Securin’s Threat Intelligence Aug 2, 2022 – Aug 5, 2022

In this edition, we bring you early warnings, trending news about cyber threats, and the accurate threat context. Check out which threat group is on the rampage, what vulnerability it could soon weaponize, and more.

Watch David Rushton talk about the Top Three Threats of the Week in his Threat Intelligence Podcast!

Here are the top threats of this week:

BlackCat attacks Enveco pipelines in Europe

Critical Authentication Bypass Vulnerabilities in VMware

RCE vulnerability affecting multiple DrayTek routers

CISCO fixes critical security vulnerabilities in VPN routers

Threats to watch out for


BlackCat attacks Enveco pipelines in Europe

The notorious ransomware group, BlackCat attacked Creos, the energy supplier in Luxembourg. Creos is a subsidiary of Enveco. During the attack none of the services were interrupted, but the customer portals were down for a while. It is estimated that sizable data of 150 GB containing contracts, agreements, passports, bills, and emails was stolen. BlackCat (ALPHV) has threatened to leak this data if their ransom demands are not met. BlackCat is believed to be a rebrand of DarkSide, known for its attack on the Colonial Pipeline.

The following CVEs are associated with BlackCat ransomware’s attacks: CVE-2016-0099,CVE-2019-7481,CVE-2021-31207,CVE-2021-34473,CVE-2021-34523.
BlackCat has carried out attacks against public and private organizations without distinction. Check out our comprehensive blog on BlackCat’s activities.

Critical Authentication Bypass Vulnerabilities in VMware

Two vulnerabilities, CVE-2022-31656,CVE-2022-31659 were discovered in VMware Workspace ONE Access, Identity Manager, and vRealize Automation products. If exploited, these vulnerabilities could affect local domain users and enable unauthenticated attackers to gain admin privileges.

VMware has released patches for these vulnerabilities as soon as news of their discovery was publicized.

Since this affects the on-premises devices, VMware has insisted that any organization using ITIL methodologies for change management should consider fixing this as an emergency and apply the patches.

There are no known exploits in the wild for these vulnerabilities.

RCE vulnerability affecting multiple DrayTek routers

DrayTek is a Taiwanese company manufacturing Small and Home Office routers. They are widely adopted in the UK, Taiwan, Vietnam, etc. Recently, a remote code execution vulnerability, CVE-2022-32548 was discovered in these devices. Over 200k devices have the vulnerable service exposed on the internet and can be exploited without user interaction when configured to be internet facing. A one-click attack can also be performed from within the LAN in the default device configuration. If exploited, it can lead to a full compromise of the device and may lead to a network breach and unauthorized access to internal resources.

CVE-2022-32548 has a CVSS score of 10.0, classifying it as extremely critical.

DrayTek has immediately released patches for this vulnerability and is urging its customers to apply them.


CISCO fixes critical security vulnerabilities in VPN routers

Unauthenticated, remote attackers can exploit two security flaws identified as CVE-2022-20842 and CVE-2022-20827 to execute arbitrary code or commands, resulting in denial of service (DoS) conditions on vulnerable devices. These vulnerabilities are caused by insufficient input validation in Cisco’s web-based management interfaces and web filter database update feature. In attacks with no user interaction, these vulnerabilities allow the attacker to take over without authentication..

There is no evidence of exploit in the wild.

CISCO has released patches for both the CVEs. Organizations using CISCO’s Small Business VPN routers are required to apply these patches with utmost urgency.

This week we’ve added a new section to track evolving threats.
