Posted by Alex Ivanoff On May - 13 - 2009

Experts say, 20-minute long broadband connection to Internet is enough for a malefactor to break into an unprotected PC. Just imagine what can happen if a corporate network is connected to the Internet without proper protection. Infected workstations and stolen intellectual property are the most predictable consequences but things can go even worse.

Installing a firewall may help to protect your network, however this will work only if the firewall is properly configured. Let’s see what are the main principles of firewall configuration.

Security Threats in 2008. Current trends.

Posted by Alex Ivanoff On February - 11 - 2009

Kaspersky Laboratories published an annual report where most actual security threats are reviewed and analyzed. Experts say, the most current trend is the development of a complex global virus ‘eco-system’. Almost 90% of malware were produced for the purpose of subsequent selling. Chinese hackers and virus writers made the major part of the malware, however the most sophysticated examples of spyware and viruses were made in Russia.

Last year “Kaspersky Lab” reported that 24 million users had been attacked from Internet. The experts warn of increasing number of social network attacks and huge growth of the number of malware used to steal credentials for online games. Another urgent problem that grows in a scary fast pace is spread of rootkits. Rootkits are special tools used to hide malicious software on a user’s system by takeover of control over system functions or data structures. Botnets become more and more widespread and therefore represent one more critical threat in the modern IT world.

At the same time electronic junk mail distribution has not grown significantly. Avarage part of junk in email traffic has reached 82.1% — this is 2.1% more than in 2007. The world’s leader of spam discribution is Russian Federation (22%).

The experts predict that the situation will get much worse in 2009. What can be done to avoid distressing consequences? Do as much as possible to protect your PC, your mobile devices, your network environment and your private data. Update your antivirus daily, use a firewall, be careful when paying at internet shops and subscribe for a website monitoring account in order to know first if your blog has been defaced or infected by a malware.

Spammers Grow Up

Posted by Alex Ivanoff On November - 11 - 2008

Spammers have evolved to perpetrate some pretty complicated schemes to get their wares (and warez) to large audiences. Recently they’ve shown sophistication beyond simple mailings by breaking CAPTCHA codes, enlisting decoy social networking sites and blogs, and even some search engine optimization.

It’s a tangled web, the intricate knitting started with exploiting CAPTCHA (Completely Automated Public Turing Test to tell Computers and Humans Apart-in case you never knew) vulnerabilities to set up email accounts, which are required to set up blogs and/or profiles on social networks with enough traffic and clout to pop up in the search results.
