Social Engineering Skype Support to Hack any Account Instantly

Skype Social Engineering AttacksYou can install the industry’s strongest and most expensive firewall. You can educate employees about basic security procedures and the importance of choosing strong passwords. You can even lock-down the server room, but how do you protect a company from the threat of social engineering attacks?

For any of you that are involved in security awareness efforts, you know what I am talking about. It could happen tomorrow, it could happen today or it might already have happened.

In a recent disclosure posted by renowned hacker and developer DarkCoderSc (Jean-Pierre LESUEUR) explained that how one can easily Socially Engineer Microsoft Skype Support team to get access to any skype account.

From a social engineering perspective, employees are the weak link in the chain of security measures in place. He simply used the weakness of Skype password recovery system itself.

One simply need to request a new password to Skype support and asking to change the password. After the initial step one needs to proof the real ownership of the account requested. You must give 5 contacts accounts to the support desk.

That’s easy because you just have to add 5 fake temporary accounts to the target account and its done. Another option is to simply ask the target what people he know on Skype. That option wasn’t that hard because I have over 1000 contacts.” he suggests the trick.

Within few seconds attacker can become owner of any victim account by proving very basic information to support team.

Also Microsoft’s Support Team should make a serious effort to communicate better to their customers. At the moment they do not seem to care that much about their customers.

Anonymous Hack Hands WikiLeaks 2 Million Syrian Emails

Anonymous WikiLeaksHacktivist group Anonymous is claiming responsibility for an attack on the computer systems of the Syrian government and its evil overlord Bashar Assad thanks to which over two million emails ended up in the hands of whistle-blowing site WikiLeaks.

As of last Thursday, the site began drip-feeding sections of the ‘Syria Files’ to its selected media partners, and given there are a total of 2.4m emails from 680 separate domains going all the way back to August 2006, it could take some time.

Anonymous revealed in a press release that its Op Syria team – comprising members of Anonymous Syria, AntiSec and sometime collaborator the Peoples Liberation Front – first breached multiple domains and servers in the war-torn country back in February.

So large was the data available to be taken, and so great was the danger of detection (especially for the members of Anonymous Syria, many of whom are ‘in country’) that the downloading of this data took several additional weeks,” the release said.

Not knowing quite what to do with the huge treasure trove of information it had snarfed, the group handed it over to WikiLeaks, the organisation it had partnered with before in the hack of private intelligence firm Stratfor.

There were no details of exactly how the attack took place but given the usual MO of Anonymous, you can expect it took advantage of some pretty obvious web application vulnerabilities.

The hacktivist group was also keen to portray itself as a force for good offline as well as on, claiming six of its members carried medical supplies across the border and that it has been helping local activists and protesters avoid surveillance efforts by the Assad regime.

Anti-government activists in Syria have been targeted by phishing campaigns and spyware for months, most recently the BlackShades Trojan which spreads via compromised Skype accounts.

Crack RSA SecurID 800 Secret Key in 13 Minutes

RSA SecurID 800RSA’s SecurID 800 is one of at least five commercially available security devices susceptible to a new attack that extracts cryptographic keys used to log in to sensitive corporate and government networks.

Scientists have devised an attack that takes only minutes to steal the sensitive cryptographic keys stored on a raft of hardened security devices that corporations and government organizations use to access networks, encrypt hard drives, and digitally sign e-mails.

The exploit, described in a paper to be presented at the CRYPTO 2012 conference in August, requires just 13 minutes to extract a secret key from RSA’s SecurID 800, which company marketers hold out as a secure way for employees to store credentials needed to access confidential virtual private networks, corporate domains, and other sensitive environments. The attack also works against other widely used devices, including the electronic identification cards the government of Estonia requires all citizens 15 years or older to carry, as well as tokens made by a variety of other companies.

