4 Ransomware Trends to Watch in 2019What is Cryptolocker ransomware? The ransomware under scrutiny gained notoriety mostly due to its denomination. Remember the original Cryptolocker from ? It was one of the prototypes of file-encrypting viruses as such. Although law enforcement agencies succeeded in taking down the underlying botnet in the course of the well-orchestrated Operation Tovar, different cybercrime groups ended up following suit afterwards and coined multiple copycats. Cryptolockeror Crypt0L0ckeris the newest one of these spinoffs. As opposed to most of its counterparts, it is professionally designed and features strong cryptographic characteristics. Cryptolocker mainly infects computers through malspam, that is, emails with booby-trapped attachments on board. This is the main catch that results in executing a VBScript or PowerShell instance, which in its turn downloads the ransomware from the C2 server. Then, the. To do this, it looks for entities whose formats match the built-in list of popular data types. The data formats targeted by this malady include Microsoft Office documents, PDF files, various image types, videos, archives and databases. Once the covert traversal process has been completed, the pest engages the above-mentioned RSA cipher to make the spotted items inaccessible and adds the. The warning window and desktop wallpaper provides one or a few email addresses for this purpose. By contacting the crooks, the infected users can learn the size of the ransom, which varies from incident to incident. The difference can be explained by the fact that different cybercriminal rings are distributing this ransomware on an affiliate basis, so they extort the amount they deem appropriate. Most of the time, the ransom is somewhere between 0. This manual contains the essentials of data recovery as well. The private key necessary for recovering the encoded objects is kept outside of the contaminated computer. This means that victims are bound to literally buy this secret combination from the attackers. Some users have reportedly been able to negotiate the ransom size. Even if it works and the amount is somewhat reduced, this is still a terrible deal. Cryptolocker

Ransomware encrypted file extensions
Bad Rabbit spreads through a fake Adobe Flash update on compromised websites. When the ransomware infects a machine, users are directed to a payment page demanding. This type of malware emphasizes the growing need for SaaS backup in addition to on-premises. CryptoLocker: Ransomware has been around in some form or another for the past two decades, but it really came to prominence in with CryptoLocker. Since then, hackers have widely copied the CryptoLocker approach, although the variants in operation today are not directly linked to the original. The word CryptoLocker, much like Xerox and Kleenex in their respective worlds, has become almost synonymous with ransomware. Like CryptoLocker, CryptoWall is distributed via spam or exploit kits. Crysis : Crysis ransomware encrypts files on fixed, removable, and network drives with a strong encryption algorithm making it difficult to crack in a reasonable amount of time. It's typically spread via emails containing attachments with double-file extension, which make the file appear as a non-executable file. In addition to emails, it can also be disguised as a legitimate installer for applications. Taking a page from the playbooks of Girl Scout Cookies and Mary Kay Cosmetics, these hackers outsource the infection process to partners in exchange for a cut of the profits. This is a proven strategy for achieving large volumes of malware infections at a faster rate. Hackers spread GoldenEye ransomware through a massive campaign targeting human resources departments. After the file is downloaded, a macro is launched which encrypts files on the computer. For each file it encrypts, GoldenEye adds a random 8-character extension at the end. The ransomware deletes a single file after the first hour, then deletes more and more per hour until the hour mark, when all remaining files are deleted. Unlike other variants, hackers must run LeChiffre manually on the compromised system. Cybercriminals automatically scan networks in search of poorly secured remote desktops, logging into them remotely and manually running an instance of the virus. LockerGoga : This strain of ransomware hit various European manufacturing companies, including Norsk Hydro. The ransomware infiltrated the company through a phishing email, causing a global IT outage and forcing the company to order hundreds of new computers. The malware is spread in an email message disguised as an invoice. When opened, the invoice is scrambled and the victim is instructed to enable macros to read the document. When macros are enabled, Locky begins encrypting a large array of file types using AES encryption. Petya overwrites the master boot record, rendering the operating system unbootable. The Word document, which is disguised as a debt collection notice, contains malicious macros.
10 Ransomware Attacks You Should Know About in 2019
At the end of each year for the last two years, I have written articles predicting trends in ransomware for the next coming year. Each article was a mix of accurate and inaccurate predictions — fortunately, more accurate than inaccurate. The biggest ransomware story ofarguably, happened in the city of Atlanta. The SamSam team hit the city hard, disrupting vital services for days and leaving some data completely unrecoverable. There were dozens of stories about cities, utilities, ports, and more that were infected with ransomware in Since ransomware attacks continue to challenge all types of organizations and not just healthcare and governmenthere are the anticipated trends in ransomware for In January ofRecorded Future was tracking ransomware campaigns. In February ofthat number was 1, and at the end of Januarywe were tracking 1, campaigns. While the number of ransomware variants continues to expand rapidly, the truth is that most of these campaigns are ineffective and die out quickly. An example of this phenomenon is the Cryptgh0st ransomware shown below. It was first discovered in May and by the end of August, virtually all mentions of the ransomware disappeared. Most successful campaigns in involved ransomware that relies on open Remote Desktop Protocol RDP servers as the initial access point. Ransomware families such as SamSam, BitPaymer, and CrySiS thrived, whereas other campaigns failed because they did not rely on web exploitation or phishing to gain access to victim networks. These campaigns look for networks that have internet-facing servers running the RDP service. Once the attackers have successfully gained access to the exposed system, they use it as a jumping off point into the core of the network, installing their ransomware onto target machines and often disabling backups and other protections. JBoss, FTP, and other services have all been targets of these groups, but open RDP servers are the preferred target because there are a lot of them, they are easy to find, and they are easy to exploit. Publicly accessible RDP servers are widely available for a couple of reasons. The second reason is that often organizations are not aware that the RDP service is running on internet-facing servers. This could be a configuration error, a failed security check, or it could be started by another service after the server is deployed. It is worth noting that with the recent takedown of the xDedic marketplace, the pool of readily available, low-priced RDP servers may be in short supply, at least until a new dominant marketplace emerges. Almost every headline-grabbing ransomware story in involved criminals who accessed the victim networks through a poorly secured RDP server, as shown in the timeline below. Note how the trend line stayed consistent throughout the year. Expect that to continue intoat least until organizations figure out how to secure or remove their RDP servers. The exception to the first two trends on this list continues to be GandCrab ransomware — one of the few widely deployed ransomware campaigns. GandCrab ransomware was first reported at the end of Januaryand since then, the team behind GandCrab has made dozens of adjustments and at least five new code releases. The GandCrab team is very responsive to security researchers, often including references to reports about their ransomware and how the team has adapted to those reports in their underground ads. Delivered primarily via phishing campaigns though they also use exploit kitsthe GandCrab team relies heavily on Microsoft Office macros, VBScript, and PowerShell to avoid detection, but will often incorporate new means of exploitation and avoidance as proof-of-concept code is released. Although consumer tools such as free mail services and anti-virus vendors have gotten better at detecting ransomware, GandCrab continues to find success, as shown in the timeline below.
