New Survey Lists Top Eleven Botnets

Joe Stewart, director of malware research at SecureWorks Inc., presented a survey ranking the top 11botnets that send an estimated 100 billion spam messages a day from over a million hacked systems.

Botnet # of bots Spam capability
1 Srizbi 315,000 60Billion/day
2 Bobax 185,000 9Billion/day
3 Rustock 150,000 30Billion/day
4 Cutwail 125,000 16Billion/day
5 Storm 85,000 3Billion/day
6 Grum 50,000 2Billion/day
7 Onewordsub 40,000 Unknown
8 Ozdok 35,000 10Billion/day
9 Nucrypt 20,000 5Billion/day
10 Wopla 20,000 600Million/day
11 Spamthru 12,000 350Million/day

Stewart’s research also helps categorize bots and reduce confusion regarding different botnets under the same name, proving through SMTP ‘fingerprints’ that certain previously discovered bots like “Kracken” are
really just variations of existing bots, in the case of Kracken, Bobax.

Kaspersky AntiVirus 7.0: Protection from Viruses and Other Internet Threats

May 13th, 2008 No Comments »

The number of Internet security threats is constantly increasing, and to protect your data and the integrity of your system you need an anti-virus solution, such as Kaspersky AntiVirus 7.0. Due to holes in security created by a rapidly evolving Internet, the threat posed by cyber criminals and hackers is becoming increasingly severe. Kaspersky’s sophisticated software package offers many features that are essential to reducing your threat of virus exposure and infection.

Viruses are not the only criminal activity on the Internet today, and threats such as spyware, phishers, and hackers pose tremendous risk to your network security. A growing problem, identity theft has likely already affected you or someone else that you know. If your system is hacked, or your laptop is lost or stolen, your sensitive personal and financial information can become compromised. Kaspersky AntiVirus 7.0 scans web files and email for malware and other threats, allowing you to browse the Internet without worry.

As new viruses and other threats continue to surface, the technology used to create them is becoming more complex and difficult to detect. Virus programmers are always looking for ways to layer on encryption to conceal their code deep within your system where many anti-virus programs cannot find it. Anti-virus programming must constantly evolve to keep up with these always-changing threats.

Many anti-virus programs offer only periodic updates, and your system can be attacked before your software even recognizes the threat. Kaspersky AntiVirus 7.0 provides automatic hourly updates, and is able to respond to malware threats within two hours of detection. The unparalleled number of updates each month prevents new viruses from entering your system undetected.

Malware moves quickly, and some viruses are capable of destroying files within seconds. Therefore, it is vital to use anti-virus software that is able to minimize attacks before they happen. Kaspersky AntiVirus 7.0 utilizes intelligent proactive heuristics, which allows for the automatic isolation of files without a match to those contained in the signature database. This way, code is checked in a safe place, reducing the risk of harm to your computer. To prevent possible viral infection, Kaspersky monitors your system with real-time behavior analysis. The anti-virus software will alert you to any potential problems immediately, roll back malicious changes to your system, and restore files that have been encrypted with ransomware.

Ranked first in both independent tests and reviews, Kaspersky AntiVirus 7.0 is the leading anti-virus software.It finds and neutralizes more threats more quickly to keep your computer and private information safe. Kaspersky even varies its scans based on the user’s activity for a customized approach. Based on its variety of sophisticated features and impressive rate of updates, it is easy to understand why Kaspersky AntiVirus 7.0 is the anti-virus software preferred by so many people.

Spam is Back in Full Force

May 1st, 2008 No Comments »

Symantec’s Monthly State of Spam report for March showed an increase in bounced messages that found spammers forging sent email addresses and using them in the “From” header of their own Spam messages.

Reminiscent of Backscatter, spammers are taking advantage of mail transfer agents configured to send back a list of failed email recipient addresses, an explanation of the cause of failure, and a copy of the original email. This opens a window for Spam attacks, as anti-spam filters do not block most “failed email” replies. Since spammers forge the sender’s address, this mail is going to be received by people who have nothing to do with the Spam.

Corporate networks will feel the greatest burden of the increased attacks. Using increased bandwidth and an increase of unwanted Spam messages in users’ inboxes will result in lost productivity. Networks are encouraged to configure mail transfer agents to not send back a copy of the original failed messages and require signatures for outgoing emails.
