Malware when oracle connection attempt
I tried to act as a malicious user on my own database on my PC just for the sake of experiment. I tried the following steps:
I am connected to the database with the help of scott as sysdba user. Then I gave the default password of the user scott, whose "Tiger." Then
surprisingly, I was able to connect as user SYS. I'm now having the user SYS privileges. I can be destroyed the entire base.
The question is why I was able to connect as user SYS by using the username 'scott as sysdba' with scott password 'tiger '? How
to prevent such a thing for safety?
Thank you in advance!
Respect,
Mussa.

Dynamic JDBC: account blocked after the single connection attempt
Our database is set up so that user accounts are locked after 3 bad connection attempts, but they're getting locked after only 1 attempt. I would like that it so that any attempt to connect ADF would be only created an Oracle connection attempt.
I use JDeveloper 10.1.3.4.0 and by default, right click and then run.
Code of the not yet documented Steve Muench ADF application examples at http://blogs.oracle.com/smuenchadf/examples/#14
which is also described in http://www.oracle.com/technology/products/jdev/howtos/10g/dynamicjdbchowto.html
Looking at the audit trail, I see the database tries to connect 5 times than the user.
Trying to debug, I see that the doFilter in ADFBindingFilter is also called 5 times.
In my research, I read the proposals that it might be the framework that tries to connect several times. It depends on the connection pooling and application module pooling settings you have.
But I tried searchign in JDeveloper and don't see not where I set or change anything on reunification.
Thank you
JeffOracle has finally acknowledged it is a defect of jdeveloper and entered
Bug 9153659: JDBC DYNAMICS IDENTIFICATION ACCOUNT LOCKS AFTER 1 FAILED CONNECTION information
And I have no idea how oracle reactive is subject of fixed bugs, but since the last version of jdeveloper 10 numbered fixed iin bugs 5 millions, I guess that this will never be corrected. -

The files are all created in C:\windows\temp\tmp0000xxxx\ and are called tmp0000yyyy. There is no file name extension and the file size is 0 KB to MB in size. They are created at a pace that can reach 100 000 per hour and take 6 GB of space per hour. It really slows the PC and a pain to deal with
First of all, there was also a perflib_perfdataxxx.dat file as well, but I find this return to a java jsq.exe file. I got rid of this help Unlocker and it was OK for a week and now she went back worse than ever. I can delete the files using cleaning, but they keep coming when I connect. I am on Windows XP and the BitDefender antivirus (recently updated for 2012) are Microsoft Security Essentials - which none has detected a virus. One other strange thing has been lately that BitDefender did not Excel files for a while because he thought he has access to the internet so I had to turn off the feature in BitDefender (sorry don't remember the name). I saw a few notes on web chat that Excel can create .tmp files
Any help would be appreciated.
OK - off BitDefender and all seems well. Don't be that charge again! All about Microsoft Security Essentials now so I hope that's enough with the firewall.
May not be entirely incompatibility of anti-virus software, as this was happening before that I put on MSE, in a desperate attempt to find a virus.All I can say is that on an old PC, I had Norton mess up so I ran that 4 years without antivirus and never had any problems. My opinion is that the antivirus is a scam! -
Computer "not responding" when I connect the external hard drive.
Hi all
When I connect my external hard drive to my laptop, it is detected and the icon for the material appears in the taskbar background. But when I go to my computer, it happens that does not. I can always open other programs etc that are not related to the hard drive, but nothing to do with the hard drive "fails". As soon as I plug it on, the laptop starts responding again. I tried it on another laptop and the same thing happens.
Any ideas?
Hi Wendall81,
-How long have you had this problem?
Follow the steps below:
Method 1:
Step 1: Boot in safe mode and check if the problem persists.
See Advanced startup options (including safe mode) for more information about starting in safe mode.
Step 2: If the problem does not occur in safe mode, you can put your system to boot (in normal mode) to solve the problem.
See How to solve a problem by performing a boot in Windows Vista or in Windows 7
Note: After troubleshooting, be sure to set the computer to start as usual as mentioned in step 7 in the above article.
Method 2:
Run a check disk on the external hard drive.
For instructions, see check your drive for errors .
Note: If any bad sectors are found by running the check disk utility and recovery of the attempt of bad sectors option is checked when checking the disk for errors, data in the bad sector can be lost as they tried to recover bad sectors. Gokul - Microsoft Support

USB device not recognized when I connect my iphone to my computer
Original title: USB device not recognized
I get the error message "Unrecognized USB device" when I connect my iphone to my computer. It is the same as the one I use for months. Same computer. Same sync cable. I have changed everything, including hang iphone to my wife instead of mine and get the same message. I also did a restore on my computer that doesn't change anything.
Hello
At this point, I think it's a good idea to run a scan for viruses/malware on the PC with the anti-virus software that you have installed.
Also, if you haven't already, I would try removing the USB controllers and restart again, now that the updates of Windows are installed. Don't forget, you can even download the drivers directly from manufacturer support site for your PC, if they install automatically when you restart after their removal.
Finally, take a look at the thread I linked below. The first answer is quite similar to that mentioned above in this thread, but there are also a few other really good measures listed there as well. Then take a look at the linked thread and see if that helps at all.

