Airport VPN hacked using Citadel malware
It sounds like an air traveler’s nightmare, Researchers at Trusteer
recently uncovered a variant of the Citadel Trojan targeting the virtual
private network (VPN) credentials used by employees at a major
airport.The firm would not disclose the name of the airport because the
situation is being investigated by law enforcement.
Many businesses use VPNs to provide outside workers with access to secure data. Incursions on these networks often involve advanced “Man in the Browser” malware such as the Citadel, Zeus, and SpyEye programs. The man-in-the-browser (MITB) assault first used form-grabbing malware, which steals data entered into web forms before it is passed over the internet, to steal the airport employees' VPN usernames and passwords, Amit Klein, Trusteer's chief technology officer, said in a blog post.
“This was potentially very dangerous, but we don’t know whether the attacker group was targeting the financial system of the airport for economic gain or if the attack was terrorism-related,”
The airport VPN was immediately disconnected after officials there were made aware of the breach and authorities are investigating.
The product that the airport was using to provide strong authentication for employees gave each user two choices: log in with a username and a one-time password that's sent via SMS or a smartphone app; or log in using a CAPTCHA-like image of 10 digits that the user maps to his own static password. The Citadel malware used the screen-capture tactic to defeat this.
"This security measure prevents the form grabber from capturing the actual static password. This is where the screen capturing feature in Citadel kicks in," Klein said.
Trusteer doesn't know who the attackers are and what they are after, but Kedem says they could be trying to gather intelligence on airport security processes, or even the border customs service.He says the attack appears to be very targeted, and the bottom line is that VPN connections are not safe.
In addition to using endpoint cybercrime prevention software, Kedem also advises users to abide by standard practices for preventing infection: avoid opening unknown attachments or clicking links in emails.

Google engineers Warn Of Serious Unpatched Adobe Reader Flaws
Adobe has missed dozens of vulnerabilities in Reader in this week’s
Patch Tuesday run according to Google engineers who reported the flaws.
Sixteen vulnerabilities still affected the Windows and Mac OS X
versions, while 31 critical and “trivially exploitable” bugs were found
in the Linux application.
Of particular concern to Google’s Mateusz Jurczyk and Gynvael Coldwind are bugs in Reader for Linux, although other issues affect versions for Windows and OS X. For the Linux version, which went completely unpatched, Adobe and Google have been working together to counter 14 “new unique crashes” and nine “test-cases” that were potentially exploitable for remote code execution.
When Adobe released a new version of Reader for Windows and Mac OS X earlier this week, it patched 12 vulnerabilities, but another 16 remained unpatched. Jurczyk and Coldwind decided to come forward with information on those flaws in the interest of user safety, as Adobe has no plans to issue additional out of band updates before 27 August.
“Considering that fixing the first twenty four crashes took twelve unique code fixes, it is expected that the remaining crashes might represent around eight more unique problems. Adobe plans to fix these remaining bugs and issue an update for the Linux version of Reader in an upcoming release,” the Google researchers said.
Adobe released new versions of Adobe Acrobat, Reader, Shockwave, and Flash to patch security holes in those products as well.
Check out the details of the Microsoft and Adobe security bulletins to figure out which ones apply to you, and prioritize the patches that are most critical or have the greatest potential to impact your PCs.

MyAgent Trojan Targets Defense and Aerospace Industries
FireEye Security experts are analyzing a targeted trojan that leverages emailed PDF files to gain access to systems and deliver its payload to specified networks in the aerospace, chemical, defense and tech industries.
"We have seen different versions of this malware arriving as an exe inside a zipped file or as a PDF attachment. In this particular sample, the exe once executed opens up a PDF file called "Health Insurance and Welfare Policy." In addition to opening up a PDF file, the initial exe also drops another executable called ABODE32.exe (notice the typo) in the temp directory."
The malware also uses JavaScript to assess which version of Adobe Reader is currently running on the host machine,and then executes attacks based on known vulnerabilities in the discovered version. Once the trojan has infected its host machine, it communicates with its command and control server, the user agent string and URI of which are hard-coded into MyAgent’s binary.
FireEye reports that most of the payloads are detected by updated antivirus software, based on research executed by running the binaries through VirusTotal.

