” The researchers noticed that the attack targeted firmware versions of devices ranging between 7.0.14 In the reconnaissance phase, experts observed automated login/logout events without changes until November 22, 2024, when unauthorized configuration edits began. Targeting appeared opportunistic rather than targeted.
The resulting tool’s capabilities include modifying operating system kernel structures to disable notification routines, for example, about a process creation event in the system or a load event. This is a utility driver used to update PC drivers, BIOS and firmware.
With time, the vulnerabilities were patched, and restrictions were added to the firmware. Attackers are leveraging this by embedding malicious software into Android device firmware. Attackers are now embedding a sophisticated multi-stage loader directly into device firmware. oat ) located in the same directory.
Firmware The MMB runs on Linux, and its filesystems are located on the eMMC. Custom IPC Inside the head unit, firmware services use custom IPC protocols for communication between their own threads, other services and other ECUs. Its main distinctive feature is that thriftme allows subscribers to be notified about particular events.
Minimal Event Logging and Alerting Capabilities Some Embedded Systems often lack the capability to collect and collate event logs to a centralised location for SOC analysis. Figure 2: Dual-homed GPS timeserver Additionally, the firmware version installed on the GPS timeserver was outdated with several known vulnerabilities.
Antoine Cauchois highlights multiple strategies for defenders: Monitor Event ID 5145 (file access to SYSVOL) and 4688 (process creation). GUID hijacking: Replace the DLL path of a legitimate but unused built-in CSE, allowing attackers to use a “trusted” GUID to load malicious code.
In another case, a medical device manufacturer's firmware update system was targeted; malware was inserted into life-saving equipment (like pacemakers and insulin pumps), raising alarms about physical safety. Practicing joint response will make real events far less chaotic. Each device can be a new weak link if not secured.
It was a rare and notable event to observe a Linux ELF application being used to try to spread malware across platforms to Windows computers. Successful exploitation of these vulnerabilities could allow attackers to steal sensitive data, inject firmware payloads, and even reach LAN-connected devices. concludes the report.
We then found a function with a list of all supported command names (event names) and reverse engineered how they are obfuscated. By the time we analyzed the attack, the attackers had already removed the exploit from the decoy website, preventing us from easily obtaining the next stage of the attack.
A continuation of the events stemming from UK giving a secret order to Apple to incorporate backdoors for iCloud , regardless of whether ADP was enabled.

The state-sponsored hackers was observed using a custom firmware backdoor which was enabled and disabled by sending specially crafted TCP or UDP packets to the devices.
But just days before the event Western Digital released MyCloud OS 5 , which eliminated the bug they found. That update effectively nullified their chances at competing in Pwn2Own, which requires exploits to work against the latest firmware or software supported by the targeted device.
At the end of 2021, we were made aware of a UEFI firmware-level compromise through logs from our Firmware Scanner , which has been integrated into Kaspersky products since the beginning of 2019. This one is made up of implants found in the UEFI firmware within the SPI flash, a non-volatile storage external to the hard drive.
As a rule, this means that the source code of the device’s firmware is unavailable and all the researcher can use is the user manual and a few threads on some user forum discussing the device’s operation. The vulnerability assessment of IoT/IIoT devices is based on analyzing their firmware.
” Rapid7 ‘s Caitlin Condon called this remarkable turn of events “fairly stunning,” and said there appear to be roughly 11,000 vulnerable ESG devices still connected to the Internet worldwide. “Barracuda’s recommendation at this time is full replacement of the impacted ESG.”
I also looked at custom firmware and soldering and why, to my mind, that was a path I didn't need to go down at this time. Let's got through the options: Firmware Patching I'll start with the devices themselves and pose a question to you: can you remember the last time you patched the firmware in your light globes? Or vibrator.
Then there are firmware developers, transport agencies, testing facilities, and security evaluation agencies that handle the device before it is sent to the corporate client. This complexity can be compounded by the effects of world events like COVID-19 or a war, resulting in manufacturing slowdowns and lockdowns.
New Firmware Flaws Resurrect Cold Boot Attacks. A team of security researchers demonstrated that the firmware running on nearly all modern computers is vulnerable to cold boot attacks. Planning for these events is a better practice than assuming devices cannot be physically compromised by hackers because that’s obviously not the case.”
The malware was likely deployed in 2021, and was able to persist on the appliances tenaciously, even surviving firmware upgrades. The malware checked for the presence of a firmware upgrade every ten seconds. The malware was able to steal user credentials and provide shell access.
I'm not intentionally pushing these out later than usual, but events have just been such over the last few weeks that it's worked out that way. This one really is a short one though as there hasn't been a lot of newsworthy stuff going on this week, other than the new Instamics I picked up which are rather cool.
North Korea-linked Lazarus APT has been spotted deploying a Windows rootkit by taking advantage of an exploit in a Dell firmware driver. The North Korea-backed Lazarus Group has been observed deploying a Windows rootkit by relying on exploit in a Dell firmware driver dbutil_2_3.sys, sys, ESET researchers warn. Pierluigi Paganini.
Download the PDF > In the wake of the Sunburst attack, IR and threat hunting are more important than ever, and firmware should be a key part of these efforts.

A useful exercise in that regard is to try to foresee the future trends and significant events that might be coming in the near future. Verdict: some incidents, but no major event ❌ Private sector supporting an influx of new APT players. Verdict: prediction partially fulfilled 🆗 (more cases, no major event).
“Thus, it is implemented as a UEFI/BIOS module, able to survive such events. This solution comes pre-installed in the firmware of a large number of laptops manufactured by various OEMs, waiting to be activated by their owners.” The only way to remove the malware is reflashing the UEFI firmware.
From the perspective of incident handling and incident response, well-synchronized time across systems facilitates log analysis, forensic activities and correlation of events. Many GPS-enabled devices that were not properly designed to account for the rollover event exhibited problems on that date. Even worse is getting shut out.
