Ongoing Campaigns

Scammers attempted to trick YouTubers into giving up passwords

  • The owner of the TeslaJoy channel on YouTube received an email pretending to be from YouTube support, stating that her channel was in violation of several YouTube policies. In order to solve the issue, the email stated that analysis was needed, which would require information, including the victim’s password.
  • The scammers added the incorrect postal address at the bottom of the email and delivered the email to TeslaJoy’s public email address. These instances, among others, meant that the victim did not fall for the scam.



GandCrab ransomware targets Japanese manufacturing firm

  • Cybereason researchers reported on a new campaign in which GandCrab ransomware was used to target an international company based in Japan. The researchers concluded that this campaign demonstrates how the perpetrators have combined multiple evasive techniques to achieve a successful ransomware infection.
  • The attack began with a malicious Korean document delivered via a phishing email. Once users enable the document’s macros, a multi-stage infection process begins, that involves VBA code, WMI objects, JavaScript and the use of a Squiblyoo technique variation to bypass Windows AppLocker.
  • The last stage involves connecting to pastebin[.]com to download the final payload containing GandCrab. According to the researchers, the Pastebin URL and page content seem to be undetected by antivirus vendors.

Turla espionage group uses LightNeuron malware to target Microsoft Exchange servers

  • ESET researchers investigated a sophisticated backdoor dubbed LightNeuron, used by the Turla APT group, that has been targeting Microsoft Exchange mail servers since at least 2014. Victims of this campaign include an Eastern European ministry of foreign affairs, a Middle Eastern regional diplomatic organisation and an unknown organisation in Brazil.
  • LightNeuron is believed to be the first malware specifically targeting Microsoft Exchange email servers. It uses steganography to hide its commands inside a PDF file or a JPG image. It also uses a Transport Agent to achieve persistence, something that has not been observed before.
  • Through their investigation, the researchers were led to believe that the perpetrators are based in Russia.

  • Individuals in southern Wisconsin have been warned against a phishing scam that involves text messages, claiming to have information on a person’s condition, that include a phishing link.



Lucy Security Simulated Phishing template allegedly used in recent phishing attack

  • Upon further investigation, it was found that Lucy’s Simulated Phishing software was not involved in the attack, but the perpetrators did copy some of Lucy’s designs to use for malicious purposes.



JASK report on new cryptojacking campaign led by Outlaw threat group

  • The campaign was discovered in the wild in November, 2018, after firewalls detected brute force authentication attempts on an educational institution’s network’s SSH server. Once the SSH was breached, the researchers assessed that malicious payloads were being installed and operated from.
  • A malicious Perl script was identified and found to be an obfuscated version of Shellbot IRC malware, which, when run, unpacks functions and makes a connection to the attacker’s IRC server for C2. Once a connection was established, XMR-Stak is downloaded and installed on the victim’s machine to generate cryptocurrency.
  • JASK attributed the attack to the Outlaw cybercrime group due to several similarities spotted between this attack and previous attacks attributed to the group. In this case the only difference in their attack infrastructure was that they added obfuscation to the Perl script.



Scammers adopt cloud services to find new victims

  • Netskope researchers have identified a new technique being used by scammers to reach potential victims, in which they send links to common services such as AWS, Google Docs, Alibaba Cloud, and more.
  • The researchers have observed scammers hosting tech support scams in Alibaba, AWS and Azure, ‘rotating from one object store to another, using seemingly arbitrary names’.
  • Scammers were also observed abusing Google Docs to create presentations and sharing them through phishing and smishing. The presentations act as bait and hide the malicious link. Using Google Doc links also enables attackers to bypass spam filters.

General News

Researcher discovers new method to track mouse movements bypassing Ad blockers

  • A new method has been discovered that allows websites to track user’s mouse movements of visitors by using HTML and CSS, which can bypass tracking protections.
  • Most tracking is accomplished using JavaScript scripts that are loaded into websites and advertisements, that can be blocked by Ad blockers. In this case, instead of using JavaScript, HTML and CSS is used to watch mouse movements occurring in one browser window from within another browser window.
  • Researcher Davy Wybiral did this by creating a grid of HTML DIVs that use CSS :hover selectors to request a new background image when the mouse moves over a box on the grid. Because the image requests are done in the background, the browser does not indicate that they are making a connection and therefore requests are hidden from the user.



DeepDotWeb seized by FBI for taking commissions from illegals sites

  • The dark web directory DeepDotWeb has been seized and arrests have been made following allegations that affiliate commissions were generated by referring traffic to illegal sites. DeepDotWeb acted as a directory for websites running on Tor, which offered news related to the dark web, but also offered a directory to dark web sites, including marketplaces that sold illegal services and weapons.
  • An operation run by the FBI, Europol and Federal law enforcement agencies from Germany, Israel, the Netherlands and Brazil culminated in members of the directory being arrested, and the website being seized.



SafeGuard Cyber releases new data on Russian social media influence

  • Russia is reportedly continuing to attempt to meddle in elections, with its latest campaign involving the spread of misinformation via social media pertaining to the EU parliamentary elections at the end of May. Malicious actors including bots, trolls and hybrids are exacerbating existing tensions in relation to contentious issues in order to try and influence the public’s perception of events.

Boeing admits knowing about 737 MAX software issue a year prior to accidents
