FortiGuard Labs is aware of a report that a new ransomware strain called Prestige was being distributed in an attack campaign targeting Ukraine and Poland. The ransomware encrypts files on a compromised machine and adds a “.enc” file extension to the affected files.Why is this Significant?This is significant because Prestige ransomware is one of the few ransomware strains being distributed to Ukraine, as well as Poland, who is a known ally of Ukraine.How Widespread is the Attack?According to Microsoft, Prestige ransomware was distributed to organizations in Ukraine and Poland.What is Prestige Ransomware?Prestige ransomware encrypts files on a compromised machine and adds a “.enc” file extension to the affected files.The ransomware leaves a ransom note in “README”, which asks the victim to contact the attacker by sending an email to the address for file decryption. The ransom note also has an unique ID, which acts as a victim identifier. It also deletes the shadow copies via vssadmin, which inhibits the victim’s ability to recover files.How was Prestige Ransomware Distributed?While the infection vector has not been identified, Microsoft reported that the attacker used several legitimate Windows and open-source tools for remote code execution, privilege execution and credential exfiltration prior to the ransomware deployment.What is the Status of Protection?FortiGuard Labs detects an available Prestige ransomware sample with the following AV coverage:• W32/Filecoder.OMM!tr.ransom
Several vulnerabilities were discovered in Squid, a fully featured web
proxy cache, which could result in exposure of sensitive information in
the cache manager (CVE-2022-41317),
or denial of service or information disclosure if Squid is configured to
negotiate authentication with the SSPI and SMB authentication helpers
(CVE-2022-41318).
Multiple security issues have been found in the Mozilla Firefox
web browser, which could potentially result in the execution
of arbitrary code or information disclosure.

CVE-2022-33748] (#2135263)
It was discovered that the SUNRPC RDMA protocol implementation in the Linux
kernel did not properly calculate the header size of a RPC message payload.
A local attacker could use this to expose sensitive information (kernel
memory). (CVE-2022-0812)
Moshe Kol, Amit Klein and Yossi Gilad discovered that the IP implementation
in the Linux kernel did not provide sufficient randomization when
calculating port offsets. An attacker could possibly use this to expose
sensitive information. (CVE-2022-1012, CVE-2022-32296)
Duoming Zhou discovered that race conditions existed in the timer handling
implementation of the Linux kernel’s Rose X.25 protocol layer, resulting in
use-after-free vulnerabilities. A local attacker could use this to cause a
denial of service (system crash). (CVE-2022-2318)
Roger Pau Monné discovered that the Xen virtual block driver in the Linux
kernel did not properly initialize memory pages to be used for shared
communication with the backend. A local attacker could use this to expose
sensitive information (guest kernel memory). (CVE-2022-26365)
Roger Pau Monné discovered that the Xen paravirtualization frontend in the
Linux kernel did not properly initialize memory pages to be used for shared
communication with the backend. A local attacker could use this to expose
sensitive information (guest kernel memory). (CVE-2022-33740)
It was discovered that the Xen paravirtualization frontend in the Linux
kernel incorrectly shared unrelated data when communicating with certain
backends. A local attacker could use this to cause a denial of service
(guest crash) or expose sensitive information (guest kernel memory).
(CVE-2022-33741, CVE-2022-33742)
Oleksandr Tyshchenko discovered that the Xen paravirtualization platform in
the Linux kernel on ARM platforms contained a race condition in certain
situations. An attacker in a guest VM could use this to cause a denial of
service in the host OS. (CVE-2022-33744)
Cory Snider discovered that Git incorrectly handled certain symbolic links.
An attacker could possibly use this issue to cause an unexpected behaviour.
(CVE-2022-39253)
Kevin Backhouse discovered that Git incorrectly handled certain command strings.
An attacker could possibly use this issue to arbitrary code execution.
