Recent Hacks: NBC.com, Twitter, and Zendesk – Warnings: Tumblr, Pinterest

cybercrime

After dealing with multiple attacks on several sites, including Apple, Facebook, and Twitter – this being Java exploits. Now, it’s time to deal with more hacks, including NBC.com (which has been serving up malware for a day now) and Twitter. As in recent reports now, Tumblr and Pinterest have been forewarned.

The latest high profile organization that was recently hacked is the National Broadcast Company (NBC), more specifically on their website. The idea from the hackers is to use the website to infect visitors, using exploits and other JavaScript injections.

NBC.com’s hacked pages were modified to include additional HTML component called IFRAME, which is inline frame. This allows at least a 1px x 1px frame to be included independently in the webpage, which may contain malicious code. In HTML code, frames can be made to host web content. But, in the hands of the evildoers, aka cybercriminals, it is used as an effort to launch malware campaigns.

Malicious JavaScript was added to the mix, and also used the exploit kit called RedKit. It delivers one of two exploit files to try to take control of your browser.

I recognized something was wrong with NBC.com, which may have already been hacked a few weeks ago, and I posted the information on my Twitter account that a downloaded file was sent to my browser asking me to save or open it. This was on a sister site/blog, RedTape. I asked people to replicate it. The Twitter status can be found here.

What type of malware was delivered? Citadel or ZeroAccess, which are both crimeware families and botnets. They are usually part of several exploit kits.

This drive-by download situation is no good, as the pages were taken offline. Therefore, that dropped the traffic of those specific areas of the site. It is sure that this situation is a matter of cybercrime aimed at a financial side of things, not defacement or pranks.

Was it a big deal that it was NBC? No. In fact, it is sure the hackers were aimed at using a high-profile site, and apparently NBC.com was the easiest or quickest to access. Hackers rely on time and many other factors to make their approach(es).

Zendesk hacks and other various warnings

Zendesk is all about customer support…therefore no one really knows, except for those in the business of customer support. Big names use this service, which include Tumblr, Twitter, and Pinterest, among others. Hackers broke into the Zendesk systems, accessing email addresses of those big name customers, namely Twitter, Tumblr, and Pinterest.

How “pinteresting” that another hack has been born, which is related to a social network. Zendesk detailed the hack:

We’ve become aware that a hacker accessed our system this week. 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.

The companies involved made a point to tell its customers that they haven’t been hacked, but private information was stolen. Luckily, no password thievery was involved.

Obviously, an incident like this, just like the NBC.com incident, needs to be taken very seriously. Something must be done to stop the continuous hacks.

Twitter hacks additionally are nothing new. Many times, hackers used a backdoor, such as the tools the support team uses, to infiltrate the information of Twitter users. It’s not a huge gain, more possibly a waste of time.

Zero-Day Java Exploit Affects Facebook

After all of the latest attacks on government, corporate, and social networking organizations, Twitter the most recent, it appears Facebook had their share this year.

Facebook revealed yesterday that it was hit in January from an unidentified group of hackers, however, no user information was compromised during the attack.

Here is a snippet from the note issued:

Last month, Facebook Security discovered that our systems had been targeted in a sophisticated attack. This attack occurred when a handful of employees visited a mobile developer website that was compromised. The compromised website hosted an exploit which then allowed malware to be installed on these employee laptops. The laptops were fully-patched and running up-to-date anti-virus software. As soon as we discovered the presence of the malware, we remediated all infected machines, informed law enforcement, and began a significant investigation that continues to this day.

It was said also that a zero-day Java exploit was found, when the suspicious domains in their logs revealed in the Java sandbox many vulnerabilities. The update was provided to Oracle who shipped patch(es) for the specific vulnerabilities found.

The company also stated, “We will continue to work with law enforcement and the other organizations and entities affected by this attack. It is in everyone’s interests for our industry to work together to prevent attacks such as these in the future.”

Other websites were additionally affected by this, and that the computers affected at Facebook were fully patched and clean before the attack.

FBI Report: Hacker Blackmailed over 350 Women to Strip on Webcam

cybercrime

The FBI has taken into custody a 27-year-old man, claiming that he hacked the accounts of Facebook users coaxing hundreds of women to strip on their webcams, while watching on Skype.

