"On Thursday, two researchers plan to reveal an unpatched iPhone bug that could virally infect phones via SMS.
"If you receive a text message on your iPhone any time after Thursday afternoon containing only a single square character, Charlie Miller would suggest you turn the device off. Quickly.
"That small cipher will likely be your only warning that someone has taken advantage of a bug that Miller and his fellow cybersecurity researcher Collin Mulliner plan to publicize Thursday at the Black Hat cybersecurity conference in Las Vegas. Using a flaw they've found in the iPhone's handling of text messages, the researchers say they'll demonstrate how to send a series of mostly invisible SMS bursts that can give a hacker complete power over any of the smart phone's functions. That includes dialing the phone, visiting Web sites, turning on the device's camera and microphone and, most importantly, sending more text messages to further propagate a mass-gadget hijacking."

"Send more PoCs!""Microsoft has been forced to issue emergency patches for its Windows operating system after researchers discovered a way to bypass a critical security mechanism in the Internet Explorer browser.
"During a Wednesday talk at this week's Black Hat conference in Las Vegas, researchers Mark Dowd, Ryan Smith and David Dewey will show a way of bypassing the 'kill-bit' mechanism used to disable buggy ActiveX controls. A video demonstration posted by Smith shows how the researchers were able to bypass the mechanism, which checks for ActiveX controls that are not allowed to run on Windows. They were able to then exploit a buggy ActiveX control in order to run an unauthorized program on a victim's computer.
"Although the researchers have not revealed the technical details behind their work, this bug could be a big deal, giving hackers a way of exploiting ActiveX problems that were previously thought to have been mitigated via kill-bits."

"A critical ActiveX vulnerability used by hackers to exploit Microsoft Corp.'s Internet Explorer browser is a prime candidate for another Conficker-scale attack, security experts said.
"On July 6, just hours after security companies reported that thousands of compromised sites were serving up exploits, Microsoft acknowledged the flaw in the ActiveX control that can be accessed using IE. The bug has been used by hackers since at least June 9.
"Microsoft said it will issue a patch for the flaw on July 14..."

"Denial-of-service attacks against government Web sites in this country and South Korea appear to have had little impact and are not particularly sophisticated, experts say.
"`It’s a very noisy attack,` said Rick Howard, intelligence director at VeriSign iDefense, which provides cybersecurity and intelligence services for private- and public-sector organizations. `Everyone in government says it didn’t affect them that much.`
"`It’s been more of a nuisance,` said Phil Neray, vice president of security Strategy at Guardium. `We have countermeasures for denial-of-service attacks.`
"Several security companies have obtained the malicious code used to carry out the attacks. Symantec Corp. identified it as W32.dozer and a variant of the MyDoom worm that has infected a large number of computers."

"The number of exploits being written to target specific software vulnerabilities could be at all-time highs, new threat figures have suggested.
"Fortinet's Threatscape report for June, which actually covers the period between 21 May and 20 June, reveals that of the 108 new vulnerabilities added to its firewall intrusion detection system in the period, 62 were being actively exploited.
"This is equivalent to a 57.4 percent exploit rate, a rise over previous months and in line with increasing percentages and absolute numbers for recent months. For comparison, April-May exploit rates stood at 46.4 percent, with March-April at 31.3 percent..."
