38 Instagram Plaintext Passwords Dumped on Telegram

HEROIC analysts detected a stealer log file targeting Instagram accounts that was shared on Telegram in May 2026. The dump contained 38 compromised records, each consisting of an email address, a plaintext password, and the Instagram login URL. These credentials were harvested by infostealer malware running on infected devices, capturing login details as users accessed their Instagram accounts.

Why Plaintext Instagram Passwords Open the Door to Identity Theft

Instagram accounts contain far more than photos. They hold personal messages, contact information, linked phone numbers, and connections to other social platforms. When an Instagram password leaks in plaintext, attackers gain immediate access to all of this personal data without needing to crack any encryption.

Compromised Instagram accounts are frequently used for impersonation scams, where attackers message the victim's contacts to request money or spread malicious links. The trusted nature of a friend's account makes these scams highly effective.

Beyond social engineering, stolen Instagram credentials are often reused across other platforms. If a victim uses the same password for their email, banking, or work accounts, one leaked Instagram login becomes the key to a much wider breach.

What Was Exposed in the Instagram Dump

• Email Addresses — Email addresses associated with Instagram accounts
• Plaintext Passwords — Unencrypted Instagram login passwords ready for immediate use
• URLs — Instagram login page URLs confirming the target service

Why 38 Stolen Instagram Logins Should Not Be Underestimated

Each of these 38 records represents a real Instagram account that an attacker can access immediately. While the number may seem small, the impact per compromised account is significant. Attackers can lock victims out of their own accounts, harvest personal photos and messages for blackmail, or use the account as a launchpad for further attacks.

Instagram account takeovers are also valuable on underground markets. Accounts with established followings, verified status, or business profiles can be sold to spammers, scammers, or competitors for prices ranging from a few dollars to hundreds depending on the account's reach.

The 38 affected users may also find their credentials bundled into larger combo lists, where they are tested against hundreds of other services through automated credential stuffing attacks.

How Stealer Logs Compromise Social Media Accounts

Infostealer malware targets saved passwords in web browsers, which is how most people log into Instagram. Malware variants like RedLine, Raccoon, and Aurora extract stored credentials from Chrome, Firefox, Edge, and other browsers, then package them into log files organized by service URL.

The infection typically begins with a deceptive download: a pirated game, a fake software update, or a phishing email with a malicious attachment. Once executed, the malware runs silently in the background, transmitting harvested credentials to attacker-controlled servers within minutes.

Instagram's own security measures, including two-factor authentication and suspicious login alerts, can mitigate the damage, but only if the victim has enabled them before the theft occurs. Without these safeguards, attackers can change the account's email and password to permanently lock out the rightful owner.

Check If Your Instagram Credentials Were Exposed

If you use Instagram and have ever saved your password in a web browser, your credentials could be at risk from this or similar stealer log dumps. Changing your Instagram password immediately and enabling two-factor authentication are essential first steps.

Use the HEROIC data breach scanner to search across more than 400 billion compromised records. You can check whether your email address or password appeared in this Instagram-targeted leak or any other known breach, and take action to secure your accounts before someone else uses them.
