<div style="clear: both;">Notem que em 1 segundo o "invasor" tentou várias vezes se registrar no sip 1013 (através do método BruteForce) pelo meu link do speedy. O IP do "invasor" é 174.129.173.249.</div>
<div style="clear: both;"> </div>
<div style="clear: both;">Isso seria uma tentativa de invasão? </div>
<div style="clear: both;"> </div>
<div style="clear: both;">Se sim, como ele conseguiu acesso aos meus ramais SIP?</div>
<div style="clear: both;">O que preciso fazer para tirar esse cara da rede?</div>
<div style="clear: both;"> </div>
<div style="clear: both;">Em uma pesquisa rápida descobri que esse IP é de Washington.</div>

<div style="clear: both;"> </div>
<div style="clear: both;">Estou alarmado a toa ou é realmente uma tentativa de invasão?</div>
