CyberheistNews Vol 4 #47 Dec 2, 2014 Heads Up! New Hybrid Ransomware Replicates Like A Virus Here is a powerful piece of ammo to get (more) IT Security budget. SophosLabs labs' blog reported about a new Ransomware strain with a difference - this one is a true self-replicating parasitic virus! They call it VirRansom. This new strain is a hybrid that combines CryptoWall-like functionality with active self-replicating virus infections of all files it can find. And like the cybercrime Reveton family of malware, it locks the PC's main screen demanding 0.619 Bitcoin to let you back in. Yikes. Let me quote Sophos for a moment: "Worms vs. Parasitics: Most worms leave you with one, or perhaps a handful, of infected files that weren't there before and need to be deleted. "Parasitic viruses, in contrast, may leave you with hundreds of infected files on each computer, or thousands, or more. If you leave even one of those infected files behind after a clean-up, the infection will start up all over again. "Worse still, the infected files can't just be deleted, because they are your own files that were there before the infection started. That makes cleanup much trickier." *The good news:* The file encryption is not as advanced as CryptoWall, as the key to decrypt the files is contained in the malware itself. Your antivirus should soon be able to decrypt the files and restore them, unless the bad guys are constantly changing the encryption keys in which case it may take a day or more before your AV catches up. *The bad news:* This is a full-fledged virus which will spread across your network and doing a less than perfect job on the disinfection can easily lead to reinfection of your whole network. CryptoWall-encrypted files that you can't or don't decrypt are harmless garbage forever, but you can delete them. With VirRansom, files that you don't decrypt are still recoverable, but also still actively infectious. It gets nastier all the time. You can expect a VirRansom 2.0 soon where they might implement "new features" like industrial-strength encryption like CryptoWall where you only get the decryption keys after payment, and things like infection of your email server, where emails are converted to a worm for maximum dissemination of their malcode. (Think about the legal ramifications of something like this.) You can mitigate these types of threats through both technical measures and enforcing security policy. First some technical approaches: · The very first thing you need to do is test the Restore function of your backups and make sure it works. And have a full set of backups offsite. · Start thinking about asynchronous real-time backups so you can restore files with a few mouse clicks. · Get rid of mapped drives and use UNC links for shared folders. · Whitelisting software, which only allows known-good executables to run, starts to look more attractive by the month. Looking at the security policy angle, it's time to enforce best practices, and one of those is of course prevent these types of infections to begin with, through effective 5-th generation security awareness training, as the infection vector is your end-user opening up an attachment or clicking on a link. Find out how affordable this is for your organization.

Here are 4 actual examples of these online e-commerce order or package shipment phishing attacks that have come in over the last week. The first one is a bogus Home Depot order that they want you to click on and make your PC into a botnet zombie. Images at the full blog post here: http://blog.knowbe4.com/shipping-problem-phishing-attacks-here-is-how-they-look How Was Sony Pictures Hacked? Kevin Mandia, who was hired as the forensics expert wrote in a letter to Sony's CEO that the breach was unprecendented, well-planned and carried out by an "organized group". It's the most destructive cyber attack reported to date against a company on U.S. soil. As Terabytes of data were exfiltrated, there will be a treasure trove of confidential data which will be leaked over the next weeks or months. But how was Sony hacked? The Grugg recently tweeted: "Well, pretty much every single hacked network in the news can be summarized: 'It started with an email...'" I would not be surprised if this was the case with Sony as well. While security experts have been able to test the wiper malware employed against Sony Pictures Entertainment, they say they have not yet exactly determined how the malware infected Sony in the first place. "My educated guess would be that someone was targeted [with] a spear phishing e-mail, which granted access to a system," Tom Chapman, director of the cyber-operations group at cybersecurity firm EdgeWave, tells Information Security Media Group. "The hacker(s) then escalated privileges and took control of the mail server and possibly the Active Directory. From there, the hackers owned the system." The attackers appear to have had an edge, in that they seem to be very familiar with Sony's network topology. "We have been investigating the attack and discovered new pieces of malware that are likely related to the same attackers," says security researcher Jaime Blasco, labs director of security management and threat intelligence vendor AlienVault. "From the samples we obtained, we can say the attackers knew the internal network from Sony since the malware samples contain hardcoded names of servers inside Sony's network and even credentials/usernames and passwords that the malware uses to connect to system inside the network." The North Koreans are highly likely to blame. You might think that a country that has problems delivering enough electricity to its citizens would not be that sophisticated, but their hackers are trained by the Russians and the Chinese and Pyongyang runs some of its hacking operations out of a luxury hotel in nearby Shenyang, China. It is obvious that Sony's defense-in-depth security policy was deeply flawed in either incorrectly stating the right procedures or failing to enforce them. Not having the breach detection tools in place to spot terabytes of data leaving the building is another epic fail.
