Researcher Releases ‘Permanent Unpatchable Bootrom’ iOS Exploit Checkm8 That Could Cause Serious Problems for iPhone, iPad Hardware

An iOS security researcher who goes by axi0mX on Twitter and Github posted a new software tool called Checkm8 that he claims uses a “permanent unpatchable bootrom exploit” that could bypass boot security for millions of Apple devices, from the iPhone 4S to the iPhone X. The researchers did not release a full jailbreak, but an exploit that can be used it to dump SecureROM [the boot ROM code], decrypt keybags [the escrow memory with the keys for all encrypted data on the device] with AES engine, and demote the device to enable JTAG. It’s possible other researchers have found the exploit and are already using it, especially via tools used by intelligence and law enforcement agencies, such as GreyShift’s GreyKey.

@axi0mX: EPIC JAILBREAK: Introducing checkm8 (read "checkmate"), a permanent unpatchable bootrom exploit for hundreds of millions of iOS devices.Most generations of iPhones and iPads are vulnerable: from iPhone 4S (A5 chip) to iPhone 8 and iPhone X (A11 chip).
@lilyhaynewman: today a researcher dropped a really rare type of exploit that can be used to jailbreak EIGHT generations of iPhones *and* the vuln is unfixable. so that's a thing now.
@andreabarisani: What was I saying recently about unpatchable bootrom exploits?We find them constantly in automotive grade SoCs. Consumer products have even larger attack surface...Future hacks will more and more target the code embedded in the silicon.
@campuscodi: NEW: New Checkm8 jailbreak released for all iOS devices running A5 to A11 chips-works on iPhones 4S up to iPhone 8 and X -doesn't support A12 and A13 chipsets -code available on GitHub -uses "a permanent unpatchable Bootrom exploit"https://zdnet.com/article/new-checkm8-jailbreak-released-for-all-ios-devices-running-a5-to-a11-chips/
@thomasreed: If you haven’t heard yet, an exploit was dropped on Twitter this morning capable of modifying the bootrom on nearly all iOS devices except the most recent. Learn about the possible implications here:
@dangoodin001: Good writeup for anyone trying to understand the security consequences of the Checkm8 exploit.

Attackers Exploited Stealthy Zero-Day Flaw in iTunes and iCloud to Infect Windows Computers with BitPaymer Ransomware

Attackers exploited a zero-day vulnerability in Apple’s iTunes and iCloud programs to infect Windows computers with ransomware without triggering antivirus protections, researchers from Morphisec reported. The bug, known as an unquoted service path, is in the Bonjour component on which both iTunes and iCloud for Windows rely. When it’s in a trusted program such as one digitally signed by a well-known developer like Apple, attackers can exploit the flaw to make the program execute code that AV protection might otherwise flag as suspicious. Morphisec discovered in August that the attackers were exploiting the vulnerability to install ransomware called BitPaymer on the computers of an unidentified company in the automotive industry and reported it to Apple. Apple patched the vulnerability in both iTunes 12.10.1 for Windows and iCloud for Windows 7.14. The iTunes uninstaller doesn’t automatically remove Bonjour, so anyone who has ever installed and later uninstalled iTunes should inspect their PCs to ensure Bonjour is not present.

Equifax Settlement Administrator Says Breach Victims Seeking Cash Must Jump Through Additional Hoop and Provide More Information

The Equifax settlement administrator is forcing the millions of Americans who requested cash compensation from the settlement reached between the Federal Trade Commission and Equifax as a result of the credit rating agency’s massive data breach to now jump through another hoop by certifying before October 16 that they already have some form of credit monitoring services in place. Because the $31 million reserved for paying cash compensation was dwarfed by the sheer number of claimants, the FTC is hoping to winnow down the number of cash claimants through this additional step. Those who requested compensation can alternatively apply for free credit monitoring, a choice that the administrator indicates is likely the better option.

Controversial Cryptography Company Crown Sterling Touts Decryption Accomplishment, Experts Immediately Deride Company’s Claim

Controversial digital cryptography company Crown Sterling issued a press release claiming that it had decrypted two RSA 256-bit asymmetric public keys in approximately 50 seconds from a standard laptop computer before a gathering of what the press release says is “approximately 100 academics and business professionals,” a claim met with great derision among experts who understand cryptography. Crown Sterling also released a video of the decryption demonstration. Crown Sterling has been promoting its “Time AI” cryptographic system which it says will fix the breakable-ness of RSA cryptography by using an entirely different method of generating keys, one that doesn’t rely on factoring large prime numbers. The company is suing cybersecurity conference Black Hat for alleged breach of contract over a sponsored presentation it gave at the event in August, which generated jeers from the presentation attendees.

@TheSweetKat: Breaking news: Crown Sterling cracks symmetric encryption method known as ROT-13
@gregotto: Crown Sterling (the company that is suing Black Hat) just sent out a press release saying it decrypted RSA keys Thursday in front of a room full of academics in California yesterday.If you were in that room, I would like to speak with you
@LargeCardinal: I think @matthew_d_green has done stuff on this, but these numbers don't seem that impressive... Doing some digging now.
@henrykploetz: Well, this is Sagemath on my Ultrabook (X1 Carbon 2017). I'm assuming the default implementation is single-threaded. So, "50 seconds" is exactly the expected performance on a 4-core laptop.
@erratarob: Cracking 256-bit RSA keys is simple and not a convincing demonstration. Whatever you demo in a controlled setting with a laptop is not believable, since you can cheat. This means nothing.Solving any real-world problem, such as the above key, is what would convince people.
@malwaretechblog: Who exactly are they trying to impress? You can factor 256 bit RSA on a smartphones in < 1h, and 512 bit is doable in a few mins with a EC2 cluster.
@matthew_d_green: These Crown Sterling people are going to launch a cryptocurrency, mark my words.

