Best Way To Change Sim without code

Way to change sim without code.

1 - put your new sim card inside the phone, but not totaly plugged (the phone don't see the sim and boot without)
2 - put the batterie on but leave a little space to push forward the sim at the end
3 - boot the phone, it will say 'no sim'
4 - push the sim with something slim (a knife ie)
5 - reset the phone with the hard reset code *2767*3855#

additional step apply to the instructions above: when the phone prompt for a code, type 0000 first, optionally after that one the code of the simcard.

that's it.
Don't let the phone turn off, or you will need to re-do the same task again.

Real Hacking Steps (Remote Hacking):)) For Educational Purposes Only

Real Hacking Steps consists of following:::

1. Information Gathering / Foot printing
2. Port Scanning
3. OS Fingerprinting
4. Banner Grabbing
5. Vulnerability Assessment
6. Search & Build Exploit
7. Attack
8. Maintain Access with help of Root kits and Trojans.

1. Information Gathering / Foot printing

Information gathering is the process to get maximum details of target host. It is a very important

part of remote hacking because the more information about target system we have, more the number of

attacks we can launch.

2. Port Scanning

What is port?

Port is medium for communication between 2 computers. Every service on a host is identified by

a unique 16-bit number called a port.

Some default ports:

Port number Service::

7 Ping

21 FTP(File transfer protocol)

22 SSH (Secure shell)

23 Telnet

25 SMTP (Mail)

43 WHOIS

53 DNS

80 HTTP

110 POP3 (Mail Access)

513 Rlogin

8080 Proxy

What is port scanner?

A port scanner is a piece of software designed to search a network host for open ports. This is often used
by administrators to check the security of their networks and by hackers to identify running services on a
host with the view to compromising it. To portscan a host is to scan for listening ports on a single target
host. To portsweep is to scan multiple hosts for a specific listening port.
Best port scanners: nmap, Hping2, Superscan.

3. OS Fingerprinting

OS (Operating System) Fingerprinting is a process to find out victim's Operating
System(Windows, Linux, UNIX)

Introduction:

When exploring a network for security auditing or inventory/administration, you usually want to
know more than the bare IP addresses of identified machines. Your reaction to discovering a
printer may be very different than to finding a router, wireless access point, telephone PBX,
game console, Windows desktop, or Unix server. Finer grained detection (such as distinguishing
Mac OS X 10.4 from 10.3) is useful for determining vulnerability to specific flaws and for
tailoring effective exploits for those vulnerabilities.
Tools: nmap, NetScanTools Pro, P0f.

4. Banner Grabbing

Banner grabbing
or application. Mean after port scanning we found open port 80 (apache) and target os is Linux,
but we don’t know what is version of apache for remote hacking. Like apache 2.0, 2.2, or 2.6 .

5. Vulnerability Assessment

What is Vulnerability Assessment?

The word "
misconfiguration) that allows a system to be attacked or broken into.
vulnerability" describes a problem (such as a programming bug or common
A vulnerability assessment
ranking) the vulnerabilities in a system.
Vulnerability assessments can be conducted for small businesses to large regional infrastructures.
Vulnerability from the perspective of Disaster Management means assessing the threats from
potential hazards to the population and to the infrastructure developed in that particular region. It can be
done in political, social, economic and in environmental fields.

is the process of identifying, quantifying, and prioritizing (orAutomated Tools:

6. Search & Build Exploit

Manual Method: We can find vulnerability manually with help of vulnerability archive sites like
www.milw0rm.com
and http://www.packetstormsecurity.org/
For exploit and final attack, open the websites say Microsoft, adobe or mozilla which provides
you the source code format. You need to download the code and compile them for preparing
exploit for final attack
.
7. Attack
Launch attack on remote system and get reverse shell
.
8. Maintain Access
After getting remote access we place a root kit or Trojan virus for future remote access, without
any password.

9. Covering Tracks

Covering Tracks is a process to delete all logs on the remote system. If target system is linux or
UNIX, delete all entries of /var folder and if it is windows os delete all events and logs.

Mail Server Internet Deployment Checklist

Before deploying your new mail server on the internet, make sure you have checked the list below. This will ensure that your mail server will have a good sending reputation (trusted) and will not be ignored and treated as a spammer.

Your IP addresses are not blacklisted

Even a newly setup mail server could already be blacklisted. Some of the reasons are:

For those using a dedicated server, the IP address given to you might have been used by a spammer in the past
For those using a shared server, a fellow user might have sent a spam mail.
For those using NAT to share internet connection, one of your users might have sent a spam mail due to virus infection

To check if your IP address is blacklisted, use
http://www.mxtoolbox.com/blacklists.aspx

Your mail server has an MX record

An MX record or Mail exchanger record is a type of record in the Domain Name System (DNS) specifying how Internet e-mail should be routed using the Simple Mail Transfer Protocol (SMTP). Contact your DNS provider to add an MX record for your new mail server. To check if your mail server has an MX record, use http://www.dnscolos.com.

