Skulls.L - Pretends to be pirated version of F-Secure's Mobile AV product

  This new variant of the Skulls mobile phone virus appears to be a free “pirated“ copy of F-Secure's Anti-virus product for Mobile phones.  Besides the legal and ethical considerations for using pirated copies of software, this new virus will lock the phone permanently until cleaning is accomplished by buying the real product.  This social engineering scheme illustrates the dangers of installing free software offered by email, instant messaging, or other sources.

Links related to this new virus are noted below:

Skulls.L - Pretends to be F-Secure's Mobile AV product

F-Secure's Web Log Description

Skulls.L is a variant of SymbOS/Skulls.C trojan. The component files of the trojan are almost identical to Skulls.C. The main difference between Skulls.L and Skulls.C is that Skulls.L pretends to be a pirate copied version of F-Secure Mobile Anti-Virus.

  REMOVAL Techniques

Secunia Advisory - Mozilla Frame Injection Vulnerability

  Secunia has issued a moderately critical advisory for Mozilla browsers including Firefox 1.04 for a Frame Injection Vulnerability.  This new vulnerability has not been exploited in-the-wild and can only occur while processing a trusted and hostile web site at the same time.  Firefox users should look for an upcoming release and always be careful of sites visited and email URL links.

ZdNet Article: Mozilla Frame Injection Vulnerability

A 7-year-old flaw that could let an attacker place malicious content on trusted Web sites has resurfaced in the most recent Firefox browser, Secunia has warned.  The flaw, which also affects some other Mozilla Foundation programs, lies in the way the software handles frames, which are a way of showing Web content in separate parts of the browser window.

As a result, an attacker could insert content into a frame on a trusted Web site, Secunia said. Account holders who believe they are interacting with a frame belonging to an online bank could be tricked into giving up personal information or downloading malicious code, for example. Secunia rated the issue "moderately critical." The same "frame injection" vulnerability in Mozilla's browsers was detailed by Secunia in July of last year. At the time, it did not affect the most recent versions of the applications.

For a spoofing attempt to work, a surfer would need to have both the attacker's Web site and a trusted Web site open in different windows. A click on a link on the malicious site would then display the attacker's content in a frame on the trusted Web site, Secunia said. The company advised people not to visit trusted and untrusted Web sites at the same time.

 

Secunia Advisory - Mozilla Frame Injection Vulnerability

Moderately Critical:  

Description:  A seven year old vulnerability has been re-introduced in Mozilla and Firefox, which can be exploited by malicious people to spoof the contents of web sites. 

Secunia Browser Frame Injection Vulnerability Test

The vulnerability has been confirmed in Firefox 1.0.4 and Mozilla 1.7.8. Other versions may also be affected.

Solution: Do not browse untrusted web sites while browsing trusted sites.

 

Mozilla Support Forums Information

The vulnerability has not been exploited, a moderator of a support forum on the Mozilla Web site wrote Monday, in response to the Secunia alert.  For protection, the moderator advises people to close all other windows and tabs before accessing a Web site such as a bank or online store that requires them to type in personal data.

MS04-007: RBOT variant - 1st worm to exploit ASN.1 via Internet

Kaspersky's weblog entry of June 5th entitled "Robots,vile robots everywhere!" is a great read

MS04-007: RBOT variant - 1st worm to exploit ASN.1 via Internet

Investigation of the packets revealed a Microsoft ASN.1 exploit, which tries to download and run an executable from the attacking machine via TFTP. We've secured a binary and took a look under the cover. The responsible worm was a Rbot variant, ...

Besides the ASN.1 exploit - and this is the first worm to use it successfully on the Internet - the Rbot variant uses a multitude of other exploits, DCOM, RPC,Veritas Backup Exec, LSASS, MSSQL, password guessing and so on. It also steals registration keys from a good list of popular games, PayPal accounts logins, has an embedded backdoor and of course, DDoS capabilities.

Basically, it's a worm which tries very hard to spread while at the same time, it tries to steal as many valuable data from the victim machine as it is available. It is a highly infectious worm, written for profit. And yes, most of the other worms we're seeing nowadays are no different.

Spybot.PKC - May be a close example of the new RBOT variant

Downloader.ABL (aka Small.AHE) - MEDIUM RISK (Osama virus)

  Trend/Secunia also declared MEDIUM RISK on Troj Small.AHE, which is different than Bobax.P, but centers on the same theme.

