Threat Krebs on Security

The Federal Bureau of Investigation (FBI) and the Cybersecurity and Infrastructure Security Agency (CISA) on Thursday issued a joint alert to warn about the growing threat from voice phishing or attacks coque silicone de huawei p30 lite targeting companies. The advisory came less than 24 hours after coque de telephone huawei p30 pro KrebsOnSecurity published an in depth look at a crime coque iphone xr silicone monde group offering a service that people can hire to steal VPN credentials and other sensitive data from employees working remotely during the Coronavirus pandemic.

COVID 19 pandemic has resulted in coque huawei p9 clapet a mass shift to working from home, resulting in increased use of corporate virtual private networks (VPNs) and elimination of in person verification, the alert reads. mid July 2020, cybercriminals started a vishing campaign gaining access to employee tools at multiple companies with indiscriminate targeting with the end goal of monetizing the access.

The joint FBI/CISA alert (PDF) says the vishing gang also compiles dossiers on employees at the iphone xr coque moto specific companies using mass scraping of public profiles on social media platforms, recruiter and coque p8 lite 2017 huawei clapet marketing tools, publicly available background check services, and open source research. From the alert:

first began using unattributed Voice over Internet Protocol (VoIP) numbers to call targeted employees on their personal cellphones, and later began incorporating spoofed numbers of other offices and employees in the victim company. The actors used social engineering techniques and, in some cases, posed as members of the victim company’s IT help desk, using their knowledge of the employee personally identifiable information including name, position, duration at company, and home address to gain the trust of the targeted employee. actors then convinced the targeted employee that coque huawei p8 lite 2017licorne a new coque custodia cover fundas hoesjes j3 j5 j6 s20 s10 s9 s8 s7 s6 s5 plus edge b35915 spiderman on top j0678 samsung galaxy s10 lite 2020 case VPN link would be sent and required their login, including any 2FA [2 factor authentication] or OTP [one time passwords]. The actor logged the information provided by the employee and used it in real time to gain access to corporate tools using the employee’s account. alert notes that in some cases the unsuspecting employees approved the 2FA or OTP prompt, coque custodia cover fundas hoesjes j3 j5 j6 s20 s10 s9 s8 s7 s6 s5 plus edge d25913 gudetama lazy egg cute 3 samsung galaxy s10 e case either accidentally or believing it was the result of the earlier access granted to the help desk impersonator. In other cases, the attackers were able to intercept the one time codes by targeting the employee with SIM swapping, which involves social engineering people at mobile phone companies into giving them control of the target phone number.

The agencies said crooks use the vished VPN credentials to mine the victim company databases for their customers’ personal information to leverage in other attacks.

actors then used the employee access to conduct further research on victims, and/or to fraudulently obtain funds using varying methods dependent on the platform being accessed, the alert reads. monetizing method varied depending on the company but was highly aggressive with a tight timeline between the initial breach and the disruptive cashout scheme. advisory includes a number of suggestions that companies can implement to help mitigate the threat from these vishing attacks, including:

Restrict VPN connections to managed devices only, using mechanisms like hardware checks or installed certificates, so user input alone is not enough coque iphone xr ete to access the corporate VPN.

Restrict coque silicone p20 lite huawei VPN access hours, where applicable, to mitigate access outside of allowed times.

Employ domain monitoring to track the creation of, or changes to, corporate, brand name domains.

Consider using coque custodia cover fundas hoesjes j3 j5 j6 s20 s10 s9 s8 s7 s6 s5 plus edge d24582 frank ocean blond 4 samsung galaxy s7 case a formalized authentication process for employee to employee communications made over the warm coque iphone 11 public telephone network where a second factor is fishing enjoy periodically coque iphone 11 used to

authenticate the phone call before sensitive huawei p30 lite coque lot information can be discussed.

Improve 2FA and OTP messaging to reduce confusion about employee authentication attempts.

Verify web links do not have misspellings or contain the wrong domain.

Bookmark the coque huawei p10 lite elephant correct corporate VPN URL and do not visit alternative URLs on the coque custodia cover fundas hoesjes j3 j5 j6 s20 s10 s9 s8 s7 s6 s5 plus edge d25248 gohan bape supreme samsung galaxy s10 e case sole basis of an inbound phone call.

Be suspicious of unsolicited phone calls, visits, or email messages from unknown individuals claiming to be from a legitimate organization. If possible, try to verify the caller’s identity directly with the company.

If you receive a vishing call, document the phone number of the caller as well as the domain that the actor tried to send you to and relay this information to law enforcement.

Limit the amount of personal information you post on social networking sites. The internet is a public resource; only post information you are comfortable with anyone seeing.

Evaluate your settings: sites may change their options coque huawei p10 licorne periodically, so review your security and privacy settings regularly to make sure that your choices are still appropriate.

Sure, a reckless individual can log into their corporate account and then hand the computer to their neighbor. But in general the onus is on their employer to secure the coque huawei y7 2019 vampire diaries computing infrastructure end to end.

by the way most developed countries do not mail ballots. They are sent in individual letters to a coque strass huawei p30 pro legally registered domicile, and include a legal certificate that the voter must sign and send back for the ballot to become valid. Sure, there are obviously lots of these letters, but that coque iphone xr avec motif does not make them mailAnother good write up on a everyone should know about subject.

Oh, another article was on Google news about vpn and security. Saying do not trust them. And why.

Like the bullet points at the end of the article, but one should be expanded with the addition of is updates. My favorite is, ms, does change your security settings. It will turn off your firewall to update and not reset your firewall, if you run any antivirus other then me, it will turn it off, and change your preferences to theirs. Which is why I like assistance like God mode. The only thing, is, I wish there was a notepad addition to either me update, or godmode that showed you what settings were just changed by the program updates. But, when suggested in the user groups, it was laughed out. And after every update, it shows that settings needs a rework. And, reboot, after the reboot, investigate what has been added, and shut off, see if it meets your requirements…
