Kaspersky Lab has revealed that online scammers are increasingly targeting social network accounts and in November, spammers focused on Flickr, Twitter and LinkedIn while phishers showed a preference for Habbo.
This November, Flickr users received emails sent from Flickr accounts that contained links to a pharmaceutical site, Twitter fell victim to a similar spammer trick, with invitations to join the social networking site that looked like they were sent on behalf of Twitter users. The invitations contained an adult message and a link that redirected users to an adult site.
In November LinkedIn was also targeted. An unusual mass mailing message, which imitated an official notification from LinkedIn, was sent to many LinkedIn users. The message warned the recipient that a recent transaction made via an e-pay system had been cancelled.
According to Kaspersky Lab, the cybercriminals had got their wires crossed and sent a fake notification from the Nacha payment system that looked like it came from LinkedIn.
Habbo rose to second place in terms of social networks being compromised by phishing attacks. In October the site had dropped out of the phishing Top 10 altogether, but in November, the share of attacks on this social networking site increased ten times.
The number of attacks targeting Facebook also grew slightly, placing it in 4th position.
Cyber-criminals are also distributing mass mailings enticing users to leave their financial and personal data on a phishing site. Kaspersky Lab registered several mass mailings of fake notifications from internet stores.
The names of specific internet stores were not used, but the recipients of the mail were invited to look through a bill or click a link to check an order reference.The link led to malicious code.
In addition to the main winter holidays mass mailings also targeted Eid al-Adha. The emails exploiting Eid al-Adha were mostly in Turkish and advertised religious tourism.
The top two countries with the highest rates of email antivirus detection remained unchanged: Russia stayed out in front, 6 percentage points ahead of the US. Both countries showed an increase – 3.39 and 2.77 percentage points respectively – compared with October.
