I think the Damage is a lot higher. Dataspike Damage is Attack rating/2 round Up.
Attack rating = Attack+Sleaze.
So its not your Attack Attribute, but your Attack rating ( which partly consists og your Attack Attribute) that determines your Damage value.
So its between 4 and 9.
Wow, you are right about RAW. That doesn't quite jive with page 174, however:
Attack represents the offensive power of the device in cybercombat and how much damage it can do when attacking.
But you're 100% correct, the rule for Data Spike does specify "Attack Rating/2". That... is wild.
EDIT:
@Banshee Can you comment on this? There are no examples for Data Spike, but it seems unlikely that the intent was for Data Spike DV to be (Attack+Sleaze)/2 as opposed to (Attack)/2, but the way this is worded straight up says "Attack Rating", not "Attack attribute" or "Attack Rank".
This has pretty significant consequences. Assuming the default A/S values for the available cyberdecks, your BASE Matrix DV with Data Spike is:
Erika MCD-6: A/S 4/3, Attack Rating 7, base DV 4
Spinrad Falcon: A/S 5/4, Attack Rating 9, base DV 5
MCT 360: A/S 6/5, Attack Rating 11, base DV 6
Renraku Kitsune: A/S 7/6, Attack Rating 13, base DV 7
Shiawase Cyber-6: A/S 8/7, Attack Rating 15, base DV 8
Fairlight Excalibur: A/S 9/8, Attack Rating 17, base DV 9
In other words, the higher end decks are likely to be able to take out most generic devices (Condition Monitor 8 + (Device Rating / 2) = range of 9-13) in a single Data Spike Attack. Add Fork to the mix and you're bricking two different devices with a single attack action.
This seems wildly disproportionate to physical combat, where DV values (other than explosives, rockets/missiles, and grenades) range from 2P to 6P.
Regarding the First part of the quoted text. Ejere do I find the rules for PAN granting firewall and DP processing ratings to my slaver gear? I feel like Ive made a critical glitch on my search check :/
Page 174:
Most people access the Matrix through a device. Nowadays, everyone has a commlink, a pocket-sized smart device that interfaces with the Matrix at large. Some are integrated into glasses, or even fully into cybernetic augmentation, while others still have the familiar handheld screen look. They are used for rudimentary access, most commonly for commcalls and searches, as well as basic Matrix Firewall defense for devices attached to the user’s PAN.
