A new article is up: The Gentlemen: Inside the Ransomware Group Redefining Cybercrime. A closer look at how this crew blends branding, precision, and advanced evasion into a new model of ransomware.

The Gentlemen - Inside the Ransomware Group Redefining Cybercrime
The New Face of Digital Extortion In mid-2025, a ransomware group called The Gentlemen emerged with a level of sophistication that made cybersecurity professionals take notice. Unlike the chaotic "spr...

Hearing early, unconfirmed reports of a possible ransomware incident affecting a major behavior health provider. No public statement has been made yet, but I am monitoring for confirmation. Will be writing on this attack as soon as I have details available. #Cybersecurity #Healthcare #Ransomware

Tech Diplomacy starts with empathy. As security pros, we must meet clients where they are, not where we wish they were. SMBs are facing breaches at staggering rates—we must ask better questions and stay accessible to protect those who need it most. #Cybersecurity #SMB #InfoSec #Empathy #Security
The image shows two people shaking hands against a soft blue background filled with faint cloud shapes. On the left, a younger man with short dark blue hair and a navy shirt reaches out warmly. On the right, an older man with a white beard, glasses, and a blue suit smiles back, returning the handshake. Around them float minimalist blue icons symbolizing cybersecurity and connection: a shield with a checkmark, a heart with a checkmark, a dotted-line globe, and a laptop with a key on its screen. The tone is calm and collaborative, evoking empathy, trust, and digital diplomacy.

How feasible is iris-based MFA using a phone’s camera + AI? Instead of “something you have,” it becomes “something you are.” Curious what security folks think. #cybersecurity #MFA #biometrics

Gatekeeping is not knowledge management. New staff are not unskilled, they just lack the hidden context others keep in their heads. Instead of “you should know this,” give them tools and clear notes so they can succeed. We rise by sharing knowledge.

This is my theory: Auth abuse (like the F5 + Salesloft cases) triggered rushed identity hardening across the industry. Entra’s recent issues may be the growing pains. Tho if the security fixes break everything like this, can we really trust them?

Vendor OAuth is the hidden backdoor most orgs ignore. Salesloft-Drift proves incident response without systemic change fails. Monitoring + token discipline must become standard.

Cybersecurity isn’t failing from lack of tech — it’s failing from lack of maturity. My latest piece explores how MSPs could evolve from service delivery to capability building and reshape resilience itself.

The Maturity Divide: How Forward-Thinking MSPs Could Evolve
Cybersecurity isn't failing because of technology. It's failing because of organizational immaturity and because many leaders still view protection as an IT expense rather than a business foundation.

FYI for anyone seeing the cold takes about CISA “extending” F5 patch timelines — the directive calls the threat imminent and sets tight deadlines (Oct 22 & 31). No mention of shutdowns or staffing. Cyber defense roles are legally excepted — they can’t be furloughed or left unpaid.

#FYI #CISA #F5
malwarejake.bsky.social Jake Williams @malwarejake.bsky.social · 28d
The timelines in this CISA directive to patch F5 vulnerabilities are not grounded in the relative risk posed. The required remediation timelines have been artificially extended to ensure there's a possibility for compliance given staff impacted by the shutdowns.

Buying a home is now framed as a ‘savvy hack.’ People used to just… have homes. Instead of cheering how good we’ve become at being poor, maybe pay what we’re worth & build the housing you promised.

I'm a 28-year-old Gen Zer who bought an apartment in NYC. It was easier than I expected.
Like many other Gen Z homeowners, I bought my NYC apartment as a single buyer. Affordability is a major issue for Gen Z, but here's how I handled it.
