The BTK killer probably would have gotten away with it if he hadn't insisted on sending out communications, though there's also a chance that forensic genetic genealogy would have led to him eventually, as it did with Golden State Killer.

He sent a message asking whether they could track him if he sent in a floppy disk, and they said "no". (Specifically, he had prearranged that they put an ad in the paper with the words "Rex, it will be OK," if the answer was no.)

The floppy that he sent in had a single file, "TestA.rtf", which had no identifying metadata, but when the disk was run through EnCase, a digital investigation software, it showed that there was another file which had been "deleted". It was still present on the disk because a floppy drive doesn't (by default) write over deleted files, it just unallocated the space. That file was an agenda for a meeting at a church, and the metadata said the user who saved it was "Dennis", so they Googled the church name, found that the church president was Dennis Rader, drove by his house and saw the same car they already had on grainy video, tested crime scene DNA against his daughter's medical records, and that was basically it. The time from him sending the floppy to getting arrested was ten days.

So the police lied to him. It helped them to catch him, but this is now enshrined in serial killer lore, and I have to imagine that any aspiring serial killer like BTK will have read this account. I wonder if there was ever any consideration of the balance here. I've read some accounts that they "tricked" him, but I don't think that this rises to the level of trick, it was just a lie, albeit one that he set himself up for.

Part of the strategy with BTK was to stroke his considerable ego, to say that he was interesting, to get him to communicate more, hoping that he would slip up. This, too, is part of serial killer lore, and understanding of how serial killers work and how the police will attempt to catch them.

But as time stretches into the future, it seems like these tactics can only work once if the criminals in question are even remotely attempting to evade capture. Doesn't the "meta" evolve? The police will simply lie to you, so you can't trust any information from them. Do the police think this understanding is a net good? I kind of think it's not, especially since it seems like it torpedoes the other strategy of rapport and trust building.

I don't think they were wrong to lie, necessarily, but it does seem like a trick that you can't use too many times, at least not on those who are doing even a smidgen of research.

New perspective on supermassive black holes

Some of the first data from an international space mission is confirming decades worth of speculation about the galactic neighborhoods of supermassive black holes.

More exciting than the data, though, is the fact that the long-awaited satellite behind it—the X-Ray Imaging and Spectroscopy Mission or XRISM—is just getting started providing such unparalleled insights.

"We have found the right tool for developing an accurate picture of the unexplored orders of magnitude around supermassive black holes," Jon Miller, professor of astronomy at the University of Michigan, said of XRISM.

"We're beginning to see clues of what that environment really looks like."

The Japanese Aerospace Exploration Agency, or JAXA, which teamed up with NASA and the European Space Agency to create and launch XRISM, announced the new results, which were also published in The Astrophysical Journal Letters.

Miller was the lead author of that study. He and more than 100 co-authors from around the world investigated what's called an active galactic nucleus, which includes a supermassive black hole and its extreme surroundings.

To do this, they relied on XRISM's unparalleled ability to gather and measure spectra of X-rays emitted by cosmic phenomena.

"It is truly exciting that we are able to gather X-ray spectra with such unprecedented high resolution, particularly for the hottest plasmas in the universe," said Lia Corrales, U-M assistant professor of astronomy and a co-author of both XRISM publications.

"Spectra are so rich with information, we will surely be working to fully interpret the first datasets for many years to come."

Accretion disks with a twist

Space exploration enthusiasts may know that the Chandra X-ray Observatory—what NASA calls its flagship X-ray telescope—recently celebrated its 25th anniversary of operating in space.

What's less well known is that, over the past 25 years, an international cohort of scientists, engineers and space agency officials have been attempting to launch similarly sophisticated, but different X-ray missions. 

The goal of these attempts was to provide high-quality, complementary data to better understand what Chandra and other telescopes were seeing. XRISM is now delivering that data.

With their data set, Miller, Corrales and their colleagues have solidified a hypothesis about structures called accretion disks near supermassive black holes in active galactic nuclei.

These disks can be thought of like vinyl records made of gas and other loose particles from a galaxy being spun by the spectacular gravity of the black holes at their centers. By studying accretion disks, researchers can better understand what's happening around the black hole and how it impacts the lifecycle of its host galaxy.

By probing the center of a galaxy called NGC 4151, more than 50 million light years away, the XRISM collaboration confirmed that the disk's shape isn't as simple as once thought.

