While Silk talks to Lenard223, Space don't do any fast actions which inside of of Len's commlink would result in an alarm. With Silk's permission of course, he supervise the communitcation to checl if Lenard223 make any trace-attampt himself.
@Silk: "I'm in, trying to encrypt some of those files."
Slowly, means closely looking at any firewall, user or countermeasure activity, Space start the encryption, taking his time. Databombs might be possible, but if he works slowly, he would most likely recongize the pattern, indicating a bomb or so. Also, the commlink to far was off-the-shelf, everybody could buy good encryption software through the matrix. Hacker tools, like data bombs, therefore you need to know the right people and places, and if Len would do so, he would already bought himself a better commlink.
