25 Most-Used Passwords Revealed

PasswqordsRachel King at ZDNet’s Zero Day writes that the recent data breaches at LinkedIn, Last.fm and eHarmony has put passwords back in the spotlight. Unfortunately many people still rely on “password” to secure their digital identity. Antivirus software provider ESET noted some recent work by IT security consultant Mark Burnett who has compiled a list of the “top 500 worst (aka most common) passwords” based on a variety of methods he has detailed on his blog. The entire list is available here (ZIP).

Paper Based Data Breaches Growing

Brian Krebs at the Washington Post’s Security Fix points out that paper-based data breaches on the rise. Krebs cites statistics for the Identity Theft Resource Center , a San Diego based nonprofit which says at least 27 percent of the data breaches disclosed publicly in 2009 stemmed from collections of sensitive consumer information printed on paper that were lost, stolen, inadvertently distributed or improperly disposed of.

The ITRC has logged 125 paper breaches of the 463 incidents  they recorded in 2009. These breaches were across all sectors, with businesses having the most followed by the government sector.

“Computers were supposed to take us to a paperless society, yet computers probably create more paper than before we had them, because now we want a hard copy as well as what’s on the computer,” ITRC co-founder Linda Foley told Security Fix. “It’s a double danger of course, because paper – especially when it’s just tossed in a dumpster somewhere – is not like data on a hard drive. It’s ready to use, it often contains the consumer’s handwriting and signatures, which can be very useful when you’re talking about forging credit card and mortgage applications.”

Stuart Ingis, a partner with the law firm Venable LLP in Washington, told Security Fix that many clients he deals with strictly speaking do not have a legal obligation to report paper-based breaches, but that most of his clients err on the side of caution.

Experts say that paper data breach  incidents come to light in large part due to a proliferation of state data breach notification laws. Some 45 states and the District of Columbia have enacted laws requiring companies that lose control over sensitive consumer data such as Social Security or bank account numbers to alert affected consumers, and in some cases state authorities. Concerned about the mounting costs of complying with so many different state breach regulations, businesses often find it easier and cheaper to adhere to the strictest state laws. The current federal data breach notification proposals will preempt state measures and will allow paper-based breaches to go unreported because they would require notification only when data stored electronically is lost or stolen and are largely silent on paper breaches. Only Massachusetts and North Carolina currently require notification whether the data breached is in electronic or paper form.

When we talk to clients about information security and not just information technology security, we ask them to consider that lost paper documents are just as damaging to a company’s reputation should they get into the wrong hands as electronic data stored in an Excel spreadsheet or database server? But data on paper is just another form of data that needs to be protected by information security policies.

Lessons From A Mega-Breach

securityUpdated 04-05-09Wired is reporting that on August 28, 2009 accused hacker, Albert Gonzalez accepted a plea agreement with federal prosecutors in Boston.   According to report’s Gonzalez has agreed to plead guilty to all of the charges in a 19-count indictment and will face a sentence of 15 to 25 years. He’s also agreed to forfeit nearly $3 million in cash as well as a Miami condo, a BMW car, a Tiffany diamond ring and three Rolex watches that he gave to others as gifts, a Glock 27 firearm seized from him at the time of his arrest and a 350C currency counter, among other items.

The agreement resolves the case against Gonzalez in Massachusetts — which charged him with hacking into TJX, Barnes & Noble and OfficeMax — as well as a case in the eastern district of New York that charged him with hacking into the Dave & Busters restaurant change. Still outstanding are charges  alleging that Gonzalez also hacked into Heartland Payment Systems, Hannaford Brothers, ATMs stationed in 7-11 stores, and two unnamed national retailers.

Gonzalez is scheduled to officially enter his plea at a court hearing on September 11. His lawyer, Rene Palomino, did not return calls seeking comment from the New York Times.

Updated 08-30-09 – On 08-24-09 The Financial Times reported that  Gonzelaz and crew penetrated a network linking 2,200 Citibank-branded ATMs kiosks inside 7-Eleven stores from late 2007 through to at least February 2008. The ATMs displayed Citibank’s logo. The network and the machines were owned by Texas-based CardTronics, which took in monthly fees from Citi. Reportedly the group  lifted card and PIN codes from the system, and their allies manufactured new cards that were used to get about $2m in cash from Citibank ATMs elsewhere. An FBI affidavit said Yuriy Ryabinin of Brooklyn withdrew $750,000 from Citibank accounts in February 2008.

