WeChat Pay Ransomware – Distribution Techniques

The reports about the Wechat Pay ransomware showcase that it is distributed mainly via supply-chain attack. By definition this is an attack intrusion that focuses on less-secure elements in a certain company’s infrastructure. Further information about the exact route of infection is not known at this stage.

What we know so far is that this is devised as a special attack against Chinese targets. It is very possible that the route of infection is the installation of infected software package. Such tactics take the legitimate installers of popular applications which are often installed by end users: system utilities, creativity suites and productivity applications or even games. Once they are executed by the engine the WeChat Pay ransomware will be started.

The distributed ransomware carriers have also been found to implement stolen digital certificates from Tencent Technologies. This explains the massive number of affected users which were reported at the onset of the attack campaign.

The known information about the hacker or criminal group behind the WeChat Pay ransomware attacks is a nick name “Luo”. The researchers were able to follow their QQ account number, mobile number, email IDs and their Alipay ID. The WeChat service has suspended the identified account which should stop the attacks coming in with this configuration.

WeChat Pay Ransomware – Detailed Analysis

As soon as the WeChat Pay ransomware is started it will start its built-in sequence of commands as per the current configuration. The analysis of the collected samples shows that one of the first components that are run is the password stealing one. It can scan the local hard drive, installed applications and the operating system environment for the following services: Alipay, NetEase 163 email service, Baidu Cloud Disk, Jingdong (JD.com), Taobao, Tmall , AliWangWang, and QQ.

All collected information that is hijacked will be reported to the criminals via a server connection. The local ransomware will establish a link with the hackers notifying them of the hijacked data. Other consequences of this action also includes the following:

Data Theft — The service connection can be used to hijack user data before they have been encrypted.
System Data Changes — Via this Trojan connection the criminals can manipulate the system by accessing and editing Windows Registry settings belonging both to the operating system and the third-party installed applications. This can result in the inability to launch certain functions or operations, as well as cause severe performance issues.
Additional Malware Infections — If instructed so the WeChat Pay ransomware infection can lead to the delivery of other malware.

Additionally the ransomware engine has been found to generate a report of the installed hardware components and other data that may be useful in analyzing the results of the attack campaign. The collected data may be used to generate a machine infection ID which is associated with every single compromised host.

WeChat Pay Ransomware – Encryption Process

As soon as the prior components have completed execution the actual ransomware engine will be started.

The XOR cipher has been identified to be used against the user data. The captured releases have been found to store the decryption key in the following location:

%user%\AppData\Roaming\unname_1989\dataFile\appCfg.cfg

A lockscreen instance will then be displayed to the victims notifying them that they have to pay a ransomware fee of 110 yuan in order to get access back to their data.

NOTE: A decryptor has been released for the captured early versions. You can attempt file recovery by using it.
