Microsoft Issues Fixes for 115 Security Holes Across Various Windows Operating Systems and Associated Software

Microsoft released updates to plug 115 security holes in its various Windows operating systems and associated software, twenty-six of which are rated critical, but none of which are considered zero-day flaws. One flaw fixed this month in Microsoft Word (CVE-2020-0852) could be exploited to execute malicious code on a Windows system just by getting the user to load an email containing a booby-trapped document in the Microsoft Outlook preview panel. Microsoft also fixed a flaw in a new component Microsoft debuted this year called Application Inspector, a source code analyzer designed to help Windows developers identify “interesting” or risky features in open source software (such as the use of cryptography, connections made to a remote entity, etc.).

Microsoft Issues Fixes for 113 Security Vulnerabilities Including Three Zero-Day Flaws Exploited in the Wild, Adobe Issues Skinny Bundle of Updates but None for Flash

In its monthly security fixes collectively known as Patch Tuesday, Microsoft released updates to fix 113 security vulnerabilities across its Windows operating systems and related software, including at least three flaws that are actively being exploited. The three flaws exploited in the wild include CVE-2020-1020, a remotely exploitable bug in the Adobe Font Manager library that was first detailed in late March.  The Adobe Font Manager library is the source of yet another zero-day flaw — CVE-2020-0938. The final zero-day flaw fixed is a slightly less dangerous elevation of privilege vulnerability (CVE-2020-1027) affecting Windows 7 and Windows 10 systems. Adobe issued up a skinny bundle of updates for Cold Fusion, Adobe After Effects, and Adobe Digital Editions, although no fixes for its usually problematic Flash player.

FBI Arrested Russian Security Researcher for Running, a Shopify-Like Marketplace for Stolen Online Service Account Credentials

The FBI arrested Russian computer security researcher Kirill V. Firsov on March 7 at New York’s John F. Kennedy Airport on suspicion of operating, a vast  Shopify-like marketplace for buying and selling stolen account credentials for thousands of popular online services and store. Prosecutors with the U.S. District Court for the Southern District of California allege Firsov was the administrator of, an online platform that hosted more than 24,000 shops for selling stolen or hacked usernames and passwords for a variety of top online destinations. The indictment says Firsov is responsible for $17 million worth of stolen credential sales since its inception in 2013. Firsov is slated to be arraigned later this week, when he will face two felony counts, aiding and abetting the unauthorized solicitation of access devices, and aiding and abetting trafficking in “false authentication features.

New Automated Zoom Meeting Discovery Tool ‘zWarDial’ Shows Many Zoom Meetings Are Unprotected by Passwords as FBI Issues Warning of ‘Zoombombing’

According to data gathered by a new automated Zoom meeting discovery tool dubbed “zWarDial,” a substantial number of meetings at major corporations are not being protected by a password, which could lead to those meetings being “Zoom bombed” or eavesdropped upon. Each Zoom conference call is assigned a Meeting ID that consists of 9 to 11 digits. Naturally, hackers have figured out they can simply guess or automate the guessing of random IDs within that space of digits. The incidence of Zoombombing has reached such a peak that the FBI issued a warning earlier this week about the problem and guided how to keep meetings secure.

Microsoft Issues 111 Software Updates for Windows, Windows-Based Programs, Adobe Releases Two Dozen Patches for Acrobat and Reader

Microsoft issued software updates to plug at least 111 security holes in Windows and Windows-based programs, the third month in a row that Microsoft has pushed out patches for more than 110 flaws. Sixteen of the bugs are labeled critical, but virtually all of the non-critical flaws in this month’s batch earned Microsoft’s “Important” rating. Adobe also issued its Patch Tuesday updates for some of its products. An update for Adobe Acrobat and Reader covers two dozen critical and important vulnerabilities, but once again, there were no security fixes for Adobe’s problematic Flash player.

