An online service that enables users to store and sync all kinds of data across multiple devices, Evernote, suffered an attack.

Attackers compromised user information, including email addresses and hashed passwords, Evernote officials said.

Evernote officials said they did not think the attackers were able to gain access to any of the data that users store on the service. However, the company said it was requiring that all users change their passwords immediately.

“In our security investigation, we have found no evidence that any of the content you store in Evernote was accessed, changed or lost. We also have no evidence that any payment information for Evernote Premium or Evernote Business customers was accessed,” Dave Engberg, the Evernote CTO, said in a blog post.

“The investigation has shown, however, that the individual(s) responsible were able to gain access to Evernote user information, which includes usernames, email addresses associated with Evernote accounts and encrypted passwords. Even though this information was accessed, the passwords stored by Evernote are protected by one-way encryption.”

Although the company does not say what hash algorithm it uses to protect passwords, it uses 64-bit RC2 to encrypt data within users’ notes.

“For Evernote’s consumer product, the current encryption algorithms are chosen more for exportability under the Commerce Department rather than strength, since our software permits the encryption of arbitrary user data with no escrow,” Evernote said.

Evernote users have the ability to store just about any kind of data on the service, including text, video and other information. Users can encrypt data within specific notes, and the company doesn’t have a copy of users’ keys, so if the passphrase if lost or compromised, there’s no way for the company to recover that data.

Evernote sent all of its users an email detailing the incident and informing them they need to change their passwords before logging in the next time.

Two fairly big hacks occurred last week as NBC.com and customer service software provider Zendesk were victims of separate attacks.

“We’ve become aware that a hacker accessed our system this week,” said Zendesk Chief Executive Mikkel Svane on the company blog. “As soon as we learned of the attack, we patched the vulnerability and closed the access that the hacker had.”

“Our ongoing investigation indicates that the hacker had access to the support information that three of our customers store on our system. We believe that the hacker downloaded email addresses of users who contacted those three customers for support, as well as support email subject lines. We notified our affected customers immediately and are working with them to assist in their response.”

He didn’t name the three customers.

Meanwhile, the website of NBC.com, suffered a hack job and the computers of visitors to the site ended up infected with malware. An NBC spokeswoman confirmed the incident. According to researchers, a hacker had gained access to the site and then embedded malicious iFrames into the pages. On unprotected systems, a variant of the Citadel Trojan, used for banking fraud and espionage, the malware would then end up installed.

The NBC spokeswoman said the site is now free and clear and user information suffered a compromise and that “users who go on there now are safe.”

Technology is vital and so are policies and procedures, but the true backbone behind a solid cyber security profile is the people making sure everything is running as scheduled.

“People are the most important factor in security,” said Paul Forney, chief technologist at Invensys’ R&D security team during Invensys Operations Management’s User Group Series in Anaheim, CA, Thursday. “It takes people. If you don’t change the culture; it is the most important thing. You have policies and procedures; you have technology, but you need the people.”

There are three pillars to ensure true cyber security and they all carry a percentage of importance, Forney said. They are people at 65 percent, policies and procedures at 15 percent and technology at 20 percent.

“It is all about the ROI all wrapped around operational excellence,” Forney said. “Somebody can come in and hack you; it is all about operational excellence. There are some smart hackers out there and if there is one little hole in a firewall, they will find it and exploit it. You can’t put in a solution and then walk away. Security is something you start and keep going. ”

Even in today’s environment where a new attack is just around the corner, there are some organizations that just don’t want to move forward with a comprehensive security program.

“Industrial environments are dangerous; there is some powerful stuff that can happen at a plant,” Forney said. “People say they are air gapped, but 99.9 percent of control systems are connected to the business system, which is connected to the Internet.”

An attacker, he said, has three challenges:
• Gain access to the control system LAN
• Through discovery, gain understanding of the process
• Gain control of the process

Obviously, the security professional’s goal is to hold the attackers at bay and ensure the system stays up and running. But the attack vectors are ever increasing with so many potential types of assaults.

Cyber warfare is just one newer attack, with individual countries firing cyber shots across each others’ bows.

“We now have the Army, Air Force, Navy and Cyber Ninjas,” Forney said.

In addition to cyber warfare, there are plenty of threats out there facing manufacturers from terrorism, disgruntled employees, to extortion and stealing private company assets.

While those issues are very similar to the woes IT professionals deal with on the business enterprise, those looking over the industrial control systems (ICS) need to keep a sharp eye out because the consequences can be much greater.

“We are exposed to the same issues IT has, but we do have different needs,” Forney said. “We don’t use all of IT’s best practices because we do have different needs, like our end points are machines. In the IT world, if there is a problem you lose something on your hard drive. In ICS, you have people hurt. Security has to have specialized equipment, but it can’t slow down the process.”

Forney then showed some objectives security professionals should watch for:
• Prevent unauthorized changes to values in a controller, PLC
• Prevent misrepresentation of process values on the HMI
• Reduce the possibility of a production slowdown due to ICS software
• Protect integrity of process
• Prevent loss of genealogy
• Provide availability and safety

One of the most important things — if not the most important — a security professional should do is to clamp down the network and understand what programs you should run and then turn off everything else, Forney said. No unnecessary programs.

