The FBI has been using push alerts to track down predators.

The Washington Post describes how law enforcers have gotten companies like Google to hand over data associated with push notifications. Investigators use the code to track down child predators, even through encrypted apps, per the Post, but law enforcement around the world could use the tactic to track down activists and others too.

It also sheds light on why Apple might have chosen to update its law enforcement guidelines late last year to require a court order to provide customers’ push notification data.

Proton Pass is now available as a Windows app.

Proton’s end-to-encrypted password manager launched last year — but only on the web, Android, and iOS. This new Windows app lets you access your passwords offline (as long as you have a Proton Pass Plus or Unlimited subscription). It also keeps passwords protected with the Argon2 hashing algorithm.

Proton is planning to launch its password manager on macOS and Linux later this year.

LockBit is back to attacking.

US and UK law enforcement disrupted LockBit last week, allowing them to seize the ransomware group’s websites and servers. Despite this effort, LockBit came back online with a new site for data leaks just days later.

But now, Bleeping Computer reports the group is carrying out new attacks with “updated encryptors with ransom notes linking to new servers.” The new servers are only accessible to the victims of LockBit’s latest attacks, Bleeping Computer reports.

Passkeys on X are now available to all US users on iOS.

The platform started rolling out passkey support on its iOS app last month, but now it’s available to all iPhone users in the US. That means you can use Face ID, Touch ID, or your device’s passcode to log in to your account instead of entering a password. You can learn how to enable passkeys on X from this support page.

Is LockBit back in control?

It’s been four days since the FBI announced it had disrupted the group, and now, cybersecurity researcher Kevin Beaumont reports that LockBit seems to have surfaced with claims that it has struck back at the US intelligence agency. Malware tracker vx-underground says the group now has new TOR domains.

The US State Deparment has offered a $15 million reward for information that results in arrests of LockBit attackers.

Julius “Zeekill” Kivimäki, Lizard Squad hacker, is arrested (again).

Cybersecurity blogger Brian Krebs reshared this post showing Kivimäki has been arrested in Helsinki after disappearing when a Finnish appeals court overturned his release from prison.

Kivimäki was initially arrested in France last year for allegedly hacking the Vastaamo online therapy center and leaking patient info online.

Microsoft says its automated AI red teaming tool finds malicious content “in a matter of hours.”

PyRIT, or Python Risk Identification Toolkit, can point human evaluators to “hot spot” categories in AI that might generate harmful prompt results.

Microsoft used PyRIT while redteaming (the process of intentionally trying to get AI systems to go against safety protocols) its Copilot services to write thousands of malicious prompts and score the response based on potential harm in categories that security teams can now focus on.

AT&T says its massive wireless outage was probably not due to a cyberattack.

After AT&T wireless service went out for many customers and even first responders across the US Thursday morning, one of the concerns was that the problem, and AT&T’s long delay before making a public statement about it, indicated a possible security breach.

However, according to this tweet, the company thinks it has identified the cause, described as “ the application & execution of an incorrect process used as we were expanding our network.”

The journalist who leaked Kanye West’s unaired Fox News rant has been arrested.

Tim Burke faces 14 federal charges in connection to an alleged hack on Fox News, which leaked unreleased portions of a Tucker Carlson interview where West went on an antisemitic rant. The indictment claims Burke and a co-conspirator used “compromised credentials” to “access and save protected commercial broadcast video streams,” according to the Tampa Bay Times.

Following an FBI raid on Burke’s home last year, his lawyers argued he accessed the video feed with no username or password required. “It’s not hacking, it’s just good investigative journalism,” Michael Maddux, Burke’s lawyer, told the Tampa Bay Times on Thursday.

Federal agencies are investigating whether this morning’s AT&T outage was a cyberattack.

ABC News reports the FBI and Department of Homeland Security (DHS), and other federal agencies, are “urgently investigating” the nation-wide outage to determine if it really was a cyberattack, or a not-so-nefarious technical mishap.

Reuters also has notes from White House spokesperson John Kirby’s comments to reporters:

When asked if government communication was disrupted by AT&T outages, Kirby said: “There was some impact to Commerce (Department) but I don’t know the extent of that, I don’t think it was crippling.” He added that the FirstNet nationwide public safety network was hit but had been fully restored.

U.S. officials have been told that AT&T had no reason to think this was a cybersecurity incident, Kirby said.
