Our favorite Sr. Threat Researcher, @FredFunk, is back with another round of Weekly Threat News. This week, Kelvin discusses the Monero hack, a brand new term DDoSAS (DDoS as a service) thanks to Sergiy P. Usatyuk, and ransomware continues to plague hospitals and governments.

Booter Boss Banged Up for 13 Months

DDoS attacks can be used for many malicious purposes. Whether it’s bringing down major British political party websites or cheating at online games, DDoS attacks have been making headlines recently. The arrest and conviction of Sergiy P. Usatyuk should worry other criminals who sold DDoS for hire services. As is often the case in the cybercrime sphere, justice hasn’t been swift and the charges related to events in August 2015 to November 2017 where Usatyuk is said to have earned a little over half a million US dollars.

Coin Stealer Found in Monero Linux Binaries from Official Site

Monero is one of the most popular cryptocurrencies in the world.

It’s website “getmonero.org” was compromised and coin stealing malware was put up on the site which has been seen stealing coins from victims. As far as hacks go this is brazen and very effective. Monero to their credit, seem to have reacted fast to the breach and have cleaned up the site and their binaries as well as issuing a warning to users.

 

“Yesterday a GitHub issue about mismatching hashes coming from this website was opened. A quick investigation found that the binaries of the CLI wallet had been compromised and a malicious version was being served. The problem was immediately fixed, which means the compromised files were online for a very short amount of time. The binaries are now served from another, safe, source. See the reddit post by core team member binaryfate.

It's strongly recommended to anyone who downloaded the CLI wallet from this website between Monday 18th 2:30 AM UTC and 4:30 PM UTC, to check the hashes of their binaries. If they don't match the official ones, delete the files and download them again. Do not run the compromised binaries for any reason.”

New NextCry Ransomware Encrypts Data on NextCloud Linux Servers

Ransomware usually entails encrypting data on Windows machines or their share drives. The criminal practice of encrypting valuable data before demanding a ransom is seen elsewhere, however. Nextcloud is a file sync and share service that has seen some weaknesses in its security and default configuration exploited by a new ransomware campaign. The malicious encryption affects the cloud copies of a victim’s files and since the local copies they have are synced (read replaced) by the encrypted versions they risk losing their backup and original copies.

Fake Windows Update Spam Leads to Cyborg Ransomware and Its Builder | Trustwave

Cyborg ransomware is being pushed by fake Microsoft update emails. Updates are important for security and as well as causing damage in the short term, fake updates undermine the general confidence people have updating, and this leads to weaker security as a whole. The sheer number of updates that we all see on a day-to-day basis means that users are unlikely to spend much time investigating any notifications

Keyloggers typically read the keys pressed on a machine so that they can steal valuable information such as credit cards numbers and credentials. They may also steal clipboard data and other information too. We haven’t been hearing much about keyloggers in recent years so the surging reports of the Phoenix keylogger is surprising.

This is the first time this has ever happened. Getmonero.org has had a clean track-record of safe downloads for almost a decade. So whoever pulled this off was -incredibly- talented. Hats off to the Monero team to fixing this as fast as they did - hopefully not too many funds were lost before the fix. What do you guys think about Monero/Crypto? Are you interested in Cryptocurrency and want more news from us about this space? I’d love some discussion on these topics below - let me know what you think!
