Analyst notes

ChinaSMSStealer. SMS-intercepting stealer exfiltrating over email rather than a network C2: the SMTP account and password sit as const-strings in the i()/j() accessors of Lcom/phone/stop/db/a;. Detected by a four-part manifest fingerprint (INTERNET, activity.MainActivity, receiver.SMSReceiver, service.SecondService). Indicators: fvsvsvsvsv@vip.163.com:12233.
