However, before you reach for your wallet, we've set out a few simple steps you should take to ensure you remain safe when buying online.

Microsoft denies Xbox Live has been hacked

Some people that definitely should be more careful when online are the thousands of Xbox Live gamers that reported their accounts had been hacked this week. Reports began surfacing of users of the online gaming service from Microsoft for the Xbox console finding charges on their credit or debit cards for Microsoft Points that had been exchanged for extra content for a number of EA Sports games including FIFA 12, Madden and NBA. Microsoft denied that accounts had been hacked and instead blamed a phishing scam that claimed to offer free Microsoft points.
Deputy news editor CarrieSkinner: said "Microsoft denies Xbox Live has been hacked. Unauthorised purchases blamed on phishing scams".

18% of small firms have given customers access to personal Wi-Fi networks

Nearly one in five (18 percent) small businesses have given out their personal Wi-Fi details to customers so they can access the web from their premises, The Cloud revealed this week. Research by the public Wi-Fi network provider revealed 59 percent of small firms don't offer Wi-Fi to their customers, with 44 percent admitting they have no plans to do so, despite demand from customers. Of the 45 percent of small business owners who said they had been asked for Wi-Fi on their premises, 61 percent said they had been asked 'often or very often'.
"18% of small businesses have given customers their personal Wi-Fi network details so they can access the web," we said in a tweet.

Microsoft slashes upgrade times for Windows 8

Microsoft claimed this week that users will be able to complete a Windows 8 upgrade much faster, in some cases in one-tenth the time it took similar-configured PCs to upgrade to Windows 7. The time savings quickly accumulate the more files are on the to-be-upgraded PC, said Christa St. Pierre, a member of Microsoft's Setup and Deployment team, in a long entry on the company's "Building Windows 8" blog.
Editor MattJEgan tweeted: Microsoft slashes upgrade times for Windows 8 (file under 'believe it when I see it')".

Google Chrome update addresses high-severity flaw

Google released an update for Chrome 15 which addresses a high-risk vulnerability. The security issue is the result of an out-of-bounds memory write in the browser's JavaScript engine. Under normal circumstances such a vulnerability would allow remote code execution and would be considered critical. However, because Google Chrome uses a native sandbox that prevents attackers from executing malicious code, the severity of the bug was downgraded.
"Phew. Google Chrome update addresses high-severity flaw," we said.
