As the title of this blog states, this short blog is about malware reverse engineering. This seems to be a very popular topic among security experts. The idea of reverse engineering of malware is to find out what weakness did the malware expose on your side (network, operating system, etc).
After researching for approximately 3 days, this is one tough area to learn. Assembly language and system calls are the two objectives that you are looking into when dissembling malware. The system I used is Late 2013 iMac with a Windows 7 virtual machine installed on it. The virtual machine is isolated and is not connected to the network. I did use a dissembler which was used for static analysis. Debugger is great because it provides you with a great sense of on the fly action that the malware migh execute. Debuggers that I consider valuable are: IDA Pro, Immunity Debugger and Oly Debugger. The one I spent most time on was IDA Pro. Keep in mind that these tools are not cheap. IDA Pro for example Starter edition is USD$589 and Pro is US$1129. I do believe this particular area will see significant growth as Malware becomes more sophisticated and the attacks turn toward mobile users.
What was I able to do in 3 days? Take a look at the diagram above. I did manage to dissemble one particular type of Malware, however my skills are fairly basic in this area, and I’m unsure if I got all the systems calls. This was a Windows based Malware, see if you can guess what Malware it is?
WannaCry Ransomware received how many payments?
The three bitcoin wallets tied to #WannaCry ransomware have received 296 payments totaling 48.86359565 BTC ($99,448.11 USD).

On February 18, 2017 Tavis Ormandy, a research analyst with Google’s Project Zero, revealed delicate information spilling from sites utilizing Cloudflare’s proxy services, which are utilized for their content delivery network (CDN) and distributed denial-of-service (DDoS) mitigation services. Cloudflare gives an assortment of services to a ton of sites – to at least couple of million. Tavis informed Cloudflare promptly. A couple includes in Cloudflare’s intermediary services had been utilizing an imperfect HTML parser that spilled uninitialized memory from Cloudflare’s edge servers in some of their HTTP reactions. Helpless components in Cloudflare’s services were handicapped inside hours of accepting Tavis’ divulgence, and their services were completely fixed with every defenseless element completely re-empowered inside three days. Cloudflare has a point by point review about Cloudbleed’s basic issue and their reaction to it – Click here.
Not if you are hosted with Primary Technologies. We have NEVER endorsed third party CDN providers such as Cloudflare. If you are or been hosted elsewhere than your data may have been spilled. Any merchant’s site utilizing Cloudflare’s intermediary service could have uncovered your passwords, session treats, keys, tokens, and other touchy information. In the event that your association utilized this Cloudflare intermediary benefit between September 22, 2016 and February 18, 2017, your information and your clients’ information could have been spilled and stored via web crawlers.
Prior to Tavis’ divulgence, information had been spilling for quite a long time. It’s too early to know the full extent of the information that was spilled and the locales and services that were influenced (in spite of the fact that we’re headed toward a nice begin). There is right now a decent lot of perplexity and misalignment on the status of different services.
Therefore, if you are looking to jailbreak manually, CLICK HERE. Instructions are detailed and if you follow them, you should be able to jailbreak your device.
As mentioned in our previous post, if you have updated to the latest iOS 10.2, this kernel exploit will not work. Please downgrade to 10.1.1 (still signed by Apple).
According to multiple sources iOS 10.2 has closed all the kernel vulnerabilities that were available. If you have any hope to jailbreak your iDevice on iOS10, simply upgrade to the last version that appears to be jailbreakable which is 10.1.1. As of right now its still signed and its possible to downgrade if you made a mistake and jumped on 10.2.
iCloud bypass … is it?
1. When you are asked to join a network, simply choose a new network and in the first field simply put many emojis into it. If you get around 100 in there, simply copy and paste until you feel that the phone has locked up.
3. Then start swiping all over the screen. Anywhere. Go crazy.
4. That’s it, the password screen should crash and it should take you to the springboard. Problem is, when you get there you can’t do anything.
Is it really a iCloud bypass? Well, you are getting by one screen, but you are still locked out. I personally thought it was the real deal, but its not.

This strange pop-up started occurring via Safari. Every time Safari was opened it would simply open the mail up and it kept re-opening every time you canceled. I couldn’t figure out which website was the offender. Regardless if you see phone number: 1-844-423-2465 (not affiliated with Apple) it is a good indication that your Safari has somewhat been hi-jacked.
Solution: Simple go to Settings > Safari > Clear History and Website Data. That will hopefully solve your issue.
All others = hold down home button and power button.
Edit: I found an old iPod touch running iOS 8.4. And the video above had no issues locking it up. I wonder how far does this go?
Edit (December 3, 2016): The above has been patched on iOS 10.2b. It appeared to be a memory leak.
