Now hereâ€™s a welcome change of pace as far as Internet security news goes â€“ spam went down in 2012!
According to Kaspersky Labâ€™s Spam Report 2012, percentage of spam last year was 8.2% less compared to 2011.
But sadly, this isnâ€™t all good news. In fact, this is the only positive bit in Kaspersky Labâ€™s latest press release.
In the last quarter of 2012, the number of malicious attachments aimed at steeling user account information (i.e. usernames and passwords) increased significantly and the number of spam originating from the US and China grew substantially. The Philippines is still part of the list of top 20 countries where spam is coming from, but thankfully, weâ€™re in the bottom 10.
So yeah, it’s one point for the good guys, but still a long way to go before the net is a once again a safer place for you and me.
Full deets in the press release below:
SPAM LEVELS DECLINE IN 2012, KASPERSKY LAB REPORT SAYS
Same year also saw the spread of malicious programs that steal usernames and logins
Kaspersky Lab, a leading secure content and threat management solutions developer, recently released a report saying the decrease in spam in 2012 was caused by a heightened use of anti-spam protection among Internet users worldwide.
As of the end of the year, the percentage of spam ended at 72.1% – 8.2% less than in 2011, according to the Spam Report 2012 by Kaspersky Lab.
2012 also saw a comparably huge decline in spam volumes than in 2010, reporting with 82.2%, and in 2011, which reported 80.3% spam volumes. The shuttering of several botnet command centers and pharmaceutical affiliate programs in 2012 also contributed to the spam volume decline.
Apart from the use of anti-spam applications, another reason for the decline of spam is the use of mandatory DKIM (domain key identified mail) signature policies by email providers.
DKIMs are digital signatures that verify the domain from which emails are sent.
Darya Gudkova, Kaspersky Lab Head of Content Analysis & Research said that the percentage of spam decreased over the course of the year, and during the final three months of 2012 the figure remained below 70%.
But even with the decline of spam volumes in 2012, there were some major changes in terms of the source country of spam.
China was suddenly thrust into the top of the list of spam sources for 2012, contributing 19.5% of all unsolicited email. This is unprecedented as China was not even in the top 20 spam sources in 2011, which was topped by India then.
The entry of China in the top list already increases Asiaâ€™s ranking as the primary regional source of spam, rising 11.2 percentage points for 2012, finally contributing 50% of all spam. North America took second place with 15.8% last year.
Meanwhile, the amount of spam originating in Latin America fell by 8 percentage points and closed at 11.8%. Europe also dropped down in ranks last 2012, the total amount of spam originating in Western and Eastern Europe combined came to 15.1%, which is about half the amount in 2011.
Among the top 20 countries that are sources of spam for 2012 is the Philippines contributing 1.1%. It is ranked among the last 10 countries contributing less than two percent of the overall spam.
Kaspersky Lab also reported that despite the decrease in overall percentage of spam in mail traffic, the proportion of emails with malicious attachments fell only slightly to 3.4%.
The company said this is still a significantly huge percentage since it only reflects emails with malicious attachments and not spam messages containing links to malicious websites.
In 2012, Trojan-Spy.HTML.Fraud.gen was the most common malicious attachment. The fourth quarter saw a change and the most prevalent malicious attachments were Trojan-Spy.Win32.Zbot.fsfe and Trojan-PSW.Win32.Tepfer.cfwf.
These three malware were designed to steal user account information such as usernames and passwords. Fraud.gen and Zbot specifically targeted passwords from financial and payment systems, while Tepfer stole other types of passwords.
The volume of spam from the US and China grew substantially in 2012 and even if anti-spam laws were passed and botnets were shut down, spammers were still taking advantage of powerful computing resources in both countries. These computing resources were then used to build new botnets in those countries.
Kaspersky Lab also reiterated in its report that the volume of malicious emails remained high throughout the year. Malicious users are copying even broader range of legitimate notifications. 2012 also saw the spread of malicious programs that steal usernames and logins, focusing primarily on account information for financial services. Nevertheless, creators of these malicious programs also want passwords from social networks, email accounts, and other services.
In this situation, Kaspersky Lab reminded Internet users to keep safe: when you receive an email, make sure that it was actually sent from the resource that it claims to be. Never click on links in suspicious emails, and remember, it is critically important to update your software regularly.
“This drop is the result of a gradual departure of advertisers from spam to other, more convenient and legal means of promoting goods and services. However, that doesnâ€™t mean spam is headed the way of the dodo anytime soon: malicious spam, fraud, and advertising of illegal goods cannot simply or easily migrate to legal platforms, due to their own inherently criminal nature. We expect that the decline in spam volumes in 2013 will be negligible at best,” Gudkova said.
