1H 2009: Malware Threat Grows Ever LargerMalware threats have undergone many, many stages of evolution over the years. First it was DOS viruses, then macro viruses, then mass-mailers, then botnets, then Web threats… the only constants seem to be that these are growing both in number and in danger. TrendLabs has seen this continued growth of malware. The effects on users is clear: in the first six months of 2008, the Trend Micro World Virus Tracking Center (WTC) recorded that 253.4 million systems were infected with malware. The comparable volume for 2009 is almost double at 491.2 million. While not a welcome development, this wasn’t unexpected either. The official 2009 Trend Micro forecast pointed out that malware threats had been growing for years, and 2009 was going to see more of the same. It’s not just limited to Trend Micro, either. AV-Test.org has released their findings for the first half of the year recently, and the charts present a rather worrying picture:
With more than a million new samples being seen every month, it’s likely that the overall number of unique samples will grow beyond 30 million. That should clearly illustrate the scale of the malware threat. As the threat continues to grow, so will the system resources needed to protect users from it. How else can users cope up with this threat growth? In my years of experience managing malware signatures, I believe that the only way to go is in the cloud because that’s how we can effectively take the conventional anti-malware protection approach and place malware definitions in the cloud to reduce the impact of repeated, increasing pattern delivery on a customer's network. Likewise, other benefits made evident by this move are:
As a result, users are protected from threats more quickly. Post from: TrendLabs | Malware Blog - by Trend Micro
Brazil: Spam Changing A HOSTS File?We have recently detected a new spam attack that attempts to grab the bank data of Brazilian users. The mechanics of this attack are simple. Users receive this spam email: The mail claims that the user has received an e-card, and contains a link to “read” the said card. Click on the related link, a file is downloaded and executed: Apparently nothing happens, just an Internet Explorer is opened showing a related web card from this initial phishing. In the background, however, the HOSTS file is changed, and set to redirect certain Brazilian baking Web sites to a malicious web site. All information posted in any of the said pages will then be grabbed by the attacker. This spam email is now blocked by the Smart Protection Network. In addition, the malicious file involved is now detected as TSPY_BANCOS.JCM, and the malicious Web site is also blocked. Post from: TrendLabs | Malware Blog - by Trend Micro More Recent Articles |
