During your career as a high ranked officer of the Liberty Navy you surely must have been briefed on Outcasts and their links with the Liberty underground, including The Lane Hackers. I am also quite certain that you must have been informed at least briefly about the elite 101st Outcast special operations squadron called "Ghosts of Razgriz". They have came to prominence shortly after "Reapers of Sirius" - another para-military entity - were exiled from Malta almost a decade ago. Ghosts were so successful with domestic operations that their administration instantly took over the Council of Dons and basically ruled over Malta for years to come.
Around four years ago, shortly after administration of the Ghosts has been taken over by the Casta family, 101st's influence over Malta started to collapse with the rise of the rival Contari clan. Escalating tensions between these two fueled by frequent shows of utter arrogance eventually led to an outbreak of a civil war. The same unhealthy arrogance and lack of diplomatic skills showed by both Estefania Casta and her sister Gabriella alienated most of 101st's allies. Despite initial achievements on the battlefield, the war left Ghosts weakened and giving up most of their political influence to the Contari Lance and later other great families as well.
The Ghosts' influence and strength diminished over time with the culmination being the banishment of entire remaining squadron and Estefania Casta herself from Malta by the National Council. Besides freezing or confiscation of their assets, a hefty bounty has been established by Fedeltà, current ruling body of Malta, to hunt down Estefania and any 101st still alive. According to our intelligence Casta sisters, besides their most loyal servants and security detachment, are alone in their endevours. Being cut out from funding, supplies and reinforcements they do not posses any strategically viable operational capabilities. To honor almost decade old treaties and years of successful cooperation in the past, the Professorship refused to hunt down Casta sisters and instead decided to ignore them as long as their actions do not directly harm Lane Hacker' interests within Liberty.
As for Gabriella Casta particularly, according to our intelligence, she is a very talented operative with a versatile set of skills. Unfortunately, blood of her family runs deep in her and thus she suffers greatly from the same vices as her sister, namely extreme arrogance, toxic character and strong delusions concerning her actual influence and power. One of my assassins was present in Texas during the incident you spoke of. As I was told she desperately wanted some information on your battlegroup. Looks like she decided to seek information at the source. During the encounter she was using a modified transponder [GoR]. We speculate that she abandoned original transponder [101st] to confuse bounty hunters on her tail, but we cannot confirm it at this point.
