====================================================
Internet Hacking is now a way of life. It is in
the news everyday and seems to get worse. Many dismiss the thought that
it is not beyond malicious hacking of people or institutions. However, it has now become far worse with fake news, influencing elections and misinformation.
What;s next is far more chilling, the potential
to ruin economies, cause massive damage and generating events as
crippling as any war.

Nation States May Be Plotting Internet Takedown, Warns
Cybersec Pro

Unknown attackers have been testing
the defenses of companies that run critical parts of the Internet, possibly to
figure out how to take them down,
cybersecurity expert Bruce Schneier warned Tuesday.
Large nation states -- perhaps China
or Russia -- are the likely culprits, he suggested.
"Nation state actors are going
to probe to find weaknesses in all of our technologies," said Travis
Smith, senior security research engineer at Tripwire.
They "want to know what can be
done not only in the event of a cyberwar but a kinetic war as well," he
told TechNewsWorld.
The Growing DDoS Threat
The easiest way to take a network
off the Internet is with a distributed denial of service attack, Schneier said,
and some of the targeted companies recently have been hit with DDoS attacks
that are significantly larger, longer lasting, and more sophisticated than
before.
The attacks typically ramp up to a
particular level then stop. They resume at that higher level and then continue
ramping up, as if the attackers are looking for the network's exact point of
failure, Schneier speculated. The attacks use multiple vectors, forcing targets
to deploy all of their defenses, thus disclosing their capabilities.
DDoS and other attacks hit record heights in
the second quarter of this year, Akamai reported. DDoS attacks rose 23 percent
over the number recorded in Q4, 2015, and Web application attacks increased 26
percent.
Targets suffered a greater number of
repeat DDoS attacks -- 29 on average. Multivectored attacks increased, as did
mega-attacks of more than 100 Gbps using simple attack vectors.
Possible or Not?
State actors "are probably
looking at a number of different ways to disable parts or all of the
Internet," commented Paul Mockapetris, coinventor of the domain name
system, currently chief scientist at ThreatStop.
DDoS is one of the ways to do that,
and "I would imagine state actors would attack routing systems as
well," he told TechNewsWorld.
The attacks would be most effective
against shared commons -- the public resources on the Web -- but "people
could go back to the system of partitioning the Internet," Mockapetris
suggested. "Those who have their own protected network will continue to
have Internet access."
A takedown of the entire Internet is
not going to happen, contended Martin McKeay, security advocate at Akamai,
because "it's a whole bunch of networks, and you're not going to take it
down unless you take down all the circuits. You can take down a company, an
organization, or part of a government -- but you can't really take down the
Internet as a whole."
Communications links are too
widespread for a global attack to succeed, he told TechNewsWorld. There are
"a couple dozen terabit circuits from San Francisco alone, to Hong Kong
and Tokyo and other places."
The largest network layer attacks
seen so far, approaching 500 Gbps, "are an order of magnitude smaller than
the bandwidth capacity the largest transit providers and ISPs manage,"
noted Tim Mathews, vice president of the Incapsula product line at Imperva.
"With proper DDoS protections
in place, most attacks would be stopped in their tracks," he told
TechNewsWorld.
Worst-Case Scenarios
The loss of utilities and emergency
services resulting from an Internet takedown could "promote the
establishment of militia groups" and, possibly, a breakdown of society,
warned Michael Patterson, CEO of Plixer. "Imagine
your neighbors excluding you from protection because you have no resources to
share."
The responsibility to safeguard the
Internet from attacks "has fallen largely on service providers," he
told TechNewsWorld.
In the short run, banks and other
businesses could sustain considerable economic losses if the Internet went down
and they lost ephemeral transactional data, Akamai's McKeay suggested, but
"long-term outages aren't a problem."
