Kapela said eavesdropping could be thwarted if ISPs aggressively
filtered to allow only authorized peers to draw traffic from their
routers, and only for specific IP prefixes. But filtering is labor
intensive, and if just one ISP declines to participate, it "breaks it
for the rest of us," he said.

"Providers can prevent our attack absolutely 100 percent," Kapela
said. "They simply don't because it takes work, and to do sufficient
filtering to prevent these kinds of attacks on a global scale is cost
prohibitive."