He then added some best ICS practices:
• Maintain the latest patches
• Test every patch
• Always use current antivirus definitions
• Verify update was successfully installed
• Update authorized application software
• Enable network antivirus intrusion protection system
• Enable system policies on all capable network appliances

One other item is to not use or limit the usage of USB devices, unless they have undergone a scanning process that ensures they are virus free. Also, designate a specific machine to use the USB device.

“You should know about everything on your network,” Forney said.

Sony seems to have fallen into the grips of a group of hackers as they said they took control of eight Sony servers because of the firm’s lax security.

The group called Null Crew made the claim on Twitter and via a Pastebin release.

The release shows a list of usernames and passwords that apparently relate to Sonymobile.com, and a message to Sony that accuses the firm of not having strong enough security credentials. This is not the first time that Sony suffered a hack attack.

“Sony, we are dearly dissapointed in your security. This is just one of eight sony servers that we hve control of. Maybe, just maybe considering IP addresses are available,” said a message posted to Pastebin.

“Maybe, just maybe it’s the fact that not even your customers can trust you. Or maybe, just maybe the fact that you can not do anything correct technologically.”

A heavy hack attack earlier saw 77 million users’ details exposed and lead to Sony shutting down a range of its networks.

Null Crew said it had access to a range of other websites too, and on Twitter said it had attacked Cambodian government websites in retaliation over the arrest of one of The Pirate Bay’s cofounders.

Blizzard’s internal network suffered a breach, but the “unauthorized and illegal access” is now closed off, and an investigation started.

While Blizzard is not a manufacturing automation company, it is just another example of attackers targeting a specific company and then getting into a system and attempting to garner as much information as possible. This time, it seems the company was able to catch the foes before losing too much data.

“Some data was illegally accessed, including a list of email addresses for global Battle.net users, outside of China,” said Blizzard’s Chief Executive Mike Morhaime. “For players on North American servers (which generally includes players from North America, Latin America, Australia, New Zealand, and Southeast Asia) the answer to the personal security question, and information relating to Mobile and Dial-In Authenticators were also accessed. Based on what we currently know, this information alone is NOT enough for anyone to gain access to Battle.net accounts.”

Cryptographically scrambled versions of Battle.net passwords for players on North American servers also ended up stolen, so players should change their password.

They will also get a prompt to change their secret questions and answers, as well as to update the software for the Battle.net authentication if they use one.

Nissan Motor Co.’s information systems suffered from a hack attack.

So far, the company doesn’t know who the hackers were, or where they struck from and it’s unclear what data suffered a compromise.

Nissan believes the hackers were looking for intellectual property related to its EV drivetrains.

Nissan maintains it quickly secured its system and issued a statement alerting customers and employees its data systems suffered a breach. Nissan said they discovered the infiltration April 13.

Nissan issued a statement, saying:

“We have detected an intrusion into our company’s global information systems network.

“On April 13, 2012, our information security team confirmed the presence of a computer virus on our network and immediately took aggressive actions to protect the company’s systems and data. This included actions to protect information related to customers, employees and other partners worldwide. This incident initially involved the malicious placement of malware within our IS network, which then allowed transfer from a data store, housing employee user account credentials.

“As a result of our swift and deliberate actions we believe that our systems are secure and that no customer, employee or program data has been compromised. However, we believe that user IDs and hashed passwords were transmitted. We have no indication that any personal information and emails have been compromised. Regardless, we are continuing to take appropriate precautionary measures.

“Due to the ever-evolving sophistication and tenacity of hackers targeting corporations and governments on a daily basis, we continue to vigilantly maintain our protection and detection systems and related countermeasures to keep ahead of emerging threats. Our focus remains on safeguarding the integrity of employee, consumer and corporate information.”

Nissan said it opted to keep the hack secret for the last 10 days until it had a better idea what was going on, a spokesman said.

First Chrome was a victim, and then the hackers went on to Internet Explorer.

That is what happened with a team of vulnerability researchers from French firm VUPEN hacked into Microsoft’s Internet Explorer 9 on a fully patched Windows 7 SP1 machine at the CanSecWest security conference in Vancouver. VUPEN researchers were also responsible for taking down the Google Chrome browser.

They managed to bypass the browser’s DEP and ASLR protection with a zero day heap overflow vulnerability, and then used a separate memory corruption bug to break out of its Protected Mode, which is effectively a sandbox.

Those particular flaws have existed in previous incarnations of the browser — all the way back to IE 6 — and will very likely work on the upcoming IE 10, said VUPEN founder Chaouki Bekrar.

He said it took two of their researchers six weeks of full-time work to develop an exploit for the browser. “When you have to combine many vulnerabilities and bypass all these protections, it takes a longer time,” he said.

He also said the memory corruption bug they used is only one of the many vulnerabilities they found that can break out of IE’s Protected Mode. He did say, though, the new IE 10 will be much harder to break into, as Microsoft has added new protection mechanisms.

Microsoft will get its hands only on the information regarding the heap overflow bug. “We will keep the Protected Mode bypass private for our customers,” Bekrar said.

