Digital DNA sequence

An electronic device for generating a sequence that classifies a data object to determine whether the data object is a malicious object, the device comprising:

• a memory;
• and
• a sequencing engine, wherein the sequencing engine is configured to be executed by one or more processors, the sequencing engine including instructions for:
• applying to the data object a plurality of rules, each rule of the plurality of rules associated with a respective weight value and with a respective trait, to select expressed traits, wherein an expressed trait corresponds to a rule that matches the data object;
• generating a sequence comprising each of the weight values associated with the expressed traits, wherein each of the weight values corresponds to a likelihood of whether the data object belongs to a respective class of data objects;
• calculating a sequence weight based on the weight values associated with each of the expressed traits, wherein calculating a sequence weight comprises reducing a weight value of an expressed trait for a subsequent expression of the same trait, including:
• determining whether a first rule of the plurality of rules matches the data object for a first time;
• in accordance with determining that the first rule of the plurality of rules matches the data object for the first time, utilizing a first weight value in calculating the sequence weight;
• determining whether the first rule of the plurality of rules matches the data object for a second time that is subsequent to the first time;
• and
• in accordance with determining that the first rule of the plurality of rules matches the data object for the second time that is subsequent to the first time, utilizing a second weight value that is less than the first weight value in calculating the sequence weight;
• and
• storing the generated sequence in a selected target memory.

A non-transitory computer-readable storage medium storing instructions for execution by an electronic device for generating a sequence that classifies a data object to determine whether the data object is a malicious object, the instructions comprising instructions for:

• applying to the data object a plurality of rules, each rule of the plurality of rules associated with a respective weight value and with a respective trait, to select expressed traits, wherein an expressed trait corresponds to a rule that matches the data object;
• generating a sequence comprising each of the weight values associated with the expressed traits, wherein each of the weight values corresponds to a likelihood of whether the data object belongs to a respective class of data objects;
• calculating a sequence weight based on the weight values associated with each of the expressed traits, wherein calculating a sequence weight comprises reducing a weight value of an expressed trait for a subsequent expression of the same trait, including:
• determining whether a first rule of the plurality of rules matches the data object for a first time;
• in accordance with determining that the first rule of the plurality of rules matches the data object for the first time, utilizing a first weight value in calculating the sequence weight;
• determining whether the first rule of the plurality of rules matches the data object for a second time that is subsequent to the first time;
• and
• in accordance with determining that the first rule of the plurality of rules matches the data object for the second time that is subsequent to the first time, utilizing a second weight value that is less than the first weight value in calculating the sequence weight;
• and
• storing the generated sequence in a selected target memory of the electronic device.
