(WEB HOST INDUSTRY REVIEW) — The past few months has seen a rise in large distributed denial of service attacks which threaten to send entire countries offline, raising concerns among Internet security experts in the Internet infrastructure that help contribute to these attacks, according to a report by The Washington Post.
These DDoS attacks use botnets to send large amounts of spam to websites to the point where it cannot handle incoming traffic from its regular visitors.
In the past six months, DDoS monitoring firm Arbor Networks (www.arbornetworks.com) says it has witnessed a rise in the number, sophistication and size of these attacks, while perpetrators seem to be targeting larger ISPs.
Earlier this month, domain registrar Register.com was hit by a major DDoS attack that caused causing intermittent outages for about 48 hours.
The Post article also cites recent DDoS attacks against dedicated managed hosting provider The Planet, which it says was hit by a “massive” DDoS attack on April 6 and 7, as well as Brazillian ISP Telefonica, which lasted for several days.
Though DDoS attacks are typically seen as the work of cyber criminals who are seeking some kind of financial compensation in exchange for retreating these attacks.
All three of the aforementioned companies were performed in precise intervals over a period of days, according to The Post.
Experts say that the nature of these attacks suggest that the hackers were just showing off their malicious capabilities to attract media coverage in an effort to draw interest from criminals that would hire them for their services.
The domain name system contains many DDoS assault attack weaknesses, which is a key component of the Internet.
Since the global DNS system does not yet have a widely deployed system in place to confirm the location of an individual requesting a site’s location, it makes it harder to block DDoS attackers that lie about their location, according to The Post.
Additionally, there has also been a rise in the number of botnets used to attack networks has largely increased because of globally-spreadl viruses like the Conficker worm.
These attacks are significantly easier to defend against as inffective individuals can work with their ISP to find and drop traffic from the Internet source.
ISPs can also improve their defense against DDoS attacks by adopting long-established Internet best practices.