“They’re designed specifically to deal with the case where somebody gets physical access to it or takes control of a computer that has access to it, and they’re still supposed to hang onto their secrets and be secure,” Matthew Green, a professor specializing in cryptography in the computer science department at Johns Hopkins University, told Ars. “Here, if the malware is very smart, it can actually extract the keys out of the token. That’s why it’s dangerous.” Green has blogged about the attack here.

It’s this version of the attack the scientists used to extract secret keys stored on RSA’s SecurID 800 and many other devices that use PKCS#11, a programming interface included in a wide variety of commercial cryptographic devices. Under the attack Bleichenbacher devised, it took attackers about 215,000 oracle calls on average to pierce a 1024-bit cryptographic wrapper. That required enough overhead to prevent the attack from posing a practical threat against such devices. By modifying the algorithm used in the original attack, the revised method reduced the number of calls to just 9,400, requiring only about 13 minutes of queries, Green said.

Other devices that store RSA keys that are vulnerable to the same attack include the Aladdin eTokenPro and iKey 2032 made by SafeNet, the CyberFlex manufactured by Gemalto, and Siemens’ CardOS, according to the paper.

Hacker Demanded $50,000 for not releasing Stolen Symantec Source Code

Norton Source CodeAccording to email transcripts posted to Pastebin yesterday, and confirmed by the company, a group of hackers attempted to extort $50,000 from Symantec in exchange for not releasing its stolen PCAnywhere and Norton Antivirus source code.

Hackers associated with the group Anonymous known as the Lords of Dharamaja leaked what appears to be another 1.27 gigabytes of source code from Symantec Monday night, what they claim is the source code of the Symantec program PCAnywhere.

A 1.2GB file labeled “Symantec’s pcAnywhere Leaked Source Code” has been posted to The Pirate Bay.

The leak comes as little surprise: Symantec had previously revealed that the hackers had obtained 2006 versions of that code along with other Symantec products from the same time period, and warned users of PCAnywhere to disable its functionality until they patched the program earlier this month.

The emails between Symantec employee Sam Thomas and the hacker(s) Yamatough, began in January. Symantec confirmed in a statement that it had contacted law enforcement after confirming the theft of the code and that the email exchange was, in fact, part of a criminal investigation. The email thread ended yesterday with Yamatough threatening to immediately release the code.

FBI Shuts Down Megaupload, Anonymous Shut Down FBI

Anonymous MaskHacktivist group Anonymous have compiled and published a dossier containing personal information about employees of the Motion Picture Association of America (MPAA) and US Democratic party leaders and their families.

The hacking group released a document listing the websites they planned to attack along with the names of US Democratic Party leaders and MPAA employees and their families.

The details included property values, work and home phone numbers and addresses as well as the names, ages and schools of the member’s children.

The group – who go by @YourAnonNews on Twitter – took credit for shutting down the Bureau’s official website FBI.gov earlier today, which as of 4.25pm AEST continues to display an error message.

They said the attack is in retaliation for the FBI shutting down popular file-sharing website Megaupload.com and charging the founders for online piracy.

Megaupload Limited and sister company Vestor Limited generated “more than $175 million in criminal proceeds” and caused “more than half a billion dollars in harm to copyright owners” through the piracy of “numerous types of copyrighted works,” the US Justice Department and FBI said in a joint statement.

The founder of the file-sharing websites 37-year-old Kim Schmitz, also known as Kim Dotcom and three others faced a New Zealand court today and said the group had “nothing to hide”.

But Anonymous hit back shutting down the websites of the US Department of Justice and Universal Music Group.

“The government takes down #Megaupload? 15 minutes later #Anonymous takes down government & record label sites,” they wrote on Twitter.

“We Anonymous are launching our largest attack ever on government and music industry sites. Lulz. The FBI didn’t think they would get away with this did they? They should have expected us,” they wrote on website Pastebin.

New Zealand’s police website police.govt.nz has also allegedly been targeted by the group after as Dotcom, Batato and two others were arrested in Auckland by New Zealand authorities carrying out warrants on behalf of the US for pirate material.
