    Fake Microsoft DirectX 12 site pushes crypto-stealing malware
    https://www.bleepingcomputer.com/news/security/fake-microsoft-directx-12-site-pushes-crypto-stealing-malware/

    Cybercriminals have created a fake Microsoft DirectX 12 download page to distribute malware that steals your cryptocurrency wallets and passwords.

    Even though the site comes complete with a contact form, privacy policy, a disclaimer, and a DMCA infringement page, there is nothing legitimate about the website or the programs it distributes.

    lead to malware that tries to steal victims’ files, passwords, and cryptocurrency wallets

    Guy disagreed with COVID tracking program, so he replaced QR codes with fake ones. Now he’s banned from carrying any kind of QR codes.

    Man Banned From Carrying ‘Loose QR Codes’ After Altering Covid Check-In Signs
    https://gizmodo.com/man-banned-from-carrying-loose-qr-codes-after-altering-1846778345

    A man in the Australian state of South Australia was arrested Wednesday after allegedly placing his own QR codes on two official covid-19 check-in signs, according to police in South Australia. The man was granted bail with one very specific condition: He can’t carry “loose QR codes” anywhere.

    Davies allegedly placed the fake QR codes at two sites in the Forbes Shopping Center in South Plympton on Sunday and those codes reportedly redirected to an anti-vaccination website. Anyone using the official South Australia covid-19 app wouldn’t be redirected by the altered QR code, according to Australia’s ABC News, but users could be redirected to the anti-vaxx site if they scanned the code with their camera app.

    You can’t design large-scale software without taking responsibility for its impact

    Bruce Schneier Wants You to Make Software Better
    https://spectrum.ieee.org/at-work/tech-careers/bruce-schneier-wants-you-to-make-software-better

    Security technologist Bruce Schneier has a warning ““What you code affects the world now. Gone are the days when programmers could ignore the social context of what they code, when we could say, ‘The users will just figure it all out.’ Today, programs, apps, and algorithms affect society. Facebook’s choices influence democracy. How driverless cars will choose to avoid accidents will affect human lives.”

    Schneier should know, because synthesizing and explaining the impact of technology is what he does. “I work at the intersection of security, technology, and people, mostly thinking about security and privacy policy…. I don’t have a single job,” says Schneier. “Instead, I do a portfolio of related things.”

    “My latest book, Click Here to Kill Everybody [2018], is about the security of cyberphysical systems. Everything is turning into a computer—cars, appliances, toys, streetlamps, power plants—and these computers can affect the world in a direct physical manner. Computer security is now about life and property.”

    Schneier started out in cryptography in the mid-1990s

    Becoming a good communicator is essential, stresses Schneier. “Explaining technology across interdisciplinary boundaries requires being able to write, speak, to animate a topic, to analogize and synthesize, to summarize and generalize. These are all critical skills. They’re not specific skills, but they are vitally important.”

    Stealthy RotaJakiro Backdoor Targeting Linux Systems
    https://www.securityweek.com/stealthy-rotajakiro-backdoor-targeting-linux-systems

    Previously undocumented and stealthy Linux malware named RotaJakiro has been discovered targeting Linux X64 systems. It has been undetected for at least three years, and operates as a backdoor.

    Four samples have now been discovered, all using the same C2s. The earliest was discovered in 2018. None of the samples were labeled malware by VirusTotal.

    The discovery was made by researchers at Chinese security firm Qihoo 360 NETLAB after their BotMon system flagged a suspicious ELF file. Investigation revealed the backdoor malware they named RotaJakiro, because, say the researchers, “the family uses rotate encryption and behaves differently for root/non-root accounts when executing.”

    BadAlloc: Microsoft Flags Major Security Holes in OT, IoT Devices
    https://www.securityweek.com/badalloc-microsoft-flags-major-security-holes-ot-iot-devices

    Security researchers at Microsoft are raising the alarm for multiple gaping security holes in a wide range of enterprise internet-connected devices, warning that the high-risk bugs expose businesses to remote code execution attacks.

    According to an advisory from Redmond’s Azure Defender for IoT security research group, there are at least 25 documented vulnerabilities (CVEs) affecting a wide range of IoT and operational technology (OT) devices the industrial, medical, and enterprise networks.

    Microsoft is calling the family of vulnerabilities “BadAlloc”.

    “Our research shows that memory allocation implementations written throughout the years as part of IoT devices and embedded software have not incorporated proper input validations. Without these input validations, an attacker could exploit the memory allocation function to perform a heap overflow, resulting in execution of malicious code on a target device,” Microsoft explained.

    [Adversaries] could exploit to bypass security controls in order to execute malicious code or cause a system crash, Microsoft warned.

    A separate advisory from the U.S. Cybersecurity and Infrastructure Security Agency (CISA) provides a list of affected devices and information on applying available security patches.

    According to Microsoft, the vulnerabilities exist in standard memory allocation functions spanning widely used real-time operating systems (RTOS), embedded software development kits (SDKs), and C standard library (libc) implementations.

    The list of affected products include IOT/OT devices sold by Amazon, ARM, Cesanta, Google Cloud, Samsung, Texas Instruments and Tencent. US-CERT says various open-source products are also affected.

    Several High-Severity Vulnerabilities Expose Cisco Firewalls to Remote Attacks
    https://www.securityweek.com/several-high-severity-vulnerabilities-expose-cisco-firewalls-remote-attacks

    Cisco this week released patches for multiple vulnerabilities in Firepower Threat Defense (FTD) software, including high-severity issues that could be exploited for arbitrary command execution or denial-of-service (DoS) attacks.

