This week, headlines blew up with warnings of a design flaw in the CTF subsystem (msctf) of the Windows Text Services Framework that affects all current Windows systems and those going back as far as twenty years.

Last week, a new strain of ransomware hit dozens of targets across Germany. The categorization as ransomware is really a misnomer as, while the attackers do demand a ransom, by that time the victim’s data has already been irreversibly wiped, even if the ransom is paid.

During the period of March to May 2019, Morphisec Labs observed a new, highly sophisticated variant of the ShellTea / PunchBuggy backdoor malware that attempted to infiltrate a number of machines within the network of a customer in the hotel-entertainment industry. It is believed that the malware was deployed as a result of several phishing attempts.

Over the past two weeks, Morphisec Labs has identified an increase in AVE_MARIA malware infecting victims through a variety of phishing methods. One of the downloader components and C2 metadata are similar to those we saw in the Orcus RAT attacks last month and we believe they are by the same threat actor.

Today Adobe disclosed a new Flash zero-day, releasing a patch for the critical vulnerability in an out-of-band update. Successful exploitation gives attackers the ability to execute arbitrary code on the targeted machine, and eventually assume full system control. Morphisec customers are already protected from attacks exploiting this vulnerability.

Over the past three days, Morphisec Labs researchers have discovered a widespread cyber campaign hitting multiple targets. Morphisec researchers dubbed the campaign “Pied Piper”as it delivers various Remote Access Trojan (RAT) payloads via phishing, across multiple countries.

It seems like the rumors of FIN7’s decline have been hasty. Just a few months after the well-publicized indictment of three high-ranking members in August, Morphisec has identified a new FIN7 campaign that appears to be targeting the restaurant industry.

Over the past year, Morphisec and several other endpoint protection companies have been tracking a resurgence in activity from the Cobalt Group. Cobalt is one of the most notorious cybercrime operations, with attacks against more than 100 banks across 40 countries

The Fallout exploit kit, named for its similarities to the once notorious Nuclear exploit kit, already shows signs of reaching the levels of popularity of its namesake. Since its discovery by security researchers at the end of August, Fallout has been seen distributing the SmokeLoader trojan, GandCrab ransomware, CoalaBot, various potentially unwanted programs (PUPs) and, most recently, a new ransomware strain called SAVEfiles.

Fileless malware is a type of a malicious code execution technique that operates completely within process memory; no files are dropped onto the disk. Without any artifacts on the hard drive to detect, these attacks easily evade most security solutions.
