Mega Chrome Extension Hacked, Laced with Data-Stealing Malware

Mega Chrome Extension Hacked, Laced with Data-Stealing Malware

Mega Chrome Extension Hacked, Laced with Data-Stealing Malware. The official Chrome extension for the cloud storage and file sharing service –, has been compromised with malicious codes that steal user data for websites as well as private keys for cryptocurrency accounts.

The malicious variant was detected by security researchers in the source code of the Chrome extension version 3.39.4, released early Tuesday (04Sep2018) as an update and this has triggered a major security alert from the company. In response, MEGA announced the serious breach has affected an unknown number of users.

On the 4th September 2018 at 14:30 UTC, an unknown attackеr uploaded a trojaned version of MEGA’s Chrome extension, version 3.39.4, to the Google Chrome webstore,

it stated in a statement.

The New Zealand company says that whenever a user installs or auto-updates to the trojanеd extension, it seeks for permissions unlike the official extension. And this includes the ability to read and change ALL data on sites that the user visits. Experienced users may quickly suspect malicious activities but a vast majority of people would not have understood the risks.

Plеase note that if you visitеd any site or madе use of another extеnsion that sends plain-text crеdentials through POST rеquests, either by dirеct form submission or through a background XMLHttpRеquest (XHR) process while the trojanеd extension was active, considеr that your crеdentials were compromised on thеse websites and/or applications,

the company warns.

MEGA states that Google engineers have already removed the extension from the Chrome Web Store, and also disabled the variant extension for existing users.

Four hours aftеr the breach occurred, the trojanеd extension was updatеd by MEGA with a clеan version (3.39.5), auto-updating affеcted installations. Google rеmoved the extеnsion from the Chrome wеbstore five hours after the brеach,

the company explained.

According to an analysis about detecting the source of the trojaned extension, it was found that the malicious extension was programed to steal user credentials on specific websites like Amazon, Live (Microsoft), Google (Webstore), GitHub, MyMonero and MyEtherWallet web wallet services, as well as IDEX crypto trading platform.

While user data for these websites were specifically targeted, MEGA states that this is something serious due to the trojaned extension attempting to steal information. It would record usernames, passwords and other online session credentials that hackers would need to impersonate users. If it’s a cryptocurrency website, the hacker would be able to extract the private keys required to access users’ funds. The extension was also found to be sending all collected data to a server hosted in Ukraine and located at

This serious attack affects mainly those who had the auto-update MEGA Chrome extension enabled and had it installed at the time of the incident, or anyone who freshly installed v3.39.4 of the extension (and accepted permissions).

The attack was first discovered by a security researcher called SerHack, who immediately tweeted a warning that the v3.39.4 had been breached before other security experts quickly jumped in, analyzed the extension and reported their findings.

UK Fines Facebook over Cambridge Analytica Scandal


UK Fines Facebook over Cambridge Analytica Scandal. The UK has hit Facebook a fine of $645,000 for the Cambridge Analytica Scandal. It was revealed earlier this year that they had harvested the personal data of millions of profiles without the user’s consent and used it for political purposes. It is estimated that 87 million users were affected.


The fine has been enforced by the UK’s Information Commissioner’s Office (ICO) and was calculated using a pre-GDPR formula for data breach fines. Using the UK’s old Data Protection Act to fine Facebook, rather than GDPR they can only give a maximum penalty of £500,000, which is equal to what the social media giant earns every 18 minutes.


GDPR rules dictate a maximum fine of 4% of annual global turnover, which would be $1.6 billion. Unfortunately the the GDPR regulation wasn’t in place when the Cambridge Analytica story broke, coming into force in May 2018.


The UK investigation concluded that Facebook’s APIs had been allowing developers access to users information without them providing proper consent, for a long period of time between 2007 and 2014. Once they realized this loophole existed and patched it up, they did nothing to investigate the data compromised or ensure it was deleted.