"What we're seeing is that the record isn't flat. It has a twist or a warp," Miller said. "It also appears to get thicker toward the outside."

Although suggestions of this more complex geometry have emerged in other data over the past two and a half decades, the XRISM results are the strongest direct evidence for it.

"We had hints," Miller said. "But somebody in forensics would say that we couldn't have convicted anyone with what we had."

The team also found that the accretion disk appears to be losing a lot of its gas. Again, scientists have theories about what happens to this material, but Miller said XRISM will enable researchers to find more definitive answers.

"It has been very hard to say what the fate of that gas is," he said. "Actually finding the direct evidence is the hard work that XRISM can do."

And XRISM isn't just allowing researchers to think about existing theories in new ways. It's enabling them to investigate parts of space that were invisible to them before.

The missing link

For all the talk of their gravitational pull being so strong that not even light can escape it, black holes are still responsible for creating a whole lot of electromagnetic radiation that we can detect.

For instance, the Event Horizon Telescope—a network of instruments on Earth sensitive to radiation emitted as radio waves—has enabled astronomers to zoom in and see the very edge of two different black holes.

There are other instruments on Earth and in space that detect different bands of radiation, including X-rays and infrared light, to provide larger, galaxy-scale views of the environs of black holes.

But scientists have lacked high-resolution tools to determine what was going on between those two scales, from right next to the black hole up to the size of its host galaxy. And that space between is where accretion disks and other interesting celestial structures exist.

If you were to divide the scale of the zoomed-out view of a black hole by that of its close-up, you'd get a number close to 100,000. To a physicist, each zero is an order of magnitude, meaning the gap in coverage spanned five orders of magnitude.

"When it comes to understanding how gas gets into a black hole, how some of that gas is lost and how the black hole impacts its host galaxy, it's those orders of magnitude that really matter," Miller said.

XRISM now gives researchers access to those scales by looking for X-rays emitted by iron around black hols and relying on the "S" in its acronym: spectroscopy. 

Rather than using X-ray light to construct an image, XRISM's spectroscopy instrument detects the energy of individual X-rays, or photons. Researchers can then see how many photons were detected with a particular energy across a range, or spectrum, of energies.

By collecting, studying and comparing spectra from different parts of the regions near a black hole, researchers are able to learn more about the processes afoot.

"We joke that spectra put the 'physics' in 'astrophysics,'" Miller said.

Although there are other operational X-ray spectroscopy tools, XRISM's is the most advanced and relies on a microcalorimeter, dubbed "Resolve." This turns the incident X-ray energy into heat rather than, say, a more conventional electrical signal.

"Resolve is allowing us to characterize the multi-structured and multi-temperature environment of supermassive black holes in a way that was not possible before," Corrales said.

XRISM provides researchers with 10 times better energy resolution compared with what they've had before, Miller said. Scientists have been waiting for an instrument like this for 25 years, but it hasn't been for a lack of trying.

If at first you don't succeed

Years before its 1999 launch, Chandra was initially conceived of as the Advanced X-Ray Astrophysics Facility, a single mission that would fly with state-of-the-art technology for both X-ray imaging and spectroscopy.

That, however, proved to be too expensive, so it was divided into the Chandra telescope and a spectroscopy mission called Astro-E, whose development was led by JAXA. Unfortunately, Astro-E was lost during its launch in February 2000.

JAXA, NASA and the European Space Agency all realized how important the tool was, Miller said, and worked together to essentially refly the Astro-E mission roughly five years later. This time, however, the mission was called Suzaku, named after a phoenix-like mythical bird.

"Suzaku made it into orbit, but its cryogenic system had a leak, so all its coolant leaked into space. Its prime scientific instrument never took actual data," Miller said. "There was a different camera on board for X-rays, though, and it did really nice work for about 10 years."

Within months of sunsetting Suzaku, the space agencies launched a third mission to provide the X-ray spectroscopy that the community was seeking. The mission took off as Astro-H in February 2016 and was renamed Hitomi after it entered orbit and deployed its solar panels.

Miller had traveled to Florida for a meeting about Hitomi right around the time disaster struck the mission. A maneuvering error sent Hitomi into an uncontrollable spin.

"It spun so fast that the solar panels flew off," Miller said. 

Less than 40 days after the launch, the space agencies lost contact with Hitomi.

"You could actually go out on the beach in Florida at night and watch it tumble across the sky," Miller said. "It flickered in a very unique way."

