Emotet: The Return of the World’s Most Dangerous Malware
May. 12, 2022According to CISA, Emotet is among the most costly and destructive malware used against the private and public sectors, and Europol calls it the world’s most dangerous malware. This report shows the result of a dynamic analysis of an Emotet Epoch4 loader sample and presents a list of IoCs extracted from that sample, with recommended mitigations.
Analysis of an ALPHV Incident
Apr. 22, 2022This report analyzes the files and tools used by an affiliate of the ALPHV ransomware group (aka BlackCat) during an attack that involved penetrating a SonicWall firewall and encrypting a VMware ESXi environment. New findings break down the malware's sophisticated behavior and present ways to avoid damage.
Night Sky Ransomware
Apr. 12, 2022The Night Sky ransomware was first reported by MalwareHunterTeam on January 1, 2022. Victims were asked to contact the attackers on contact[.]nightsky[.]cyou to pay for the ransom. If the victims refused to pay, attackers threatened to expose their data on a leak site. This is known as a double extortion ransomware. Night Sky provides an interesting view into the relationships among several ransomware families.
Mar. 30, 2022LAPSUS$ is a hacking group that has been active since 2021 and has breached several high-profile organizations, starting with major Brazilian government agencies and companies, then moving on to global businesses such as Microsoft, Nvidia and Okta. This loose collective of hackers is notable for using social engineering techniques and focusing on data exfiltration and public extortion rather than data encryption. This briefing reports on the group's victims, methods and indicators of compromise, and provides mitigation recommendations.