Europe’s Largest Private Hospital Operator Fresenius Hit by Ransomware Attack, Snake Ransomware Indicated

Against a backdrop of increasing attacks against healthcare providers during the coronavirus pandemic, Europe’s largest private hospital operator, Fresenius, which is also a significant provider of dialysis products and services currently in high demand, has been hit in a ransomware attack. The company said the attack had forced the shut down of some system, but that patient care remains unaffected. One employee said, though, that the attack had affected every part of the company’s operations around the globe and the malware used was the Snake ransomware, a relatively new strain first detailed earlier this year. The company confirmed the attack but declined to answer questions about specific aspects of it.

Romanian ATM Skimming Group in Mexico Has Been Protected by Senior Government Attorney Complaint Alleges

A group of Romanians operating an ATM company in Mexico suspected of bribing technicians to install sophisticated Bluetooth-based skimmers in cash machines has enjoyed legal protection from a senior anti-corruption official in the Mexican attorney general’s office, according to a new complaint filed with the government’s internal affairs division. The complaint centers on Camilo Constantino Rivera, who heads the unit in the Mexican Special Prosecutor’s office responsible for fighting corruption, and alleges that his brother has served as a security escort and lawyer for Floridan Tudor, the reputed boss of a Romanian crime syndicate recently targeted by the FBI for running an ATM skimming and human trafficking network that operates throughout Mexico and the United States. As a side note, a text exchange seems to indicate Tudor’s group contemplated taking a hit on the life Brian Krebs for uncovering their operation in a 2015 investigation.

Cybercriminals on the Dark Web Are Running Vulnerability Testing Services to Help Malware Authors Find and Fix Flaws in Their Code

Cybercriminals on the dark web, such as one called RedBear, the administrator of a Russian-language security site called Krober[.]biz, operate malware testing services to help malware authors, and those who lease or buy malware services find and fix the flaws in their code. Among the malware types reviewed for flaws by these services are bot admin panels, code injection panels, shell control panels, payment card sniffers, traffic direction services, exchange services, spamming software, doorway generators, and scam pages. Among the high-profile malicious tools examined for flaws by RedBear are the Black Energy DDoS bot administration panel, malware loading panels tied to the Smoke and Andromeda bot loaders, the RMS, and Spyadmin trojans; and a popular loan scan script.

Fraudsters Are Stealing Potentially Hundreds of Millions From State Unemployment Programs

A sophisticated Nigerian crime ring is exploiting multiple state unemployment insurance programs at a time when they are under tremendous strain, committing fraud and stealing potentially hundreds of millions of dollars earmarked for averting an economic collapse, according to a new alert issued by the U.S. Secret Service. The crime ring has been filing unemployment claims in different states using Social Security numbers and other personally identifiable information (PII) belonging to identity theft victims, and “a substantial amount of the fraudulent benefits submitted have used PII from first responders, government personnel and school employees,” a memo from the Secret Service says. “The primary state targeted so far is Washington, although there is also evidence of attacks in North Carolina, Massachusetts, Rhode Island, Oklahoma, Wyoming, and Florida,” according to the memo. Many states don’t have enough controls in place to detect patterns that might help better screen out fraudulent unemployment application experts say.

New Variant of Mirai Botnet Malware Exploits Previously Patched Zero-Day Flaw in Zyxel’s Routers, VPN Firewalls and NAS Devices

Researchers at Palo Alto Networks have spotted a zero-day vulnerability in Taiwanese vendor Zyxel’s routers and VPN firewall products that fixed by the manufacturer being exploited by a new variant of Mirai, a malware strain that targets vulnerable Internet of Things (IoT) devices for use in large-scale attacks and as proxies for other cybercrime activity. The experts at Palo Alto Networks’s Unit 42 said that their sensors detected the new Mirai variant, dubbed Mukashi, on March 12.  This new strain targets CVE-2020-9054, a critical flaw that exists in many VPN firewalls and network-attached storage (NAS) devices made by Zyxel, which boasts around 100 million devices deployed worldwide. IoT systems infected by Mukashi report back to a control server, which can be used to issue new instructions such as downloading additional software or launching distributed denial of service (DDoS) attacks. Zyxel issued a patch for the flaw on February 24, but the update did not fix the problem on many older Zyxel devices, which are no longer being supported by the company. Zyxel said to disconnect those devices from the internet.