It has been known embedded web servers are an easy mark when it comes to being able to hack into them.

That knowledge has existed for quite a few years. With that knowledge it may be easy to assume companies would move to protect their systems. Wrong.

Embedded web servers (EWS) are just as easy to access now than they were years ago. With multi-function printers or video conferencing systems, there can be serious data leaks: Printers store scanned, faxed and printed files on hard disks and then disclose these often sensitive documents. Video conferencing hardware allows outsiders to monitor rooms remotely or listen to meetings that are in progress, said Zscaler’s Michael Sutton at the RSA Conference in San Francisco.

Sutton wanted to scan a million web servers and create a catalogue of all the embedded web servers he found. His first tests involved Nmap and the Google Hacking Database (GHDB). However, neither tool proved very successful, as Nmap doesn’t detect enough EWS fingerprints and will, therefore, produce useless device information. Google, on the other hand, doesn’t allow search queries via scripts and would have required time-consuming manual scans.

The security researcher ended up using the Shodan online scanner. Sutton said Shodan has a huge database containing the HTTP header information of EWS systems, allowing such devices to undergo identification with accuracy. The researcher entered typical character strings from the embedded web servers’ web pages into Shodan. To automate the process, Sutton used a Perl script that only sent HEAD queries via Shodan. The script hosted on several EC2 micro instances in Amazon’s cloud which, according to the researcher, only cost a few dollars.

The scan managed to examine the targeted one million web servers in a short time and came up with the following results: Thousands of multi-function devices (more than 3,000 devices by Canon, 1,200 Xerox photocopiers, 20,000 Ricoh devices, among others), 8,000 Cisco IOS devices and almost 10,000 VoIP systems and phones didn’t require any log-in authentication. The latter included 1,100 devices by the German manufacturer Snom. These devices include packet tapping features and PCAP tracing by default. Imported into Wireshark, the trace can convert into a sound file of the telephone conversation.

The majority of the detected devices did not enjoy password protection, Sutton said. This means that any web user can access their web interfaces through a browser and view the documents stored on such photocopiers and printers, forward incoming faxes to an external number, or record scan jobs. With HP devices, a script can carry out such intrusions that every second calls a URL whose only variable is UNIX epoch time, which is easy to figure out.

The scan run by Sutton also identified more than 9,000 video conferencing systems by Polycom and Tandberg (now Cisco). The most likely reason why these devices were openly accessible on the net is they all use the H.323 protocol and require numerous open ports in the firewall. Sutton thinks administrators shy away from this, placing their systems in a DMZ instead. The IT security expert used a video to demonstrate how he managed to monitor the targeted conference rooms via an accessible video conferencing system that provided sound and images.

Sutton’s company is now providing the brEWS scanner free of charge, which specializes in detecting embedded web servers. To avoid placing the weapon into the hands of criminals, scans can only be run in a /24 subnet. At a later stage, the researcher also plans to offer a browser add-on that will allow administrators to examine protected internal networks; this add-on will carry out the scan and then send the results to the brEWS server for identification.

More than 85 percent of the data breach incident response cases investigated by Verizon Business last year originated from a hack, and more than 90 percent of them came from the outside rather than via a malicious insider or business partner, a new study said.

Those facts are just one snapshot of data from Verizon’s upcoming 2012 Data Breach Investigations Report, using data from its own caseload of 90 of its 855 breach cases.

“This is the first year that we worked more cases outside the U.S. than inside. That ratio has been building and it makes the case that this is not a U.S.-specific problem. All regions are having data breaches,” said Wade Baker, director of research and intelligence at Verizon Enterprise Solutions.

At the top of the list of compromised industries again was retail, financial services, and hospitality. And a big factor in this year’s cases was the rise in hacktivist-based attacks, Baker said.

Outside or external attackers jumped from 88 percent in 2010 to 92 percent in 2011, and breaches due to internal threats continued to decline, from just more than 10 percent in 2010 to less than 5 percent in 2011, according to Verizon’s data. “We can expect this trend to continue. Every single caseload we ever looked at shows the external [threat agent] as the majority except for one,” Baker said.

As for breach methods, hacking (86 percent) and malware (57 percent) were on the rise, while social engineering, misuse, physical threats, errors, and environmental factors all dropped.

The most commonly used venue for breaches was exploiting default or easily guessed passwords, with 29 percent of the cases last year, followed by backdoor malware (26 percent), use of stolen credentials (24 percent), exploiting backdoor or command and control channels (23 percent), and keyloggers and spyware (18 percent). SQL injection attacks accounted for 13 percent of the breaches.

“There were a lot of authentication-type attacks,” Baker said.

As for the targets, 90 percent of the breaches Verizon investigated went after servers, mainly point-of-sale servers, Web and app servers, and database servers. Nearly 50 percent targeted user devices such as desktops, laptops, and POS terminals. “The user device serves as a foothold into the environment. They are trying to get into your environment and then they spread out,” Baker said.

How do organizations learn they suffered a hit? Most find out from an external source, usually law enforcement, Baker said. And for nearly 60 percent of the cases, it took months before the organization learned it suffered a hack.
