We occasionally discuss the complaints from video game publishers and developers about how used game sales are hurting them, and how they've been testing out countermeasures disguised as features to compensate. Now, industry analyst Michael Patcher has released a report which attempts to quantify that damage. Patcher estimates that used game sales and trades number around 100 million each year in the US. However, despite the immense number of transactions, he doesn't think the used game market is as detrimental to sales of new games as the publishers think. "The vast majority of used games are not traded in until the original new game purchaser has finished playing, typically well beyond the window for a full retail priced new game sale. Thus, while there may be some limited substitution of used game purchases when GameStop employees 'push' used merchandise upon consumers lined up to buy new games, the vast majority of used game purchases occur more than two months after a new game is released. ... To the extent that there is a substitution effect, we estimate that fewer than 5% of new game sales are impacted."

Hugh Pickens writes "The Telegraph reports that dozens of users of the recently released iPhone 3GS have reported overheating issues, with some iPhone owners unable to pick up the device because the handset gets so hot to the touch, while others say the casing turns pink with the heat. 'I am definitely experiencing issues with the iPhone running warm and quick battery life lost,' writes Tom Goldstein on one discussion board. 'The phone seems to warm up almost immediately if I am doing anything that pulls data over the network.' Some users have said the device has been too hot to put to their ear while making a phone call, and others say the overheating seems to occur when owners are using the iPhone's mapping software, which uses the handset's built-in GPS technology. Melissa J. Perenson writes at PC World: 'I became aware the handset had become very hot. Very, very hot — not just on the back, but the entire length of the front face, too.' Some gadget experts believe faulty batteries could be the cause of overheating and poor battery life. 'My guess is there's going to be a whole lot of batteries affected because these [iPhones] are from very large production runs,' said Aaron Vronko, who fixes iPods and iPhones. 'If you have a problem in the design of a series of batteries, it's probably going to be spread to tens of thousands [of device], if not hundreds of thousands, and maybe more.'"

An anonymous reader sends news from The Washington Post's Security Fix blog of a new Trojan horse program that takes click fraud to the next level. The Trojan, dubbed FFsearcher by SecureWorks, was among the pieces of malware installed by sites hacked with the Nine-Ball mass compromise, which attacked some 40,000 Web sites this month. The Trojan takes advantage of Google's "AdSense for Search" API, which allows Web sites to embed Google search results alongside the usual Google AdSense ads. (SecureWorks' writeup indicates that Yahoo search is targeted too, but the researchers saw no evidence if the malware redirecting Yahoo searches.) While most search hijackers give themselves away on the victim's machine by redirecting the browser through some no-name search engine, FFsearcher "...converts every search a victim makes through Google.com, so that each query is invisibly redirected through the attackers' own Web sites, via Google's Custom Search API. Meanwhile, the Trojan manipulates the victim's PC and browser so that the victim never actually sees the attacker-controlled Web site that is hijacking the search, but instead sees the search results as though they were returned directly from Google.com (and with Google.com in the victim browser's address bar, not the address of the attacker controlled site). Adding to the stealth is the fact that search results themselves aren't altered by the attackers, who are merely going after the referral payments should victims click on any of the displayed ads. What's more, the attackers aren't diverting clicks or ad revenue away from advertisers or publishers, as in traditional click fraud: They are simply forcing Google to pay commissions that it wouldn't otherwise have to pay." If FFSearcher were the only piece of malware on the machine, it would have a better chance of staying under the radar.

snydeq writes "Microsoft pulled the plug on Windows XP a year ago today, no longer selling new copies in most venues. Yet according to a report from InfoWorld, various downgrade paths to XP are keeping the operating system very much alive, particularly among businesses. In fact, despite Microsoft trumpeting Vista as the most successful version of Windows ever sold, more than half of business PCs have subsequently downgraded Vista-based machines to XP, according to data provided by community-based performance-monitoring network of PCs. Microsoft recently planned to further limit the ability to downgrade to XP now that Windows 7 is in the pipeline, but backlash against the licensing scheme prompted the company to change course, extending downgrade rights on new PCs from April 2010 to April 2011."
