Scammers Offering Tax Refunds

Published: February 21, 2010 Reading time: 2 min

Fraudsters never seem to rest. They have now turned their attention towards phishing using the Indian Income Tax Department’s name and branding. It is the season of tax returns in India and it is well known that people will file their income tax returns for the end of the fiscal year in India. Hence, phishers have chosen the right time to phish the market since most users will not be aware of these attacks. ...

Apple iPhone Warranty Scam

Published: February 21, 2010 Reading time: 2 min

Symantec has recently observed phishing scams targeting Apple iPhones in order to gain serial numbers, IMEI, model, and capacity, etc. What is an IMEI? An IMEI (international mobile equipment identity) is a 15-digit unique number used by GSM networks to identify valid devices. Every GSM, WCDMA, or iDEN mobile phone (and even the odd satellite phone) has an IMEI. It can be found under the battery of the device or by typing *#06# on the mobile. If your phone or device is lost or stolen you can report it to your service provider, providing the IMEI number. The service provider can then blacklist the IMEI number, rendering the device unusable in that country. ...

Exploit for zero-day vuln in Firefox is for sale

Published: February 21, 2010 Reading time: 1 min

Evgeny Legerov, founder of Intevydis in Moscow, has created an exploit that hits a previously unknown heap-corruption vulnerability in the Firefox browser. The code isn’t readily available though, since he’s put it in a module to the automated exploitation system he sells (reportedly at a considerable price.) Legerov has not provided information on the vulnerability to Mozilla. The Intevydis site says: “Exploitation frameworks are not new on the market, but only we may offer you hundreds of CANVAS modules for unpatched and unknown vulnerabilities in highly popular software products.” ...

Symantec Reputation-based Security: Suspicious.Insight detections on VirusTotal

Published: February 21, 2010 Reading time: 4 min

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. ...

The .ru Substitutions for .cn Domains

Published: February 21, 2010 Reading time: 1 min

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. ...

Do They Know it’s (not) Christmas Time at All?

Published: February 21, 2010 Reading time: 1 min

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. ...