The U.S. Department of Justice, handed down an indictment in the  Heartland Payment Services data theft on August 17, 2009.  The Heartland, data breach is the largest data theft on record in the U.S.. The Feds allege that beginning in October 2006, 28-year-old Albert Gonzalez, aka “segvec,” “soupnazi,” and “j4guar17,” of Miami, FL, and his unnamed co-conspirators, in Russia and Virginia. executed the Heartland data breach. This attack led to the theft of over 130 million credit and debit cards accounts.  Gonzales faces two counts of conspiracy and conspiracy to engage in wire fraud.

In addition to stealing credit and debit card data from New Jersey based Heartland Payment Systems; the conspirators also targeted 7-Eleven Inc., and Hannaford Brothers, a supermarket chain based in Maine, along with two other major national retailers whose names were withheld. According to the Government, planning for the attacks began in 2006. The indictment says that in October of 2006, Gonzalez and his co-conspirators began to search for potential corporate victims by gathering intelligence such as the credit and debit card systems used by their targets. In August 2007, 7-Eleven was hit with a SQL injection attack which resulted in an undetermined number of accounts being compromised. In November 2007, Hannaford reportedly detected a Trojan designed to skim magnetic stripe information from the checkout stations. This attack compromised 4.2 million accounts.  Beginning on or about Dec. 26, 2007 , Heartland was hit with a SQL injection attack on its corporate network that resulted in malware being placed on its payment processing system and the theft of more than 130 million credit and debit card numbers and corresponding card data.

According to the indictment, Gonzalez and his cohorts exploited vulnerabilities that are typically  in many cybercrime cases. SQL injection attacks were used to insert specially crafted malware designed to evade detection. Once inside the corporate networks, the attackers used sniffers to conducted reconnaissance, find and steal credit and debit card numbers and other information. According to the DOJ , the group tested their malware by putting it up against approximately 20 different anti-virus programs. The group used computers in California, Illinois, Latvia, the Netherlands and Ukraine to stage attacks and store malware and stolen information.

While the attacks appear to be phased-in and coordinated, the attackers used classic and well-known methods that could have been defended against, experts say.  Robert Graham, CEO of Errata Security told Dark Reading that the attacks outlined in the indictment basically provide a roadmap for how most breaches occur, “This is how cybercrime is done,” Graham says. “If there is a successful attack against your company, this is roughly what the hackers will have done. Thus, this should serve as a blueprint for your cyber defenses.”

In a Dark Reading article, Rich Mogull, founder of Securosis , says the attacks were preventable, mainly because they employed common hacking techniques that can be foiled.  He points out that  the attacks appear to mimic those in a an advisory issued by the FBI and Secret Service that warned of attacks on the financial services and online retail industry that targeted Microsoft’s SQL Server. The advisory included ways to protect against such attacks, including disabling SQL stored procedure calls. “This seems to be a roadmap” to these breaches, Mogull says. “The indictment tracks very closely to the nature of attacks in that notice.”

“The attack took planning and organization, but ultimately it was done with relatively common attack techniques,” said Rohit Dhamankar, director of DVLabs at TippingPoint in an eWeek article, “It just goes to show that even the most basic type of attack can do serious damage and enterprises need to be more vigilant about protecting the outward facing portions of their networks.”

Rick Howard, intelligence director for iDefense, told Dark Reading that enterprises still aren’t closing known holes in their networks and applications. “They were using the same stuff that works all the time,” he says. “And it’s [an example of] another organization not diligent in closing up [vulnerabilities] we know about.”

Prevention

Upesh Patel, vice president of business development at Guardium, told Dark Reading the attackers must have exploited applications with authenticated connections to the database. “Since a SQL Injection attack exploits vulnerabilities in the database, the attack could have occurred from any end-user application that was accessing the database.”

Errata’s Graham says the initial attack vector, SQL injection, is often dismissed by enterprises as unimportant. “We always find lots of SQL injection [flaws] with our clients. We talk to them about it, but get push-back from management and developers who claim SQL injection is just a theoretical risk.”

As a fix, Graham recommends, ”The simple solution is to force developers to either use ‘parameterized’ queries or ‘sanitize’ input.” He also suggests that SQL-based servers be hardened. “Once they got control of the database, they were able to escalate the attack to install malware on the systems. The simple solution is to remove all features of the database that aren’t needed,” he says, such as “xp_cmdshell,” which attackers commonly abuse. Graham goes on to suggest that anti-virus doesn’t catch custom malware like the attackers wrote for their attacks, so add policies and technologies that can spot unknown threats.

