Several vulnerabilities have been discovered in Minetest, a sandbox video game
and game creation system. These issues may allow attackers to manipulate game
mods and grant them an unfair advantage over other players. These flaws could
also be abused for a denial of service attack against a Minetest server or if
user input is passed directly to minetest.deserialize without serializing it
first, then a malicious user could run Lua code in the server environment.
Several vulnerabilities have been discovered in Expat, an XML parsing C
library, which could result in denial of service or potentially the
execution of arbitrary code, if a malformed XML file is processed.
A slow response to a data breach or other cybersecurity incident can cost companies time and money, as well as damage to their reputation. To help companies accelerate their response to cybersecurity incidents, Magnet Forensics is offering a new application, Magnet Automate Enterprise, designed to automatically trigger investigations into security breaches and synchronize incident detection and response tasks by third party tools.
Magnet Forensics has a track record for developing investigation software for the processing of evidence from computers, mobile devices, IoT devices and cloud services, and has had a strong user base among law enforcement and government agencies. The new software is geared specifically for enterprises, allowing them to recover evidence of security incidents from corporate networks and remote endpoints.
Security researchers, enterprise software maker SAP, and the U.S. Cybersecurity and Infrastructure Security Agency (CISA) have issued warnings over a critical vulnerability affecting Internet Communication Manager (ICM), a core component of SAP business applications that enables HTTPS communications. Tracked as CVE-2022-22536, the vulnerability allows attackers to use malformed packets to trick SAP servers into exposing sensitive data without needing to authenticate, according to Onapsis Research Labs. A security patch is available and organizations are urged to update as soon as possible.
The HSE did not have a Chief Information Security Officer (CISO) or a “single responsible owner for cybersecurity at either senior executive or management level to provide leadership and direction.
It had no documented cyber incident response runbooks or IT recovery plans (apart from documented AD recovery plans) for recovering from a wide-scale ransomware event.
Under-resourced Information Security Managers were not performing their business as usual role (including a NIST-based cybersecurity review of systems) but were working on evaluating security controls for the COVID-19 vaccination system. Antivirus software triggered numerous alerts after detecting Cobalt Strike activity but these were not escalated. (The antivirus server was later encrypted in the attack).
There was no security monitoring capability that was able to effectively detect, investigate and respond to security alerts across HSE’s IT environment or the wider National Healthcare Network (NHN).
There was a lack of effective patching (updates, bug fixes etc.) across the IT estate and reliance was placed on a single antivirus product that was not monitored or effectively maintained with updates across the estate. (The initial workstation attacked had not had antivirus signatures updated for over a year.)
Over 30,000 machines were running Windows 7 (out of support since January 2020).
The initial breach came after a HSE staff member interacted with a malicious Microsoft Office Excel file attached to a phishing email; numerous subsequent alerts were not effectively investigated.
PwC’s crisp list of recommendations in the wake of the incident as well as detail on the business impact of the HSE ransomware attack may prove highly useful guidance on best practice for IT professionals looking to set up a security programme and get it funded.
