On December 22, 2022, LastPass released information regarding a security incident that was discovered in November 2022. Investigators determined that unauthorized actors accessed customer vault data. Due to the zero-knowledge approach used by LastPass, leaked customer vault data is still encrypted and requires the customer’s password for decryption.
LastPass also noted that the compromise in November was launched using information gained in a breach earlier in 2022.
Threat actors may be able to brute-force passwords and gain access to encrypted vault data. Customers at risk are those with weak passwords.
As a precaution, LastPass users may want to reset passwords for high-value accounts in LastPass and their master password.

An unknown threat actor announced on a data breach site that they had acquired data from 400 million Twitter users. The actor demanded $276 million for a promise to destroy the leaked data.
Leaked Twitter account information can include private messages, account information, and all tweets made by an individual. Attackers often use information such as this to launch further attacks.
Ensure that user awareness training includes information about breaches such as this one. Train users to understand that private information can be used in phishing campaigns, which can broadly impact individuals and their organizations.

A new strain of Linux malware has been observed exploiting known vulnerabilities in 19 WordPress plugins and themes. Wide-spread scanning and exploit automation are likely being performed to deploy this malware. A complete list of affected plugins and themes can be found here: https://news.drweb.com/show/?i=14646&lng=en&c=23.
Attackers are leveraging these vulnerabilities to deploy a backdoor to compromise websites and potentially be used to carry out more severe attacks against internal networks. Websites may be modified so visiting users clicking on compromised pages may be redirected to malicious sites serving malware or phishing pages. The malware may also contain functionality for performing brute-force attacks against WordPress administrator credentials.
Administrators should keep track of all WordPress components (including third-party) and ensure they are up-to-date. Strong and unique passwords for administrator accounts should be used and protected with multi-factor authentication where possible.

Reports from Citrix and the National Security Agency (NSA) indicate that unpatched Citrix Application Delivery Controller (ADC) and Gateway endpoints are being exploited. Vulnerabilities being exploited include CVE-2022-27510 and CVE-2022-27518 (CVSS scores: 9.8).
CVE-2022-27510 is an authentication bypass that can be exploited to gain unauthorized access to Gateway user capabilities, and CVE-2022-27518 is a remote code execution vulnerability that could result in the takeover of affected systems. Post-exploitation indicators could involve web shells to provide attackers with backdoor access to compromised servers. This type of access can also be used to perform attacks against other internal systems.
These vulnerabilities were addressed in the November 8 and December 13, 2022, updates. If not applied, administrators should look to do so as soon as possible. It is also recommended to perform regular external vulnerability scanning to discover vulnerabilities and weak configurations on public-facing systems.