Before it ended, the Hitomi mission did manage to take what Miller quantified as one and a half scientific observations. That was enough to transform how researchers thought about galaxy clusters, which contain hundreds or thousands of galaxies, he said.

So it's fair to say that a lot was riding on XRISM when it launched in September 2023. Based on early returns, it sounds like XRISM is equipped to deliver. Miller and a handful of his global colleagues were among the first to see the data that would lead to their new report.

"It was very late in Japan, an odd time in Europe and we were all on Zoom. All of us had trouble finding the words," Miller said. "It was breathtaking."

Miller's original doctoral thesis project was meant to study data from the Astro-E mission, so he's been invested in this work for more than half his life and virtually his entire science career.

During that time, Hitomi and more successful missions like Chandra have been providing data that have enabled him and others in the field to further our understanding of the cosmos. But the researchers also knew they'd need something like the X-ray calorimeter on board XRISM to make the leaps they've been hungry for.

"It's been difficult at many points, but we kept getting hints about what might be possible," Miller said. "It's almost impossible to replicate these environments in earthbound experiments and we've been wanting to know a lot of the details of how they really work. I think we're finally going to make some progress on that."

I am always up for eldritch bats, tell me more

Hey, thanks for asking! Technically the concept goes, Bruce modifies himself -> it alters him in unexpected ways and brings him more in tune with the city.

Here's a snippet from the start of it:

Mission report. 

Bruce blinked past his concussion, laboriously typing up the events of the night, each finger aching as it moved on the keyboard. Bruce could feel scabs breaking off under the gloves, new blood binding the kevlar composite into his hands. 

Recently he'd realized that the reports needed to be started early, because he was prone to forgetting otherwise. 

His fractured hand moved clumsily over the keys, punching in letters describing the crime scene, his impressions, the evidence forensics had found. He frowned, struggling to recall exact numbers and deciding he could check footage later if needed. 

This was just a way to get his initial thoughts down, account for the limitations in the lenses. 

When the report was done, Bruce listed back against his chair, letting the chair support his back. A pressure headache tugged at his skull and Bruce knew he'd have to deal with the new spinal leak soon, but right now he didn't bother to move, the darkness of the Cave making the pain echo even more sharply through his bones and teeth. 

If he wanted to, Bruce could get up right now. He'd mastered every aspect of his body. Made torn muscles work, walked on broken bones. 

But the damage was particularly hard to ignore tonight. 

He’d long since stopped updating his own medical files, but he ran through an accounting of the present damage. Concussion, his second this week. Hand fracture, foot fracture, worsening labral tear in his hip. His injured jaw could barely move. He had a herniated disk, severe bruising.

HOW THEY GET AWAY W IT

-

Education purposes only.

There’s no for sure way of them successfully getting away but here’s some things that don’t work

1. Burying an animal on top to cover the scent

This won’t work since k9 are trained to smell the difference between human and animal

2. Planting endangered plants on top

Police will be able to search via warrant or simply digging around the plant

-

If the person wants to throw off pathologists they could try preserve the body via Freezing but not all the time that works. Pathologists can still determine most exterior causes and most interior. But determining the time is hard, time of deth isn’t exact and in these cases since the body is frozen most postmortem symptoms don’t show.

-

Another thing, the person is most likely to get caught unless there is no witnesses no dna and have no connection to the person.

But no dna is very hard unless you are a genius and even the smartest get lazy and get caught. How they try not to get dna in the scene is with gloves, different size shoes, hair nets, making sure the person did not scratch them since the dna is under their nails, no sea men, no spit or bite marks

FYI bite marks don’t always prove it

-

On the psychological side they have to be careful and NEVER make a mistake. One way it happened is with floppy disks (what dumbahh) or by getting too c0cky

-

As always pls kindly correct me on anything

Ok byeeee

Mandiant Finds UNC5820 FortiManager For Data Exfiltration

Mandiant and Fortinet worked together in October 2024 to look into the widespread abuse of FortiManager appliances across more than fifty potentially compromised FortiManager devices in a range of businesses. A threat actor can use an unauthorized, threat actor-controlled FortiManager device to run arbitrary code or commands against susceptible FortiManager devices with the vulnerability, CVE-2024-47575 / FG-IR-24-423.

