Android Wallpaper Crashing Bug You Should Experience Android Wallpaper Crashing Bug At Least Once In Your Lifetime And Here’s Why
So aboriginal off, bethink the Unc0ver vulnerability/jailbreak from aftermost week? In the 13.5.1 iOS release, the basal blemish was fixed, closing the jailbreak. If you intend to jailbreak your iOS device, accomplish abiding not to install this update. That said, the accustomed admonishing applies: Be actual accurate about active age-old software.
An accomplishment in Apple’s web affidavit agreement was anchored in the accomplished anniversary . Assurance In With Apple is agnate to OAuth, and allows application an Apple annual to assurance in to added sites and services. Beneath the hood, a JSON Web Token (JWT) gets generated and anesthetized around, in adjustment to affirm the user’s identity. In theory, this arrangement alike allows affidavit afterwards advice the user’s email address.
So what could go wrong? Apparently a simple appeal for a JWT that’s active with Apple’s attainable key will automatically be approved. Yeah, it was that bad. Any annual affiliated to an Apple ID could be trivially compromised. It was anchored this accomplished week, afterwards actuality begin and appear by [Bhavuk Jain].
So aback addition posts an angel on twitter, and warns anybody to *never* use it as your buzz wallpaper, what’s the analytic affair to do? Apparently it’s alone adapted to anon set it as your phone’s wallpaper, and again accuse that it renders your buzz unusable. So what’s activity on?
The angel in catechism uses a appropriate color-space that the Android UI isn’t able to handle. That accurate account has a blush amount over 255, which is out of bounds, causing a blast in the UI. Once the Android UI has crashed, it’s absurd to change the wallpaper, arch to a blast loop. A few users were able to about-face out their wallpapers in the few moments amid crashes, but the surest way to apple-pie up the blend is to manually abolish the angel application article like TWRP.
This vulnerability is one that keeps on giving. We talked about CVE-2019-10149 aloof about a year ago. This week, the NSA appear a admonishing (PDF) that assertive accompaniment actors are actively base this Exim bug.
For a quick refresher, the Exim mail server is the best accepted mail server on the net. CVE-2019-10149 is a able accomplishment that tricks a attainable server into aggravating to accelerate an email to a distinctively crafted address, hosted at a awful mail server. Aback the ambition apparatus tries to accelerate a bounceback message, the awful server sends a byte every four minutes, banishment the affiliation to break attainable for a week. This activity ensures that the attainable cipher is hit. Aback the bulletin is assuredly sent, the burden anchored in the email abode is evaluated and executed.
The NSA admonishing specifies the Russian GRU as the culprit, acting beneath the name Sandworm. There’s acceptable absolutely the adventure abaft how the accepted attacks were apparent to be of Russian origin. As none of the indicators of accommodation are anon angry to the GRU, we’ll aloof accept to booty the NSA’s chat for it, but of advance they’re not activity to accomplish attainable how they get their counter-intel either.
In added GRU news, the UK has clearly attributed to them a alternation of attacks on the country of Georgia. These attacks shut bottomward the Georgian ability grid, encrypted adamantine drives (ransomware), and anon damaged banking systems. And aloof aftermost month, the German government attributed hacks on their assembly to one accurate GRU officer: Dmitriy Badin.
Attributing cyber attacks to a accurate amateur is consistently tricky, abnormally aback adeptness adopted intelligence agencies which don’t appetite to get bent are abaft the work, but the actuality that assorted government agencies are advancing on the aforementioned abstracts is added persuasive. The German evidence, calm over bristles years and pointing to a accurate agent, is decidedly so.
Our final adventure comes from Sky News, who break the account that Westech International was hit with a ransomware attack. As you may accept guessed, this section’s appellation is Betteridge’s Law in action, admitting ironically.
So what absolutely happened, and why is the “nuclear secrets” bend about absolutely bunk? Aboriginal off, Westech isn’t a huge engineering firm, and they haven’t formed on designing any nuclear weapons systems. Go to their website, and attending at the affairs they accept and casework they offer. Telecommunications, maintenance, and acumen planning.
Secondly, we apperceive that the ransomware advance hit the machines accomplishing their payroll. Classified advice is accountable to a austere set of rules in the US. It’s alone to be kept and acclimated in a Sensitive Compartmented Advice Facility (SCIF). Computers absolute classified advice are never to be affiliated to the unsecure network. There is alike a committed Secret Internet Agreement Router Arrangement (SIPRNet) that is alone for defended communications and alone attainable from a SCIF. All this to say, if a ransomware advance can ex-filtrate abstracts aback to an attacker, again somebody royally messed up in a way that generally leads to bastille time. It’s a continued way from amount to nuclear secrets.
[Andrew Dupuis] had an Arris Cilia Aperture provided by AT&T, and like abounding a hacker, he wasn’t satisfied. Before we dive all the way into the rabbit-hole, we should point out that AT&T is charging $10 a ages for this device, and refuses to let their barter use their own accouterments instead. [Andrew] believes that this apparently violates FCC rules. In any case, he capital to run his own aperture instead of actuality bound into AT&T’s. The cilia affiliation uses 802.1x aegis on the concrete connection, which additionally serves to lock barter into the official hardware. If a user could abstract the 802.1x certificates, they could alter the official AT&T aperture with their own hardware, which is the point of the writeup.
The accomplishment itself starts with a firmware downgrade, aback to a adaptation that still contains the vulnerability. The vulnerability? A REST server advised for troubleshooting and debugging. A bit of assignment later, and the accouterments is rooted, with a telnet server aloof cat-and-mouse for you. It shouldn’t be actual surprising, the OS beneath the awning is a accepted anchored Linux. The aboriginal adjustment of business is to attenuate the auto-update function, to abstain accepting bound aback out of the device.
[Andrew] explains how to appropriately defended the gateway, and re-tune it for bigger performance, acceptable account if you intend to abide application it in your network. The absolute ambition actuality is extracting the certificates. I’m not abiding how abundant of a abruptness it should be, but it seems that every accessory uses the aforementioned aegis certificates, and [Andrew] was affectionate abundant to allotment the archetype he extracted.
[Andrew] beatific this in on the Hackaday Tipline. If you accept analysis to share, or came beyond article you anticipate we should cover, be abiding to let us apperceive about it!
