Malware

FuxSocy ransomware has strong similarities with Cerber ransomware

  • Researchers at MalwareHunterTeam identified a new ransomware, dubbed FuxSocy, which is heavily modelled on the now defunct Cerber ransomware. Security researcher Vitali Kremez discovered that FuxSocy and Cerber contain identical file exception lists, and scramble filenames and extensions in a similar way. The ransom note displayed by the new malware is also almost identical to the one displayed by Cerber.
  • Despite these similarities the new malware is not an identical clone of Cerber. The developers behind FuxSocy have added features that attempt to prevent their malware from running inside a virtual machine. The new ransomware also contains a feature that ensures that the malware fails to encrypt the entire file, however, these files still cannot be accessed by the user.  A decryption key for FuxSocy ransomware is not currently available.

Malicious spam campaign delivers AutoIT-compiled payloads

  • Researchers at Trend Micro identified a malware campaign that was delivering the AutoIT compiled payloads Negasteal malware and Ave Maria RAT, via spam emails. The emails that the researchers identified purported to be related to a shipment advisory and a financial document. 
  • In order to evade detection the campaign uses AutoIT-obfuscated ISO images files, as well as RAR and LZH-compressed archive attachments. The Negasteal malware variant can log and monitor keystrokes, monitor webcams, collect information saved on clipboards, and more. The researchers discovered that later versions of the campaign contained an Ave Maria RAT variant that can escalate privileges, modify Windows Defender, log users keystrokes, steal usernames and passwords, drop and create arbitrary files, and more. 
  • The researchers stated that upgrading email payloads from a ‘ typical trojan spy to a more insidious RAT’ suggests that the criminals are willing to deploy more destructive ransomware.

Ongoing Campaigns

Procter & Gamble’s First Aid Beauty online store infected in stealthy Magecart attack

  • Sanguine Security researcher Willem de Groot discovered a MageCart skimming script on the online store for First Aid Beauty. The payment skimmer was deployed on May 5th, 2019 and targeted US customers. If a user in another country accessed the site, the script would not run. The attack also fails to execute if a customer uses the Linux operating system. 
  • The attack was described as ‘fairly advanced’, and the script was encrypted and heavily obfuscated. The attack sought to acquire a victim’s card number, card expiration date, name of owner, and the card CVV code.
  • The researcher contacted First Aid Beauty on October 20th, 2019 but received no reply. Despite reporting the issue, the script remained active until approximately October 25th, 2019.

General News

Shadow Kill Hackers not behind DDoS attacks on South African banks

  • The cyberattack on Johannesburg on October 24th, 2019, initially thought to be a ransomware attack, did not encrypt any of the city’s computers. Rather, Shadow Kill Hackers, who claim to be behind the attack, stated they had gained access to the city’s Active Directory server and were the ones responsible for taking down the city’s website.
  • Additionally, initial reports stated that Shadow Kill Hackers were also responsible for Distributed Denial-of-Service attacks on several South African banks, yet the group has since denied such claims. Instead, these DDoS attacks may have been part of a global campaign by a group pretending to be the Russian group Fancy Bear.
