A new online banking scam is making fraudulent purchases, and hiding the evidence by removing those fake expenditures from your online statements.
In the past, hackers and others with too much time on their hands would hijack your banking information, and then make some ridiculous purchase or outrageous money transfer.
Ultimately, you would see the random purchase when you log in to your online banking website, before calling them up to see what the heck happened (and attempt to get your money back).
Well, malware (the sneaky software which causes this nonsense) is now hiding the evidence.
