A security vulnerability in Microsoft Windows XP systems that was first disclosed a week ago is now being actively exploited by malicious Web sites to foist malware on vulnerable PCs, according to reports. Last week, Google researcher Tavis Ormandy disclosed… Read More »
Keystroke-logging computer viruses let crooks steal your passwords, and sometimes even read your e-mails and online chats. Recently, however, anonymous criminals have added insult to injury, releasing a keylogger that publishes stolen information for all the world to see at online notepad sharing sites such as pastebin.com.
Microsoft is warning Windows XP and Server 2003 users that exploit code has been posted online showing attackers how to break into these operating systems remotely via a newly-discovered security flaw.
The security flaw has to do with a weakness in the way the Windows Help and Support Center processes links. Both Windows XP and Server 2003 retrieve help and support information from a fixed set of Web pages that are included on a whitelist maintained by Windows. But Google security research Tavis Ormandy discovered that it was possible to add URLs to that whitelist.
I am often asked to recommend security software, but I think it’s important to bear in mind that staying secure is just as often about removing little-used software that increases your exposure to online threats. At the very top of my nix-it-now list is Java, a powerful application that most users have on their systems but that probably few actually need.
As promised, Adobe has released a new version of its Flash Player software to fix a critical security flaw that hackers have been exploiting to break into vulnerable systems. The update also corrects at least 31 other security vulnerabilities in the widely used media player software.
Criminals have launched an major e-mail campaign to deploy the infamous ZeuS Trojan, blasting out spam messages variously disguised as fraud alerts from the Internal Revenue Service, Twitter account hijack warnings, and salacious Youtube.com videos.
In its largest patch push so far this year, Microsoft today released 10 security updates to fix at least 34 security vulnerabilities in its Windows operating system and software designed to run on top of it. Separately, Apple has shipped another version of Safari for both Mac and Windows PCs that patches some four dozen security holes in the Web browser.
Adobe Systems Inc. warned late Friday that malicious hackers are exploiting a previously unknown security hole present in current versions of its Adobe Reader, Acrobat and Flash Player software.
“There are reports that this vulnerability is being actively exploited in the wild against both Adobe Flash Player and Adobe Reader and Acrobat,” the company said in a brief blog post published Friday evening. “This vulnerability could cause a crash and potentially allow an attacker to take control of the affected system.”
ATM skimmers, fraud devices that criminals attach to cash machines in a bid to steal and ultimately clone customer bank card data, are marketed on a surprisingly large number of open forums and Web sites. For example, ATMbrakers operates a forum that claims to sell or even rent ATM skimmers. Tradekey.com, a place where you can find truly anything for sale, also markets these devices on the cheap.
The truth is that most of these skimmers openly advertised are little more than scams designed to separate clueless crooks from their ill-gotten gains. Start poking around on some of the more exclusive online fraud forums for sellers who have built up a reputation in this business and chances are eventually you will hit upon the real deal.
David Green normally only accessed his company’s online bank account from his trusty Mac laptop. Then one day this April while he was home sick, Green found himself needing to authorize a transfer of money out of his firm’s account. Trouble was, he’d left his Mac at work. So he decided to log in to the company’s bank account using his wife’s Windows PC.
Unfortunately for Green, that PC was the same computer his kids used to browse the Web, chat, and play games online. It was also the same computer that organized thieves had already compromised with a password-stealing Trojan horse program.
A few days later, the crooks used those same credentials to steal nearly $100,000 from the company’s online accounts, sending the money in sub- $10,000 and sub-$5,000 chunks to 14 individuals across the United States.