Monitoring VPN connection attempts
I would like to be able to use the syslog messages that are detached from the ASA to monitor VPN connection attempts (successful or not). Looking at the posts system there are several codes that relate to this.
I wonder if anyone has a good way to use syslog to do this? There are some codes that can be used for this information?
Thank you.
You can set the ASA to send syslog messages when the user connects and disconnects. There are a few types of 'remote access' as IPsec VPN, webvpn / without client anyconnect/ssl vpn client that you can follow.
If you are using Clientless SSL VPN syslogs usually begin with 716xxx. For example the syslog for connect is 716001 and disconnect is 716002. There is a list of other Clientless VPN SSL related messages here. You can view the specific contents of each journal here:
http://www.Cisco.com/en/us/docs/security/ASA/asa80/system/message/logmsg
http://www.Cisco.com/en/us/docs/security/ASA/asa80/system/message/logmsgs.html#wp4776913
If you use SSL VPN Client (SVC1.x, AnyConnect 2.x) syslogs usually begin with 722xxx. For example, the syslog for connect is 722022 and disconnect is 722023. There is a list of other customer VPN SSL related posts here
http://www.Cisco.com/en/us/docs/security/ASA/asa80/system/message/logmsg
http://www.Cisco.com/en/us/docs/security/ASA/asa80/system/message/logmsgs.html#wp4778697
If you use the IPSec VPN client, you can follow a success to connect with 713119 (indicates the phase 1 completed), 713049 (indicates the complete Phase2) and disconnect with 113019. There is a syslog ipsec additional 713049 that you can follow for ipsec.

http://www.Cisco.com/en/us/docs/security/ASA/asa80/system/message/logmsgs.html#wp4769539
Here are some other notes to keep in mind:
-You can tell that the logging levels you currently have on the command line ASA with 'show log '.
-Newspapers that you send to a syslog server are controlled with the commands "Logging Trap". For example 'logging trap information' (level 6) or "trap alerts logging" (level 1)
-You can tell what level of severity (i.e., alerts, critical, errors, warnings, notifications, informational, debug) each one connects through this link. As you can see by checking the link, those follow-up sign in or out as I've mentioned above are usually information (sev 6)):
http://www.Cisco.com/en/us/docs/security/ASA/asa80/system/message/logsev
http://www.Cisco.com/en/us/docs/security/ASA/asa80/system/message/logsevp.html
-If you want to create a specific subset of the syslogs to send to a specific device, you can do it with a class or a list of logging:
http://www.Cisco.com/en/us/docs/security/ASA/asa80/configuration/guide/m
For example (class log):
http://www.Cisco.com/en/us/docs/security/ASA/asa80/configuration/guide/m

For example (list of logging):

Connection attempts that have failed maximum AnyConnect on the LDAP Windows database
Hello
I can't seem to find the setting for the Web and client Anyconnect set connection attempts that have failed maximum when on the LDAP in Windows database.
I would say that after that maximum 3 attempts to connect the possebility to connect again times out for 10 minutes.
Now it is possible to log in as often as you want, which is a big security problem.
Please, I can use some help to achieve this, thanks in advance.
Best,
Orson
I don't think that this can be configured in AnyConnect or on the ASA. They both rely on the settings on the Windows Server. We can fix this. (reference)

When I connect to the internet, servads pop up. I ran malwarebytes anti malwalre and microsoft security analysis. Not found the problem of servads in their analyses. How can I get rid of the servads.
Hello
1. what web browser do you use?
2 have had any changes made to the computer before the show?
If you use Internet Explorer, please follow the methods.
Method 1:
If you see pop-ups suspicious, bars unwanted tools, redirects, strange results or other unexpected behavior on your computer, you may have been deceived by installing malicious software (also known as 'malware') on your computer. This behavior is known as the browser hijacking.
To correct your hijacked browser I suggest to follow the steps outlined in the article below and check if it helps to solve the problem:
http://www.Microsoft.com/security/spyware/browserhijacking.aspx
Method 2:
Step 1:
Start the computer in safe mode with network and perform antivirus analysis.
See the link.
http://Windows.Microsoft.com/en-us/Windows7/advanced-startup-options-including-safe-mode
Step 2:
Perform an online virus scan.
http://www.Microsoft.com/security/scanner/en-us/default.aspx
Note: the data files that are infected must be cleaned only by removing the file completely, which means there is a risk of data loss.
Method 3:
Follow the steps in the link.
Method 4:
optimize Internet Explorer and check.
NOTE: The Reset Internet Explorer Settings feature might reset security settings or privacy settings that you have added to the list of Trusted Sites. Reset the Internet Explorer settings can also reset parental control settings. We recommend that you note these sites before you use the reset Internet Explorer settings

Unable to connect to the host server: a connection attempt failed because
Hi all

My ESX server hosts have static IP addresses.
I've seen a few similar posts on this issue, but their solutions have not worked for me.
Best regards
Nathan
I think we confuse you. ESX server is running like a machine virtual within the workstation, correct? If Yes, then you must edit the vmx esx server with these entries monitor configuration file *. They can go anywhere in the file. Once those have been added, you should be able to run 32-bit virtual machines within the esx server.