Your mail server greeting matches your hostname

To test your mail server greeting, use http://www.dnscolos.com. If your mail server has multiple IP addresses, see Postfix Multiple IP Addresses Individual SMTP Greeting for a guide on how to fix this issue.

Your mail server is not open relay

An open relay mail server allows anyone to send mail outside your network. This means any Tom, Dick and Harry can use your mail server to send spam. To perform an open relay test, use http://www.dnscolos.com. If it fails, double check your Postfix Dovecot SASL configuration.

Your mail server has a reverse DNS

A reverse DNS returns the hostname given the IP address. Most mail servers will check if you have a valid reverse DNS, otherwise your sending reputation will be downgraded. Contact your internet service provider to add reverse DNS entries for your mail server IP addresses. To check if your mail server has a reverse DNS, use http://www.dnscolos.com.

Create a SPF DNS record if possible

Sender Policy Framework (SPF) allows software to identify messages that are or are not authorized to use the domain name based on information published in a sender policy of the domain owner. Not all DNS provider supports SPF so choosing a DNS provider that can do this is a plus. To check if your mail server has an SPF record, use http://www.dnscolos.com.

Postfix Quota for redhat mail user

Postfix does not support mailbox quota. But thanks to Anderson Nadal’s Postfix Virtual Delivery Agent (VDA) patches, it can. To use the Postfix VDA requires two things, first Postfix must be built with the VDA patches and second, virtual user accounts must be used. You can get the Postfix RPM with VDA patches here.

Here are some configuration you can use for your virtual accounts.

Configure Postfix VDA

1. Edit the postfix configuration file /etc/postfix/main.cf and add the lines below

virtual_mailbox_limit_override = yes
virtual_overquota_bounce = yes
virtual_mailbox_limit_maps = hash:/etc/postfix/vquota

2. Create the file /etc/postfix/vquota containing the mapping from an email address to the maximum mailbox quota in bytes. If you wish to be exact, 1KB equals 1024 bytes while 1MB equals 1024KB or 1048576 bytes.

johndoe@acme.local 10485760
janedoe@acme.local 2097152

John Doe got a 10MB quota while Jane Doe got 2MB.
After creating this file, execute postmap /etc/postfix/vquota. This will generate /etc/postfix/vquota.db, the actual file that will be used for the lookup.
Note

If you use Active Directory as your Postfix virtual user accounts source, you can use the maxStorage attribute instead to store the quota. Just copy your ldap-users.cf configuration and save it as ldap-quota.cf. Next change samaccountname to maxstorage in the result_attribute line and remove the result_format line. In your main.cf, use ldap:/etc/postfix/ldap-quota.cf as your virtual_mailbox_limit_maps. In Windows, you can use ADSI Edit to access and modify the value of maxStorage.

3. Restart the Postfix or MailScanner service if you have installed MailScanner. Learn how to start and stop services here.

4. Test Postfix using Telnet. Try using a very small quota limit so you can test the quota feature.

Postfix Aliases and Mailing List for redhat 6

You can create a text file in Postfix containing an alias email and several destination emails. There are two ways to implement aliasing and mailing list in Postfix depending on how it is configured.

For System Accounts

Your Postfix is configured to use system accounts if your configuration file has something like

mydestination = $mydomain

or sending to a non-existent account gives the error message

Recipient address rejected: User unknown in local recipient table

1. Edit the file /etc/aliases. The file has the form

alias: address1,address2

If address has the same domain as yours, you can leave it out. Thus you can use the /etc/aliases file to alias an email address or to build a mailing list.

2. Type in the command newaliases in a terminal window. This will rebuild the aliases database file.

For Virtual Accounts

Your Postfix is configured to use virtual accounts if your configuration file has something like

virtual_mailbox_domains = $mydomain

or sending to a non-existent account gives the error message

Recipient address rejected: User unknown in virtual mailbox table

1. Edit the file /etc/aliases. The file has the form

alias address1,address2

2. Generate the database file for valias using the command

postmap /etc/postfix/valias

3. Test your database file using the command

postmap -q group@acme.local /etc/postfix/valias

Replace group@acme.local with a valid alias entry. You should see the destination emails.

4. Edit the file /etc/postfix/main.cf and add the line below to your virtual settings section

virtual_alias_maps = hash:/etc/postfix/valias

If you are using virtual accounts, instead of maintaining a text file containing the aliases and mailing list, it would be better if you can work with your virtual accounts source. See the links below for examples

To Test Postfix

1. Restart the Postfix service. But if you installed MailScanner, then restart MailScanner instead. This will immediately reload the aliases database file instead of after a few minutes.

2. You should now be able to send email to addresses found in your aliases file. See Test Postfix using Telnet and try using the alias email addresses