Gonzalez crews’ alleged use of their own sniffers that copied card data from the network could have been thwarted with encryption according to Richard Wang, Sophos Labs‘ U.S. manager. Wang tells InternetNews that the data should have been encrypted while in transit on the wire.

Sopho’s Wang says that the databses be secured,  “Businesses should secure the application code, and make sure that the underlying server and operating system are up to date with the latest patches.” Securosis’ Mogull says  not to use a privileged account for the relational database management system. In a blog post, Mogull says to deploy data leakage protection to see if you can detect any card data internally before the bad guys find it, and l to focus on egress filtering.

“This was preventable,” Securosis’ Mogull says of the major breaches. “There was some degree of sophistication — like they knew HSMs — but definitely the main way they got in is not the most sophisticated.”

Gonzalez, who is in federal custody, faces a maximum sentence of 20 years in prison on wire fraud conspiracy, and another five years on conspiracy, plus $250,000 for each of the charges.  In May 2008, the U.S. Attorney’s Office for the Eastern District of New York charged Gonzalez with an alleged role in the hacking of a computer network run of  restaurant chain Dave & Buster’s. The trial on those charges is scheduled to begin in Long Island, N.Y., in September.

In August of 2008, the Department of Justice announced more indictments against Gonzalez and others for a number of retail hacks affecting eight major retailers and involving the theft of data related to 40 million credit cards. Those charges were filed in the District of Massachusetts. Gonzalez is scheduled for trial on those charges in 2010.

The work we do on behalf of our clients frequently includes many of the steps highlighted in this incident. We always insist that vendors harden any servers brought on to a clients site and that un-necessary services be removed. Before we recommend the Owner accept any installation, the vendor has to fully patch the OS and any applications provided. More recently we have started to include internal and external facing port scans.

Indictments Arrive for Largest U.S. Credit Card Breach

Heartland Payment Systems Reports Breac

TJX Hacker Charged With Heartland, Hannaford Breaches

Fannie Mae – What Ails America

ComputerWorld reports that an Indian national Rajendrasinh Babubhai Makwana, in a contract position as a Unix engineer for the Federal National Mortgage Association, better known as Fannie Mae , has been accused of planting malicious code on the corporation’s network that was to “destroy and alter” all of the data on the company’s servers on 01-31-09, court documents show.

Makwana, 35, was indicted on 01-27-2009 by a federal court on a single charge of computer intrusion, according to documents released yesterday. Reports are unclear about the attackers employer or his employment status. According to the AP,  Makwana  has lived in the United States since at least 2001.

According to the complaint sworn by FBI Special Agent Jessica Nye, Makwana was let go from his contract position at Fannie Mae’s Urbana, Md., data center on Oct. 24, 2008, after he had “erroneously created a computer script that changed the settings on the Unix servers without the proper authority of his supervisor,” Makwana had created that settings-changing script on Oct. 10 or Oct. 11, as much as two weeks before he was fired, Nye said.

Within 90 minutes of being told he was terminated on Oct. 24, and several hours before his access to the Fannie Mae network was disabled later that evening, Makwana embedded a malicious script in a legitimate script that ran on Fannie Mae’s network every morning, Nye said in her affidavit.

The logic bomb would have “caused millions of dollars in damage and reduced if not shutdown [sic] operations at [Fannie Mae] for at least one week” if it had not been found before Saturday’s trigger date, the complaint said. “this script would power off all servers, disabling the ability to remotely turn on a server,” said the government’s complaint. “Subsequently, the only way to turn the servers back on was physically getting to a data center.”

I agree with Dvorak’s piece on MarketWatch which asks the rhetorical question, why was Makwana working at Fannie Mae in the first place?  Are you telling me no American citizen could have done his job?  It has long been believed that in most cases H-1B visas in technology have been exploited by companies such as Fannie Mae only because programmers coming from India work cheaper. Over the years, companies like Fannie Mae have been begging for more and more H-1B visas. That means more people working cheaper than the going rate. You get what you pay for.

This episode also is further evidence that Fannie Mae is still a poorly run company. Is it really so hard to turn-off someones network access when you take their ID card?. A good place to start is that when a person is meeting with their boss and HR, to be terminated, their access to all systems is to be suspended. There is no reason to allow access to remote systems. In this case, based on the papers filed, Just more of my tax dollars at waste work.
