DarkSide ransomware jitter continues to reign this week. In a never-seen-before instance, the ransomware has been upgraded to target hidden files in disk partitions. The impact of this is likely to leave massive damage on organizations and an increased incentive to pay a ransom to recover files.
A deluge of spear-phishing campaigns is targeting users worldwide. One such campaign focuses on impersonating financial institutions in the U.S and the U.K in an attempt to distribute RATs. The other campaign is being targeted against taxpayers in South Korea, Australia, and the U.S. Both the campaigns are aimed at stealing sensitive information from users.

New DarkSide ransomware variant
Researchers have discovered a DarkSide variant capable of seeking out partition information and compromising multiple disk partitions. With this, the variant aims to find additional files to encrypt, causing more damage and putting pressure on organizations to pay the ransom. This variant also looks for the domain controller and connects to its Active Directory via LDAP anonymous authentication.
Threat actors impersonated Truist in a spear-phishing campaign that attempted to distribute RATs. The tailor-made phishing campaign spoofed the financial institution through registered domains, email subjects, and applications related to the institution. To increase the attack success rate, the attackers used malware currently undetected by anti-malware engines. Other U.S. and U.K financial institutions (Maybank, FNB America, and Cumberland Private) have also been impersonated in this spear-phishing campaign.
Another spear-phishing campaign
Taxpayers in South Korea, Australia, and the U.S. are being targeted in a phishing campaign that pretends to be from accounting ledgers. The subject line reads “Account Ledger for 2020-2021,” and the email body encourages recipients to verify the attachment. The campaign is used to distribute RATs.
