Satan Ransomware Variant Exploits 10 Server-Side Flaws

A new version of ransomware that first surfaced about two years ago is garnering attention for its ability to spread via as many as ten different vulnerabilities in Windows and Linux server platforms.

“Lucky,” as the new malware is called, is a variant of Satan, a data encryption tool that first became available via a ransomware-as-a-service offering in January 2017. Like Satan, Lucky also is worm-like in behavior and capable of spreading on its own with no human interaction at all. Security vendor NSFocus spotted the variant on systems belonging to some of its financial services customers in late November, and described it as likely to cause extensive infections worldwide.

Sextortion Emails now Leading to Ransomware and Info-Stealing Trojans

Sextortion email scams have been a very successful way of generating money for criminals. A sextortion scam is when you receive an email that states someone hacked your computer and has been creating videos of you while you are using adult web sites. The emails then tell you to send them bitcoins or they will share the videos they made with all of your contacts.

A new campaign has been spotted by researchers at ProofPoint that instead of containing a bitcoin address to send a blackmail payment to, they prompt you to download a video they made of you doing certain “activities”. The downloaded zip file, though, contains a executable that will install malware onto the computer.

Iran-Based Hackers Indicted in March Cyberattack on Atlanta

A U.S. grand jury indicted two Iranian nationals over claims they carried out a March ransomware attack against the city of Atlanta, crippling its computer systems and causing millions of dollars in losses. Faramarz Shahi Savandi and Mohammed Mehdi Shah Mansouri used ransomware known as SamSam to infect about 3,789 servers and workstations in Atlanta, the Justice Department said.

The two men, who operated from Iran, were also indicted last week by a federal grand jury in Newark, New Jersey, for a “34-month-long international computer hacking and extortion scheme,” according to the Justice Department.

Ransomware Infects 100K PCs in China, Demands WeChat Payment

Over 100,000 thousand computers in China have been infected in just a few days with poorly-written ransomware that encrypts local files and steals credentials for multiple Chinese online services. The crooks demand the victim a ransom of 110 yuan ($16) in exchange for decrypting the files, payable via Tencent’s WeChat payment service by scanning a QR code.

A report from Chinese security firm Huorong, the malware, dubbed ‘WeChat Ransom’ in some reports, emerged on December 1 and the number of infected systems has grown to over 100,000 as of December 4. The infection rate seems to have accelerated in one day, rising to the above number from just 20,000 a day before.

Cyber security: Hackers step out of the shadows with bigger, bolder attacks

Stealth and secrecy use to be the hallmarks of cyber espionage and cyberwarfare, with spies and hackers sneaking in and out of target networks without leaving a trace or evidence that could be linked back to them. But increasingly, cyber attacks are now carried out in fully public view, and many attackers don’t appear to worry so much about keeping under the radar. Some even seem to go out of their way to make sure they are spotted.

One example of the way cyberattacks have gone public: the WannaCry ransomware caused chaos and made headlines around the world, with many businesses locked out of their PCs by hackers who demanded a bitcoin ransom in exchange for restoring access to data.

Two hospitals in Ohio and West Virginia have been forced to turn away emergency patients after their computer systems were crippled in a ransomware attack over the weekend.