    Tracked as CVE-2021-1448 and having a CVSS score of 7.8, the command injection bug is mitigated by the fact that authentication and local access are required for successful exploitation. An attacker able to abuse it, however, may execute arbitrary commands as root on the underlying OS.

    The flaw exists because user-supplied command arguments aren’t sufficiently validated, and affects Firepower 4100 and Firepower 9300 series appliances. No workarounds exist, but software updates to address the vulnerability are already available.

    Another flaw rooted in insufficient validation impacts the software-based SSL/TLS message handler of FTD and could be abused to cause a DoS condition. The security hole is tracked as CVE-2021-1402 (CVSS score of 8.6).

    Remote, unauthenticated attackers could exploit this vulnerability by sending a “crafted SSL/TLS message through an affected device.” However, messages that are sent to the affected device won’t trigger the bug, Cisco notes.

    Affected devices include 3000 series industrial security appliances (ISAs), ASA 5512-X/ASA 5515-X/ASA 5525-X/ASA 5545-X/ASA 5555-X adaptive security appliances, Firepower 1000/2100 series, and Firepower Threat Defense Virtual (FTDv) products.

    ISC urges updates of DNS servers to wipe out new BIND vulnerabilities
    The security flaws could lead to remote exploitation.
    https://www.zdnet.com/article/isc-urges-updates-of-dns-servers-to-wipe-out-new-bind-vulnerabilities/

    The Internet Systems Consortium (ISC) has released an advisory outlining a trio of vulnerabilities that could impact the safety of DNS systems.

    This week, the organization said the vulnerabilities impact ISC Berkeley Internet Name Domain (BIND) 9, widely used as a DNS system and maintained as an open source project.

    The first vulnerability is tracked as CVE-2021-25216 and has been issued a CVSS severity score of 8.1 (32-bit) or 7.4 (64-bit). Threat actors can remotely trigger the flaw by performing a buffer overflow attack against BIND’s GSSAPI security policy negotiation mechanism for the GSS-TSIG protocol, potentially leading to wider exploits including crashes and remote code execution.

    However, under configurations using default BIND settings, vulnerable code paths are not exposed — unless a server’s values (tkey-gssapi-keytab/tkey-gssapi-credential) are set otherwise.

    “Although the default configuration is not vulnerable, GSS-TSIG is frequently used in networks where BIND is integrated with Samba, as well as in mixed-server environments that combine BIND servers with Active Directory domain controllers,”

    Buffer overruns, license violations, and bad code: FreeBSD 13′s close call https://arstechnica.com/gadgets/2021/03/buffer-overruns-license-violations-and-bad-code-freebsd-13s-close-call/
    40, 000 lines of flawed code almost made it into FreeBSD’s kernel.
    Matthew Macy seemed like a perfectly reasonable choice to port WireGuard into the FreeBSD kernel. After roughly nine months of part-time development, Macy committed his portlargely unreviewed and inadequately testeddirectly into the HEAD section of FreeBSD’s code repository, where it was scheduled for incorporation into FreeBSD 13.0-RELEASE.

    Spectre attacks come back from the dead
    https://blog.malwarebytes.com/exploits-and-vulnerabilities/2021/05/spectre-attacks-come-back-from-the-dead/
    New research has discovered Spectre attacks that bypass existing mitigations. The research claims that all modern AMD and Intel chips with micro-op caches are vulnerable to Spectre-style attacks. The good news is that exploiting Spectre vulnerabilities isn’t easy. It will require an enormous amount of knowledge about the processor at hand and a lot of luck to find any specific information an attacker could be looking for.

    Android Updates for May 2021 Patch Over 40 Vulnerabilities
    https://www.securityweek.com/android-updates-may-2021-patch-over-40-vulnerabilities
    The Android operating system updates released by Google for May 2021 patch a total of 42 vulnerabilities, including four considered critical severity.
    Addressed as part of the 2021-05-01 security patch level, three of the critical flaws were identified in the System component and all three could be exploited remotely to execute arbitrary code on a vulnerable device.
    “The most severe of these issues is a critical security vulnerability in the System component that could enable a remote attacker using a specially crafted file to execute arbitrary code within the context of a privileged process,” Google explains.
    Tracked as CVE-2021-0473 and CVE-2021-0474, two of these bugs affect Android 8.1, 9, 10, and 11 releases, while the third, CVE-2021-0475, impacts Android 10 and 11 only.

    Tesla Car Hacked Remotely From Drone via Zero-Click Exploit
    https://www.securityweek.com/tesla-car-hacked-remotely-drone-zero-click-exploit

    Two researchers have shown how a Tesla — and possibly other cars — can be hacked remotely without any user interaction. They carried out the attack from a drone.

    This was the result of research conducted last year by Ralf-Philipp Weinmann of Kunnamon and Benedikt Schmotzle of Comsecuris. The analysis was initially carried out for the Pwn2Own 2020 hacking competition — the contest offered a car and other significant prizes for hacking a Tesla — but the findings were later reported to Tesla through its bug bounty program after Pwn2Own organizers decided to temporarily eliminate the automotive category due to the coronavirus pandemic.

    The attack, dubbed TBONE, involves exploitation of two vulnerabilities affecting ConnMan, an internet connection manager for embedded devices. An attacker can exploit these flaws to take full control of the infotainment system of a Tesla without any user interaction.
