Michael "Veteran" Archer, former head coach for European League of Legends teams Schalke 04 Esports and H2K, has drawn attention to a series of Reddit threads that claim the BlitzGG app is part of a widespread issue that is attempting to install malware on users' systems.
Initially thought to be a background Bitcoin mining operation related specifically to BlitzGG, it now seems to be a more widespread malware attack that aims to trick people into updating Electrum, a popular Bitcoin wallet.
A popup has appeared through the BlitzGG app, asking users to update Electrum to avoid a 'vulnerability'.
According to users in this Reddit thread, the issue affects multiple websites, browsers and operating systems, from Chrome and Safari to iOS.
The popup can even appear on systems that don't have the Electrum wallet installed, and for people who have never used it.
The message seen is as follows:
Electrum versions older than 4.0.9 have a vulnerability. Please update Electrum to avoid losing funds.
As you can see in the image above, the popup comes from the BlitzGG app.
Veteran updated his thread to offer context from BlitzGG staff, with the original thread in the BlitzGG subreddit deleted.
A staff member by the name of Marcel has claimed the issue stems from a 'malicious advertisement' added to Google's ad platform, which is served to 'millions of websites'.
Should you see this notification, do not under any circumstances click 'OK'. If you do, it attempts to install an executable file containing the malware.
While Riot Games have promised more skins for League of Legends, two champions remain relatively neglected — both Wukong and Rumble last received a skin over 1,000 days ago.
