‘WannaCry’ ransomware attack spreads worldwide (update)

England’s healthcare system came under a withering cyberattack Friday morning, with ” at least 25 ” hospitals across the country falling prey to ransomware that locked doctors and employees out of critical systems and networks. The UK government now reports that this is not a (relatively) isolated attack but rather a single front in a massive regionwide digital assault. #nhscyberattack pic.twitter.com/SovgQejl3X — gigi.h (@fendifille) May 12, 2017 The attack has impacted hospitals and transportation infrastructure across Europe, Russia and Asia. Organizations in dozens of countries have all been hit with the same ransomware program, a variant of the WannaCry virus, spouting the same ransom note and demanding $300 for the encryption key, with the demand escalating as time passes. The virus’s infection vector appears to through a known vulnerability, originally exploited and developed by the National Security Agency. That information was subsequently leaked by the hacking group known as Shadow Broker which has been dumping its cache of purloined NSA hacking tools onto the internet since last year. The virus appears to have originally spread via email as compressed file attachment so, like last week’s Google Docs issue, make sure you confirm that you email’s attachments are legit before clicking on them. Also, make sure your computers are using software that’s still receiving security updates, and that you’ve installed the latest updates available. Microsoft released a fix for the exploit used as a part of its March “Patch Tuesday” release, but unpatched Windows systems remain vulnerable. Update : Reuters reports a statement from Microsoft indicating that engineers have added detection and protection against the “Ransom:Win32.WannaCrypt” malware, so make sure your Windows Defender or other antivirus is updated before logging on to any corporate networks that may be infected. In a statement, a FedEx representative confirmed its systems are being impacted, saying “Like many other companies, FedEx is experiencing interference with some of our Windows-based systems caused by malware. We are implementing remediation steps as quickly as possible. We regret any inconvenience to our customers.” Source: New York Times

Microsoft Word 0-day used to push dangerous Dridex malware on millions

Enlarge / A sample e-mail from Dridex campaign exploiting Microsoft Word zero-day. (credit: Proofpoint) Booby-trapped documents exploiting a critical zero-day vulnerability in Microsoft Word have been sent to millions of people around the world in a blitz aimed at installing Dridex, currently one of the most dangerous bank fraud threats on the Internet. As Ars reported on Saturday, the vulnerability is notable because it bypasses exploit mitigations built into Windows, doesn’t require targets to enable macros, and works even against Windows 10, which is widely considered Microsoft’s most secure operating system ever. The flaw is known to affect most or all Windows versions of Word, but so far no one has ruled out that exploits might also be possible against Mac versions. Researchers from security firms McAfee and FireEye warned that the malicious Word documents are being attached to e-mails but didn’t reveal the scope or ultimate objective of the campaign. In a blog post published Monday night , researchers from Proofpoint filled in some of the missing details, saying the exploit documents were sent to millions of recipients across numerous organizations that were primarily located in Australia. Proofpoint researchers wrote: Read 2 remaining paragraphs | Comments

Malwarebytes Discovers ‘First Mac Malware of 2017’

wiredmikey writes: Security researchers have a uncovered a Mac OS based espionage malware they have named “Quimitchin.” The malware is what they consider to be “the first Mac malware of 2017, ” which appears to be a classic espionage tool. While it has some old code and appears to have existed undetected for some time, it works. It was discovered when an IT admin noticed unusual traffic coming from a particular Mac, and has been seen infecting Macs at biomedical facilities. From SecurityWeek.com: “Quimitchin comprises just two files: a .plist file that simply keeps the .client running at all times, and the .client file containing the payload. The latter is a ‘minified and obfuscated’ perl script that is more novel in design. It combines three components, Thomas Reed, director of Mac offerings at Malwarebytes and author of the blog post told SecurityWeek: ‘a Mac binary, another perl script and a Java class tacked on at the end in the __DATA__ section of the main perl script. The script extracts these, writes them to /tmp/ and executes them.’ Its primary purpose seems to be screen captures and webcam access, making it a classic espionage tool. Somewhat surprisingly the code uses antique system calls. ‘These are some truly ancient functions, as far as the tech world is concerned, dating back to pre-OS X days, ‘ he wrote in the blog post. ‘In addition, the binary also includes the open source libjpeg code, which was last updated in 1998.’ The script also contains Linux shell commands. Running the malware on a Linux machine, Malwarebytes ‘found that — with the exception of the Mach-O binary — everything ran just fine.’ It is possible that there is a specific Linux variant of the malware in existence — but the researchers have not been able to find one. It did find two Windows executable files, courtesy of VirusTotal, that communicated with the same CC server. One of them even used the same libjpeg library, which hasn’t been updated since 1998, as that used by Quimitchin.” Read more of this story at Slashdot.