As early as June 27, 2024, Mandiant saw a new threat cluster that is currently monitor as UNC5820 taking advantage of the FortiManager vulnerability. The configuration information of the FortiGate devices controlled by the compromised FortiManager was staged and exfiltrated by UNC5820. Along with the users and their FortiOS256-hashed passwords, this data includes comprehensive configuration details for the controlled equipment. UNC5820 might utilize this information to target the enterprise environment, advance laterally to the controlled Fortinet devices, and further attack the FortiManager.

The precise requests that the threat actor made in order to take advantage of the FortiManager vulnerability were not yet documented in the data sources that Mandiant examined. Furthermore, as of this point in Google cloud study, there is no proof that UNC5820 used the configuration data it had acquired to migrate laterally and endanger the environment even more. It therefore don’t have enough information at the time of publication to evaluate actor location or motivation. Mandiant will update this blog’s attribution assessment as new information emerges from investigations.

A forensic investigation should be carried out right away by any organizations whose FortiManager may be exposed to the internet.

Exploitation Details

The first known instance of Mandiant being exploited was on June 27, 2024. Several FortiManager devices were connected to the default port TCP/541 on that day via the IP address 45[.]32[.]41[.]202. Around the same time, the file system stored the staging of different Fortinet configuration files in an archive called /tmp/.tm that was compressed using Gzip. The files and folders mentioned in below Table were included in this bundle.FilenameDescription/var/dm/RCSFolder containing configuration files of managed FortiGate devices/var/dm/RCS/revinfo.dbDatabase containing additional information of the managed FortiGate devices/var/fds/data/devices.txtContains a list of FortiGate serials and their corresponding IP addresses/var/pm2/global.dbGlobal database that contains object configurations, policy packages, and header and footer sensor configuration for IPS/var/old_fmversionContains current FortiManager version, build, and branch information

Mandiant noticed a second attempt at exploitation using the same symptoms on September 23, 2024. Outgoing network traffic happened soon after the archive was created in both exploitation scenarios. The size of the archive is marginally less than the number of bytes delivered to the corresponding destination IP addresses. The specifics of this action are listed in below Table .

The threat actor’s device was linked to the targeted FortiManager during the second exploitation attempt. Figure shows the timestamp at which the illegal FortiManager was introduced to the Global Objects database.

The threat actor’s unknown Fortinet device showed up in the FortiManager console after they had successfully exploited the FortiManager.

The files /fds/data/subs.dat and /fds/data/subs.dat.tmp contain additional indicators of the exploitation that include an associated disposable email address and a company name as listed in Figure .SerialNumber=FMG-VMTM23017412|AccountID= 0qsc137p@justdefinition.com|Company=Purity Supreme|UserID=1756868

Lack of Follow-On Malicious Activity

Mandiant examined rootfs.gz, the device’s initramfs (RAM disk) that is mounted to /bin. During the period of exploitation activity, did not discover any malicious files that had been produced or altered.

Affected clients who displayed comparable activities in their environments were alerted by Google Cloud. In order to help identify Fortinet device exploit attempts, Google Cloud Threat Intelligence also conducted retrohunts while creating detections for this activity and manually escalated Pre-Release Detection Rule notifications to impacted SecOps customers.

Apart from working with Mandiant, Fortinet made aggressive efforts to notify its clients in advance of their advise so that they may improve their security posture before it was widely made public.

Mitigation Strategies / Workaround

Restrict only authorized internal IP addresses from accessing the FortiManager admin portal.

Permitted FortiGate addresses should be the only ones allowed to connect to FortiManager.

Deny FortiManager access to unidentified FortiGate devices.

Available 7.2.5, 7.0.12, 7.4.3 and later (not functional workaround on 7.6.0). config system global set fgfm-deny-unknown enable end

Tails OS

Have you ever traveled and succumbed to using a public computer that could be compromised and could potentially steal your data? Or even want to increase your privacy and anonymity against surveillance? The Tails operating system covers this. After doing some Tor browser surfing, I recently discovered Tails and decided to dig deeper into it and play around with it as I am always looking for new tools and protection measures, I can learn and use. Tails, or “The Amnesic Incognito Live System", is a security-focused Debian-based Linux distribution that connects to the internet only through the Tor network. works by routing internet traffic through a series of volunteer-operated servers called nodes or relays. Each user's data is encrypted multiple times and then sent through a randomly selected path of these nodes before reaching its final destination. At each node, one layer of encryption is removed, revealing only the next node in the path, like peeling layers of an onion, hence its logo and nickname.

