Google has embarked on a final campaign to warn the remaining half million PCs it estimates could still be infected with the DNSChanger malware that they risk losing Internet connectivity on July 9.

Starting this week, any users of Google's search tools who are detected redirecting to DNSChanger's now substituted domains will be splashed the stark warning "Your computer appears to be infected" with an accompanying link offering remediation advice.

More than half of US businesses still rely on conventional firewalls or intrusion prevention systems to shield themselves from the scourge of DDoS attacks, a survey by services firm Neustar has found.

The survey of 1,000 US-based IT professionals across a range of industries found that only 3 percent were using DDoS mitigation systems or services, with a quarter claiming they had no protection whatsoever against the threat.

Researchers have noticed one of the first examples of Android "drive-by" malware from an ordinary website, a dangerous type of automatic attack more commonly used to infect Windows PCs.

Discovered by security company Lookout Mobile Security on a number of webistes, the decidedly odd "NotCompatible" Trojan is distributed using a web page containing a hidden iFrame.

McAfee antivirus founder John McAfee is reportedly taking legal advice after a raid on his Belize home by police resulted in the software entrepreneur's arrest and the death of his pet dog.

The raid in the early morning of 1 May by the country's armed 'Gang Suppression Unit' (GSU) allegedly involved the doors to McAfee's house being smashed down, his property ransacked, and his dog shot.

Malware criminals are on the hunt for Mac victims again, repurposing the Java-based vulnerability used by the Flashback bot to push a new drive-by web attack, security firm Sophos has reported.

It's a malware tactic that is taken for granted in the Windows world. A vulnerability in a common software interface -- in this case Java -- is hit multiple times by different malware campaigns, usually in quick succession.

The cost-saving culture of 'bring your own device' smartphones is tempting enterprises into taking risks they would not contemplate for conventional computing devices, a survey by Goode Intelligence has suggested.

The Third mSecurity Survey (summary PDF) confirmed that Apple's iPhone is currently the dominant device, present in 77 percent of in the surveyed businesses, ahead of BlackBerry on 70 percent and the rapidly rising Android on 65 percent.

The source of the Apple Mac Flashback Trojan was probably a large clutch of compromised US-based WordPress blog websites hijacked to push visitors to malware hosts, Kaspersky Lab research has revealed.

As has previously been established by various sources, between September 2011 and February of this year, the malware was distributed using social engineering attacks that asked users to download a bogus Adobe Flash Player plugin.

Cloud storage leader Dropbox might have serious competition at last. LogMeIn has announced the beta of its rival 'Cubby' service, featuring higher data limits, a P2P data sync feature and the promise of user-managed encryption keys.

Built on top of the company's proprietary Gravity Data Service platform, Cubby offers some flexibility missing from Dropbox, starting with its more generous free storage allowance of 5GB; Dropbox gives users 2GB.

RIM's former co-CEO Jim Balsillie wanted to shift the company from its dependence on BlackBerry hardware in favor of a future built as much on outsourcing data services, unnamed sources have told Reuters.

According to details of the reported plan, mobile carriers would have paid the company to run data and messaging over its network, offering non-BlackBerry (i.e Android, iPhone, or Windows Phone) users access to relatively cheap plans.

RIM's BlackBerry remains the clear leader in mobile security with market share leader Android lagging badly, a "strengths and weakness" analysis of the four big platforms has concluded.

Enterprise Readiness of Consumer Mobile Platforms rated each platform on the basis of a number of criteria, including general device security, app security, code signing, authentication, device wipe ability, firewalling, and virtualisation, assigning each category a score out of five.

The wave of "police Trojan" ransomware that has hit PC users across the developed world in the last year is probably the work of a single highly active Russian cybercrime gang, a forensic analysis by Trend Micro has concluded.

The Anonymous movement has pulled off one of its biggest hacktivist coups yet, successfully defacing hundreds of Chinese Government websites in a spectacular protest against Internet censorship.

Defacement attacks are frequent but the scale of what the previously unknown Chinese wing of the group and hackers invited via Twitter launched from March 30 onwards is still unusual.