For users, it's essential to AVOID attachments from ANY politically themed email, as that's often a common social engineering threat (like we saw with the German Sober.Q spam)

Turn on your TV. Osama Bin Laden has been captured. While CNN has no pictures at this point of time, the military channel (PPV) released some pictures. I managed to capture a couple of these pictures off my TV. Ive attached a slideshow containing all the pictures I managed to capture. I apologize for the low quality, its the best I could do at this point of time. Hopefully CNN will have pictures and a video soon. God bless the USA! Stephen Christensen

Ad-Aware SE Personal Edition 1.06 available

  Ad-Aware SE Personal Edition 1.06 is an excellent adware and spyware removal tool that is free for personal use.  The following provide some key links from download.com:

Ad-Aware SE Personal Edition 1.06 - Information

Download Site - Version 1.06

  Download.com Review of Ad-Aware SE Personal Edition

5

One of the first applications built to find and remove adware and spyware, Ad-aware SE Personal Edition's excellent reputation is well justified. The sky-blue, skinnable interface features five buttons. The first two, Status and Scan, lead to the core function of the application. These buttons initiate a scan of your files for adware components. After scanning is complete, the program presents a summary of results, followed by a list from which you select exactly which components to remove. Right-clicking an individual entry gives some information about the piece of suspected adware, though we would like more details. Ad-aware SE can alert you to more malignant forms of malware by separating items into critical and negligible categories. The third button, Ad-watch, is nonfunctional in the Standard version. The fourth button, Plug-ins, shows you which Ad-aware plug-ins are installed. The fifth leads to the help files.

Ad-aware SE does an excellent job of quickly finding and removing most adware and spyware components, although you will have to restart and rescan for a seriously infected machine. We were pleased to see an auto-update feature included with the program, keeping Ad-aware up-to-date with the latest adware components. Ad-aware SE should be part of your arsenal for keeping your machine free of adware and spyware components.

Spybot Search & Destroy version 1.4 available

  Download.com Review of Spybot - Search & Destroy

5

The latest version of Spybot - Search & Destroy adds some truly useful features to an already excellent application. The program still checks your system against a comprehensive database of adware and other system invaders, but it works much faster now. It also features several interface improvements, including multiple skins for dressing up its appearance. Scan results now appear arranged by groups in a tree, and a sliding panel lets you instantly view information about a selected item to help you decide whether to kill it or not. The Immunize feature blocks a plethora of uninvited Web-borne flotsam before it reaches your computer. Other useful tools, including Secure Shredder, complement the program's basic functionality for completely destroying files. Hosts File blocks adware servers from your computer, and System Startup lets you review which apps load when you start your computer. The functionality makes Spybot - Search & Destroy a must-have for all Internet users, and this version is a worthwhile upgrade.

Mytob.BI - Poses as an IT Administrator

The social engineering, advanced code, attack methods, and the ease in building new variants makes this family among the worst.  Users must keep their AV protection updated daily to keep up with new threats.

Mytob.BI - Poses as an IT Administrator

The Mytob.BI variant prevents the infected machine from accessing several antivirus and security Web sites by redirecting the connection to a local machine, the security company added. While prevalence of the worm is still low, the damage potential is high, Trend Micro said. U.K.-based antivirus company Sophos PLC also rated the worm as a concern, due to the severe damage it could cause.

Researchers speculated that the Mytob worm family is popular with hackers because its code base is relatively easy to manipulate to create a new variant. Another version, Mytob.ar, was detected earlier this week, containing added spyware and adware elements.

The worm poses as a message from an IT administrator, warning recipients that their e-mail accounts are about to be suspended, Trend Micro said. Possible subject headers for the worm include "*IMPORTANT* Please Validate Your Email Account" and "Notice: **Last Warning**."

MESSAGE LABS - SPECIAL ALERT


 New Bagle Downloader spreading like wildfire via email

31 May 2005 – MessageLabs is warning computer users to be on their guard against a new variant of the Bagle downloader. MessageLabs has intercepted almost 70,000 copies already. The first copy was intercepted today at 13:24 GMT (14:24 BST). 45,769 copies have been stopped in the last hour (3-4pm BST). The virus appears to have originated from a Yahoo group.

The as yet unnamed Bagle downloader variant drops a trojan that attempts to download Bagle from a vast list of locations. Computer users who activate the file attached in the email invoke the virus, which harvests email addresses it finds on the computer's hard drive. The virus then forwards itself onto the list of email addresses it has discovered in infected computer.
