When people think about Internet security, they still think of the various bugs, flaws, and malware that pervade the online world as a Windows problem. Macs have long enjoyed special status thanks to limited market share, while smartphones aren't generally considered to be an attack vector, no matter which OS you prefer. That's clearly changing -- a new report from Palo Alto Networks illustrates how a new Trojan they call WireLurker doesn't just infect iOS devices -- it relies on Mac OS X vulnerabilities to do so. WireLurker contains a bevy of firsts and achievements. It's the largest malware to... Read more...
Avast, makers of the self-titled free antivirus software (along with paid Internet security suites), has discovered that the "Tinba Banker" Trojan is back in circulation, and this time it's targeting more than two dozen financial institutions in the United States. There are some big names among them, including Bank of America, HSBC, TD Bank, Chase, Wells Fargo, PNC, and more. This nasty piece of malware sneaks its way onto customer PCs through the Rig Exploit kit, which takes advantage of Flash or Silverlight exploits. Unfortunately for the victim, he or she can fall prey to the Trojan simply by... Read more...
Bitcoin digital currency is somewhat controversial as many people are just completely confused by it, but that hasn’t stopped Bitcoin from being used around the world--nor has it protected the currency from cybercriminals. SecureMac detailed the discovery of a Trojan called OSX/CoinThief.A that specifically targets Apple computers running Mac OS X. “The malware, which comes disguised as an app to send and receive payments on Bitcoin Stealth Addresses, instead covertly monitors all web browsing traffic in order to steal login credentials for Bitcoin wallets,” reads the post.

The Hand of Thief Trojan made waves among security experts when RSA first announced the for-sale malware. But now that RSA has had a chance to run additional analysis, the security arm of EMC is toning down its alert. It seems that the Hand of Thief is basically a prototype. The only people getting swindled at the moment is the would-be evil genius who buys this broken malware. RSA doesn’t see the Hand of Thief Trojan as a major threat at the moment, but the developer plans improvements. Image credit: RSA As it stands, the Hand of Thief Trojan isn’t stable. According to RSA, the software... Read more...
Linux users have long been able to claim that their platform of choice is about as safe as an OS can get, but that sentiment is getting a little harder to side with thanks to the recent discovery of the 'Hand of Thief' trojan - it's a bad one, so listen up. Hand of Thief's goal is to lead you to financial ruin by stealing sensitive information that you input into forms on supported Web browsers (Firefox and Chrome lead the pack here), such as those that you will use on banking websites. Hand of Thief's developers aren't going to be the ones milking your bank account dry, however. Instead, they're... Read more...
As the world shifts to mobile, hackers are adapting their strategies. According to Kaspersky Labs, the security firm just discovered a successful campaign by unknown hackers to target malware at a group of Android phone users. The target: Tibetan activists. The Conference app is malware. Image credit: Forbes The key to getting the attack off the ground was gaining access to the email of a well-known activist and then using that account to send malware-loaded emails to other activists.  Once the attachment was opened on an Android phone, the Trojan would gather contacts and other data and send...

Time and time again, we're reminded that Windows isn't the only operating system that malware writers target. It's the most popular platform for malware, sure, but it's not the only one. If you're a Mac user, don't let your guard down, and be especially leery of browsers plug-ins you run into, especially those that claim they're required to view a video. Install the wrong one and you'll end up infected with an adware Trojan. Security researchers at Doctor Web recently discovered Trojan.Yontoo.1, which masquerades as a critical browser plug-in on malicious movie trailer pages. Users are prompted... Read more...
On Friday, security firm Symantec discovered a Trojan called Backdoor.Makadocs, which in typical backdoor Trojan fashion accesses a compromised system and attempts to swipe data from it. The interesting bit is that it uses Google Docs as a proxy server to get around firewalls and connect to a C&C server, instead of attempting to connect directly. Using social engineering tactics to engage a user’s interest in the file, the Trojan arrives as a Rich Text Format (RTF) or Microsoft Word document; when a user opens it, the payload is delivered. Essentially all versions of Windows are affected,... Read more...
There seems to be a recurring phenomenon in the technology press, where any trojan that affects Linux or Macs becomes front page news. On the other hand, trojans that affect Windows are mostly ignored, perhaps because this is considered to be the normal state of affairs.  There are two common statements made in the discussions of these rare events: 1, No operating system will ever be secure from Trojans and 2, Linux/Mac only have fewer viruses because no one uses them. The first statement is almost correct, whereas the second one is a flat out myth in my opinion. Let me explain, and I’ll... Read more...

No one is arguing that Windows isn’t the biggest target for malware writers, but it’s starting to look like Microsoft’s OS isn’t alone. Threats for the Mac have made the occasional headline, and a new Trojan is making the rounds on both Mac and Linux. That’s right: a cross-platform virus. Wirenet, as it’s being called by Dr. Web (the Russian security company that discovered the malware), is designed to steal passwords. The bug goes after passwords stored in popular Internet browsers and sends them to a server, encrypted with AES. According to Dr. Web, the... Read more...
For years, Apple has propogated the myth that its computers were inherently secure thanks to its BSD roots, inherently better security management, or because Steve Jobs sacrificed puppies under the new moon to keep your platform safe. This created a dangerous perception that Macs were immune to viruses, trojans, or man-in-the-middle attacks. In reality, Apple has always benefited from security through obscurity -- when 90% or more of the world runs on PCs, PCs are the platforms hackers target. Apple has now quietly acknowledged this fact with a few judicious updates to its Max OS X page. The first... Read more...
Apple can't be too happy about having that Flashback malware news hit over half a million Mac users, and on a percentage basis, that's pretty extreme. But now, hopefully, the past can be the past. A new update in OS X Software Update patches Java, enabling the program (on Lion machines) to stop automatically executing Java applets. Users can still override the new default, and of course, this security patch "removes the most common variants of the Flashback malware." If you've been dealing with the issue, or just cautious not to get it, this update looks like one you shouldn't avoid.... Read more...
While many have dogmatically adhered to the idea that Macs are impervious to malware, some experts have been warning that it was only a matter of time before the Apple systems were hit with significant bugs. Findings like the one from Doctor Web late yesterday confirm that indeed, the malware threat looms large for Mac users. According to Doctor Web, a Russian antivirus vendor, 600,000 Macs were part of the BackDoor.Flashback.39 botnet. (Originally, the company reported the number at 550,000, but a Twitter post later upped it to over 600,000.) The Flashback Trojan isn’t especially new; variants... Read more...
