Contains the collections framework, legacy collection classes, event model, date and time facilities, internationalization, and miscellaneous utility classes (a string tokenizer, a random-number generator, and a bit array). It contains a GSM MAP processUnstructuredSS-Request MAP operation with a USSD String (GSM 7 bit encoded). The above Wireshark filter should show you Hancitor’s IP address check followed by HTTP POST requests for Hancitor C2 traffic, as shown below in Figure 16. For HTTP, you can use a capture filter of: tcp port 80. or a display filter of: tcp.port == 80. or: http. A field may be checked for matches against a set of values simply with the membership operator. It contains a GSM MAP processUnstructuredSS-Request MAP operation with a USSD String (GSM 7 bit encoded). Usually an IP frame has only two addresses (source and destination), but in case of ICMP errors or tunneling, a single packet might contain even more addresses. And this is the last line.