Tail's most notable feature is its ability to boot from a USB or CD to turn any computer into a temporary” secure” machine by creating an almost ghost-like presence on the machine. When using Tails nothing is written to the hard disk and only runs from the memory on the computer. On top of this, Tails will actually overwrite the memory when exiting to prevent any cold boot attacks. Meaning, that once you shut down the OS all of your actions and information will be erased from memory. This is much more secure than just using incognito mode in your browser because that information could still be retrieved using computer forensics measures. Despite all this, Tails is not a hundred percent secure. There is still room for vulnerabilities like everything in the cyber realm and you do have the ability to sore data on the portable device to transfer between sessions and it is automatically encrypted, but this can be another vulnerability.

Fun fact: Tails it was used by Edward Snowden the ex-N NSA employee who leaked government secrets.

Digital forensics plays a crucial role in incident response, providing the means to identify, investigate, and mitigate cyber threats. This comprehensive guide explores how digital forensics is integrated into incident response, offering best practices and essential techniques to ensure effective and efficient handling of cyber incidents.

The Role of Digital Forensics in Incident Response

Digital forensics involves the collection, preservation, analysis, and presentation of digital evidence. In the context of incident response, it helps organizations:

1. **Identify the Incident**: Determine the nature and scope of the security breach.

2. **Contain the Threat**: Implement measures to prevent further damage.

3. **Eradicate the Cause**: Remove malicious code or access points.

4. **Recover Systems**: Restore affected systems to normal operation.

5. **Document Findings**: Provide a detailed account of the incident and the steps taken to resolve it.

Steps in computer forensics company for Incident Response

1. Preparation: Develop and implement an incident response plan that includes digital forensics procedures. Ensure that the team is trained and equipped with the necessary tools and resources.

2. Identification: Detect potential security incidents through monitoring and alert systems. Verify the incident by analyzing logs, network traffic, and system behavior.

3. Containment: Short-term containment involves isolating affected systems to prevent the spread of the attack. Long-term containment focuses on implementing temporary fixes while preparing for system recovery.

4. Eradication: Identify and eliminate the root cause of the incident. This may involve removing malware, closing vulnerabilities, and strengthening security measures.

5. Recovery: Restore and validate affected systems, ensuring they are free from malicious activity. Monitor the systems for any signs of residual issues.

6. **Lessons Learned**: Conduct a post-incident review to identify what went well and what needs improvement. Update the incident response plan and security policies based on the findings.

Techniques in Digital Forensics for Incident Response

1. Disk Imaging: Create exact copies of storage devices to preserve evidence. Analyze the copies to identify malicious files, hidden data, and other indicators of compromise.

2. Memory Forensics: Examine volatile memory (RAM) to uncover running processes, open network connections, and active malware that may not be present on the disk.

3. Log Analysis: Review logs from servers, firewalls, intrusion detection systems (IDS), and other network devices to trace the attacker's actions and identify affected systems.

4. Network Forensics: Capture and analyze network traffic to detect unauthorized communications, data exfiltration, and the use of command and control (C2) channels.

5. Malware Analysis: Disassemble and study malicious software to understand its behavior, functionality, and the techniques used by attackers.

Best Practices for Digital Forensics in Incident Response

1. Establish Clear Procedures: Develop standardized protocols for evidence collection, handling, and analysis. Ensure that all team members are familiar with these procedures.

2. Use Forensic Tools: Employ specialized forensic tools for data acquisition, analysis, and reporting. Popular tools include EnCase, FTK, and Volatility.

3. Maintain Chain of Custody: Document every step of evidence handling to preserve its integrity and admissibility in legal proceedings. Record who collected the evidence, when, and how it was stored.

4. Ensure Data Integrity: Use write-blockers during evidence acquisition to prevent data modification. Verify the integrity of collected evidence through hashing.

5. Collaborate with Legal Counsel: Work closely with legal experts to ensure compliance with relevant laws and regulations. Understand the legal implications of forensic activities and evidence handling.

6. Regular Training and Drills: Conduct regular training sessions and simulated incident response exercises to keep the team prepared and up-to-date with the latest techniques and threats.

Conclusion

Digital forensics is an integral part of incident response, providing the tools and techniques needed to identify, analyze, and resolve cyber incidents. By following best practices and maintaining a well-prepared incident response plan, organizations can effectively mitigate the impact of cyber threats and enhance their overall security posture. Understanding the role of digital forensics in incident response is crucial for any organization looking to protect its digital assets and ensure a swift recovery from cyber attacks.
