QNAP storage devices hijacked by UnityMiner cryptocurrency malware

QNAP is a famous company from Taiwan that manufactures hardware such as network-attached storage (NAS) devices that are used to provide complementary centralized storage and are demanded by both corporate and individual customers. The group of researchers representing 360Netlab received a number of reports on 2 March containing information about a new wave of attacks against QNAP NAS devices.

Such techniques as credential theft and brute-force attacks are often applied to hijack the devices associated with the Internet of Things (IoT). In the provided case, it is likely that remote code execution was enabled by the two vulnerabilities tracked as CVE-2020-2506 and CVE-2020-2507 respectively. “Such security threats as remote code execution and NAS devices hijacking may be triggered by non-correct access control and command injection vulnerabilities that are attributable to security issues of the Helpdesk”, – commented the representatives of QNAP.

F5 reveals flaw enabling remote code execution – BIG-IP Platform at risk!

On Wednesday, the company F5 Networks that is active in the field of application security published a warning regarding the detection of four critical vulnerabilities affecting a number of products. Denial of service (DoS) attacks, as well as unauthenticated remote code execution (RCE) on target networks, may have been enabled by the exploitation of vulnerabilities in question. 

The security patches cover seven related flaws (CVE-2021-22986…CVE-2021-22992). Felix Wilhelm, the specialist representing Google Project Zero, detected and reported on two out of seven flaws at the end of 2020.

Among these flaws, four flaws may cause damage to 11.6 and 12.x versions of BIG-IP, however, newer versions may be subject to damage as well. 6.x and 7.x BIG-IQ versions may be affected by the critical pre-auth RCE tracked as CVE-2021-22986. However, according to the statement made by F5, the company’s specialists do not have any information on whether these issues have been publicly exploited.

Vulnerable systems may have been fully compromised in case the vulnerabilities in question were successfully compromised and such threatening activities as DoS attack and remote code execution became a reality.
