Right, DoS (denial of service) attack. These days most often they come as DDoS (Distributed DoS). Fortunately, most devices these days can be configured to not respond to pings. I suspect that his security blocked the ping and didn't respond. DoS via ping is less common these days, and based on the message that he said that he got, he's probably not being DoSed.

These days DoS attacks are usually done via TCP packets not ICMP.
