Damballa, an Internet security company has some “not so good news.” The title of their article pretty much tells it all: Kraken BotArmy—Twice as. Kraken botnet The Kraken botnet was the world’s largest botnet as of April Researchers say that Kraken infected machines in at least 50 of the Fortune. The Kraken botnet, believed by many to be the single biggest zombie network until it was dismantled last year, is staging a comeback that has.

At the recent RSA gathering Damballaan Internet security company devoted solely to researching botnet technology, is reporting some “not so good news.
For those not bottnet with Storm, up until now it had the honor of being the largest and most notorious botnet to date. Experts consider the Storm botnet to be powerful enough to knock entire countries off the Internet. The Wikipedia entry ” Storm botnet ” gives an accurate accounting of how the Storm Worm — a trojan horse that spreads through e-mail — is used to recruit infected computers zombies into the Storm botnet.
Estimates have the number of zombies to be aroundThe Wiki entry also does a nice job of explaining what a botnet is and how it can be such a threat. Some very sophisticated coding goes into botnet programs.
For example, servers controlling the botnet automatically change the software code at pre-determined times to avoid detection by antivirus applications. On top of that, all botnet management traffic is encrypted and uses peer-to-peer control techniques, which make monitoring and disabling the botnet very difficult.
Both Storm and Kraken rely on social engineering to propagate.

Damballa believes that the preferred attack venue is to have the malware appear as an image file. When a user attempts to view the file, it’s all over. For those wondering if they may be infected, Damballa lists compromised public IP addresses on its Web site that it updates regularly. If perchance, you find a public IP address on the list that you are concerned about, Damballa has remediation instructions that explain how to identify the process gotnet remove the malware.
Using this approach eliminates the problem of having a portion of the botnet go down if one of the peers is taken off-line. It appears that infected computers don’t just belong to what researchers like to call the non-tech-savvy computer users.
At last count, 50 Fortune companies have compromised computers. Paul Royal, principal researcher at Damballa commented that Damballa is trying to figure out how the bot infestation is getting past the perimeter defenses of some of the best-protected networks in the world:.
For now, it appears that the Kraken botnet is just delivering massive amounts of spam. Damballa claims to have seen some infected machines sending overspam messages per day.
I do not even want to think about what a half a million infected machines sendingmessages per day would do to most anti-spam services.
Inside the Raspberry Pi: How self-driving tractors, AI, and precision agriculture will save us from the impending food crisis. How IoT, robotics, and AI are tackling one of the biggest problems of the century.