[FACEBOOK] should have known better and it should have done better… We considered these contraventions to be so serious we imposed the maximum penalty under the previous legislation. The fine would inevitably have been significantly higher under the GDPR

Information Commissioner Elizabeth Denham said in a statement


Facebook has said they are reviewing the ICO’s findings and stated they “respectfully disagree” with some of the report, but admit they should have done more to protect users data. They also added that they found no evidence that British users profile information was shared with Cambridge Analytica.

Libssh Security Flaw leaves thousands of servers vulnerable to hijacking

Libssh Security Flaw leaves thousands of servers vulnerable to hijacking

Libssh Security Flaw leaves thousands of servers vulnerable to hijacking. A security flaw in libssh leaves thousands, and potentially more, servers vulnerable to an attack. Libssh is a multiplatform C library which allows users to remotely execute programs, transfer files, manage public keys and use a secure and transparent tunnel.


The security flaw, discovered by Peter Winter-Smith from NCC Group, allows a hacker to bypass the authentication process on the servers and gain access to the system without having to enter a password.


An attacker can do this by sending the SSH server “SSH2_MSG_USERAUTH_SUCCESS” message instead of the “SSH2_MSG_USERAUTH_REQUEST” message that a server usually expects and which libssh uses as a sign that an authentication procedure needs to initiate.


The libssh system will treat this message to mean the authentication has already taken place and allow the attacker access to the server. The flaw (CVE-2018-10933) was released in January 2014 in release 0.6.0.


It’s estimated that the vulnerability currently affects at least 3000 servers, however this is based on a small search and the scale of the problem is not yet known. There were concerns that the popular version control site for developers to work collaboratively on projects, GitHub, was affected but they have released a statement denying this. Github claims the way they use libssh means they are not vulnerable to this exploit.


“We use a custom version of libssh; SSH2_MSG_USERAUTH_SUCCESS with the libssh server is not relied upon for pubkey-based auth, which is what we use the library for,”

a GitHub security official said on twitter


The security flaw is only on the server side, meaning users who have a libssh based SSH client installed on their computer will be safe from potential attackers looking to exploit this vulnerability.


While there are currently no public exploits available for the vulnerability, they are easy to put together so these are likely to pop up online in the coming days and weeks.

The team at libssh released versions 0.8.4 and 0.7.6 yesterday to handle this bug.

Ad Clicker Disguised as a Google Photos App has been Hosted on Microsoft Store.

Ad Clicker Disguised as a Google Photos App has been Hosted on Microsoft Store

Ad Clicker Disguised as a Google Photos App has been Hosted on Microsoft Store.


A malicious app called “Album by Google Photos” was found to be hosted on the Microsoft store. The app was pretending to be part of Google Photos, but was in fact an ad clicker that generates hidden adverts within the Windows 10 Operating System.


The ad clicker app seemed credible to users because of its name, and also the fact it claimed to be created by Google LLC, Google’s actual Microsoft store account is Google Inc, but it looks unsuspecting to users. Microsoft came under some criticism for not realising the app was actually malicious software since the user reviews did highlight that the app was fake, with plenty of 1* reviews. One review states “ My paid Anti-malware solution detected several attempts to download malware by this app. Watch out”. The App was first released on the Microsoft store in May.


What did the application do?


The “Album by Google Photos” app is a Progressive Web Application (PWA), which acts as the front end for Google Photos and includes a legitimate login screen. Hidden in the app bundle is also an ad clicker which runs in the background and generates income for the app developers.


The app connects to ad URLS, and the ads were very similar to what users would see from typical adware, including tech support scams, random chrome extensions, fake flash and java installs and general low-quality sites.


Microsoft haven’t commented how this app managed to pass the Microsoft review process before ending up on the store.  This is somewhat concerning since it could mean other malicious apps of a similar nature have flown under the radar and are still infecting user’s computers. We are waiting for Microsoft to comment on the issue.
