🚨 Two US cybersecurity professionals have been sentenced for moonlighting as ALPHV BlackCat ransomware affiliates.

Ryan Goldberg, 40, of Georgia, and Kevin Martin, 36, of Texas, deployed BlackCat ransomware against multiple US victims between April and December 2023. They paid the operators a 20% cut for access to the platform, hit medical and engineering firms, leaked patient data to pressure payment, and split a $1.2 million Bitcoin ransom three ways with co-conspirator Angelo Martino.

Martino had a second job. He worked as a ransomware negotiator for victims, and used that role to leak confidential victim information to the attackers to push ransom prices up.

When Goldberg tried to flee abroad, the FBI tracked him through 10 countries before he was caught.

Both men were sentenced yesterday. Martino is sentenced July 9.

β—οΈπŸ‡ΊπŸ‡¦ GTA V is being used to train drone operators. Ukraine's Ministry of Defense drone school WeTrueGun has turned GTA V into a working FPV drone simulator. Soldiers say it feels "surprisingly close" to a real setup.

WeTrueGun is one of the most serious FPV training operations in Ukraine. The school trains future Armed Forces pilots to become UAV operators, is officially accredited by Ukraine's Ministry of Defense, and runs a 35-37 day course covering 340 academic hours: drone assembly, programming, tactical theory, electronic warfare countermeasures, situational-awareness systems like Kropyva and Delta, aviation meteorology, and live-fire flight training on targets.

The team built an FPV simulator inside GTA V's open world. Pilots can connect a real radio controller (the Radiomaster TX16S MK3 in the demo), fly anywhere on the massive map, design their own missions, and tune the simulated drone to match the response of their real rig. The mod even includes thermal vision modes.

Why GTA V instead of a dedicated simulator:

πŸ”΄ The map is enormous and unrestricted, no arbitrary boundaries
πŸ”΄ Dense urban terrain, moving vehicles, and pedestrian targets mirror real combat scenarios
πŸ”΄ No software gating, mission scripts, or canned scenarios
πŸ”΄ Pilots can practice tracking moving targets through complex environments

WeTrueGun is clear that GTA V is not a replacement for actual training. The GTA V build is for keeping fingers sharp between sessions, experimenting with mission design, and lowering the barrier for new recruits.

🚨 BREAKING: GTFO ICE, the new anti-ICE "rapid response network" launched by ex-DHS Chief of Staff Miles Taylor, has allegedly exposed 17,662 users' names, emails, phones, and ZIPs on a public API.

The exposed data was sent to law enforcement agencies by the people who found it. They are now sending the following email to everyone who was exposed on the list.

❗️ Why the GTFO ICE breach matters beyond the open API:

πŸ”΄ 17,662 anti-ICE signups reportedly handed to FBI, ICE, HSI by the researchers
πŸ”΄ Affected users were not notified by the operator(s) first
πŸ”΄ No allegation of user crime, no GDPR-style breach process
πŸ”΄ This inverts responsible disclosure into political targeting

β€ΌοΈπŸš¨ NEW RESEARCH: Fiber-optic cables can be turned into a hidden microphone and used for eavesdropping.

Researchers from Hong Kong's PolyU and CUHK just proved it works in real conditions. The paper was presented at NDSS 2026, one of the top cybersecurity conferences in the world.

When someone talks in a room, the sound waves cause tiny vibrations in everything around them, including the thin glass fiber that runs into your apartment from your internet provider. Those vibrations slightly disturb the laser light traveling through the cable. If an attacker plugs the other end of that cable into a special device called a Distributed Acoustic Sensing system, they can read those tiny disturbances and turn them back into recognizable speech.

The problem for the attacker: a normal fiber lying along your baseboard is not sensitive enough on its own. Sound fades too fast in the air, and the fiber is too thin to pick it up.

So the researchers built a small device they call a "Sensory Receptor." It is basically a 65mm plastic cylinder with about 15 meters of fiber wound around it. The cylinder catches and amplifies sound waves enough for the fiber to register them. Crucially, it is small enough to hide inside the same little plastic junction box your internet installer leaves on the wall to manage extra cable.

