| Discovered: | 2004 Aug 09 |
SYMPTOMS:
Presence of file %SYSTEM%\\WINdirect.exe.Presence of file %SYSTEM%\\windll.exe.
Presence of registry key HKLM\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run\\win_upd.exe = %SYSTEM%\\WINdirect.exe or
HKCU\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run\\win_upd.exe = %SYSTEM%\\WINdirect.exe.
Presence of registry key HKCU\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Ru1n.
TECHNICAL DESCRIPTION:
The worm comes in the form of a small file, that drops another file ( namely WINDirect.exe) in the %SYSTEM% directory.This file then tries to raise it\'s privilege level and then starts a thread in which it keeps looking at all the processes and when it finds one within a list ( in order to prevent updating an AV product or the use of a firewall ) it tries to terminate it. Then it starts another thread that tries to download the main part of the massmailer from a list of addresses, each 10 hours.
The main part of the worm creates mutexes named MuXxXxTENYKSDesignedAsTheFollowerOfSkynet-D, \'D\'r\'o\'p\'p\'e\'d\'S\'k\'y\'N\'e\'t\', -oOaxX|-+S+-+k+-+y+-+N+-+e+-+t+-|XxKOo-_, [SkyNet.cz]SystemsMutex, AdmSkynetJklS003, ____--->>>>U<<<<--____ and _-oO]xX|-S-k-y-N-e-t-|Xx[Oo-_ in order to prevent some Netsky versions from running.
It also tries to delete from the system startup registry keys any key that contains one from a list of strings ( such as \"FirewallSvr\", \"ICQNet\", \"My AV\" and so on ).
It also checks for files that may contain e-mail addresses in files of the type \"wab\",\"txt\",\"msg\",\"htm\",\"shtm\",
\"stm\",\"xml\",\"dbx\",\"mbx\",\"mdx\",\"eml\",\"nch\",\"mmf\",\"ods\",\"cfg\",\"asp\",\"php\" etc.
It uses it\'s own SMTP client implementation.
The mails it sends contain only the first dropper, called one of \"price\",\"price2\",\"price_new\",
\"price_08\",\"08_price\",\"newprice\",\"new_price\" in a .zip archive .
The mail body contains \"new price\". The archive may be encrypted, so the body of the mail contins the password. The mail has the subject empty.
This worm can also take advantage of P2P networks, as it tries to spread using the following names:
\'Microsoft Office 2003 Crack, Working!.exe\',
\'Microsoft Windows XP, WinXP Crack, working Keygen.exe\',
\'Microsoft Office XP working Crack, Keygen.exe\',
\'Porno, sex, oral, anal cool, awesome!!.exe\',
\'Porno Screensaver.scr\',
\'Serials.txt.exe\',
\'KAV 5.0\',
\'Kaspersky Antivirus 5.0\',
\'Porno pics arhive, xxx.exe\',
\'Windows Sourcecode update.doc.exe\',
\'Ahead Nero 7.exe\',
\'Windown Longhorn Beta Leak.exe\',
\'Opera 8 New!.exe\',
\'XXX hardcore images.exe\',
\'WinAmp 6 New!.exe\',
\'WinAmp 5 Pro Keygen Crack Update.exe\',
\'Adobe Photoshop 9 full.exe\',
\'Matrix 3 Revolution English Subtitles.exe\',
\'ACDSee 9.exe\'.
by copying into each folder that contains \'shar\'.
The worm also opens a connection that listents on port 80, but since this is the default port used by HTTP, this should not be used as an infection flag ( unless you are very sure you have no HTTP server installed ).

H2 2011 E-Threat Landscape Report - Overview
Twenty years ago, a revolutionary means of electronic communication was born. It would become so popular with all ages and professions that it is still the most used data communication mechanism even today: introducing the SMS – the short message service.
Today, mobile phones are more than bulky gadgets that can move voice and messages from one point to another: they are must-have gear in a World 2.0 – so powerful and so complex, running their own operating systems and, consequently, facing their share of cyber-trouble. While the first six months of 2011 were marked by software vulnerabilities and high-profile data breaches, the second half cast the spotlight on not only a new family of malware, but also uncovered a user espionage scandal that apparently involved an array of mobile phone carriers and the controversial software vendor CarrierIQ.
The malware landscape was dominated by Trojan.Autorun.Inf and Win32.Worm.Downadup, two malicious contenders that have roots in the Windows XP era, but managed to keep their places even though operating system upgrades or applying patches would have solved security issues exploited by these pieces of malware. The top contenders for H2 2011 are Trojan.AutorunInf, Win32.Worm.Downadup, and Exploit.CplLnk.
Data breaches attributed to the Anonymous gang and its satellite hacking groups continued throughout the second half of 2011. Among the most important targets were Mitsubishi Heavy Industries, Adidas, RIM, Tiroler Gebietskrankenkasse, Nexon and even the United Nations. Corporate trust also came under close scrutiny, as the DigiNotar incident in H1 2011 exposed unwary users to a massive phishing attack that used stolen digital certificates generated for high-profile institutions and government agencies such as Google, Tor, CIA and Israel’s Secret Service, the Mossad.
Social networks have also played a key role in disseminating malware and spreading fake news about the deaths of high-profile personalities such as Muammar Gaddafi or Steve Jobs. Of particular importance were the malicious campaigns built around the alleged movie of Gaddafi’s execution and the commemorative giveaway in honor of the late Steve Jobs.
