[markus_81]

Tuytto è iniziato con l'arrivo di molte mail da parte dei miei client di posta elettronica, wooow.it e virgilio.it
Vi riporto alcune di queste mail

e cosi via

sbagliando la prima volta che mi è arrivata ho aperto l'allegato e da quel momento sono iniziati i guai.
I sintomi che ho sono questi: ad ogni avvio mi trovo il firewall di winxp disconesso, non mi apre più il taskmanager, non mi apre più l'antivirus (Norton aggiornatissimo), non mi apre più il comando regedit e msconfig da esegui
Aparte questo però non noto altri problemi se non un invio di dati molto elevato durante la connessione internet ( ho un 56k che uso di tanto i tanto ). La cosa più grave è che non riesco più ad inviare messaggi di posta, tornano tutti indietro....come mai

Che potrebbe essere? E'grave ? Mi conviene formattare

Posto poi il file txt che mi si è aperto con l'allegato

MZkernel32.dllPEL

[andorra24]

Mi insospettiscono queste 2 voci:
C:\WINDOWS\system32\skynew.exe
O4 - HKLM\..\Run: [WINDOWS SYSTEM] skynew.exe

Praticamente non si trova nessuna info su questo skynew.exe e questo e' strano.

[andorra24]

Puoi sicuramente fixare le 2 voci che ti ho scritto sopra.

[bluepix]

Credo che ti sia beccato il worm Mydoom.
Qui trovi il removal tool :

Fatto...

Guardando la lista dei virus ho visto questo che ha a che forsew può avere a che fare con quel skynew



WORM_NETSKY.P

--------------------------------------------------------------------------------

Tipo: Worm
Alias: W32.Netsky.P@mm!enc
In circolazione: Sì
Dannoso: Sì
Lingua: English
Piattaforma: Windows 95, 98, ME, NT, 2000, XP
Crittografato: No
Grado di rischio complessivo Medio

--------------------------------------------------------------------------------

Infezioni individuate: Medio
Potenziale di danno: Alto
Potenziale di distribuzione: Alto


--------------------------------------------------------------------------------

Description:

This NETSKY worm spreads by sending out copies of itself as email attachment using its built-in SMTP engine. It gathers target recipients from certain files found on the affected machine, virtually turning the affected system into a propagation launch pad.

The email it sends out has a spoofed sender's name, varying subjects, message bodies and attachments, and generally mimics email delivery notifications. For complete details about the email that this worm sends out, please click here.

To extend its reach and maximize its distribution potential, this worm employs the following:


Social engineering
Like most mass-mailing worm programs, this worm employs social engineering to get through that most critical barrier to propagation, which is getting the target recipient to open the infected email and execute the attachment.

It uses an email message that takes the form of an email delivery notification (which is typical of most NETSKY worms) to trick the user into thinking that the email is from a valid source. Social engineering not only aids the worm in getting the target recipient to open the infected email, it also allows the worm to evade content filters or scanners.

For complete details about the email that this worm sends out, please click here.


Built-in SMTP engine
This worm also uses its built-in SMTP (Simple Mail Transfer Protocol) engine for easy propagation, allowing the worm to send email without having to rely on other email applications to spread. Most mass-mailing worm programs have built-in SMTP engines to facilitate easy propagation.


Incorrect MIME Header Vulnerability (MS01-020)
This worm also exploits the Incorrect MIME Header vulnerability to propagate. The vulnerability allows the automatic execution of attachments, while an email is viewed or previewed and affects Internet Explorer 5.1 and 5.5.

For a detailed discussion of the Incorrect MIME Header Vulnerability, please consult the following Microsoft page:


Microsoft Security Bulletin MS01-020
This worm also tries to propagate via peer-to-peer networks by searching drives C to Z for folders that contain strings that are mostly associated with peer-to-peer aplications.

It deletes several autorun registry entries to prevent the automatic execution of different variants of the following worms:

BAGLE
NACHI
MYDOOM
DEADHAT
This worm usually arrives UPX- and FSG-compressed to prevent easy detection. It runs on Windows 95, 98, ME, NT, 2000, and XP.

Note: Trend Micro also detects empty email messages from this worm as WORM_NETSKY.P, and the HTML file containing the exploit as HTML_NETSKY.P. The email and the HTML file may contain a damaged attachment or no attachment at all. At any case, no malware file will be executed.

Credo che ti sia beccato il worm Mydoom.
Qui trovi il removal tool :

e qui una descrizione:

A tutte e sue i link mi da impossibile visualizzare la pagina, immediatamente appena clicco sul link.
E' il virus che me lo impedisce??

[andorra24]

Il secondo log mi sembra a posto.

[andorra24]

Ti consiglio di tenere il sistema operativo aggiornatissimo e patchato e di usare un buon antivirus.

[markus_81]

Ho cancellato le due voci e tutto è tornato a funzionare alla meraviglia..

Un'altra cosa: le e-mail continue che mi arrivano quando smetteranno, c'è modo di fermarle, me ne è arrivata prprio adesso un'altra con scritto in stampatello YOUR ACCOUNT IS SUSPENDED
Che faccio?

[bluepix]

Ehmmmmm credop proprio di si , devi controllare il file Hosts che si trova a questo indirizzo:

c:\windows\system32\drivers\etc

per non essere corrotto deve contenere solo queste righe:



# Copyright (c) 1993-1999 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host

127.0.0.1 localhost

[markus_81]

Ti posto la schermata che trovo, non c'è niente di quello che dici te

[bluepix]

Scusami, devo essermi espresso malamente.

E' il contenuto del file:c:\windows\system32\drivers\etc\hosts
che deve contenere quelle righe.
Tieni conto che le righe che iniziano con # sono righe di commento

[markus_81]

Allora trovo questo, sembra simile a quello che dici te....quindi

[bluepix]

perfetto !!!!!!!!!
