The Good

A good cybersecurity model helps government and private organizations stay ahead of cyberattacks. Taking an initiative in this aspect, the Coalition to Reduce Cyber Risk (CR2) has collaborated with 37 tech leaders to sign a pledge that aims at improving cybersecurity standards. In parallel, the CISA has announced that the Cybersecurity Maturity Model Certification (CMMC) 2.0 is in the process of making and will be launched in 2023.

  • The Coalition to Reduce Cyber Risk (CR2) along with 37 tech leaders from across eight countries have signed a pledge to improve cybersecurity standards and incorporate them into policies and controls. The adoption of these standards among companies and government agencies is expected to mitigate cyber risks and facilitate economic growth.
  • The Cybersecurity Maturity Model Certification (CMMC) 2.0 is in the process of making and will be launched in 2023, revealed CISA officials. The model aims to bring a unified security standard among contractors linked to the US Department of Defense (DoD).
  • Malwarebytes took down several IP addresses of scammers associated with a profitable IP2Scam tech support campaign. The campaign, which was active since last year, redirected users to fake warning pages via malicious ads.
  • The House appropriations subcommittee has approved a budget of $2.9 billion for CISA in Homeland Security FY2023 Budget Print. The fund will be used to support the agency’s security, infrastructure security, emergency communications, integrated operations, and risk management.

The Bad

The recently discovered Atlassian Confluence flaw remains under attack. Reports suggest that ransomware groups have jumped on the bandwagon to exploit the flaw and launch widespread attacks. Meanwhile, the Sandworm APT used the Follina vulnerability as an attack vector to infiltrate the networks of multiple media organizations in Ukraine. The Monkeypox outbreak has caught the attention of phishers and is now being used as a lure in phishing campaigns.

  • The Gallium APT group has been linked to a new attack campaign that distributed a new remote access trojan named PingPull. The attacks were aimed at financial and government organizations in Afghanistan, Australia, Belgium, Cambodia, Malaysia, Mozambique, the Philippines, Russia, and Vietnam.
  • Check Point researchers uncovered a new Iranian-based spear-phishing attack targeting former Israeli officials, high-ranking military personnel, think tanks, research fellows, and Israeli citizens. The attack hijacked existing email conversations of several trusted parties to trick the recipients. Associated with Phosphorous APT, the ultimate goal of the attack was to pilfer PII and other identity documents.
  • Phishers are using the Monkeypox outbreak as a new lure to trick users into sharing their personal information. They are sending phishing emails to company employees for ‘mandatory monkeypox safety awareness training.’
  • AvosLocker and Cerber2021 are among the first few ransomware groups that were found exploiting the recently disclosed RCE vulnerability affecting Atlassian Confluence Server to gain access to corporate networks. They used the POC exploits of the flaw to launch attacks.
  • A misconfigured Travis CI API had leaked thousands of authentication tokens and other security-sensitive secrets. Many of these leaks could allow hackers to access the private accounts of developers on GitHub, Docker, AWS, and other code repositories.
  • Ukraine CERT has warned that the Russian hacking group Sandworm is exploiting the Follina vulnerability in a new campaign to target various media organizations in Ukraine. The campaign is carried out via phishing email and has targeted more than 500 recipients.

  • An unprotected Elasticsearch server belonging to Malaysia-based StoreHub company had reportedly exposed data of about 1 million customers. The leaked data also included information from thousands of retail stores and restaurants.

New Threats

A new threat to the security of cryptographic software has come to the notice of researchers. Called Hertzbleed, the attack can enable attackers to steal full cryptographic keys by exploiting flaws in modern Intel and AMD processors. There is also an update on the recent activities of the BlackCat RaaS operation. Microsoft revealed that several cybercrime gangs such as DEV-0237 and DEV-0504 have been hiring the ransomware service to launch attacks. Additionally, the BlackCat group has taken its extortion tactic to a new level to put more pressure on victims. A new phishing tool capable of spoofing Microsoft Office and Google is also gaining traction among cybercriminals.

  • A team of academics from US universities has published a research paper detailing a new side-channel attack called Hertzbleed. Tracked as CVE-2022-23823 and CVE-2022-24436, the flaws affect all Intel processors and several processors from AMD. In the worst case, the flaws can allow attackers to extract cryptographic keys from remote servers.
  • Avast has published details about a new kernel rootkit named Syslogk which is inspired by Adore-Ng rootkit. Syslogk is being used to target Linux systems.
  • BlackCat group has updated its extortion tactic by publishing stolen victims’ data on the public internet. With this, the group plans to put more pressure on organizations that deny paying the ransom. Furthermore, Microsoft has reported that the attackers, among other ransomware groups, have adopted the RaaS operation to enable cybercriminal groups like DEV-0237 and DEV-0504 to perform more attacks.
  • The PureCrypter malware loader has been updated with several new modules to target more resources. One of these functionalities can enable them to use Telegram as a channel to send malware.
  • Several malicious apps capable of spreading adware and information-stealing malware were found on the Google Play Store. Five of these are still active and have amassed over two million downloads. They are PIP Pic Camera Photo Editor, Wild & Exotic Animal Wallpaper, ZodiHoroscope, PIP Camera 2022, and Magnifier Flashlight.

  • Proofpoint researchers have discovered a dangerous ransomware attack that abuses a functionality in Office 365 or Microsoft 365 to encrypt files stored on SharePoint and OneDrive.
  • A WooCommerce credit card skimmer was found leveraging a Telegram bot to pilfer the stolen data and later, sell it on the black market - resulting in fake transactions on victims’ credit cards.
  • Hackers have developed a new Android malware strain, dubbed MaliBot. The information-stealing trojan was spotted in the wild targeting online banking and crypto wallet users in Italy and Spain. It is being distributed via counterfeit websites hosting cryptocurrency mining apps such as Mining X or The CryptoApp.
  • Panchan, a new Golang-based P2P botnet, has been targeting the education sector since March 2022. Designed to mine cryptocurrencies, the bot was observed using XMRig and nbhash miners that aren’t extracted to the disk to avoid detection.
