Symantec recently upgraded their scanner on VirusTotal to include their new reputation-based security engine. That has caused a spike in their detection rates, in particular Suspicious.Insight detections, and so I thought I’d take a few minutes to explain some of the background and what is going on. So what exactly is a Suspicious.Insight detection? These detections are derived from Symantec’s new reputation-based security technology. They highlight files that have not yet developed a strong reputation (either good or bad) amongst Symantec’s community of users. their goal is to keep their users’ machines safe, and part of achieving that goal means helping their users make informed choices about the files they allow on to their systems. Suspicious.Insight detections help shine a spotlight on files that have not yet developed a full reputation. ...

First, make a note: after Adobe updates, restart your machine immediately to remove the Adobe Download Manger – it can be a vector for malcode. Now, back to our story. Aviv Raff has discovered a vulnerability with Adobe’s web site in combination with its Download Manager, an ActiveX script that is used to download updates for Reader and Flash. After a Reader or Flash update the download manager remains running on a user’s machine until it is rebooted. Malicious operators could exploit it to download their code of choice. ...

Representatives of computer companies and governments meeting at the EastWest Institute security meeting in Brussels said that an industry culture of obscure jargon is preventing the world’s two billion Internet users from putting security measures in place to protect themselves. The group met to figure out how to protect computer users from massive abuse, fraud, online theft, vandalism and espionage. The New York Times story carried the following quotes from those at the meeting: ...

In the month of January, we reported a drop in .cn spam. This was due to changes in the domain registration process introduced by CNNIC. In the first week of February, the .cn spam volume fell further and fluctuated between 0 and 4 percent of total URL spam. Another interesting trend was observed during this period. On January 21 the volume of spam containing the .ru top-level domain (TLD) spiked up to 9 percent, and rose further up to close to 40 percent on February 8. Upon closer analysis, it was observed that the .cn domains used in the health spam attacks had been replaced with .ru domains. ...

Some of the tools that help sellers in auctions are: image hosting to display galleries of their products, listing of best bidders in a single template, automatic inventory systems to notify sellers during low stocks, etc. With the help of these tools, online auctions are easier and time saving. ...

I saw something quite funny when checking out the spam feeds the other day. An attachment kept appearing, once in a while, with a name of Christmas Card.zip. It was making sporadic appearances in the feeds (and the number of spam email messages was quite low), but there were a couple of these odd messages at equally odd hours of the day: The email message itself was a run-of-the-mill electronic greeting card with an HTML body containing a nice Flash animation—the Flash animation actually comes from a legitimate source (123greetings.com). The email body contains a message asking the user to open the attachment to see who sent the email. Of course, opening the attachment yields a malicious file. The name of the file inside is _**Christmas Card.htm[MANY SPACES].exe **_and it is already detected by Symantec as W32.Ackantta.G@mm. ...

In the last two days our lab has detected a flood of email messages that seem to have been sent by the Facebook team urging users to submit a new account agreement.

The message is like the following: Users are required to submit a new account agreement before a certain date. If not, their Facebook account will be restricted.

It’s Fat Tuesday — time for an Adobe Update. Adobe plans to release a security update for Adobe Reader and Acrobat later today. Read Security Advisory APSB10-07 for additional details.

While most sane people around the world are enjoying a romantic Valentine’s Day today, we at SophosLabs remain vigilant on the front line of the war against malware. This year, Valentines Day coincides with the Chinese New Year as well as the start of the Winter Olympics in Vancouver, and many malware attacks have centred around SEO poisoning of these and other topical search terms. The Chinese New Year of the Tiger is proving a popular target, especially as this ties in with any Tiger Woods related searches: ...
