Panera Bread has been named by the cybercrime group ShinyHunters as the newest sufferer in a large-scale stolen credentials incident.
This raises recent issues in regards to the safety of single sign-on techniques and the rising effectiveness of social engineering assaults focusing on main client manufacturers.
The group claims it obtained delicate buyer information linked to Panera Bread and has listed the corporate on its information leak website alongside different high-profile organizations. Whereas Panera Bread has not publicly confirmed the breach, the allegations level to the publicity of thousands and thousands of buyer data and spotlight a wider marketing campaign that safety researchers say is affecting firms throughout a number of sectors.
Alleged information theft

The dataset allegedly consists of names, e-mail addresses, postal addresses, telephone numbers, and account-related particulars.

Whereas there is no such thing as a indication that fee card information or passwords had been included, the kind of private data described may nonetheless be used for phishing, identification fraud, and account takeover makes an attempt.
Cybersecurity consultants routinely warn that giant troves of fundamental buyer information may be simply as beneficial to criminals as monetary particulars, particularly when mixed with data obtained from different breaches.
SSO underneath scrutiny
ShinyHunters instructed The Register that it gained entry to Panera Bread’s techniques by Microsoft Entra single sign-on. If confirmed, this could align the incident with a broader wave of assaults focusing on identification and entry administration platforms moderately than particular person purposes.
SSO techniques are extensively utilized by giant organizations to simplify worker entry throughout a number of companies. Nonetheless, compromising a single set of credentials or authentication stream can doubtlessly present attackers with broad inner entry.
The alleged Panera Bread breach comes shortly after Okta warned that risk actors had been actively focusing on SSO platforms operated by Okta, Microsoft, and Google utilizing subtle voice phishing, or “vishing,” strategies. These assaults sometimes contain impersonating IT employees or trusted service suppliers to trick workers into sharing authentication codes or approving login makes an attempt.
The victims
Panera Bread is just not the one firm ShinyHunters claims to have breached utilizing these strategies. The group has additionally named CarMax and Edmunds, and beforehand alleged breaches at Crunchbase and Betterment.

“As soon as they gained entry, the unauthorized particular person was in a position to ship a fraudulent, crypto-related message that appeared to come back from Betterment to a subset of our clients.”

ShinyHunters’ evolving ways
ShinyHunters has been energetic for a number of years and is extensively thought to be one of the crucial prolific information extortion teams at present working. In contrast to conventional ransomware gangs, the group has largely deserted using file-encrypting malware.
As a substitute, ShinyHunters focuses on quietly exfiltrating information after which demanding fee to forestall its public launch. This method reduces operational complexity, lowers the danger of detection, and may nonetheless generate substantial income.
By avoiding encryption, the group additionally sidesteps a few of the instant operational disruptions that usually drive victims to acknowledge ransomware assaults publicly. This may occasionally assist clarify why a number of firms named by ShinyHunters have remained silent to date.
