A security researcher for AVG has discovered a new piece of ransomware called Fantom that masquerades as a critical Windows update. Victims who fall for the ruse will see a Windows screen acting like it's installing the update, but what's really happening is that the user's documents and files are being encrypted in the background. Fantom is based on the open-source EDA2 ransomware project, and unfortunately there's no way to decrypt the files without the culprit's help. Plain and simple, you're in a bad spot if you happen to fall for this one. While savvy computer users might spot the ransomware as a malicious attempt to wreak havoc, it's easy to see how a less experienced user could be tripped... Read more...
Go ahead and cue up Cartman's "No kitty, that's a bad kitty!" soundbite, only this time it's not in reference to stealing those delicious Cheesy Poofs. McAfee's mobile malware research division found a sample of ransomware for Android that it's calling "ElGato," and once infected, it can steal a user's SMS messages, among wreaking other kinds of havoc. ElGato has botnet capabilities and a web-based control panel service, McAfee says. It's an ornery piece of software that reveals itself as a humorous image of a cat on infected devices. In addition to silently swiping potentially sensitive SMS messages, once infected a remote hacker can encrypt the target's files and lock out the rightful owner... Read more...
It's beginning to look like some rather sophisticated hackers have made their way into Apple's core and crippled iCloud security so severely that some iPhones have essentially been held hostage. A few iPhones here and there might not seem like a big deal, but ultimately, there could be a staggering 40 million iCloud accounts (approximately) at risk here. According to CSO Online, some iPhone users, dating back to February this year, have found their devices compromised, held hostage by Russian hackers. The attack is almost too simple. An iCloud account is broken into (with the help of leaked credentials), and the service's "Find My iPhone" feature is used to put the phone into Lost mode. From... Read more...
It’s been a rough week for Adobe and its Flash plugin. This week, Microsoft announced that it is hitting the pause button on unnecessary and excessive Flash content on webpages, and now we’re learning that Adobe had to scramble to patch up yet another zero-day exploit in Flash. This latest exploit is especially nasty as it uses a security hole found within Flash to allow nefarious parties to infiltrate Windows 10 machines and install ransomware. As we’ve seen by recent ransomware outbreaks at hospitals around the country, this is serious business. The exploit was initially discovered by Trend Micro researchers on March 31st, while fellow security researchers Proofpoint, Sophos and FireEye have... Read more...
Over the past few years, ransomware has become an ever growing threat to enterprise and personal users alike. If you’re unfamiliar with ransomware, it’s a piece of malware that infects a system, usually encrypts a user’s personal data – like photos, office documents, PDFs and the like – and then forces the user to pay a ransom for the decryption key.To date all of the known, fully-functional ransomware attacks have targeted systems running Microsoft Windows, but a brand new variant has hit the web targeting systems running Apple’s Mac OS X.An Apple MacBook Running OS XPalo Alto Networks discovered the ransomware a few days ago and posted a bulletin on its website.

A medical center located in Hollywood, California, paid hackers 40 bitcoins worth nearly $17,000 in U.S. currency to decrypt its files that were being held ransom. The ransom amount is far less than the $3.6 million that was being thrown around when news of the security breach went public, but is no less disheartening that those responsible were able to pull something like this off. Things went sour for Hollywood Presbyterian Medical Center when malware spread on its computer systems earlier this month. Known as ransomware, the malware encrypted critical files across the medical center's network, including medical records, forcing staff to turn off all systems to prevent it from spreading further....

Could you go a full day without using your PC? It might not be all that difficult on a casual basis, but for workers at Hollywood Presbyterian Medical Center, they've had the challenge of servicing patients without the aid of any computer systems for over a week due to a malware outbreak and subsequent ransom demand.A local computer consultant said the ransom is in the neighborhood of 9,000 Bitcoins, which is about $3.6 million in U.S. currency. The hackers responsible likely chose Bitcoin as their payment method of choice because the cryptocurrency is anonymous and difficult to trace, especially after they've been laundered.This is no harmless prank, and not just because of the amount of money...

It seems that it was just yesterday that someone had to know a thing or two about software and programming to wreak havoc on fine upstanding Internet citizens via malware incursion. Ah, the good old days. Nostalgia aside, though, one cannot help but feel rattled by the news that security researchers at McAfee have discovered new software with which the oh-so-nefarious out there can easily construct their own ransomware. And not only is such a product in the wild, but it is online software, too, accessible by anyone capable of navigating a keyboard and a TOR browser.  Dubbed Tox, the devil's tool raising the ruckus runs on TOR and is easy to work out and completely...

Thanks to antivirus software maker Kaspersky, you may not need to pony up to retrieve your files if your computer is infected with the hated CoinVault ransomware. The company announced that it has found a way to decrypt the files and is offering to help infected users for free. The big break came from a Dutch cybercrime police unit that was able to scavenge decryption keys from a server used by CoinVault. Kaspersky used the data to create a tool for decrypting locked files. The tool isn’t always successful, but if you’ve lost critical files to the malware, it’s worth a try. After all, the alternative is paying CoinVault for releasing your files.  CoinVault, which is can be triggered by clicking... Read more...

Lynton sent out an email to employees on Saturday discussing the attack, but couldn’t give much solace to the 3,800 employees that had their... Read more...

Since then, Sony Pictures has been investigating the possibility that it was North Korean hackers behind the attack, according to Variety.According to unnamed sources speaking to Variety, Sony has no evidence that the attack was carried out by an individual, or group, with ties to North Korea, but the company is looking into all possible sources.

It appears that Sony has become the victim of a massive ransomware hack which has resulted in the company shutting down. An unnamed source spoke to Business 2 Community claiming that the company shut down after its computers in New York and around the nation were infiltrated. The source, according to the website, is an ex-employee of Sony Pictures who has a friend that still works for the company. According to the source’s friend, allegedly, every computer in Sony’s New York Office, and every Sony Pictures’ office across the nation, bears an image from the hacker with the headline “Hacked By #GOP” which is then followed by a warning.  The hacker, or group, claims to have obtained corporate...

You know malware is a steadily growing problem, but if you aren’t tuned into the cyber security industry, you might not know just how fast the threat is exploding. Hackers are taking computers hostage, stealing credit card data at ever-increasing rates, and spammers are winning the email war. McAfee released a new report that documents trending malware problems and shines a light on Deep Web, the underbelly of the Internet. The browser remains a top entry point for cyber attackers. Image credit: McAfee It’s been a banner year for malware. Rootkits are a major problem, as are the autorun viruses that sit on USB drives, waiting for someone to plug the drive into a new PC. As McAfee... Read more...
