Afraidgate: Major Exploit Kit Campaign Switches from CryptXXX Ransomware Back to Locky

By mid-July 2016, the Afraidgate campaign stopped distributing CryptXXX ransomware. It is now distributing the “.zepto” variant of Locky. Afraidgate has been using Neutrino exploit kit (EK) to distribute malware after Angler EK disappeared in early June 2016. As we previously reported, this campaign continues to utilize gate domains using name servers from afraid.org.

PowerWare Ransomware Spoofing Locky Malware Family

Unit 42 has recently discovered a new variant of PowerWare, also known as PoshCoder, imitating the popular Locky ransomware family. PoshCoder has been encrypting files with PowerShell since 2014, and the new variant named PowerWare was reported in March 2016. The malware is responsible for encrypting files on a victim’s machine and demanding a ransom via the

Afraidgate: Major Exploit Kit Campaign Swaps Locky Ransomware for CryptXXX

In mid-April 2016, a campaign using Nuclear Exploit Kit (EK) to distribute Locky ransomware switched to using the Angler EK to install CryptXXX ransomware. This campaign uses gates registered through FreeDNS at afraid.org. We are calling this the Afraidgate campaign. Although we continue to see Locky distributed through malicious spam, we have not noticed Locky

Ransomware: Locky, TeslaCrypt, Other Malware Families Use New Tool To Evade Detection

Today we identified a new tool actively being used by the Locky ransomware family to evade detection and potentially infect endpoints. Unit 42 identified slight changes in Locky detonations through the AutoFocus threat intelligence service, correlating global data to discover a new tool being used to pack multiple ransomware families. Adversaries are constantly seeking new

Locky Ransomware Installed Through Nuclear EK

In February 2016, Unit 42 published detailed analysis of Locky ransomware. We certainly weren’t the only ones who saw this malware, and many others have also reported on it. Since that time, Locky has been frequently noted in various campaigns using malicious spam (malspam) to spread this relatively new strain of ransomware. When we initially

Locky: New Ransomware Mimics Dridex-Style Distribution

Ransomware persists as one of the top crimeware threats thus far into 2016. While the use of document-based macros for ransomware distribution remains relatively uncommon, a new family calling itself “Locky” has borrowed the technique from the eminently successful Dridex to maximize its target base. We first learned of Locky through Invincea and expanded on
