Malware

New Iranian hacking tool leaked on Telegram

BlackSquid malware discovered by Trend Micro researchers

  • BlackSquid malware uses eight exploits to target web servers, network drives and removable drives. These exploits include EternalBlue, DoublePulsar, CVE-2014-6287, CVE-2017-12615, and CVE-2017-8464 and three ThinkPHP exploits for several versions. The malware was seen predominantly targeting Thailand and the US.
  • BlackSquid employs anti-virtualization, anti-debugging, and anti-sandboxing techniques to determine whether to continue with installation. It was observed dropping the XMRig Monero miner but, according to the researchers, could also be used to drop other payloads which could infect devices, incapacitate hardware, steal information, and more.
  • The researchers stated that despite the malware’s sophistication, several coding errors and ‘skipped routines’ suggest it may still be in its testing and development stage.

Ongoing Campaigns

Cybaze-Yoroi ZLab researchers publish update on Gamaredon attacks

  • The Cybaze-Yoroi ZLab team released an update following the Gamaredon attacks against Ukraine last month. They discovered a new email that is potentially linked to the group, which suggests that their attacks are ongoing.

Netscout researchers detect spike in Realtek SDK exploits

  • A spike was observed in exploit attempts targeting the Realtek SDK miniigd SOAP vulnerability CVE-2014-8361, between April 22nd, 2019 and May 10th, 2019. The attacks originated from Egypt and a large number of the exploit attempts were against South African routers, suggesting targeted attacks.
  • The researchers observed the Hakai DDoS bot being delivered on vulnerable devices. The Hakai bot supports HTTP flooding, TCP flooding, and UDP flooding. The Hakai variants in this campaign include a new vseattack function that performs a Valve Source Engine (VSE) query-flooding attack similar to the one found in Mirai botnet.
  • The researchers believe this activity is an attempt to recruit more bots and that the actors behind the exploitation attempts are seeking to expand their botnet.

‘Robbinhood’ Twitter account linked to Baltimore ransomware attacker

  • Researchers at Armor confirmed that the person(s) behind the ‘Robbinhood’ Twitter account, that appeared to be leaking confidential files, is linked to the attacker behind the Baltimore ransomware attack. Robbinhood is the name of the ransomware strain used in the Baltimore attack. The connection was made after the account holder posted the attack panel interface used to communicate with Baltimore during the attack.
  • The Robbinhood ransomware was initially believed to be powered by the leaked NSA hacking tool ‘EternalBlue,’ but according a recent analysis by malware analyst Joe Stewart, the Baltimore attack does not contain any EternalBlue exploit code. Stewart believes Robbinhood was set up to become a multi-tenant ransomware-as-a-service offering and also found a potential link to the GandCrab ransomware, a ransomware-as-a-service that has just announced it is shutting down.
