To find a vertical asymptote, you are trying to find values of x that produce 0 in the denominator but not in the numerator. If 0/0 occurs, that means you have a "hole" in the graph. A vertical asymptote is a place in the graph of infinite discontinuity, where the graph spikes off to positive or negative infinity. To find the vertical asymptote, set the denominator equal to zero and solve for x. Check that the values also do not give a zero in the nominator. If the values work, you have found...

It is said that the best way to avoid detection when hacking is to leave no trace, and often that means not touching the filesystem at all. But realistically, in most cases, it's impossible not to interact with the filesystem in one way or another. The next best thing to do to throw off any investigators is to change the file attributes to hide activity. We can do this with Metasploit's Timestomp.
