'_csp File Extension' Ransomware

Posted: March 5, 2019

The '_csp File Extension' Ransomware is a file-locker Trojan that can keep content such as music, pictures, or documents from opening by encrypting them automatically. Having a backup out of the scope of the '_csp File Extension' Ransomware's payload is the simplest way of maintaining your files safe, since its encryption may not be decryptable without information that its threat actors hold for ransom. However, most well-designed anti-malware solutions should remove the '_csp File Extension' Ransomware automatically.

The Abbreviations of a Ransom Attempt

A file-locking Trojan that matches the symptoms of none of the known families of its type is launching attacks against unknown victims' files. The '_csp File Extension' Ransomware stands apart from similar software, not due to any fundamental changes in its campaign's strategy, but according to formatting and cosmetic details. The '_csp File Extension' Ransomware's threat actors, however, are showing a reasonable familiarity with their industry, unlike the so-called 'script kiddies' of some independent Trojans.

The '_csp File Extension' Ransomware encrypts JPG pictures and an unknown range of other formats (although PDFs, DOCs, XLSes, RARs, ZIPs, GIFs, and BMPs are representative of normally-vulnerable media) for keeping them from opening. Most file-locker Trojans append extensions onto the files' names, and the '_csp File Extension' Ransomware operates nearly the same way but uses an underscore ('_') instead of a period for its three-letter string. This minor difference is one that malware analysts haven't found in most file-locker Trojans, including all of the most important families operating in 2019, like the Crysis Ransomware, the Scarab Ransomware or EDA2.

The '_csp File Extension' Ransomware's ransom note carries a similarly-unusual name that has what malware experts are estimating as being a bracket-enclosed ID variable for the victim between its name of 'HOW TO DECRYPT' and the 'txt' extension. The ransom note, while unique in phrasing, is, otherwise, unremarkable, and recommends contacting either the BitMessage address or the threat actor's free e-mail for negotiations. Paying these ransoms may or may not give the victim any access to a file unlocker.

Taking the Time to Save Your Files from Emerging Assailants

With none of its characteristics lining up with a freely-decryptable family, the '_csp File Extension' Ransomware has the possibility of blocking any documents and other media for as long as the threat actor likes, including forever. Users can submit samples to interested cyber-security professionals for investigative efforts into the encryption but always should have backups for avoiding any dependency on such a solution. Malware researchers recommend saving backups to other devices entirely separated from Internet-accessible systems.

The '_csp File Extension' Ransomware campaign is active in Germany, but most file-locking Trojans coordinate attacks without much discrimination for national boundaries. The users should be careful about their Web-browsing settings, e-mail interactions, and password habits, which can be potential vectors for infections. A well-updated anti-malware program may block or remove the '_csp File Extension' Ransomware, but can only prevent, not undo, any media encryption.

The '_csp File Extension' Ransomware could be the first foray of an upcoming family of similar Trojans or a lone wolf. In either case, its campaign is a cause for worries among Windows users without any backup plans.
