaning any ban messages players saw were fabricated by the attackers
- A legitimate R6 ShieldGuard ban wave did occur simultaneously but is unrelated to the breach
As of December 28, 2025, Rainbow Six Siege servers remain offline across all platforms—PC, PlayStation 4, PlayStation 5, Xbox One, and Xbox Series X|S. Ubisoft’s service status page shows all core services including authentication, matchmaking, and the in-game store in outage status. No estimated time for restoration has been provided.
Community Reaction and Streamer Warnings
The Rainbow Six Siege community’s reaction ranged from amusement to genuine concern. Some players initially celebrated their newfound billions, rushing to buy every item in the store before realizing the implications. Others were randomly banned for simply logging in—through no fault of their own.
Prominent community figures quickly stepped up to warn players about the risks. KingGeorge, the former professional player and World Champion turned streamer, issued a clear directive to his audience: “Do not log into your game, do not spend Renown, do not spend Rainbow Credits—that is my early warning to you.”
His concern wasn’t unfounded. Ubisoft has historically issued bans for exploiting glitches and unauthorized currency, even when players stumbled into situations accidentally. While Ubisoft has since clarified that no one will be punished for this incident, the initial uncertainty created legitimate anxiety among the player base.

Discord moderators echoed the warnings about not spending any credits, noting it could potentially be interpreted as a Terms of Service violation.
On Reddit and social media, the tone was a mix of dark humor and frustration. Players shared screenshots of their absurdly inflated account balances, joked about their brief stint as virtual billionaires, and created memes about the situation. But underlying the humor was genuine concern about account security, data privacy, and whether Ubisoft could actually restore normal service.
What Players Should Do Right Now
If you’re a Rainbow Six Siege player wondering what steps to take, here’s my honest advice based on everything we know:
Don’t log in until the all-clear. Even though servers are down, avoid any attempts to access the game until Ubisoft explicitly confirms the situation is fully resolved. There’s no benefit to trying, and the last thing you want is your account flagged for suspicious activity during the cleanup process.
If you logged in during the incident, don’t panic. Ubisoft has confirmed no players will be banned for receiving or even spending the distributed credits. A full rollback is in progress, which means your account will be restored to its pre-incident state. Any progress made during the chaos will be lost, but so will any illegitimate gains.
Change your Ubisoft password. While there’s no confirmed evidence that player credentials were compromised, the depth of this breach warrants precautionary measures. Update your password and ensure you’re using something unique that isn’t shared with other services.
Enable two-factor authentication. If you haven’t already, now is the time to add an extra layer of security to your Ubisoft account. This won’t help against server-side breaches, but it protects against credential theft attempts.
Consider removing stored payment information. Until the full scope of the breach is understood, removing credit card details from your Ubisoft account is a reasonable precaution. You can always add them back once the dust settles.
Watch for phishing attempts. Hackers often capitalize on chaos by sending fake “Ubisoft Support” emails asking for login credentials or payment information. Any legitimate communication from Ubisoft will come through official channels—be extremely skeptical of unsolicited messages.

This breach comes at a particularly challenging time for Ubisoft. The company has faced significant business pressures throughout 2025, including delayed earnings calls, suspended stock trading, canceled projects like a Splinter Cell game, and executive departures. A security incident of this magnitude adds another layer of concern for investors and players alike.
If the claims about source code theft prove accurate, the implications extend far beyond Rainbow Six Siege. Leaked anti-cheat integration code could compromise security across multiple Ubisoft titles. Proprietary networking code could be reverse-engineered by competitors. And the company’s intellectual property developed over three decades could end up in the hands of bad actors.
For comparison, the last major gaming security incidents of this scale were the 2011 PlayStation Network hack, which exposed data from 77 million accounts and kept PSN offline for weeks, and a Steam breach in the same year affecting 35 million users. Rainbow Six Siege’s incident appears more focused on in-game systems than personal data, but the principle remains: even major publishers with significant resources remain vulnerable to determined attackers.
