New Web-Based Credit Card Stealer Uses Telegram Messenger to Exfiltrate Data

New Web-Based Credit Card Stealer Uses Telegram Messenger to Exfiltrate Data

September 02, 2020Ravie Lakshmanan
Cybercriminal groups are constantly evolving to find new ways to pilfer financial information, and the latest trick in their arsenal is to leverage the messaging app Telegram to their benefit. In what's a new tactic adopted by Magecart groups, the encrypted messaging service is being used to send stolen payment details from compromised websites back to the attackers. "For threat actors, this data exfiltration mechanism is efficient and doesn't require them to keep up infrastructure that could be taken down or blocked by defenders," Jérôme Segura of Malwarebytes said in a Monday analysis . "They can even receive a notification in real time for each new victim, helping them quickly monetize the stolen cards in underground markets." The TTP was first publicly documented by security researcher @AffableKraut in a Twitter thread last week using data from Dutch cybersecurity firm Sansec. Injecting e-skimmers on shopping websites by exploiting a known
Maximum Lifespan of SSL/TLS Certificates is 398 Days Starting Today

Maximum Lifespan of SSL/TLS Certificates is 398 Days Starting Today

September 01, 2020Ravie Lakshmanan
Starting today, the lifespan of new TLS certificates will be limited to 398 days, a little over a year, from the previous maximum certificate lifetime of 27 months (825 days). In a move that's meant to boost security, Apple, Google, and Mozilla are set to reject publicly rooted digital certificates in their respective web browsers that expire more than 13 months (or 398 days) from their creation date. The lifespan of SSL/TLS certificates has shrunk significantly over the last decade. In 2011, the Certification Authority Browser Forum (CA/Browser Forum), a consortium of certification authorities and vendors of browser software, imposed a limit of five years, bringing down the certificate validity period from 8-10 years. Subsequently, in 2015, it was cut short to three years and to two years again in 2018. Although the proposal to reduce certificate lifetimes to one year was shot down in a ballot last September , the measure has been overwhelmingly supported by the browser
Cisco Issues Warning Over IOS XR Zero-Day Flaw Being Targeted in the Wild

Cisco Issues Warning Over IOS XR Zero-Day Flaw Being Targeted in the Wild

September 01, 2020Ravie Lakshmanan
Cisco has warned of an active zero-day vulnerability in its router software that's being exploited in the wild and could allow a remote, authenticated attacker to carry out memory exhaustion attacks on an affected device. "An attacker could exploit these vulnerabilities by sending crafted IGMP traffic to an affected device," Cisco said in an advisory posted over the weekend. "A successful exploit could allow the attacker to cause memory exhaustion, resulting in instability of other processes. These processes may include, but are not limited to, interior and exterior routing protocols." Although the company said it will release software fixes to address the flaw, it did not share a timeline for when it plans to make it available. The networking equipment maker said it became aware of attempts to exploit the flaw on August 28. Tracked as CVE-2020-3566 , the severity of the vulnerability has been rated "high" with a Common Vulnerability Scoring
Iranian Hackers Pose as Journalists to Trick Victims Into Installing Malware

Iranian Hackers Pose as Journalists to Trick Victims Into Installing Malware

August 28, 2020Ravie Lakshmanan
An Iranian cyberespionage group known for targeting government, defense technology, military, and diplomacy sectors is now impersonating journalists to approach targets via LinkedIn and WhatsApp and infect their devices with malware. Detailing the new tactics of the "Charming Kitten" APT group, Israeli firm Clearsky said, "starting July 2020, we have identified a new TTP of the group, impersonating 'Deutsche Welle' and the 'Jewish Journal' using emails alongside WhatsApp messages as their main platform to approach the target and convince them to open a malicious link." This development is the first time the threat actor is said to have carried out a watering hole attack through WhatsApp and LinkedIn, which also includes making phone calls to victims, Clearsky noted in a Thursday analysis. After the company alerted Deutsche Welle about the impersonation and the watering hole in their website, the German broadcaster confirmed, "the repor

QakBot Banking Trojan Returned With New Sneaky Tricks to Steal Your Money

August 27, 2020Ravie Lakshmanan
A notorious banking trojan aimed at stealing bank account credentials and other financial information has now come back with new tricks up its sleeve to target government, military, and manufacturing sectors in the US and Europe, according to new research. In an analysis released by Check Point Research today, the latest wave of Qbot activity appears to have dovetailed with the return of Emotet — another email-based malware behind several botnet-driven spam campaigns and ransomware attacks — last month, with the new sample capable of covertly gathering all email threads from a victim's Outlook client and using them for later malspam campaigns. "These days Qbot is much more dangerous than it was previously — it has an active malspam campaign which infects organizations, and it manages to use a 'third-party' infection infrastructure like Emotet's to spread the threat even further," the cybersecurity firm said. Using Hijacked Email Threads as Lures F
Russian Arrested After Offering $1 Million to U.S. Company Employee for Planting Malware

Russian Arrested After Offering $1 Million to U.S. Company Employee for Planting Malware

Hackers always find a way in, even if there's no software vulnerability to exploit. The FBI has arrested a Russian national who recently traveled to the United States and offered $1 million in bribe to an employee of a targeted company for his help in installing malware into the company's computer network manually. Egor Igorevich Kriuchkov , 27-year-old, entered the United States as a tourist and was arrested in Los Angeles after meeting with the unnamed employee of an undisclosed Nevada-based company numerous times, between August 1 to August 21, to discuss the conspiracy. "On or about July 16, EGOR IGOREVICH KRIUCHKOV used his WhatsApp account to contact the employee of victim company and arranged to visit in person in the District of Nevada," the court documents say. "On or about July 28, EGOR IGOREVICH KRIUCHKOV entered the United States using his Russian Passport and a B1/B2 tourist visa." Kriuchkov also asked the employee to participate in
APT Hackers Exploit Autodesk 3ds Max Software for Industrial Espionage

APT Hackers Exploit Autodesk 3ds Max Software for Industrial Espionage

August 26, 2020Ravie Lakshmanan
It's one thing for APT groups to conduct cyber espionage to meet their own financial objectives. But it's an entirely different matter when they are used as "hackers for hire" by competing private companies to make away with confidential information. Bitdefender's Cyber Threat Intelligence Lab discovered yet another instance of an espionage attack targeting an unnamed international architectural and video production company that had all the hallmarks of a carefully orchestrated campaign. "The cybercriminal group infiltrated the company using a tainted and specially crafted plugin for Autodesk 3ds Max," Bitdefender researchers said in a report released today. "The investigation also found that the Command and Control infrastructure used by the cybercriminal group to test their malicious payload against the organization's security solution, is located in South Korea." Although there have been previous instances of APT mercenary gr

Popular iOS SDK Accused of Spying on Billions of Users and Committing Ad Fraud

August 25, 2020Ravie Lakshmanan
A popular iOS software development kit (SDK) used by over 1,200 apps—with a total of more than a billion mobile users—is said to contain malicious code with the goal of perpetrating mobile ad-click fraud and capturing sensitive information. According to a report published by cybersecurity firm Snyk , Mintegral — a mobile programmatic advertising platform owned by Chinese mobile ad tech company Mobvista — includes an SDK component that allows it to collect URLs, device identifiers, IP Address, operating system version, and other user sensitive data from compromised apps to a remote logging server. The malicious iOS SDK has been named "SourMint" by Snyk researchers. "The malicious code can spy on user activity by logging URL-based requests made through the app," Snyk's Alyssa Miller said in a Monday analysis. "This activity is logged to a third-party server and could potentially include personally identifiable information (PII) and other sensitive in
