Below is a recap of events: There was a sharp incline in exploit activity for new vulnerabilities this period: we detected attempted exploit activity on 61% of new vulnerabilities covered by FortiGuard Labs. Typically this rate falls between 30-40%. Nearly 1/2 of those vulnerabilities rated as 'Critical' (remote code execution) were attacked. As an ongoing reminder, it is imperative to help secure systems against such exploitation by keeping all software... [Read More]

It's the beginning of 2011, which means network security vendors’ threat predictions for the year to come have mysteriously appeared in their crystal balls by now. Making informed security predictions can be an easy or difficult task depending on the approach taken. The easy way out is to look back at the biggest trends of the last year and talk about how they will continue into the next. The idea is to keep the prediction vague and difficult to verify in case the prediction ultimately turned out to be off the mark. Writing useful and verifiable... [Read More]

Our analyst, Ruchna Nigam, had been analyzing a sample of SymbOS/InSpirit.A!tr.

The malware simply added a new SMS in the victim's inbox, apparently coming from the bank's service hotline phone number, and telling the victim he/she had entered a bad password and needed to follow a given (malicious) link to guarantee...

The last threat report for 2010 is up on our FortiGuard Center. Below is a recap from the report: As we enter the holiday season, spam rates continue to drop after a sharp decline following Bredolab's takedown in October/November 2010. Global spam rates throughout December were, on average 7% lower than November and about 19% lower than the peak before Bredolab's takedown in October. This is welcoming news, since we have seen a noticeable impact that has lasted for two months now. Spam rates decline simply because the volume of spam declines, mostly... [Read More]

This vulnerability is a kernel buffer overflow which exists in NDProxy.sys, a device driver interfacing mini-ports to the telephony API (aka TAPI). The vulnerable code is brought up when issuing a DeviceIoControl call from “userland” with control code 0x8ff23c8. This ioctl call is related... [Read More]

A while ago, probably after a long and difficult day, I got into this funny idea of encrypting my Facebook account messages so that only the people I really wanted to could read them (i.e not an unknown stranger using Firesheep, nor a third-party applications or not even Facebook itself). For a moment, I wondered how to do this, until I remembered a Firefox plugin named FireGPG. Basically, FireGPG is Firefox extension to GPG, i.e it enables easy encryption/ decryption/ signature/ and verification in the browser. So, I installed the plugin and tried... [Read More]

Although it is difficult to prevent a widespread DoS or DDOS attack from affecting your network operations,... [Read More]
