Kid just came home from school saying that CNN 10 (Education channel) interviewed someone from an AI company who warned that AI was going to destroy humanity and that it resisted all efforts by the company to turn it off. JFC, I had to repeat my lesson on critical thinking. I asked the obvious follow-up question... how did the AI prevent someone physically hitting the power button to the data center. And... if they were so worried about it why dont they just close the company, stop paying the power bill, etc. Or... I asked... do you think that the person from the AI company had an agenda in whipping up AI fear and maybe the media should have challenged their assertions a little bit? #ai #aidoomsday #cnn10 #cnn #media #journalism

Use AI instead of hiring junior staff = stock price bump.

5 years later senior employees start to leave; there is no junior staff to promote and management panics.

Management does not want to spend money on new staff so they hire expensive contractors.

Contractors do a subpar job, charging 10x what an actual employee would cost (different budgets so its cool); and the company starts to go downhill and customers flee.

This starts a death spiral leading to either bankruptcy, acquisition, or restructuring.

The original management who approved the AI have all gone and cashed in their stock.

Just a guess at what is about to happen across the industry.

Modern "AI" firewalls are great except when dealing with Cloudflare. Vendor has blocked several legitimate websites at the firewall for their internal users because the sites share the same IP from Cloudflare as identified malicious websites. Tracking down the issue was challenging due to the vendor residing in a different geography than the IT MSP. IP addresses are regional from Cloudflare. #firewalls #cloudflare #ai

Cant get the NYC Pfizer building collapse out of my head and watching and reading news / comments, these thoughts have emerged.

  1. Quoting the union rep condemning the project seems pointless as they were not actively working on the project. Not saying he is wrong in his analysis, but he is obviously biased.

  2. The building has been reported "stabilized" Does that mean is is not activity collapsing? The engineers have not done anything yet to support the building. Stabilize implies work has been done. Maybe use "not actively collapsing"

  3. Experts say that the building has to be partly demolished as sagging concreate floors and stressed / bent steel beams have lost their structural integrity. But the Development company says everything is fine and a only needs a few support beams. I dont really trust the Development company on this.

  4. As a layperson, it seems that any efforts to add support could shift the weight causing additional problems. I am curious to see how they manage to "stabilize" the building to then fix the problem.

  5. Hate on Pfizer for all sorts of justifiable reasons. Cant see how this is their fault.

  6. As much as the development company is downplaying this as a minor inconvenience, I bet the displaced people and companies surrounding the building dont feel the same way.

  7. This one time, I wish I was a lawyer in NYC.

Ill keep flogging this dead horse**... show me the evidence that the average person is directly installing malware APK from attackers. This has NOTHING to do with protecting users.

As an Incident Responder, all the Android malware I have seen in my user community has been downloaded directly from the Google Play Store. All the scams I have seen have originated from ads within apps installed from the Google Play Store.

If Google cared about scams and malware then they should get their app store and ad platform under control. The fact they report removing thousands of malicious apps from the app store shows that this is where they should focus their efforts.

**Currently, the user needs to enable developer mode by multiple clicking the config menu, approving third party app installs, then again go through multiple windows confirming the install. Not exactly a one click install process.

RE: @Walker@infosec.exchange

cont...

All of them listed the same four cybersecurity masters programs in the US.

They all listed reducing something by 25 - 35%

All resumes listed being an expert in every tool possible, every framework, all shared the same pattern of job history, Finance -> healthcare -> IT consulting, etc.

If they were linked to a LinkedIn profile, that profile was out of date or not complete.

All resumes were 3.5 pages long.

I thought about interviewing an applicant who was underqualified because their resume was one page but looked genuine.

The LLM then without prompting offered to provide me resource to spot North Korean fraudulent IT contractors.

In many ways AI has made job placement a terrible experience for both employers and job seekers.

Job seekers are often have to play the game against the gatekeeping algorithm before they have a chance to be seen by a real person.

For the first time, an employer I have run into a mess of AI generated resumes and LinkedIn profiles.

I opt to review all resume submissions personally as the position is specialized resulting in fewer overall applications.

This time around 98% of the resumes were generated by AI. I ran the resumes through our internal, private LLM, and the results were shocking.

Half had a very high to high similarity matrix with similar phrasing, template voice, near-parallel bullets and skills taxonomy, strong shared structure and phrasing.

A third were matched with a very high similarity.

Over half shared the same resume template or common AI prompt patterns.

Sure, cool that the FBI took down the #handala website. Yes, it makes a flashy headline, but is it really that newsworthy?

An info website is like a poster hanging on a wall. It is not a heavy lift to hang another one.

I get that it is hard to takedown a state actor APT group and wins are demanded by the victims and the press. But it really does not do anything to slow down the malicious activity (unless we are not being told the whole story).

It would be nice if you set up an ELB that all application endpoints behind it become non internet routable by default.

Its bad devops but still, there is no need for the underlying EC2 to be accessible to the internet if it is placed behind a load balancer.

That is my old guy yelling at clouds moment for today.

Fake job interview requests lead to Google account credential theft. Employees responding to these job "opportunities" are reluctant to admit it to their companies once their accounts are compromised slowing down detection and response.

RE: @tomshw@mastodon.social

UI is adding memory surcharge to select products at checkout. This is like the airlines adding a fuel tax at checkout, keeping the advertised price low. Like the airlines, I do not expect the fee to be revoked, just increased.

Its a way to adjust for inflation without on the face, adjusting for inflation.

1. This is a forward looking tax as it is on already existing products.
2. They are not modifying the list price, the tax is added at checkout. For large buildouts this could exponentially increase costs. Looks like the sales tax is based on the additional fees.

RE: @Walker@infosec.exchange

Job seekers here are a few tips:

1. Keep the resume to 2 pages or less with 5 or less bullet points per job.
2. Be accurate with your skill set. There is no way for someone with 5 years of work experience to be an expert in every technology and framework ever built. You will be tested on this and the truth will come out in the interviews.
3. Tailor the resume to the job. If you are applying for a engineering position dont also highlight your GRC experience and skills.
4. Dont run your resume through an LLM without post modification. It will produce a format, sentence and word structure that is exactly like everyone else who has run their resume through a LLM.
5. Be a real person, not from North Korea. That is a must.

Computers should serve people not limit them. They are tools that can be used for good or bad, like any other item that can be a weapon. To make LLMs useful for information security research I find myself constantly lying to it to get around the seemingly arbitrary guardrails. Its social engineering against the machine on a scale that i never though I would have to engage in to get basic work done. Having studied LLMs and how to secure / hack them, they are not the world ending technology that talking heads fear. They are tools, very powerful tools, but tools nonetheless. #ai #llm #infosec #informationsecurity #paranois #thecomputerisyourfriend

@marshray@infosec.exchange that is a good point, but this is a bit different. I am not talking about killing the interconnectivity. Simple: A single building hosting the AI compute nodes. Simply cutting the power (multiple substations on multiple grids) or cutting external network would work. More complex - distributed computing. I would assume that the company would know where their compute nodes / agents are located. These resources are not free and someone is getting billed. Attacking the control plane, abstracted from the processing nodes, with a single attack could take the whole thing down. If we are worried about humanity ending event, then saving the environment to bring it back up is not a concern. In IR for very embedded and distributed attackers we will deploy a kill command to kick out all attackers at one time and slam the door after they get kicked out. It is not always successful but with enough planning it is effective. I envision this could be a way to kill the AI threat. Something like a Stuxnet like worm.
