May also be reported as Ykcol, but it really is Locky.

I’m not generally in favour of fighting malice with malice, but quite a few researchers who’ve come across this story have been observed trying to conceal an expression of glee, especially as there is no free decrypter for Locky.

Analysis by Malwarebytes: Look Into Locky Ransomware
Analysis by ESET: Analysis of the Locky infection process [4-4-16]
David Bisson reports on Graham Cluley’s blog about the ransomware commonly named Locky because of its use of a ‘.locky’ extension to files it has encrypted. What does a .locky file extension mean? It means you’ve been hit by ransomware
The same story is covered by HelpNet Security: Dridex botnet alive and well, now also spreading ransomware
Both articles refer to analysis by Palo Alto:
Paul Ducklin’s article for Sophos tells us about “Locky” ransomware: What you need to know. And John Leyden’s article for The Register also refers: Locky ransomware is spreading like the clap – Feeling Locky, punk? Well, do ya?
A SANS Newsbites newsletter has a number of interesting links to commentary on the Locky ransomware.
By Sabrina Berkenkopf for GData: Encryption Trojan Locky: What you need to know about the ransomware
An article from March 8th 2016 by Tim Ring for SC Magazine – Locky ransomware ‘on the rampage’ globally – is focused on Locky but also collates commentary from sources such as Fortinet and McAfee about how it relates to other major families, notably CryptoWall and TeslaCrypt.
Sorin Mustaca remarks that he’s sick and tired of seeing so many people affected by the current wave of ransomware attacks. He’s not alone there… His article About ransomware, Google malvertising and Fraud is worth reading for the description of how Locky spam may try to convince you to enable macros “if the data encoding is incorrect.” If you need more information, though, Paul Ducklin’s article for Sophos is characteristically informative and insightful: “Locky” ransomware – what you need to know
For ESET, Josep Albors warns Trojan Downloaders on the rise: Don’t let Locky or TeslaCrypt ruin your day.
Checkpoint [5-April-2016] New Locky Ransomware Variant Implementing Changes in Communication Patterns
Palo Alto [8th April 2016] Ransomware: Locky, TeslaCrypt, Other Malware Families Use New Tool To Evade Detection – “…multiple malware samples stood out due to what seemed like obfuscated API calls coming from a dictionary of embedded terms to resolve system functions and hide their true capabilities from commonly used static analysis tools.”

Proofpoint’s analysis of malware they call CryptXXX can be found here: CryptXXX: New Ransomware From the Actors Behind Reveton, Dropping Via Angler. Proofpoint observes that it has seen ‘an Angler EK into Bedep pass pushing both a ransomware payload and Dridex 222. Which may or may not be connected to the fact that Spamfighter has reported that Dridex is implicated in the distribution of ransomware. Spamfighter’s article – Security Researchers Discover Admin Panel of Dridex, Leverage Vulnerability and Hijack Backend – summarizes a report from Buguroo: Report: Analysis of Latest Dridex Campaign Reveals Worrisome Changes and Hints at New Threat Actor Involvement. The Buguroo page suggests that vulnerabilities in the Dridex infrastructure are responsible for its being used to distribute Locky. I haven’t read the full report – it requires registration.
