Oracle today released an update to its ubiquitous Java software that fixes at least 17 security vulnerabilities in the program. The company is advising users to apply this update as soon as possible; it looks like most — if not… Read More »
A new resource for spotlighting organizations that are unwittingly contributing to the global spam problem aims to shame junk email havens into taking more aggressive security measures.
SpamRankings.net is a project launched by the Center for Research in Electronic Commerce at the University of Texas at Austin. Its goal is to identify and call attention to organizations with networks that have been infiltrated by spammers.
Adobe released an emergency security update today to fix a vulnerability that the company warned is being actively exploited in targeted attacks designed to trick the user into clicking on a malicious link delivered in an email message. The vulnerability… Read More »
Google warned on Wednesday that hackers were launching targeted phishing attacks against hundreds of Gmail account users, including senior U.S. government officials, Chinese political activists, military personnel and journalists. That story, as related in a blog post on the Official Google Blog, was retold in hundreds of media outlets today as the latest example of Chinese cyber espionage: The lead story in the print edition of The Wall Street Journal today was, “Google: China Hacked Email.”
The fact that hackers are launching extremely sophisticated email attacks that appear to trace back to China makes for great headlines, but it isn’t exactly news. I’m surprised by how few media outlets took the time to explain the mechanics behind these targeted attacks, because they offer valuable insight into why people who really ought to know better keep falling for these attacks. I also think a more complete accounting of the attacks may give regular Internet users a better sense of the caliber of scams that are likely to target them somewhere down the road.
Some of the recent scams that used bogus security alerts in a bid to frighten Mac users into purchasing worthless security software appear to have been the brainchild of ChronoPay, Russia’s largest online payment processor and something of a pioneer in the rogue anti-virus business.
Since the beginning of May, security firms have been warning Apple users to be aware of new scareware threats like MacDefender and Mac Security. The attacks began on May 2, spreading through poisoned Google Image Search results. Initially, these attacks required users to provide their passwords to install the rogue programs, but recent variants do not, according to Mac security vendor Intego.
A few days after the first attacks surfaced, experienced Mac users on an Apple support forums began reporting that new strains of the Mac malware were directing users to pay for the software via a domain called mac-defence.com. Others spotted fake Mac security software coming from macbookprotection.com. When I first took a look at the registration records for those domains, I was unsurprised to find the distinct fingerprint of ChronoPay, a Russian payment processor that I have written about time and again as the source of bogus security software.
Most Web sites use JavaScript, a powerful scripting language that helps make sites interactive. Unfortunately, a huge percentage of Web-based attacks use JavaScript tricks to foist malicious software and exploits onto site visitors. To protect yourself, it is critically important to have an easy method of selecting which sites should be allowed to run JavaScript in the browser.
It is true that selectively allowing JavaScript on known, “safe” sites won’t block all malicious scripting attacks: Even legitimate sites sometimes end up running malicious code when scammers figure out ways to sneak tainted, bogus ads into the major online ad networks. But disallowing JavaScript by default and selectively enabling it for specific sites remains a much safer option than letting all sites run JavaScript unrestricted all the time.
Yes, I realize that’s an ambitious title for a blog post about staying secure online, but there are a handful of basic security principles that — if followed religiously — can blunt the majority of malicious threats out there today.
Adobe has released another batch of security updates for its ubiquitous Flash Player software. This “critical” patch fixes at least 11 vulnerabilities, including one that reports suggest is being exploited in targeted email attacks. In the advisory that accompanies this… Read More »
Microsoft issued just two updates today to fix at least three security flaws in its Windows and Microsoft Office products, a merciful respite following last month’s record-setting patch push. One of the patches issued today earned a critical rating, the company’s most serious.
Earlier this month, arts & crafts chain Michaels Stores disclosed that crooks had tampered with point-of-sale devices at store registers as part of a scheme to steal credit and debit card numbers and associated PINs. But new information on the investigation shows that stores all across the country have since discovered compromised payment terminals.
