1242 Million Facebook Accounts tweets Million Facebook Accounts 04/23/10 by Jolie O’Dell A hacker who calls himself Kirllos has obtained and is now offering to sell 1.5 million Facebook IDs at astonishingly low prices — $25 per 1000 IDs for users with fewer than 10 friends and $45 per 1000 IDs for users with more than 10 friends — according to researchers at VeriSign’s iDefense. Looking at the numbers, Kirllos has stolen the IDs of one out of every 300 Facebook users. Information for sale includes login credentials; whether or not the e-mail addresses and passwords are legitimate is currently unknown.

Typically, this information would be sold for between $1 and $20 per account, according to data from Symantec. Currently, around 700,000 accounts have been sold. The threads where the accounts are being sold have been removed, as far as we are able to tell. The users whose e-mail addresses and passwords have been compromised risk having their identities stolen, but they could also become targets of more insidious scams.

As always, we will keep you updated about any Facebook scams that come across our news desk. Hacking Facebook isn’t a new hobby for this person. Here’s a screenshot of another offer the hacker previously made on a forum earlier this year; then, he was then selling 100,000 hacked accounts from users around the world: Kirllos also appears to have had an interest in iPhone applications at one point. According to some Antichat.ru forum users, he was born in Russia, lives in New Zealand, is 24 years old and speaks both English and French.

Network Solutions Hack Compromises 573,000 Credit, Debit Accounts

Anyone that had an online store hosted by Network Solutions needs to read this article.

Network Solutions Hack Compromises 573,000 Credit, Debit Accounts

Hackers have broken into Web servers owned by domain registrar and hosting provider Network Solutions, planting rogue code that resulted in the compromise of more than 573,000 debit and credit card accounts over the past three months, Security Fix has learned.

Herndon, Va. based Network Solutions discovered in early June that attackers had hacked into Web servers the company uses to provide e-commerce services – a package that includes everything from Web hosting to payment processing — to at least 4,343 customers, mostly mom-and-pop online stores. The malicious code left behind by the attackers allowed them to intercept personal and financial information for customers who purchased from those stores, Network Solutions spokeswoman Susan Wade said.

Wade said the company is working with federal law enforcement and a commercial data breach forensics team to determine the cause and source of the break-in. The payment data stolen was captured from transactions made between March 12, 2009 and June 8, 2009.

On Friday, Network Solutions began notifying affected customers by e-mail and postal mail. Due to the potential high cost of notifying individual victims, the hosting company is offering to handle the notification of affected customers of the breached online stores. Forty-five states and the District of Columbia have enacted laws requiring organizations to notify consumers when a data breach or loss jeopardizes the security of personal and financial data, but the rules for complying with those laws differ from state to state.

“We feel terribly about it to burden them with the notification process, which can be kind of tricky because there is no one federal data breach statute,” Wade said.

Critical JavaScript vulnerability in Firefox 3.5

Microsoft Internet Explorer has long been criticized as ‘insecure’ and vulnerable to attack while Mozilla Firefox was touted as the browser to use to keep your web browsing and your computer safe. It doesn’t appear that this is the case any longer. Make sure you apply all available patches as soon as they become available–for all your software–to keep your computer secure and less vulnerable to attack.

07.14.09 – 10:15am

Issue

A bug discovered last week in Firefox 3.5’s Just-in-time (JIT) JavaScript compiler was disclosed publicly yesterday. It is a critical vulnerability that can be used to execute malicious code.

Impact

The vulnerability can be exploited by an attacker who tricks a victim into viewing a malicious Web page containing the exploit code. The vulnerability can be mitigated by disabling the JIT in the JavaScript engine. To do so:

  1. Enter about:config in the browser’s location bar.
  2. Type jit in the Filter box at the top of the config editor.
  3. Double-click the line containing javascript.options.jit.content setting the value to false.

Note that disabling the JIT will result in decreased JavaScript performance and is only recommended as a temporary security measure.  Once users have been received the security update containing the fix for this issue, they should restore the JIT setting to true by:

  1. Enter about:config in the browser’s location bar.
  2. Type jit in the Filter box at the top of the config editor.
  3. Double-click the line containing javascript.options.jit.content setting the value to true.

Alternatively, users can disable the JIT by running Firefox in Safe Mode.  Windows users can do so by selecting Mozilla Firefox (Safe Mode) from the Mozilla Firefox folder.

Conficker Worm Targets Microsoft Windows Systems

Original release date: March 29, 2009
Source: US-CERT

Systems Affected

  • Microsoft Windows

Overview

US-CERT is aware of public reports indicating a widespread infection of the Conficker worm, which can infect a Microsoft Windows system from a thumb drive, a network share, or directly across a network if the host is not patched with MS08-067.

I. Description

The presence of a Conficker infection may be detected if a user is unable to surf to the following web sites:

If a user is unable to reach either of these web sites, a Conficker infection may be indicated (the most current variant of Conficker interferes with queries for these sites, preventing a user from visiting them).  If a Conficker infection is suspected, the infected system should be removed from the network. Major anti-virus vendors and Microsoft have released several free tools that can verify the presence of a Conficker infection and remove the worm. Instructions for manually removing a Conficker infection from a system have been published by Microsoft in http://support.microsoft.com/kb/962007.

II. Impact

A remote, unauthenticated attacker could execute arbitrary code on a vulnerable system.

III. Solution

DotNetNuke 5.0.0 Upgrade Warning

We have been supporters of DotNetNuke (DNN) for the past several years and offer it as a hosting option to our clients. For those not familiar with DNN, it is the Open Source ASP.NET answer to Joomla!–both being content management systems. A content management system is software that keeps track of every piece of content on your Web site, much like your local public library keeps track of books and stores them. Content can be simple text, photos, music, video, documents, or just about anything you can think of. A major advantage of using a CMS is that it requires almost no technical skill or knowledge to manage. Since the CMS manages all your content, you don’t have to.

Recently, DotNetNuke released to market (TRM) their newest version 5.0.0, and we upgraded immediately and were met with a multitude of problems–from images not showing up, users not being able to logon to their portals, and a whole host of other little issues. After visiting the DNN site forums, it turns out that we were not the only users experiencing these problems. There were some ‘fixes’ for some, but further reading found some of the developers suggesting restoring the previous version as there were a lot of problems that somehow escaped detection in the preliminary testing before the release. Additionally, they promised that there would be a version 5.0.1 that would ‘fix’ all of these issues coming out in short order. We restored our previous version of DNN and anxiously awaited the 5.0.1 version to be releases.