What the attack can actually pick up:

πŸ”΄ Daily activities (typing, walking, snoring, washing dishes): 83% recognition accuracy
πŸ”΄ Where in the room a sound is coming from: accurate to within about one meter
πŸ”΄ Spoken words at meters from the receptor
πŸ”΄ In a real office test, with the receptor hidden in a fiber box and the attacker 50+ meters away in another room, around 80% of the conversation was recoverable

Why this attack is different from a hidden microphone:

πŸ”΄ No electricity, no batteries, no radio signals
πŸ”΄ Cannot be found by professional bug sweeps that look for hidden mics or cameras
πŸ”΄ Cannot be jammed by ultrasonic jammers (the kind some boardrooms use against phone microphones)
πŸ”΄ Looks identical to a normal fiber cable

The researchers tested a commercial ultrasonic jammer right next to their device and it had zero effect. The defenses meant to protect sensitive meetings simply do not see this attack coming.

What you can do:

πŸ”΄ If you run a sensitive office or meeting room, ask your IT team about polished fiber connectors and optical isolators. Both make this attack much harder.
πŸ”΄ Do not let your internet installer leave excess fiber coiled up inside the room. Have them coil it inside the wall or in a sealed box outside the room.
πŸ”΄ Keep fiber cable runs away from desks and walls that resonate with conversation.
πŸ”΄ In high-security spaces, soundproof the walls and ceilings where fiber runs.

πŸ‡¬πŸ‡§ The first major assessment of the UK's Online Safety Act is out. Turns out kids are fooling the age checks by drawing moustaches on their faces.

"I did catch my son using an eyebrow pencil to draw a moustache on his face, and it verified him as 15 years old." Mum of a 12-year-old, in a new report from Internet Matters, the UK's leading online-safety NGO.

That single line tells you almost everything you need to know about how the UK's Online Safety Act is going.

This is the law that:
πŸ”΄ Forced UK platforms to demand government IDs, facial scans, and credit-card checks from adults to access ordinary websites
πŸ”΄ Drove a 1,800%+ spike in VPN downloads the week the porn-site age checks went live in July 2025
πŸ”΄ Pushed millions of users into handing biometric data to private third-party verification vendors
πŸ”΄ Sits at the front of a global wave: Greece's anonymity ban, France's "VPNs are next" comments, Utah's VPN crackdown, and the EU's 27-state rollout deadline of December 2026

The headline numbers from the assessment:
πŸ”΄ 46% of children say age checks are easy to bypass. Only 17% say they are difficult.
πŸ”΄ 32% of children have already bypassed them in the past two months
πŸ”΄ 49% of children still report experiencing harm online in the past month

The bypass methods kids reported, in their own words:
πŸ”΄ Drawing on facial hair with eyebrow pencil to fool facial age estimation
πŸ”΄ Holding up a video game character's head turning during the face-scan
πŸ”΄ Submitting a video of a different person's face entirely
πŸ”΄ Using a parent's ID (often with parental consent)
πŸ”΄ Entering a fake birthday (still works on most platforms)
πŸ”΄ Using someone else's login or device
πŸ”΄ In a small minority of cases, VPNs

One 12-year-old girl explained the system to researchers: "Every time I go live on TikTok, it tells me I have to be 18, but when the AI detects that I'm not 18 they ban me. But they only ban me for 10 minutes and then I can go live again." That is the entire enforcement model.

A 14-year-old summed up the broader picture: "It's not practical because the more you restrict it, the more people are going to want to get past that age restriction." A 16-year-old, more bluntly: "I think it's a great idea in theory and I applaud its intentions, but I don't see how that's feasible, because kids will always find a way."

Even when verification works, it works against the children. A 12-year-old boy on Roblox: "I put my face in and I got 15 when I'm 12, so I'm chatting with people older than me when I shouldn't be." A 13-year-old non-binary child: "Adults can very easily use a face they searched on the internet to trick it into thinking you're someone you're not, so there might be adults in kids' age groups trying to groom them." Recent reporting confirms exactly that. Underage Roblox accounts are now being sold online to predators precisely because they bypass the new "safety" measures.

One detail in the report stops you cold. Multiple children described being unintentionally exposed through their feeds to the assassination of Charlie Kirk. A 14-year-old: "I saw it on Snapchat. I broke down into tears and then told my mum immediately." Violent content, racist content, content promoting unrealistic body types: all explicitly prohibited under the Children's Safety Codes. All still landing in feeds at scale.