Glut of Working iOS Exploit Chains Prompts Zerodium to Pay Higher Price for Android Zero-Days for the First Time Ever

For the first time ever, the security exploit broker Zerodium is paying more for zero-day attacks that target Android than it pays for comparable attacks targeting iOS according to the company’s updated price list. Zerodium will now pay $2.5 million for each “full chain (Zero-Click) with persistence” Android zero-days compared with $2 million for iOS zero-days that meet the same criteria. The previous price for an iOS exploit was $2 million but Zerodium made no mention of Android. According to Zerodium founder and CEO Chaouki Bekrar, a glut of working iOS exploit chains has coincided with the growing difficulty of finding comparable exploits for versions 8 and 9 of Android.

Would-Be Digital Cryptography Firm Crown Sterling Sues Black Hat Conference Organizers, Ten ‘Doe’ Defendants Over Disruption at Sponsored Presentation

After almost getting booed off the stage at Black Hat, “emerging digital cryptography” firm Crown Sterling is suing conference company UBM alleging that its Black Hat USA event had breached “its sponsorship agreement with Crown Sterling and the implied covenant of good faith and fair dealing arising therefrom.” The company also accuses the conference organizers of “other wrongful conduct” connected to events surrounding the presentation of a paper by Crown Sterling CEO and founder Robert E. Grant. In addition to legally targeting the conference, Crown Sterling has also filed suit against 10 “Doe” defendants, who it claims orchestrated disruption of the company’s sponsored talk at Black Hat. Before, during and after the conference, cryptographers were extremely skeptical with what Crown Sterling was pitching, with some referring to the talk as “snake oil crypto.”

@malwarejake: Does Crown Sterling know there are photos and videos of the room? Because you can call this room a lot of things, but "filled to capacity with conference attendees" isn't one of them...
@gossithedog: Remember the TIME AI(tm) people, Crown Sterling, who bought a talk at Black Hat and then presented laughable rubbish buzzword nonsense? They’re suing Black Hat. If this was a smaller con it would finish them. Never give Crown Sterling a stage again, any and every event.

App With 100 Million Downloads on Google Play Store, CamScanner, Included Malicious Trojan Dropper That Executed Secret Payloads

An app, CamScanner, with 100 million downloads contained a malicious component that downloaded secret payloads onto infected Android devices, according to researchers at Kaspersky. Although a legitimate app that provided useful functions for scanning and managing documents for most of its life, CamScanner changed at some point to include an advertising library that contained a malicious module known as a “Trojan dropper,” which executed code from a designated server and then decrypted and executed it on an infected device. Kaspersky calls the module Trojan-Dropper.AndroidOS.Necro.n.

Card-Skimming Malware Operators Magecart 5 Appear to Be Targeting Level 7 Routers Associated With Wi-Fi Networks Used at Airports, Hotels, Resorts and Some Retail Environments

A known group of criminal Web malware operators called Magecart 5 appears to be targeting commercial layer 7 routers typically associated with Wi-Fi networks commonly used to provide free or paid Wi-Fi Internet access at airports, hotels, resorts, and even in some retail environments, researchers at IBM X-Force IRIS report. Magecart 5 is one of many groups associated initially with the Magecart card skimming malware. The IBM researchers also found that the group is corrupting an open-source mobile application library used to create touch “sliders” to allow users to swipe through galleries “to ensure that every developer using the slider will end up serving the attackers’ malicious code, leading to the compromise of user data of those using the finished product.”

Threat Group Tortoiseshell Is Targeting U.S. Military Veterans and Companies With Malicious Employment Site, Installs Spyware to Collect Data About Target Systems

A threat group, Tortoiseshell, previously identified as being behind a set of attacks on IT providers in Saudi Arabia, has now been spotted targeting US military veterans and companies with a malicious webpage, hiremilitaryheroes.com, that purports to be an employment site, according to Cisco Talos. The bogus site offers a free desktop client which is, in reality, a spyware installer. Tortoiseshell is reported to be behind attacks on eleven companies in Saudi Arabia. All of the attacks used the same remote access tool, Backdoor.Syskit by Symantec, coded in both Delphi (the Object Pascal programming language introduced by Borland) and Microsoft .NET. A similar backdoor, named “IvizTech” in this case, is part of a package dropped by the website discovered by Talos. When the installer connects, it downloads two files from a server hosted by a company in Atlanta: a reconnaissance tool and the backdoor. If it fails to install, the backdoor sends an email to a Gmail address from another Gmail address (ericaclayton2020@gmail.com), the credentials for which are hard-coded in the installer. The reconnaissance tool, with the filename “bird.exe,” is internally named Liderc, collects data about the infected system, including date, time, installed drivers, patch level, network configuration, domain controller, name of the administrator account, and a list of other accounts available.

Flagstaff Cancels Classes in Its School District Due to Ransomware Discovered During Routine Maintenance

All classes were canceled September 5 at Flagstaff Unified School District (FUSD) schools in Arizona after the discovery of a ransomware attack against the district’s servers during routine maintenance on Wednesday, September 4. The district says all FUSD issued devices, including laptops, at all sites need to be updated and asked all FUSD employees to bring any Windows-based laptops to Sinagua Middle School by 9 a.m. Friday. Officials say they have to “break the connection” from the Internet to all school devices to mitigate the issue.