The man identified by the FBI as Karen (“Gary”) Kazaryan of Glendale, CA, was arrested yesterday on federal computer hacking charges.

According to a US Department of Justice press release, Kazaryan is claimed to have broken into victims’ Facebook and email accounts, changing their passwords, and searching for naked and half-naked photographs. He also gathered personally-identifiable information from the users, including passwords, personal details, names of friends, etc.

The report details also that Karen threatened the users who did not comply to his demands of stripping, that he would post nude photos of them on their own Facebook pages. It is also reported that approximately 3,000 photos were seized from the man’s computer. The FBI believes 350 women were lead in to “sextortion”.

The FBI is urging all women who believe they might be a victim to contact the Los Angeles Field Office at +1-(310) 477-6565.

Security Concerns This Winter – Android Malware, Facebook Problems, Anonymous, among other things

We’ve discussed over the past couple of weeks some of the things that happened in 2012, and things we’re focused on coming into the new year. There is a surge in a lot of security concern over several different issues, including Android malware, Anonymous, cyberwar, among other things. Here is a comprised list of the top concerns this Winter that we’ll be investigating on a continual basis.

  1. Identity Theft – this can be a problem for most people that get viruses and other malware on their computer. It can also be a problem on social networks. It is best to have a good antivirus and keep your social networking information safe. You don’t have to enter everything in your profile. Leave some fields blank so it is more trivial for the unsuspecting stalker. Sadly, you cannot know who’s viewed your profile, which makes it more difficult to discover stalkers. Hmm…hint Facebook.
  2. Spear-Phishing – plain and clear, spear-phishing is similar to identity theft. This is done by email-spoofing, which the attacker is masking him-or-herself as a legitimate company with legitimate looking emails. However, these emails are only subject to make you click and to either steal your information, or distribute malware, or even both. Normally, this is a big problem over the holidays, but now it’s starting to become widespread no matter the time of year.
  3. Human Error and the Failure to Update – Vulnerabilities – It is true that humans forget a lot of things. One of the biggest security risks we have always faced is that users fail to update their browser plugins and programs on their computer. However, through the use of this vulnerability, attackers exploit and send malware your way. Using a vulnerability scanner can help you keep managed of this atrocity.
  4. Browser Hijackers and Junkware – we still continue to see the problem of browser hijackers and junkware being distributed in installers for legitimate programs. What’s sad is, the royalties are so high for software developers to add in the install code for junkware, that the developers don’t know how bad the issue is. From Babylon Toolbar to Claro Search…these toolbars and homepage hijackers are unnecessary and technically need to be done away with. Good thing our security community has the ability to remove this crap with our special tools.
  5. Malware growth on Other Platforms – it’s no surprise that malware problems are lighting up on the iOS now, as well as Linux. It sure will start to become a problem this year. Even more on Windows 8 and Android than any other device.
  6. Android Malware Growth – This has become one of the biggest problems right now in the computing world is the steady high growth of malware on the Android platform. It will continue to be a problem, sadly.
  7. Anonymous Cyberattacks, and Government Cyberwar – we will still see cybercrime and cyberwar problems continue this year.

Video “OMG I just hate Rihanna…” Facebook scam spreading

Messages are spreading between Facebook users, claiming that members of the social network have lost all respect for popular songstress Rihanna after watching a video.

However, if you’re careless enough to click on the link you will find yourself lured into a survey scam that attempts to earn affiliate cash for fraudsters.

A typical message trying to tempt users into falling for the scam looks like this:

If you were fooled into participating in this scam remove the message from your newsfeed, and delete any messages you may have inadvertently shared with your friends. That way at least you are no longer spreading it with your online chums. You can also report the link as spam – hopefully if enough people do it, Facebook will begin to stop the scam from spreading.

Miley Cyrus sex tape scam details

Unbelievable? Another social engineering attempt. Here is a source on the non-existent Miley Cyrus sex tape:

Facebook scammers are using the promise of a non-existent Miley Cyrus sex tape to lure users into giving up temporary access to their accounts. Once inside, scammers run a script to create automatic posts that tag friends and propagate the scam.

Here, again, we are dealing with the well-known, if not utterly obsolete, “copy/paste code” method whereby the scammer aims to steal the victim’s Facebook authentication token. This grants the scammer temporary access to the targeted Facebook account, including the victim’s list of friends.[HOTforSecurity]
