Russian cybersecurity firm owner convicted of $90 million SEC earning reports hack
Read Time:26 Second
The owner of a Russian penetration-testing company has been found guilty of being part of an elaborate scheme that netted $90 million after stealing SEC earning reports.
For nearly three years, 42-year-old Vladislav Klyushin – the owner of Moscow-based cybersecurity firm M-13 – and his co-conspirators had hacked into two US-based filing agents used by publicly-traded American companies to file earning reports to the Securities and Exchange Commission.

USN-5879-1: Linux kernel (HWE) vulnerabilities
Read Time:1 Minute, 51 Second
Kyle Zeng discovered that the sysctl implementation in the Linux kernel
contained a stack-based buffer overflow. A local attacker could use this to
cause a denial of service (system crash) or execute arbitrary code.
(CVE-2022-4378)
Tamás Koczka discovered that the Bluetooth L2CAP handshake implementation
in the Linux kernel contained multiple use-after-free vulnerabilities. A
physically proximate attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2022-42896)
It was discovered that the Bluetooth HCI implementation in the Linux kernel
did not properly deallocate memory in some situations. An attacker could
possibly use this cause a denial of service (memory exhaustion).
(CVE-2022-3619)
It was discovered that the Broadcom FullMAC USB WiFi driver in the Linux
kernel did not properly perform bounds checking in some situations. A
physically proximate attacker could use this to craft a malicious USB
device that when inserted, could cause a denial of service (system crash)
or possibly execute arbitrary code. (CVE-2022-3628)
It was discovered that a use-after-free vulnerability existed in the
Bluetooth stack in the Linux kernel. A local attacker could use this to
cause a denial of service (system crash) or possibly execute arbitrary
code. (CVE-2022-3640)
It was discovered that the Xen netback driver in the Linux kernel did not
properly handle packets structured in certain ways. An attacker in a guest
VM could possibly use this to cause a denial of service (host NIC
availability). (CVE-2022-3643)
Tamás Koczka discovered that the Bluetooth L2CAP implementation in the
Linux kernel did not properly initialize memory in some situations. A
physically proximate attacker could possibly use this to expose sensitive
information (kernel memory). (CVE-2022-42895)
It was discovered that an integer overflow vulnerability existed in the
Bluetooth subsystem in the Linux kernel. A physically proximate attacker
could use this to cause a denial of service (system crash).
(CVE-2022-45934)
It was discovered that a race condition existed in the qdisc implementation
in the Linux kernel, leading to a use-after-free vulnerability. A local
attacker could use this to cause a denial of service (system crash) or
possibly execute arbitrary code. (CVE-2023-0590)

Evolving cyberattacks, alert fatigue creating DFIR burnout, regulatory risk
Read Time:33 Second
The evolution of cybercrime is weighing heavily on digital forensics and incident response (DFIR) teams, leading to significant burnout and potential regulatory risk. That’s according to the 2023 State of Enterprise DFIR survey by Magnet Forensics, a developer of digital investigation solutions.
The firm surveyed 492 DFIR professionals in North America and Europe, the Middle East, and Africa working in organizations in industries such as technology, manufacturing, government, telecommunications, and healthcare. Respondents described the current cybercrime landscape as one that is evolving beyond ransomware and taking a toll on their ability to investigate threats and incidents, Magnet Forensics said.

USN-5778-1 fixed several vulnerabilities in X.Org. This update provides
the corresponding update for Ubuntu 14.04 ESM and Ubuntu 16.04 ESM.
Original advisory details:
Jan-Niklas Sohn discovered that X.Org X Server extensions contained
multiple security issues. An attacker could possibly use these issues to
cause the X Server to crash, execute arbitrary code, or escalate
privileges.

ChatGPT Is Ingesting Corporate Secrets
Read Time:35 Second
According to internal Slack messages that were leaked to Insider, an Amazon lawyer told workers that they had “already seen instances” of text generated by ChatGPT that “closely” resembled internal company data.
This issue seems to have come to a head recently because Amazon staffers and other tech workers throughout the industry have begun using ChatGPT as a “coding assistant” of sorts to help them write or improve strings of code, the report notes.
[…]
“This is important because your inputs may be used as training data for a further iteration of ChatGPT,” the lawyer wrote in the Slack messages viewed by Insider, “and we wouldn’t want its output to include or resemble our confidential information.”
