Adobe’s 2013 data breach exposed 153 million user accounts — including email addresses, encrypted passwords, and password hints stored in plain text. It was one of the largest breaches in internet history. But Adobe has fundamentally changed its security infrastructure since then, and the platform is safe to use in 2026.

What happened in the Adobe data breach?
In October 2013, Adobe disclosed that hackers had broken into its systems and stolen a massive database of user information. The initial announcement said 2.9 million accounts were affected, but the true number turned out to be 153 million — making it one of the largest data breaches ever recorded at the time. Security journalist Brian Krebs was among the first to reveal the true scale of the breach; his original KrebsOnSecurity reporting on the Adobe breach documents how the damage unfolded.
The stolen data included email addresses, encrypted passwords, password hints, and usernames. Adobe also confirmed that source code for several of its products, including ColdFusion and Acrobat, was stolen in the same attack.
What made this breach particularly damaging was how Adobe stored passwords. Instead of using proper password hashing (a one-way process that makes passwords extremely difficult to reverse), Adobe encrypted passwords using 3DES in ECB mode. This is a symmetric encryption method, which means the same password always produces the same encrypted output.
This flaw allowed security researchers — and attackers — to identify common passwords by looking for repeated patterns in the encrypted data. If 2 million accounts all had the same encrypted password, that password was almost certainly “123456.” Making matters worse, password hints were stored in completely plain text. So even when the encrypted password was not immediately crackable, the hint often gave it away.
As of 2026, over 9 billion records have been exposed across all known breaches worldwide, and the Adobe breach remains one of the most referenced examples of poor password storage practices. The IBM Cost of a Data Breach Report 2024 found the average cost of a data breach reached $4.88 million USD — highlighting why organisations now invest heavily in preventative security.
Is Adobe safe to use now?
Yes, Adobe is safe to use in 2026. The company has completely overhauled its security infrastructure since 2013.
Adobe moved from its old on-premises systems to a modern cloud-based model with Adobe Creative Cloud. This was not just a branding change — it involved rebuilding the authentication and data storage systems from the ground up. Passwords are now stored using industry-standard hashing algorithms rather than the flawed 3DES encryption that was exploited in 2013.
Adobe also introduced two-factor authentication, improved its security monitoring systems, and established a dedicated security response team. The company regularly publishes security bulletins and has an active bug bounty program that pays researchers to find vulnerabilities before attackers can exploit them.
The shift to cloud-based subscriptions also means that Adobe’s security updates are applied automatically, rather than relying on users to download patches — which reduces the window of vulnerability for security flaws in Adobe products.
What did Adobe do to fix the security problems?
After the breach, Adobe took several significant steps:
- Forced password resets for all affected accounts
- Replaced 3DES encryption with proper password hashing using industry-standard algorithms that are resistant to the pattern-matching attacks that broke the 2013 encryption
- Eliminated plain text password hints — these are no longer stored or requested
- Added two-factor authentication across all Adobe ID accounts
- Migrated to cloud-based infrastructure with modern security controls, encryption in transit, and encryption at rest
- Created a dedicated security incident response team and expanded security monitoring across all Adobe services
- Launched a bug bounty program to incentivize external security researchers to find and report vulnerabilities responsibly
Adobe also reached a settlement with affected users and paid $1.1 million in legal fees and an undisclosed amount in damages related to the breach.
How to check if your Adobe data was exposed
The Adobe breach happened in 2013, but that data is still circulating on dark web marketplaces and underground forums. If you had an Adobe account back then, your information may still be out there.
Check your email now with EmailLeaked — it scans billions of records from known data breaches, including the 2013 Adobe breach, and tells you instantly if your email was exposed. The check is free and takes just seconds.
Even if your Adobe password has been changed since 2013, knowing which breaches your email appeared in helps you understand your overall risk and whether you might be vulnerable to credential stuffing attacks.
5 steps to secure your Adobe account right now
Whether or not you were affected by the 2013 breach, these steps will help keep your Adobe account secure.
Step 1: Change your password. Log in to your Adobe account at account.adobe.com, go to Security and Privacy, and change your password. Use at least 16 characters, make it completely unique to Adobe, and avoid anything based on personal information. A password manager makes this simple.
Step 2: Enable two-factor authentication. In the same Security and Privacy section, turn on two-step verification. Adobe supports authenticator apps and SMS verification. Choose the authenticator app option for stronger security. Learn more about why two-factor authentication matters.
Step 3: Check your connected applications. Review which apps and services are connected to your Adobe ID. Remove any you no longer use — each connection is a potential entry point if that third-party service gets breached.
Step 4: Review your Adobe subscription details. Make sure your payment information and account recovery email are correct and up to date. If an attacker gains access to your Adobe account, outdated recovery information can make it harder for you to regain control.
Step 5: Use a unique password for every service. If you were using the same password for Adobe and other services back in 2013, those other accounts are also at risk. Attackers routinely test leaked credentials against other platforms — a technique called credential stuffing. Change any reused passwords immediately.
The bottom line
The 2013 Adobe breach was a textbook example of what goes wrong when passwords are not stored properly. But Adobe has learned from that incident and rebuilt its security from the ground up. With modern password hashing, two-factor authentication, and cloud-based infrastructure, Adobe in 2026 is a very different platform from the one that was breached in 2013.
Your main concern should not be Adobe’s current security — it should be whether your old Adobe password was reused on other sites. Check if your email was exposed, change any reused passwords, and enable two-factor authentication on every account that supports it.
