Confidence: 100%

Signatures

Antivirus / Scanner detection for submitted sample
Found malware configuration
Yara detected Dridex unpacked file
Multi AV Scanner detection for submitted file
Detected unpacking (changes PE section rights)
Detected unpacking (overwrites its own PE header)
Detected Dridex e-Banking trojan
Yara detected CryptOne packer
C2 URLs / IPs found in malware configuration
Machine Learning detection for sample
Uses 32bit PE files
Found a high number of Window / User specific system calls (may be a loop to detect user behavior)
Sample file is different than original file name gathered from version info
PE file contains strange resources
May sleep (evasive loops) to hinder dynamic analysis
Found evasive API chain checking for process token information
Uses code obfuscation techniques (call, push, ret)
Detected TCP or UDP traffic on non-standard ports
PE file contains sections with non-standard names
Queries the installation date of Windows
Internet Provider seen in connection with other malware