PS6 Delay: AI’s RAM Hunger Could Push PlayStation 6 Past 2027 Rainbow Six Siege, now in its tenth year, has maintained a dedicated player base and active esports scene. The game had been building momentum with its recent Rainbow Six Siege X update. This breach threatens to undermine player trust at a critical moment for the franchise’s ongoing success.
Final Thoughts
The Rainbow Six Siege hack of December 2025 will likely be remembered as one of the most dramatic security incidents in gaming history—not necessarily for the damage done, but for the sheer audacity of the attack. Hackers didn’t just steal data or crash servers; they took complete control of a live game and used it to mock the company that built it while showering players with billions in virtual currency.
For now, all we can do is wait. Ubisoft’s teams are working to restore service, implement the rollback, and presumably shore up whatever vulnerabilities allowed this breach to occur. The company hasn’t provided a timeline for when Rainbow Six Siege will be back online, and given the complexity of what happened, rushing that process could create additional problems.
I’ll continue updating this article as new information emerges. If you’re a Siege player affected by this incident, hang tight—your account should be restored once Ubisoft completes the rollback. And maybe take this opportunity to finally try that single-player game you’ve been putting off. Your Siege matches will still be there when the servers come back.
Stay safe out there, and keep your passwords strong.
Frequently Asked Questions
Who is LGBTQ in Rainbow Six?
Rainbow Six Siege features several LGBTQ+ operators in its roster. Flores is an openly gay operator from Argentina who has a husband in Los Angeles. Osa is a trans woman who joined the Nighthaven team. Sens is the first non-binary operator in the franchise. Pulse has been confirmed as bisexual, while Caveira is depicted as lesbian with hints of a relationship with Twitch in Ghost Recon crossover content. Tubarão, introduced in Operation Deep Freeze, is confirmed as a transgender man. Ubisoft has worked with LGBTQ+ community members and consultants to ensure authentic representation for these characters. If you’re interested in team-based tactical games with diverse representation, you might also enjoy checking out other cooperative shooters like Cloudheim that feature unique character designs.
Is Rainbow Six Siege bad for a 13 year old?
Rainbow Six Siege carries an M (Mature 17+) rating from the ESRB and PEGI 18 in Europe, primarily due to realistic violence, blood effects, drug references (cocaine visible on in-game tables), and strong language including use of the F-word in dialogue. The game depicts tactical counter-terrorism operations with firearms, explosives, and hostage scenarios. Player reviews on Common Sense Media suggest the game may be suitable for mature teens around 12-15 with parental guidance and supervision, but this depends entirely on the individual child’s maturity level. Parents should also consider the online multiplayer nature of the game, where voice chat can expose players to toxic behavior and inappropriate language from strangers. If you’re looking for alternatives, Rainbow Six Extraction offers a cooperative alien-fighting experience with less realistic violence and is rated for ages 13+.
Is Rainbow Six Siege newbie friendly?
Honestly? Rainbow Six Siege has one of the steepest learning curves in competitive gaming. Unlike run-and-gun shooters, Siege requires extensive map knowledge, operator ability memorization, and tactical coordination. New players will need to learn destructible environment mechanics, drone usage, camera systems, and the unique gadgets of 60+ operators. The game punishes rushing and rewards patience and communication. That said, Ubisoft has implemented various features to help newcomers, including training modes, newcomer playlists, and the recent Siege X update improvements. Most veteran players suggest dedicating significant time to learning maps and watching content creators before expecting to be competitive. For players who enjoy tactical shooters but want something slightly more accessible, games with clear objective markers and straightforward combat systems like Arc Raiders might serve as good entry points into the genre.
How much is $100 in R6 credits?
Based on Ubisoft’s official store pricing, $99.99 USD gets you 15,000 R6 Credits—so roughly $100 equals 15,000 credits. The credit packs scale with better value at higher amounts: smaller packs like 1,200 credits cost around $9.99, while mid-tier options like 7,200 credits run approximately $49.99. R6 Credits are the premium currency used to purchase operators (600 credits each for seasonal operators), Battle Pass access (1,200 credits), Elite sets, weapon skins, headgear, uniforms, and charms. For perspective on the hack’s scale, the 2 billion R6 Credits distributed to each affected account would be worth approximately $13.33 million per account at standard pricing.
