Twitter announced via its blog today that it has begun using a new method called Domain-based Message Authentication, Reporting and Conformance (DMARC) to help prevent email phishing. DMARC is actually a standard for preventing email spoofing, in order to make it harder for attackers to send phishing emails that appear to come from twitter.com addresses. Sometimes it's not easy to figure out if an email is legitimate or not. It implementing the SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) email message validation and authentication systems. Twitter says it started using the DMARC earlier this month. While the DMARC specification does need support from e-mail services, outfits including AOL, Gmail, Hotmail or Outlook and Yahoo already make use of it. It has also been implemented by services like Facebook, PayPal, Amazon and now Twitter. If you don't use Gmail or one of the other email providers listed above, you may not be protected. It ...

Today whitehat Hacker ' Nir Goldshlager ' reported ' The Hacker News ' that he discovered a very critical vulnerability in Facebook's OAuth system, that allowed him to get full control over any Facebook account easily even without ' allow or accept ' options. For this purpose he hunt the flaw in a very mannered way i.e Step 1) Understanding the OAuth URL Step 2) Finding a way to use custom parameters in URL Step 3) Bypassing OAuth ' Allow '...

A new malware threat for the Mac has been discovered that attempting to set up a secure connection for a remote hacker to connect through and grab private information. Dubbed " Pintsized " that uses a modified version of OpenSSH to potentially set up a remote connection into Mac accounts. This backdoor Trojan can be used to conduct distributed denial of service (DDoS) attacks, or it can be used to install additional Trojans or other forms of malicious software. Since the connection between the hacker and the machine is encrypted, it becomes very hard for the Trojan to be detected or traced. The threat has the potential to become serious, as it uses an exploit in OS X to bypass Gatekeeper and establish a reverse shell that creates a secure connection.  Trojan stays hidden by disguising itself as a file that is used for networked printers in Mac OS X. The location of the malware has been traced to this particular directory. This tactic conceals the Trojan an...

We identified a small number of systems within Apple that were infected and isolated them from our network ."