A $300 Device Can Steal Mac FileVault2 Passwords

An anonymous reader writes: Swedish hardware hacker Ulf Frisk has created a device that can extract Mac FileVault2 (Apple’s disk encryption utility) passwords from a device’s memory before macOS boots and anti-DMA protections kick in. The extracted passwords are in cleartext, and they also double as the macOS logon passwords. The attack requires physical access, but it takes less than 30 seconds to carry out. A special device is needed, which runs custom software (available on GitHub), and uses hardware parts that cost around $300. Apple fixed the attack in macOS 10.12.2. The device is similar to what Samy Kamker created with Poison Tap. Read more of this story at Slashdot.

Researchers Create An Undetectable Rootkit That Targets Industrial Equipment

An anonymous reader quotes Bleeping Computer: “Two researchers presenting at the Black Hat Europe security conference in London revealed a method of infecting industrial equipment with an undetectable rootkit component that can wreak havoc and disrupt the normal operations of critical infrastructure all over the world. The attack targets PLCs (Programmable Logic Controllers), devices that sit between normal computers that run industrial monitoring software and the actual industrial equipment, such as motors, valves, sensors, breakers, alarms, and others.” Researchers say they packed their attack as a loadable kernel module [PDF], which makes it both undetectable and reboot persistent. The attack goes after PLC pin configurations, meaning the PLC won’t be able to tell which are the actual input and output pins, allowing the attacker full-control to make up bogus sensor data, send fake commands, or block legitimate ones. The researchers acknowledge that the attack is extremely complicated, but the article argues it would still be of interest to a state-sponsored actor. Read more of this story at Slashdot.

Using Rowhammer bitflips to root Android phones is now a thing

Enlarge / An LG Nexus 5 at the moment it is rooted using Rowhammer-induced bit flips. (credit: van der Veen et al.) Researchers have devised an attack that gains unfettered “root” access to a large number of Android phones by exploiting a relatively new type of bug that allows adversaries to manipulate data stored in memory chips. The breakthrough has the potential to make millions of Android phones vulnerable, at least until a security fix is available, to a new form of attack that seizes control of core parts of the operating system and neuters key security defenses. Equally important, it demonstrates that the new class of exploit dubbed Rowhammer can have malicious and far-reaching effects on a much wider base of devices than was previously known, including those running ARM chips. Previously, some experts believed Rowhammer attacks that altered specific pieces of security-sensitive data weren’t reliable enough to pose a viable threat because exploits depended on chance hardware faults or advanced memory-management features that could be easily adapted to repel the attacks. Now, an international team of academic researchers is challenging those assumptions by demonstrating a Rowhammer exploit that alters crucial bits of data in a way that completely roots name brand Android devices from LG, Motorola, Samsung, OnePlus, and possibly other manufacturers. An app containing the researchers’ rooting exploit requires no user permissions and doesn’t rely on any vulnerability in Android to work. Read 17 remaining paragraphs | Comments

“Most serious” Linux privilege-escalation bug ever is under active exploit (updated)

(credit: michael ) A serious vulnerability that has been present for nine years in virtually all versions of the Linux operating system is under active exploit, according to researchers who are advising users to install a patch as soon as possible. While CVE-2016-5195, as the bug is cataloged, amounts to a mere privilege-escalation vulnerability rather than a more serious code-execution vulnerability, there are several reasons many researchers are taking it extremely seriously. For one thing, it’s not hard to develop exploits that work reliably. For another, the flaw is located in a section of the Linux kernel that’s a part of virtually every distribution of the open-source OS released for almost a decade. What’s more, researchers have discovered attack code that indicates the vulnerability is being actively and maliciously exploited in the wild. “It’s probably the most serious Linux local privilege escalation ever,” Dan Rosenberg, a senior researcher at Azimuth Security, told Ars. “The nature of the vulnerability lends itself to extremely reliable exploitation. This vulnerability has been present for nine years, which is an extremely long period of time.” Read 6 remaining paragraphs | Comments
