Fujifilm Fights Ransomware Attack and Works to Restore Servers

Andrew Orr ·

Fujifilm was hit by a ransomware attack last week but refuses to pay the ransom. Instead, it’s working to restore its servers with backups.

On 4 June it confirmed a ransomware attack was affecting a “specific network” in Japan and that it shut down “all networks and server systems” while it investigated the “extent and scale” of the attack.

Fujifilm said it would not comment on the amount demanded by the ransomware gang. The company has started bringing its network, servers, and computers in Japan “back into operation” and is aiming to be fully up and running “this week”. It has also restarted some product deliveries, which were particularly hard hit by the cyberattack.

'RockYou2021' is the Biggest Password Leak Ever (So Far)

Andrew Orr ·

Someone posted a 100GB text file to a hacking forum recently. It contains 8.4 billion entries of passwords from data leaks and breaches.

Considering the fact that only about 4.7 billion people are online, numbers-wise the RockYou2021 compilation potentially includes the passwords of the entire global online population almost two times over. For that reason, users are recommended to immediately check if their passwords were included in the leak.

“Two times over” sounds like it’s a combination of old and new passwords alike. It’s also good to point out that no usernames or email addresses were included, so an attacker wouldn’t be able to do much with this password list.

$2.3 Million Bitcoin Seized from Colonial Pipeline Hackers

Andrew Orr ·

The U.S. Department of Justice seized about US$2.3 million in bitcoin ransom paid to the hackers behind the attack on Colonial Pipeline.

An affidavit filed on Monday said the FBI was in possession of a private key to unlock a bitcoin wallet that had received most of the funds. It was unclear how the FBI gained access to the key.

“unclear how the FBI gained access.” From other sources it sounds like the FBI used a subpoena and gained control over the rented cloud server the hackers were using. Private key sitting on the server, it seems.

How to Get Around macOS Security Using App Installers

Andrew Orr ·

Tenable Research found security issues related to macOS app installers, and they can be used to bypass default Mac security protections. So far, Apple hasn’t fixed it (emphasis mine).

Frustrated by the prevalence of these issues, we decided to write them up and make separate reports to both Apple and Microsoft. We wrote to Apple to recommend implementing a fix similar to what they did for CVE-2020–9817 and explained the additional LPE mechanism discovered.

We wrote to Microsoft to recommend a fix for the flaw in their installer. Both companies have rejected these submissions and suggestions.

Postal Workers Targeted With Phishing Campaign

Andrew Orr ·

Postal workers returning to the office after COVID-19 restrictions may find themselves targeted by a new phishing campaign.

The email-based campaign, observed by Cofense, is targeting employees with emails purporting to come from their CIO welcoming them back into offices.

The email looks legitimate enough, sporting the company’s official logo in the header, as well as being signed spoofing the CIO. The bulk of the message outlines the new precautions and changes to business operations the company is taking relative to the pandemic.

It is another example of how important public/private partnerships are in the fight against cybercrime.”

WebKit Flaw Crashes Safari, Could Lead to Further Exploits

Andrew Orr ·

A WebKit flaw on iOS and macOS can cause Safari to crash and could lead to further malicious attacks.

The vulnerability stems from what security researchers call a type confusion bug in the WebKit implementation of AudioWorklet, an interface that allows developers to control, manipulate, render, and output audio and decrease latency. Exploiting the vulnerability gives an attacker the basic building blocks to remotely execute malicious code on affected devices.

Researcher Fabian Bräunlein found that Apple’s Find My location network can be used to “upload arbitrary data to the internet.”
