Hackers have altered DNS records of websites hosted by Go Daddy, with the aim of infecting visitors with ransomware. The attackers are adding subdomains to the DNS records, pointing to a malicious IP address under their control, allowing victims to believe they are going to the right website, and for the pages to avoid various security protection mechanisms. This attack comes two months after an alleged attack on the Go Daddy network.
Android's app climate had some of its problems exemplified late Wednesday after Sophos discovered a fake version of Instagram for Android. At least one scam site has claimed to offer the app and copied much of the marketing into Russian.

Sophos today released a free piece of Mac security software, Anti-Virus Home Edition. The utility is based on the company's business software, and said to be full-featured with the same threat detection, cleaning and quarantining. It addresses both Mac and Windows threats, to prevent Macs from spreading Windows malware, and can detect new viruses. Once files are quarantined, they can be examined/or deleted.
Researchers at Matousec have found malware that could potentially compromise nearly every Windows XP system using current antivirus software. KHOBE (Kernel Hook Bypassing Engine) takes advantage of the vulnerable System Service Descriptor Table to trick Microsoft's OS into accepting rogue code. It allows a safe code thread to be scanned by antivirus apps but immediately swaps in a thread containing a virus or other attack, giving the malware free rein.
A new worm has begun targeting iPhones and iPod touches, however it only appears to attack jailbroken devices, according to the security company Sophos.