Your Friend can help Investigators to Access your Facebook Profile
If you’re not already particularly picky about who you friend on Facebook, you might wantto think about rejiggering those privacy settings. It's not the backdoor access that the FBI has been pushing for, but US District Judge William Pauley III has now ruled that it and other law enforcement agencies are entitled to view your Facebook profile if one of your "friends" gives them permission to do so.
As GigaOm reports, a New York City federal judge ruled in a recent racketeering trial that it’s legal for police to view your Facebook profile if one of your friends grants them permission.
Better start sniffing out the rats on your friends list.
That’s because all of that data that you think is personal really isn’t that personal after all, according to the Judge. "Colon’s legitimate expectation of privacy ended when he disseminated posts to his friends because those friends were free to use the information however the wanted including sharing it with the Government."
Both government agencies and private companies alike are mining social media to gain additional knowledge. Whether it’s a criminal investigation like this one or insurance companies reportedly combing through Facebook profiles to determine the party at fault in an auto accident, the freedom and public nature of social media can work both for and against its users.
Ultimately, users have to be aware of the public status of online information as well as the ease with which it can be obtained. Don’t post anything you don’t want to be found or seen.

DSD & ASIO Websites Attacked by Anonymous for #OpAustralia
The anonymous Operation Australia
hackers have today again been busy with further attacks on the ASIO and DSD
website. The attacks have been taking place throughout the day and
continuing right now. The website http://www.dsd.gov.au/ appeared
to be down when checked not long ago as well as http://www.asio.gov.au/ which
was taken down again a short time ago.
The attacks have been part of the on
going operation that is fighting out against the purposed security
laws that the Australian government is attempting to bring into place
in the near future.
Earlier today a
member from #nulcrew released data from
an Australian server in the name of the operation and over
the past weeks we have seen many attacks across many different websites.

Malicious Olympic 2012 Android Apps & Domains
Whenever an important event takes place, new opportunities for cyber criminals, especially for those who develop attacks based on social engineering, arise. Currently, the whole world has its eyes glued to TV screens watching the London 2012 Olympic Games.
Anti-malware and anti-virus solutions provider Webroot has issued a warning that an app app called “London Olympics Widget,” which is described as an app that displays aggregated Olympic news coverage. In fact, it’s really just harvesting the user’s contact list and device ID while reading up on SMS messages too.
The package name is ‘com.games.London.Olympics.widget’. This app has a digital certificate claiming it was developed in New Delhi, India.
For this scam, cybercriminals create websites that are very appealing; some even look very professional that they make it seem that you are close to having access to live programming. Researchers explain that the crooks rely on black hat SEO techniques to make sure that their malicious websites show up among the first in search engine results.
The security firm has determined that close to 10,000 clicks have already been redirected to the fraudulent Olympics website.Overall, a number of 38,000 clicks have been redirected to such sites, the victims being spread out across 100 countries.
Webroot advises that consumers should take a close look at the author of the app and then search the name to see if it is in fact a reputable company and/or developer, as seen in the photo above. A way that consumers can protect themselves from becoming a victim of these types of online scams is by learning about social engineering so they can recognize it and avoid falling into these traps.

LinkedIn Data Breach Costs $1 Million
Business networking site LinkedIn has announced it took a hit of up to $1 million due to one of the year's largest reported data breaches. LinkedIn spent between $500,000 and $1 million on forensic work after a large number of passwords were breached, LinkedIn CFO Steve Sordello said on the company's earnings call today.
He said the 175-million-member company continued to strengthen its website's security and is expected to add $2 million to $3 million in costs in the current quarter toward those efforts.
“Part of adding value to our members every day means ensuring that their experience on LinkedIn is safe and secure,” he said.
“Since the breach, we have redoubled our efforts to ensure the safety of member account on LinkedIn by further improving password strengthening measures and enhancing the security of our infrastructure and data. The health of our network as measured by number of growth and engagement remains as strong as it was prior to the incident.”
After the leak was discovered, LinkedIn reset the passwords of accounts that they believed were frozen.The stolen passwords were camouflaged using an outdated cryptographic hash function, SHA-1, created by the National Security Agency. In addition to this weakness, LinkedIn failed to add additional security layers, such as salting the passwords, a technique which randomly appends a string of characters.
Following the attack, LinkedIn confirmed in a blog post the addition of new security layers, including the salting of passwords.
