"An attacker could exploit this vulnerability by intercepting, modifying and resubmitting an authentication request. " the security advisory reads.

Common Vulnerability Scoring System (CVSS) rated this vulnerability as highly critical vulnerability - base score is 10.

Cisco has issued a software update for all of the affected devices which will address this vulnerability.  There are currently no known workarounds that mitigate this vulnerability.

Cisco says the vulnerability is not being publicly exploited by any attackers.  It was reported by a security researcher Gustavo Javier Speranza.

BitStamp hacked, users are receiving spam mail containing malware

European Apple users targeted with phishing emails

A new phishing campaign targeting European users of Apple store which promises to offer a discount.

Security researchers at Kaspersky have spotted a new spam mail targeting Apple users, tricks users into thinking that they can get discounts of 150 euros by just paying 9 euros.

"Apple is rewarding its long-term customers.  Your loyalty for our products made you eligible for buying an Apple discount card" The spam mail reads.

The spam mail asks users to download an attached HTML file and fill the form, where users are being asked to enter personal information as well as credit card information.

Critical Bug in GnuTLS library affects Linux and hundreds of apps


A critical bug(CVE-2014-0092) in handling the errors in the GNU Security library GnuTLS affects hundreds of software packages including RedHat, Debian and Ubuntu distros.

According to RedHat security advisory, there is a coding error in GnuTLS which fails to handle certain errors that could occur during the verification of an X.509 certificate, results in reporting 'a successful verification'.

"An attacker could use this flaw to create a specially crafted certificate that could be accepted by GnuTLS as valid for a site chosen by the attacker." the advisory reads.

The bug exists in returning the value in the verify.c file (https://www.gitorious.org/gnutls/gnutls/commit/6aa26f78150ccbdf0aec1878a41c17c41d358a3b?diffmode=sidebyside).  It appears the uninitialized variable "result" is causing the problem.  There is also another coding error where it returns value of issuer_version when issuer_version is less than zero, instead of returning zero.  And, when result is less than zero, it goes to 'cleanup' location instead of 'fail'.

Nikos Mavrogiannopoulos from Red Hat Security Technologies Team discovered this security flaw, while doing an audit of GnuTLS for the RedHat.

Users are advised to upgrade to the latest GnuTLS version (3.2.12 or 3.1.22) or apply the patch for GnuTLS 2.12.x.

Bitcoin Exchange Poloniex website got hacked

Here comes another hacking news related to Bitcoin.  Multi crypto currency exchange Poloniex has announced today that their website suffered a cyber attack, leading to Bitcoins being stolen from their company.

On BitcoinTalk forum, the company explained how hackers stole the Bitcoins; Placing multiple withdrawls requests at the same time will result in negative balance but still the request is being processed.

"Another design flaw is that withdrawals should be queued at every step of the way. This could not have happened if withdrawals requests were processed sequentially instead of simultaneously" the forum post explaining another bug reads.

One of the forum's member gave a link to the attacker's bitcoin address "https://blockchain.info/address/1Ktq7TE3J5vZ3c99M5weqKfFcNkHQdqPrq".  It appears the loss is around $50,000(76BTC).

The owner of Poloniex said he will take the full responsibility and will repay the debt of BTC.  However, due to shortage of 12.3% in funds, the company will temporarily deduct 12.3% balance from all accounts.

"If I had the money to cover the entire debt right now, I would cover it in a heartbeat. I simply don't, and I can't just pull it out of thin air." he said.

Bitcoin Bank Flexcoin website hacked, $600,000 worth Bitcoins stolen

Bitcoin Bank "FlexCoin" website has been closed after reportedly hackers attacked the site and stole 896 bitcoins worth $600,320.

The organization claims the attack happened on March 2nd, in which attackers transferred the bitcoins to two different addresses.

"As Flexcoin does not have the resources, assets, or otherwise to come back from this loss, we are closing our doors immediately." the company posted a statement on its main page.

The bitcoins stored in cold storage were not affected by this breach, as coins were held offline.  Those users who put their coins into cold storage will be contacted by Flexcoin and asked to verify their identity.

For others, the company pointed out a link to TOS, where it says "Flexcoin Inc is not responsible for insuring any bitcoins stored in the Flexcoin system. You are entering into this agreement with Flexcoin Inc. You agree to not hold Flexcoin Inc, or Flexcoin Inc's stakeholders, or Flexcoin Inc's shareholders liable for any lost bitcoins."

The company says they are working with law enforcement and trying to find the cause of the security breach.  

Hackers compromise 300,000 SOHO routers and changed DNS to redirect to attacker site

A security researchers at Team Cymru have uncovered a Pharming attack campaign targeting Small office and Home office(SOHO) routers.  So far, more than 300k SOHO routers have been compromised.

The hackers altered DNS settings  to use IP addresses '5.45.75[.]11' and '5.45.75[.]36' on the compromised devices in an effort to redirect the victim to attacker's website.

Most of the compromised devices are from Vietnam.  India is also to be one of the top countries affected by this campaign.  Other affected countries are including Italy, Thailand, Indonesia, Ukraine, Turkey, Colombia.

The affected routers are from number of manufacturers including Micronet, Tenda, D-Link, TP-Link.  Researchers say that affected devices are vulnerable to multiple exploits including CSRF attack, vulnerability in ZyXEL firmware.

The vulnerability in ZyXEL's ZynOS was discovered by researcher back in January which allows attacker to directly download the routers configuration file http://[IP Address]/rom-0.

So far, the attackers didn't seem to have abused the compromised devices.  But, the attack is similar to the attack against a number of Poland's banks.  In which, the attacker changed the DNS configuration in order to steal Online Banking login credentials.
