It is planning on selling those to compensate the victims. In other news, the U.S. Treasury Department and Israel announced to form a task force that would deal with the burgeoning ransomware threats.

• The U.S. Department of Justice enforcement will start the liquidation of the $57 million worth of cryptocurrency seized from BitConnect as a means of restitution to the victims of the fraud committed by the platform. This liquidation is the largest single cryptocurrency recovery ever made by the U.S. to date. While the FBI and IRS-Criminal Investigation are examining the case, the Postal Inspection Service is assisting with the liquidation.

The platform also blocked three hacking groups linked to the Syrian government.
• The CISA released a set of playbooks that contain standardized response procedures for U.S. federal agencies to mitigate cybersecurity incidents and vulnerabilities. The playbooks include how agencies should manage cybersecurity incidents and vulnerabilities and manage related processes such as preparation, investigation, containment, reporting, and remediation.

The Bad

Coming to the bad parts, the week saw quite a lot of malicious cyber activity. Let’s start with Candiru, the Israeli spyware vendor, that reportedly conducted watering hole attacks in the U.K and the Middle East. More details on the Robinhood breach came forth as the data of 7 million customers was put up for sale on a hacking forum. The worst of it all comes in the form of Emotet, which is supported by TrickBot in its apparent comeback after an extensive takedown by global law enforcement authorities. Seems like malware attacks are about to rise.

• Ransomware gangs are showing interest in purchasing zero-day exploits that are available on dark forums. They are ready to offer up to $10 million to compete with state-backed actors, who are the traditional buyers of zero-day exploits. Moreover, instead of selling the vulnerability, the attacker can lease it out to less sophisticated attackers - bringing exploit-as-a-service to the cybercriminal ecosystem.
• A malicious campaign is leveraging a legitimate domain owned by the Myanmar government in a technique, dubbed domain fronting, used to evade detection by routing communications to a server controlled by the attacker. First observed in September, the threat executed Cobalt Strike payloads to launch further attacks.
• The Israeli spyware vendor Candiru, who was put on an economic blocklist by the U.S. government, was allegedly involved in watering hole attacks against targets in the Middle East and the U.K. Some victimized websites also belong to Hezbollah, the Iranian Ministry of Foreign Affairs, the Syrian Ministry of Electricity, Yemeni Ministries of Interior and Finance, and aerospace and defense companies in South Africa and Italy.
• The data of almost 7 million Robinhood customers are being sold on a popular hacking forum. The data includes email addresses of 5 million customers; full names of the remaining 2 million; name, zip code, and dates of birth of 300 people; and extensive account details of 10 customers. In a post, the adversary posted that the data is selling for at least five figures.
• StripChat, an adult cam site, underwent a breach in which the personal data of millions of adult models and users was leaked. The breach was caused due to a passwordless Elasticsearch database left exposed between November 4 and 7. Data of 65 million registered users, 421,000 models broadcasting on the site, 134 million transactions, and 719,000 chat messages were leaked.
• Researchers from various firms revealed that TrickBot is aiding Emotet to get back into the swing of things by installing the latter into compromised systems. The campaign has been dubbed Operation Reacharound to reconstruct Emotet by using TrickBot’s infrastructure. Moreover, the new Emotet comes with an updated command buffer and can execute binaries in multiple ways.
• A phishing campaign targeted more than 125 large TikTok accounts across the world. Besides individual account holders, the campaign targeted talent agencies, social media production studios, brand-consultant agencies, and influencer management companies. The accounts had tens of millions of followers and the perpetrators remain unknown.
• Retail giant Costco confirmed a card skimming attack that affected less than 500 users. Around five skimmers were planted on payment card devices across four Chicago-based warehouses. This enabled attackers to capture information such as names, card numbers, CVV, and expiration dates. While the company believes that the attack was conducted in August, it has not yet made clear how long the card skimmers were active.
• A hacker—claiming to be from a made-up Cyber Threat Detection and Analysis Group at a U.S. federal executive department—was found sending spam emails to at least 100,000 people from an FBI email server. The emails were sent to website admins listed on the American Registry for Internet Numbers. Nevertheless, the hacker wasn’t able to access FBI files.

New Threats

“Baby shark doo, doo, doo, doo.” There’s a baby Shark(Bot) in the threat landscape. The Android banking trojan has already ensnared victims associated with 27 financial organizations across the U.K, the U.S., and Italy. While we are on the topic of trojans, we must tell you that GravityRAT is back in a new malware campaign that is targeting high-profile Indian officials. Attacks on WordPress seem to be ceaseless as another 300 sites were hacked and threatened with a fake ransomware notice.

• A highly skilled group of threat actors—RedCurl—attacked a large Russian wholesale company for the second time this year. The group focuses on cyberespionage and is responsible for at least 30 attacks in Russia, the U.K, Germany, and Norway, among others. Prior to exfiltrating corporate data, the gang stays undetected for a period of two to six months.
• Around 300 WordPress sites were hacked in a new wave of attacks to show fake encryption notices, trying to lure the owners into paying a ransom of 0.1 BTC for restoration. However, it was discovered that this was a fake ransomware attack as the websites were not encrypted, rather a plugin was altered to display the ransom note.
• A security researcher demonstrated a new HTTP header smuggling attack that could be used against the AWS API Gateway. The attack leverages the security weakness of the API to deploy malicious requests or launch attacks. This method creates a mutation in the header request that is to be sent to backend infrastructure with no processing by a trusted frontend service.
• Moses Staff, a new politically-motivated threat group, has been targeting Israeli organizations since September, with an aim to leak sensitive data and no ransom demand. First discovered in October, the threat actor followed in the footsteps of Pay2Key and Black Shadow groups. The gang breaches networks by abusing old, unpatched vulnerabilities.
• A new Android banking trojan, dubbed SharkBot, was discovered by Cleafy and ThreatFabric. Active at least since October, the malware has targeted users of 27 banking and cryptocurrency apps in the U.K, the U.S., and Italy to exfiltrate funds. SharkBot exploits Accessibility Services to pilfer login credentials, current account balance, and personal information.
• Cybercriminals have started using bait attacks as a new technique to make their phishing campaigns more effective. According to a report by Barracuda, 35% of organizations were targeted by bait attacks in September. Also known as reconnaissance attacks, bait attacks are emails that either have very short content or no content at all. As they don’t contain any malicious links, traditional phishing detectors cannot defend against these attacks.
• In a new malware campaign, GravityRAT is targeting high-profile Indian individuals, disguised as an end-to-end encrypted chat application, dubbed SoSafe Chat. The malware requests 42 permissions, out of which, 13 can be exploited to conduct malicious activities such as reading mobile data and obtaining device location. Earlier reports suggest that GravityRAT previously targeted Windows machines.
• The BrazKing Android banking trojan has resurfaced with dynamic banking overlays and a new implementation trick. The latter allows the malware to operate without requesting risky permissions. BrazKing abuses Accessibility Services to read texts and contact lists, programmatically dissect the screen instead of capturing screenshots, and manipulate banking apps with its RAT functionality.
