Topic: Beware of Increasingly Sophisticated Malware Infection Attempts - page 22. (Read 835397 times)

This is terrible, I really thank you, because I almost caught, and now I start to install Adblock, I hope to block all the malwares from online websites.

somebody took my ether today from mew. how can that be possible?

Now a days a lot of phishing and malware infected hacking attempts are happening
due to bad guys who want to steel your personal information specially private keys.
Block chain technology is a good technology but still it has a lot of problems that
need to be addressed. I want in every cryptocurrency wallet there should be
double factor authentication key that work with Google authenticator.

I was thinking if there is way to automatic delete any Malware link post on this forum so that we may not even get to open the link.

In the past months, malware infection attempts on this forum has become increasingly sophisticated. Below is a summary of infection techniques that I have encountered. With the most sophisticated attacks, common sense and virus scans is no longer sufficient to ensure safety.

"latest wallet"/"custom wallet"/"faster miner"
A newbie asks for the latest wallet, or wallet that doesn't have any tx fees, or the latest/fastest miner, and the attacker posts his in response. This type of attempt Usually gets spotted pretty quickly.

Copied/new ANN
The attacker creates a new ANN topic and posts a malware link as the wallet (or a legit one and changes it to a malware one later).

Replacing links in quotes
The attacker quotes a legitimate post containing a download link written by the real developer (usually the OP or a update post) and changes the link within the quote to a malware link.

Compromised dev account
The developer account (usually responsible for making the OP) is compromised and a "mandatory update" is posted. This usually happens with old/abandoned coins so the real developer isn't there to notice the rogue update.

Packed/FUD executables
In most of the cases above, the malware has little to now detections on virustotal. This is because any script kiddie can pay $30 and have their malware crypted, rendering them fully undetectable.

Modified source with backdoor
This was recently brought to my attention via a user report. A newbie, under the guise of reviving a coin posted a new client along with source. However, the source was modified to include a backdoor in the IRC bootstrapping mechanism.
here is the relevant source code:
here is the source code with macros resolved:
The code was part of the initial commit, so it would be difficult to notice the addition of the code by casual inspection. Also, this would likely not show up on any virus scans.
