parsing error when creating detection rule in SecOps

Hello Commmmmunity,

I am attempting to implement the detection rule below in SecOps but keep getting an error message when I test or attempt to save the rule.

“parsing: error with token: ":" expected '=' between meta assignment key and value line: 11 column: 12-13”

rule MAL_Dropper_NetSupportRAT {

meta:

author = "Sam"

description = "Detects a dropper that delivers a decoy ChaGPT Installer and NetSupport RAT"

hash = "d86f647f3dfa6a53de7b531cb590636331f83afcea60d4b3d44de5ea3b7d33af"

malware = "NetSupport"

malware_id = "TWOU5d"

category = "MALWARE"

strings:

//dropped files

$d1 = "ChatGPT Installer.exe"

$d2 = "setup.exe"

//netsupport strings

$n1 = "NetSupport" nocase

$n2 = "install_netsupport_manager_silently"

$n3 = " [removed by moderator] "

condition:

uint16(0) == 0x5A4D and

all of ($d*) and

2 of ($n*)

}

I’m getting similar error messages for rules that have “strings:” in them. What could be wrong?
