DeadBolt | Breaking Cybersecurity News | The Hacker News

Taiwanese network-attached storage (NAS) devices maker QNAP on Thursday warned its customers of a fresh wave of DeadBolt ransomware attacks. The intrusions are said to have targeted TS-x51 series and TS-x53 series appliances running on QTS 4.3.6 and QTS 4.4.1, according to its product security incident response team.  "QNAP urges all NAS users to check and update QTS to the latest version as soon as possible, and avoid exposing their NAS to the internet," QNAP  said  in an advisory. This development marks the third time QNAP devices have come under assault from  DeadBolt ransomware  since the start of the year. In late January, as many as 4,988 DeadBolt-infected QNAP devices were identified, prompting the company to release a forced firmware update. A second uptick in new infections was  observed  in mid-March.  DeadBolt attacks are also notable for the fact that they allegedly leverage zero-day flaws in the software to gain remote access and encrypt the systems.

ASUSTOR network-attached storage (NAS) devices have become the  latest   victim  of Deadbolt ransomware, less than a month after similar attacks singled out  QNAP NAS appliances . In response to the infections, the company has released firmware updates ( ADM 4.0.4.RQO2 ) to "fix related security issues." The company is also urging users to take the following actions to keep data secure – Change your password Use a strong password Change default HTTP and HTTPS ports. Default ports are 8000 and 8001 respectively Change web server ports (Default ports are 80 and 443) Turn off Terminal/SSH and SFTP services and other services you do not use, and Make regular backups and ensure backups are up to date The attacks primarily affect internet-exposed ASUSTOR NAS models running ADM operating systems including, but not limited to, AS5104T, AS5304T, AS6404T, AS7004T, AS5202T, AS6302T, and AS1104T.  Much like the intrusions targeting QNAP NAS devices, the threat actors claim t

As work ebbs with the typical end-of-year slowdown, now is a good time to review user roles and privileges and remove anyone who shouldn't have access as well as trim unnecessary permissions. In addition to saving some unnecessary license fees, a clean user inventory significantly enhances the security of your SaaS applications. From reducing risk to protecting against data leakage, here is how you can start the new year with a clean user list.  How Offboarded Users  Still  Have Access to Your Apps When employees leave a company, they trigger a series of changes to backend systems in their wake. First, they are removed from the company's identity provider (IdP), which kicks off an automated workflow that deactivates their email and removes access to all internal systems. When enterprises use an SSO (single sign-on), these former employees lose access to any online properties – including SaaS applications – that require SSO for login.  However, that doesn't mean that former employee

Taiwanese company QNAP has warned customers to secure network-attached storage (NAS) appliances and routers against a new ransomware variant called DeadBolt . "DeadBolt has been widely targeting all NAS exposed to the Internet without any protection and encrypting users' data for Bitcoin ransom," the company  said . "QNAP urges all QNAP NAS users to […] immediately update QTS to the latest available version." A query on IoT search engine Censys shows that at least 3,687 devices have been encrypted by the DeadBolt ransomware so far, with most NAS devices located in the U.S., Taiwan, France, Italy, the U.K., Hong Kong, Germany, the Netherlands, Poland, and South Korea. In addition, QNAP is also urging users to check if their NAS devices are public-facing, and if so, take steps to turn off the port forwarding function of the router and disable the Universal Plug and Play ( UPnP ) function of the QNAP NAS.
