These recent spam and hacker attacks are coming from Rumania. Curious.
Unfortunately, Rumania is climbing on the lists of sources of crackers, phishers and other cyber criminals.
In my line of business (web hosting, domain name registration and services) we see attacks like that weekly, often more frequently, and the favorite attack vectors are discussion forums, web publishing systems and contact/email scripts, most often PHP based.
There's usually nothing personal about such attacks, they're just after yet another host to either brag about or to use as the springboard for their next attacks.
There is also a strong correlation between spammers and these attacks.
