Phishing Site Encrypted With AES Designed to Steal Users’ Apple IDs

Scammers designed a phishing website and encrypted it with the Advanced Encrypted Standard (AES) in their attempts to steal unsuspecting users’ Apple IDs.

Researchers at Trend Micro came across the phishing campaign on 30 April. It all began when they received an email designed to look like it came from Apple. The email warned recipients that Apple had restricted their account access due to “unusual activity,” and it required them to update their payment information to fix the issue.

Of course, the email was a fake. Its “Update Your Payment Details” button led users to a site that looked like Apple’s sign-in page. Before going offline, the website was located at the following sanitized link: hxxp://avtive1s[.]beget[.]tech/limited/apple-couzin/apple%20couzin/Uu4gX/login.php?sslmode=true&access_token=1SGMm8LG43m4qPGE7D8Q00qCRZ2hwIVyBBkYK6FP91UzQBeYemPenfQeeTwLCrjd3EcNKRDUTxuJ8IIm.

After they attempted to sign in, the phishing website informed users that Apple had suspended their accounts due to suspicious activity. It then directed them to a sophisticated webpage designed to collect unsuspecting users’ personal and payment card information. After acquiring all of this data, the site “logged out” its victims and redirected them to Apple’s actual homepage.

This campaign wasn’t the first scheme aimed at stealing users’ Apple IDs. But what made it unique was its incorporation of code in “login.php,” “process.php” and “verified.php” to invoke JavaScript-based AES obfuscation with custom variables.

Trend Micro researcher Jindrich Karasek elaborates on what this implementation of AES encryption meant for the phishing campaign:

Network packet inspection would not identify this as malicious because the payload is hidden thanks to the encryption. The only way to spot this threat is via reputation services that identify the sender as malicious. The unique way that this phishing (Read more...)
